FORWARD In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading."1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with hypercholesterolemia is indexed in search engines, such as www.google.com or others, a non-systematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about hypercholesterolemia, using the most advanced research tools available and spending the least amount of time doing so. In addition to offering a structured and comprehensive bibliography, the pages that follow will tell you where and how to find reliable information covering virtually all topics related to hypercholesterolemia, from the essentials to the most advanced areas of research. Public, academic, government, and peer-reviewed research studies are emphasized. Various abstracts are reproduced to give you some of the latest official information available to date on hypercholesterolemia. Abundant guidance is given on how to obtain free-of-charge primary research results via the Internet. While this book focuses on the field of medicine, when some sources provide access to non-medical information relating to hypercholesterolemia, these are noted in the text. E-book and electronic versions of this book are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). If you are using the hard copy version of this book, you can access a cited Web site by typing the provided Web address directly into your Internet browser. You may find it useful to refer to synonyms or related terms when accessing these Internet databases. NOTE: At the time of publication, the Web addresses were functional. However, some links may fail due to URL address changes, which is a common occurrence on the Internet. For readers unfamiliar with the Internet, detailed instructions are offered on how to access electronic resources. For readers unfamiliar with medical terminology, a comprehensive glossary is provided. For readers without access to Internet resources, a directory of medical libraries, that have or can locate references cited here, is given. We hope these resources will prove useful to the widest possible audience seeking information on hypercholesterolemia. The Editors

CHAPTER 1. STUDIES ON HYPERCHOLESTEROLEMIA Overview In this chapter, we will show you how to locate peer-reviewed references and studies on hypercholesterolemia.
The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and hypercholesterolemia, you will need to use the advanced search options. First, go to http://chid.nih.gov/index.html. From there, select the “Detailed Search” option (or go directly to that page with the following hyperlink: http://chid.nih.gov/detail/detail.html). The trick in extracting studies is found in the drop boxes at the bottom of the search page where “You may refine your search by.” Select the dates and language you prefer, and the format option “Journal Article.” At the top of the search form, select the number of records you would like to see (we recommend 100) and check the box to display “whole records.” We recommend that you type “hypercholesterolemia” (or synonyms) into the “For these words:” box. Consider using the option “anywhere in record” to make your search as broad as possible. If you want to limit the search to only a particular field, such as the title of the journal, then select this option in the “Search in these fields” drop box. The following is what you can expect from this type of search: •
Effect of Garlic on Hypercholesterolemia in Renal Transplant Patients Source: Transplantation Proceedings. 30(1): 189-191. February 1998. Contact: Available from Appleton and Lange. P.O. Box 86, Congers, NY 10920-0086. (203) 406-4623. Summary: Hyperlipidemia is a common problem in renal transplant patients and the treatment options have proven difficult. Thus it is desirable to identify safe and effective alternative modalities. This article reports on a study that explored the use of garlic as an herbal medicine to reduce cholesterol levels in renal transplant patients. The study included 35 renal transplant patients with a total serum cholesterol of greater than 240 mg per dL and LDL cholesterol of greater than 160 mg per dL. All participants had
4
Hypercholesterolemia
stable renal allograft function for more than a 6 month period. Patients were instructed in a Step One National Cholesterol Education Program reduction diet and randomized to receive a 12 week course of either placebo or matching garlic tablets at a dose of 680 mg two times a day. Garlic was effective in decreasing both total and LDL cholesterol levels. This benefit was apparent after 6 weeks of therapy and sustained at 12 weeks. In contrast, total cholesterol and LDL cholesterol levels did not change significantly in the placebo group. In general, garlic therapy was well tolerated. The response to garlic was somewhat less than that reported in the metanalysis in which garlic was found to decrease total cholesterol by about 9 percent. However, it is possible that even small decrements in cholesterol may have a long term benefit, particularly in a population that is at higher risk for coronary disease. And, although garlic had significant beneficial effects, treated patients still had hyperlipidemia severe enough to consider the addition of standard pharmacotherapy. 1 figure. 2 tables. 16 references. •
Association Between Hypercholesterolemia, Cardiovascular Disease and Severe Periodontal Disease Source: Journal of Clinical Periodontology. 28(9): 865-868. September 2001. Contact: Available from Munksgaard International Publishers Ltd. Commerce Place, 350 Main Street, Malden, MA 02148-5018. (781) 388-8273. Fax (781) 388-8274. Summary: Premature death in men is known to be significantly associated with coronary heart disease (CHD). More and more studies are pointing toward a possible association between periodontal disease and increased risk of cardiovascular disease. The association of poor oral hygiene and atherosclerosis (hardening of the arteries) can be explained by the effect of chronic inflammatory disease on blood rheology (altered flow and contents). This article reports on a study undertaken to assess the relationship between CHD and periodontal disease. The study population included 1094 Israeli army service men aged 26 to 53 years (mean 39 years plus or minus 5 years). The study group comprised 151 subjects classified as having CHD, i.e., myocardial infarction and or anginal syndrome with angiographic evidence of significant coronary disease, or suffer from atherosclerotic risk factors, i.e., diabetes (fasting glucose) and hypertension (high blood pressure) according to strict, well established criteria. Blood levels of cholesterol and triglycerides were also determined. The severity of periodontal disease was assessed by the aid of CPITN (community periodontal index of treatment need). Statistical analysis showed a significant association of CPITN score 4 with hypercholesterolemia (high levels of cholesterol in the blood) and a possible association with CHD. The authors conclude by proposing the generation of higher cholesterol blood levels as a possible link between chronic periodontal inflammation and atherosclerosis. 3 tables. 28 references.

Treatment of Hypercholesterolemia and Combined Hyperlipidemia with Simvastatin and Gemfibrozil in Patients with NIDDM: A Multicenter Comparison Study Source: Diabetes Care. 21(4): 477-481. April 1998. Contact: Available from American Diabetes Association. 1701 North Beauregard Street, Alexandria, VA 22311. (800) 232-3472. Website: www.diabetes.org. Summary: This article describes a double-blind, double-dummy study that investigated the lipid-lowering efficacy of simvastatin and gemfibrozil in Finnish patients who had type 2 diabetes and combined hyperlipidemia (CHL) or isolated hypercholesterolemia (IHC). Patients with primary dyslipidemia and type 2 diabetes treated with oral hypoglycemic agents and insulin, alone or in combination, were recruited from 10

Finnish centers participating in the study. After a 4-week placebo run-in period, they were randomly assigned to simvastatin or gemfibrozil. The 47 patients in the simvastatin group received 10 milligrams (mg) once a night for 8 weeks, 20 mg for the next 8 weeks, and 40 mg for the third 8-week period. The 49 patients in the gemfibrozil group received 600 mg twice a day throughout the 24 weeks. The lipid-lowering efficacy of both drugs was compared in all patients, as well as separately in patients with CHL and IHC. Results show that simvastatin reduced low density lipoprotein (LDL) and total cholesterol and the LDL-to-high density lipoprotein (HDL) cholesterol ratio more effectively in all patients, whereas gemfibrozil was more effective in elevating HDL cholesterol and decreasing triglyceride levels. The effects differed according to lipid phenotype at baseline. Simvastatin decreased LDL cholesterol levels by 30 to 40 percent in both phenotypes. Gemfibrozil caused a 15 percent reduction in LDL cholesterol in IHC but no change in CHL patients. Simvastatin produced 15 to 30 percent reductions in triglyceride levels in CHL but no change in IHC patients. Gemfibrozil caused reductions in triglycerides in CHL and in IHC patients, with 12 to 18 percent increases in HDL cholesterol in these groups. The article concludes that simvastatin is useful both in CHL and IHC patients, whereas gemfibrozil can be used in patients with high triglyceride and low or normal LDL cholesterol levels. 1 appendix. 2 figures. 3 tables. 26 references.

Hypercholesterolemia in Diabetes and Glucose Intolerance in the U.S. Population Source: Diabetes Care. 14(5): 366-374. May 1991. Summary: This article reports on the prevalence of hypercholesterolemia, according to the guidelines of the National Cholesterol Education Program, which has been determined in a national survey of diabetes and glucose intolerance. Rates of elevated total cholesterol in people with diabetes in the United States are only slightly greater than in those without diabetes after adjusting for age and sex. Nevertheless, high or borderline high total cholesterol is common in diabetes and is present in 70 percent of adults with diagnosed diabetes and 77 percent with undiagnosed diabetes. The authors discuss the findings as they apply to risks for coronary heart disease. The authors conclude that investigation of blood lipid levels and coronary heart disease risk factors should be routine in all patients with diabetes, and treatment strategies should include management of lipid disorders and the multiple other risk factors for coronary heart disease that are highly prevalent in these patients. 2 figures. 7 tables. 50 references.

Effects of Psyllium on Glucose and Serum Lipid Responses in Men with Type 2 Diabetes and Hypercholesterolemia Source: American Journal of Clinical Nutrition. 70(4): 466-473. October 1999.

Summary: Water soluble dietary fibers decrease postprandial (after a meal) glucose (sugar) concentrations and decrease serum cholesterol concentrations. This article reports on a study examining the effects of administering psyllium to men with type 2 diabetes. Psyllium is a viscous, mostly water soluble fiber. The objective of the study was to evaluate the safety and effectiveness of psyllium husk fiber used adjunctively to a traditional diet for diabetes. After a 2 week dietary stabilization phase, 34 men with type 2 diabetes and mild to moderate hypercholesterolemia (high cholesterol) were
6

randomly assigned to receive 5.1 grams of psyllium or cellulose placebo twice daily for 8 weeks. Serum lipid and glycemic indexes were evaluated biweekly on an outpatient basis and at weeks 0 and 8 in a metabolic ward. The psyllium group showed significant improvement in glucose and lipid values compared with the placebo group. Serum total concentrations were 8.9 percent lower and LDL (low density lipoprotein) cholesterol concentrations were 13.0 percent lower in the psyllium than in the placebo group. All day and postlunch postprandial glucose concentrations were 11 percent and 19.2 percent lower in the psyllium than in the placebo group. Both products were well tolerated, with no serious adverse events related to treatment reported in either group. The authors conclude that the addition of psyllium to a traditional diet for persons with diabetes is safe, is well tolerated, and improves glycemic and lipid control in men with type 2 diabetes and hypercholesterolemia. 1 figure. 3 tables. 45 references.
Federally Funded Research on Hypercholesterolemia The U.S. Government supports a variety of research studies relating to hypercholesterolemia. These studies are tracked by the Office of Extramural Research at the National Institutes of Health.2 CRISP (Computerized Retrieval of Information on Scientific Projects) is a searchable database of federally funded biomedical research projects conducted at universities, hospitals, and other institutions. Search the CRISP Web site at http://crisp.cit.nih.gov/crisp/crisp_query.generate_screen. You will have the option to perform targeted searches by various criteria, including geography, date, and topics related to hypercholesterolemia. For most of the studies, the agencies reporting into CRISP provide summaries or abstracts. As opposed to clinical trial research using patients, many federally funded studies use animals or simulated models to explore hypercholesterolemia. The following is typical of the type of information found when searching the CRISP database for hypercholesterolemia: •

Independent of the effects of the RAS on blood pressure, activation of this system has been identified as a risk factor for the development of ischemic heart disease. Although multiple mechanisms may be responsible for this association, we have focused on the effects of the RAS on the plasminogen activator system, which serves as one of the major endogenous defense mechanisms against intravascular thrombosis and also plays an important role in vascular and tissue remodeling.

of this proposal is that a major component of the vascular toxicity brought on by activation of the RAS is derived from the deleterious effects of angiotensin on fibrinolytic balance. A multifaceted research strategy involving in vitro and in vivo experiments is described to test this hypothesis. The specific aims of this proposal are the following: 1) to test the hypothesis that angiotensin land bradykinin modulate fundamental peripheral circadian oscillating mechanisms that regulate PAl-1 production in vitro; 2) to characterize the role of angiotensin and the All receptor in promoting PAl-1 expression in response to chronic nitric oxide synthase inhibition; and 3) to study the effects of angiotensin II alone and in combination with hypercholesterolemia on the development of coronary thrombosis in transgenic mice that over express a stable form of human PAl-1. It is anticipated that these studies will generate important new information regarding the interactions of the RAS, the vascular endothelium, and fibrinolysis. Furthermore, this project may contribute to our understanding of the regulation of two systems that play vital roles in cardiovascular homeostasis, and thus may improve our abililty to prevent and treat atherothrombotic cardiovascular disease.

Project Title: ANTIOXIDANT FUNCTIONS OF LIPOIC ACID Principal Investigator & Institution: May, James M.; Associate Professor; Medicine; Vanderbilt University 3319 West End Ave. Nashville, Tn 372036917 Timing: Fiscal Year 2003; Project Start 15-JUL-2003; Project End 31-MAR-2005 Summary: (provided by applicant): Lipoic acid has been promoted as an antioxidant effective in a variety of conditions in which there is oxidant damage to the vascular bed, including diabetes mellitus and atherosclerosis. An early manifestation of such damage is dysfunction of the vascular endothelium due to deficient generation or excessive destruction of nitric oxide. Whether lipoic acid can spare nitric oxide and thus lessen endothelial dysfunction is an unanswered question with important clinical implications. We have shown that cultured human endothelial cells take up lipoic acid and reduce it to dihydrolipoic acid. The latter protects the cells in a concentration dependent manner against both internal and external oxidant stresses, and this is associated with an increase in nitric oxide generation by the cells. In this proposal we seek to confirm these novel results, to clarify the mechanism by which they occur, and to determine whether they might be relevant to clinical atherosclerosis. In the first aim we will assess the antioxidant efficacy of lipoic acid in endothelial cells in culture. Oxidant stress will be initiated by agents with biological relevance for the cells, including H202 and minimally oxidized human low density lipoprotein (LDL). Cell protection by lipoic acid will be assessed using a fluorescence-based assay of intracellular oxidant stress, by measuring lipid peroxidation as F2-isoprostanes, and by assay of cellular antioxidants. In the second aim, we will determine whether and how these antioxidant effects of lipoic acid can explain its ability to enhance endothelial nitric oxide generation. We will focus on whether intracellular dihydrolipoic acid acts directly or through glutathione, whether it is synergistic with ascorbic acid, and whether it prevents or reverses impaired nitric oxide generation due to oxidized LDL. Showing that lipoic acid enhances endothelial nitric oxide generation and action will form the basis for a small double-blind, placebocontrolled clinical trial of its ability to reverse nitric oxide-dependent endothelial dysfunction (aim 3). Subjects with increased oxidant stress due to hypercholesterolemia will be studied before and after taking lipoic acid or placebo for 8 weeks with regard to changes in plasma and urinary F2-isoprostanes and flow-mediated brachial artery

dilation. Despite the widespread use of lipoic acid, these studies are necessary to establish the biological basis and rationale for the clinical use of the agent. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: APO A-1 STRUCTURAL MUTATION AND ATHEROSCLEROSIS Principal Investigator & Institution: Sorci-Thomas, Mary G.; Professor, Department of Pathology; Pathology; Wake Forest University Health Sciences Winston-Salem, Nc 27157 Timing: Fiscal Year 2002; Project Start 15-SEP-2000; Project End 31-JUL-2004 Summary: The incidence of premature coronary atherosclerosis in the human population is highly correlated to decreased concentrations of plasma high density lipoproteins (HDL) and its major apoprotein, apolipoprotein A-I (apo A-I). Transgenic and knockout mouse studies have shown that circulating HDL apo A-I primarily plays a "protective function" in response to high levels of atherogenic lipoproteins through its ability to accept, organize and transport cholesterol out of the artery to the liver for uptake and excretion into bile. This "reverse cholesterol transport pathway" is highly dependent upon apo A-I's ester conversion in the plasma. Blockage or reduction in apo A-I's ability to carry out this function can lead to reduced reverse cholesterol transport and inefficient removal of peripheral tissue cholesterol. Data from the applicants' laboratory show that structural alterations in the conformation of plasma apo A-I can have a more profound effect on HDL apo A-I formation and maturation than merely the absence of native apo A-I alone. Their studies show that LCAT activation and thus, plasma cholesterol esterification is inhibited by the presence of a mutant form of apo A-I in plasma. The mutant apo A-I does this by inhibiting plasma cholesterol esterification even in plasma containing native or wild type apo A-I. Thus, they propose to investigate the molecular and cellular basis for the severe disruption in HDL metabolism resulting from the hepatic expression of the mutant human apo A-I, termed 6 apo A-I. This mutant of apo A-I lacks repeat 6, a single proline punctuated 22-mer and has been shown to have a similar plasma lipoprotein phenotype to a known human apo A-I mutation, called apo A-I. In a newly created transgenic mouse model, designated Tg6 apo A-I the applicants propose to conduct dietary-cholesterol feeding studies to determine if mutant apo A-I protects against atherosclerosis in mice with hypercholesterolemia. They also plan to elucidate the molecular and cellular basis for 6 apo A-I's disruption of HDL apo A-I metabolism. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: APO B TRANSLOCATION AND DEGRADATION Principal Investigator & Institution: Davis, Roger A.; Professor; Biology; San Diego State University 5250 Campanile Dr San Diego, Ca 92182 Timing: Fiscal Year 2004; Project Start 01-SEP-1994; Project End 31-MAY-2008 Summary: (provided by applicant): Hepatic production of apo B-containing lipoproteins plays an integral role in lipid metabolism. Imbalances of the production of apo Bcontaining lipoproteins or their removal by the liver are associated with several diseases including atherosclerosis, obesity and diabetes. Data obtained using cultured hepatocytes and genetically altered mice have led us to hypothesize that hepatic secretion of apo B containing lipoproteins is regulated post-transcriptionally. During its translation, apo B has two metabolic fates: translocation into the lumen of the endoplasmic reticulum (ER) during the addition of lipid to form a lipoprotein particle or degradation by an ubiquitin-dependent proteasome pathway. Microsomal triglyceride transfer protein (MTP) and the supply of glycerolipids (phospholipids and triglycerides)
Studies

play an essential role in mediating apo B translocation and assembly into a lipoprotein particle. Based on new and intriguing insights gained during the previous funding period, we will direct our efforts to the following Specific Aims: Specific Aim 1: To define how COUP-TFII interacts with a conserved DR1 site in the MTP promoter and alters gene transcription in rat hepatoma cells and in vivo in the livers of mice. Specific Aim 2: To examine the role of ubiquitin-dependent proteasome degradation in regulating the metabolic fate of apo B in vivo in the livers of mice. Specific Aim 3: To examine the mechanism through which genetic deletion of Txnip alters the flow of carbon units into lipids and secretion of apo B-containing lipoproteins. Clearly, MTPmediated translocation and lipid transfer is an effective target for ameliorating one of the most severe forms of hypercholesterolemia (for which most other drugs [e.g. statins] are ineffective; i.e., homozygous familial hypercholesterolemia). We are confident that our proposed studies will provide new insights that will add further proof to the feasibility and advance the therapeutic potential of controlling the apo B processing pathway.

Project Title: APOJ/CLUSTERIN:A PROTECTIVE PROTEIN IN VASCULAR BIOLOGY Principal Investigator & Institution: Granholm, Norman A.; Pathology and Lab Medicine; University of Cincinnati 2624 Clifton Ave Cincinnati, Oh 45221 Timing: Fiscal Year 2002; Project Start 01-AUG-2002; Project End 31-JUL-2006 Summary: (provided by applicant): Vascular reocclusion remains a significant complication of stent placement: vascular reocclusion occurs in 30-50% of subjects within 1 year of vascular surgery. In-stent restenosis is due primarily to neointima hyperplasia of smooth muscle cells. Thus, understanding the mechanism(s) and biochemical participants in neointima hyperplasia will optimize the design of intervention protocols that reduce the risk of restenosis after vascular surgery. Our Preliminary Results suggest that apolipoprotein (apo) J / clusterin may be an important regulator in determining the vascular response to injury and the development of the neointima lesion. With genetically defined mice as the model, our results show that apoJ expression is induced in response to mechanical injury of the carotid artery. Importantly, apoJ(-/-) mice developed a more severe neointima lesion 2 wk after arterial injury in comparison to wild type mice. Moreover, additional Preliminary Results demonstrate that apoJ(-/-) mice develop increased hypercholesterolemia compared to apoJ wild type mice fed the same cholesterol enriched atherogenic diet. This hypercholesterolemia is associated with an altered distribution of apoE among lipoprotein particles. Therefore, the current study uses the in vivo mouse model to test the hypothesis that apoJ has a direct vascular protective function in vivo by modulating one or more of the cardinal events that contribute to vascular occlusive disease. Specific Aim 1 contains three parts. First, the sequence of events from the time of vascular injury to the time of neointima formation in wild type and apoJ(-/-) mice is compared. The time when differences in vascular pathology are observed is correlated with the temporal expression of apoJ in wild type mice. With these data as a guide, the second part performs gene expression profiling studies to determine the biologic and functional pathways that are modulated by apoJ in the vascular response to injury. The third part uses apoJ-tg mice and adenovirus mediated apoJ gene transfer directly to the vessel wall to test the corollary hypothesis that increased apoJ expression is a viable tactic to limit neointirna hyperplasia. Specific Aim 2 tests the hypothesis that apoJ deficiency exacerbates diet induced hypercholesterolemia by decreasing lipoprotein catabolism

Hypercholesterolemia
via alteration of apoE distribution among lipoproteins. We will characterize the metabolism of VLDL particles in apoJ wild type and apoJ(-/-) mice: quantify catabolism, quantify lipoprotein synthesis and secretion, and quantify transter of apoE from HDL to VLDL. In Specific Aim 3 wild type, apoJ(-/-), and apoJ-tg mice are fed a cholesterol enriched atherogenic diet to test the hypothesis that apoJ is protective, also, against progressive atherosclerosis. Taken together, these studies will identify novel functions of apoJ as well as contribute to our better understanding of the pathogenic events in the vascular response to injury.

Project Title: ARTHEROSCLEROSIS IN INSULIN-RESISTANT, HYPERLIPIDEMIC P* Principal Investigator & Institution: Clemmons, David R.; Professor of Medicine; Medicine; University of North Carolina Chapel Hill Aob 104 Airport Drive Cb#1350 Chapel Hill, Nc 27599 Timing: Fiscal Year 2002; Project Start 30-SEP-2001; Project End 31-AUG-2006 Summary: (provided by applicant): It is unknown why patients with type II insulin resistant (IR) diabetes mellitus have an increased incidence of atherosclerosis when compared to non-diabetics. Our goal is to develop porcine models of IR and a mixed model of IR plus familial hypercholesterolemia that will be useful in studies to define the role of IR in atherosclerosis. The pigs will be used to determine if the presence of IR causes an increased burden of atherosclerosis compared to control animals without IR and to determine if markers of atherosclerosis that are present in these animals will correlate with disease progression in IR animals. Two unique strains of pigs will be used, one from Chapel Hill (CH) with increased total body fat and a second with familial hypercholesterolemia (FH) that are lean. Both the CH and FH strains have subpopulations with and without increased insulin resistance (IR). In Aim I, CH-IR and FH-IR pigs will be bred for increased severity of IR. In Aim II, the effect of IR on the extent of coronary, aortic, and carotid artery atherosclerosis and the changes in serum and tissue markers of atherosclerosis will be determined in CH-IR pigs and compared to CH pigs without IR, both groups being fed a high fat atherogenic diet. A second study will compare these same variables in FH-IR and FH-nonIR pigs fed normal (low fat) pig chow. Intravascular ultrasound (IVUS) will be used during the study to monitor disease progression in vivo. Both IVUS and morphometry of fixed vessels will be used to measure atherosclerosis at termination. In Aim III, insulin like growth factor-I (IGF-1) will be given to the CH-IR pigs to reduce IR, and the pigs will be fed a high fat atherogenic diet. The extent of atherosclerosis and the changes in markers in these IGF-I treated pigs will be compared to controls. In Aim IV, the FH-IR pigs will be fed normal (low fat) pig chow and an aVb3 inhibitor that we have shown reduces atherosclerosis in non-IR pigs and its effect on lesion development determined. Our overall objective is to develop a useful, relevant, available model of IR and atherosclerosis that can be used to identify mechanisms that lead to accelerated atherosclerosis in insulin resistant humans and to develop and test potential new treatment strategies.

Summary: (provided by applicant): Although cerebral ischemia and stroke commonly occur in patients with atherosclerosis, the specific effects of atherosclerotic vascular abnormalities are not reflected in most animal models of stroke. This proposal addresses the effects of atherosclerosis and endothelial dysfunction on cerebrovascular function, reactivity, and response to ischemia, using Western diet-fed apoE knockout mice as an animal model. We have found that apoE knockout mice show decreased resting cerebral blood flow, impaired response to whisker stimulation, and impaired autoregulation, while the response to hypercapnia is relatively preserved. In addition, apoE knockout mice have substantially larger infarcts after middle cerebral artery occlusion than do wild-type mice. We propose four specific aims: Aim 1 tests the hypothesis that hypercholesterolemia and endothelial dysfunction alter cerebrovascular anatomy, physiology (hypercapnia, whisker stimulation, and autoregulation), and pharmacology (pial arteriolar response in cranial window studies) of apoE knockout mice. Aim 2 examines the effects of atherosclerosis and endothelial dysfunction on the response to focal ischemia. We will use high-resolution laser speckle imaging to generate real-time maps of temporal and spatial pattern of cerebral blood flow, and quantitate effects on leukocyte-endothelial cell interactions. Aim 3 tests the hypothesis that superoxide generation is an important mediator of endothelial dysfunction. We will use chemiluminescence detection in endothelial cells, and dihydroethidium staining in sections and in vivo. We will also test the effects of superoxide scavengers on cerebral vascular reactivity (Aim 1) and effects on ischemia (Aim 2). Aim 4 tests whether genetic or pharmacologic interventions directed at augmenting endothelial NO production will restore cerebrovascular reactivity (Aim 1), and ameliorate the response to ischemia (Aim 2). Together, these experiments outline how atherosclerosis and endothelial dysfunction affect the cerebrovasculature, and whether pathophysiologic mechanisms operative in the peripheral circulation also apply to the cerebrovasculature. They also provide proof of principle for approaches that directly target cerebral vascular dysfunction for the treatment and prevention of stroke.

Project Title: B VITAMIN ATHEROSCLEROSIS INTERVENTION TRAIL Principal Investigator & Institution: Hodis, Howard N.; Associate Professor; Medicine; University of Southern California 2250 Alcazar Street, Csc-219 Los Angeles, Ca 90033 Timing: Fiscal Year 2002; Project Start 20-SEP-2000; Project End 31-AUG-2005 Summary: (adapted from the application): Although primary prevention strategies have focused on key modifiable risk factors for development and progression of atherosclerosis, such as hypercholesterolemia, coronary heart disease (CHD) remains the leading cause of death in the United States. Many individuals who present with clinical sequelae of atherosclerosis do not have identifiable conventional risk factors for CHD. Epidemiological studies indicate a strong association of plasma tHcy levels with atherosclerosis from childhood to the elderly. A large number of studies have shown plasma tHcy levels to be an independent risk factor for CHD that is easily modifiable with the B-vitamins, folic acid, vitamin B12, and vitamin B6. Plasma tHcy levels rise 25 % after 50 years of age and may partially account for the age-related risk for CHD. The rise in plasma tHcy levels parallel the age-related decrease in serum levels of folate, vitamin B12, and vitamin B6. Elevated they levels result even with these vitamin levels in the normal to low-normal range. Elderly individuals seem to be most susceptible to development of subclinical vitamin deficiencies since dietary intake of these B-vitamins is approximately 50% the Daily Value after 50 years of age. Low serum folate and vitamin B6 levels are significantly associated with CHD risk. Therefore, low B-vitamin
12
Hypercholesterolemia
status and elevated plasma tHcy levels are important risk factors for atherosclerosis. Evidence, including data from the investigator's laboratory suggests that B-vitamin supplementation can reduce the progression of subclinical atherosclerosis in healthy individuals. Therefore, the investigators propose a multisite, randomized, double-blind, placebo-controlled, 2.5-year, arterial imaging clinical trial with folic acid 5 mg, vitamin B12 2 0.4 mg, and vitamin B6 50 mg versus placebo in healthy men and women >40 years old with LDL-C >130 mg/dL and plasma tHcy >8.5/micromol/L. They will target a cohort of 50% elderly (2-60 years old), 50 % women and 50 % minority subjects. The impact of B-vitamins on the progression of subclinical atherosclerosis will be noninvasively quantitated across several vascular beds with computer image processed B-mode ultrasonograms of carotid artery intima-media thickness and EBCT of the coronary arteries and abdominal aorta. B-vitamin supplementation may provide a promising approach for reducing the progression of atherosclerosis since it is natural, inexpensive, highly tolerable, and safe.

Project Title: BLOCKING INTIMAL HYPERPLASIA FOLLOWING VASCULAR TRAUMA Principal Investigator & Institution: Tzeng, Edith; Assistant Professor of Surgery; Surgery; University of Pittsburgh at Pittsburgh 350 Thackeray Hall Pittsburgh, Pa 15260 Timing: Fiscal Year 2002; Project Start 01-APR-1997; Project End 31-MAR-2005 Summary: Atherosclerotic vascular disease is the leading cause of morbidity and mortality in the United States. Conventional treatments such as angioplasty and bypass procedures are limited in success by the development of intimal hyperplasia (IH). Over the last decade, gene therapy approaches to treating IH have been developed. We propose that one of the best candidate genes for the prevention of IH is the inducible nitric oxide synthase (iNOS) gene. iNOS produces NO which can inhibit smooth muscle cell (SMC) proliferation, promote endothelial cell (EC) regrowth, inhibit platelet and leukocyte adhesion, and promote vasodilation. These properties would be advantageous in treating IH. We used adenoviral mediated iNOS gene transfer in animal models of IH and showed dramatic reductions in IH using very low viral titers. The predominant actions of NO appear to be directed at SMC antiproliferation and EC growth. The efficacy of iNOS gene transfer has fueled an effort to develop this therapy for clinical applications. In this proposal, we will pursue three interrelated aims to further evaluate iNOS gene transfer. AIM 1: To determine the optimal conditions for therapeutic NOS gene transfer for the prevention of vascular injury induced IH. We will evaluate the impact of arginine and cofactor limitations on the efficacy of iNOS gene transfer. In addition, we will perform direct comparisons between the different NOS isoforms to see if any is NOS more efficacious. We will evaluate modified adenoviral vectors that target vascular cells for improving NOS gene delivery. AIM II: To evaluate the consequences of NOS gene therapy in a pi, model of atherosclerosis. Human vascular disease occurs in the setting of atherosclerosis. Therefore, this AIM will focus on studying the impact of hypercholesterolemia and atherosclerosis on iNOS gene transfer efficiency and efficacy. We will also determine if a longer duration of NO production will be required in the setting of atherosclerosis to inhibit IH by a recombinant adeno-associated virus. AIM III: To further characterize the molecular mechanisms of NO- mediated vasoprotection. In this AIM, we will characterize the mechanisms by which NO inhibits SMC proliferation and promotes EC growth, focusing on the role of G-proteins, mitogen-activated protein kinase pathways, and cyclooxygenase-2. At the completion of our studies, we will have the necessary

Project Title: CATABOLISM AND EXCRETION OF CHOLESTEROL AND BILE ACIDS Principal Investigator & Institution: Loose-Mitchell, David S.; Integrative Biology and Pharmacology; University of Texas Hlth Sci Ctr Houston Box 20036 Houston, Tx 77225 Timing: Fiscal Year 2002; Project Start 15-SEP-2000; Project End 31-AUG-2003 Summary: The goal of this proposal is to determine how two key pathways of bile acid biosynthesis are regulated by dietary cholesterol and to determine the mechanisms regulating the apical Na+ -dependent bile-acid transport protein (ASBP) in the ileum. This proposal combines approaches and animal models that have not been combined before to test some basic hypotheses regarding the metabolism and excretion of cholesterol. The proposal has the following goals: 1). To test the hypothesis that the two pathways of bile acid synthesis, the cholesterol 7alpha-hydroxylase pathway and the sterol 27-hydroxylase pathway, are regulated independently, and patterns of regulation depend on cholesterol responsiveness. This will be tested by three different approaches and will take advantage of a unique hypercholesterolemia-resistant rabbit developed at the University of Texas. The applicant proposes a longitudinal study using deuterated 7alpha hydroxycholesterol and 27-hydroxylated cholesterol as bile acid precursors. These studies will precisely measure rates of bile acid synthesis in vivo as animals are fed a hypercholesterolemic and then a hypocholesterolemic diet. The second component of this specific aim will assess rates of bile acid synthesis by the two pathways in an animal with a total bile acid diversion. The third component of this specific aim is directed a elucidating the mechanism through which these two pathways are regulated. The applicant will examine both steady-state rates of mRNA and use a novel transcription assay to assess how altered rates of enzyme biosynthesis is achieved in vivo. 2). To test the hypothesis that expression of ASBP is regulated by both transcriptional and posttranscriptional mechanisms. This will be tested both in normal and in the hypercholesterolemia-resistant rabbits and the applicant will examine levels in the activity, mRNA, and transcription of the transporter and determine if changes in mRNA are reflected in levels of ASBP protein and localization. In addition, the applicant will determine the functional consequences of ASBP allele found in the hypercholesterolemic rabbit. These studies will make a significant contribution to the understanding of the only routes by which significant cholesterol is removed from the body. In this respect the applicant anticipates that the results will impact upon the treatment of cardiovascular diseases well as having significance for fundamental biological questions of the control of cholesterol homeostasis.

Principal Investigator & Institution: Heistad, Donald D.; Director; University of Iowa Iowa City, Ia 52242 Timing: Fiscal Year 2002; Project Start 01-JUN-2002; Project End 31-MAY-2007 Summary: Diabetes is a major risk factor for stroke. Clinical evidence indicates that diabetes accelerates development of atherosclerosis, but mechanisms that account for this interaction are not clear. The investigators speculate that hypercholesterolemia may
14
Hypercholesterolemia
exaggerate endothelial dysfunction through increased superoxide in vessels during hyperglycemia. The goal of this project is to examine pathophysiological interactions between hyperglycemia and hypercholesterolemia in carotid and intracranial cerebral arteries. It is likely that hyperglycemia will accelerate development of atherosclerosis in the carotid artery, but because diabetes is also a disease of small vessels, it will be particularly important to examine effects in the cerebral microcirculation. There are 3 major aims. First, studies are proposed to test the hypothesis that hypercholesterolemia augments generation of superoxide and endothelial dysfunction in carotid and cerebral arteries during hyperglycemia. Second, studies are planned to identify the contribution of endothelium, vascular muscle, and adventitia to superoxide in carotid and cerebral arteries during hyperglycemia and hypercholesterolemia. Third, studies are proposed to elucidate enzymatic mechanisms that account for cerebral vascular dysfunction. The investigators propose to test the hypothesis that vascular NADPH oxidase contributes to increased levels of superoxide and, therefore, vascular dysfunction during diabetes and hypercholesterolemia. Studies are planned in carotid and basilar artery of rabbits and mice in vitro, and in carotid artery and cerebral vessels in vivo. Endothelial vasomotor function will be examined, and superoxide in vessels will be studied with lucigenin chemiluminescence, and with laser confocal microscopy. Levels of superoxide dismutase (SOD) and superoxide in the vessel wall will be altered by pharmacological approaches, adenoviral mediated gene transfer of CuZnSOD to different layers of the vessel wall, with a newly made CuZnSOD transgenic mouse targeted to vascular smooth muscle, and with mice lacking functional NADPH oxidase. These studies may provide important insight about mechanisms which produce accelerated cerebral vascular dysfunction during diabetes and hypercholesterolemia.

The endoplasmic reticulum (ER) is an organelle found in all higher organisms, whose central role in cell function is to mediate protein synthesis. Humans afflicted with abnormal protein processing in the ER and a related organelle, the Golgi body, suffer from devastating developmental abnormalities and comprise a broad category of disease known as Congenital Disorders of Glycosylation (CDGs). The key aspect of protein processing in the ER and Golgi is the addition of sugars to newly synthesized proteins, called glycosylation. This proposal seeks to characterize fundamental aspects of protein glycosylation, specifically how abnormal glycosylation influences the generation of signals within a cell. These signals are generated as a result of abnormal protein synthesis, which results in ER stress. The activation of ER stress can result in cell suicide (apoptosis), adaptation to the stress, growth arrest, or stimulation of localized inflammation. Our long-term goals focus upon how cells activate apoptosis following ER stress. This proposed project will allow characterization of the molecules that carry this stress signal, and examine how this cell suicide is executed. The improper processing of proteins in the ER and Golgi causes mutations in a variety of genes, and the type of disease that results from such mutations depends upon the identity of the mutated protein. Cystic fibrosis patients suffer lung degeneration that is the result of ER stress-activated signals as a membrane protein is

improperly glycosylated, and one type of inherited hypercholesterolemia (high cholesterol) is the result of ER-associated processing deficiencies of a signal receptor. The characterization of ER stress and its signaling mechanisms will offer vital insight into the cell biology of stressed cells, and will be valuable to our understanding of diseases that result from abnormal ER function/processing.

Project Title: CHOLESTEROL AND AMYLOIDOGENESIS Principal Investigator & Institution: Pappolla, Miguel A.; Professor; Pathology; University of South Alabama Mobile, Al 366880002 Timing: Fiscal Year 2003; Project Start 01-JUN-2003; Project End 31-JAN-2004 Summary: (provided by applicant): Recent studies have shown that increased levels of Ab peptides are among the earliest detectable abnormalities in Alzheimer's disease and may mediate a chain of downstream events leading to neuronal degeneration and cognitive decline. There is increasing evidence from clinical, epidemiological and laboratory studies that cholesterol plays a role in the pathogenesis of Alzheimer's disease. This body of evidence includes in vitro studies indicating that cellular cholesterol levels modulate Ab production and the enzymatic processing of APP, animal studies demonstrating that cholesterol levels modulate Ab accumulation in the brain (preliminary data) and several observational, clinical studies suggesting that the prevalence and incidence of probable Alzheimer's disease was significantly lower in patients taking cholesterol-lowering drugs. Taken together the studies support the hypothesis that Alzheimer's disease may be a disease in which cholesterol homeostasis is altered and that cholesterol may participate in a chain of events that modulate the disease neuropathology. The application proposes to test the following hypotheses: 1that in the human brain increased cholesterol content contributes to amyloid accumulation by changing APP processing in a more amyloidogenic manner. 2-that there are correlative interactions between levels of apoE expression, cholesterolemia and amyloid pathology. 3-that certain apoE promoter polymorphisms act in concert with cholesterol levels influencing the extent of apoE expression and amyloid accumulation. Preliminary and recently published data from our laboratory suggest that cholesterol content in plasma and brain of Alzheimer's transgenic mice is strongly correlated with rate of development of amyloid pathology and with apoE expression. These hypotheses are amenable to testing as outlined in the corresponding sections of the proposal and their study will advance our understanding of the pathogenesis of Alzheimer's disease.

The program has successfully integrated emer4ging molecular techniques with more traditional physiological approaches to examine mechanisms that regulate structure and function of the cerebral circulation under normal and pathophysiological conditions. This evolution within the program continues with this renewal as new approaches and investigators continue to be incorporated. The program has several well-defined themes: First, protective mechanisms [nitric oxide, superoxide dismutase (SOD)], and
16
Hypercholesterolemia
peroxisome proliferator activated receptor (PPAR) in cerebral blood vessels. Second, sources of superoxide within the vessel wall [NAD(P)H oxidase and cyclooxygenase (COX)] and the role of the major cell types-endothelium, smooth muscle, and adventita. Third, pathophysiology and risk factors for cerebral vascular disease and stroke. Modern molecular and mechanistic approaches are used to examine effects of chronic hypertension, diabetes, hypercholesterolemia, hyperhomocysteinemia, and inflammation on cerebral vascular structure and function. The Program has several strengths. First, the investigators have a long, productive history of studies of cerebral circulation under physiological and pathophysiological conditions. Second, strong new investigators with key expertise have been integrated into the program. Third, the investigators use diverse, cutting edge approaches altered mice and viral mediated gene transfer, were successfully incorporated during the last funding period and continue to be used heavily. Fourth, the investigators are leaders in several areas of study of the cerebral circulation (endothelial cell biology, nitric oxide, potassium channels, vascular structure) as well as leaders in studies of the impact of cardiovascular risk factors on cerebral vascular biology. The program consists of four projects supported by two core facilities: Administration and Transgenic Animal Core. This integrated, multidisciplinary approach is intended to facilitate, rapid progress, and more penetrating insight, in understanding mechanisms that regulate cerebral vascular structure and function.

Project Title: CORONARY VASA VASORUM - ROLE OF 3D BRANCHING GEOMETRY Principal Investigator & Institution: Ritman, Erik L.; Professor; Mayo Clinic Coll of Medicine, Rochester 200 1St St Sw Rochester, Mn 55905 Timing: Fiscal Year 2002; Project Start 01-APR-2001; Project End 31-MAR-2005 Summary: (Verbatim from the Applicant's Abstract): This resubmission consists of a chronological sequence of three overlapping aims which test the overall hypothesis that the vasa vasorum play an important role in the initiation of coronary atherogenesis (i.e., prior to cellular invasion and/or proliferation) by virtue of disturbed solute transport via the vasa vasorum This, in turn, is due to the perfusion pressure in their distal vasa vasorum lumens being less than the compression in the arterial wall. Our approach is to quantitatively describe detailed branching geometry and solute transport of the vasa vasorum of coronary arteries, primarily by use of micro-CT-based imaging methods. This will involve analysis of coronary arteries of normal pigs, a porcine (diet-induced) model of hypercholesterolemia and a porcine (renal artery stent) model of arterial hypertension (both being risk factors for atherogenesis). AIM I is for the initial development and integration of the various techniques we propose to use throughout the proposal and to establish the normal state. AIM II applies the developments in Aim I to hypercholesterlemic and to hypertensive pigs' coronary artery walls so as to relate the response of the vasa vasorum to these pathological conditions. AIM III builds on Aim II in that we will combine the hypercholesterolemia and hypertension to see if they are linearly additive in effect, as would be predicted by our hypothesis. The primary objective is to relate the transport capacity of vasa vasorum to the spatial density of coronary artery vasa vasorum and the fluid dynamic implications of both the 3D branching geometry of the vasa vasorum and the spatial distribution of compressive stresses within the coronary artenal wall. The significance of this proposal is that if the hypothesis of this study is supported, it should give insight into several puzzling observations. One is that atherosclerosis does not generally form in veins (which have

vasa vasorum) or in small arteries (which have no vasa vasorum). Equally intriguing is the observation that early atherosclerosis does not form in the outer media or adventitia even though vasa vasorum provide a sizable endothelial surface (which presumably also becomes dysfunctional) in the outer media and adventitia. Another observation is that artenes whose adventitia are manipulated and veins, which are subjected to arterial pressure or surgically manipulated, do develop atherosclerosis.

Project Title: CUTANEOUS GENE TRANSFER FOR SYSTEMIC DELIVERY Principal Investigator & Institution: Taichman, Lorne B.; Professor; Oral Biology and Pathology; State University New York Stony Brook Stony Brook, Ny 11794 Timing: Fiscal Year 2002; Project Start 01-MAY-1979; Project End 31-JAN-2005 Summary: ( Investigator's abstract): The goal of this research is to develop a gene-based therapy for metabolic deficiency disorders using cutaneous cells as a vehicle for systemic delivery. New genetic material would be introduced into epidermal keratinocytes and dermal fibroblasts to create a cutaneous source of secreted protein. For example, the hypercholesterolemia and atherosclerosis of type III hyperlipoproteinemia may be ameliorated by creation of a cutaneous source of apolipoprotein E3 (apoE). The question posed here is, can sufficient protein be produced and delivered to the circulation to ameliorate such a disorder? To date, the Principal Investigator has made substantial progress in development of methods for ex vivo and in vivo gene transfer, using retrovirus vectors in analysis of the secretory capacity of fibroblasts and keratinocytes, and in creating culture and animal models for quantitative analysis and efficacy testing. The Principal Investigator has succeeded in transducing keratinocyte stem cells through ex vivo and in vivo approaches and has demonstrated long term (10 month) reporter gene expression in animal models. In this revised application three specific aims are proposed. In Aim 1, studies are proposed to optimize systemic replacement therapy through ex vivo gene transfer. First a system that allows repeated monitoring of secreted protein in the same animal will be developed and then that system will be used to develop predictive in vitro tests, to examine dermal versus epidermal delivery, and to gauge if lymphatic uptake is rate limiting. As proof of principal, two animal models will be used, one involving apoE-deficient mice and the other involving diabetic rats. In Aim 2, the methods for in vivo transduction of mouse skin will be optimized. Specifically the use of lentivirus vectors to transduce slowly cycling stem cells in skin and application of a topical selective agent to augment the number of transduced cells in the tissue will be used. To control transgene expression in vivo, Aim 3 will involve construction of two retroviral vectors, one to permit transgene induction with topically applied inducers and the other to evade potential modulating effects of host cytokines. These studies probe the interface between cutaneous biology and corrective gene transfer and will provide a foundation for future clinical cutaneous gene therapy trials.

Project Title: DETERMINANTS OF CLATHRIN STRUCTURE AND FUNCTION Principal Investigator & Institution: Ybe, Joel A.; Biology; Indiana University Bloomington P.O. Box 1847 Bloomington, in 47402 Timing: Fiscal Year 2003; Project Start 30-SEP-2003; Project End 31-AUG-2008 Summary: (provided by applicant): Clathrin coated vesicles (CCVs) carry out receptormediated endocytosis (RME) at the plasma membrane, where they drive the uptake of
18
Hypercholesterolemia
receptor bound nutrients, hormones and proteins targeted for degradation. Clathrin is shaped like a "three-legged" pinwheel to fit its function of forming honeycomb lattices around transport vesicles. The long-term goal of this proposal is to define and validate productive atomic contacts between lattice-bound clathrin molecules to elucidate the fundamental principles of how clathrin function is regulated in cells. The first specific aim is to determine the crystal structure of the clathrin trimerization domain, where the three filamentous legs meet, to complete the atomic level reconstruction of the entire clathrin molecule. Trimerization domain crystals are highly ordered, diffracting between 1.7-2.3 A at Argonne and at the Advanced Light Source. Selenomethionine crystals have been prepared to solve the phasing problem by MAD analysis, while heavy metal replacement and "cryo-halide" soaking methods are being performed as alternative phasing strategies. The X-ray model of trimerization domain will then be docked into the 21 A cryo-EM image of the clathrin barrel (with Barbara Pearse, Corrine Smith and Alan Roseman) to identify productive molecular contacts between the trimerization domain and segments of other clathrin molecules in the lattice. Revealed interactions will be tested biochemically and validated in living cells. The second aim is to explore how cysteines in the trimerization domain stabilize this structure by using structural information from Aim 1 to design mutants to test specific linkages. The third aim explores whether there is a relationship between the cysteines in the trimerization domain and those in light chain subunit to understand why these two groups of cysteines impact regulation of clathrin assembly. The experimental approach is to determine whether light chains can confer structural stability to trimerization domain constructs weakened by mutations made in Aim 2. The final aim of this proposal is to test the possibility that light chain control of lattice formation might involve the transfer of the light chain EED Ph switch between an "active" and "inactive" position on the proximal domain of clathrin. The approach is to use light chain fragments and molecule mimics to ferret out these putative sites and to use X-ray crystallography to try to capture the orientation of light chain fragments bound to the proximal region. Understanding the structural basis for clathrin function is central to defining the role of RME malfunction in hypercholesterolemia and heart disease, as well as understanding the mechanism of virus infection.

The pathogenesis of atherosclerosis and CHD is thought to be initiated by endothelial dysfunction or injury. Factors that contribute to oxidative stress such as elevated cholesterol-rich low density and very low-density lipoproteins (LDL and VLDL) result in endothelial dysfunction. The long term goal of this proposal is to develop dietary interventions for the prevention and treatment of endothelial dysfunction in children and adolescents who are at high risk for premature CHD due to the genetic lipid disorders of familial hypercholesterolemia (FH) or familial combined hyperlipidemia (FCH). This experimental, randomized, double blind crossover, placebocontrolled clinical trial will include 96 hyperlipidemic children and adolescents aged 10 to 18 years who will receive dietary supplements and an intensive dietary educational program. The following hypothesis will be evaluated: Specific nutrients in the diet will

have direct beneficial vascular effects and/or indirect effects on lipoprotein composition which will in turn decrease the oxidation of LDL and the level of vascular oxidative stress, thereby improving endothelial function. The primary specific aims are: 1) to determine whether a National Cholesterol Education Program (NCEP) Step II diet alone or together with one of four putative vasculoprotective supplements (Vitamins C & E, w-3 fatty acids, L-arginine, folic acid) will improve endothelial function in children and adolescents with FH and FCH, and 2) to evaluate the effects of these supplements on plasma lipoprotein profiles, LDL composition, lipoprotein-associated antioxidant enzymes (paraoxonase and platelet activating factor acetyl hydrolase), indices of oxidative stress (oxidized LDL, 8-hydroxy-2'-deoxyguanosine), immune function (inflammatory cytokines, plasma adhesion molecules), and blood pressure. Vascular reactivity, a sensitive indicator of endothelial function, will be measured noninvasively using high-resolution external vascular ultrasound of the brachial artery. The secondary aims are: 1) to examine children and adolescents psychological well being, beliefs and feelings about their cardiovascular status and its relation to health outcomes, and 2) To explore their practices and health risk behaviors specifically in the area of dietary adherence. These studies will provide important insight into the mechanism of endothelial dysfunction and should serve to identify potential treatments for pediatric hyperlipidemia. Preventive nursing strategies aimed at early detection of endothelial dysfunction and dietary modification may restore endothelial function in children and adolescents at high risk for CHD.

Project Title: DYNAMICS OF FLOW-DEPENDENT ARTERIAL PERMEABILITY Principal Investigator & Institution: Friedman, Morton H.; Professor; Biomedical Engineering; Duke University Durham, Nc 27710 Timing: Fiscal Year 2002; Project Start 01-APR-1994; Project End 31-MAR-2004 Summary: The overall objective of this research is to understand the factors affecting the transendothelial entry of macromolecules into the arterial wall, and particularly the mediation of this process by local hemodynamics. The interest in macromolecular transport is prompted by its importance in the genesis and development of artherosclerosis. The mediation of arterial uptake by hemodynamic factors is of particular interest because the distribution of atherosclerotic lesions suggests that hemodynamic factors may be involved in the localization of the disease; furthermore, there is evidence that hemodynamic stress can influence endothelial permeability. A primary hypothesis of this research is that an important fraction of the transendothelial flux occurs during increases in permeability prompted by changes in flow; accordingly, particular emphasis is placed on the dynamic response of the barrier function of the endothelial lining to changes in the hemodynamic environment. The research objectives are addressed through a unique combination of animal experiments, computer simulation and cell and molecular biology. The spatial variation of the albumin permeability in the eternal iliac arteries of swine, either at baseline or subsequent to interventions that alter flow, will be obtained using photographic densitometry of Evans Blue dye to measure albumin uptake. The alterations in flow will be produced by reversible, adjustable femoral arteriovenous shunts. The distribution of wall shear stress, and of the changes in stress caused by manipulating the shunt, in the iliac vessels will be obtained from validated fluid dynamic computations in regions derived from injection casts of the arteries and the proximal vasculature; the dependence of albumin uptake on hemodynamic stress, and alterations in stress, will be assessed and modeled. In a separate set of animals, casting material will not be injected, and tissue from the region

Of particular interest are properties that mediate the redox state of the cell, the integrity of the cytoskeleton, and its junctions with neighboring cells and adhesion to the substratum. The effects of hypercholesterolemia on vascular permeability and its dynamic response to changes in flow will be examined as well, to determine whether high lipid levels potential the effects of flow changes on vascular uptake.

Project Title: EFFECT OF LIPIDS ON VASCULAR GRAFT HEALING Principal Investigator & Institution: Graham, Linda M.; Professor; Cleveland Clinic Foundation 9500 Euclid Ave Cleveland, Oh 44195 Timing: Fiscal Year 2002; Project Start 01-AUG-2000; Project End 31-JUL-2004 Summary: (Adapted from Applicant's Abstract): Prosthetic grafts are used widely in vascular reconstructive surgery, but their long-term patency is limited, perhaps due to altered cell function caused by oxidized low density lipoprotein (oxLDL). In preliminary studies they have shown that: 1) graft material stimulates monocytic cells to oxidize LDL in vitro, 2) this oxLDL inhibits endothelial cell (EC) migration in vivo. This contributes to the prolonged thrombogenicity and eventual failure of these grafts. The goal of this project is to determine the effect of lipids, especially oxidized lipids, on EC migration on prosthetic grafts. To test their hypothesis, the effect of oxidized lipids on EC migration and the mechanism by which oxLDL inhibits EC migration will be studied. The investigators will first investigate the role of reactive oxygen species (ROS) in oxLDL's inhibition of EC migration. They will characterize the effect of oxLDL on superoxide production by EC, assessing the effect of ROS on EC migration, and determining the ability of antioxidants to restore EC migration in the presence of oxLDL. Since ROS alter membrane fluidity and changes in fluidity affect migration, they will investigate the effect of oxLDL on EC membrane fluidity. They will also evaluate the ability of vitamin E and other antioxidants to prevent changes in membrane fluidity and preserve EC migration. The effect of oxLDL on EC migration on ePTFE graft material in vitro will be studied, and the ability of vitamin E or superoxide dismutase to restore migration determined. Finally, they will study the effect of hypercholesterolemia on EC ingrowth onto prosthetic grafts implanted in rabbits, and assess the ability of vitamin E to preserve endothelial migration. The proposed studies will investigate the role of lipids and lipoproteins, and their oxidatively modified derivatives, in the failure of synthetic vascular grafts to endothelialize. Studies will also address the efficacy of treatment with dietary antioxidants to control lipid oxidation and promote graft healing. This will lead to a better understanding of the role of lipids in the pathophysiology of graft failure. Ultimately, this may lead to methods to promote endothelialization of prosthetic grafts and prolong patency of small-diameter vascular grafts.

circulation, are augmented in response to certain cytokines and/or tissue ischemia, and home to sites of neovascularization. More recently, EPCs have been investigated as therapeutic agents to successfully enhance neovascularization. Just as classical angiogenesis may be impaired in certain pathologic phenotypes, however, ageing, diabetes, hypercholesterolemia, and hyperhomocysteinemia may likewise impair EPC function, including mobilization from the bone marrow and/or incorporation into neovascular foci. Gene transfer of EPCs during ex vivo expansion constitutes a potential means of addressing such putative liabilities in EPC function. Moreover, phenotypic modulation of EPCs during ex vivo expansion constitutes a potential means of addressing such putative liabilities in EPC function. Moreover, phenotypic modulation of EPCs ex vivo may also reduce the number of EPCs required for optimal transplantation post- ex vivo expansion, and thus serve to address a practical limitation of EPC transplantation post-ex vivo expansion, and thus serve to address a practical limitation of EPC transplantation, namely the volume of blood required to extract an optimal number of EPCs for autologous transplantation. The experiments outlined in this Proposal will investigate the thesis that gene transfer can be employed to achieve phenotypic modulation of EPCs. The Proposal has three specific aims. First, we will perform in vitro assays, as well as in vivo experiments in animal models of tissue ischemia, to optimize the methodology and effectiveness for EPC gene transfer of angiogenic growth factors. Second, we will investigate the role of the serine-threonine protein kinase, Akt (also known as protein kinase beta), in the biological activation of EPCs, using gene transfer strategies involved constitutively active and dominant negative forms of Akt. Third, we will investigate the impact of telomerase reverse transcriptase (TERT) gene transfer on EPC function and survival, in vitro and in vivo. We anticipate that the results of these experiments will yield new insights regarding both the fundamental biology as well as therapeutic applications of EPCs for postnatal neovascularization. If we are successful, these results will resolve certain issues sufficiently to permit translation to clinical studies, and provide new questions that will stimulate additional inquiries.

Project Title: ENHANCED LINKAGE MAPS FROM FAMILY-BASED GENETICS STUDIES Principal Investigator & Institution: Matise, Tara C.; Associate Research Professor; Biology; Rutgers the St Univ of Nj New Brunswick Asb Iii New Brunswick, Nj 08901 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-AUG-2004 Summary: (provided by applicant): Meiotic linkage maps are the foundation of both linkage and linkage disequilibrium studies for mapping disease genes. Despite the importance of precise maps, existing genome-wide linkage maps were built using only a small collection of pedigrees, and so have wide confidence intervals surrounding estimates of map distance. Incorrect marker order and map distances can have a profound effect on linkage analyses. Using a sex-averaged map instead of a sex-specific map biases the lod scores upward, markedly increasing the false positive rate. Since it is very costly to follow-up many false-positive results, there is a clear need for more precise and accurate sex-specific genetic maps. Accurate estimates of meiotic map distance cannot be obtained by any means other than by linkage analysis using genotype data. We propose to build improved highly-precise sex-specific linkage maps utilizing thousands of individuals who have previously been genotyped. After filtering out obvious relationship and genotype errors, we will incorporate methods that properly model for genotyping errors. In addition to creating precise maps for the
22
Hypercholesterolemia
scientific community, we also propose to use these genotype data to study how recombination may vary between ethnic groups. The genotypes generated by the NHLBI Mammalian Genotyping Service are precisely the type of data required to produce more accurate maps. These data collections contain over 3,400 pedigrees with more than a 1 00-fold increase in information compared to that contained in the 8 CEPH families that have been used to construct current genome-wide linkage maps. Our new maps will be made publicly available and the genotype data from our study will be accessible by the MAP-0-MAT linkage mapping server. In the future, we anticipate broadening our study to incorporate genotype data from additional genotyping centers such as the Center for Inherited Disease Research (CIDR). The inaccuracies present in current maps can contribute to misleading results, and may be one of the reasons that disappointingly few genes have been definitively identified that contribute to such complex diseases as asthma, cardiovascular disease, hypertension, hypercholesterolemia, diabetes, obesity, and cancer. The more precise maps that we propose to construct will improve the power and value of many ongoing and new disease studies. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: FETAL DETERMINANTS OF ATHEROSCLEROSIS Principal Investigator & Institution: Palinski, Wulf; Professor of Medicine; Medicine; University of California San Diego La Jolla, Ca 920930934 Timing: Fiscal Year 2003; Project Start 01-FEB-2003; Project End 31-JAN-2007 Summary: (provided by applicant): We previously showed that atherogenesis already begins during fetal development and that maternal hypercholesterolemia during pregnancy is associated with enhanced fatty streak formation in fetuses and a much faster progression of atherosclerosis in normocholesterolemic children that could not be explained by conventional risk factors. Although in humans inherited genetic differences are likely to contribute, we hypothesize that maternal hypercholesterolemia per se induces pathogenic events in fetal arteries that determine their later susceptibility to atherosclerosis. We also hypothesize that oxidative stress caused by maternal hypercholesterolemia leads to persistent changes in the expression of genes modulating atherogenesis. An important corollary is that cholesterol lowering and antioxidant interventions in mothers during pregnancy may provide long-lasting benefits to their offspring. Using genetically homogeneous animal models, we recently provided direct evidence for the causal role of maternal hypercholesterolemia and oxidative stress in both enhanced fetal lesion formation and accelerated post-natal atherogenesis. We also provided proof in principle for persistent regulation of gene expression in the arterial wall. We now propose to better define the in utero programming associated with maternal hypercholesterolemia, to identify genes influencing post-natal susceptibility to atherosclerosis, and to investigate whether interventions during pregnancy also decrease the susceptibility in offspring of "normocholesterolemic" mothers. Different levels of maternal hypercholesterolemia and antioxidant protection will be achieved by transferring embryos of LDL receptor deficient (LDLR-/-) mice into treated or untreated C57BL/6, LDLR -/- or apoE -/- mice. Offspring will be subjected to post-natal atherogenic conditions and lesion formation followed over time. Laser-capture microdissection, gene microarray and PCR techniques will be used to determine persistence of gene regulation and its correlation with atherosclerosis, immunocytochemical presence of gene products and measurements of oxidative stress. These studies should yield fundamentally new insights into in utero programming and atherogenic mechanisms, and may establish a novel preventive approach.

Project Title: FLAX: SAFETY & EFFICACY IN REDUCING CARDIOVASCULAR RISK Principal Investigator & Institution: Szapary, Philippe O.; Medicine; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2002; Project Start 26-SEP-2002; Project End 31-MAY-2004 Summary: (provided by applicant): Hypercholesterolemia is an important established risk factor for atherosclerotic cardiovascular disease (ASCVD). The National Cholesterol Education Program (NCEP) has recently estimated that 100 million Americans qualify for treatment of their hypercholesterolemia. Of these Americans, 65 million could be managed with diet and exercise alone, referred to as Therapeutic Lifestyle Changes (TLC) by the most recent NCEP guidelines. The NCEP has already recognized the importance of diet and Complementary Alternative Medicine (CAM) therapies in the management of dyslipidemia by incorporating soluble fiber and plant-based stanol esters as part of TLC. Flaxseed is a unique food as it contains significant amounts of soluble fiber as well as the richest source of both alpha-linolenic acid (ALA) and phytoestrogenic lignans, which have all been implicated in the prevention of ASCVD. Because flaxseed contains these constituents, it may play an important role in TLC in the future, but data is currently lacking. In addition, because lignans can bind to the estrogen receptor and elicit a hormonal response, chronic flaxseed consumption may have undesirable hormonal effects. Thus in this project, we propose to systematically evaluate the safety and efficacy of ground flaxseed ingestion in both men and women with hypercholesterolemia over the short term. This will be done in a single doubleblind, randomized, placebo controlled clinical trial. Because little is known about the metabolic effects of flaxseed in men, randomization will be stratified by gender. The test dose of flaxseed meal will be 40 grams administered in baked products and compared to a matching wheat bran control. The primary endpoints of this study are to evaluate the effects of flaxseed consumption on lipid metabolism and oxidative stress. The primary response variables in terms of lipid metabolism will include low density lipoprotein (LDL-C) cholesterol and post-prandial triglycerides. For the evaluation of oxidant stress, the primary response variable will be urinary isoprostane secretion, the most sensitive marker of in vivo oxidative damage. Secondary variables of interest will include markers of cholesterol metabolism, vascular inflammation, endocrine function, safety and acceptibility. The results from this study will lay the foundation for several lines of research into the clinical and biochemical effects of flaxseed supplementation in modulating cardiovascular risk. Specifically, the data generated from this project will be used as preliminary data to pursue R01 submissions to NCCAM and NHLBI to investigate the long-term effects and mechanisms of action of the various components of flaxseed on lipid metabolism and clinical endpoints in patients at risk for ASCVD.

Project Title: GENES CAUSING SPONTANEOUS OBESITY Principal Investigator & Institution: Warden, Craig H.; Associate Professor; Pediatrics; University of California Davis Sponsored Programs, 118 Everson Hall Davis, Ca 956165200 Timing: Fiscal Year 2002; Project Start 01-JUN-1998; Project End 31-MAY-2003 Summary: The long-term goal of this research is to investigate the mechanisms of spontaneous obesity in mice. Previous work has identified 4 chromosomal regions

Hypercholesterolemia
(mouse chr. 6,7,12,and 15) or loci (QTLs) that contribute to obesity in spontaneously obese BSB mice. BSB mice were produced by a backcross of (Mus spretus x C57BL/6J) F1 x B6. Preliminary data on an available congenic mouse strains confirm that the locus on chr. 7 affects adiposity. The objective of this present proposal is to identify the genes underlying these obesity loci. Congenic mouse strains carrying the spretus chromosomal regions as donor DNA on the B6 background will be created. As co-incident QTLs for obesity, plasma cholesterol and hepatic lipase (HL) activity on mouse chr. 7 were found, the already constructed B6 HL knockout will used to test the hypothesis that alterations of HL activity determine these cholesterol and/obesity loci. BSB backcrosses with the HL KO B6 mouse will yield animals both homozygous and heterozygous for the HL knock-out. QTLs at chromosome 7; will be compared and contrasted in these two groups. The mouse chr. 6,7, and 1 loci include within their 90 percent confidence intervals, respectively, the obese, tubby, and uncoupling protein 2-genes. Molecular and biochemical studies of these candidate genes will be performed to test whether differences are likely to explain the observed effect on the trait. If there are differences in the coding portion of the spretus and B6 leptin, then the biological consequence of the differences will be tested. The chromosome 6 locus was linked to just one of the four fat pads measured in BSB mice. Leptin mRNA levels in the four fat pads will be determined to examine their correlations with plasma leptin and fat pad sizes. They have already found that spretus and B6 UCP2 differ for 2 amino acids, so uncoupling activity of UCP2 from these strains will be examined.

Project Title: GENETIC AND BIOMEDICAL STUDIES OF SITOSTEROLEMIA Principal Investigator & Institution: Patel, Shailendra B.; Professor; Medicine; Medical University of South Carolina P O Box 250854 Charleston, Sc 29425 Timing: Fiscal Year 2002; Project Start 01-FEB-2000; Project End 31-JAN-2004 Summary: Heart disease remains the major cause of death and morbidity in the US. Reduction in the risk factors for heart disease remains a priority for Healthy People 2000. One of these risk factors is cholesterol. Understanding the factors that normally regulate net dietary cholesterol intake may allow us to reduce the impact of this risk factor. One such factor may the gene that is responsible for causing the autosomal recessive disease, sitosterolemia (OMIM 210250). The purpose of this study is to identify, map, and clone and characterize the biology of this gene. This gene is hypothesized to play a key role in regulating the absorption of cholesterol from the diet and its excretion from the body via the bile. Sitosterolemia is characterized by a marked elevation of plant sterols in the blood, resulting in tendon xanthomas, premature coronary artery disease and death. Knowledge of the genetic mechanisms underlying these biological processes may allow us to explore ways to manipulate cholesterol absorption and excretion through the activities of this gene product and thus control plasma cholesterol levels. 27 well-characterized family pedigrees have been assembled, providing considerable power to map and localize of the gene defect. Following the exclusion of a number of candidate genes, a genome-wide scan has been performed. The gene has been mapped to chromosome 2p21, with a maximum lodscore of 4.6. Fine mapping and haplotype analyses has narrowed the sitosterolemia locus to within a region approximately 2 cM in size. Additional families will be recruited and analyzed for evidence of recombination within this region to help further narrow this critical region. Once a suitably narrow region has been defined, cDNAs mapping to this region will be identified and used as candidate genes to allow us to identify the defective gene. The identification of this gene defect will not only allow characterization of the

25
mutations that cause sitosterolemia, but will also provide the basis for in vitro expression studies to define some of this gene's normal functions in sterol absorption and excretion. This knowledge will allow us to test the hypothesis that the normal function of this gene product is to tightly regulate net dietary cholesterol absorption.

Project Title: GENOMIC RESOURCE DEVELOPMENT IN THE LABORATORY OPOSSUM Principal Investigator & Institution: Samollow, Paul B.; Southwest Foundation for Biomedical Res San Antonio, Tx 782450549 Timing: Fiscal Year 2002; Project Start 01-FEB-2001; Project End 31-JAN-2005 Summary: (Adapted from the applicant's abstract): The gray-short-tailed opossum, M. domestica, has been established as a model organism for comparative biomedical research on a broad range of topics that are relevant to human development, physiology, and disease susceptibility. However, a lack of basic information on fundamental genetic characteristics limits its potential for inquiries involving the genetic regulation of normal developmental and physiologic processes, and the influences of genetic variation on health-related physiologic characteristics. To mitigate this situation, a map of the M. domestica genome will be constructed that can be used to detect, map, and ultimately isolate and clone genes that influence normal and abnormal phenotypic variation. The overall objectives are to construct a linkage map of 200 or more polymorphic marker loci, to use physical mapping studies to anchor the linkage map on the physical genome, and to use the map to determine the locations of one or more genes that influence variable responsiveness of dietary cholesterol and fat. The Specific Aims are to: 1) expand the number of anonymous and functional gene markers on the existing, sparsely-filled linkage map through continuing linkage studies utilizing an existing backcross mapping panel; 2) complete a 5 cM linkage map by creating, and utilizing for mapping, a new backcross mapping panel designed to maximize opportunities for the detection and mapping of polymorphisms at functional gene loci; 3) develop a physical map showing the locations and orientations of known linkage groups on M. domestica chromosomes; and 4) detect and map one or more of the genes responsible for highly heritable variation in diet-induced hypercholesterolemic responsiveness that occurs in this species. The linkage map, comprised of polymorphic genetic marker loci including anonymous micosatellite loci and functional genes, will be developed by analysis of intergenic recombination rates determined from genotype analyses of offspring from two large backcross family panels. Fluorescence in situ hybridization (FISH) will be used to locate the physical positions of the known linkage groups on individual chromosomes. Parametric LOD-score linkage analyses and pedigree based variance components methods will be used to seek linkage between marker genes on the linkage map and genes that influence plasma lipoprotein phenotypes in a family panel that has been subjected to a dietary challenge regimen.

Summary: The overall objective of this project is to develop gutless adenovirus vectors for use in experimental animals, to determine the best protocol for prolonged expression following delivery in vivo, and to use these vectors to express low density lipoprotein receptor (LDLR) and very low density lipoprotein receptor (VLDLR) in animal models of familial hypercholesterolemia (FH). The specific aims are (i) We will examine the effect of long-term expression of VLDLR and LDLR in transgenic mice with an LDLR -/background using an inducible binary transactivation system. This system was developed by investigators in Project 3. Different levels of expression of the transgene can be accomplished by graded subphysiological doses of an exogenous compound RU486. (ii) We will develop gutless adenovirus vectors expressing reporter genes (e.g. alpha1- antitrypsin), VLDLR and LDLR which will be tested in mice and rhesus monkeys. (iii) We will develop a protocol for the repeated administration of gutless vectors to mice and rhesus monkeys. Transient immunosuppression protocols and vectors of different serotypes will be tested. (iv) We will test and compare the gutless vectors expressing mouse LDLR and VLDLR in LDLR -/- mice for their efficacy in reversing the hypercholesterolemia and their general health effects, and the extent of aortic atherosclerosis. (v) We will examine the effect of hepatic transfer of the rhesus LDLR and VLDLR genes in heterozygous and possibly homozygous LDLR-deficient rhesus monkeys. This project interacts closely with Project 2 for the gutless vector development, and Project 3 for the regulated expression system. It will be supported by the scientific Cores A (Primate Core), B (Vector Production Core) and C (Pathology Core). Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: IMMUNOBIOLOGY OF APOLIPOPROTEIN E Principal Investigator & Institution: Curtiss, Linda K.; Professor; Scripps Research Institute Tpc7 La Jolla, Ca 92037 Timing: Fiscal Year 2002; Project Start 01-DEC-1988; Project End 31-MAR-2003 Summary: Coronary artery disease, the major manifestation of atherosclerosis, is the leading cause of death in the Western world. In spite of this striking impact, the pathogenesis of atherosclerosis is till poorly understood. Controversy exists regarding the participation of innate immunity involving macrophages. (Mphi) and natural killer (NK) cells versus antigen-specific acquired immunity involving lymphocytes. Mphi predominate in atherosclerotic lesions. NK cells, although smaller in number a present as well. Furthermore the T lymphocytes that participate in acquired immunity are frequently observed in lesions and have been demonstrated to modulate lesion progression. This proposal will address directly the participation of the innate inflammatory and acquired immune responses in vivo. To demonstrate the participation of NK cells in atherosclerosis resulting from moderate as well as profound hypercholesterolemia, we will combine the use of well characterized mouse models of atherosclerosis with inbred strains of mice that are deficient in T and B cell and / or NK cell function. Our first aim is to detail the frequency and the kinetics of NK cell and T cell localization within lesions of apolipoprotein E-deficient (apo E -/-) and low density lipoprotein receptor-deficient (LDL-R-/-) mice with both moderate and severe hypercholesterolemia. This aim will determine the degree to which NK cells and T lymphocytes influence the progression of ahteroma and reveal whether T and NK cell cytokine expression are responsible for the characteristic pathology of the disease. Because the participation of NK cells will be examined in both immune-competent as well as severely immune-deficient animals, these studies will provide valuable information on the participation of NK cells will be examined in both immune-

competent as well as severely immune-deficient animals, these studies will provide valuable information on the participation of both innate and acquired immune responses in atherosclerosis. Our second aim will identify if NK cell and T lymphocyte function within atherosclerotic lesions are influenced by locally produced Mphi apo E. WE have determined that macrophage-derived apo E plays a protective role within the lesions o LDL-r-/- mice and this aim will reveal if regulation of NK cell and/or T cell function is a mechanism by which apo E bestows this protection. The successful completion of these studies will provide critical data about the role of T cells and/or NK cells in arherosclerosis that will aid in the development of new treatment strategies to alter the course of atherosclerosis in humans.

Project Title: INFLAMMATION IN VEIN GRAFT DISEASE: A GENETIC APPROACH Principal Investigator & Institution: Peppel, Karsten C.; Medicine; Duke University Durham, Nc 27710 Timing: Fiscal Year 2004; Project Start 01-JUL-2004; Project End 31-MAY-2008 Summary: (provided by applicant): Aortocoronary vein graft atherosclerosis afflicts over two million Americans. While it shares many features with atherosclerosis of native arteries, vein graft atherosclerosis progresses considerably more rapidly. Inasmuch as atherosclerosis is a chronic inflammatory disorder, inflammatory cytokines such as Tumor Necrosis Factor alpha (TNFalpha) might contribute to vascular lesion development. Preliminary studies demonstrate a strong proatherogenic activity of TNF on vascular smooth muscle cells (SMCs) in vitro. Our Central Hypothesis is that TNF contributes substantially to vein graft failure in vivo. While both activated macrophages and SMCs can produce TNF, the contribution of this cytokine to vein graft disease, and the cellular and molecular mechanisms by which TNF may accentuate vein graft atherosclerosis, are incompletely understood. To study these issues, we recently developed a new murine vein graft model that uses congenic inferior vena cavae to carotid artery interposition grafts. As a result, we can manipulate the genetic background of the vein graft wall independently from that of the recipient's circulating cells. Our preliminary studies show a significant reduction (40%) of vein graft neointima formation in grafts that are deficient in TNF receptor 1 signaling (TNFR1-/-), when placed into normolipidemic TNFR1-/- recipients. Our first aim is to determine the role of TNFalpha in vein graft atherosclerosis under normal and hyperlipidemic conditions in vivo. To achieve this aim, we will use wild type (C57Bl/6) or congenic apolipoprotein E deficient (ApoE-/-) mice as pro-atherogenic recipients of congenic vein grafts. The vein grafts will be derived from either wild type or TNF receptor-1-deficient (TNFR1-/-) mice. All of the recipient mice will also express the beta-galactosidase marker gene (from the Rosa 26 mouse strain) to allow for evaluation of vein graft infiltration by recipient-derived cells. Our second aim is to assess the potential for a recombinant TNF Inhibitor to attenuate vein graft neointima formation in mice with normal or elevated lipid levels. This will be achieved by examining vein graft remodeling in wild-type or ApoE-/- mice, that have been infected with a recombinant adenovirus expressing a p55TNFR1-IgG fusion protein that we have created. Defining cellular mechanisms by which TNF promotes vein graft atherosclerosis may have therapeutic implications for the many patients with vein graft disease.

Project Title: INFLUENCE OF DIETARY FLAVONOIDS ON THE EXPRESSION OF AT* Principal Investigator & Institution: Keen, Carl L.; Professor and Chairman; Nutrition; University of California Davis Sponsored Programs, 118 Everson Hall Davis, Ca 956165200 Timing: Fiscal Year 2002; Project Start 15-SEP-2001; Project End 31-AUG-2004 Summary: (provided by applicant) Oxidative stress is characterized by excessive concentrations of reactive oxygen and reactive nitrogen species (ROS and RNS). Excessive oxidative damage has been implicated in the pathogenesis of numerous degenerative diseases including coronary vascular diseases (CVD). A current hypothesis suggests that ROS, RNS and oxidized LDL (ox-LDL) induce the expression of atherogenic genes via redox-sensitive signaling pathways. The oxidative stress-induced gene expression has been shown to be mediated via the activation of redox sensitive transcription factors such as nuclear factor- kappaBeta (NFkB), and redox-sensitive transduction pathways such as those involving members of the mitogen activated protein kinase (MAPK) family as well as members of the Src family. Genes regulated by NFkB activation encode for proteins implicated in acute phase and inflammatory responses including certain cytokines and chemokines, cell adhesion molecules and inflammatory enzymes; several of these molecules are involved in the pathogenesis of atherosclerosis. Similarly, studies have shown that JNK, BMK-1 and cSrc are involved in signaling events stimulated by ROS that contribute to atherosclerosis such as smooth muscle cell proliferation. It is well known that diet plays a important role in a large number of chronic diseases. The investigators suggest that this is due in part to an effect of diet on a individual's antioxidant status. Vitamins and minerals contribute to the oxidative defense system because: (1) they are antioxidants (vitamins E, C and Bcarotene); (2) they are essential for the function of enzyme antioxidants (Zn, Cu, Fe, Mn, Se and riboflavin); or (3) they act to maintain low levels of potentially pro-oxidant molecules (vitamins B12, B6 and folate). On the other hand, the cardio-protective effects of flavonoids result in part from their antioxidant properties, and their ability to modulate the activity of a wide spectrum of enzymes. The researchers propose to investigate the hypothesis that diet may influence vascular redox-mediated signaling and transcriptional activities. Using the mouse model, they will test the hypothesis that a diet marginal in select micronutrients will induce a pro-oxidative state that will worsen the pathophysiological state of atherosclerosis. Finally, they will test the hypothesis that addition of flavonoids to diets marginal in antioxidants will attenuate the atherogenic effect of the pro-oxidative effect of micronutrient deficiency and hypercholesterolemia. These issues will be addressed using mutant mice in which the LDL receptor (LDLr) has been inactivated. The researchers will measure the progression of atherosclerosis in LDLr +/+ and -/- mice fed a high fat-micronutrient adequate diet, or a high fat-micronutrient marginal diet, supplemented or not with the flavonoids, quercetin and catechin. They will use biochemical markers and immunohistochemistry to evaluate antioxidant capacity and redox status in the LDLr mice, and correlate these with the severity of atherosclerosis determined by lesion progression and atherogenic gene expression. Finally, they will examine the effects of the diets on the activation of NFkB and cell signaling pathways. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Principal Investigator & Institution: Grammas, Paula; Shideler Professor; Pathology; University of Oklahoma Hlth Sciences Ctr Health Sciences Center Oklahoma City, Ok 73126 Timing: Fiscal Year 2004; Project Start 15-JAN-2004; Project End 31-DEC-2007 Summary: (provided by applicant): Alzheimer's disease (AD) is a neurodegenerative disease that affects over 4 million Americans. We are the first to demonstrate that brain blood vessels release neurotoxic proteins in Alzheimer's disease. However, the factors that cause this vessel dysfunction are not known. It is our hypothesis that risk factors involved in the pathogenesis of atherosclerosis are also causally linked to the development of vascular-mediated neuronal cell death in Alzheimer's disease. Our studies are timely and important as increasing evidence points to a link between atherosclerosis and Alzheimer's disease. Aim 1: To determine the effects of systemic oxidant stress or hyperlipidemia on vascular thrombin release, vascular-mediated neurotoxicity and on the cognitive performance of apoE transgenic mice. Brain blood vessels isolated from apoE knockout or transgenic mice expressing human E3 or E4 are used to assess the role of apoE isoforms on vascular expression of thrombin. Dietinduced hyperhomocystinemia and hyperlipidemia, are used to assess the role of oxidant stress and lipids, respectively, on vascular thrombin release and vascularmediated neurotoxicity. Also, these transgenic mice are utilized to evaluate possible apoE isoform-specific effects of oxidant and lipid stress on impairments in learning and memory. Aim 2: To determine if risk factors involved in the pathogenesis of atherosclerosis are also causally linked to the development of vascular-mediated neuronal cell death in Alzheimer's disease. Brain microvessels are isolated from AD patients and non-demented patients and analyzed for levels and/or activity of thrombin and other possible neurotoxic proteins, including, matrix metalloproteinases (MMPs), inflammatory cytokines and chemokines, and endothelin-l. Protein levels are determined by ELISA and Western blots and Mrna levels assessed by Northern blots and RT-PCR. The role that apoE isoforms play in regulating these proteins is determined by comparing microvessels isolated from patients with different APOE genotypes. In vitro addition of oxygen species or lipid molecules to isolated brain microvessels is used to assess the effects of oxidative stress and lipids, respectively, on release of thrombin, MMPs, inflammatory proteins, and endothelin-l. Apoptosis and necrosis are measured in cultured neuronal cells exposed to these proteins. These results would, for the first time, identify a mechanistic cascade linking cardiovascular risk factors to vascularmediated neuronal cell death in Alzheimer's disease and identify novel targets for therapeutic intervention.

Project Title: ISOPRENOID METABOLISM IN THE RETINA Principal Investigator & Institution: Fliesler, Steven J.; Professor; Ophthalmology; St. Louis University St. Louis, Mo 63103 Timing: Fiscal Year 2002; Project Start 01-MAR-1988; Project End 31-MAR-2005 Summary: (provided by applicant): The long-range goal of this project is to determine the biological roles of cholesterol (CHOL) and related molecules in the retina in both normal and pathological states. Oxygenated derivatives of CHOL and other sterols occur naturally in cells and tissues, being formed both by autoxidation as well as enzymatically. Such "oxysterols" regulate normal cellular physiology, but also are potent

cytotoxins that have been implicated in diseases such as atherosclerosis, diabetes, and cancer. The involvement of oxysterols in retinal diseases is unknown and has yet to be investigated. However, given the association between hypercholesterolemia and atherosclerosis as risk factors in prevalent retinal diseases such as age-related macular degeneration (AMD), research in this area seems warranted. Herein, we evaluate the formation and biological activity of oxysterols in the retina of normal rats in comparison with those that have been treated with a drug (AY9944) that causes accumulation of 7dehydrocholesterol (7DHC) in the retina and other tissues. AY9944-treated rats are an animal model for the Smith-Lemli-Opitz syndrome (SLOS), a common, autosomal recessive disease with associated ophthalmic defects, including retinal dysfunction. New results presented herein show that AY9944-treated rats develop retinal dysfunction prior to obvious histological damage, yet when exposed to intense green light for only 24 h, a massive, rapid retinal degeneration ensues that is much more severe and extensive than occurs in normal rats under the same conditions. We will examine the time course of retinal degeneration in AY9944-treated rats relative to controls, in both normal, dim cyclic lighting and with the "light damage" paradigm, correlating retinal structure and function with the formation, amounts, and types of oxysterols in the retina. We will compare the effects of intravitreally-injected oxysterols on the structure and function of the retina in normal rats, with and without pretreatment with dimethylthiourea (DMTU), a potent antioxidant. We also will evaluate the ability of DMTU pretreatment to reduce or prevent both oxysterol formation and the retinal damage observed in AY9944-treated and normal rats following exposure to intense green light.

Project Title: LIPID TESTING /TREATMENT IN OLDER MI PATIENTS Principal Investigator & Institution: Foody, Joanne M.; Internal Medicine; Yale University 47 College Street, Suite 203 New Haven, Ct 065208047 Timing: Fiscal Year 2002; Project Start 15-SEP-2002; Project End 31-AUG-2006 Summary: (provided by applicant): While it is clearly established that elevated total and low density lipoprotein cholesterol predict future cardiac events in younger patients, there is lack of consistent data regarding the prognostic value of these lipoproteins in elderly (age >75) patients with CAD. Further, while lipid lowering therapy is associated with significant clinical benefits in patients less than 75 years with MI, no randomized clinical trial has assessed their efficacy in the older (>75) patient with MI. Finally, older patients? knowledge, beliefs and preferences regarding prevention have not been elucidated. The proposed project seeks specifically to broaden our understanding of the prognostic role of cholesterol n the elderly, provide insight into the effectiveness of lipid lowering, and determine domains of 0 der patients? preferences regarding lipid lowering and preventive care. This is a research plan with four specific aims. Aims 1,2, and 3 address critical gaps in knowledge surrounding lipids n the elderly utilizing an innovative collaboration between academia and the National AMI project, a quality improvement initiative sponsored by HCFA. This project, organized and implemented by the current investigators, contains medical record abstraction for over 250,000 Medicare beneficiaries hospitalized with MI in the U.S. in 1994-1995 and 1998-1999. The investigators seek to use data and enrich them to create research database capable of producing knowledge about lipid lowering therapy and future efforts to improve I the care and outcomes of older persons with MI. Aim 4 extends research into patient preferences in the elderly, l a generally unexamined area. This phase will use qualitative methodology to ascertain older patients? preferences regarding preventive treatment,

treatment goals and quality of life, and to develop a taxonomy for elderly patients? primary prevention treatment preferences. Capitalizing on institutional strengths in outcomes research, geriatrics, and cardiology, the proposed research builds on prior work to form the basis for a sustained career in prevention in the elderly. The applicant will gain experience and insight to conduct independent health services research aimed at improving quality of care and clinical outcomes for older people with cardiovascular disease. This work will ultimately improve care for the elderly patient with cardiovascular disease. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: LIPOPROTEIN PATHOPHYSIOLOGY Principal Investigator & Institution: Albers, John J.; Research Professor of Medicine; Medicine; University of Washington Grant & Contract Services Seattle, Wa 98105 Timing: Fiscal Year 2002; Project Start 01-MAY-1983; Project End 31-MAR-2004 Summary: Premature vascular disease in young hyperlipidemic subjects remains a major unsolved health problem in terms of pathogenesis and treatment. Recent research advances have led to new markers for genetic analysis, new methods for studying lipoprotein metabolism and atherosclerotic disease progression and regression, and reference values for diagnosing hyperlipidemia. With these advances, the opportunity now exists for further in-depth focused studies of lipoprotein physiology and pathophysiology in genetically characterized patients with the objectives of understanding disease mechanisms, developing better treatments, and identifying and preventing early vascular disease. This will be accomplished by focusing our attention on the molecular, genetic and pathophysiological basis of the inherited dyslipoproteinemias associated with premature coronary artery disease with particular reference to familial combined hyperlipidemia, familial moderate hypercholesterolemia, familial elevation of Lp(a) and the carrier state for homocysteinemia. Coordinated studies of characterization of the pathophysiological state, the identification of possible molecular biological defects and the evaluation of these results in families by statistical genetic techniques will be performed in each disorder. The role of protein mediated intravascular modification of lipoproteins and the role of oxidation of lipoproteins in each disorder will lead to characterization of these genetic lipoprotein abnormalities. The Program Project, comprised of four coordinated projects, four supporting core facilities and a multidisciplinary team of investigators will combine the expertise in physiology, molecular biology, biochemistry, genetics, immunochemistry, nutrition, endocrinology, metabolism, epidemiology, and statistical genetics, to study lipoprotein physiology and pathophysiology at several levels of biological organization from basic molecular and cell biology through in vivo studies in humans to studies in populations.

Project Title: MECHANISM OF ACTIVATION OF THE JNK PATHWAY BY BILE ACIDS Principal Investigator & Institution: Gupta, Seema; Microbiology and Immunology; Virginia Commonwealth University Richmond, Va 232980568 Timing: Fiscal Year 2004; Project Start 01-APR-2004; Project End 31-MAR-2007 Summary: (provided by applicant): The studies in this proposal address the specific role that signaling pathways play in regulation of bile acid biosynthetic enzymes, specifically the enzyme cholesterol 7 alpha-hydroxylase (CYP7A1), the rate-limiting enzyme in the
32
Hypercholesterolemia
neutral pathway of bile acid biosynthesis. Recent findings from our laboratory provide strong evidence that activation of the c-Jun N-terminal Kinase (JNK) pathway by bile acids plays a pivotal role in regulation of CYP7A1 in primary rat hepatocytes. However, the molecular events by which bile acids activate this pathway have not yet been fully elucidated, but may have important implications in the pathogenesis of hypercholesterolemia and cholestatic liver diseases. It is proposed that interplay of ceramide and FAS within outer membrane lipid rafts is capable of regulating CYP7A1 through JNK activation. The objectives of this application are to (1) determine the mechanism(s) of activation of the JNK pathway by bile acids by defining the role of the FAS receptor in the activation of JNK in primary hepatocytes, (2) investigate the involvement of sphingomyelinases and ceramide in activation of the FAS receptor by bile acids, (3) determine whether the mechanism(s) of in vitro regulation of CYP7A1 by bile acids also apply in vivo, using FAS and acidic sphingomyelinase knock-out mice. An integrative approach combining kinase assays, ceramide measurements, fluorescence imaging, serum lipid analysis, and other molecular biology techniques will be applied to the proposed studies. Studies will be performed at Virginia Commonwealth University's-Medical College of Virginia Campus. The Department of Microbiology and Immunology and the Liver Centre at VCU are fully committed to support this research endeavor and to further develop the candidate's research career by providing the protected time, resources, and continuing research educational opportunities. This will enable the candidate to achieve her long term career goals of forming a fundamental understanding of bile acid-mediated signaling to serve as a basis for the development of effective therapies to reduce serum cholesterol levels and limit cholestasis-associated liver damage, and to develop an independent and successful research career.

Project Title: MECHANISM OF ENDOCYTIC TRAFFICKING OF CHOLESTEROL Principal Investigator & Institution: Ory, Daniel S.; Assistant Professor; Medicine; Washington University Lindell and Skinker Blvd St. Louis, Mo 63130 Timing: Fiscal Year 2002; Project Start 01-APR-2002; Project End 31-MAR-2006 Summary: (Provided by applicant): Hypercholesterolemia is a major risk factor for the development of coronary artery disease (CAD) and cerebral vascular disease (CVD). Increased plasma levels of low-density lipoprotein (LDL) leads to deposition of excess cholesterol in arteries, initiating atherosclerosis. While homeostatic mechanisms that regulate LDL uptake and de novo synthesis of cholesterol are well characterized, the cellular mechanisms that regulate trafficking of LDL cholesterol after internalization are not well understood. Evidence is emerging that the NPC1 and HE1 proteins participate in a common pathway for the efficient trafficking of internalized membrane cholesterol to the plasma membrane (PM) and to the ER. We hypothesize that NPC1 promotes formation of vesicles and/or tubules through the budding of the limiting endosomal membrane. NPC1-containing vesicles then traffic to the PM or ER to deliver their sterol cargo. The purpose of this project is to identify the molecular machinery in the sterol trafficking pathway and to test our hypothesis regarding this role of NPC1 in the sorting and distribution of internalized membrane cholesterol. This will be achieved by the following specific aims: (1) Use of a functional mammalian genetic screen to isolate Chinese hamster ovary (CHO) mutants with impaired intracellular trafficking of cholesterol, (2) Characterization and identification of the cholesterol trafficking defects in the mutant CHO cell lines, and (3) Compositional and functional analysis of proteins in the NPC1-containing late endosomal compartment, and examination of whether

NPC1 membrane vesciulation is dependent on sterol concentrations and/or an intact sterol-sensing domain in NPC1. The studies outlined in this proposal will further our understanding of the critical role of NPC1 in cholesterol homeostasis. Furthermore, study of the function of gene products identified by our genetic screens and by compositional analysis of the NPC1-containing endosomal compartment may identify novel targets within the sterol transport pathway for pharmacologic therapy of CAD and CVD.

Project Title: MECHANISMS OF P42/44MAPK-INDUCED LDL RECEPTOR EXPRESSION Principal Investigator & Institution: Mehta, Kamal D.; Molecular/Cellula/Biochemistry; Ohio State University 1960 Kenny Road Columbus, Oh 43210 Timing: Fiscal Year 2002; Project Start 01-AUG-2001; Project End 31-AUG-2005 Summary: Of all known risk factors promoting coronary artery disease, a high serum low density lipoprotein (LDL) level is the most important. The regulation of hepatic LDL receptor expression is a potential mechanism by which dietary and humoral factors alter plasma LDL levels, and upregulation of LDL receptor expression is the basis for current treatment of hypercholesterolemia. The negative regulation of LDL receptor transcription by sterols has been extensively delineated; however, the molecular mechanisms of induction and the signaling cascades controlling activity of critical nuclear factor(s) are not known. Recently, we provided the first evidence that specific activation of the p42/44mitogen-activated protein kinase (MAPK) is not only required but is sufficient to fully induce LDL receptor expression. Our recent observations supporting the requirement of CREB-binding protein (CBP) in p42/44MAPK-induced LDL receptor transcription are the basis of Specific Aim 1, and the studies proposed will link CBP acetyltransferase activity with modification of sterol responsive element binding proteins (SREBPs) and/or chromatin remodeling in the promoter region. Effects of CBP-SREBP protein-protein interactions on transactivation and on chromatin structures during the induction process will be examined by using a p42/44MAPKresponsive mammalian two-hybrid system and in vivo footprinting techniques. The Specific Aim 2 will study interleukin-1beta- and hepatocyte growth factor-induced LDL receptor expression to examine how p42/44MAPK participates during induction by sterol-sensitive and sterol-independent mechanisms. The Specific Aim 3 will establish a negative relationship between stress-activated p38MAPK alpha- isoform and LDL receptor expression and then examine the role of p38MAPK activation in stress-induced hypercholesterolemia through suppression of LDL receptor expression. This aim is based on our observation that specific inhibition of p38MAPK alpha-isoform induces LDL receptor expression via suppression of p42/44MAPK. Finally, in light of the crucial roles of MAPKs in hepatic cells, the Specific Aim 4 will examine the roles of p42/44MAPK and p38MAPK cascades in regulating expression of LDL and scavenger receptors that are a critical determinant of lipid accumulation in the macrophages and their conversion to foam cells. Defining the molecular mechanisms and the signaling pathways regulating the induction process will help in understanding the pathologic states under which the receptor pathways are perturbed, resulting in hypercholesterolemia. This knowledge could be exploited to develop improved hypercholesterolemia therapies and to reduce foam cell formation. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: MECHANISMS HOMOCYSTEINEMIA

DYSFUNCTION
IN
Principal Investigator & Institution: Lentz, Steven R.; Associate Professor; Internal Medicine; University of Iowa Iowa City, Ia 52242 Timing: Fiscal Year 2004; Project Start 01-AUG-2000; Project End 31-JUL-2008 Summary: (provided by applicant): Hyperhomocysteinemia, or elevation of plasma total homocysteine, is an emerging risk factor for cardiovascular disease and stroke. Numerous retrospective and prospective studies have suggested that hyperhomocysteinemia is an independent risk factor, and that the magnitude of risk is similar to that for conventional risk factors such as hypercholesterolemia or hypertension. The potential cardiovascular benefits of homocysteine-lowering therapy are currently being evaluated in several prospective clinical trials. Despite its clear association with clinical cardiovascular disease, however, the mechanisms responsible for the vascular pathology of hyperhomocysteinemia are still incompletely understood. Our group was among the first to demonstrate that moderate hyperhomocysteinemia produces impaired vascular function in vivo. To better examine the mechanisms of vascular dysfunction in hyperhomocysteinemia, we have developed genetic and dietary approaches to produce hyperhomocysteinemia in mice. Our data, and data from others, have provided strong evidence that endothelial dysfunction during hyperhomocysteinemia is related to impaired bioavailability of endothelium-derived nitric oxide (NO). Proposed mechanisms include oxidative inactivation of NO and decreased production of NO due to inhibition of endothelial nitric oxide synthase by asymmetric dimethylarginine (ADMA). The goals of this project are to define the role of ADMA in decreasing NO bioavailability and to determine the sources of reactive oxygen species (ROS) that mediate vascular dysfunction in hyperhomocysteinemia. A key feature of our experimental design is the use of genetically-altered mice to examine the contributions of ADMA, the inducible isoform of nitric oxide synthase, and vascular NAD(P)H oxidases in impairing endothelial function during hyperhomocysteinemia. This project has the potential to suggest novel therapeutic approaches to the prevention and treatment of vascular disease associated with hyperhomocysteinemia.

Principal Investigator & Institution: Reilly, Muredach P.; Assistant Professor of Medicine and Phar; Medicine; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2002; Project Start 01-AUG-2000; Project End 31-JUL-2005 Summary: PROPOSAL (Adapted from the applicant's abstract): Atherosclerosis remains the leading cause of death in the developed world. The signaling pathways involved in this chronic inflammatory disorder of the vasculature are poorly understood. PKC isozymes are potentially critical intracellular mediators of atherosclerotic regulatory signals in vivo. Recent data are consistent with a specific role for PKC in angiogenic signaling in vitro and in the development of vascular complications of diabetes in vivo. One of the challenges in the PKC field is to dissect the distinct roles of individual isozymes of PKC in atherosclerosis. It is the long-term goal of the applicant to determine the isozyme specific functions of PKC in atherosclerosis in vivo with a view to developing novel pharmacological therapies aimed at retarding this process in humans. Presently, it is unknown which PKC isozymes are activated in atherosclerotic tissue in

vivo. Thus, despite the recent development of specific PKC inhibitors for use in humans, the isozymes that represent the best potential targets in atherosclerosis have not been identified. The investigator's specific aims, therefore, are: 1) to identify isozyme specific PKC activation in atherosclerotic mouse models and to modulate their activity in these models; 2) to confirm isozyme specific activation in human atherosclerosis and to investigate the effects on endothelial function of inhibition of specific isozymes inpatients with hypercholesterolemia; and 3) to examine the relevance of specific isozymes to angiogenesis in vitro and in vivo. By working closely with a multidisciplinary group with a strong background in both basic and translational research the applicant strives to obtain the practical experience necessary to develop an independent career in clinical investigation. Focussed coursework in patient-oriented research will compliment practical experience obtained during the development of this application.

Project Title: METABOLIC EFFECTS OF PROTEASE INHIBITORS IN HIV DISEASE Principal Investigator & Institution: Mulligan, Kathleen; Associate Professor; Medicine; University of California San Francisco 500 Parnassus Ave San Francisco, Ca 941222747 Timing: Fiscal Year 2002; Project Start 30-SEP-1998; Project End 31-AUG-2004 Summary: (Adapted from applicant's abstract). Reports of increased glucose triglyceride, and cholesterol levels in HIV-infected patients on protease inhibitors (PI) have prompter speculation that these agents have unique metabolic effects. Additionally, some HIV-infected patients have noted increased abdominal girth and buffalo humps that clinicians and patients attribute to the use of Pi's. In preliminary studies, we have observed significant increases in glucose, insulin, TG and total LDL cholesterol in a group of patients following initiation of therapy with a PI, whereas no such changes occurred in patients beginning therapy with lamivudine or maintaining constant regimen that did not include lamivudine or a PI. Because hyperglycemia, hypertriglyceridemia, hypercholesterolemia, and central obesity are associated with increased risk of cardiovascular disease, these effects may impact on the long-term prognosis in patients whose life expectancies are extended due to effective viral suppression. As yet, these metabolic and body composition changes have not been systematically characterized, nor is it known if these changes represent one year syndrome or are unrelated findings. Therefore, to evaluate the scope of and mechanisms underling these changes in carbohydrate and lipid metabolism and their relationship, if any, to changes in body composition, e propose to perform intensive metabolic ward studies in which we prospectively evaluate changes in glucose and lipid metabolism and body composition in separate cohorts of HIV-infected men and women before and after beginning Pi therapy. These studies are designed to: (1) test the hypothesis that PI's induce insulin resistance (as assessed by oral glucose tolerance test, hyperinsulinemic, euglycemic clamp, stable isotope studies of hepatic glucose production, gluconeogenesis and glycogenesis); 2) test the hypothesis that PI's produce an atherogenic lipid profile (plasma lipids and lipoprotein composition, intravenous fat tolerance test, stable isotope studies of whole body lipolysis, de novo hepatic lipogenesis, and cholesterolgenesis); and (3) to determine whether patients uniformly develop changes in regional fat distribution while on PI therapy and the relationship, if any, or changes in glucose and lipid metabolism to changes in body composition (dual-energy X-ray absorptiometry, computed tomography)> The role of glucoregulatory, adrenal, and gonadal hormones in mediating these effects will also be evaluated.

Project Title: MOLECULAR PHYSIOLOGY OF BILIARY LIPID SECRETION Principal Investigator & Institution: Cohen, David E.; Associate Professor; Medicine; Yeshiva University 500 W 185Th St New York, Ny 10033 Timing: Fiscal Year 2003; Project Start 01-FEB-1996; Project End 31-JUL-2008 Summary: (provided by applicant): Bile is the principal pathway for cholesterol elimination from the body, and high density lipoproteins (HDL) in plasma are the principal source of biliary cholesterol. However, hepatocellular mechanisms for uptake, transport and biliary secretion of HDL-derived cholesterol remain poorly understood. Scavenger receptor class B type I (SR-BI) is highly expressed in liver and promotes uptake of HDL lipids. Caveolae are cholesterol- and sphingolipid-rich membrane microdomains, which participate in cellular cholesterol transport. Both caveolin-1, the structural protein of caveolae, and SR-BI are expressed on the sinusoidal and canalicular domains of hepatocyte plasma membranes. Specific Aims 1 and 2 of this proposal will test the hypothesis that caveolae constitute a vesicular pathway that is responsible for sinusoidal HDL uptake and delivery to the canalicular membrane. Using mice with targeted disruption of genes encoding caveolin-1 and SR-BI, Specific Aim 1 will explore contributions of caveolin-1 and SR-BI to hepatic lipoprotein clearance and biliary lipid secretion. Primary cultures of hepatocytes from genetically engineered mice will be used to dissect contributions of caveolin-1 and SR-BI to binding and uptake of HDL. Specific Aim 2 will examine a role for caveolae in trafficking of HDL through the hepatocyte. Real time confocal fluorescence microscopy of HUH-7 hepatoma cells, which have been transfected with a green fluorescent protein-caveolin-1 fusion protein, will be employed to characterize uptake of luorescence-labeled HDL, processing within the endosomal compartment and trafficking to the canalicular membrane. An in vitro vesicle motility assay will be used to explore a role for microtubules in transport and sorting of vesicles containing HDL, SR-BI and caveolin-1. Hepatocellular secretion of phosphatidylcholines into blood and bile is critical for HDL metabolism and bile formation, respectively. Phosphatidylcholine transfer protein (PC-TP) is a cytosolic lipid transfer protein of unknown function that is highly expressed in liver. Specific Aim 3 will utilize PC-TP knockout mice to test the hypothesis that PCTP provides a nonvesicular pathway for phosphatidylcholine transport to the plasma membrane for incorporation into biliary vesicles and HDL particles. PC-TP knockout mice will be used to explore a role for this protein in biliary elimination of plasma cholesterol. These studies should elucidate the mechanisms of biliary lipid secretion at a fundamental cellular level and potentially lead to early interventions in cholestasis and cholelithiasis, as well as new strategies for management of hypercholesterolemia.

in humans, while partial inhibition can be used to treat hypercholesterolemia and cholestasis. ASBT is expressed on the apical surface of ileal enterocytes, renal tubules, and cholangiocytes. In the rat ileum, ASBT undergoes a biphasic pattern of developmental expression. Bile acid responsiveness of ASBT is species specific. ASBT is down regulated in the ileitis and up regulated by corticosteroids. Adaptation by ASBT after intestinal resection is dependent upon the length of residual ileum. These changes in ASBT expression are controlled at the level of transcription and mRNA stability. The rat, mouse, and human ASBT promoters have been cloned in my laboratory. HNF1alpha, AP-1 and LRH-1 are critical elements in the transcriptional regulation of ASBT. This proposal will define the molecular mechanisms involved in the regulation of the ASBT gene. Transcriptional regulation will be studied with chimeric luciferase promoter reporter constructs, DNA:protein gel shift analysis, and transgenic mice. Molecular mechanisms of transcriptional modulation of ASBT gene expression will be analyzed in normal physiology and pathologic states (altered bile acid homeostasis, ileal inflammation and intestinal resection). The role of mRNA stability will be assessed by identification of mRNA destabilizing elements in the ASBT transcript and by characterization of RNA:protein interactions. Cell-free systems and/or transgenic animals will be utilized to assess the role of these elements in developmental-stage and organ specific expression. The results of these studies will be highly significant in light of the crucial role that ASBT plays in human health and disease. The ASBT gene also represents a valuable model of important and poorly defined biological processes in the intestine, such as transcriptional regulation of ontogeny and tissue specificity and the role of mRNA stability in intestinal gene regulation.

Project Title: NONALCOHOLIC FATTY LIVER DISEASE IN HISPANIC OBESE YOUTH Principal Investigator & Institution: Butte, Nancy F.; Associate Professor of Pediatrics; Pediatrics; Baylor College of Medicine 1 Baylor Plaza Houston, Tx 77030 Timing: Fiscal Year 2004; Project Start 15-JAN-2004; Project End 31-DEC-2005 Summary: (provided by applicant): Childhood obesity and type II diabetes are reaching epidemic proportions in the U.S. particularly among Hispanic and African-American children, and the consequences of this epidemic in terms of nonalcoholic fatty liver disease (NAFLD) are understudied and under appreciated. Hispanic and AfricanAmerican children are at greater risk for the development of obesity and type II diabetes which are major risk factors for NAFLD. The full impact of this metabolic syndrome will not be realized until these children become adults and develop the long-term consequences of obesity, diabetes and liver disease. The primary objective of this grant is to characterize children at risk for NAFLD and explore possible mechanisms underlying the development of NAFLD in 1000 Hispanic children enrolled in an ongoing NIH genome-wide linkage study designed to identify genes that influence the expression of childhood obesity. The long-term objective is to develop an clinical intervention trial to treat the adverse effects of NAFLD in obese children. Hypothesis: Oxidative stress, endotoxemia and systemic inflammation superimposed on hepatic fat accumulation may lead to liver damage in obese children. Specific Aims: 1. To characterize Hispanic children at high risk of developing NAFLD in terms of age, gender, body composition, diet, physical activity, and severity and duration of obesity. 2. To determine the relationships between fasting hypertriglyceridemia, hypercholesterolemia, hyperinsulinemia and hyperleptinemia, and elevations in serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST). 3. To obtain

We will characterize children at risk for NAFLD and explore possible mechanisms of oxidative stress, endotoxemia and systemic inflammation underlying NAFLD. Methods: Liver function tests, ALT and AST will be analyzed in relation to in-depth phenotyping and genetic linkage analysis performed under the on-going NIH study. Newly proposed tests include chromogenic assays to measure lipid peroxidation end products and endotoxins, and ELISA and RIA to measure cytokine and markers of systemic inflammation.

Project Title: NOVEL DRUG TARGET FOR BILE AND CHOLESTEROL METABOLISM Principal Investigator & Institution: Thacher, Scott M.; Orphagen Pharmaceuticals 5310 Eastgate Mall San Diego, Ca 921212804 Timing: Fiscal Year 2003; Project Start 15-AUG-2003; Project End 31-MAY-2004 Summary: (provided by applicant): Regulation of bile acid metabolism is a therapeutic target for treatment of hypercholesterolemia as well as for cholestasis, the pathological buildup of bile in liver. Therapeutic options for direct modulation of hepatic bile formation and transport are limited. Orphagen proposes to develop and commercialize lead molecules that regulate gene transcription by the orphan nuclear receptor LRH-1 (liver receptor homolog-1). LRH-1 appears to stimulate reverse cholesterol transport, bile formation, and bile transport. The effort to identify the first pharmacologically active compounds to LRH-1 is part of a larger program to create drugs to structurallyrelated orphan nuclear receptors that regulate mammalian steroid and cholesterol metabolism. In Phase I, an indirect binding assay for compound screening at LRH-1 will be implemented based on findings from Drs. Holly Ingraham and Kip Guy at U. C. San Francisco. LRH-1 will be screened against a focused small molecule compound library developed at Orphagen. Cell-based reporter gene assays will be implemented in parallel to accelerate identification and confirmation of small molecules that regulate gene transcription by LRH-1. Drug candidates suitable for animal studies of hypercholesterolemia and cholestasis will be synthesized and tested in Phase II and a strategic partner recruited for further development.

Project Title: NUTRITION INTERVENTION: METABOLIC COMPLICATIONS OF HIV+ Principal Investigator & Institution: Woods, Margo N.; Associate Professor; Family Medicine & Cmty Health; Tufts University Boston Boston, Ma 02111 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-JUL-2007 Summary: (provided by applicant): As the HIV population survives and ages, a new syndrome is being observed that appears to be affected by PI medications but is also seen independent of PI use. This syndrome is characterized by hyperlipidemia, lipodystrophy and insulin resistance. Elevated triglycerides are a common observation with or without hypercholesterolemia. Since statin do not reduce serum triglycerides and may be counter-indicated to lower serum cholesterol because of potential liver damage in the HIV+ population that are on PI, dietary interventions have been getting more attention. Literature suggests that a diet lower in fat with reduced levels of

saturated fat relative to polyunsaturated fat, increased omega 3-fatty acids intake, high fiber, and use of carbohydrates lower in glycemic index may be beneficial when they were studied individually. We propose to use a nutrition intervention in a HIV+ population that has elevated triglycerides (>220 mg/dl) to test whether a diet that combines all of these factors can have a significant effect on reducing serum triglycerides. The nutrition intervention will be a low fat diet (25% of calories from fat) with a 1:1:1 ratio of Saturated:Monounsat: Polyunsaturated fat, high in fiber (40 g/day) with carbohydrates of lower glycemic index (< 70 whenever possible). This diet will contain 3 g/day of omega 3-fatty acids which will be supplemented with 3.0 g of omega 3-fatty acids from capsules to give a total of 6 g/day of omega 3-fatty acids and a ratio of n-6/n-3 of 4:1. In addition to measuring triglycerides, serum cholesterol and its subfractions will be determined as well as insulin area under the curve (AUC) and body composition using CT scan. HIV+ participants eligible for the study (N=100) would be randomized into a control or nutrition intervention group and be tested for changes after 3 weeks, 13 weeks and 6 months of intervention. During the first 3 weeks the intervention group will be given all their meals at the hospital General Clinical Research Center, followed by an additional 10 weeks in which some food products are supplied to them along with the continued use of omega 3-fatty acids supplements at 3 gms/day (in 10 capsules). After 13 weeks the participants will be asked to continue to take the omega 3-fatty acid capsules but food products high in n-3 fatty acids will not be supplied. A 6-month follow-up will then remeasure all the study parameters to determine if the nutrition intervention group had experienced an improvement of the listed risk factors compared to the control group.

Project Title: OSTEOBLASTOGENESIS IN AORTIC VALVE CALCIFICATION Principal Investigator & Institution: Rajamannan, Nalini M.; Feinberg Cardiovascular Inst; Northwestern University Office of Sponsored Research Chicago, Il 60611 Timing: Fiscal Year 2003; Project Start 01-SEP-2003; Project End 31-AUG-2007 Summary: (provided by applicant): This proposal is for a new K08 application which proposes a detailed plan for the candidate's research and a 4-year goal driven plan for further career development. The candidate's career goal is to become a successful independent scientific investigator. A career development plan is described that delineates the specific goals over the award period and the mechanisms that will be used to achieve them. Through didactic training and ongoing supervision through mentors and advisory committee, the candidate expects to 1) further develop as a basic science investigator, 2) conduct the proposed study with the highest degree of quality 3) present and publish studies in valvular heart disease at National conferences and leading journals 5) compete for advanced sources of funding and 6) develop insights in to the pathogenesis of valvular heart disease. The underlying mechanism for the pathogenesis of calcific aortic stenosis is unknown. This trend is becoming more pronounced with the aging population. Clinical studies indicate parallel risk factors for vascular atherosclerosis and aortic valve disease, the principle causative factor is elevated cholesterol levels. Due to these clinical observations, the PI has developed a translational approach to studying aortic valve disease. It is our hypothesis that calcification of the aortic valve is a direct result of valvular cellular transformation to an osteoblast phenotype that is initiated by hypercholesterolemia. The PI plans to test the hypothesis by the following specific Aims: Aim 1: Using the in vivo rabbit model, analyze the effects of hypercholesterotemia with and without statins in the atherosclerotic and proliferative aortic valve. Aim 2: Using the in vivo rabbit model,

analyze the effects of hypercholesterolemia with and without statins in the calcification and mineralization of aortic valve. Aim 3: Using the in vivo rabbit model, determine the specific signaling pathways in the aortic valve which mediate the development of aortic valve atherosclerosis and osteoblastogenesis. Aim 4: Imaging the in vivo rabbit model of aortic valve disease. These studies provide the first in vivo model of aortic valve calcification which correlate the epidemiologic studies of atherosclerotic risk factors to the development of calcific aortic valve disease. If hypercholesterolemia stimulates the development of calcification in the aortic valve then the use of medical therapy such as HMG CoA reductase medications may have a role in the medical therapy of calcific aortic stenosis.

Project Title: OSTEOGENIC CALCIFICATION
REGULATION

MACROVASCULAR
Principal Investigator & Institution: Towler, Dwight A.; Chief, Division of Bone and Mineral Dise; Barnes-Jewish Hospital Ms 90-94-212 St. Louis, Mo 63110 Timing: Fiscal Year 2002; Project Start 30-SEP-2001; Project End 31-JUL-2003 Summary: (provided by applicant): Epidemiology suggests that diabetes and hypercholesterolemia increase risks for atherosclerotic & osteoporotic diseases. The regulation of vascular calcification is poorly characterized; the LDLR -/- mouse model & human valve specimens implicate heterotopic osteogenic mechanisms. It is important to understand aortic calcification and metabolism in our aging population since pharmacotherapies implemented to promote bone formation & preserve bone mass may alter progression of calcific vasculopathy. The 3 specific aims of this proposal are: Aim 1: "To characterize the activities of prolonged dysmetabolic exposure and osteoanabolic pharmacotherapy on orthotopic (skeletal) vs. heterotopic aortic osteogenic gene expression programs, using the diabetic LDLR -/- mouse as a model." In vivo data suggest overlapping yet distinct transcription mechanisms are rate limiting in the initiation of orthotopic vs. aortic calcium deposition. We will directly assess the aortic vs. osseous responses to osteoanabolic pharmacotherapy in the presence or absence of the dysmetabolic state. PTH will be used as a relevant, prototypic osteoanabolic stimulus in the dysmetabolic LDLR -/- mouse model. Gene expression of key osteogenic transcription factors, morphogens, & matrix molecules will be quantified by fluorescence RT-PCR, & spatially resolved by in situ hybridization. Temporo-spatial deposition of aortic calcium will be quantified by image analysis of von Kossa stained sections. Aim 2: "To identify the transcriptional mechanisms that regulate aortic mesenchymal cell osteogenic gene expression, using the osteopontin (OPN) & Msx2 promoters as models for study." The goal is to identify specific DNA-protein interactions that mediate responses to dysmetabolic signals (e.g., diabetes, hyperlipidemia) that control expression of these key osteogenic genes in vascular smooth muscle cells, peri-aortic adventitial cells, and osteoblasts using (a) transfection and gel shift analyses in primary cell cultures and cell lines; and (b) cDNA cloning techniques. Aim 3: "To identify if the gene expression programs elaborated during aortic calcification in the diabetic, hyperlipidemic LDLR -/- mouse provide a molecular phenocopy of human aortic calcification via molecular analysis of calcified human valves." We will determine if human aortic valve calcification quantified by spiral CT is associated with up-regulation of specific osteoblast transcriptional regulatory programs controlled by Msx2, Dlx5, & Runx2/Cbfa1/Osf2 (osteoblast transcription factors). Gene expression will be quantified by fluorescence RT-PCR and spatially resolved by in situ

Project Title: OVEREXPRESSION OF ENOS IN CRITICAL LIMB ISCHEMIA Principal Investigator & Institution: Messina, Louis M.; Associate Professor; Surgery; University of California San Francisco 500 Parnassus Ave San Francisco, Ca 941222747 Timing: Fiscal Year 2004; Project Start 01-JAN-2004; Project End 31-DEC-2009 Summary: (provided by applicant): Despite advances in the surgical and catheter-based treatments for critical limb ischemia (CLI), 150,000 patients require lower limb amputation in the United States annually. Believing that an effective molecular therapy would have a significant clinical impact on the disability and limb loss rates in these patients, this study looks specifically at the role of endothelial nitric oxide synthase (eNOS) in collateral artery development (arteriogenesis). Because such development can reverse CLI, our central hypothesis maintains that the overexpression of eNOS will induce the ordered and sustainable development of collateral arteries in a way that will reverse CLI. Specifically, this research proposal aims 1) to identify the optimal gene transfer condition in a rat hind limb mode of ischemia; 2) to examine whether these eNOS gene transfer techniques can also reverse CLI clinically relevant animal models of diabetes, advanced age and hypercholesterolemia, and cigarette smoking; and 3) to characterize the molecular mechanisms by which eNOS overexpression increases arteriogenesis. To accomplish these aims, our research plan employs novel gene delivery techniques and sites of delivery. In particular, a unique method of intra-arterial gene transfer under vascular isolation that results in highly efficient and localized transgene expression will be used for gene transfer and laser Doppler perfusion imaging to measure dermal blood flow will facilitate the accomplishment of the above aims. Understanding the mechanisms by which eNOS exerts its powerful effects on arteriogenesis should provide additional insight into the fundamental mechanisms regulating arteriogenesis, and therefore open new therapeutic approaches for the treatment of CLI and other vascular diseases.

Project Title: OXIDATION RISK FACTORS AND IMT PROGESSION IN FH Principal Investigator & Institution: Hopkins, Paul N.; Research Associate Professor; Internal Medicine; University of Utah Salt Lake City, Ut 84102 Timing: Fiscal Year 2002; Project Start 01-SEP-2000; Project End 31-AUG-2005 Summary: (Verbatim from the application): In 346 patients with heterozygous FH we found 20-fold higher incidence rates of early coronary artery disease (CAD) compared to a general population. Yet, clinical disease onset varied greatly in these FH patients. We examined a comprehensive battery of suggested risk factors in these FH patients, and found only factors implicated in the LDL oxidation hypothesis appeared to be associated with CAD risk. We therefore hypothesize that factors related to LDL oxidation (rather that factors unrelated to the inherently high LDL in FH) are the major determinants of CAD risk among FH patients. Our experience from this study and from others suggests that change in repeated carotid intima-medial thickness (IMT) measurements, as opposed to a single measurement, will provide a good index of ongoing atherosclerosis progression and risk related to oxidant stress. Though evidence supports a major role for oxidized lipids in atherogenesis, this has not been critically examined in patients with FH. We propose a 5-year study, now including a vitamin
42
Hypercholesterolemia
intervention component, to determine IMT progression rate among 200 patients with familial hypercholesterolemia. In addition to state-of-the-art IMT determination we will measure coronary calcification by spiral CT, brachial artery flow-mediated dilation, and perform high resolution MR angiography of the carotid tree. Using a random effects model, rate of change of these non-invasive measures of disease burden will be related to previously identified risk factors (including ultracentrifuged lipids and LDL apoB, plasma Lp(a), and total homocysteine) and oxidation-related risk factors (plasma concentration of F2-isoprostanes; susceptibility of LDL to copper-induced oxidation; dietary intake and plasma levels of vitamin E, vitamin C, and carotenoids; as well as plasma platelet-activating factor acetylhydrolase and paraoxonase). Our major hypothesis is that IMT progression will be strongly related to the balance of pro-oxidant and antioxidant factors. The newly added imaging techniques will allow us to compare and contrast results using these endpoints as well. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: PERSONALITY AND HEALTH-- A LONGITUDINAL STUDY Principal Investigator & Institution: Goldberg, Lewis R.; Professor; Oregon Research Institute Eugene, or 97403 Timing: Fiscal Year 2002; Project Start 20-SEP-1997; Project End 31-AUG-2007 Summary: (provided by applicant): The broad objectives of this project are to test the models and mechanisms by which childhood personality traits predict adult healthrelated behaviors, health status and, eventually, mortality. The specific aims are to test three increasingly complex versions of a health-behavior model in which personality traits influence health status through health behaviors, and to evaluate any cultural influences on these models. The participants comprise a cohort of middle-aged adults for whom unique and irreplaceable teacher personality assessments were obtained about 40 years ago. Specifically, 1,770 members of the original population of Hawaiian schoolchildren have been located and 1,055 have been recruited to participate in this longitudinal study of personality and health. The recruited sample is representative of the original population in terms of personality attributes and gender. Over the next five years, information about the participants' personality traits, health behaviors, and health outcomes will be obtained. The personality measures will be based on several different theoretical perspectives including the five-factor framework. Health behaviors will include dietary practices, physical activity levels, and tobacco and alcohol usage. Health outcomes will include objectively assessed physical fitness and flexibility, obesity, and cholesterol level. Assessment methods will include self-reports, reports from knowledgeable others, observer ratings, physical/medical examinations, and laboratory tests. Frequency and appraisals of stressful life events, coping strategies, and constructs from the Theory of Planned Behavior will also be assessed to evaluate the more complex versions of the proposed health-behavior model. The effects on these models of cultural

variables, socioeconomic status, and gender will be examined. The cross-sectional and longitudinal influences of personality traits will be evaluated by bivariate and multivariate linear models and structural equation modeling.

Project Title: PHARMACOGENETICS NETWORK FOR CARDIOVASCULAR RISK THERAPY Principal Investigator & Institution: Krauss, Ronald M.; Senior Medical Scientist; Children's Hospital & Res Ctr at Oakland Research Center at Oakland Oakland, Ca 946091809 Timing: Fiscal Year 2002; Project Start 27-SEP-2001; Project End 31-JUL-2005 Summary: (provided by applicant): The goal of this Pharmacogenetics Research Group is to identify common gene variants that contribute to interindividual differences in response to drugs used to reduce risk for cardiovascular disease (CVD). The Group comprises a multidisciplinary team of investigators with expertise in lipoprotein metabolism and blood pressure regulation; genomics and related computational methodology; clinical trials; human genetics and genetic epidemiology; transgenic mouse models, and database management and biostatistics. For the present study, the drugs chosen are atorvastatin, an HMG CoA reductase inhibitor that lowers plasma lipid levels, and ramipril, an ACE inhibitor that lowers blood pressure. Candidate genes are those with products in metabolic pathways that are potential targets of these drugs. DNA sequence variations in 50 genes will be determined in 24 Caucasians and 24 African-Americans, two ethnic groups with differing degrees of sequence diversity. Based on patterns of single nucleotide polymorphisms (SNPs), haplotypes will be constructed for each gene in both ethnic groups, and groups of SNP genotypes will be identified that are characteristic for the 2-4 most common haplotypes in each gene, present in at least 10 percent of the population. Haplotypes for genes related to atorvastatin effects (27 genes) will be determined in 600 individuals (300 from each ethnic group) who will receive 10 mg/day of this drug for 8 weeks. Haplotypes for genes related to ramipril effects (23 genes) will be determined in 600 individuals (300 from each ethnic group) who will receive 10 mg/day of this drug for 12 weeks. Detailed measurements of phenotypes related to lipoprotein and blood pressure regulation will be performed in the two respective cohorts, and associations will be sought with each of the respective candidate haplotypes. Functional effects of specific sequence variants will be tested in appropriate transgenic mouse models. Future studies will corroborate positive findings using samples from large ongoing clinical endpoint trials of atorvastatin and ACE inhibitor therapy. Data will be transmitted to the Pharmacogenetics Knowledge Base and other genomic databases. The findings will advance our fundamental understanding of the roles of specific genes and their variants in modulating biologic pathways of importance in the pathogenesis and management of CVD.

Hypercholesterolemia
Summary: (provided by applicant): A number of pathophysiological observations in humans and animal models led to the hypothesis that atherosclerosis, a disease of the large arteries that is the primary cause of coronary heart disease (CHD) and stroke, is a multifactorial chronic inflammatory disease in which low plasma levels of HDL and high plasma levels of LDL, are a strong predictor of the condition. LDL oxidation is considered to be an essential process in the development of atherosclerotic lesions. The pro-inflammatory constituents of oxidized LDL are various oxidized phospholipids resulting from the scission and rearrangement of oxidized, unsaturated fatty acids. HDL and HDL-associated enzymes possess anti-atherogenic properties that are due, in part, to their inactivation of oxidized LDL. Although genetic and biochemical studies demonstrated anti-atherogenic role for paraoxanase-1 (PON1), a HDL associated protein, to date, the physiological functions of PON family of proteins; PON1, PON2 and PON3, remain unknown. Based on our preliminary findings, we hypothesize that PON2 and PON3 proteins inhibit the accumulation of oxidized phospholipids in LDL, protect artery wall cells against oxidative stress from reactive oxygen species (ROS) and oxidized phospholipids, and prevent the development of atherosclerotic lesions. In this application, we propose to i) characterize the biochemical and enzymatic properties of PON2 and PON3 proteins, ii) determine cellular localization, products of enzyme activity and the expression levels of PON2 and PON3 proteins in HDL and hyperchloesterolemic animal models, iii) develop transgenic mice and knockout mice to determine the physiological function of PON2 and PON3 proteins as well as the role of PON2 and PON3 in atherosclerosis, and iv) identify and characterize proteins that interact with PON2 and PON3 to delineate the biological substrates of PON2 and PON3 proteins. Understanding the biology and function of the PON proteins will pave way for the discovery of novel therapeutic agents in the fight against atherosclerosis and other inflammatory diseases.

Project Title: PRECONDITIONING IN OPEN HEART SURGERY Principal Investigator & Institution: Maulik, Nilanjana; Associate Professor and Director; Surgery; University of Connecticut Sch of Med/Dnt Bb20, Mc 2806 Farmington, Ct 060302806 Timing: Fiscal Year 2003; Project Start 01-FEB-1998; Project End 31-JAN-2007 Summary: (provided by applicant): The application proposes to continue examining the molecular and cellular mechanisms of ischemic preconditioning (PC). During the current years' funding we demonstrated the role of multiple kinases including receptor tyrosine Idnases and stress-regulated mitogen-activated protein kinases in PC and established an essential role of nuclear transcriptional factor NFkappaB. Our studies also demonstrated that PC potentiates a survival signal by activating several antiapoptotic genes and transcription factors simultaneously blocking the proapoptotic factors leading to the inhibition of apoptosis, which is now showed to independently contribute to myocardial infarction. While, PC has been proven to be the most powerful and state-of-the-art technique for cardioprotection, its clinical applicability is limited. Not only very limited studies exist in the literature to determine if PC could protect diseased hearts, the results are also confusing. We, therefore, propose to study if the cardioprotective abilities of PC are equally applicable to diseased hearts. We selected three most problematic diseased states: cardiomyopathy, hypertension and atherosclerosis which were found relatively less responsive to PC stimulus. We have already established our models to study these diseased hearts. Since adenosine, protein kinase C, protein tyrosine kinase, MAP kinases and KATP channels are the principle

regulators for PC; we plan to determine the status of these factors in the diseased hearts. We anticipate inherent problems in one or more of these factors; and we will attempt to correct the deficiency by exogenous supplementation or by devising means to augment the deficient factors. We also anticipate reduced cardiac defense system in the diseased hearts, which consist of several intraceliular antioxidants and heat shock proteins. Again, we will attempt to precondition these hearts by devising methods to augment these defense elements. Our ultimate objective is to apply the preconditioning modality to protect diseased hearts which are resistant to preconditioning stimulus.

Project Title: REAL-TIME ANALYSIS OF CLATHRIN MEDIATED ENDOCYTOSIS Principal Investigator & Institution: Rappoport, Joshua Z.; Lab/Cellular Biophysics; Rockefeller University New York, Ny 100216399 Timing: Fiscal Year 2003; Project Start 01-AUG-2003; Project End 31-JUL-2006 Summary: (provided by applicant): This project involves the development and application of a system for the real-time analysis of clathrin-mediated endocytosis in living cells utilizing total internal reflection fluorescence microscopy (TIR-FM) TIR-FM represents a microscopy technique capable of selectively imaging events occurring adjacent to the plasma membrane with very high sensitivity. Clathrin mediated endocytosis is responsible for the internalization of activated receptors and ligands, nutrients, and cell adhesion molecules. Several genetic diseases are caused by defects in endocytosis (e.g. familial hypercholesterolemia) and numerous pathogens (e.g. influenza virus) gain entry into cells by exploiting the endocytosis machinery. Although many proteins involved in clathrin mediated endocytosis have been identified, the current techniques for studying endocytosis lack a real-time kinetic analysis of the formation and internalization of individual coated pits and of the interactions among the proteins involved. TIR-FM has the potential to permit analysis of clathrin mediated endocytosis in living cells and allows simultaneous imaging of the proteins involved the formation and fission of clathrin-coated pits under various physiological conditions (e.g. migrating cells, polarized cells and specialized cells).

Project Title: REDOX-ACTIVATION OF VASCULAR STORES OF NO BY VITAMIN C Principal Investigator & Institution: Feelisch, Martin; Molecular and Cellular Physio; Louisiana State Univ Hsc Shreveport P. O. Box 33932 Shreveport, La 71103 Timing: Fiscal Year 2002; Project Start 01-JAN-2002; Project End 31-DEC-2006 Summary: (provided by applicant): Early in atherosclerosis endothelium-dependent relaxation is impaired. The underlying endothelial dysfunction is thought to involve inadequate bioavailability of nitric oxide (NO). Mechanisms that underlie this effect remain uncertain but may include reaction of NO with free radicals and depletion of substrate. Since NO plays a crucial role in atherogenesis, it is important to determine if NO bioavailability can be enhanced. Recent clinical studies suggest that vitamin C (ascorbate) can reverse endothelial dysfunction by enhancing endogenous NO-mediated vasorelaxation. However, the molecular mechanisms underlying this effect are not clearly understood. The current concepts are that ascorbate acts as an antioxidant by either sparing intracellular thiols or by scavenging superoxide radicals produced during an enhanced oxidative stress. Preliminary data presented in this application suggest an alternative hypothesis that encompasses both aforementioned concepts. We propose a
46
Hypercholesterolemia
unique role for ascorbate in the vasculature based on the finding that, in addition to eliciting vasorelaxation, part of the NO produced from endothelial NO-synthase (eNOS) is stored in the tissue in the form of stable NO adducts. While the existence of such tissue stores of NO has been recognized earlier, its potential physiological and clinical implications have not yet been examined. We have observed that ascorbate relaxes vascular aortic rings in vitro by redox-activating tissue stores to release NO. Our preliminary data suggest that NO is bound in endothelial and smooth muscle cells in the form of S-nitrosothiols, which are cleaved by an increase in intracellular reduced glutathione. The intriguing and novel hypothesis built on these observations is that vitamin C reverses endothelial dysfunction by allowing the release of NO from a preformed vascular pooi. Using a combined biochemical/functional approach, the following three specific aims are proposed to address the above hypothesis: 1. To investigate the mechanism of ascorbate induced vasorelaxation and its relationship to the cellular redox status; 2. To identify the chemical nature and localization of NO stores in the vasculature and determine the factors that govern their stability and bioactivation to yield NO; and 3. To investigate the role of ascorbate in the maintenance of vascular homeostasis using different animal models of endothelial dysfunction. Results from these investigations are expected to significantly enhance our understanding of the role of NOS dependent and -independent NO production in endothelial dysfunction. Moreover, they should provide new insight into the actions of ascorbate beyond those of mere antioxidant nature and a rationale for vitamin C supplementation in disease states associated with an enhanced oxidative stress such as hypertension, hypercholesterolemia, and diabetes.

Project Title: REGULATABLE GENE TRANSFER SYSTEM Principal Investigator & Institution: Tsai, Sophia Y.; Professor; Baylor College of Medicine 1 Baylor Plaza Houston, Tx 77030 Timing: Fiscal Year 2002; Project Start 01-SEP-2001; Project End 31-AUG-2003 Summary: Human LDL receptor is expressed primarily in the liver and functions to clear the LDL and cholesterol from the circulation. Mutations of the LDL receptor have been shown to cause hypercholesterolemia which often results in cardiovascular diseases and myocardial infarction at an early age. The goal of this project is to use an inducible system to specifically target the human LDL receptor to the liver in transgenic mice as well as to study the efficacy of using adenoviral vector to deliver this inducible system into cell culture. The inducible system consists of a chimeric transcriptional regulator GLVP and a target gene containing the binding sites recognized by the regulator. In the presence of an inducer, RU486, the regulator binds and activates target gene expression. This inducible system has previously been demonstrated to effectively induce the expression of various target genes in cell culture and transgenic mice up to 5000-fold. To investigate controlled expression of human LDL receptor, we propose to: 1). Generate transgenic mouse target lines containing the human LDL receptor- cDNA; 2). Generate bitransgenic mouse lines capable of expressing the human LDL receptor in response to exogenous ligand; 3). Modify the regulator by substituting the viral activation domain with an activation domain from a human transcription factor to facilitate the future application of this inducible system for gene therapy; 4). Inducible expression of the LDL receptor in cultured cells using adenoviral delivery system. These studies are crucial in providing us with important kinetic data on LDL receptor expression and clearance of serum LDL and cholesterol. We expect that the results from

Project Title: REGULATION OF INTESTINAL CHOLESTEROL ABSORPTION Principal Investigator & Institution: Ostlund, Richard E.; Professor of Medicine; Medicine; Washington University Lindell and Skinker Blvd St. Louis, Mo 63130 Timing: Fiscal Year 2002; Project Start 01-MAY-1994; Project End 31-DEC-2003 Summary: The long-term objective of this project is to reduce coronary heart disease risk through a better understanding of the mechanisms of intestinal cholesterol absorption and the importance of cholesterol absorption in lipid removal of endogenous biliary cholesterol, but surprisingly few studies have actually measured cholesterol absorption in human subjects. Over the last several years this laboratory has developed cholesterol tracers and mass spectrometric methods that allow stable isotopic analysis of cholesterol absorption and metabolism in human subjects at high sensitivity. In this application we exploit these methods to address three important clinical questions. Specific Aim #1 tests the hypothesis that phytosterols (plant sterols) are much more active in reducing cholesterol absorption and LDL cholesterol levels than previously thought. This follows up our interim results which show that sitostanol, without effect in powdered form, has a nearly maximum effect at a dose of less than 300 mg when properly solubilized. Neomycin, an unrelated intra-intestinal cholesterol absorption inhibitor, will be compared to phytosterols and cooking oils with and without natural phytosterols will be examined. Specific Aim #2 tests the hypothesis that oxysterols, including those derived from phytosterols, are absorbed and biologically active. Interim work in rats demonstrated that dietary oxysterols are nearly quantitatively absorbed and also rapidly metabolized. Specific Aim #3 tests the hypothesis that cholesterol absorption is related to chronic dietary cholesterol, dietary fat, and plasma insulin level. Subjects will be fed from the GCRC kitchen and cholesterol absorption measured by isotopic methods. Successful completion of this project will provide new information in areas that have not received sufficient research attention. Knowledge of the importance of phytosterols, oxysterols and dietary determinants of cholesterol absorption will be used in supporting future dietary recommendations and research.

Project Title: REPRODUCTIVE HORMONES AND PRE-CLINICAL CVD IN WOMEN Principal Investigator & Institution: Bairey Merz, C.

Recent randomized trials of hormone replacement therapy (HRT), described below, have failed to demonstrate CVD benefit, and call into question the "estrogen protection" hypothesis. Alternative explanations for the gender gap, e.g., androgen exposure, have not been explored. This application, developed in response to the NHLBI's Innovative Research Grant Program Request for Application HL-01-016 and using existing data sets and biological specimens, is designed to support
48
Hypercholesterolemia
collaborative feasibility research in an innovative and high impact area relevant to CVD in women. The overall aim of this application is to use the existing data and stored blood samples from the NHLBI-sponsored Los Angeles Atherosclerosis Study (LAAS, HL-490-10) to explore new and innovative hypotheses with regard to reproductive hormones and progression of pre-clinical cardiovascular disease (CVD), measured by carotid intima-media thickness (IMT), in the 269 women (45% minority) in the Los Angeles Atherosclerosis Study (LAAS), an ongoing NHLBI-sponsored study of employed utility workers in Southern California without CVD at study entry. Hormonal assays will be performed on stored samples by a NHLBI Reproductive Hormone Core Laboratory, and subsequent analyses will characterize relationships to carotid IMT measured by the LAAS Ultrasound Core Laboratory. The following hypotheses will be test ed: 1) Reproductive hormonal profiles characterized by a relative estrogen deficiency and/or relative androgen excess will be directly correlated with increased baseline carotid IMT and predict greater carotid IMT progression over time in women; 2) Reproductive hormone effects on carotid IMT progression will be observed dominantly in situations of intimal injury, e.g. cigarette smoking, hypercholesterolemia, hypertension or diabetes in women. Innovative aspects of this application include evaluation of reproductive hormones repeatedly and prospectively in women across the spectrum of menopause (pre-, peri- and post-) using innovative methodologies including the sensitive reproductive hormonal assays used in the NHLBI-sponsored Women's Ischemia Syndrome Evaluation (WISE) core laboratory, and a newer quantitative carotid intimal media thickness (carotid IMT) protocol from the NHLBIsponsored LAAS. The current application represents an opportunity to gain feasibility pilot data in the area of the role of reproductive hormones and CVD in women using novel measures and a collaborative approach in order to plan further investigation, if warranted.

Project Title: ROLE OF NO AND ESTRADIOL IN AGING AND ATHEROGENESIS Principal Investigator & Institution: Chaudhuri, Gautam; Professor; Obstetrics and Gynecology; University of California Los Angeles 10920 Wilshire Blvd., Suite 1200 Los Angeles, Ca 90024 Timing: Fiscal Year 2002; Project Start 30-SEP-2000; Project End 31-AUG-2005 Summary: During aging in women, two important changes occur which affect the vascular system. The first is menopause which is associated with estrogen withdrawal and the other is endothelial dysfunction manifested by a decrease in endothelium dependent vasodilation, possibly a reflection of a decrease in NO production by endothelial cells. These two changes may be independent of each other or may be interlinked. We and others have demonstrated that estradiol (E2) increases NO production. Therefore, endothelial dysfunction seen during aging and menopause as manifested by a decrease in endothelium dependent vasodilation and decrease in NO production may be explained just on the basis of E2 withdrawal alone. Estrogen replacement to postmenopausal women has been utilized for potential benefits related to the cardiovascular system. However, the precise mechanism(s) by which estrogens exert a beneficial effect on the cardiovascular system is not known. On the other hand, a recent study indicates that administration of a combination of estrogen and a progestin to women with well-documented coronary artery disease was associated with an increase in the incidence of a second coronary event in the first year of the study compared to the placebo group. In this study, there was no group in which women received E2 alone. Therefore, the role of E2 in modulating atherogenesis, once the

disease is established is not known. Similarly, post-menopausal women are occasionally administered testosterone (t) to increase their sexual function but the effect of T on atherogenesis is not known. The overall hypothesis to be tested is that "the mere withdrawal of E2 or T leads to a decrease in NO synthesis, and thereby, to a proinflammatory response of the vascular wall leading to changes seen early in atherogenesis. A corollary could be that the atherogenic process on the extreme might increase the production of OONO and under such conditions NO inhibition might actually be beneficial." We propose to mimic the postmenopausal state in experimental animals by ovariectomy (OVX). We propose to mimic endothelial dysfunction by pharmacological means by administering animals an inhibitor of NO synthesis. The hypothesis will be tested under three specific aims.

Project Title: ROLE OF SCAVENGER RECEPTORS IN RENAL FIBROSIS Principal Investigator & Institution: Eddy, Allison A.; Professor; Vanderbilt University 3319 West End Ave. Nashville, Tn 372036917 Timing: Fiscal Year 2002; Project Start 01-APR-1992; Project End 31-MAR-2007 Summary: Description (provided by applicant) Progressive renal disease is caused by a process of fibrosis that relentlessly destroys normal renal architecture and function. The number of patients with end-stage renal disease continues to rise exponentially, at an annual cost to Medicare that now exceeds $12 billion. The goal of the proposed studies is to determine how abnormalities of lipoprotein metabolism, which are frequently present in patients with renal disease, contribute to the pathogenesis of renal fibrosis. The overall hypothesis to be tested is that macrophage scavenger receptors process low density lipoproteins that have been oxidatively modified within the kidney to initiate fibrosis-promoting events. It is further hypothesized that this pathway worsens fibrosis in the face of hypercholesterolemia. Three Specific Aims are proposed. (1) To determine the effects of hypercholesterolemia on the severity of renal fibrosis and to delineate the pattern of renal scavenger receptor expression in murine models of renal fibrosis. (2) To investigate the role of the macrophage scavenger receptor class A type I/II (SR-AI/II) and scavenger receptor CD36 in renal fibrosis. (3) To elucidate intrarenal changes in prooxidant and anti-oxidant enzymes that could promote lipoprotein oxidation in murine models of renal disease associated with hyperlipidemia. These in vivo studies will be based on four murine models of renal disease. The functional significance of the two best characterized macrophage scavenger receptors, which are also known to participate in atherogenesis, (SR-AI/II and CD36), will be determined by comparing renal disease severity between wild-type animals and scavenger receptor-deficient animals. Bone marrow transplantation studies will be done to distinguish between the role of renal and macrophage scavenger receptors. Our long-term objective is to provide a scientific basis for the development and use of new therapies for patients with progressive renal disease. It is anticipated that the results of the proposed studies will prove that hypercholesterolemia, intra-renal oxidation of low density lipoproteins and scavenger receptor-dependent interactions with oxLDL represent an important pathogenetic pathway of progressive renal damage.

Hypercholesterolemia
Timing: Fiscal Year 2004; Project Start 01-AUG-2004; Project End 31-JUL-2008 Summary: Considerable evidence supports a role for parasympathetic stimulation in protection of the heart from the genesis of iarrhythmias. A major complication of diabetes mellitus is the development of an autonomic neuropathy which is associated with an impaired response of the heart to autonomic stimulation. The increased incidence of sudden death in diabetic patients, which is exacerbated by hypercholesterolemia and other cardiac risk factors, may be due at least in part to the increased likelihood of arrhythmia in the presence of an impaired parasympathetic response. The long-term goal of this application is to determine a new relationship between sterols, lipid lowering, insulin signaling and the response of the heart to parasympathetic stimulation. In a cell culture model for lipid lowering, in which embryonic chick atrial cells are cultured in medium supplement with lipoprotein depleted serum (LPDS), we have previously demonstrated that lipoprotein depletion results in a marked enhancement of the negative chronotropic response to parasympathetic stimulation and an increased expression of the M2 muscarinic receptor, the alpha-subunit of the heterotrimeric G-protein, Galpha(i2); and the inward rectifying K channel protein, GIRK1, which mediate the response of the heart to parasympathetic stimulation. Based on preliminary data which suggest that the expression of all 3 of these genes might be regulated by the binding of a sterol regulatory element binding protein, SREBP, a transcription factor which regulates cholesterol, fatty acid and glucose metabolism, to a putative sterol regulatory element in their upstream promoters, we will test 4 major hypotheses: 1.) that the expression of M2, Galpha(i2) and GIRK1/GIRK4 in embryonic chick atrial cells is coordinately regulated by SREBP at the level of transcription; 2.) that lipoprotein depletion stimulates M2, Galpha(i2) and GIRK1/GIRK4 expression and the parasympathetic response of the heart by a dual effect on SREBP: an increase in the level of SREBP and a Ras dependent phosphorylation of SREBP and; 3.) that insulin stimulates M2, Galpha(i2) and GIRK1/GIRK4 expression and the parasympathetic response of chick atrial cells via a similar dual effect on the level and phosphorylation of SREBP and; 4.) that SREBP expression regulates parasympathetic responsiveness of the mouse heart and muscarinic stimulation of IKAch in atrial myocytes from these hearts. These studies would support the existence of a new relationship between lipid lowering, insulin function and the parasympathetic response of the heart which could have important implications for the genesis and treatment of cardiac arrhythmias.

Project Title: SMOOTH MUSCLE CELL MEMBRANE DURING ATHEROGENESIS Principal Investigator & Institution: Tulenko, Thomas N.; Professor of Bioc. and Mole. Phar.; Lankenau Institute for Medical Research Wynnewood, Pa 19096 Timing: Fiscal Year 2002; Project Start 01-APR-2000; Project End 31-JUL-2002 Summary: Atherosclerosis continues to be the single leading cause of mortality in Western cultures. The development of atherosclerotic lesions is thought to follow the phenotypic modulation of medial smooth muscle cells (SMC) from the contractile to the synthetic state. A variety of signals have been identified that appear to participate in this modulation including oxidative stress, cytokines and interleukins of macrophage origin and endothelial factors (endothelins and NO.). The primacy of serum hypercholesterolemia as a risk factor suggests that the molecule cholesterol may also play a role in atherogenesis. Work performed by our lab has shown that enrichment of the SMC plasma membrane with cholesterol induces alterations in SMC very similar to those seen in atherosclerosis. Moreover, these alterations are reversed by estrogen. We

hypothesize that enrichment of the SMC plasma membrane with cholesterol is an important factor contributing to SMC modulation during atherogenesis, and that estrogen's ability to reverse this effect contributes to its atheroprotective actions. We will test this hypothesis in 2 aims. Aim l will determine whether cholesterol's ability to alter the SMC membrane bilayer structure, as a single, isolated and independent variable contributes to the phenotypic and gene expression alterations in SMC during atherogenesis. Aim 2 will determine whether the atheroprotective effects of estrogen are mediated A), directly at the level of the arterial SMC and B), whether the mechanism of estrogen's actions are mediated, in part, by countering cholesterol's effects on the arterial SMC membrane. For these studies,we will employ two preparations of vascular cells: 1. early passage (equal to or <3) rabbit aortic SMC, and 2, early passage (equal to or <3) human aortic and coronary artery SMC. Phenotypic alterations will be followed including cell proliferation and collagen synthesis. NFkappaB activation and the generation of reactive oxygen intermediates will be measured as potential signaling intermediates using appropriate techniques. Alterations in gene expression will be assessed by measuring message and protein levels for 2 genes we have identified to be upregulated in SMC during atherogenesis (hn-RNP-K and prolyl-4-hydroxylase) as well as genes identified by others reflecting the synthetic phenotype in SMC, collagens I and III. Combining these approaches will provide essential insights into the cellular basis for the early defects in human SMC during atherogenesis and how estrogen provides cellular protection in this disease Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

This methodology is fat-free and provides a distinct improvement over existing inflexible oil-based strategies that increase the consumer's caloric load. A series of 14-week, double blind placebo controlled trials will examine the effect of formulated sterols on LDL-cholesterol reduction in mildly hypercholesterolemic adults maintained on the American Heart Association Step I diet. Two dosing strategies will be examined. In the first, formulated soy sterols will be dry blended with Instant Breakfast to provide a convenient, once a day dosing regimen. In the second strategy, soy stanols will be delivered in capsules to determine the optimum dose and dosing regimen. Each of these methods will then be tested in subjects who have problems with lipid management. Children who are not candidates for statin therapy because of long-term safety concerns will be enrolled and their LDL-cholesterol reduction monitored while consuming soy sterols in Instant Breakfast. Similarly, adults on statin drugs who have not reached their target LDL-cholesterol level will receive soy stanols in capsules to determine the extent of LDL-cholesterol reduction using this adjunct therapy. Positive results from these studies will provide a safe non-pharmaceutical approach to cholesterol reduction. PROPOSED COMMERCIAL APPLICATION: A new formulation system allows plant sterols and stanols to be effective cholesterol absorption inhibitors in aqueous media. This will be used to determine the reduction in LDL cholesterol when these compounds are incorporated in capsules or a food product.

Project Title: SOY PROTEIN +/- ISOFLAVONOIDS AND PLASMA LIPIDS Principal Investigator & Institution: Lichtenstein, Alice H.; Professor; Medicine; Tufts University Boston Boston, Ma 02111 Timing: Fiscal Year 2002; Project Start 01-AUG-1998; Project End 31-JUL-2005 Summary: The objective of the proposed studies is to assess, in older (40-70 years), hypercholesterolemic [low density lipoprotein (LDL) cholesterol 130-160 mg/dl] male subjects, the impact of consuming different sources of protein (mixed-animal versus soy) and/or different levels of isoflavonoids (primarily genestein and diadzein) on the concentration of plasma lipids [total cholesterol, very low density lipoprotein cholesterol, LDL cholesterol, high density lipoprotein cholesterol, triglyceride] and apolipoproteins (apo) [apo A-1, apo B, Lp (a)]; as well as isoflavonoids in plasma and urine; and hormonal status. The experimental design consists of two multi- phased studies devised to determine the independent effects of type of protein and/or level of isoflavonoids; in Study 1, within the context of a diet approximating that currently consumed in the U.S. [15 energy (E) % protein, 47 E% carbohydrate, 38 E% fat (15 E% SFA, 14 E% UFA, 6 E% PUFA), 170 mg cholesterol/1000 kcal] and Study 2, within the context of a diet consistent with recommendations for individuals with moderate hypercholesterolemia (Step 2 diet) [15 E% protein, 49 #% carbohydrate, 24 E% fat (7 E% SFA, 7 E% MUFA, 8 E% PUFA), 61 mg cholesterol/1,000 kcal]. The variable components of the diets, type of protein and isoflavoniods, will respectively comprise two-thirds (67%) of the protein of 10% of energy, and range from 3 to 49 mg/1000 kcal. The aims of the study are to determine the effect of 1) a one to one (E/E) substitution of soy for mixed-animal protein on plasma lipoprotein, on plasma lipoprotein patterns associated with CHD risk; 3) increasing the isoflavonoid content of the diet in a dose-related manner on plasma lipoprotein patterns associated with CHD risk; 4) dietary protein source on hormonal status (androgens, estrogens, thyroid); and 5) dietary isoflavonoids on hormonal status (androgens, estrogens, thyroid). The area of soy protein and isoflavonoids is highly controversial and in the public domain. The results of these studies, whether positive or negative, should contribute to the data base on which to formulate more specific public health recommendations with respect to decreasing risk of developing CHD.

Project Title: SOY SUPPLEMENTS INTERACT WITH CHOLESTEROL-LOWERING DRUGS Principal Investigator & Institution: Shay, Neil F.; Biological Sciences; University of Notre Dame 511 Main Bldg Notre Dame, in 46556 Timing: Fiscal Year 2003; Project Start 15-MAY-2003; Project End 31-DEC-2004 Summary: (provided by applicant): This project will investigate potential interactions between phytochemical-containing soy extracts and the prescription phamaceuticals, the statins. Statins are a pharmaceutical approach to reducing blood cholesterol levels, and soy supplements are an alternative, botanical approach to to reduce blood cholesterol levels. The long term goal of this research project is to enable individuals and physicians to include soy supplement products as a complementary treatment in addition to prescibing statin intake to reduce blood cholesterol levels. Currently, physicians typically advocate that individuals first use diet to try to reduce cholesterol levels. When a low-fat diet does not reduce cholesterol levels, then physicians will prescribe a cholesterol-lowering drug. Soy has been of interest since it is know that intake of soy reduces cholesterol levels. Nutrition researchers suspect a number of properties of soy

may contribute to its cholesterol-lowering effect. Soy also has a second property, it can enhace the 'cytochrome P450' detoxification system of the liver. The P450 proteins enhance metabolism of organic compounds that enables them to be more easily excreted from the body. P450 proteins metabolize the category of cholesterol-lowering drugs called statins. This project will help determine how soy lowers cholesterol and which liver P450s are activated by soy. It appears that these two actions may simultaneously help and hinder the ability of an individual to lower their cholesterol levels while taking statins. This project will help provide critical information that could enhance the effectiveness of statins, help further lower an individual's cholesterol levels, and perhaps reduce the cost of routine drug therapy often required for those with elevated cholesterol levels. In the future, it may be possible to determine and chemically separate the different components of soy that reduce cholesterol and activate the P450 proteins. If this could be done, it is possible that a specific soy extract product could be produced that has a singular effect that helps lower blood cholesterol levels.

Principal Investigator & Institution: Woollett, Laura A.; Associate Professor; Pathology and Lab Medicine; University of Cincinnati 2624 Clifton Ave Cincinnati, Oh 45221 Timing: Fiscal Year 2002; Project Start 01-APR-1997; Project End 31-MAY-2006 Summary: The acquisition of sterol by the fetus is essential for development and growth. The fetus has two potential sources of cholesterol, de novo synthesis and exogenous sterol. Without the required amount of cholesterol from these sources, the fetus will not survive or will develop abnormally. Data obtained during our previous funding period suggests that the fetus acquires cholesterol from the maternal circulation in addition to that derived from de novo synthesis. The accretion of maternal- derived sterol seems to be dependent upon the sterol balance in the extra-embryonic fetal tissues that protect the fetus from direct contact with circulating maternal constituents, the placenta and yolk sac. Thus, the hypotheses for the present proposal are 1) that the fetus acquires cholesterol from the maternal circulation and 2) that the maternal cholesterol within the fetus is metabolically active. There are 4 specific aims which will test these hypotheses. First, the amount of cholesterol acquired from the maternal circulation will be quantitated. To delineate the processes involved, transport will be examined using different lipoproteins at different stages of development and with varied maternal plasma cholesterol concentrations. The role of specific proteins that have been implicated in fetal development will also be examined in genetically altered animals lacking the proteins in question, such as megalin. Second, the processes involved in the uptake, transport and secretion of cholesterol from the placenta will be evaluated. These studies will be completed in a human derived carcinoma trophoblastic cell line and in human placental perfusions. To examine the processes, we will study the effects of increasing concentrations of lipoproteins (LDL and HDL), cellular cholesterol and lipid acceptors (lipid-poor apoAI and phospholipid vesicles). Third, the effectors of lipoprotein secretion from the yolk sac will be determined in a yolk sac organ culture. Cholesterol and triglyceride concentrations and triglyceride composition will be manipulated in the yolk sacs and the resultant effect this has on lipoprotein secretion will be examined. The role of specific proteins in this process will also be examined. Finally, the processing of proteins involved in sterol balance, the sterol regulatory element binding proteins, and the activation of Sonic hedgehog, a protein involved in patterning of the forebrain, will be studied in fetal tissues that have accrued different

amounts of maternal cholesterol. Based on the results of this proposal, we expect to define new approaches to enhance the presentation of exogenous cholesterol to the developing fetus or embryo. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: STRUCTURE AND FUNCTION OF THE LDL RECEPTOR Principal Investigator & Institution: Blacklow, Stephen C.; Associate Professor; Brigham and Women's Hospital 75 Francis Street Boston, Ma 02115 Timing: Fiscal Year 2002; Project Start 01-FEB-1998; Project End 31-MAR-2007 Summary: (provided by applicant) The long-term goal of this research is to elucidate the detailed mechanistic basis for ligand binding and release by the low-density lipoprotein receptor (LDLR), and to understand signal transduction by structurally related proteins of the LDLR family. The LDLR is the primary mechanism for uptake of cholesterol carrying particles into cells; the genetic disease familial hypercholesterolemia (FH), which affects about 1 in 500 persons worldwide, results from loss-of-function mutations in the LDLR gene. The LDLR also serves as a prototype for a versatile family of cellsurface receptors that participate in a diverse range of biological processes, including lipoprotein uptake, brain development, and Wnt signal transduction. These proteins combine several types of structural units in similar arrangements, such that groups of cysteine rich LDL-A modules precede regions with clusters of epidermal growth factorlike (EGF) modules and B-propeller domains containing conserved YWTD motifs. Each receptor then terminates with a transmembrane segment and a cytoplasmic tail of variable length. Although these receptors carry out a variety of crucial biological functions, the basis for ligand recognition by the ligand binding, LDL-A modules of the LDLR and related receptors remains poorly understood. In addition, the mechanism by which the LDLR releases ligands in the acidic milieu of the endosome, a process intrinsic to the purified receptor and mediated by the EGF-like modules and the YWTD domain, is also unknown. During the next period of grant support we will address these unanswered questions in lipoprotein receptor biochemistry by pursuing the following specific aims: 1. Determine how the ligand-binding modules of the LDL receptor recognize apolipoprotein E (apoE)-containing ligands. 2. Elucidate the mechanism of ligand release by the LDLR at low pH.

Project Title: SURGICAL INTRAMYOCARDIAL ANGIOGENESIS IN A SWINE MODEL Principal Investigator & Institution: Sellke, Frank W.; Professor and Chief; Beth Israel Deaconess Medical Center St 1005 Boston, Ma 02215 Timing: Fiscal Year 2002; Project Start 01-AUG-2002; Project End 31-JUL-2007 Summary: Angiogenesis is a promising new therapeutic modality for the treatment of coronary artery disease (CAD). However, despite impressive results of animal studies from our laboratory as well as others, preliminary clinical use of angiogenic therapy in humans has only resulted in modest if any objective benefit. Patients with end-stage CAD, who represent the population currently targeted by angiogenic therapy, virtually all have advanced endothelial dysfunction that results in abnormal production and response to endothelial substances. Since angiogenic growth factors operate in large part through the release of endothelial-derived nitric oxide via the activation of tyrosine kinase receptors, the observed failure of effect in patients with end-stage CAD may relate to a deficiency in the stimulated release of these endothelial-derived substances.

This research proposes to define the role of endothelial function on the effects of exogenous growth factor therapy and on the endogenous angiogenic response to myocardial ischemia. To this end, a hypercholesterolemic porcine model will be used that recreates myocardial microcirculatory changes similar to those encountered in humans with CAD. Several study groups that include animals with normal, dysfunctional, or pharmacologically- treated endothelium will be created, in which surgical induction of chronic myocardial ischemia and implantation of sustainedrelease growth factor devices (FGF-2, VEGF, or placebo) will be performed. In each study group, endothelial responses will be assessed in vitro on microvascular reactivity studies, and the angiogenic response will be quantitatively determined at the functional, microvascular, histological, and molecular levels, using tools such as isotope-labeled microsphere assays of myocardial perfusion, sonomicrometry, immunocytochemistry and real time PCR analysis. By clarifying the role of the endothelium and endothelialmodulating agents in the functional angiogenic response, the findings from this research will lead to a more complete understanding of therapeutic angiogenesis, and may allow for the development of this modality towards a safe, effective, and attractive option for the treatment of CAD.

Project Title: TETRAHYDROBIOPTERIN: REGULATOR OF ENDOTHELIAL FUNCTION Principal Investigator & Institution: Katusic, Zvonimir S.; Professor; Mayo Clinic Coll of Medicine, Rochester 200 1St St Sw Rochester, Mn 55905 Timing: Fiscal Year 2002; Project Start 01-DEC-1994; Project End 31-MAR-2005 Summary: (Verbatim from the application): Cardiovascular diseases, including atherosclerosis, remain a leading cause of death and disability in the United States. Nitric oxide is a key regulator of vascular tone, platelet aggregation, white blood cell adhesion, and smooth muscle cell proliferation. Nitric oxide has also been recognized as a critical mediator of angiogenesis. Endothelial dysfunction due to decreased production of nitric oxide is an early event believed to play a major role in initiation and progression of atherosclerosis. Tetrahydrobiopterin (BH4) is an essential cofactor needed for enzymatic activity of nitric oxide synthase. BH4 plays a key role in the control of endothelial nitric oxide production. The general hypothesis of this proposal is that during development of atherosclerosis, up-regulation of BH4 biosynthesis is an adaptive response designed to preserve biosynthesis of nitric oxide and protect the vascular wall from oxidative stress. To test this hypothesis we propose studies with the following specific aims: (1) determine the effects of oxidative stress on vascular BH4 metabolism, (2) characterize the relationship between BH4 metabolism and endothelial dysfunction in arteries exposed to hypercholesterolemia in vivo, and (3) analyze the role of superoxide anion in BH4 metabolism and endothelial dysfunction in murine models of atherosclerosis. Apolipoprotein E (ApoE)-deficient mice and low-density lipoprotein (LDL) receptor-deficient mice develop spontaneous hypercholesterolemia and atherosclerosis with many features that are characteristic of lesions in humans. Preliminary findings indicate that endothelial dysfunction, as reflected in impaired endothelium-dependent relaxations, is present in murine models of atherosclerosis. The exact mechanism responsible for endothelial dysfunction induced by hypercholesterolemia is not understood. Initial analysis performed on isolated aorta of ApoE-deficient mice indicated that increased production of superoxide anions in the vascular wall plays a major role in inactivation of endothelial nitric oxide. However, the effects of superoxide anions and oxidative stress on BH4 metabolism have not been

studied. To characterize the role of superoxide anion in BH4 metabolism and endothelial dysfunction, arteries from superoxide dismutase (SOD) transgenic mice and SODdeficient mice will be studied. Overexpression of SOD in ApoE-deficient mice will be used to protect BH4 from superoxide anion-induced oxidative stress and rescue endothelial dysfunction. Double knockout ApoE-SOD-deficient mice will be created to determine whether increased production of superoxide anion accelerates oxidation of BH4 and impairment of endothelium-dependent relaxation. It is anticipated that the results of the proposed experiments will provide novel and important information concerning the effect of oxidative stress on vascular BH4 metabolism and the pathogenesis of atherosclerosis. This information may help to develop new therapeutic interventions designed to prevent endothelial dysfunction and progression of atherosclerosis.

Drew University of Medicine and Science (Drew). This center, entitled "The Center of Urban Research and Education in Diabetes and Metabolism" (CUREDM), is designed to attract an established research investigator with independent research support and provide research resources for investigators who will study diabetes, insulin resistance states, hypercholesterolemia, obesity, hormonal dysregulation and other metabolic related diseases. These resources will include the development of two core facilities complemented by a developmental project. CUREDM will augment and strengthen Drew's clinical research capabilities through its independent research and its ability to mentor junior investigators. Consistent with the request for this application CUREDM will address health care issues that disproportionately affect the indigenous populations served by the RCMI institutions and are recognized as national health care priorities. The unique patient population at Drew University is comprised of approximately 55 percent Hispanic, 35 percent African Americans, and 10 percent Asian/Pacific Islander who suffer disproportionately from diabetes and metabolic related disorders. Over the last 4 years Drew has experienced a progressive enhancement in the clinical research infrastructure and an increasing number of investigators with research interest and activity in diabetes and metabolic related diseases. This creates an appropriate environment of professional interaction and growth that will facilitate the recruitment of a highly qualified investigator to direct CUREDM. Thus, Drew is an ideal location for the establishment of CUREDM. Although there is a particularly high prevalence of diabetes and metabolic disorders in underserved populations, these disorders are pervasive in our society and information gained from CUREDM is likely to yield important contributions toward improving health care for the nation.

Project Title: THE CHEMOKINE RECEPTOR CXCR-2 IN ATHEROSCLEROSIS Principal Investigator & Institution: Boisvert, William A.; Assistant Member; Scripps Research Institute Tpc7 La Jolla, Ca 92037
Studies
57
Timing: Fiscal Year 2002; Project Start 01-SEP-1999; Project End 31-AUG-2003 Summary: (Adapted from Investigator's Abstract): Multiple mechanisms operate to promote macrophage accumulation within the atherosclerotic intima. This proposed work stems in part from observations by others, including the finding that in apoE knockout mice which are deficient in the MCP-1 receptor CCR2, atherosclerosis is diminished, but lesion size and complexity still progress from 5-13 weeks. Also monocyte CCR2 expression in vitro is attenuated by several inflammatory mediators which can be in the plaque, or by differentiation to macrophages. They therefore propose that other mechanisms are at play in promoting macrophage retention and expansion within the atherosclerotic lesions. Base on their previous work, they have found that intimal macrophages express the chemokine receptor CXCR2, and the CXCR2 ligands, GROalpha, and IL-8. Initial data also indicate that leukocyte deficiency of the mouse CXCR2 homologue, mIL-8RH, arrested progression of early macrophagerich lesions and decreased retention of lesion macrophages. They therefore hypothesize that specific CXCR2 effects mediate the intra-lesional growth, inflammatory differentiation and activation of recruited macrophages. Their specific aims are as follows: Define the sequence of atherogenic events mediated by CXCR2, using two animal model systems. They will first transplant irradiated LDLR-/- mice with bone marrow from mIL-8/ CXCR2-/- or control mice under gnotobiotic conditions. Mice will be fed a chow or high cholesterol diet to define the role of mIL-8RH in mild vs. severe hypercholesterolemia-induced atherosclerosis. Second, to assess the role of mIL-8RH in cells other than leukocytes, they will study LDLR-/-, mIL-8RH-/- mice derived by crossbreeding. Early monocyte ingress, fatty streak formation, and lesion progression will be studied in both groups at 3 to 30 weeks. They will concurrently detect lesion mIL-8RH and macrophage markers including MOMA2 in each group of mice. They will also compare temporal and spatial macrophage accumulation, expression of mIL-8RH, KC/GROalpha, JE/MCP-1 and CCR2, the appearance of oxLDL epitopes and lipid deposition. Test the hypothesis that CXCR2 expression acts by promoting macrophage retention in early atherosclerotic lesions, and does so in part by increasing macrophage beta1 integrin-mediated adhesion. First they will determine if retention of lesion monocytes is greater in LDLR-/-, mIL-8RH+/+ than LDLR-/-, mIL-8RH-/- mice. To do so they will isolate, label (using [3H]-glycerol) and infuse bone marrow monocytes into LDLR-/- mice on a high fat diet. Migration and retention of labeled monocytes in vivo will be measured in aortic lesions at 2,4,7, and 14 days post infusion. They will then test the hypothesis that the generalized cell culture adhesion defect of macrophages from mIL-8RH-/- mice is associated with decreased activation of beta1 integrins, which bind fibronectin (VLA-4, VLA-5). They will also study CXCR2-mediated effects on adhesion of human peripheral blood monocytes using specific neutralizing antibodies for integrins and integrin ligands. They will also test the hypothesis that macrophage CXCR2 expression is necessary for macrophage matrix invasion. Test the hypothesis that CXCR2 expression, via effects on macrophage adhesion, mediates macrophage differentiation to a distinct, pro-atherogenic inflammatory phenotype. Here they will further study human peripheral monocyte-derived macrophages and mouse wild type and mIL-8RH-/- bone marrow derived macrophages under conditions where CXCR2 is normally expressed in vitro. They will specifically look at the effects of the CXCR2 ligands, GROalpha, and IL-8 on macrophage proliferation and expression of JE/MCP-1. They will also determine if CXCCR2-mediated adhesion modulates the production of apoE, oxidation of LDL, and accumulation of cholesteryl ester. Finally based on the results of Specific Aim 2, they will test the hypothesis that VLA-5, and VLA-4 activation, via stimulation by CXCR2 ligands, regulate one or more of these activities. They will also correlate these results with the features of the mouse atherosclerotic lesions of

Project Title: THE ROLE OF NITRIC OXIDE IN CHOLESTEROL HOMEOSTASIS Principal Investigator & Institution: Ihrig, Melanie M.; Brigham and Women's Hospital 75 Francis Street Boston, Ma 02115 Timing: Fiscal Year 2002; Project Start 01-APR-2002; Project End 31-MAR-2007 Summary: (provided by applicant) Cholesterol homeostasis is maintained by balancing intestinal absorption, endogenous biosynthesis, hepatic uptake and biliary secretion of cholesterol and bile acids. Recently, there has been a renewed interest in the role of intestinal cholesterol absorption in cholesterol homeostasis. A number of studies have assessed the effect of reduced small bowel transit time on cholesterol absorption, and each found a significant correlation between transit time, cholesterol absorption and serum cholesterol concentration. We have demonstrated that mice with a targeted mutation in the inducible nitric oxide synthase (iNOS) gene have elevated serum cholesterol levels. Each of three unique isoforms of NOS is expressed in different cell types and under different conditions throughout the gastrointestinal tract. There is considerable evidence that nitric oxide (NO) produced in the gastrointestinal tract influences enteric myoelectrical activity, coordinates peristalsis and ultimately affects intestinal transit time. Nitric oxide acts as an inhibitory neurotransmitter, and as a vasodilator in the intestinal tract. Additionally, enteric pathogens, and the experimental administration of lipopolysaccharide (LPS), elicit excessive production of NO through transcriptional upregulation of iNOS. Thus, NO concentrations in the intestinal tract wax and wane depending on the immediate circumstances. A plausible explanation for the increased serum cholesterol levels observed in the iNOS-deficient mice, then, is delayed small bowel transit time, brought on by perturbation of the regulation and coordination of intestinal motility. Aberrant cholesterol homeostasis is a risk factor for both atherosclerosis and cholesterol gallstone formation. In addition to hypercholesterolemia, we observed aortic atheromas in the iNOS-deficient mice. Prolonged intestinal transit time augments formation of cholesterol gallstones, and if prolonged intestinal transit time is the underlying cause of hypercholesterolemia in iNOS-deficient mice, the manifestation of atherosclerosis and cholelithiasis may well be linked. The proposed studies will explore these possibilities in iNOS-deficient mice under various experimental conditions. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: THYROID HORMONE RECEPTOR Principal Investigator & Institution: Baxter, John D.; Professor and Director of Medicine; Metabolic Research Unit; University of California San Francisco 500 Parnassus Ave San Francisco, Ca 941222747 Timing: Fiscal Year 2002; Project Start 01-AUG-1989; Project End 31-MAR-2007 Summary: Nuclear receptor genes comprise a large family and encode receptors for thyroid and steroid hormones, vitamin D, retinoids, prostaglandins, and other ligands. These receptors regulate most human processes and are important pharmaceutical targets. The receptors contain amino-terminal, DNA-binding and ligand-binding (LBD) domains. Ligand-induced receptor conformational changes induce receptor activities that regulate transcription. Receptors mediate effects through interactions with other proteins, including coactivators and heterodimerizing partners. Central to

understanding receptor actions is knowing their atomic structures. The Principal Investigator and colleagues first solved the X-ray structure of a liganded nuclear receptor LBD, that of the thyroid hormone receptor- alpha (TRalpha) that revealed insights into receptor function, and subsequently solved other structures, including TRalpha LBD bound to several ligands, human (h) TRbeta bound to agonists, including one that is TRbeta-selective, hTRbeta bound to a coactivator peptide and mutated hTRbeta forms that cause thyroid hormone resistance. These structures have revealed more information about receptor function, have been useful for designing a ligand that selectively modulates hTRbeta bound to a coactivator peptide and mutated hTRbeta forms that cause thyroid hormone resistance. These structures have revealed more information about receptor function, have been useful for designing a ligand that selectively modulates hTRbeta thyroid hormone response sand may be a prototype drug for treating obesity and hypercholesterolemia, and for designing thyroid hormone antagonists that may be prototypes for treating hyperthyroidism. In the proposed studies it is planned to determine the X-ray crystal structure of the hTRbeta PBD bound to several different ligands that perturb the structure in different ways, hTRbeta complexed with a retinoid X-receptor (RXR) heterodimerizing partner, and liganded hTRbeta LBD complexed with a novel coactivator peptide and a cyclized high affinity binding coactivator peptide. It is also planned to determine X-ray structures of RXR and TR DBD-LBD proteins and the full-length TR. The new structures should provide information about hormone-induced conformational changes, mechanisms of receptor interaction with other protein, the multiple receptor domains, and relations between domains. The results should yield insights into TR function and how ligands act as agonists or antagonist, are applicable to nuclear receptors in general, and may facilitate pharmaceutical design.

Project Title: TRANSCAPILLARY FLUID EXCHANGE Principal Investigator & Institution: Granger, D. Neil.; Boyd Professor and Head; Molecular and Cellular Physio; Louisiana State Univ Hsc Shreveport P. O. Box 33932 Shreveport, La 71103 Timing: Fiscal Year 2002; Project Start 01-DEC-1986; Project End 31-MAY-2004 Summary: Hypercholesterolemia, an established risk factor for ischemic diseases of the heart, brain, liver and other tissues, appears to alter the function of both circulating blood cells and microvascular endothelial cells. Recent evidence in the literature and from our laboratory indicates that hypercholesterolemia profoundly exaggerates the microvascular dysfunction, inflammatory cell infiltration, and cellular necrosis associated with reperfusion of ischemic tissues. The work proposed in this application will extend our effort to define the mechanisms that underlie these exaggerated responses to ischemia/reperfusion (I/R) in hypercholesterolemic animals. We propose to assess the contributions of lymphocytes, platelets, and enhanced oxidant production to the leukocyte-endothelial cell adhesion, capillary malperfusion, tissue hypoxia, cytokine production, and cellular necrosis observed in an established model of I/R induced liver injury. Wild-type and LDL-receptor knockout mice with normal and elevated serum cholesterol levels will be studied. Intravital fluorescence microscopy will be used to monitor the number of perfused sinusoids and the accumulation of total leukocytes, lymphocytes, and platelets in liver sinusoids and hepatic venules after I/R. NADH autofluorescence will be monitored as an index of oxidative stress (tissue hypoxia) while the oxidation of dihyrorhodamine 123 will be used to monitor oxidant production. Plasma levels of liver enzymes will be used to assess hepatocellular injury,

while a radiolabelled monoclonal antibody technique will be used to quantify the expression of P-selectin in the liver vasculature. One specific aim will focus on the influence of varying durations of ischemia, followed by reperfusion on the microvascular accumulation of total leukocytes, lymphocytes (T- and B-cells), and platelets in the postischemic liver of normal and hypercholesterolemic mice. A second specific aim will focus on the contributions of lymphocytes and platelets to the exaggerated responses of the liver microvasculature to I/R. SCID mice, reconstituted with specific lymphocyte populations from wild-type and mutant mice, will be used to address the role of lymphocytes in I/R-induced liver injury. Platelet-directed interventions (including neutralizing antibodies and mutant mice) will be used to assess the contribution of platelet accumulation. A third specific aim will determine whether the accumulation of these inflammatory cells and subsequent tissue injury is linked to an enhanced production of oxidants in hypercholesterolemic mice. Different mutant mice and oxidant-directed reagents will be used to assess the contribution and source of oxidants in normal and hypercholesterolemic mice. The results obtained from the proposed studies should lead to an improved understanding of the mechanisms by which hypercholesterolemia exacerbates ischemic tissue injury.

Project Title: TRANSCRIPTIONAL ANALYSIS OF POLLUTANT EXPOSURE Principal Investigator & Institution: Shohet, Ralph Victor.; Professor; Internal Medicine; University of Texas Sw Med Ctr/Dallas Dallas, Tx 753909105 Timing: Fiscal Year 2004; Project Start 01-AUG-2004; Project End 31-JUL-2007 Summary: (provided by applicant): The overall objective of this application is to better understand the molecular mechanism of cardiovascular disease that are modified by environmental pollutants. The investigator's models of environmental toxicity will be diesel and gasoline emissions. The underlying hypothesis of this work is that transcriptional regulation in response to these emissions will identify genes that are important in the development of pollution-related cardiovascular disease. Their primary goal is to determine the transcriptional response to complex emissions and the secondary goal is to evaluate any synergistic effect of hypercholesterolemia on this process. Thus, this project will have two specific aims: Specific Aim 1: To define the transcriptional response to whole-exhaust emissions in monocytes and endothelial cells in vivo. The investigators hypothesis is that the different chemical make-up of diesel exhaust and coal emissions will elicit varied transcriptional responses in endothelial cells and monocytes. They will conduct exposures at two concentrations and with both acute (3 day) and chronic (6 week) duration. Specific Aim 2: To determine the interaction of hypercholesterolemia with inhaled pollutants on gene regulation in these cells. The hypothesis is that whole exhaust will elicit transcriptional pathways relevant to the formation of atherosclerotic vascular disease, and that these effects will be more substantial in a susceptible model. The investigators will therefore expose control and ApoE -/- mice, on a atherosclerotic diet, to low levels of whole exhaust for 6 weeks. The investigators will use thorough transcriptional analysis to identify genes that are regulated in response to emission, in a novel mouse model that permits assessment of in vivo endothelial responses. They expect that these studies will generate an understanding of the mechanism of exhaust-related cardiovascular morbidity and identify the most important components of whole exhaust that cause such morbidity. They further anticipate that these insights will enhance our understanding of vascular pathology and potentially direct efforts at reducing the toxicity of combustion exhaust.

IN
Principal Investigator & Institution: Chawla, Ajay; Medicine; Stanford University Stanford, Ca 94305 Timing: Fiscal Year 2004; Project Start 01-APR-2004; Project End 31-MAR-2009 Summary: Our long-term goal is to understand how lipids regulate gene expression in vascular cells, and how these pathways contribute to the pathogenesis of coronary artery disease. Epidemiologic studies have clearly established the pathogenic link between dyslipidemias, such as hypercholesterolemia and hypertriglyceridemia, and the development of atherosclerotic heart disease. Intensive research in understanding the biochemical modifications that confer pathogenicity to the LDL particles has elucidated the molecular route through which oxLDL regulates gene expression in lesional macrophages and contributes to the development of vascular disease. However, the molecular and cellular responses to triglyceride-rich lipoproteins, such as VLDL, remain poorly understood. Our previous studies have identified a transcriptional pathway in macrophages that is driven by VLDL through the activation of PPAR delta. Interestingly, these studies revealed that the fatty acids that are present in VLDL particle can potently transactivate the PPAR delta receptor. Consistent with this, treatment of wild type, but not PPAR delta null, macrophages with the VLDL particle resulted in transcriptional induction of target genes. The studies proposed in the present grant application will take molecular, cellular, and genetic approaches to further investigate how PPAR gamma and delta orchestrate the macrophage response to incoming fatty acids. Data from these studies will greatly enhance our understanding of the how these receptors regulate macrophage homeostatic responses in both physiologic and pathophysiologic conditions, and potentially lead to the identification of new therapeutic targets to treat this chronic disease. The specific aims of this proposal are to: 1) Determine the pathways by which PPAR gamma controls macrophage fatty acid metabolism, 2) Assess the regulatory role of PPAR delta in the utilization of fatty acids by macrophages, and 3) Determine the molecular mechanisms by which PPAR delta regulates macrophage inflammatory response.

Project Title: TRANSGENIC RAT MODELS OF ALZHEIMER'S DISEASE Principal Investigator & Institution: Herrera, Victoria Lm.; Associate Professor; Medicine; Boston University Medical Campus 715 Albany St, 560 Boston, Ma 02118 Timing: Fiscal Year 2002; Project Start 15-FEB-2000; Project End 31-JAN-2004 Summary: Animal models are proven investigative tools for study of complex human diseases such as Alzheimer s Disease (AD) and atherosclerosis. Trangenic and bigenic mouse models for presenilin-1 (PS1) and amyloid precursor protein (APP) human gene variants have been instrumental in delineating their roles in AD pathogenesis. However, to date these mouse models have not exhibited key AD pathology such as neurofibrillary tangles, neuronal loss and AD-associated cognitive/neurobehavioral deficits. We hypothesize that a more phenotypically robust and experimentally accessible model of Alzheimer s disease will be obtained in the rat based on key observations: a) rat ApoE is more homologous to human ApoE4 compared with mouse; b) rat complement, like the human has greater levels compared with the mouse and might be a key determinant to the development of neurofibrillary tangles; c) neurobehavioral studies assessing aging and hippocampal-specific learning and memory deficits have been validated in the rat; d) the size of the rat allows lesioning and

imaging studies; f) the more robust atherosclerotic phenotype in transgenic rats compared with mice given the same human cholesteryl ester transfer (hCETP) transgene indicates valid modeling for complex diseases. This proposal focuses on the following specific aims. (1) Develop three key inbred Fischer 344 rat AD models with the highest probability for a robust AD phenotype: a) homozygous high-expresser of mutant human APPSWE AD gene, TgAPP, b) homozygous bigenic with both mutant human PSIM146L and hAPPSWE, 2TG[PS1xAPP], and a trigenic rat model, 3Tg]PS1 x APAP x hCETP], which imposes, if not test, hypercholesterolemia-induced exacerbaytion of amyloidogenic APP processing in vivo. (2) Investigate the degree of cognitive deficits in the combinational transgenic rat AD models by measuring hippocampal-dependent working memory and spatial learning and memory at 12, 18, 24 months. 3) Correlate observed hippocampal-dependent neurobehavioral alterations with AD- associated neuropathological alterations at 12, 18, and 24 months. (4) Correlate key neurobehavioral and neuropathological alterations with molecular and cellular markers of AD pathogenesis at 12, 18, and 24 months. Comparative analysis of the proposed rat models will not only address an accessible AD model for mechanistic dissection and therapy development, but also provide insight into the role of complement- and hypercholesterolemia-mediated disease paradigms in AD pathogenesis.

Project Title: VALIDATION OF ADHERENCE DATA--USE IN CLINICAL PRACTICE Principal Investigator & Institution: Pladevall, Manel; None; Case Western Reserve Univ-Henry Ford Hsc Research Administraion Cfp-046 Detroit, Mi 48202 Timing: Fiscal Year 2003; Project Start 05-AUG-2003; Project End 31-JUL-2006 Summary: (provided by applicant): Non-Adherence to medications is a common problem in clinical practice especially among patients with asymptomatic chronic conditions like type II diabetes and hypercholesterolemia in whom some 50% of patients are non-adherent. The costs of poor adherence to medications have been estimated to approach $100 billion dollars a year and are the result of adverse outcomes such as hospitalization, the development of complications, disease progression, premature disability or death. Non-Adherence is the result of a complex interaction among the social environment, the patient and the health providers. Adherence to medications is not routinely measured in clinical practice and a gold standard that can be easily implemented even for research purposes does not exist. Yet, the use of claims data to measure adherence has been shown useful and, given the relatively small costs associated with its use, its implementation in routine clinical practice appears both feasible and sustainable. However, more information is needed on the validity of the method and on the consequences of making adherence information available to both patients and physicians. Using The Chronic Care model as a theoretical framework, we propose a two-phase study. In Phase I, claims data will be used to identify diabetic patients receiving pharmacological treatment for both diabetes and hypercholesterolemia and to measure their A to medications prescribed for the two conditions. The association between adherence indices and intermediate outcomes (glycosylated hemoglobin and cholesterol levels) will be estimated. In Phase II, qualitative (focus groups) and quantitative methods (telephone and mail surveys) will be used to examine patients' attitudes, beliefs, barriers, relationship with providers, and stages of change towards adherence and towards the introduction of adherence information in clinical practice in conjunction with the Health Belief and Stages of Change Models as explanatory theories. The study will help clarify the association

between adherence and clinical outcomes as well as to estimate the predictive and convergent validity of prescription claims data as a method of measuring adherence to medications. Finally, we will explore intrinsic factors at the patient level related to adherence, and patient and provider preferences and attitudes towards the use of adherence information in routine clinical practice.

Project Title: VASCULAR RISK FACTORS IN ALZHEIMER'S DISEASE Principal Investigator & Institution: Li, Gail; Psychiatry and Behavioral Scis; University of Washington Grant & Contract Services Seattle, Wa 98105 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-AUG-2007 Summary: (provided by applicant): Candidate's Plan/Training: The Candidate plans a career as a patient-oriented clinical research investigator and academic geriatric psychiatrist bridging dementia, vascular risk factors and clinical epidemiology. Training will include formal didactics in lipid metabolism and augmentation of the Candidate's previous epidemiology training with additional advanced biostatistics and epidemiology courses and closely supervised completion of the research plan. Environment: The University of Washington Alzheimer's Disease Patient Registry (ADPR)/Adult Changes in Thought (ACT) and Alzheimer's Disease Research Center (ADRC) provide expertise in epidemiology, clinical dementia evaluation, and biostatistics to form an ideal research environment for epidemiological investigation of Alzheimer's disease (AD) and related dementias. Research: Recent studies suggest midlife hypercholesterolemia and hypertension increase risk of dementia and specifically AD in late life. Cholesterol-lowering medications, the 3-hydroxy-3-methylglutarylcoenzyme-A reductase inhibitors, i.e., statins, may reduce the risk of AD. We hypothesize that vascular risk factors increase the risk of AD and/or vascular dementia (VaD) and use of statins reduces this risk. To address these hypotheses, Specific Aim 1 will determine whether the use of statins decreases the risk of AD and/or VaD, and whether these effects are modified by the presence of the Apolipoprotein Ee4 allele. We also investigate whether high serum low-density lipoprotein (LDL) and low serum highdensity lipoprotein (HDL) are associated with increased risk for AD and/or VaD. Specific Aim 2 will determine if hypertension in older age (> 65 years) increases the risk of AD and/or VaD; we will also investigate blood pressure changes prior to the diagnosis of AD and/or VaD. A prospectively enrolled community-based cohort of 2581 initially cognitively normal elderly will provide the framework for this study. Results from the research project will provide insights into vascular risk factors for AD, thus providing additional information toward development of new prevention and treatment strategies. This research plan, together with the didactic and mentored instruction proposed, will provide the career development necessary for the candidate to conduct scientifically rigorous, independently funded, patient-oriented research.

The nature and complexity of lesion development in atherosclerosis suggest that the disease
64
Hypercholesterolemia
may have several etiologies. The generation of free radicals is associated with alterations in both vascular reactivity and lipoprotein metabolism. The studies proposed in this application are designed to provide new information concerning oxidant-induced damage in the vessel wall. It is hypothesized that impaired blood vessel function in hypercholesterolemic rabbits is due to the modification of nitric oxide (NO) by superoxide anion (O2-), leading to the production of the potent oxidant peroxynitrite (ONOO-). Reactive oxygen species are generated under normal physiological conditions, with native antioxidant scavengers minimizing oxidant-mediated injury. An imbalance in antioxidant defense mechanisms and changes in cellular metabolic processes then contributes to the development and progression of atherosclerotic disease. The studies outlined in this application are designed to provide new information describing the cellular mechanisms involved in these free radical reactions, namely that free radical injury in blood vessels of hypercholesterolemic rabbits is linked to the binding and concentration of xanthine oxidase (XO) at glycosaminoglycan (GAG) sites on the surface of endothelial cells and in the interstitial space. The hypothesis to be tested in this application is that GAG-bound XO is an important source of O2-, thus ONOOformation, and contributes to the oxidative component of hypercholesterolemia. GAG function or expression may be altered by hyperlipidemia, thereby facilitating incorporation of lipoproteins in the vessel wall as well as serving as a site for XO binding and incorporation, influencing changes in the vasculature and playing an important role in the pathological events associated with hypercholesterolemia.

Project Title: XANTHINE OXIDASE MODULATION OF CELL OXIDANT PRODUCTION Principal Investigator & Institution: Tarpey, Margaret M.; Associate Professor; Anesthesiology; University of Alabama at Birmingham Uab Station Birmingham, Al 35294 Timing: Fiscal Year 2002; Project Start 01-FEB-2001; Project End 31-JAN-2005 Summary: (Adapted from the Applicant's Abstract): The endothelium serves as a critical component in the maintenance of vascular homeostasis. Alterations in endothelial cell production of oxidants contribute to defective vascular function and are implicated in the pathogenesis of diverse vascular diseases. However, the tissue sources of enhanced vascular cell oxidant production and the sites of oxidant action have not been determined with certainty. Recently, recognition of a) elevated plasma levels of circulating xanthine oxidase activity in diverse disease processes (sepsis, hypercholesterolemia, post- liver transplantation) and b) the ability of xanthine oxidase to specifically bind to endothelium with resultant increases in intracellular xanthine oxidase activity provide potential mechanism(s) by which non-endothelial cell-derived xanthine oxidase could contribute to endothelial oxidant production. While enhanced production of superoxide can diminish nitric oxide bioavailability by virtue of its reaction with nitric oxide and thus, concomitantly yield secondary oxidants, the potential for superoxide and other cellular oxidants to directly modify the activity of endothelial nitric oxide synthase has not been fully explored. From this foundation of understanding, it is hypothesized that increases in cell-associated xanthine oxidase modulate endothelial-dependent vascular function. To address this hypothesis, the following Specific Aims will be pursued: 1) Characterize vascular cell interactions with circulating xanthine oxidase. The kinetics of cell binding and uptake of circulating xanthine oxidase/dehydrogenase will be determined. In addition, xanthine oxidase

circulating and ultimate tissue distribution will be defined in vivo. 2) Explore the impact of elevated xanthine oxidase-derived products (reactive species, uric acid) on expression and activity of endothelial nitric oxide synthase. The effects of xanthine oxidase on transcription and translation of endothelial nitric oxide synthase will be ascertained as well. The vascular functional consequences of increased xanthine oxidase activity will also be determined. Upon successful completion of the proposed aims, a) the contribution of xanthine oxidase to endothelial cell oxidant production will be better defined, b) detailed mechanistic information will be available regarding the presence, reactions and regulation of specific oxidative pathways that modulate endothelial nitric oxide synthase expression and activity and c) new insight will be gained for prospectively devising mechanism-directed pharmacologic strategies.

Project Title: ZEBRAFISH ASSAY FOR CHOLESTEROL AND LIPID LOWERING DRUGS Principal Investigator & Institution: Rubinstein, Amy L.; Director of Research; Zygogen, Llc Kell Hall 520 Atlanta, Ga 303033003 Timing: Fiscal Year 2003; Project Start 15-JUN-2003; Project End 31-MAY-2004 Summary: (provided by applicant): High levels of low density lipoprotein (LDL), cholesterol and triglycerides have been associated with an increase in cardiovascular disease. Drugs such as cholesterol-lowering statins and triglyceride-lowering fibrates have led to a reduction in coronary heart disease. Although current drugs have enjoyed some success, a need exists for improved lipid management and reduced side effects. Zygogen is developing a novel in vivo approach to identifying potential lipid-lowering drugs using Zebrafish, called Z-Lipotrack. Lipid processing is highly conserved in the Zebrafish. Because Zebrafish larvae are essentially transparent, lipid processing can be readily observed in the whole organism, with the aid of fluorescent lipid reporters. The goal of the proposed research is to develop Z-Lipotrack technology for use in high throughput compound screening, with the ultimate aim of discovering better drugs for lowering lipid levels. The proposed work will validate Z-Lipotrack as a compound screening tool. This includes testing additional control compounds, characterizing compounds identified in a small but diverse library of marketed drugs, and quantifying the fluorescent read-out in an automated fashion. Due to the high fecundity of Zebrafish, high throughput drug screening using Zebrafish larvae is feasible and could dramatically increase the chances of finding important new drugs.

The National Library of Medicine: PubMed One of the quickest and most comprehensive ways to find academic studies in both English and other languages is to use PubMed, maintained by the National Library of Medicine.6 The advantage of PubMed over previously mentioned sources is that it covers a greater number of domestic and foreign references. It is also free to use. If the publisher has a Web site that offers full text of its journals, PubMed will provide links to that site, as well as to sites offering other related data. User registration, a subscription fee, or some other type of fee may be required to access the full text of articles in some journals. 6
PubMed was developed by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM) at the National Institutes of Health (NIH). The PubMed database was developed in conjunction with publishers of biomedical literature as a search tool for accessing literature citations and linking to full-text journal articles at Web sites of participating publishers. Publishers that participate in PubMed supply NLM with their citations electronically prior to or at the time of publication.

Ask the doctor. I am a 64-year-old woman with high cholesterol caused by bad genes (familial hypercholesterolemia). Without medication, my cholesterol is above 450 mg/dL. So I am taking high-dose Lipitor (80 mg/day), WelChol, and Zetia to lower my cholesterol. I sometimes have pain and stiffness in my knees, and my shoulder, elbow, and wrist joints, plus the muscles in between, are stiff in the morning and hurt during the day. Two years ago I was diagnosed with bursitis in my hips. Could these problems be from the Lipitor? If so, is there another statin I could take that wouldn't do this? Author(s): Pasternak R.

CHAPTER 2. NUTRITION AND HYPERCHOLESTEROLEMIA Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and hypercholesterolemia.
Finding Nutrition Studies on Hypercholesterolemia The National Institutes of Health’s Office of Dietary Supplements (ODS) offers a searchable bibliographic database called the IBIDS (International Bibliographic Information on Dietary Supplements; National Institutes of Health, Building 31, Room 1B29, 31 Center Drive, MSC 2086, Bethesda, Maryland 20892-2086, Tel: 301-435-2920, Fax: 301-480-1845, E-mail:
[email protected]). The IBIDS contains over 460,000 scientific citations and summaries about dietary supplements and nutrition as well as references to published international, scientific literature on dietary supplements such as vitamins, minerals, and botanicals.7 The IBIDS includes references and citations to both human and animal research studies. As a service of the ODS, access to the IBIDS database is available free of charge at the following Web address: http://ods.od.nih.gov/databases/ibids.html. After entering the search area, you have three choices: (1) IBIDS Consumer Database, (2) Full IBIDS Database, or (3) Peer Reviewed Citations Only. Now that you have selected a database, click on the “Advanced” tab. An advanced search allows you to retrieve up to 100 fully explained references in a comprehensive format. Type “hypercholesterolemia” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.
7
Adapted from http://ods.od.nih.gov. IBIDS is produced by the Office of Dietary Supplements (ODS) at the National Institutes of Health to assist the public, healthcare providers, educators, and researchers in locating credible, scientific information on dietary supplements. IBIDS was developed and will be maintained through an interagency partnership with the Food and Nutrition Information Center of the National Agricultural Library, U.S. Department of Agriculture.

CHAPTER 4. PATENTS ON HYPERCHOLESTEROLEMIA Overview Patents can be physical innovations (e.g. chemicals, pharmaceuticals, medical equipment) or processes (e.g. treatments or diagnostic procedures). The United States Patent and Trademark Office defines a patent as a grant of a property right to the inventor, issued by the Patent and Trademark Office.8 Patents, therefore, are intellectual property. For the United States, the term of a new patent is 20 years from the date when the patent application was filed. If the inventor wishes to receive economic benefits, it is likely that the invention will become commercially available within 20 years of the initial filing. It is important to understand, therefore, that an inventor’s patent does not indicate that a product or service is or will be commercially available. The patent implies only that the inventor has “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States. While this relates to U.S. patents, similar rules govern foreign patents. In this chapter, we show you how to locate information on patents and their inventors. If you find a patent that is particularly interesting to you, contact the inventor or the assignee for further information. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical patents that use the generic term “hypercholesterolemia” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on hypercholesterolemia, we have not necessarily excluded non-medical patents in this bibliography.
Patents on Hypercholesterolemia By performing a patent search focusing on hypercholesterolemia, you can obtain information such as the title of the invention, the names of the inventor(s), the assignee(s) or the company that owns or controls the patent, a short abstract that summarizes the patent, and a few excerpts from the description of the patent. The abstract of a patent tends to be more technical in nature, while the description is often written for the public. Full patent descriptions contain much more information than is presented here (e.g. claims, references, figures, diagrams, etc.). We will tell you how to obtain this information later in the chapter. 8Adapted

Hypercholesterolemia
The following is an example of the type of information that you can expect to obtain from a patent search on hypercholesterolemia: •
Atorvastatin hemi-calcium form VII Inventor(s): Aronhime; Judith (Rehovot, IL), Lidor-Hadas; Ramy (Kafar-Saba, IL), Lifshitz; Revital (Herzlia, IL), Niddam; Valerie (Even-Yeouda, IL) Assignee(s): Teva Pharmaceutical Industries Ltd. (Petah Tiqva, IL) Patent Number: 6,605,636 Date filed: November 5, 2001 Abstract: The present invention provides a novel form of atorvastatin hemi-calcium designated Form VII and novel processes for its preparation whereby another crystalline form of atorvastatin hemi-calcium is suspended in ethanol, preferably absolute ethanol, and is converted to the new form, which is then isolated. The present invention further provides a method of reducing the plasma low density lipoprotein level in patients suffering from or susceptible to hypercholesterolemia and compositions and dosage forms for practicing the invention. Excerpt(s): The present invention relates to crystalline polymorphic forms of atorvastatin hemi-calcium and novel processes for preparing crystalline solids. Atorvastatin is a member of the class of drugs called statins. Statin drugs are currently the most therapeutically effective drugs available for reducing low density lipoprotein (LDL) particle concentration in the blood stream of patients at risk for cardiovascular disease. A high level of LDL in the bloodstream has been linked to the formation of coronary lesions which obstruct the flow of blood and can rupture and promote thrombosis. Goodman and Gilman, The Pharmacological Basis of Therapeutics 879 (9th ed. 1996). Reducing plasma LDL levels has been shown to reduce the risk of clinical events in patients with cardiovascular disease and patients who are free of cardiovascular disease but who have hypercholesterolemia. Scandinavian Simvastatin Survival Study Group, 1994; Lipid Research Clinics Program, 1984a, 1984b. The mechanism of action of statin drugs has been elucidated in some detail. They interfere with the synthesis of cholesterol and other sterols in the liver by competitively inhibiting the 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase enzyme ("HMG-CoA reductase"). HMG-CoA reductase catalyzes the conversion HMG to mevalonate, which is the rate determining step in the biosynthesis of cholesterol, and so, its inhibition leads to a reduction in the concentration of cholesterol in the liver. Very low density lipoprotein (VLDL) is the biological vehicle for transporting cholesterol and triglycerides from the liver to peripheral cells. VLDL is catabolized in the peripheral cells which releases fatty acids which may be stored in adopcytes or oxidized by muscle. The VLDL is converted to intermediate density lipoprotein (IDL), which is either removed by an LDL receptor, or is converted to LDL. Decreased production of cholesterol leads to an increase in the number of LDL receptors and corresponding reduction in the production of LDL particles by metabolism of IDL.

Combination therapy employing ileal bile acid transport inhibiting benzothipines and HMG Co-A reductase inhibitors Inventor(s): Glenn; Kevin C. (Maryland Heights, MO), Keller; Bradley T. (Chesterfield, MO), Manning; Robert E. (St. Louis, MO) Assignee(s): G.D. Searle & Co. (Chicago, IL) Patent Number: 6,642,268 Date filed: February 15, 2002 Abstract: Provided are novel benzothiepines, derivatives, and analogs thereof; pharmaceutical compositions containing them; and methods of using these compounds and compositions in medicine, particularly in the prophylaxis and treatment of hyperlipidemic conditions such as those associated with atherosclerosis or hypercholesterolemia, in mammals. Also provided are compositions and methods for combination therapy employing ileal bile acid transport inhibitors and HMG Co--A reductase inhibitors for the treatment of hyperlipidemic conditions. Excerpt(s): The present invention relates to novel benzothiepines, derivatives and analogs thereof, in combination with HMG Co--A reductase inhibitors, pharmaceutical compositions containing them, and use of these compositions in medicine, particularly in the prophylaxis and treatment of hyperlipidemic conditions such as is associated with atherosclerosis or hypercholesterolemia is mammals. It is well-settled that hyperlipidemic conditions associated with elevated concentrations of total cholesterol and low-density lipoprotein cholesterol are major risk factors for coronary heart disease and particularly atherosclerosis. Interfering with the circulation of bile acids within the lumen of the intestinal tract is found to reduce the levels of serum cholesterol is a causal relationship. Epidemiological data has accumulated which indicates such reduction leads to an improvement in the disease state of atherosclerosis. Stedronsky, in "Interaction of bile acids and cholesterol with nonsystemic agents having hypocholesterolemic properties," Biochimica et Biophysica Acta. 1210 (1994) 255-287 discusses the biochemistry, physiology and known active agents surrounding bile acids and cholesterol. Pathophysiologic alterations are shown to be consistent with interruption of the enterohepatic circulation of bile acids in humans by Heubi, J. E., et al. See "Primary Bile Acid Malabsorption: Defective in Vitro Ileal Active Bile Acid Transport", Gastroenterology, 1982:83:804-11. Web site: http://www.delphion.com/details?pn=US06642268__

Hydrazones and analogs as cholesterol lowering agents Inventor(s): Hasegawa; Hirohiko (Osaka, JP), Medina; Julio C. (San Carlos, CA) Assignee(s): Tularik Inc. (South San Francisco, CA) Patent Number: 6,605,615 Date filed: March 1, 2001 Abstract: Hydrazones and hydrazone analogs are provided which are useful as upregulators of LDL receptors and can be used in the treatment of hypercholesterolemia and related disorders and conditions. Excerpt(s): Atherosclerosis is disease resulting from excess cholesterol accumulation in the arterial walls, which forms plaques that inhibit blood flow and promote clot formation, ultimately causing heart attacks, stroke and claudication. The principal
138
Hypercholesterolemia
source of these cholesterol deposits are low-density lipoprotein (LDL) particles that are present in the blood. There is a direct correlation between LDL concentration and plaque formation in the arteries. LDL concentration is itself largely regulated by the supply of active LDL cell surface receptors which bind LDL particles and translocate them from the blood into the cell interior. Accordingly, the regulation of LDL receptor expression provides an important therapeutic target. Lipoprotein disorders have been previously called hyperlipoproteinemias and defined as elevation of a lipoprotein level above normal. Hyperlipoproteinemias result in elevations of cholesterol, triglycerides or both and are clinically important because of their contribution to atherosclerotic diseases and pancreatitis. Lipoproteins are spherical macromolecular complexes of lipid and protein. The lipid constituents of lipoproteins are esterified and unesterified (free) cholesterol, triglycerides, and phospholipids. Lipoproteins transport cholesterol and triglycerides from sites of absorption and synthesis to sites of utilization. Cholesteryl ester and triglycerides are nonpolar and constitute the hydrophobic core of lipoproteins in varying proportions. The lipoprotein surface coat contains the polar constituents-free cholesterol, phospholipids, and apolipoproteins--that permit these particles to be miscible in plasma.

Method for treating hypercholesterolemia, hyperlipidemia, and atherosclerosis Inventor(s): Cherukuri; Reddy Sastry V. (Folsom, CA), Cheruvanky; Rukmini (Folsom, CA), Lynch; Ike (El Dorado Hills, CA), McPeak; Patricia (El Dorado Hills, CA), Qureshi; Asaf A. (Madison, WI) Assignee(s): The RiceX Company (El Dorado Hills, CA) Patent Number: 6,558,714 Date filed: November 16, 2001 Abstract: A method for reducing mammalian serum total cholesterol, LDL cholesterol, apolipoprotein B and triglyceride levels, by ingesting a stabilized rice bran derivative selected from the group consisting of an enzyme treated stabilized rice bran, an insolubilized fraction and mixtures thereof, thereby reducing serum total cholesterol, LDL cholesterol, apolipoprotein B and triglyceride levels in said mammal. Excerpt(s): The present invention relates to methods for treating hypercholesterolemia, hyperlipidemia, and atherosclerosis in mammals by ingesting a stabilized rice bran derivative. Hypercholesterolemia is a condition with elevated levels of circulating total cholesterol, LDL-cholesterol and VLDL-cholesterol as per the guidelines of the Expert Panel Report of the National Cholesterol Educational Program (NCEP) of Detection, Evaluation of Treatment of high cholesterol in adults (see, Arch. Int. Med. (1988) 148, 3639). In particular, high level of LDL and VLDL are positively associated with coronary arteriosclerosis while the high levels of high density lipoproteins (HDL) are negative risk factors. The role of LDL oxidation is gaining much attention in the literature. It is well documented that LDL becomes oxidatively stressed under pathological conditions and is no longer recognized by the LDL receptors. The oxidized LDL is taken up by macrophages within the subendothelial space, leading to the formation of fatty streaks which are the basis of most advanced lesions. Hypercholesterolemia is implicated as a high risk factor of cardiovascular disease (CVD), including arteriosclerosis, atherosclerosis and xanthomatosis in humans. Hypercholesterolemia is influenced by diet, heredity, environment, life style, diseases and stress, leading to heart attacks and strokes at an early age.

(New York, NY) Patent Number: 6,699,832 Date filed: April 24, 2001 Abstract: The present invention relates to methods of treating obesity, diabetes, sexual dysfunction, atherosclerosis, insulin resistance, impaired glucose tolerance, hypercholesterolemia or hypertrigylceridemia using a neurotensin receptor ligand. The present invention also relates to pharmaceutical compositions and kits that comprise a neurotensin receptor ligand. Excerpt(s): The present invention relates to methods of treating obesity, diabetes, sexual dysfunction (including erectile dysfunction), atherosclerosis, insulin resistance, impaired glucose tolerance, hypercholesterolemia, or hypertrigylceridemia using a compound that is a neurotensin receptor ligand. The present invention also relates to compositions and kits that comprise a neurotensin receptor ligand. Obesity is a devastating disease. In addition to harming physical health, obesity can wreak havoc on mental health because obesity affects self-esteem, which ultimately can affect a person's ability to interact socially with others. Unfortunately, obesity is not well understood, and societal stereotypes and presumptions regarding obesity only tend to exacerbate the psychological effects of the disease. Because of the impact of obesity on individuals and society, much effort has been expended to find ways to treat obesity, but little success has been achieved in the long-term treatment and/or prevention of obesity. Neurotensin is a thirteen amino acid peptide that appears to have functions as a neurotransmitter and neuromodulator in the nervous system and as a local hormone in the periphery. Specifically, neurotensin is a neuromodulator of dopamine transmission and of anterior pituitary hormone secretion, and exerts potent hypothermic and analgesic effects in the brain. In the periphery, neurotensin is a paracrine and endocrine modulator of the digestive tract and acts as a growth factor on a variety of cells.

Quinolinyl and benzothiazolyl modulators Inventor(s): Furukawa; Noboru (Osaka, JP), Hagiwara; Atsushi (Osaka, JP), Houze; Jonathan B. (San Mateo, CA), McGee; Lawrence R. (Pacifica, CA), Rubenstein; Steven M. (Pacifica, CA), Shinkai; Hisashi (Osaka, JP) Assignee(s): Japan Tobacco, Inc. (Tokyo, JP), Tularik Inc. (So. San Francisco, CA) Patent Number: 6,583,157 Date filed: June 27, 2001 Abstract: Compounds, compositions and methods are provided that are useful in the treatment or prevention of a condition or disorder mediated by PAPAR.gamma. In particular, the compounds of the invention modulate the function of PAPAR.gamma. The subject methods are particularly useful in the treatment and/or prevention of diabetes, obesity, hypercholesterolemia, rheumatoid arthritis and atherosclerosis. Excerpt(s): The present invention relates to compounds that modulate the PAPAR.gamma. receptor and are useful in the diagnosis and treatment of type II diabetes (and complications thereof), hypercholesterolemia (and related disorders associated with abnormally high or low plasma lipoprotein or triglyceride levels) and inflammatory disorders. The peroxisome proliferator-activated receptors (PPARs) are transducer proteins belonging to the steroid/thyroid/retinoid receptor superfamily. The PPARs were originally identified as orphan receptors, without known ligands, but were named for their ability to mediate the pleiotropic effects of fatty acid peroxisome proliferators. These receptors function as ligand-regulated transcription factors that control the expression of target genes by binding to their responsive DNA sequence as heterodimers with RXR. The target genes encode enzymes involved in lipid metabolism and differentiation of adipocytes. Accordingly, the discovery of transcription factors involved in controlling lipid metabolism has provided insight into regulation of energy homeostasis in vertebrates, and further provided targets for the development of therapeutic agents for disorders such as obesity, diabetes and dyslipidemia. In an effort to understand the role of PAPAR.gamma. in adipocyte differentiation, several investigators have focused on the identification of PAPAR.gamma. activators. One class of compounds, the thiazolidinediones, which were known to have adipogenic effects on preadipocyte and mesenchymal stem cells in vitro, and antidiabetic effects in animal models of non-insulin-dependent diabetes mellitus (NIDDM) were also demonstrated to be PAPAR.gamma.-selective ligands. More recently, compounds that selectively activate murine PAPAR.gamma. were shown to possess in vivo antidiabetic activity in mice. Web site: http://www.delphion.com/details?pn=US06583157__

Hypercholesterolemia
Bioavailable fenofibrate compositions, methods for treating hyperlipidemia and hypercholesterolemia and processes for the preparation of such compositions Inventor(s): Femia, Robert A.; (Kinnelon, NJ), Fishkis, Oscar I.; (White Plains, NY), Patel, Damodar P.; (Elmwood Park, NJ), Ragunathan, Narayan; (West Nyack, NY) Correspondence: The Firm OF Karl F Ross; 5676 Riverdale Avenue; PO Box 900; Riverdale (bronx); NY; 10471-0900; US Patent Application Number: 20040142903 Date filed: January 16, 2003 Abstract: Pharmaceutical compositions for treating hyperlipidemia or hypercholesterolemia in mammals are described which comprise: 1 (a) fenofibrate 5 to 35 wt. -% (b) a cyclodextrin 4 to 30 wt. -% (c) an alkali metal or 0.1 to 10 wt. -%; and alkaline earth metal docusate and/or alkali metal or alkaline earth metal lauryl sulfate (d) a water-insoluble, wettable 5 to 30 wt. -% inorganic carrier capable of forming a dispersion of the fenofibrate and a pharmaceutically acceptable inert carrier or diluent.A therapeutically effective amount of the compositions are orally administered to mammals to treat hyperlipidemia or hypercholesterolemia. Excerpt(s): This invention relates to novel fenofibrate compositions with bioavailability. The invention further relates to compositions containing fenofibrate, a cyclodextrin, an alkaline metal or alkaline earth metal docusate and/or an alkali metal or alkaline earth metal lauryl sulfate, and a water-insoluble, wettable carrier which provide fenofibrate to patients in a highly bioavailable form without the need for co-micronization of fenofibrate with any of the other ingredients. Fenofibrate is a well known antihyperlipoproteinemic agent. See U.S. Pat. No. 4,058,552. Experience with oral administration of fenofibrate has shown that the bioavailability of the drug has not been as high as would be desirable. A good deal of research has been carried out over the years to obtain compositions containing fenofibrate that are orally administered to patients and which have improved bioavailability. According to U.S. Pat. No. 4,895,726 to CURTET et al compositions containing fenofibrate with improved bioavailability have been prepared in which the fenofibrate has been co-micronized in an intimate mixture with a solid surfactant such as sodium lauryl sulfate. CURTET et al expressly state that it is possible to improve the bioavailability to a significantly greater extent than that which would be achieved either by adding a surfactant, or by micronizing the fenofibrate on its own, or by intimately mixing the separately micronized fenofibrate and surfactant. Such a fenofibrate-containing composition is currently available on the market under the mark TRICOR.sup.R. Among the compositions actually exemplified in CURTET et al, all such compositions contain alpha-lactose monohydrate, a well known hydrosoluble carrier. The alpha-lactose monohydrate is added to the co-micronizate of fenofibrate and solid surfactant. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Combinations of cholesteryl ester transfer protein inhibitors and bile acid sequestering agents for cardiovascular indications Inventor(s): Glenn, Kevin C.; (Maryland Heights, MO), Sikorski, James A.; (Des Peres, MO) Correspondence: Banner & Witcoff; 1001 G Street N W; Suite 1100; Washington; DC; 20001; US Patent Application Number: 20040028644 Date filed: April 14, 2003 Abstract: The present invention provides combinations of cardiovascular therapeutic compounds for the prophylaxis or treatment of cardiovascular disease including hypercholesterolemia and atherosclerosis. Combinations disclosed include an cholesteryl ester transfer protein inhibitor combined with a bile acid sequestrant. Excerpt(s): This application claims priority of U.S. provisional application Ser. No. 60/142,682 filed Jul. 7, 1999 and of U.S. provisional application Ser. No. 60/113,955 filed Dec. 23, 1998. The present invention relates to methods of treating cardiovascular diseases, and specifically relates to combinations of compounds, compositions, and methods for their use in medicine, particularly in the prophylaxis and treatment of hyperlipidemic conditions such as are associated with atherosclerosis, hypercholesterolemia, and other coronary artery disease in mammals. More particularly, the invention relates to cholesteryl ester transfer protein (CETP) activity inhibiting compounds. The invention also relates to bile acid sequestering compounds. It is well-settled that hyperlipidemic conditions associated with elevated concentrations of total cholesterol and low-density lipoprotein (LDL) cholesterol are major risk factors for coronary heart disease and particularly atherosclerosis. Numerous studies have demonstrated that a low plasma concentration of high density lipoprotein (HDL) cholesterol is a powerful risk factor for the development of atherosclerosis (Barter and Rye, Atherosclerosis, 121, 1-12 (1996). HDL is one of the major classes of lipoproteins that function in the transport of lipids through the blood. The major lipids found associated with HDL include cholesterol, cholesteryl ester, triglycerides, phospholipids and fatty acids. The other classes of lipoproteins found in the blood are low density lipoprotein (LDL), intermediate density lipoprotein (IDL), and very low density lipoprotein (VLDL). Since low levels of HDL cholesterol increase the risk of atherosclerosis, methods for elevating plasma HDL cholesterol would be therapeutically beneficial for the treatment of atherosclerosis and other diseases associated with accumulation of lipid in the blood vessels. These diseases include, but are not limited to, coronary heart disease, peripheral vascular disease, and stroke. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Hypercholesterolemia
Compositions for reducing hypercholesterolemia and controlling of postprandial blood glucose and insulin levels Inventor(s): Christmas, Kevin Patrick; (Mason, OH), Elsen, Joseph James; (St. Bernard, OH), Helmers, Ralph Lawrence JR.; (Cincinnati, OH), Kester, Jeffrey John; (West Chester, OH), Prosise, Robert Lawrence; (Cincinnati, OH), Wehmejer, Thomas Joseph; (Cincinnati, OH) Correspondence: Michael Best & Friedrich, Llp; 100 E Wisconsin Avenue; Milwaukee; WI; 53202; US Patent Application Number: 20040086547 Date filed: October 21, 2003 Abstract: Beta-glucan soluble fiber and non-digestible fats are administered orally to reduce blood cholesterol levels and to control postprandial blood glucose and insulin levels. The beta-glucan soluble fiber and non-digestible fat may be administered as separate compounds, as a mixture, or combined with other materials and administered in the form of an appealing food. Excerpt(s): This application claims the benefit of U.S. Provisional Application Serial No. 60/196,410 filed on Apr. 12, 2000, in the name of Prosise et al. The present invention relates to methods and compositions for reducing blood cholesterol levels, and for controlling of postprandial blood glucose and insulin levels, by oral administration of beta-glucan soluble fiber and a non-digestible fat. High blood cholesterol (hypercholesterolemia) is recognized as a risk factor for coronary heart disease, which is a major health care problem. Epidemiological studies have demonstrated that, with few exceptions, populations consuming large quantities of saturated fat and cholesterol have a relatively high concentration of serum cholesterol and a high mortality rate from coronary heart disease. While it is recognized that other factors can also contribute to the development of cardiovascular disease, there appears to be a causal relationship between the concentration of serum cholesterol, in which hypercholesterolemia results in the accumulation of undesirable amounts of cholesterol in various parts of the circulatory system (arteriosclerosis) or in soft tissues (xanthomatosis), and coronary disease and coronary mortality rates. It is well accepted that lowering of blood cholesterol levels will reduce the risk of heart disease, as well as slow the progression of this chronic disease in individuals already suffering its effects. Typical therapy for persons with hypercholesterolemia includes strict control of dietary intake of fat, saturated fat, and cholesterol. In certain cases, this dietary regimen may be combined with a treatment of cholesterol lowering drugs, such as the bile acid sequestrants (e.g., colestipol and cholestyramine). Patient adherence to a stringent and prolonged dietary and drug regimen is often poor. The cholesterol lowering drugs can have unpleasant side effects and palatability is often extremely poor. Therefore, it would be particularly advantageous to have palatable food products that can replace or enhance the effectiveness of cholesterol lowering drugs.

By use of the controlled release pharmaceutical composition of the present invention, the blood level of pitavastatin can be maintained at an appropriate level immediately after administration over a long period of time. Thus, highly safety and effective treatment of hypercholesterolemia can be performed. Excerpt(s): The present invention relates to a controlled release pharmaceutical composition containing pitavastatin, which is an HMG-CoA reductase inhibitor, a salt thereof, or an ester thereof. Pitavastatin and salts and esters thereof are known to be useful as drugs for treating hypercholesterolemia, by virtue of their excellent HMGCoA reductase inhibitory activity (U.S. Pat. No. 5,856,336 and EP 0,304,063). Hypercholesterolemia treatment drugs such as the pitavastatin-containing drugs are used in the form of peroral preparations such as tablets, granules and capsules (U.S. Pat. No. 6,465,477 and WO 97/23200). In general, peroral drug preparations are designed such that the blood level of the active ingredient reaches its peak 0.5 to 3 hours after ingestion, and the level rapidly decreases afterward. However, since cholesterol is synthesized in the body during the period from midnight to morning, it is highly likely that blood level of the active ingredient does not match the time at which biosynthesis of cholesterol occurs. Although pitavastatin and salts and esters thereof are also known to exert high activity and have high safety, an excessively high blood level thereof is not preferred, from the viewpoint of prevention against the side effects.

Hypercholesterolemia
Abstract: The use of statins for the control of hypercholesterolemia is continually increasing. Although the side effects of statins are relatively uncommon, muscle myopathies may develop in response to statin therapy. The invention is the discovery of a correlation between statin related myopathy based on the presence of 3methylglutaconic acid (3MGA) in the urine. This correlation allows for the screening of both symptomatic and asymptomatic individuals for statin related myopathy. Excerpt(s): This application claims the benefit of priority of United States provisional application Serial No. 60/363,435 filed Mar. 12, 2002 which is incorporated herein by reference in its entirety. 3-Hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins) are the mainstay of therapy for hypercholesterolemia because of their effectiveness and exceptional safety profile. Nonetheless, many patients treated with statins have muscle symptoms, and some patients develop severe muscle toxicity. Little is known about the mechanism by which statin therapy leads to muscle toxicity. The recent withdrawal of cerivastatin from the U.S. market has highlighted both our ignorance and the need for postmarketing surveillance of these therapies (Farmer Lancet 358:1383-5; 2001). There are credible reports of patients who have muscle symptoms and normal serum creatine kinase levels while receiving statins. However, there is no way to determine if the source of the myopathy is the statin or a non-related cause. As statin therapy becomes used more aggressively in larger groups of patients, the importance of even minor toxic side effects of this therapy is magnified. Early detection of patients who may suffer toxic muscular reactions to these drugs would be extremely useful. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

Stable pharmaceutical formulation comprising a HMG-CoA reductase inhibitor Inventor(s): Kerc, Janez; (Ljubljana, SI) Correspondence: Bromberg & Sunstein Llp; 125 Summer Street; Boston; MA; 02110-1618; US Patent Application Number: 20040072894 Date filed: September 4, 2003 Abstract: Lovastatin, pravastatin, simvastatin, mevastatin, atorvastatin, and derivatives and analogs thereof are known as HMG-CoA reductase inhibitors and are used as antihypercholesterolemic agents. The majority of them are produced by fermentation using microorganisms of different species identified as species belonging to Aspergillus, Monascus, Nocardia, Amycolatopsis, Mucor or Penicillium genus, and some are obtained by treating the fermentation products using the methods of chemical synthesis or they are the products of total chemical synthesis.The aforementioned active substances may be destabilised by the environmental factors, their degradation may also be accelerated by interactions with other pharmaceutical ingredients, such as fillers, binders, lubricants, glidants and disintegrating agents, therefore the pharmaceutical ingredients and the process for preparation of the pharmaceutical formulation should be meticulously chosen to avoid the aforementioned undesired interactions and reactions.The present invention relates to a stable solid pharmaceutical formulation for the treatment of hypercholesterolemia and hyperlipidemia.

Lovastatin, pravastatin, simvastatin, mevastatin, atorvastatin, fluvastatin and cerivastatin, derivatives and analogs thereof are known as HMG-CoA reductase inhibitors and are used as antihypercholesterolemic agents. The majority of them are produced by fermentation using microorganisms of different species identified as species belonging to Aspergillus, Monascus, Nocardia, Amycolatopsis, Mucor or Penicillium genus. Some are obtained by treating the fermentation products using the methods of chemical synthesis like simvastatin or they are the products of total chemical synthesis like fluvastatin, atorvastatin and cerivastatin. The purity of the active substance is an important factor for manufacturing a safe and effective pharmaceutical formulation. Maximum possible purity of the product is of particular importance if the pharmaceutical product must be taken on a longer term basis in the treatment or prevention of high cholesterol levels in blood. Accumulation of impurities from drugs of a lower level of purity may cause a variety of side effects during treatment. Besides impurities, that cannot be completely eliminated

in the process of preparation of the active substance, degradation products occurring by subjecting the final pharmaceutical formulation to various environmental factors such as temperature, moisture, low pH and light, may also impose a problem. HMG-CoA reductase inhibitors occurring in the form of salts in the final pharmaceutical formulation, such as atorvastatin, pravastatin, fluvastatin and cerivastatin, are particularly sensitive to an acidic environment in which hydroxy acids are degraded into a lactone.

Inventor(s): Hutchinson, Howard Gerard; (Delaware, DE), Raza, Ali; (Cheshire, GB) Correspondence: Morgan Lewis & Bockius Llp; 1111 Pennsylvania Avenue NW; Washington; DC; 20004; US Patent Application Number: 20040072852 Date filed: November 6, 2003 Abstract: The invention provides a method for the treatment of heterozygous familial hypercholesterolemia by administering the compound (E)-7-[4-(4-fluorphenyl)-6isopropyl-2-[methyl(methylsulfonyl)amino]pyrim- idin-5-yl](3R,5S)-3,5-dihydroxy-hept6-enoic acid or a pharmaceutically acceptable salt thereof. Excerpt(s): The present invention relates to a new use of a statin drug in the treatment of severe heterozygous familial hypercholesterolemia (HeFH)and in particular patients with baseline LDL-C>220 mg/dL. There is now a large body of evidence obtained from clinical trials demonstrating that pharmacological agents (particularly the statins) that reduce low density lipoprotein-cholesterol LDL-C levels also decrease Chronic Heart Disease (CHD) risk (Lipid Research Clinics Program 1984, Gould et al 1998). Taken together, the trials published to date support the concept that lowering LDL-C levels should be the principal goal of lipid altering therapy (Ansell et al 1999), and that the reduction in coronary risk that occurs during treatment with statins is directly related to these agents' LDL-C lowering effects (Gould et al 1998, Pedersen et al 1998). Primary hyperlipidemia is a term used to describe a defect in lipoprotein metabolism. The lipoproteins commonly affected are LDL-C, which transports mainly cholesterol, and VLDL-C, which transports mainly TG. Most subjects with hyperlipidemia have a defect in LDL metabolism, characterised by raised cholesterol, LDL-C, levels, with or without raised triglyceride levels; such subjects are termed hypercholesterolemic (Fredrickson Type IL). Familial hypercholesterolemia (FH) is caused by any one of a number of genetically determined defects in the LDL receptor, which is important for the entry of cholesterol into cells. The condition is characterised by a reduced number of functional LDL receptors, and is therefore associated with raised serum LDL-C levels due to an increase in LDL. In its heterozygous form (HeFH) it is one of the commonest genetic diseases, with a frequency of about 1 in 500 in the United Kingdom (US), the United States (US), and Japan (Myant 1981, Mabuchi et al 1979).

Some, such as ginkgo, valerian, and saw palmetto, seem genuinely useful, while others, such as ephedra, tansy, and nightshade, can actually be dangerous. As the use of unfamiliar botanicals spreads, the need to steer patients toward the few truly useful preparations and warn them away from ineffective, dangerous alternatives is becoming an increasingly significant priority. This volume, from the publishers of Physicians Desk Reference, brings together the findings of the German Regulatory Authority's herbal

[email protected]. Website: www.mcgraw-hill.co.uk. PRICE: $79.95; plus shipping and handling. ISBN: 0077095251. Summary: Focal segmental glomerulosclerosis (FSGS) is not a disease but a pathologic lesion, a scarring of a portion of the glomerulus (a group of capillaries that are part of the filtering units of the kidney). This chapter on focal segmental glomerulosclerosis(FSGS) is from a book on nephrology (the study of the kidney and kidney diseases) designed for general practitioners and family care providers that offers strategies for the management of patients with renal (kidney) damage. Among glomerular disorders that affect children and young adults, FSGS is the most common disorder leading to end stage renal disease (ESRD). The lesion is more frequent and the severity of the disease is greater in patients of African-American origin. Clinically, the lesions of FSGS can be observed in a wide variety of disorders. In the idiopathic (of unknown cause) variety, there is proteinuria (protein in the urine), hypoalbuminemia (low levels of protein in the blood), and generalized edema (fluid accumulation), together with varying degrees of hypertriglyceridemia and hypercholesterolemia (high levels of fats in the blood). Since FSGS is a histologic diagnosis, a renal biopsy is necessary. The pathogenesis of this disease continues to be elusive; however, in recent years studies point to the role of transforming growth factor beta (TGF-b) in inducing the sclerosis. Most cases of FSGS tend to be resistant to steroid therapy as well as to therapy with alkylating agents such as cyclophosphamide. Controlled trials have documented the efficacy of cyclosporine in inducing a remission of the proteinuria, particularly in children; however, relapses tend to occur upon withdrawal of cyclosporine. In severe edema, intravenous furosemide often is necessary. Antihypertensive (high blood pressure medications) therapy should consist of ACE inhibitors and calcium channel blockers. 2 tables. 15 references.

Summary: Primary biliary cirrhosis (PBC) is an autoimmune liver disease that generally affects middle-aged women and that is characterized by ongoing inflammatory destruction of the bile ducts. This destruction leads to chronic cholestasis (lack of bile flow) and biliary cirrhosis, with consequent complications such as portal hypertension and liver failure. This chapter on PBC is from a comprehensive and authoritative textbook that covers disorders of the gastrointestinal tract, biliary tree, pancreas, and liver, as well as the related topics of nutrition and peritoneal disorders. Topics include epidemiology; pathogenesis; clinical features (symptoms); diagnosis; natural history; medical treatment; complications of chronic cholestasis and their management, including bone disease, fat-soluble vitamin deficiency, hypercholesterolemia, hyperlipidemia, pruritus (itching), and steatorrhea; liver transplantation; and autoimmune cholangitis or antimitochondrial antibody-negative PBC.

Summary: Somatic gene therapy refers to the introduction of genetic material into a specific organ or tissue in order to treat an inherited or acquired disease. This chapter, from a medical textbook on diabetes, presents an overview of the current status of somatic gene therapy for metabolic disease. The authors focus on liver-directed gene transfer for the purpose of illustration and uses homozygous familial hypercholesterolemia as a model. A final section of the chapter covers some of the issues related to somatic gene therapy for Type 1 diabetes mellitus (insulin-dependent or IDDM). The authors note that most of the issues relating to the successful development of gene therapy for diabetes mellitus are technical issues similar to those encountered in other diseases: targeting of the transgene to the appropriate tissue and achieving stable, regulated expression of the transgene. Another important issue for diabetes mellitus is the choice of gene for gene transfer. For most patients with IDDM, the insulin gene would appear to be the appropriate therapeutic gene for transfer. Another approach would be to transduce immunomodulatory cytokines into the pancreatic islets to prevent the autoimmune destruction that causes Type 1 diabetes. 1 figure. 2 tables. 66 references.

Contact: This publication may be available from your local medical library. Call for information. ISBN: 0070275009. Summary: The authors of this chapter suggest that, to a considerable extent, future progress in geriatric medicine is likely to be coupled to progress in basic and medical genetics. Specific attention is given to two specific areas: (1) basic considerations of genetics and aging; and (2) genetic syndromes that modulate aspects of the senescent phenotype. The former considers such aspects as maximum life span as a constitutional feature of speciation, the association between heredity and longevity, estimation of the number of genetic loci involved in human aging, sex differences in longevity, and genetic mechanisms and aging. The latter covers progeroid syndromes, Werner's syndrome, the Hutchinson-Gilford syndrome, ataxia telangiectasia (an autosomal, recessively-inherited disorder), Down's syndrome, other segmental progeroid syndromes, familial hypercholesterolemia, hereditary amyloidosis, familial Alzheimer's disease, Huntington's disease, and antigeroid syndromes. Consideration also is given to the potential association between parental age and mutation, including point mutations, and maternal age and aneuploidy. 150 references.

The author summarizes the most characteristic patterns of serum lipids in patients with renal disease and renal failure. Guidelines for the detection, evaluation, and treatment of hypercholesterolemia in adults have been established in the U.S. and Europe. These guidelines recommend that total cholesterol levels be used for screening purposes. All persons in the so-called high category (cholesterol greater than 240 mg per dL) require measurements of low-density lipoprotein (LDL) cholesterol levels; the measurements are used as a guide to the selection of treatment. The chapter concludes with recommended treatment and patient care management strategies. 4 figures. 3 tables. 153 references. (AA-M). •

in the United States. Four major types of diabetes have been defined: insulin dependent diabetes mellitus (Type 1 Diabetes), noninsulin dependent diabetes mellitus (Type 2 Diabetes), gestational diabetes mellitus (GDM), and diabetes secondary to other conditions. Impaired glucose tolerance (IGT) is a class that encompasses persons whose glucose tolerance is intermediate between normal and diabetes ranges. Screening is most appropriately carried out in groups at high risk for NIDDM. Major risk factors for NIDDM include older age, obesity, family history of diabetes, race or ethnicity of black, Hispanic or American Indian, and the presence of complications related to diabetes. The author outlines the scientific basis for the diagnostic criteria, the circumstances and methods for the diagnosis of diabetes in the United States, the use of the oral glucose tolerance test, the frequency and methods of screening for diabetes in the United States, the principles of screening for undiagnosed NIDDM, controversies in screening for NIDDM, and screening in high risk populations. The author concludes that the choice of screening method and criteria to be used depends on the screening situation. In public screening programs, considerations of cost and efficiency are important and it might be considered important to screen only very high risk groups to ensure high yields of positive screenees, although this would miss significant numbers of persons with NIDDM. In physicians' offices, where the focus is on care of the individual patient, it would appear appropriate to relax the screening exclusions and be more inclusive. Screening for undiagnosed NIDDM can also be accomplished in the context of programs directed toward other medical conditions that are frequent in people with diabetes, such as hypertension and hypercholesterolemia. 15 figures. 13 tables. 87 references. •

CHAPTER 7. RESEARCHING MEDICATIONS Overview While a number of hard copy or CD-ROM resources are available for researching medications, a more flexible method is to use Internet-based databases. Broadly speaking, there are two sources of information on approved medications: public sources and private sources. We will emphasize free-to-use public sources.
U.S. Pharmacopeia Because of historical investments by various organizations and the emergence of the Internet, it has become rather simple to learn about the medications recommended for hypercholesterolemia. One such source is the United States Pharmacopeia. In 1820, eleven physicians met in Washington, D.C. to establish the first compendium of standard drugs for the United States. They called this compendium the U.S. Pharmacopeia (USP). Today, the USP is a non-profit organization consisting of 800 volunteer scientists, eleven elected officials, and 400 representatives of state associations and colleges of medicine and pharmacy. The USP is located in Rockville, Maryland, and its home page is located at http://www.usp.org/. The USP currently provides standards for over 3,700 medications. The resulting USP DI Advice for the Patient can be accessed through the National Library of Medicine of the National Institutes of Health. The database is partially derived from lists of federally approved medications in the Food and Drug Administration’s (FDA) Drug Approvals database, located at http://www.fda.gov/cder/da/da.htm. While the FDA database is rather large and difficult to navigate, the Phamacopeia is both user-friendly and free to use. It covers more than 9,000 prescription and over-the-counter medications. To access this database, simply type the following hyperlink into your Web browser: http://www.nlm.nih.gov/medlineplus/druginformation.html. To view examples of a given medication (brand names, category, description, preparation, proper use, precautions, side effects, etc.), simply follow the hyperlinks indicated within the United States Pharmacopeia (USP). Below, we have compiled a list of medications associated with hypercholesterolemia. If you would like more information on a particular medication, the provided hyperlinks will direct you to ample documentation (e.g. typical dosage, side effects, drug-interaction risks, etc.).

Commercial Databases In addition to the medications listed in the USP above, a number of commercial sites are available by subscription to physicians and their institutions. Or, you may be able to access these sources from your local medical library.
Mosby’s Drug Consult Mosby’s Drug Consult database (also available on CD-ROM and book format) covers 45,000 drug products including generics and international brands. It provides prescribing information, drug interactions, and patient information. Subscription information is available at the following hyperlink: http://www.mosbysdrugconsult.com/. PDRhealth The PDRhealth database is a free-to-use, drug information search engine that has been written for the public in layman’s terms. It contains FDA-approved drug information
168
Hypercholesterolemia
adapted from the Physicians’ Desk Reference (PDR) database. PDRhealth can be searched by brand name, generic name, or indication. It features multiple drug interactions reports. Search PDRhealth at http://www.pdrhealth.com/drug_info/index.html. Other Web Sites Drugs.com (www.drugs.com) reproduces the information in the Pharmacopeia as well as commercial information. You may also want to consider the Web site of the Medical Letter, Inc. (http://www.medletter.com/) which allows users to download articles on various drugs and therapeutics for a nominal fee.
Researching Orphan Drugs Although the list of orphan drugs is revised on a daily basis, you can quickly research orphan drugs that might be applicable to hypercholesterolemia by using the database managed by the National Organization for Rare Disorders, Inc. (NORD), at http://www.rarediseases.org/. Scroll down the page, and on the left toolbar, click on “Orphan Drug Designation Database.” On this page (http://www.rarediseases.org/search/noddsearch.html), type “hypercholesterolemia” (or synonyms) into the search box, and click “Submit Query.” When you receive your results, note that not all of the drugs may be relevant, as some may have been withdrawn from orphan status. Write down or print out the name of each drug and the relevant contact information. From there, visit the Pharmacopeia Web site and type the name of each orphan drug into the search box at http://www.nlm.nih.gov/medlineplus/druginformation.html. You may need to contact the sponsor or NORD for further information. NORD conducts “early access programs for investigational new drugs (IND) under the Food and Drug Administration’s (FDA’s) approval ‘Treatment INDs’ programs which allow for a limited number of individuals to receive investigational drugs before FDA marketing approval.” If the orphan product about which you are seeking information is approved for marketing, information on side effects can be found on the product’s label. If the product is not approved, you may need to contact the sponsor. The following is a list of orphan drugs currently listed in the NORD Orphan Drug Designation Database for hypercholesterolemia: •
Sodium dichloroacetate http://www.rarediseases.org/nord/search/nodd_full?code=56
If you have any questions about a medical treatment, the FDA may have an office near you. Look for their number in the blue pages of the phone book. You can also contact the FDA through its toll-free number, 1-888-INFO-FDA (1-888-463-6332), or on the World Wide Web at www.fda.gov.

Coffee Break: Tutorials for Biologists18 Coffee Break is a general healthcare site that takes a scientific view of the news and covers recent breakthroughs in biology that may one day assist physicians in developing treatments. Here you will find a collection of short reports on recent biological discoveries. Each report incorporates interactive tutorials that demonstrate how bioinformatics tools are used as a part of the research process. Currently, all Coffee Breaks are written by NCBI staff.19 Each report is about 400 words and is usually based on a discovery reported in one or more articles from recently published, peer-reviewed literature.20 This site has new articles every few weeks, so it can be considered an online magazine of sorts. It is intended for general background information. You can access the Coffee Break Web site at the following hyperlink: http://www.ncbi.nlm.nih.gov/Coffeebreak/.
Other Commercial Databases In addition to resources maintained by official agencies, other databases exist that are commercial ventures addressing medical professionals. Here are some examples that may interest you: •
CliniWeb International: Index and table of contents to selected clinical information on the Internet; see http://www.ohsu.edu/cliniweb/.
•
Medical World Search: Searches full text from thousands of selected medical sites on the Internet; see http://www.mwsearch.com/.
18 Adapted 19
from http://www.ncbi.nlm.nih.gov/Coffeebreak/Archive/FAQ.html.
The figure that accompanies each article is frequently supplied by an expert external to NCBI, in which case the source of the figure is cited. The result is an interactive tutorial that tells a biological story. 20 After a brief introduction that sets the work described into a broader context, the report focuses on how a molecular understanding can provide explanations of observed biology and lead to therapies for diseases. Each vignette is accompanied by a figure and hypertext links that lead to a series of pages that interactively show how NCBI tools and resources are used in the research process.
177
APPENDIX B. PATIENT RESOURCES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines written with the patient in mind. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. Since new guidelines on hypercholesterolemia can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internet-based services that post them.
Patient Guideline Sources The remainder of this chapter directs you to sources which either publish or can help you find additional guidelines on topics related to hypercholesterolemia. Due to space limitations, these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in cases where the contact information is provided, contacting the publisher or author directly. The National Institutes of Health The NIH gateway to patients is located at http://health.nih.gov/. From this site, you can search across various sources and institutes, a number of which are summarized below. Topic Pages: MEDLINEplus The National Library of Medicine has created a vast and patient-oriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages” which list links to available materials relevant to hypercholesterolemia. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas. Recently, MEDLINEplus listed the following when searched for “hypercholesterolemia”:
178
Hypercholesterolemia
Genetic Disorders http://www.nlm.nih.gov/medlineplus/geneticdisorders.html Heart Attack http://www.nlm.nih.gov/medlineplus/heartattack.html Liver Transplantation http://www.nlm.nih.gov/medlineplus/livertransplantation.html Metabolic Disorders http://www.nlm.nih.gov/medlineplus/metabolicdisorders.html Stroke http://www.nlm.nih.gov/medlineplus/stroke.html Weight Loss and Dieting http://www.nlm.nih.gov/medlineplus/weightlossanddieting.html You may also choose to use the search utility provided by MEDLINEplus at the following Web address: http://www.nlm.nih.gov/medlineplus/. Simply type a keyword into the search box and click “Search.” This utility is similar to the NIH search utility, with the exception that it only includes materials that are linked within the MEDLINEplus system (mostly patient-oriented information). It also has the disadvantage of generating unstructured results. We recommend, therefore, that you use this method only if you have a very targeted search. The Combined Health Information Database (CHID) CHID Online is a reference tool that maintains a database directory of thousands of journal articles and patient education guidelines on hypercholesterolemia. CHID offers summaries that describe the guidelines available, including contact information and pricing. CHID’s general Web site is http://chid.nih.gov/. To search this database, go to http://chid.nih.gov/detail/detail.html. In particular, you can use the advanced search options to look up pamphlets, reports, brochures, and information kits. The following was recently posted in this archive: •

Preventing Progression of Renal Disease: News Briefings for Science Writers on Transplantation, Dialysis and Kidney Research (memorandum) Source: New York, NY: National Kidney Foundation, Inc. March 26-27, 1990. 7 p. Contact: Available from National Kidney Foundation, Inc. 30 East 33rd Street, New York, NY 10016. (800) 622-9010 or (212) 889-2210. Summary: This technical paper prepared for the National Kidney Foundation's 1990 science writers news briefing on transplantation, dialysis, and kidney/urology research discusses the mechanisms underlying the progression of renal disease. Accumulating evidence indicates that the risk factors underlying the progression of chronic renal disease include hypertension, hypercholesterolemia, invasion of the kidney by inflammatory cells, proteinuria and/or persistence of the initial pathogenic insult responsible for renal damage. The theorized participation of each risk factor is discussed. The author concludes that the risk factors may be interrelated and may potentiate each other at different stages of the evolution and progression of renal disease. The NIH Search Utility
The NIH search utility allows you to search for documents on over 100 selected Web sites that comprise the NIH-WEB-SPACE. Each of these servers is “crawled” and indexed on an ongoing basis. Your search will produce a list of various documents, all of which will relate in some way to hypercholesterolemia. The drawbacks of this approach are that the information is not organized by theme and that the references are often a mix of information for professionals and patients. Nevertheless, a large number of the listed Web sites provide useful background information. We can only recommend this route, therefore, for relatively rare or specific disorders, or when using highly targeted searches. To use the NIH search utility, visit the following Web page: http://search.nih.gov/index.html. NORD (The National Organization of Rare Disorders, Inc.) NORD provides an invaluable service to the public by publishing short yet comprehensive guidelines on over 1,000 diseases. NORD primarily focuses on rare diseases that might not be covered by the previously listed sources. NORD’s Web address is http://www.rarediseases.org/. A complete guide on hypercholesterolemia can be purchased from NORD for a nominal fee. Additional Web Sources A number of Web sites are available to the public that often link to government sites. These can also point you in the direction of essential information. The following is a representative sample: •

Finding Associations There are several Internet directories that provide lists of medical associations with information on or resources relating to hypercholesterolemia. By consulting all of associations listed in this chapter, you will have nearly exhausted all sources for patient associations concerned with hypercholesterolemia. The National Health Information Center (NHIC) The National Health Information Center (NHIC) offers a free referral service to help people find organizations that provide information about hypercholesterolemia. For more information, see the NHIC’s Web site at http://www.health.gov/NHIC/ or contact an information specialist by calling 1-800-336-4797. Directory of Health Organizations The Directory of Health Organizations, provided by the National Library of Medicine Specialized Information Services, is a comprehensive source of information on associations. The Directory of Health Organizations database can be accessed via the Internet at http://www.sis.nlm.nih.gov/Dir/DirMain.html. It is composed of two parts: DIRLINE and Health Hotlines. The DIRLINE database comprises some 10,000 records of organizations, research centers, and government institutes and associations that primarily focus on health and biomedicine. To access DIRLINE directly, go to the following Web site: http://dirline.nlm.nih.gov/. Simply type in “hypercholesterolemia” (or a synonym), and you will receive information on all relevant organizations listed in the database. Health Hotlines directs you to toll-free numbers to over 300 organizations. You can access this database directly at http://www.sis.nlm.nih.gov/hotlines/. On this page, you are given the option to search by keyword or by browsing the subject list. When you have received your search results, click on the name of the organization for its description and contact information. The Combined Health Information Database Another comprehensive source of information on healthcare associations is the Combined Health Information Database. Using the “Detailed Search” option, you will need to limit your search to “Organizations” and “hypercholesterolemia”. Type the following hyperlink into your Web browser: http://chid.nih.gov/detail/detail.html. To find associations, use the drop boxes at the bottom of the search page where “You may refine your search by.” For publication date, select “All Years.” Then, select your preferred language and the format

APPENDIX C. FINDING MEDICAL LIBRARIES Overview In this Appendix, we show you how to quickly find a medical library in your area.
Preparation Your local public library and medical libraries have interlibrary loan programs with the National Library of Medicine (NLM), one of the largest medical collections in the world. According to the NLM, most of the literature in the general and historical collections of the National Library of Medicine is available on interlibrary loan to any library. If you would like to access NLM medical literature, then visit a library in your area that can request the publications for you.21
Finding a Local Medical Library The quickest method to locate medical libraries is to use the Internet-based directory published by the National Network of Libraries of Medicine (NN/LM). This network includes 4626 members and affiliates that provide many services to librarians, health professionals, and the public. To find a library in your area, simply visit http://nnlm.gov/members/adv.html or call 1-800-338-7657.
Medical Libraries in the U.S. and Canada In addition to the NN/LM, the National Library of Medicine (NLM) lists a number of libraries with reference facilities that are open to the public. The following is the NLM’s list and includes hyperlinks to each library’s Web site. These Web pages can provide information on hours of operation and other restrictions. The list below is a small sample of

Fragments resulting from proteolytic cleavage of complement proteins are designated with lower-case letter suffixes, e.g., C3a. Inactivated fragments may be designated with the suffix 'i', e.g. C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol e.g. C1 or C4b,2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1, IgG3; C1q binds to a single IgM molecule or two adjacent IgG molecules. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides, and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3; activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P. Both result in the cleavage of C5 and the formation of the membrane attack complex. Complement activation also results in the formation of many biologically active complement fragments that act as anaphylatoxins, opsonins, or chemotactic factors.
