Research Interests
Atherosclerosis, the primary cause of heart disease and stroke, has an important genetic component, but the genes contributing to the common forms of the disease are largely unknown. Studies in humans have been hampered by the etiologic complexity of atherosclerosis. One approach to the problem involves studies in mouse models, which are more amenable to genetic dissection of complex traits. The genes and pathways identified in mice can them be tested in human populations.

Familial combined hyperlipidemia (FCH), characterized by elevated levels of triglyceride and cholesterol, is a common cause of early heart disease. Studies of a mouse model of FCH (Castellani et al. Nature Genetics, 1998) implicates the thioredoxin system, the primary regulator of cellular redox states, in the control of lipid metabolism in liver and muscle. The hyperlipidemia mouse has a defect in a gene, designated Hyplip1, that encodes a thioredoxin-binding protein. A locus contributing to FCH on human chromosome 1q contains the ortholog of the Hyplip1 gene, and we are investigating whether variations of the gene may contribute to the human disorder.

As yet, human studies have not succeeded in identifying genetic factors in atherosclerosis that act by affecting vascular cell functions, a major problem being the difficulty of accurately evaluating the severity of disease by noninvasive techniques. Using genetic studies in mice, we have identified at least two pathways in atherosclerosis that affect cellular functions. Genetic variations affecting these pathways in mice can completely block the development of lesions, even on the background of extreme hyperlipidemia resulting from mutations of apolipoprotein E or the low density lipoprotein receptor. One of the pathways influences endothelial cell responses to oxidized lipoproteins, while the other appears to control interactions with blood cells. Neither pathway has significant effects on cholesterol metabolism, blood pressure or other common risk factors. We are searching for the underlying genes using a combination biochemical, genetic and genomics approaches.

Jake Lusis received his Ph.D. in Biophysics from Oregon State University. He was a postdoctoral fellow with Kenneth Paigen in the Molecular Biology Department, Roswell Park Memorial Institute, Buffalo, NY. Since 1979, he has been on the faculty at the University of California, Los Angeles, where he is presently Professor in the Departments of Microbiology and Medicine. He has a secondary appointment in the Department of Human Genetics, where he is also Vice Chairman. He has served on advisory panels for the National Institutes of Health, the American Heart Association, and various private companies and organizations. Presently, he serves on the Board of Scientific Counselors, NHLBI. Among his awards are the Bristol-Myers Squibb Award for Distinguished Achievement in Research, the American Heart Association Duff Award, and the NAVBO Benditt Award.
