apoE-deficient mice have been created by homologous recombination in ES cells. On a low fat, low cholesterol chow diet these animals have plasma cholesterol levels of 494 mg/dl compared with 60 mg/dl in control animals, and when challenged with a high fat Western-type diet, these animals have plasma cholesterol levels of 1821 mg/dl compared with 132 mg/dl(More)
We present GERMLINE, a robust algorithm for identifying segmental sharing indicative of recent common ancestry between pairs of individuals. Unlike methods with comparable objectives, GERMLINE scales linearly with the number of samples, enabling analysis of whole-genome data in large cohorts. Our approach is based on a dictionary of haplotypes that is used(More)
The human apo-E gene has been isolated from a lambda phage library using as a probe the previously reported apo-E cDNA clone pE-301. Lambda apo-E was mapped and subcloned, and the apo-E gene was completely sequenced. The DNA sequence was compared with that of a near full length cDNA clone pE-368 and revealed three introns. The first intron was in the region(More)
Focal recruitment of monocytes and lymphocytes is one of the earliest detectable cellular responses in the formation of lesions of atherosclerosis. This localized accumulation of leukocytes is a multistep process in which the endothelium remains intact and may regulate leukocyte recruitment by expressing specific adhesion molecules. To examine the(More)
The association of low-density lipoprotein (LDL) subclass patterns with coronary heart disease was investigated in a case-control study of nonfatal myocardial infarction. Subclasses of LDL were analyzed by gradient gel electrophoresis of plasma samples from 109 cases and 121 controls. The LDL subclass pattern characterized by a preponderance of small, dense(More)
BACKGROUND Cardiac conduction, as assessed by electrocardiographic PR interval and QRS duration, is an important electrophysiological trait and a determinant of arrhythmia risk. OBJECTIVE We sought to identify common genetic determinants of these measures. METHODS We examined 1604 individuals from the island of Kosrae, Federated States of Micronesia, an(More)
OBJECTIVE A semisynthetic diet with varying amounts of cholesterol was used to achieve hypercholesterolemia and atherosclerosis in LDL receptor-deficient (LDLR-/-) mice. Atherosclerotic lesions were measured as cross-sectional area at the aortic root and brachiocephalic artery and by en face analysis of aortic lesion area in 209 male and female animals on(More)
A possible relationship between change in dietary cholesterol absorption and plasma lipoprotein responsiveness was examined in 18 normal subjects fed low fat low cholesterol, high fat low cholesterol, and high fat high cholesterol diets. For the group, neither dietary cholesterol nor dietary fat affected the percentage dietary cholesterol absorption,(More)
Initial description of apolipoprotein (apo) E-deficient transgenic mice demonstrated the development of severe hypercholesterolemia due to probable delayed clearance of large atherogenic particles from the circulation. Examination of these mice demonstrated foam cell accumulation in the aortic root and pulmonary arteries by 10 weeks of age. In the present(More)
In a recent communication, we showed that human very low density lipoprotein (VLDL) apolipoprotein E (Apo E) from different individuals appears upon two-dimensional gel electrophoretic analysis in either one of two complex patterns. These have been designated class alpha and class beta. Mixing of VLDL from different subjects revealed that not all alpha or(More)
