Previous research shows generally greater proportional elevation in apolipoprotein B (apoB) levels than in low-density lipoprotein cholesterol (LDL-C) in coronary heart disease (CHD) case subjects compared with control subjects. The Atherosclerosis Risk in Communities study provided general populations of 7261 men and women free of cardiovascular symptoms for evaluating the associations between...

Epidemiological studies have shown that low plasma levels of High Density Lipoprotein Cholesterol (HDL-C) are associated with an increased risk for myocardial infarction. These studies suggested that by increasing HDL-C levels one could reduce cardiovascular risk. However, emerging evidence from studies in animals and humans indicate that high levels of HDL-C are not sufficient to confer athero...

We previously reported that hyperhomocysteinemia (HHcy), an independent risk factor of coronary artery disease (CAD), is associated with increased atherosclerosis and decreased plasma high-density lipoprotein cholesterol (HDL-C) in cystathionine beta-synthase-/apolipoprotein E-deficient (CBS(-/-)/apoE(-/-)) mice. We observed that plasma homocysteine (Hcy) concentrations are negatively correlate...

Diets that reduce atherosclerosis risk lower levels of HDL cholesterol (HDL-C), but the significance of this is unclear. To better understand the mechanism of this phenomenon we studied the turnover of HDL apolipoproteins A-I and A-II in 13 subjects on two contrasting metabolic diets. Upon changing from high to low intake of saturated fat and cholesterol the mean HDL-C decreased 29% from 56 +/-...

HDL (high-density lipoproteins) remove cell cholesterol and protect from atherosclerosis. The major HDL protein is apoA-I (apolipoprotein A-I). Most plasma apoA-I circulates in lipoproteins, yet ~5% forms monomeric lipid-poor/free species. This metabolically active species is a primary cholesterol acceptor and is central to HDL biogenesis. Structural properties of lipid-poor apoA-I are unclear ...

OBJECTIVE Increasing HDL levels is a potential strategy for the treatment of atherosclerosis. METHODS AND RESULTS ITX5061, a molecule initially characterized as a p38 MAPK inhibitor, increased HDL-C levels by 20% in a human population of hypertriglyceridemic subjects with low HDL levels. ITX5061 also moderately increased apoA-I but did not affect VLDL/LDL cholesterol or plasma triglyceride co...

Individuals with mixed dyslipidemia, including high triglycerides (TGs) and low high density lipoprotein cholesterol (HDL-C), have increased risk for coronary events. We examined the effect of rare genetic variants in the APOA5 gene region on plasma HDL-C, apolipoprotein A-I (apoA-I), and TG response to fenofibric acid monotherapy and in combination with statins. The APOA5 gene region was seque...

We examined the mechanisms responsible for the decrease in HDL cholesterol (HDL-C) levels after the consumption of a diet low in total fat, saturated fat, and cholesterol. Twenty-one subjects with a mean age of 58+/-12 years were placed on a baseline isocaloric diet (15% protein, 49% carbohydrate, 36% fat, and 150 mg/1000 kcals of cholesterol) and then switched to an NCEP Step 2 diet (15% prote...
