Rat luteal cells utilize high-density lipoproteins (HDL) as a source of cholesterol for steroid synthesis. Both the free and esterified cholesterol of HDL are utilized by these cells. In this report, we have examined the relative uptake of free and esterified cholesterol of HDL by cultured rat luteal cells. Incubation of the cells with HDL labeled with [3H]cholesterol or [3H]cholesteryl linolea...

Serum/plasma sample pairs, collected both during (12-h) fasting and nonfasting from 44 healthy subjects, were analyzed for total cholesterol, high-density lipoprotein (HDL) cholesterol, and triglycerides. Values for total cholesterol and triglycerides averaged 2.1% and 5.2%, respectively, higher for serum than for plasma. Values for HDL cholesterol were not different. Triglyceride concentration...

Diets rich in polyunsaturated fatty acids lower plasma HDL cholesterol concentrations when compared to diets rich in saturated fatty acids. We investigated the mechanistic basis for this effect in the hamster and sought to determine whether reduced plasma HDL cholesterol concentrations resulting from a high polyunsaturated fat diet are associated with a decrease in reverse cholesterol transport...

Monascus purpureus is known to produce pigment molecules. The pigments were extracted from M. fermented rice. In-vitro antioxidant effects of observed and presumed alleviate oxidative stress related atherosclerosis effect in rats fed with high fat diet (HFD) for 14 weeks. formation lipid peroxide due the oxidation serum was higher HFD. While, feeding rice (groups III-V) significantly lowered (2...

High density lipoprotein (HDL) receptor activity was decreased by the addition of platelet-derived growth factor (PDGF) to cholesterol-loaded cultured human skin fibroblasts. Effects were observed within 12 hours, coinciding with increases in tritiated thymidine incorporation into DNA. The PDGF-mediated decrease in HDL binding was associated with a decrease in cholesterol efflux promoted by HDL...

High density lipoprotein (HDL) with and without apolipoprotein (apo) E was quantified and characterized in subjects with three genotypes of cholesteryl ester transfer protein (CETP) deficiency: the nonsense mutation in intron 14 (10 homozygotes and 5 heterozygotes); the missense mutation in the exon 15 (3 homozygotes and 9 heterozygotes); and the Int14A/D442G in 6 compound heterozygotes. ApoE-p...

Clinical and epidemiologic studies have consistently shown that low levels of high-density lipoprotein (HDL) cholesterol are strongly associated with an increase in the risk of coronary artery disease.1 Moreover, hypercholesterolemic mice with genetic defects in HDL metabolism are markedly atherosclerotic,2,3 providing compelling evidence that HDL is a key modulator of the disease in animal mod...

BACKGROUND AND PURPOSE High-density lipoprotein (HDL) cholesterol is an established protective factor for ischemic stroke. However, the contribution of HDL subclasses to stroke risk and its subtypes is uncertain. METHODS A prospective nested case-control study of 40- to 85-year-old Japanese was undertaken using frozen serum samples collected from 5280 men and 7524 women. They participated in ...

Low HDL-cholesterol is common among patients with cardiovascular disease. Well-designed epidemiological studies carried out over the previous three decades have defined the prognostic significance of low HDL-cholesterol. Indeed, a recent evaluation of patients undergoing coronary angiography showed that factors related to HDL-cholesterol, but not to LDL-cholesterol, were primarily responsible f...

BACKGROUND Dyslipidemia is a major health problem in China and an important modifiable cardiovascular disease (CVD) risk factor. This study aimed to describe the prevalence of dyslipidemia and low high density lipoprotein cholesterol (HDL-cholesterol) and associated risk factors among adults in rural northwest China. METHODS In a cross-sectional analyses involving 2,980 adults aged >18 years,...
