BACKGROUND LDL cholesterol has a causal role in the development of cardiovascular disease. Improved understanding of the biological mechanisms that underlie the metabolism and regulation of LDL cholesterol might help to identify novel therapeutic targets. We therefore did a genome-wide association study of LDL-cholesterol concentrations. METHODS We used genome-wide association data from up to...
KV-2920 is a novel acyl-CoA: cholesterol acyltransferase (ACAT) inhibitor. To confirm the efficacy of KV-2920-low density lipoprotein (LDL) complex (KV-LDL complex) as a drug-carrier complex on experimental atherosclerosis, we examined its inhibitory effects in vitro and in vivo. LDL was isolated from human plasma and the KV-LDL complex was prepared by incubation in the presence of Celite 545. ...
Subcellular localization of nonesterified cholesterol has been determined in normal human fibroblasts from cultures incubated with human low density lipoprotein (LDL). Nonesterified and esterified cholesterol content of fibroblasts, grown initially in the absence of cholesterol, increased significantly after a 1-hour incubation with LDL. Digitonin was used to localize nonesterified cholesterol ...
Studies were carried out to determine the independent and interactive effects of dietary fat and cholesterol on the regulation of hepatic apoB/E receptor expression and its relationship to hepatic cholesterol concentrations and low density lipoprotein (LDL) particle characteristics. Guinea pigs were fed 15% (w/w) fat diets (lard, olive oil, or corn oil) with cholesterol levels corresponding to ...
OBJECTIVE The hypothesis that cholesterol that enters the cell within low-density lipoprotein (LDL) particles rapidly equilibrates with the regulatory pool of intracellular cholesterol and maintains cholesterol homeostasis by reducing cholesterol and LDL receptor synthesis was validated in the fibroblast but not in the hepatocyte. Accordingly, the present studies were designed to compare the ef...
OBJECTIVE We assessed the association between different blood lipid measures and risk of fatal/nonfatal coronary heart disease (CHD). RESEARCH DESIGN AND METHODS We conducted an observational study of patients with type 2 diabetes from the Swedish National Diabetes Register. Baseline LDL cholesterol, non-HDL cholesterol, ratio of non-HDL to HDL cholesterol (non-HDL:HDL), and ratio of triacylg...
Most patients with coronary artery disease do not have elevated plasma or low density lipoprotein (LDL) cholesterol. To test whether the protein moiety of LDL, LDL B, might be a parameter to identify ischemic heart disease, the plasma cholesterol, triglyceride, LDL cholesterol, and LDL B were measured in 100 consecutive patients undergoing cardiac catheterization. On the basis of coronary angio...
p38 MAPK has been strongly implicated in the development of atherosclerosis, but its role in cholesterol ester accumulation in macrophages and formation of foam cells, an early step in the development of atherosclerosis, has not been investigated. We addressed this issue and made some brand new observations. First, elevated intracellular cholesterol level induced by the exposure to LDL-activate...
The hydromethylglutaryl coenzyme A (HMG CoA) reductase inhibitors, “statins,” have been remarkably effective in reducing low-density lipoprotein (LDL) cholesterol concentration, decreasing the incidence of coronary heart disease (CHD) and stroke, and extending survival (1–5). Statins inhibit the synthesis of cholesterol primarily in the liver. The hepatocyte, as its content of cholesterol decre...
