Acetylated low density lipoprotein (Ac-LDL) is taken up by bovine aortic and adrenal capillary cells but not by brain capillary cells. This indicates that the uptake of Ac-LDL is not a feature of all types of endothelial cell. A quantitative examination of lipoprotein uptake by flow cytometry showed cells in G2M took up 45% more Ac-LDL than those in G1S. Compared with confluent cultures, sub-co...

OBJECTIVE To determine mechanisms contributing to the altered lipoprotein profile associated with aging and menopause, apolipoprotein B-100 (apoB-100) and apoA-I kinetic behavior was assessed. METHODS AND RESULTS Eight premenopausal (25+/-3 years) and 16 postmenopausal (65+/-6 years) women consumed for 6 weeks a standardized Western diet, at the end of which a primed-constant infusion of deut...

accumulating evidence suggest that in patients with diabetes mellitus, increased rate of lipoprotein oxidation and oxidative stress have important role in diabetic angiopathy, including nephropathy. to evaluate the association of oxidized low- density lipoprotein (ox-ldl) with the development of diabetic nephropathy, plasma level of ox-ldl were measured in 70 diabetic patients with macro and 63...

Ultracentrifugally isolated high density lipoprotein (HDL) particles of d greater than 1.125 g/ml promote net transport of cholesterol from cultured cells. Consequently, when cultured human fibroblasts and arterial smooth muscle cells were incubated with HDL3 (d = 1.125-1.21 g/ml) and "very high" density lipoprotein (VHDL, d = 1.21-1.25 g/ml), low density lipoprotein (LDL) receptor activity was...

OBJECTIVE We aimed to clarify the influence of apolipoprotein C-III (apoCIII) on human apolipoprotein B metabolism. METHODS AND RESULTS We studied the kinetics of 4 very-low-density lipoprotein (VLDL), intermediate-density lipoprotein (IDL), and low-density lipoprotein (LDL) types containing: (1) otherApos-CIII-: none of apoCIII, apoAII, apoCI, apoCII, or apoE; (2) otherApos+CIII-: no apoCIII...

BACKGROUND Elevated low density lipoprotein (LDL) and lipoprotein(a) are independent risk factors for the development of atherosclerosis. Using a proteomic approach we aimed to determine early changes in arterial protein expression in transgenic mice containing both human LDL and lipoprotein(a) in circulation. METHODS AND RESULTS Plasma lipid analyses showed the lipoprotein(a) transgenic mice...

A systematic review and meta-analysis of Mendelian randomization studies using Medline, Cumulative Index to Nursing Allied Health Literature Complete, Scopus databases. Sixteen involving 34,050 patients with an abdominal aortic aneurysm (AAA) 2,205,894 controls were included. Meta-analyses suggested that a 1 standard deviation increase in high-density lipoprotein cholesterol (HDL-C) significant...

Areduction in low-density lipoprotein (LDL) cholesterol lowers coronary heart disease (CHD) by 24% to 31% in subjects with prevalent CHD; this reduction occurs with the use of several statins, including simvastatin1 and pravastatin.2,3 Additional reductions in CHD could come from further reductions in LDL cholesterol, as was suggested by the Post Coronary Artery Bypass Graft clinical trial (POS...

Dyslipidemia is a major risk factor for coronary heart disease (CHD), and current guidelines support low-density lipoprotein cholesterol (LDL-C) as a primary target of therapy.[1] Previous studies suggest that increasing high-density lipoprotein cholesterol (HDL-C) and reducing triglycerides and small LDL particles may also have a positive impact in prevention.[2] These factors are considered s...

CETP (cholesteryl ester-transfer protein) is essential for neutral lipid transfer between HDL (high-density lipoprotein) and LDL (low-density lipoprotein) and plays a critical role in the reverse cholesterol transfer pathway. In clinical trials, CETP inhibitors increase HDL levels and reduce LDL levels, and therefore may be used as a potential treatment for atherosclerosis. In this review, we c...
