The substrate specificity of lipid transfer protein has been examined in whole plasma in vitro by following the redistribution of high density lipoprotein (HDL)-derived [3H]cholesteryl ester (CE) into apolipoprotein (apo) B-containing lipoproteins using density gradient ultracentrifugation. HDL-derived [3H]CEs were incubated with plasma or isolated lipoprotein classes (very low density lipoprot...

The scavenger receptor class B, type I (SR-BI) mediates the cellular selective uptake of cholesteryl esters and other lipids from high-density lipoproteins (HDL) and low-density lipoproteins (LDL). This process, unlike classical receptor-mediated endocytosis, does not result in lipoprotein degradation. Instead, the lipid depleted particles are released into the medium. Here we show that selecti...

OBJECTIVE To compare the magnitude of lipid, and lipoproteins, especially the lipoprotein(a) [Lp(a)], in controls and patients with coronary heart disease (CHD). METHODS Serum total cholesterol, triglyceride, HDL-C, LDL-C, VLDL-C, apo A1, apo B, and Lp(a) levels were determined in 37 patients with CHD and 25 age matched control subjects. RESULTS A significant difference (P < 0.001) in lipid...

In dairy cows the peripartum period involves endocrine and metabolic changes to compensate for the increased energy requirement aggravated by reduced feed intake. Cows adjust to the resulting negative energy balance with the mobilization of lipids from adipose tissue that, if excessive, could lead to many transition disorders compromising the offspring’s growth and well-being. The aim of this s...

Although low-density lipoprotein (LDL) is widely recognized as the major atherogenic lipoprotein and the primary target of lipid-lowering therapy,1 other lipoprotein species nonetheless appear to be involved in atherogenesis. These include very low-density lipoproteins (VLDL), intermediate-density lipoproteins (IDL), and highdensity lipoproteins (HDL). Both VLDL and IDL are triglyceride-rich li...

Electrophoresis of serum on filter paper followed by staining 3 of the lipoprotein fractions with lipid dyes is technically the simplest method for the separation and estimation of serum lipoproteins. A number of procedures for the staining of separated lipoproteins on paper with various lipid dyes have appeared (1-8), but the only comprehensive consideration of the quantitative aspects of dye ...

Stimulated peripheral blood mononuclear cells (PBMC) can oxidize normal lipoproteins, and sufficiently oxidized lipoproteins are cytotoxic. However, the role of lipid peroxidation in the inhibition of mitogen-stimulated PBMC proliferation by physiologic concentrations of normal lipoproteins is unclear. In the present investigation, normal low density lipoprotein (LDL) and very low density lipop...

Plasma apoC-III levels correlate with triglyceride (TG) levels and are a strong predictor of CVD outcomes. ApoC-III elevates TG in part by inhibiting LPL. ApoC-III likely inhibits LPL by competing for lipid binding. To probe this, we used oil-drop tensiometry to characterize binding of six apoC-III variants to lipid/water interfaces. This technique monitors the dependence of lipid binding on su...

BACKGROUND Patients with coronary artery disease (CAD) are known to have several lipoprotein abnormalities. We examined plasma cholesterol concentrations of major lipoproteins and their subclasses, using a gel permeation HPLC, to establish an association between a lipoprotein subclass pattern and the presence of CAD. METHODS We performed a simple and fully automated HPLC, followed by mathemat...
