BACKGROUND Plasma cholesteryl ester transfer protein (CETP) functions to transfer cholesteryl ester from HDL to triglyceride-rich lipoproteins and regulates plasma HDL cholesterol level. A common mutation, the exon 15 A to G substitution at codon 442 (D442G) results in reduced plasma CETP activity and increased plasma HDL cholesterol level. Meanwhile, hormone replacement therapy (HRT) in postme...

The present study examines the interactive effects of three fatty acids: myristic, palmitic and stearic acids, with dietary cholesterol, on lipoprotein metabolism in the hamster. Each saturated fatty acid was fed at a concentration of 100 g pure synthetic triacylglycerol/kg in the presence of 100 g triolein/kg and was fed in the presence of 0.05, 1.2 or 2.4 g dietary cholesterol/kg. Dietary cho...

BACKGROUND: Cholesterol ester transfer protein (CETP) plays a major role in regulating the levels of LDL- and HDL-cholesterol. We previously observed a fish-oil-induced elevation of low-density lipoprotein (LDL)-and very-low-density lipoprotein (VLDL)-cholesterol concentrations and a decrease in high-density lipoprotein (HDL)-cholesterol concentration in F1B hamsters. The molecular mechanism/s ...

Recombination of low and very low density lipoproteins (VLDL and LDL) from normal subjects with plasma from patients with non-insulin-dependent diabetes mellitus significantly increased the reduced rate of transfer of cholesteryl ester to these lipoproteins, which is characteristic of diabetic plasma, whereas diabetic VLDL and LDL reduced cholesteryl ester transfer rates in normal plasma. VLDL ...

Cholesteryl ester transfer activity is increased in plasma of cholesterol-fed rabbits. To investigate the mechanisms leading to changes in activity, we measured cholesteryl ester transfer protein (CETP) mass by RIA and CETP mRNA abundance by Northern and slot blot analysis using a human CETP cDNA probe in control (n = 8) and cholesterol-fed rabbits (n = 10). Cholesterol feeding (chow plus 0.5% ...

During infection and inflammation there is a cascade of reactions that occurs in the host collectively known as the acute-phase response (APR).1 Besides alterations in acute-phase reactants (plasma proteins), the APR is also associated with changes in lipoproteins.2 Increasing evidence suggests that high density lipoproteins (HDL) are a critical part of the acute phase response (APR) of the inn...
