Cholesteryl ester transfer protein (CETP) has a well-defined role in plasma neutral lipid transport. CETP synthesized by human adipose tissue may contribute to the plasma CETP pool. CETP mRNA abundance increases in subcutaneous adipose tissue in response to cholesterol feeding and we have hypothesized that CETP gene expression is regulated by a specific pool of cellular sterol. In the present s...
AIM Cholesteryl ester transfer protein (CETP) is an important lipid transfer factor in plasma that enhances prothrombinase activity in purified systems. This study was conducted to test the association of plasma CETP activity with venous thrombosis (VTE) and to address the procoagulant mechanism of CETP activity in prothrombinase assays. METHODS We measured CETP lipid transfer activity in pla...
Human atherosclerotic intima contains mast cells that secrete the neutral protease chymase into the intimal fluid, which also contains HDL-modifying proteins, such as cholesteryl ester transfer protein (CETP), in addition to abundant amounts of nascent discoidal HDL particles. Here, we studied chymase-dependent degradation of a) CETP isolated from human plasma and b) CETP-HDL complexes as well ...
In vitro lipoprotein lipase enhances the cholesteryl ester transfer protein (CETP)-mediated transfer of cholesteryl esters from high density lipoproteins (HDL) to very low density lipoproteins as a result of lipolysis-induced alterations in lipoprotein lipids that lead to increased binding of CETP. To determine if there are similar changes during alimentary lipemia, we measured the transfer of ...
Plasma cholesteryl ester transfer protein (CETP) concentrations were measured in Japanese subjects by an ELISA with two different monoclonal antibodies that were raised against rabbit CETP and cross-reacted against human CETP. Among 63 patients who consecutively underwent coronary angiography, the plasma CETP of 37 patients with luminal stenosis > or = 50% in their coronary arteries was not sig...
The plasma cholesteryl ester transfer protein (CETP) plays a major role in the catabolism of HDL cholesteryl ester (CE). CETP transgenic mice have decreased HDL cholesterol levels and have been reported to have either increased or decreased early atherosclerotic lesions. To evaluate the impact of CETP expression on more advanced forms of atherosclerosis, we have cross-bred the human CETP transg...
OBJECTIVE Cholesteryl ester transfer protein (CETP) is a target gene for the liver X receptor (LXR). The aim of this study was to further explore this regulation in the monocyte-macrophage lineage and its modulation by lipid loading and inflammation, which are key steps in the process of atherogenesis. METHODS AND RESULTS Exposure of bone marrow-derived macrophages from human CETP transgenic ...
The anti-dyslipidemic drug niacin has recently been shown to reduce the hepatic expression and plasma levels of CETP. Since liver macrophages contribute to hepatic CETP expression, we investigated the role of macrophages in the CETP-lowering effect of niacin in mice. In vitro studies showed that niacin does not directly attenuate CETP expression in macrophages. Treatment of normolipidemic human...
The plasma cholesteryl ester-transfer protein (CETP, Mr 74,000) promotes exchange of both neutral lipids and phospholipids (phosphatidylcholine, PC) between lipoproteins. To investigate the mechanism of facilitated lipid transfer, CETP was incubated with unilamellar egg PC vesicles containing small amounts of cholesteryl ester (CE) or triglyceride, and then analyzed by gel filtration chromatogr...
