Cholesteryl ester transfer protein (CETP) is a key protein involved in the reverse cholesterol transport pathway. The regulation of CETP by dietary fats is not clearly understood. Transgenic mice expressing human CETP under the control of its natural flanking region were fed low- or high-fat diets enriched in monounsaturated fatty acids (MUFAs) or saturated fatty acids in the presence or absenc...

Cholesteryl ester transfer protein (CETP) promotes the transfer of cholesteryl esters from antiatherogenic HDLs to proatherogenic apolipoprotein B (apoB)-containing lipoproteins, including VLDLs, VLDL remnants, IDLs, and LDLs. A deficiency of CETP is associated with increased HDL levels and decreased LDL levels, a profile that is typically antiatherogenic. Studies in rabbits, a species with nat...

BACKGROUND The role of cholesteryl ester transfer protein (CETP) in the development of atherosclerosis is still open to debate. In the Investigation of Lipid Level Management to Understand its Impact in Atherosclerotic Events (ILLUMINATE) trial, inhibition of CETP in patients with high cardiovascular risk was associated with increased high-density lipoprotein levels but increased risk of cardio...

ApoCI (apolipoprotein CI) is a potent inhibitor of plasma CETP [CE (cholesteryl ester) transfer protein]. The relevance of apoCI overexpression as a method for CETP blockade in vivo was addressed in the present study in CETPTg/apoCITg mice (mice expressing both human CETP and apoCI). Despite a significant reduction in specific CETP activity in CETPTg/apoCITg mice compared with CETPTg mice [tran...

In order to investigate the direct effect of cholesteryl ester transfer protein (CETP) on the structure and composition of HDL in vivo, simian CETP was expressed in Fisher rat that spontaneously displays high plasma levels of HDL1. In the new CETPTg rat line, the production of active CETP by the liver induced a significant 48% decrease in plasma HDL cholesterol, resulting in a 34% decrease in t...

Cholesteryl ester transfer protein (CETP) mediates an important pathway for reverse cholesterol transport. Concentrations of CETP in fasting plasma were measured by radioimmunoassay in two different groups of hyperlipoproteinemic subjects. Plasma CETP concentrations measured by radioimmunoassay correlated closely with cholesterol ester transfer activity in normal plasma (r = 0.86). In the first...

Source and Description of Primers. The conserved sequences of human and rabbit cholesteryl ester transfer protein gene (CETP) (GenBank accession numbers NM000078 and M27486, respectively) were used to design primers to PCR amplify porcine CETP. The primers amplified a 970-bp fragment of porcine CETP gene spanning an intron between exon 1 and exon 2. The porcine CETP sequence (GenBank accession ...

Cholesteryl ester transfer protein (CETP) catalyzes the net transfer of cholesteryl ester (CE) between lipoproteins in exchange for triglyceride (heteroexchange). It is generally held that CETP primarily associates with HDL and preferentially transfers lipids from this lipoprotein fraction. This is illustrated in normal plasma where HDL is the primary donor of the CE transferred to VLDL by CETP...

Plasma cholesteryl ester transfer protein (CETP) mediates the transfer of cholesteryl esters (CE) between lipoproteins and was reported to also directly mediate the uptake of high density lipoprotein (HDL) CE by human Hep G2 cells and fibroblasts. The present study investigates that uptake and its relationship to a pathway for "selective uptake" of HDL CE that does not require CETP. HDL3 labele...

Pharmacological approaches to reduce obesity have not resulted in dramatic reductions in the risk of coronary heart disease (CHD). Exercise, in contrast, reduces CHD risk even in the setting of obesity. Cholesteryl Ester Transfer Protein (CETP) is a lipid transfer protein that shuttles lipids between serum lipoproteins and tissues. There are sexual-dimorphisms in the effects of CETP in humans. ...
