Cholesteryl ester transfer between high density lipoprotein and phospholipid bilayers.
High density lipoprotein-associated cholesteryl esters (HDL CE) are taken up by many cells without parallel uptake of HDL apoproteins, a pathway we have termed "selective uptake." The first step in this pathway, the reversible incorporation of HDL CE into the plasma membrane, is the subject of the present study. To examine the role of membrane proteins, the rate of HDL CE incorporation into iso...
متن کاملTransfer of cholesteryl ester into high density lipoprotein by cholesteryl ester transfer protein: effect of HDL lipid and apoprotein content.
Recombinant high density lipoprotein (rHDL) particles were prepared by cosonication of purified lipids and human apoproteins and incubated with partly purified cholesteryl ester transfer protein (CETP) and low density lipoprotein (LDL) containing [3H]cholesteryl ester. Increasing the triglyceride content relative to cholesteryl ester in rHDL significantly decreased the ability of the particles ...
متن کاملCholesteryl ester transfer from phospholipid vesicles to human density lipoproteins.
The exchange of cholesteryl esters between different lipoproteins was reported to bae mediated by a protein present in human plasma. In this study wer have examined the movement of cholesteryl ester from unilamellar phospholipid vesicles to high density lipoprotein (HDL). Experimental conditions were establisehd so that vesicles containing egg yolk lecithin and cholesteryl oleatea (molar ratio ...
متن کاملRelationship between lipoprotein lipase and high density lipoprotein cholesterol in mice: modulation by cholesteryl ester transfer protein and dietary status.
Plasma lipoprotein lipase (LPL) activity correlates with high density lipoprotein (HDL) cholesterol levels in humans. However, in several mouse models created either through transgenesis or targeted inactivation of LPL, no significant changes in HDL cholesterol values have been evident. One possible explanation for this species difference could be the absence of plasma cholesteryl ester transfe...
متن کاملMolecular cloning, sequence, and expression of cynomolgus monkey cholesteryl ester transfer protein. Inverse correlation between hepatic cholesteryl ester transfer protein mRNA levels and plasma high density lipoprotein levels.
A cDNA clone containing the coding region for cynomolgus monkey cholesteryl ester transfer protein (CETP) was isolated by the polymerase chain reaction with primers based on the human CETP cDNA sequence and cDNA synthesized from liver poly (A+) RNA. Analysis of that cDNA indicated that the nucleotide and amino acid sequences of cynomolgus monkey CETP were greater than 95% homologous with the hu...
