Early steps in steroidogenesis: intracellular cholesterol trafficking
Steroid hormones are made from cholesterol, primarily derived from lipoproteins that enter cells via receptor-mediated endocytosis. In endo-lysosomes, cholesterol is released from cholesterol esters by lysosomal acid lipase (LAL; disordered in Wolman ...

Cholesterol esters of long-chain saturated fatty acids (C12 to C22), as well as those of the C18 unsaturated fatty acids (oleic, linoleic, and linolenic), were prepared by the ester interchange method, starting with cholesteryl acetate and the methyl ...

A randomized double-blind study was made in 67 modestly hypercholesterolemic subjects by replacing 50 g of daily dietary fat by the same amount of a rapeseed oil preparation without and with fat-soluble sitostanol esters.

The influence of exogenous cholesterol on hepatic lipid composition of the rat*
Rats were fed diets containing cottonseed oil and/or cholesterol, cholic acid, methyl esters of long-chain fatty acids, and tocopherol. Livers, hearts, and aortas were examined histologically; liver lipids were fractionated by silicic acid chromatography;

In vitro incorporation of cholesterol-14C in to very low density lipoprotein cholesteryl esters
The cholesteryl esters of very low density lipoproteins become labeled when human plasma is incubated with cholesterol-14C. The relative order of magnitude of the specific activity of the cholesteryl esters of the major lipoprotein fractions is: high ...

Recent studies from our laboratory (Yancey, P.G., and R. W. St. Clair. 1992. Arterioscler. Thromb. 12: 1291-1304) have shown that cultured peritoneal macrophages from White Carneau (WC) pigeons clear cholesteryl esters at a slower rate than do ...

The formation and consequences of cholesterol-rich deposits in atherosclerotic lesions
Cardiovascular diseases remain the leading cause of death throughout the world. Accumulation of lipoprotein-associated lipids and their interaction with macrophages are early steps in the development of atherosclerotic lesions.

Purification of neutral lipid fractions by thin-layer chromatography on aluminum oxide
Two-stage thin-layer chromatography on Aluminum Oxide G has been used to separate triglycerides, cholesterol, cholesterol esters, and diglycerides from contaminating fatty acids present in the lipid mixtures.
