Tracking cell cholesterol with cholesterol oxidase.
Journal of Lipid Research, 1992 Sterols are ubiquitous and essential constituents of all eukaryotic cells, found either esterified and stored in droplet form (l), or unesterified and integrated into bilayers (2) . Sterols not only play a major structural role in membranes, but serve as precursors for steroid hormones and bile acids (3). The distribution of cholesterol within the cell

Cholesterol oxides inhibit cholesterol esterification by lecithin: cholesterol acyl transferase [PDF]
Brazilian Journal of Pharmaceutical Sciences, 2009 Cholesterol oxides are atherogenic and can affect the activity of diverse important enzymes for the lipidic metabolism. The effect of 7β-hydroxycholesterol, 7-ketocholesterol, 25-hydroxycholesterol, cholestan-3β,5α,6β-triol,5,6β ...

Cholesterol and Cholesterol Esters in Mycoplasma [PDF]
Journal of General Microbiology, 1965 Free and esterified cholesterol were determined in the lipid extract of nine parasitic and saprophytic Mycoplasma strains. The saprophytic strains were usally free from esterified cholesterol. Esterified cholesterol was found in the parasitic strains at a ratio of 1:8 to 1:3 to free cholesterol; in the growth medium the ratio was about 4:1 [4-14C ...

27-Hydroxylation of oncosterone by CYP27A1 switches its activity from pro-tumor to anti-tumor
Journal of Lipid Research, 2023 Oncosterone (6-oxo-cholestane-3β,5α-diol; OCDO) is an oncometabolite and a tumor promoter on estrogen receptor alpha-positive breast cancer (ER(+) BC) and triple-negative breast cancers (TN BC). OCDO is an oxysterol formed in three steps from cholesterol:

Association between cholesterol-phospholipid vesicles and cholesterol crystals in human gallbladder bile [PDF]
, 1989 Rapid aggregation of cholesterol-phospholipid vesicles in gallbladder bile seems to be the first event in the production of cholesterol crystals, a prerequisite for cholesterol gallstone formation.

Cholesterol Efflux and Reverse Cholesterol Transport [PDF]
, 2014 Both alterations of lipid/lipoprotein metabolism and inflammatory events contribute to the formation of the atherosclerotic plaque, characterized by the accumulation of abnormal amounts of cholesterol and macrophages in the artery wall. Reverse cholesterol transport (RCT) may counteract the pathogenic events leading to the formation and development of ...

Inhibition of pancreatic cholesterol esterase reduces cholesterol absorption in the hamster [PDF]
, 2004 BACKGROUND: Pancreatic cholesterol esterase has three proposed functions in the intestine: 1) to control the bioavailability of cholesterol from dietary cholesterol esters; 2) to contribute to incorporation of cholesterol into mixed micelles; and 3) to ...
