Application

Cholesterol 5β,6β-epoxide was used to treat PC12 cells or HepG2 and Caco-2 cells to study the effects of cholesterol oxidation.

Biochem/physiol Actions

Cholesterol 5β,6β-epoxide is an oxysterol produced as an oxidation product of cholesterol. Oxysterols are cytotoxic and induce death in monocytes, smooth muscle cells and endothelial cells. The mechanism of apoptosis induced by oxysterols may involve caspases or DNA fragmentation.

The adaptive response induced by the lipid peroxidation products, such as phosphatidylcholine hydroperoxide, lysophosphatidylcholine (LysoPC), 15-deoxy-Delta(12,14)-prostaglandin J(2), 4-hydroxynonenal (4-HNE), hydroxyoctadecadienoic acid, 7-hydroxycholesterol, and cholesterol 5beta,6beta-epoxide, was investigated in this study. Although these products have been implicated in oxidative stress-related diseases

The cytotoxicity of the oxysterols 25-hydroxycholesterol, 7beta-hydroxycholesterol, cholesterol-5alpha,6alphaepoxide, cholesterol-5beta,6beta-epoxide, 19-hydroxycholesterol and 7-ketocholesterol was examined in U937 cells, a human monocytic blood cell line. 7beta-Hydroxycholesterol, cholesterol-5beta,6beta-epoxide, and 7-ketocholesterol, at 30 micromol/L concentration, were found to be cytotoxic to this cell line

In the nineteen sixties it was proposed that cholesterol might be involved in the etiology of cancers and cholesterol oxidation products were suspected of being causative agents. Researchers had focused their attention on cholesterol-5,6-epoxides (5,6-ECs) based on several lines of
