Application

Cholesterol 5β,6β-epoxide was used to treat PC12 cells or HepG2 and Caco-2 cells[1] to study the effects of cholesterol oxidation.[2]

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 mutagenicity of oxysterols, cholesterol-3beta,5alpha,6beta-triol (alpha-Triol), 7-keto-cholesterol (7-Keto) and cholesterol-5alpha,6alpha-epoxide (alpha-Epox) were examined by the Ames method and chromosome aberration test in this study. Only alpha-Triol concentration-dependently caused an increase of bacterial revertants in the absence of metabolic activating enzymes

Oxysterols are oxygenated derivatives of cholesterol that may be formed endogenously or absorbed from the diet. Significant amounts of oxysterols have frequently been identified in foods of animal origin, in particular highly processed foods. To date, oxysterols have been shown

Epoxide hydrolases are vital to many organisms by virtue of their roles in detoxification, metabolism and processing of signaling molecules. The Mycobacterium tuberculosis genome encodes an unusually large number of epoxide hydrolases, suggesting that they might be of particular importance
