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.

Oxidized low-density lipoprotein (oxLDL) is believed to play a central role in the development of atherosclerosis. The induction of apoptosis in cells of the arterial wall is a critical event in the development of atheroma. 7beta-Hydroxycholesterol (7beta-OH) and cholesterol-5beta,6beta-epoxide (beta-epoxide)

Cholesterol epoxide hydrolase (ChEH) catalyzes the hydration of cholesterol-5,6-epoxides (5,6-EC) into cholestane-3β,5α,6β-triol. ChEH is a hetero-oligomeric complex called the anti-estrogen binding site (AEBS) comprising 3β-hydroxysterol-Δ(8)-Δ(7)-isomerase (D8D7I) and 3β-hydroxysterol-Δ(7)-reductase (DHCR7). D8D7I and DHCR7 regulate cholesterol biosynthesis, fetal development and growth, tumor

Substantial evidence suggests that oxidative modifications of low density lipoproteins (LDL) critically contribute to the pathogenesis and progression of human atherosclerosis. Oxidized LDL (oxLDL) are present in atherosclerotic plaques and contain oxysterols that exhibit a variety of adverse biological activities.
