6-keto-5α-hydroxycholesterol favors tumor progression. cholestan-6-oxo-3β,5α-diolelicits cytotoxicity towards human bronchial 16-HBE cells and plays a key role in mediating cell necrosis post ozone exposure. It is an oncometabolite, which promotes breast cancer progression and also blocks chemotaxis mediated by polymorphonuclear leukocytes.

General description

6-keto-5α-hydroxycholesterol, also known as 6-oxo-cholestan-3β,5α-diol (OCDO), is synthesized from the oxidation of 5β, 6β-epoxycholesterol in the presence of enzyme cholesterol epoxide hydrolase. It is also synthesized from cholestane-3β,5α,6β-triol by the enzyme 11β-hydroxysteroid dehydrogenase type II . The enzyme 11β-hydroxysteroid dehydrogenase type I catalyzes the reduction of OCDO to cholestane-3β,5α,6β-triol.
