General description

7-keto-27-hydroxycholesterol interconversion to 7β,(25R)26-dihydroxycholesterol (7β,26-diHC) is catalyzed by hydroxysteroid 11-β dehydrogenase. It is also formed by the oxidation of 7-oxocholesterol (7-OC) in the presence of enzyme by sterol 26-hydroxylase (CYP27A1).

Application

7-keto-27-hydroxycholesterol has been used as an oxysterol compound to study its interaction with smoothened (SMO) protein, as a substrate to 11β-hydroxysteroid dehydrogenases (11β-HSDs) for kinetic measurement studies,

Biochem/physiol Actions

7-keto-27-hydroxycholesterol (7-OC) acts as an agonist for the smoothened (SMO) protein of Hedgehog (Hh) signalling pathway, which is vital for proper cell differentiation in embryonic tissue. It elicits strong affinity to SMO compared to 7β,(25R)26-dihydroxycholesterol (7β,26-diHC). 7-OC is reduced to 7β,(25R)26-dihydroxycholesterol (7β,26-diHC) by reactive oxygen species (ROS).

Oxysterols previously were considered intermediates of bile acid and steroid hormone biosynthetic pathways. However, recent research has emphasized the roles of oxysterols in essential physiologic processes and in various diseases. Despite these discoveries, the metabolic pathways leading to the different
