产品说明
一般描述
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).
应用
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,
生化/生理作用
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).
