20(S)-Hydroxycholesterol - 1 mg

Activity: Smoothened activator . Function/Pharmacology: 20-(S)-Hydroxycholesterol is an endogenous ligand for the LXR receptor.1 It has anti-adipogenic and pro-osteogenic effects in mesenchymal stem cells mediated via a non-LXR dependent pathway.2 The osteogenic effects of 20-(S)-hydroxycholesterol have been shown to be mediated by activation of hedgehog signaling and expression of genes associated with Notch signaling.3 Activation of Hedgehog is mediated via binding of 20(S)-hydroxycholesterol to Smoothened at a site distinct from the cyclopamine binding site.4,5 Chemical Name: 5-Cholesten-3β, 20α-diol
