描述 | 20(S)-hydroxyCholesterol (20α-Hydroxycholesterol) is an allosteric activator of the oncoprotein smoothened (Smo) that activates the hedgehog (Hh) signaling pathway with an EC50 of 3 μM in a gene transcription reporter assay using NIH3T3 cells[1]. Like human and mouse MSCs, 20S oxysterol expressed pro-osteogenic, pro-myogenic, and anti-adipogenic differentiation potential in cBMSCs. Moreover, 20(S)-Hydroxycholesterol induced markers of osteogenic genes and myogenic regulatory factors when exposed to cBMSCs treated with their specific medium[2]. Treatment of M2-10B4 cells with the osteogenic oxysterol 20S completely inhibited adipocyte formation induced by troglitazone after 10 days. Furthermore, 20S and Shh greatly inhibited PPARgamma2 promoter activity induced by CCAAT/enhancer-binding protein alpha overexpression[3]. |
