タイトル CCN3/NOV inhibits BMP-2-induced osteoblast differentiation by interacting with BMP and Notch signaling pathways.
ジャーナル Biochem Biophys Res Commun
Abstract We elucidate the role of CCN3/NOV, a member of the CCN family proteins, in osteoblast differentiation using MC3T3-E1 osteoblastic cells. Transduction with CCN3 adenovirus (AdCCN3) alone induced no apparent changes in the expression of osteoblast-related markers, whereas cotransduction with BMP-2 adenovirus (AdBMP-2) and AdCCN3 significantly inhibited the AdBMP-2-induced mRNA expression of Runx2, osterix, ALP, and osteocalcin. Immunoprecipitation-western analysis revealed that CCN3 associated with BMP-2. Compared to transduction with AdBMP-2 alone, cotransduction with AdBMP-2 and AdCCN3 attenuated the expression of phosphorylated Smad1/5/8 and the mRNA for Id1, Id2, and Id3. Transduction with AdCCN3 stimulated the expression of cleaved Notch1, the mRNA expression of Hes1 and Hey1/Hesr1, and the promoter activities of Hes1 and Hey1. The inhibitory effects of CCN3 on the expression of BMP-2-induced osteoblast-related markers were nullified in Hey1-deficient osteoblastic cells. These results indicate that CCN3 exerts inhibitory effects on BMP-2-induced osteoblast differentiation by its involvement of the BMP and Notch signaling pathways.
