Research Abstract

Since NFATc1/NFAT2 is essential for inducing the entire processes of multinucleated cell formation, it seems to be reasonable to speculate that NFATc1 may regulate the expression of membrane proteins which control cell fusion and bone resorption. In this research, we found that 1) HB-EGF suppress osteoblast differentiation through the induction of Twist2 and suppression of nuclear translocation of Smad1, and 2) RADIO acts as a DAP12-associated receptor and is essential for the formation of functional osteoclasts through the regulation of actin-ring formation.
