Research Abstract

We tried to address the role of miRNAs, a well-known non-coding RNAs, as a physiological regulator of bone remodeling. Through comprehensive analyses, we identified multiple miRNAs whose expression was altered during osteoblastic differentiation. Subsequently, we focused on miR-206 and demonstrated that miR-206 suppresses osteblastic differentiation by regulating connexin 43 protein expression. Thus, we uncovered that miRNA is a physiological regulator of bone remodeling.
