The microRNA-23a has limited roles in bone formation and homeostasis in vivo

Recent studies have demonstrated that some microRNAs (miRNAs) inhibit bone formation by inhibiting the translation of specific genes. Several in vitro studies have suggested that miR - 23a inhibits osteogenic differentiation by suppressing the translation of Runx2, a transcription factor essential for osteoblastogenesis, and of Sa tb2, a member of the special AT-rich binding protein family. In the…
