WTAP-Mediated m6A RNA Methylation Regulates the Differentiation of Bone Marrow Mesenchymal Stem Cells via the miR-29b-3p/HDAC4 Axis.

ABSTRACT: N6-methyladenosine (m6A) methylation, a well-known modification with new epigenetic functions, has been reported to participate in the progression of osteoporosis (OP), providing novel insights into the pathogenesis of OP. However, as the key component of m6A methylation, Wilms tumor 1-associated protein (WTAP) has not been studied in OP. Here we explored the biological role and underlying mechanism of WTAP in OP and the differentiation of bone marrow mesenchymal stem cells (BMMSCs). We demonstrated that WTAP was expressed at low levels in bone specimens from patients with OP and OVX mice. Functionally, WTAP promoted osteogenic differentiation and inhibited adipogenic differentiation of BMMSCs in vitro and in vivo. In addition, microRNA-29b-3p (miR-29b-3p) was identified as a downstream ta
