Long non-coding RNA MIR22HG inhibits the adipogenesis of human bone marrow mesenchymal stem cells with the involvement of Wnt/ beta-catenin pathway

Osteoporosis is a frequently occurring bone remodeling disorder worldwide with one characteristic being decreasing bone mineral density and a predisposition to bone fracture, which diminishes patients' quality of life. Several studies showed that imbalance between the osteogenesis and adipogenesis of bone marrow mesenchymal stem cells (BMSCs) took part in the development of osteoporosis. In previous study, we found MIR22HG regulated the osteogenesis of human BMSCs positively. In this study, we found that MIR22HG was decreased during the adipogenesis of human BMSCs and exerted negative effects on adipogenesis with the involvement of Wnt/beta-catenin signaling pathway both in vitro and in vivo. Nitazoxanide could inhibit Wnt signaling and relieve MIR22HG's suppression on adipogenesis. These findings indicated that MIR22HG had great potential in clinical application for osteoporosis treatment and prevention.
