CTNNB1 and osteoporosis: We examined the expression levels of DANCR, miR-320a and CTNNB1 in human bone marrow mesenchymal stem cells (BMSCs) derived from postmenopausal osteoporosis patients and demonstrated that miR-320a directly targeted CTNNB1 and inhibited the osteogenic differentiation of BMSCs through the Wnt/β-catenin signaling pathway.
