WNT5A and osteoporosis: Through Western blot, siRNA silencing and luciferase reporter assay, we illuminated miR-381-3p suppresses osteogenic differentiation by concurrently targeting four essential genes of the Wnt signaling pathway: Apc, Lef1, wnt5a, and Lrp6. Notably, the mRNA of CTD-2555A7.2 repeat sequence exhibited pronounced therapeutic efficacy in ovariectomy osteoporosis models.
