MiR-765 inhibits the osteogenic differentiation of human bone marrow mesenchymal stem cells by targeting BMP6 via regulating the BMP6/Smad1/5/9 signaling pathway.

ABSTRACT:

Background

The process of bone repair is heavily dependent on the ability of human bone marrow mesenchymal stem cells (hMSCs) to undergo osteogenic differentiation. MicroRNAs have been shown to regulate this osteogenic process. This study aimed to investigate the role of miR-765 in the osteogenic differentiation of hMSCs.

Methods

We transfected hMSCs with lentiviral constructs to knock down or overexpress this miRNA, allowing us to assess its role in osteogenesis via assessing the expression of the relevant markers alkaline phosphatase (ALP), runt-related gene-2 (RUNX-2), and osteocalcin (OCN), with further functional measurements made via quantifying ALP activity and conducting Alizarin Red S staining. The targeting of the 3'-untranslated region (UTR) of BMP6 by miR-765 was
