Exploring the molecular mechanisms that regulate the osteogenesis of human mesenchymal stem cells (hMSCs) will bring us more efficient methods for improving the treatment of bone-related diseases. In this study, we analyzed the effects of miR-31 on the osteogenesis of hMSCs. The overexpression of miR-31 repressed the osteogenesis of hMSCs, whereas the downregulation enhanced this process. SATB2 was testified to be a direct target of miR-31, and its effects on the osteogenesis were also described. Most importantly, the knockdown of SATB2 attenuated miR-31's osteogenic effects. Taken together, our findings suggest that miR-31 regulates the osteogenesis of hMSCs by targeting SATB2.
探索调控人骨髓间充质干细胞(hMSCs)成骨的分子机制,将为改善与骨相关疾病的治疗带来更有效的方法。在这项研究中,我们分析了 miR-31 对 hMSCs 成骨的影响。miR-31 的过表达抑制了 hMSCs 的成骨,而下调则增强了这一过程。SATB2 被证明是 miR-31 的一个直接靶标,其对成骨的影响也被描述。最重要的是,SATB2 的敲低减弱了 miR-31 的成骨作用。总之,我们的研究结果表明,miR-31 通过靶向 SATB2 来调节 hMSCs 的成骨。
