Cell Death Dis:STAT5A的抑制通过DLX5调节促进骨生成

2018-11-17 MedSci MedSci原创

骨形成的调节对于骨形成和骨折愈合十分重要。尽管目前研究在理解成骨的分子机制方面取得了进展,但在该过程中的关键调节剂尚未得到充分表征。 在这里,我们证明抑制信号转导和转录激活因子5A(STAT5A)激活人类骨髓衍生的基质细胞(hBMSCs)中的远端同源框5(DLX5),并在体外和体内增强骨生成。结果显示,STAT5A在体外负调节Dlx5的表达,并且STAT5A缺失导致小鼠的小梁和皮质骨质量和骨矿物质

骨形成的调节对于骨形成和骨折愈合十分重要。尽管目前研究在理解成骨的分子机制方面取得了进展,但在该过程中的关键调节剂尚未得到充分表征。

在这里,我们证明抑制信号转导和转录激活因子5A(STAT5A)激活人类骨髓衍生的基质细胞(hBMSCs)中的远端同源框5(DLX5),并在体外和体内增强骨生成。结果显示,STAT5A在体外负调节Dlx5的表达,并且STAT5A缺失导致小鼠的小梁和皮质骨质量和骨矿物质密度增加。 此外,STAT5A缺失可防止与年龄相关的骨质流失。在小鼠骨折模型中,发现STAT5A缺失通过刺激骨折愈伤组织的形成明显增强骨重建。

综上所述,该研究结果表明,STAT5A抑制通过促进骨髓间充质干细胞的成骨来增强骨形成。
