Mol Ther:长非编码RNA-ORLNC1通过指导间充质干细胞转化来调节骨量

2019-01-26 MedSci MedSci原创

骨髓间充质干细胞(BMSCs)具有分化为成骨细胞或脂肪细胞的潜力,成骨和成脂分化之间的转变决定了骨量。本研究旨在确定lncRNAs是否参与骨质疏松症期间骨髓间充质干细胞的分化承诺。在这里,我们发现ORLNC1,一种高度保守的功能不确定的lncRNA,其在BMSC,骨组织和OVX诱导的骨质疏松小鼠血清中表现出显着高于假手术对应物的表达水平。值得注意的是,在骨质疏松症患者的骨组织中也观察到类似的更高丰

骨髓间充质干细胞(BMSCs)具有分化为成骨细胞或脂肪细胞的潜力,成骨和成脂分化之间的转变决定了骨量。本研究旨在确定lncRNAs是否参与骨质疏松症期间骨髓间充质干细胞的分化承诺。

在这里,我们发现ORLNC1,一种高度保守的功能不确定的lncRNA,其在BMSC,骨组织和OVX诱导的骨质疏松小鼠血清中表现出显着高于假手术对应物的表达水平。值得注意的是,在骨质疏松症患者的骨组织中也观察到类似的更高丰度的lncRNA-ORLNC1表达。过表达lncRNA-ORLNC1的转基因小鼠显示骨质疏松症相关骨丧失和BMSC成骨减少的显著增加。用过表达lncRNA-ORLNC1的慢病毒载体预处理的BMSCs表现出抑制的成骨分化能力和相反增强的脂肪形成分化。然后我们确定lncRNA-ORLNC1充当miR-296的竞争性内源RNA(ceRNA)。此外,发现miR-296在成骨细胞分化过程中明显上调,并且通过靶向Pten加速成骨分化。

总之,我们的结果表明lncRNA-ORLNC1-miR-296-Pten轴可能是骨质疏松相关的BMSC成骨和脂肪形成之间转换的关键调节因子,并且可能代表改善骨质疏松性骨丢失的合理治疗靶标。
