越来越多的证据表明,长链非编码RNA(lncRNA)在肾脏疾病中起着重要作用。在这项研究中,我们研究了lncRNA生长抑制特异性5(GAS 5)在肾纤维化发病机制中的作用。我们发现,GAS 5显着减少,在纤维化的肾脏单侧输尿管梗阻(UUO)肾病小鼠模型,通过使用实时PCR。此外,GAS 5在小鼠肾小管上皮细胞(mTEC)和正常肾组织的间质成纤维细胞中表达,尤其是在细胞质中高度表达。体外实验表明TGF-β 1以剂量和时间依赖性方式下调GAS 5。GAS 5的过表达阻断TGF-β 1诱导的I型胶原和纤连蛋白的表达,反之亦然。机制研究表明,Smad 3,而不是Smad 2驱动GAS 5的调节。更重要的是,GAS 5与miR-142- 5 p相互作用,并通过参与竞争性内源性RNA(ceRNA)网络参与肾脏保护作用。最后,我们还发现GAS 5的敲低通过Smad 3途径促进TGF-β1诱导的mTEC凋亡。总之,我们的研究结果揭示了一种基于lncRNA/miRNA ceRNA网络的机制,该机制通过Smad 3途径调节细胞外基质形成和细胞凋亡。
Increasing evidence shows that long noncoding RNAs (lncRNAs) play an important role in kidney disease. In this study, we investigated the role of lncRNA growth arrest-specific 5 (GAS5) in the pathogenesis of renal fibrosis. We found that GAS5 was markedly decreased in the fibrotic kidney of a unilateral ureteral obstructive (UUO) nephropathy mouse model by using real-time PCR. In addition, GAS5 was expressed in mouse tubular epithelial cells (mTECs) and interstitial fibroblasts in normal renal tissue and was especially highly expressed in the cytoplasm. In vitro experiments showed that GAS5 was downregulated by TGF-b1 in a dose- and time-dependent manner. Overexpression of GAS5 blocked TGF-b1-induced collagen I and fibronectin expression and vice versa. Mechanistic studies revealed that Smad3 but not Smad2 drove the regulation of GAS5. More importantly, GAS5 interacted with miR-142-5p and was involved in the renoprotective effect by participating in the competing endogenous RNA (ceRNA) network. Finally, we also found that knockdown of GAS5 promoted TGF-β1-induced mTEC apoptosis via the Smad3 pathway. Taken together, our results have uncovered a lncRNA/miRNA ceRNA network-based mechanism that modulates extracellular matrix formation and cell apoptosis via the Smad3 pathway.
