Transforming growth factor-beta 1 (TGF-β1) plays important roles in the endothelial-to-mesenchymal transition (EndMT). Recently, long noncoding RNAs (lncRNAs) have been identified to be involved in the physiological and pathological processes of human diseases. However, the role of endothelial lncRNAs in the TGF-β1-mediated control of angiogenesis and its underlying mechanism remains largely unclear. In this study, we first demonstrated that TGF-β1 induced EndMT; promoted cell viability, proliferation, migration, and tube formation of human umbilical vein endothelial cells (HUVECs). Second, our study displayed that TGF-β1 upregulated the lncRNA UCA1 expression in HUVECs, knocked down UCA1 with small interfering RNAs, and inhibited the function of TGF-β1 in HUVECs. Third, our study showed that UCA1 was located in the cytoplasm and absorbed miR-455 in TGF-β1-treated HUVECs. Further, the miR-455 inhibitor restored the role of the inhibited UCA1 in HUVECs treated with TGF-β1. Fourth, our study revealed that miR-455 inhibited ZEB1 expression, and overexpression of ZEB1 restored the role of miR-455 in HUVECs treated with TGF-β1. Finally, our study revealed that UCA1 exerted its role via regulating the UCA1/miR-455/ZEB1 regulatory axis in HUVECs treated with TGF-β1. Collectively, our study identified the role of the UCA1/miR-455/ZEB1 pathway in HUVECs treated with TGF-β1 and indicated the potential therapeutic role of this regulatory axis in angiogenesis.

TGF-β1通过UCA1 / miR-455 / ZEB1调控轴在人脐静脉内皮细胞中诱导内皮向间充质转化。

转化生长因子β1(TGF-β1)在内皮向间充质转化(EndMT)中起着重要作用。近来,已经鉴定出长的非编码RNA(lncRNA)与人类疾病的生理和病理过程有关。然而,内皮lncRNA在TGF-β1介导的血管生成控制中的作用及其基本机制仍不清楚。在这项研究中,我们首先证明了TGF-β1诱导EndMT。促进人脐静脉内皮细胞(HUVEC)的细胞活力,增殖,迁移和管形成。其次,我们的研究表明,TGF-β1上调HUVECs中lncRNA UCA1的表达,用小的干扰RNA敲低UCA1,并抑制HUVECs中TGF-β1的功能。第三,我们的研究表明,UCA1位于细胞质中,并在经TGF-β1处理的HUVEC中吸收了miR-455。此外,miR-455抑制剂在用TGF-β1处理的HUVEC中恢复了受抑制的UCA1的作用。第四,我们的研究揭示了miR-455抑制ZEB1表达,并且ZEB1的过表达恢复了miR-455在TGF-β1处理的HUVEC中的作用。最后,我们的研究表明,UCA1通过调节TGF-β1处理的HUVEC中的UCA1 / miR-455 / ZEB1调控轴发挥了作用。总体而言,我们的研究确定了UCA1 / miR-455 / ZEB1途径在TGF-β1处理的HUVEC中的作用,并指出了该调节轴在血管生成中的潜在治疗作用。我们的研究表明,miR-455抑制ZEB1表达,而ZEB1的过表达恢复了TGF-β1处理的HUVEC中miR-455的作用。最后,我们的研究表明,UCA1通过调节TGF-β1处理的HUVEC中的UCA1 / miR-455 / ZEB1调控轴发挥了作用。总体而言,我们的研究确定了UCA1 / miR-455 / ZEB1途径在TGF-β1处理的HUVEC中的作用,并指出了该调节轴在血管生成中的潜在治疗作用。我们的研究表明,miR-455抑制ZEB1表达,而ZEB1的过表达恢复了TGF-β1处理的HUVEC中miR-455的作用。最后,我们的研究表明,UCA1通过调节TGF-β1处理的HUVEC中的UCA1 / miR-455 / ZEB1调控轴发挥了作用。总体而言,我们的研究确定了UCA1 / miR-455 / ZEB1途径在TGF-β1处理的HUVEC中的作用,并指出了该调节轴在血管生成中的潜在治疗作用。
