| 1 | Twist1-induced miR-199a-3p promotes liver fibrosis by suppressing caveolin-2 and activating TGF-βpathway显示文摘The activation of hepatic stellate cells(HSCs)participates in liver fibrosis,and emerging evidences indicate that microRNAs(miRNAs)are abnormally expressed during HSC activation.However,the potential roles of miRNAs in liver fibrosis still remain elusive.Therefore,this study aimed to investigate the role of miR-199a-3p in liver fibrosis and its underlying mechanism.We found that miR-199a-3p expression was dramatically upregulated during HSC activation in vitro,and during liver fibrogenesis in CCl4-treated rats,and its liver expression was increased in the patients with cirrhosis.By the luciferase assay and RT-qPCR,we revealed that the expression of miR-199a-3p in HSCs was driven by the transcription factor Twist1 which could be further induced by TGF-βtreatment.Functional studies showed that inhibition of miR-199a-3p in both human LX2 cells and rat HSCs significantly decreased the expression of fibrotic markers,such as fibronectin and connective tissue growth factor(CTGF),whereas the forced expression of miR-199a-3p exhibited opposite effects,demonstrating the role of miR-199a-3p in promoting HSC activation.Mechanistically,miR-199a-3p plays an important role in TGF-βsignalling pathway activation through targeting CAV2 that negatively regulates the expression of transforming growth factor-beta receptor type I(TGFβRI).Importantly,administration of antagomiR-199a-3p in the CCl4-treated mice significantly ameliorated hepatic fibrosis.In conclusion,Twist1-induced miR-199a-3p mediates the activation of HSCs by suppressing CAV2 expression and subsequently increasing TGFβRI expression to promote TGF-βpathway.Our findings highlight the therapeutic potential of miR-199a-3p for hepatic fibrosis. | Xiaoxue Yang Liping Ma Rong Wei Tinghong Ye JianKang Zhou Maoyao Wen Ruoting Men Rami I.Aqeilan Yong Peng Li Yang | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 2 |
