摘要:
Intrauterine adhesion (IUA) is one of the most common reproductive system diseases in women worldwide. The role of lncRNAs in multiple diseases has been confirmed, but the role and mechanism of lncRNA taurine upregulated gene 1 (TUG1) in the progression of IUA need to be elucidated further. Here, we found that lncRNA TUG1 was upregulated in the endometrial tissues of IUA and TGF-β1-treated human embryonic stem cells (hESCs). Moreover, lncRNA TUG1-silenced alleviated TGF-β1-induced the proliferation and migration abilities of hESCs and enhanced inflammatory cytokines secretion in vitro. In vivo experiments showed that inhibition of lncRNA TUG1 promoted endometrium regeneration in IUA rats through downregulating inflammatory response and epithelial-to-mesenchymal transition (EMT) process. Mechanistically, lncRNA TUG1 suppression attenuated EMT process and inflammation through competitively binding miR-590-5p to downregulate Fasl expression. Collectively, our findings provide vital theoretical evidence for explaining the mechanisms of the lncRNA TUG1/miR-590-5p/Fasl axis in the progression of IUA, and may provide a new biomarker for the treatment of IUA patients. © 2020
