A subset of long non-coding RNAs (lncRNAs), categorized as miRNA-host gene lncRNAs (lnc-miRHGs), is processed to produce miRNAs and involved in cancer progression. This work aimed to investigate the influences and the molecular mechanisms of lnc-miRHGs MIR497HG in bladder cancer (BCa). The miR-497 and miR-195 were derived from MIR497HG. We identified that lnc-miRHG MIR497HG and two harbored miRNAs, miR-497 and miR-195, were downregulated in BCa by analyzing The Cancer Genome Atlas and our dataset. Silencing of MIR497HG by CRISPR/Cas13d in BCa cell line 5637 promoted cell growth, migration, and invasion in vitro. Conversely, overexpression of MIR497HG suppressed cell progression in BCa cell line T24. MiR-497/miR-195 mimics rescued significantly the oncogenic roles of knockdown of MIR497HG by CRISPR/Cas13d in BCa. Mechanistically, miR-497 and miR-195 co-ordinately suppressed multiple key components in Hippo/Yap and transforming growth factor β signaling and particularly attenuated the interaction between Yap and Smad3. In addition, E2F4 was proven to be critical for silencing MIR497HG transcription in BCa cells. In short, we propose for the first time to reveal the function and mechanisms of MIR497HG in BCa. Blocking the pathological process may be a potential strategy for the treatment of BCa.

Abstract Backgroud: The aim of this study was to investigate the relationship between the expression of tumor suppressor in lung cancer-1 (TSLC1) and miRNA-125b in bladder cancer (BC) pathogenesis. Methods: The expression of miRNA-125b,TSLC1 and p53 in BC cell line was detected by real-time quantitative RT-PCR (RT-qPCR) or western blot. Transwell migration assay was used in the in vitro migration and invison anssay. TSLC1 and p53 expression was evaluated by immunohistochemistric staining in bladder cancer tissues. Results: We showed that the expression of miRNA-125b was significantly decreased in BC cell line(T24) transfection of miR-125b inhibitor.Knockdown of miRNA-125b promoted the growth and metastasis of T24 cells,while overexpression of miRNA-125b had the opposite effects. Furthermore,TSLC1 was significantly positive correlated with miRNA-125b expression and negative correlated with p53 expression in T24 cells.TSLC1 transfection increased the expression of miRNA-125b,and inhibited BC cell migration and invasion in vitro,and promoted apoptosis. The expression of TSLC1 and p53 was opposite in bladder cancer tissues. Conclusions: Our data provided strong evidence that TSLC1 inhibited tumorigenesis and development of BC through up-regulating tumor-suppressive miRNA-125b.
