microRNAs (miRNAs) have been demonstrated to contribute to tumor progression and metastasis and proposed to be key regulators of diverse biological processes. In this study, we report that miR-1182 is deregulated in bladder cancer tissues and cell lines. To characterize the role of miR-1182 in bladder cancer cells, we performed functional assays. The overexpression of miR-1182 significantly inhibits bladder cancer cell proliferation, colony formation, and invasion. Moreover, its up-regulation induced cell cycle arrest and apoptosis and mediated chemosensitivity to cisplatin in bladder cancer. Furthermore, a luciferase reporter assay and a rescue experiment indicated that miR-1182 directly targets hTERT by binding its 3'UTR. In conclusion, these results demonstrate that miR-1182 acts as a tumor suppressor and may be a potential biomarker for bladder cancer diagnosis and treatment. (C) 2016 Elsevier Inc.
