Long non‑coding RNAs (lncRNAs) have been implicated in various human malignancies, but the molecular mechanism of lncRNA TINCR ubiquitin domain containing (TINCR) in bladder cancer remains unclear. The present study found that the expression of TINCR was significantly increased in bladder cancer tissues and cell lines, when compared with that in adjacent normal tissues and normal urinary tract epithelial cell line SV‑HUC‑1, respectively. Moreover, the high expression of TINCR was associated with tumor metastasis and advanced tumor, node, metastasis stage, as well as reduced overall survival rates of patients with bladder cancer. Further investigation revealed that microRNA (miR)‑7 was negatively mediated by TINCR in bladder cancer cells. Silencing of TINCR expression significantly increased miR‑7 expression and reduced bladder cancer cell proliferation, migration and invasion, while knockdown of miR‑7 expression reversed the inhibitory effects of TINCR downregulation on bladder cancer cells. mTOR was then identified as a target gene of miR‑7 in bladder cancer, and it was demonstrated that overexpression of mTOR reversed the inhibitory effects of miR‑7 on bladder cancer cells. In conclusion, this study suggests that TINCR/miR‑7/mTOR signaling may be a potential therapeutic target for bladder cancer.
