Bladder cancer is one of the most common urogenital malignancies. However, its pathogenesis, especially molecular mechanisms remain elusive. Thus, understanding the molecular mechanisms underlying bladder cancer is important for the discovery of novel therapeutic paradigms for these diseases. In current study, we found that micro‐RNA (miR)‐190b is highly expressed in bladder cancer tissues and cells. Overexpression of miR‐190b enhanced the proliferation, growth, migration and invasion capabilities, and angiogenesis of bladder cancer cells, whereas downregulation of miR‐190b reversed these effects. Target prediction and dual luciferase reporter assays identified NLR family CARD domain containing 3 (NLRC3) as a potential target of miR‐190b. Pathway analysis indicated that miR‐190b promotes bladder cancer progression via the Wnt/β‐catenin and mTOR signaling pathways. Taken together, our findings imply that miR‐190b acts as a critical regulator for bladder cancer development by repressing NLRC3 and partly through the Wnt/β‐catenin and mTOR pathways. Our study suggests that miR‐190b may be served as a potential therapeutic target for bladder cancer treatment.
