Expression patterns of miR-124-3p in urinary bladder cancer tissues and BCa cell lines. (A) qPCR detection of miR-124-3p in T24, UM-UC-3 and J82 cell lines versus SV-HUC-1. It was normalized with U6 snRNA in quantitative real-time RT-PCR analysis. (B) The miR-124-3p levels were determined in 10 surgical specimens of human bladder cancer tissues and were normalized to that in the adjacent normal bladder tissues, which is defined as 1. *P <0.05, **P < 0.01, ****P < 0.0001.
