NR4A3 and urinary bladder cancer: Transwell test results showed that NR4A3 overexpression inhibited the invasion ability of the bladder cancer cells, and the miR-20a-5p mimics promoted the invasion ability of the bladder cancer cells, whereas NR4A3 could reverse the invasion ability of miR-20a-5p (Figures 6(e) and 6(f)).
