Yonemori et al. found that the expression of miR-139-5p/miR-139-3p in bladder cancer tissue is downregulated compared to normal bladder epithelia and overexpression of miR-139-5p/miR-139-3p in bladder cells significantly inhibited cell migration and invasion by targeting MMP11 [25]. The gene discussed is MMP11; the disease is urinary bladder cancer.
