In bladder cancer tissues, the expression of miR-146b-5p was significantly increased compared with that in noncancerous bladder tissue, contributing to the invasive properties of bladder cancer cells by regulating ETS2 (erythroblastosis virus oncogene homolog 2) and MMP2 (matrix metalloproteinase 2) expression [21]. The gene discussed is ETS2; the disease is urinary bladder cancer.
