The levels of miR-9-5p expression and cell proliferation in DU145 and PC-3 cells transfected with an miR-9-5p inhibitor. The mRNA expression of miR-9-5p in DU145 cells (a) and PC-3 cells (b) transfected with miR-9-5p inhibitor or NC were determined using quantitative RT-PCR. DU145 cells (c) and PC-3 cells (d) were transfected with miR-9-5p inhibitor for 12, 24, 48 and 72 h, and cell proliferation was measured by CCK8 assay. *p < 0.05; **p < 0.01; ***p < 0.001 vs. NC group. All experiments were performed with at least three replicates
