miR-4429 mimic suppresses the biological activity of PCa cells. a miR-4429 expression in DU145 and PC-3 cells introduced with miR-4429 mimic/miR-4429 inhibitor determined by RT-qPCR (unpaired t test, P < 0.0001). b PCa cell proliferation in DU145 and PC-3 cells introduced with miR-4429 mimic/miR-4429 inhibitor determined by CCK-8 assay (two-way ANOVA, P < 0.0001). c Number of colonies in DU145 and PC-3 cells introduced with miR-4429 mimic/miR-4429 inhibitor determined by colony formation assay (one-way ANOVA, P < 0.0001). d Apoptosis in DU145 and PC-3 cells introduced with miR-4429 mimic/miR-4429 inhibitor determined by flow cytometry (one-way ANOVA, P < 0.0001). e Invasion ability in DU145 and PC-3 cells introduced with miR-4429 mimic/miR-4429 inhibitor determined by Transwell assay (one-way ANOVA, P < 0.0001). Data were expressed as mean ± SD from three independent experiments. *P < 0.05 was considered to show statistical significance
