MicroRNAs (miRNAs) are small noncoding RNAs that are involved in different biological processes by suppressing target gene expression. miRNA microarray analysis revealed a significant decrease of miR-26a in prostate cancer tissues versus their normal counterparts, but the role of miR-26a is needed to investigate. In the present study, we found that miR-26a expression was lower in prostate cancer tissues compared with their normal controls, so did the prostate cancer cells. Next, by lentivirus-mediated gain-of-function studies, it was showed that stable miR-26a inhibited cell proliferation, metastasis, and epithelial mesenchymal transition and induced G1 phase arrest in prostate cancer. It was predicted that Wnt5a was a potential target gene of miR-26a by bioinformatics analysis. Then, luciferase assay and Western blot analysis identified that Wnt5a was a new direct target gene of miR-26a and miR-26a inhibited prostate cancer progression via Wnt5a. Altogether, the findings suggested that miR-26a may function as a tumor suppressor in prostate cancer by targeting Wnt5a.
