Abstract
Prostate cancer (PCa), which is an aggressive malignancy of the male genitourinary system. In the present study, the effects of microRNA-140 (miR-140) on PCa were determined. We transfected miR-140 mimics or negative control into PCa cells, and we used MTT, wound healing, and Transwell assays for determining the capacities of miR-140 in cell proliferation, migration, and invasion, respectively. We also confirmed the relationship between miR-140 and YES proto-oncogene 1 (YES1) using Luciferase reporter assay. The results showed that miR-140 was downregulated in PCa cells and tissues, and overexpression of miR-140 could significantly suppress their capacities of proliferation, migration, and invasion. Moreover, YES1 was shown to be a direct target of miR-140. Moreover, miR-140 expression is negatively correlated with YES1 levels. miR-140 exhibits significant tumor-suppressive effects in PCa by inhibiting YES1. The study indicated that miR-140 and YES1 could be the potential targets for PCa therapy.
