Abstract

Aberrant microRNA expression is associated with tumor development. The present study aimed to elucidate the role of miR‑30c in the development of prostate cancer. Quantitative polymerase chain reaction was performed to compare miR‑30c expression in LNCaP, DU145, PC‑3 and RWPE‑1 cell lines. Lentivirus expressing miR‑30c was used to create stable overexpression cell lines to investigate the effects of miR‑30c overexpression on cell proliferation, migration and invasion, which were determined in the prostate cancer cell line PC‑3 by MTT, colony formation, wound healing and Transwell assays. Effects of miR‑30c on KRAS were examined by western blot analysis. miR‑30c expression was significantly lower (P<0.05) in the PC‑3 cell line compared with LNCaP, DU145 and RWPE‑1 cell lines. miR‑30c overexpression in PC‑3 inhibited tumor cell proliferation, migration and invasion in vitro. Furthermore, KRAS protein expression was downregulated in miR‑30c overexpression cell lines compared with the negative control (NC) group (P<0.05). The present results demonstrated that overexpression of miR‑30c inhibits prostate cancer cell line proliferation, migration and invasion, which was possibly caused by downregulation of KRAS protein by miR‑30c. The data implicate miR‑30c in the prognosis and treatment of prostate cancer.
