Autophagy serves an important role in cancer cell survival and drug resistance. In the present study, the prostate cancer DU145 cell line was used, which lacks autophagy related 5 (ATG5) expression and is defective in induction of ATG5-dependent autophagy. The aim of the study was to examine the effects of the restoration of autophagy on cell proliferation and migration, and to assess the cytotoxicity caused by chemotherapeutic drugs, using microscopic, wound-healing, western blot and apoptotic assays. The restoration of the autophagic activity in DU145 cells by the overexpression of ATG5 enhanced the cell proliferation and migration rates. Notably, restoration of the ATG5-dependent autophagy in DU145 cells significantly increased the cytotoxic effects of the chemotherapeutic drugs, docetaxel and valproic acid, and the endoplasmic reticulum stress inducers, brefeldin A, tunicamycin and thapsigargin. The present study provides a novel perspective on the role of ATG5-dependent autophagy in drug resistance and chemotherapy.
