In breast cancer, prostate cancer, and other tumor diseases, miR-205 may inhibit tumor cell proliferation, invasion, and tumor growth by reversing EMT and downregulating the expression of ZEB1/2 [51–53], and it may also increase the sensitivity of tumor cells to chemotherapeutic drugs [54], thereby playing a role in tumor suppression. The gene discussed is ZEB1; the disease is Familial prostate cancer.
