FOXM1 and breast carcinoma: We showed that miR-671-5p: 1) was downregulated in breast cancer; 2) suppressed proliferation and invasion of breast cells by targeting FOXM1; 3) inhibited EMT and induced S-phase arrest; and 4) sensitized breast cancer cells to cisplatin, 5-FU and epirubicin treatment by impairing DNA repair capability.
