miR-27a-3p promoted proliferation and resistance of BC cells in vitro. (A and B) qRT-PCR was performed to examine miR-27a-3p expression in MCF-7 and MCF-7/ADR cells transfected with either miR-27a-3p mimics or inhibitors. (C and D) IC50 was verified in MCF-7 and MCF-7/ADR cells transfected with either miR-27a-3p mimics or inhibitors. (E and F) Cell proliferation was determined with CCK-8 assays and colony formation assays in MCF-7 and MCF-7/ADR cells transfected with either miR-27a-3p mimics or inhibitors. *P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001. The data are expressed as mean ± SD.
