miR-27a-3p directly targeted BTG2 and regulated its expression in BC cells. (A) A negative correlation was seen between the expression levels of miR-27a-3p and BTG2 in BC specimens from TCGA (r = −0.288; P < 0.05). (B) The seed sequence of miR-27a-3p is complementary to the 3ʹUTR of BTG2. (C) Luciferase activity was analyzed in MCF-7 cells transfected with miR-27a-3p mimics and miR-NC. (D) Western blot analysis demonstrated levels of BTG2 protein in MCF-7 and MCF-7/ADR cells transfected with miR-27a-3p mimics or inhibitors. (E) qRT-PCR was performed to examine the relative expression of BTG2 mRNA in MCF-7 and MCF-7/ADR cells transfected with miR-27a-3p mimics or inhibitors. **P < 0.01; ***P < 0.001. The data are expressed as mean ± SD.
