The development of tamoxifen resistance commonly occurrs during the treatment of patients with breast cancer whereas its underlying mechanisms remain elusive. Here, we found that miR-24-3p regulated tamoxifen sensitivity in breast cancer cells. Forced overexpression of miR-24-3p augmented tamoxifen-induced cell viability inhibition in breast cancer cells, while knockdown of miR-24-3p partially attenuated the cytotoxicity effect of tamoxifen. Moreover, we discovered Bim as a target gene of miR-24-3p in breast cancer cells by RNA immunoprecipitation, quantitative reverse transcription polymerase chain reaction, Western blot, and dual luciferase reporter assay. In our established tamoxifen resistant MCF7 cell line (MCF7/TAM), there was a significant elevation of miR-24-3p and decrease of BIM expression compared with parental MCF7 cells. In addition, the inhibition of miR-24-3p could reverse the tamoxifen resistance of MCF7/TAM cells by the induction of cell apoptosis. Silencing of Bim expression blocked miR-24-3p inhibitor-induced elevation of tamoxifen sensitivity of MCF7/TAM cells. Using tumor tissues from patients with breast cancer, we also found that the expression of miR-24-3p was negatively correlated with Bim mRNA expression. Collectively, our study highlighted the pivotal role of miR-24-3p overexpression in mediating the development of tamoxifen resistance in breast cancer and suggested miR-24-3p might be a predictor or target for patients with breast cancer."xsd:string |
