MicroRNA-125b upregulation confers aromatase inhibitor resistance and is a novel marker of poor prognosis in breast cancer

Conclusion: This study highlights that acquisition of specific deregulated miRNAs is a newly discovered alternative mechanism developed by AI-resistant breast cancer cells to achieve constitutive activation of the AKT/mTOR pathway and develop AI resistance. It also highlights that miR-125b is a new biomarker of poor prognosis and a candidate therapeutic target of AI-resistant breast cancers.
