Upregulation of miR-214 Induced Radioresistance of Osteosarcoma by Targeting PHLDA2 via PI3K/Akt Signaling
Conclusions
In summary, our results reveal that upregulation of miR-214 is a frequent event and negatively associated with PHLDA2 expression in osteosarcoma. Furthermore, miR-214 depletion enhanced apoptosis and radiosensitivity by inhibiting the Akt pathway via PHLDA2. The miR-214/PHLDA2/Akt axis provides a new avenue toward understanding the mechanism of radiosensitivity and may be a potential target for osteosarcoma intervention.
