Prolonged autophagy by MTOR inhibitor leads radioresistant cancer cells into senescence

Abstract excerpt

Radiotherapy is one of the well-established therapeutic modalities for cancer treatment. However, the emergence of cells refractory to radiation is a major obstacle to successful treatment with radiotherapy. Many reports suggest that inhibitors targeting the mechanistic target of rapamycin (MTOR) can sensitize cancer cells to the effect of radiation, although by which mechanism MTOR inhibitors enhance the...
