From: Enhancement of autophagy is a potential modality for tumors refractory to radiotherapy

(a) HepG2-8960-R was significantly more radioresistant than HepG2 at all doses examined. (b) The effect of RPM on radiosensitivity of HepG2 and HepG2-8960-R. RPM canceled radioresistance of HepG2-8960-R to the levels of HepG2. (c) The effect of 3-MA on radiosensitivity of HepG2 and HepG2-8960-R. HepG2 cells acquired the radioresistant phenotype by the administration of 3-MA. Mean±S.D. of three independent experiments was calculated. *P<0.05, **P<0.01
