The apoptosis of Hep-2 cells in vivo after irradiation. (A) The detection of apoptotic cells are by TUNEL. The nuclei of apoptotic cells were stained brown as observed under light microscopy (magnification, × 400). (B) The apoptotic rate of tumor cells treated by irradiation in combination with ATM AS-ODNs was raised. * P < 0.05, the AI of tumors treated with irradiation in combination with ATM AS-ODNs compared with the untreated group and the group treated with ATM AS-ODNs alone. ** P < 0.05, compared with the other groups.
