Apoptosis assay in three cells after irradiation at 48 h. Apoptosis assay of HeLa cells and the radioresistant two sub-lines 48 h after irradiation. At 0 Gy, the apoptosis rate was 0.93-2.71%for all three cell lines. The difference in the apoptosis rate between HeLa cells vs. HeLaXR and HeLaNR cells significantly increased with higher radiation doses (4 Gy: 9.32 vs 3.84, 7.94 vs 5.43; 16 Gy: 22.47 vs 7.28, 20.03 vs 11.1, p < 0.05).
