Intracellular ROS levels (A), and DSBs determined by the neutral comet assay (B) and 53BP1/γH2AX staining (C to E) in control PCCL3 cells and cells pretreated with 20 mM NAC and/or irradiated or exposed with H2O2. The data were obtained 0.5 h (the comet assay and γH2AX) or 1.5 h (53BP1) after irradiation or 10 min after addition of H2O2. *P < 0.05; **P < 0.01.
