JB induced DNA damage and S cycle arrest in MKN45 cells
The cells were incubated with or without various concentrations of JB for 24 h. (A) The cell cycle distribution was analyzed by flow cytometry after PI staining. (B) γ-H2AX foci were assessed by confocal microscopy. Data are expressed as means ± SD of three independent experiments. *P<0.05, **P<0.01 compared with the control group.
