New Insights into p53 Signaling and Cancer Cell Response to DNA Damage: Implications for Cancer Therapy

Figure 3

Flow cytometric profiles of A172 cell populations before (control) and after exposure to 5 Gy or 10 Gy doses of γ radiation and incubation for the indicated times. For each sample, the adherent and floating cells were combined and analyzed as described [33]. Relative cell number is plotted as a function of fluorescence intensity. The percentage of cells with sub-G1 (apoptotic) nuclei is indicated above the marked area in each diagram.
