Figure 3From: Sorafenib modulates the radio sensitivity of hepatocellular carcinoma cells in vitro in a schedule-dependent manner Effect of sorafenib on DNA damage of irradiated SMMC-7721 and BEL-7402 cells . Treated cells were stained with DAPI and anti- γ-H2AX antibody. A. Sorafenib was added to SMMC-7721 and BEL-7402 cells 30 min prior to their irradiation (6 Gy). B. Post-irradiation sorafenib treated cells were incubated for 6 h before staining. C. Percentage of cells with ≥ 10 γ-H2AX foci. Comparisons of mean values were performed using the independent two sample t test. Mean ± SD (n = 3). *P < 0.05 vs. the radiation group.Back to article page
