Figure 7. The effect of antioxidants on clonogenic survival following treatment administration schedule 3.

Figure 7

(A) SK-N-BE(2c) cells were irradiated with 3 Gy and simultaneously treated with 0.15 μM DSF:Cu and 450 nM gemcitabine in the presence of 1 mM N-acetyl-cysteine (NAC) or 1 mM Tiron. (B) UVW cells were irradiated with 3 Gy and simultaneously treated with 0.1 μM DSF:Cu and 20 nM gemcitabine in the presence of 1 mM NAC or 1 mM Tiron. Data are means ± SEM, n=3. The independent t-test was used to compare the means of the groups treated in the absence of NAC or Tiron versus those treated in the presence of NAC or Tiron. ***P<0.001; ns, non-significant.
