Superoxide radical formation was detected using dihydroethidium (DHE) fluorescence. Results shown are the averages of for 4 experiments; error bars represent standard errors. (A) DHE fluorescence 5 minutes after 10 Gy in WT and A-T cells. Results were normalized to that of unirradiated WT cells. (B) Effect of compounds on DHE fluorescence in irradiated (10 Gy) WT cells. Results were normalized to that of unirradiated WT cells. (C) Effect of compounds treatment on DHE fluorescence in irradiated (10 Gy) A-T cells. Results were normalized to that of unirradiated A-T cells. Note antioxidant effects for MnTnHex-2-PyP and MnMx-2-PyP-Calbio on both WT and A-T cells.
