Figure 6. Selenium and GPx-1 protect MCF-7 and MCF-7GPx-1 cells against bleomycin induced cytotoxicity.

Figure 6

MCF7 (A) and MCF-7GPx-1 (B) cells were either treated or untreated with selenium for 3 days, exposed to 10μg/ml bleomycin for 1 hr and the MTT assay was performed 48 hrs after bleomycin addition. Figure C is a composite of data from A and B demonstrating the enhanced protection of selenium and GPx-1 against bleomycin toxicity. Error bars indicate the S.D. and * indicates P< 0.05 for the difference between treated and control cultures.
