Effects of ATG and AF on cell viability and TrxR activity in HeLa cells.
A, HeLa cells were treated with different concentrations of ATG or AF for 24, 48, and 72 h. Cell viability was determined with the MTT assay. Error bars show mean ± S.D. B and C, HeLa cells were treated with different concentrations of ATG (B) or AF (C) for 24 h. After treatment, TrxR activities were determined with the fluorescent insulin assay. Error bars show mean ± S.D. n = 2; *, p < 0.05, Student's t test, ATG or AF treated cells versus control.
