Synergistic reduction of GSH levels. (A) MDA-MB-231 and MCF-7 cells were treated with FE or FE in combination with CDDP, TAM or TAXOL for 48 h. Total GSH levels were quantified using the GSH Assay Kit (Trevigen Inc., Gaithersburg, MD, USA); (B) MDA-MB-231 and MCF-7 cells were incubated with FE or FE in combination with CDDP, TAM or TAXOL for 48 h in the presence or absence of 5 mM GSH; cell survival was analyzed using the MTT assay. All results were obtained from three independent experiments. Differences with p < 0.05 (*) or p < 0.01 (**) were considered statistically significant.
