Figure 1: Effect of NEM and buterol on DOX-induced cell death. Cell survival (% of control) after incubation for 48 h of MCF-7 cells in the presence of DOX (A), NEM (B), NEM in combination with DOX (C) and buterol separately and in combination with DOX D). After treatment with the corresponding reagents (concentrations are given in μM), cells were incubated for 48 h. The survival was determined by the MTT assay. Statistical significance *p < 0.05.
