Effects of trolox on curcumin's cytotoxicity in MCF-7 and MDA-MB-231 cells. Cells were pre-treated with 100 µM trolox for 15 min prior to addition of increasing concentrations of curcumin. Cell viability was analyzed by the MTS assay after 72 hours of treatment. Data (mean ± SE, n = 3) are expressed as percentages of the MTS level detected in untreated control cells. * P < 0.05, compared with untreated control cells, using one-way ANOVA followed by Dunnett's analysis.
