Effects of STS on cell viability in the presence or absence of an antioxidant NAC. a MCF-7 cells were pretreated (1 h) with NAC (1 mM) or without it. Cell viability of MCF-7 cells was measured after treatment with STS at various concentrations for 48 h. Data are presented as mean ± SD (n = 3). Statistical significance from two-way ANOVA, Tukey’s post hoc test: ***p < 0.001. b K562 cells were pretreated (1 h) with NAC (1 mM) or without it. Cell viability of K562 cells was measured after treatment with 1.2, 12, and 120 µM of STS for 48 h. Data are presented as mean ± SD (n = 4). Statistical significance from two-way ANOVA, Tukey’s post hoc test: ***p < 0.001
