Cell viability assessed by the MTT assay, expressed as % of the control. U937 (A) and HCT116 (B) cells after 48 h of treatment with different MAGs at 5, 10, 25, 35, and 50 µg/mL. The dose-dependent decrease in cell viability can be seen as a decrease in bar height. All bars represent means ± SD with n = 3. Statistical notations: * p < 0.05; ** p < 0.01; *** p < 0.001. Note that in panel (A) all data were highly significant (p < 0.0001), but are not indicated to avoid overcrowding of symbols. Similarly, in panel (B) extremely significant differences (p < 0.0001), which are the majority, are not indicated to avoid overcrowding of symbols (ANOVA, with Tukey’s post-test).
