The effect of Fucus spiralis fractions (1 mg/mL) in an oxidative stress condition promoted by H₂O₂ (0.2 mM), after 24 h of treatment, on MCF-7 cells. Results were obtained by the MTT method. Values in each column represent the mean ± standard error of the mean (SEM) of eight independent experiments. Symbols represent statistically significant differences (p < 0.05, analysis of variance (ANOVA), Dunett’s test) when compared to: * vehicle and # to H₂O₂.
