H₂O₂ (0.2 mM) effects on the mitochondrial membrane potential (MMP) of MCF-7 cells in the absence or presence of Fucus spiralis fractions (1 mg/mL) after 24 h of treatment. The results were obtained by the ratio between the monomers/aggregates of JC-1. The values in each column represent the mean ± standard error of the mean (SEM) of seven or eight independent experiments. Symbols represent statistically significant differences (p < 0.05, ANOVA, Dunett’s test) when compared to: * vehicle and # to H₂O₂.
