Effects of iron oxide nanoparticles (Fe3O4) on middle-aged liver mitochondrial respiratory chain complexes activities. (a) V max⁡ reflects complexes I, III, and IV activities and is measured using glutamate and malate. (b) V succ reflects complexes II, III, and IV activities and is measured using succinate. (c) V tmpd reflects complex IV activity and is measured using TMPD and ascorbate as mitochondrial substrates. Data are means ± SEM (one-way ANOVA followed by Tukey). *P < 0.05; **P < 0.01; ***P < 0.001 compared to control. # P < 0.05 350 μg/mL compared to 300 μg/mL. § P < 0.05 350 μg/mL compared to 250 μg/mL.
