Both groups received identical diet but an iron supplement (180 mg of ferrous sulfate per kg of diet) was added for the control group.
Cytochrome c oxidase activity was significantly reduced only at 14 weeks as were the concentrations of cytochromes a3, c1, and b.

Kidney and liver tissues were excised at the end of the study for assaying enzymatic activities of isocitrate dehydrogenase, succinate dehydrogenase, malate dehydrogenase, NADH-dehydrogenase and cytochrome-c-oxidase.

To evaluate the antioxidant ability of Se-2F3-scFv, we constructed a ferrous sulfate/ascorbate (Vc/Fe2+)-induced mitochondrial damage model system and investigated the capacity of Se-2F3-scFv to protect mitochondria from oxidative damage.
Se-2F3-scFv markedly decreased mitochondrial swelling, inhibited lipid peroxidation, and maintained the activity of cytochrome c oxidase, in comparison with Ebselen, a well-studied glutathione peroxidase mimic, indicating that Se-2F3-scFv has potential for treating diseases mediated by ROS.

Deletion of YDL120, the yeast homologue of the human gene responsible for Friedreich's ataxia, elicits decreased cellular respiration associated with decreased cytochrome c oxidase activity and, in certain nuclear backgrounds, mitochondrial DNA is lost.
However, only ferrous sulfate elicits loss of mitochondrial DNA.

The antioxidant activity of a novel artificial glutathione peroxidase-like enzyme, selenium-containing glutathione 5-transferase from Lucilia cuprina (seleno-LuGST1-1), was studied by using a ferrous sulfate/ascorbate-induced mitochondrial damage model system.
Swelling of mitochondria, lipid peroxidation, and cytochrome-c oxidase activity were selected to evaluate the preservation of mitochondrial integrity in this system.
