Senescence is accompanied by oxidative stress and cardiac dysfunction, although the link between the two remains unclear. This study examined the role of antioxidant metallothionein on cardiomyocyte function, superoxide generation, the oxidative stress biomarker aconitase activity, cytochrome c release, and expression of oxidative stress-related proteins, such as the GTPase RhoA and NADPH oxidase protein p47phox in young (5–6 mo) and aged (26–28 mo) FVB wild-type and cardiac-specific metallothionein transgenic mice.
