Sod2(-/-) mice are born smaller, pale and less vigorous, and die with 7-10 days. The major problems are dilated cardiomyopathy, accumulaiton of lipid in various tissues particularly liver and skeletal muscle, and metabolic acidosis [7493016]. In another strain background Sod2(-/-) mice have severe anemia, degeneration of neurons in the basal ganglia and brainstem, and progressive weakness, fatigue, and cricling behavior [8790408]. Treatment of Sod(-/-) mice with superoxide dismuate/catalase mimetics (EUK-8, EUK-134, or EUK-189) partially rescues the short lifespan (mean lifespan 14-28 days) and other phenotypes [9462746].
