Results from Sedighi et al. showed that the serum activities of SOD, CAT, and GPX were increased and that the concentrations of MDA and lactate dehydrogenase (LDH) were decreased in the presence of CA, followed by a reduction of the infarct size, cTnI level, and duration of arrhythmias in rats suffering from myocardial I/R damage [99]. Here, SOD1 is linked to cancer.
