Additionally, Sun et al.'s research has shown that Puerarin-V (a new crystal form of puerarin) can significantly reduce mitochondrial ROS production, decrease MDA levels, increase the activity of SOD and GSH in the myocardium, improve the activity of the mitochondrial electron transport chain, and enhance the mitochondrial respiratory function related to complexes I/II in DCM mice. This evidence concerns the gene SOD1 and familial dilated cardiomyopathy.
