Fig. 8. Illustration of the mechanism by which SIRT3 deficiency exacerbates diabetic cardiomyopathy.
SIRT3 deficiency aggravated hyperglycemia-induced mitochondrial damage, increased ROS accumulation, promoted necroptosis and cell rupture, possibly activated the NLRP3 inflammasome, and finally exacerbated diabetic cardiomyopathy in the mice.
