Fig. 3

After 12 weeks, the left ventricle of the myocardium was collected. a The sample was stained with HE and photographed. Bar = 50 μm. b The ultrastructure of the myocardium was examined with transmission electron microscopy. Bar = 2 μm (upper) and 1 μm (lower). c Lactate dehydrogenase (LDH) level in the serum was detected. d Adenosine triphosphate (ATP) level in the myocardium was measured. Significance was determined by one-way ANOVA. Data are presented as the means ± SEM. **P < 0.01 vs the control group of the same genotype; #P < 0.05, ##P < 0.01 vs the DM group of WT mice, n = 8.
