Dihydromyricetin Protects against Diabetic Cardiomyopathy in Streptozotocin-Induced Diabetic Mice

Figure 5

Effects of DHM on cardiac apoptosis in STZ-induced diabetic mice. (a)-(b) Representative immunofluorescent images of staining with TUNEL (green), DAPI (blue), and Troponin T antibody (red) and quantification of TUNEL-positive cells. White arrows indicate apoptotic nuclei. The columns and error bars represent the means and SD (). versus CON; versus CON + DHM; versus DM. (c)-(d) Representative images of TUNEL-stained primary neonatal cardiomyocytes and quantitative analysis of the apoptotic index. White arrows indicate apoptotic nuclei. versus LG; versus LG + DHM; versus HG. The columns and error bars represent the means and SD. (e)–(j) Quantitative analysis of protein expression levels in the myocardium, with representative gel blots of caspase-3, cleaved caspase-3, caspase-9, cleaved caspase-9, Bcl-2, Bax, and β-actin. The columns and error bars represent the means and SD (). versus CON; versus CON + DHM; versus DM.
