Suppression of Excessive Histone Deacetylases Activity in Diabetic Hearts Attenuates Myocardial Ischemia/Reperfusion Injury via Mitochondria Apoptosis Pathway

Figure 4

HDAC inhibition attenuated mitochondria-associated apoptosis in diabetic rats. (a) Representative electron micrographs of each group (×7000). (b) Representative TUNEL staining images of each group. (c) Quantitative analysis of the apoptosis rate in each group. (d, e) Representative immune blot images and assessment of the cytochrome C (cytc), Bcl-2, and Bax level in each group. (f, g) Representative immune blot images and assessment of activated and inactivated caspase-3 in cardiac tissue. All results are presented as the mean ± SEM, /group. versus DIR group. versus DIR+TSA group.
