Figure 3. Effect of GGA on the mitochondria-mediated apoptotic pathway.

Figure 3

(A) Western blot analysis to examine the protein levels of Bcl-2, and cytochrome c in the cytosol and mitochondria in cardiomyocytes. The protein expression of Bcl-2 (B), cytochrome c in the cytosol (C), and mitochondria (D) was analyzed using Image-Pro Plus 6.0 software and normalized to GAPDH, α-tubulin, and VDAC, respectively. (E) Effect of GGA on caspase-3 activity. A total of 20 mg protein lysate of cardiomyocytes was examined by incubation with Ac-DEVD-MCA for 5 min at 37°C. The release of 7-amino-4-methylcoumarin was measured using a spectrofluorometer. * p<0.05 and ** p<0.01.
