Figure 3

PF’s effect on apoptosis in H9c2 cells. (a) Western blot analysis was used to determine the levels of expression of apoptosis-related proteins such as bax and bcl-2. Quantification of bax and bcl-2 (b and c). The caspase-3 activity with the substrate peptide Ac-DEVD-pNA was measured using a colorimetric technique (d).
