Treatment with FER and DFER for 24 h may induce cell apoptosis via the intrinsic pathway. Representative protein expressions of both (a) PARP and cleaved PARP, (b) caspase-3 and cleaved caspase-3, (c) caspase-9 and cleaved caspase-9, and quantification of Western blotting of (d–f) PARP (g,h) caspase-3 and (i,j) caspase-9 by using β-actin as internal control. Symbols (*), (**), (***) and (****) indicate significant differences (p < 0.05), (p < 0.01), (p < 0.005) and (p < 0.001), respectively, analyzed by using Student’s t-test, as compared to the control group.
