Effects of WG and DOX on apoptosis related signaling pathways in rat heart. (A) WG effectively improved the increased mRNA expression of Cyp D, VDAC1 and ANT1 in DOX rats, (B) the decreased expression of mitochondrial cytochrome c protein and (D) the increased the expression of cytoplasmic cytochrome c protein, the increased expression of cleaved-caspase-9/3 and the decreased expression of pro-caspase-3. (C and E) Semi quantitative analysis. The expression level of mitochondrial Cyt C specific protein was normalized to COX IV. All values are the mean ± SD. *P<0.05, **P<0.01 vs. CON; #P>0.05, ##P>0.01 vs. DOX. WG, wogonin; DOX, doxorubicin; VDAC1, voltage-dependent anion-selective channel 1; Cyp D, cyclophilin D; ANT1, adenine nucleotide transporter 1; Cyt C, cytochrome c.
