Figure 7. Cryptotanshinone (CPT) treatment adjusted p53 signaling pathway in the rat heart induced by doxorubicin. Representative blots of 14-3-3σ, p-JNK, JNK, PI3K p85, p-AKT, AKT, and GAPDH (A). Representative blots of Bax, Bak, Bim, PUMA, Bcl-2, Bcl-xl, and GAPDH (B). Representative blots of pro-caspase-3/cleaved caspase-3, pro-caspase-9/cleaved caspase-9, and GAPDH (C). Representative blots of Foxo1, p53, PCNA, and β-tubulin (D). GAPDH, β-tubulin and PCNA were used as internal reference.
