Effects of oxaliplatin and tanshinone IIA on autophagy expression. A. The expression of autophagosome in different groups. B. Western blotting images shows the expression of mitochondrial function-related proteins (complex I, complex II, and cytochrome), autophagy-related LC3A/B, and related signaling proteins p-PI3K/PI3K, p-Akt/Akt, and p-mTOR/mTOR. C. Relative protein expression compared with GAPDH. *P < 0.05, **P < 0.01, ***P < 0.001.
