Immunohistochemical staining and western blot analysis of tumor tissues derived from H22-bearing tumor mice. (A) H&E staining and immunohistochemistry staining of Ki-67, Bax, VEGF, and CD31. The scale bar is 50 µm. (B) The expression of mitochondrial apoptosis pathway-relative proteins (PARP, caspase 3, and caspase 9) evaluated by western blot. (C) Semiquantitative evaluation of the expression level of these proteins. *P < 0.05 indicates a statistically significant difference between groups.
