a Photos of subcutaneous tumors. b The tumor volumes were computed. c The body weights of the mice. d Western blot was used to detect the protein levels of PARP1, caspase 3, XIAP, Bcl-XL, PBK, and β-actin in tumor tissues. e Representative photographs of IHC staining of Ki-67, cleaved caspase 3, XIAP, Bcl-XL, and PBK in xenograft tumors. f Quantification of the protein levels in d. g Quantification of the positive ratio of Ki-67, cleaved caspase 3, XIAP, Bcl-XL, and PBK in e. Scale bar: 100 µm. (Data are presented as the mean ± SEM, #p > 0.05, *p < 0.05, **p < 0.01, n = 6).
