After the sacrifice of the mice, the tumor xenografts were harvested and subjected to western blot analysis, which revealed an increased apoptotic response (Bax, cleaved-caspase-9 and cleaved-PARP) and the downregulation of proapoptotic proteins (Bcl-2) (Figure 7E), similar to the in vitro analysis results. This evidence concerns the gene BCL2 and neoplasm.
