In this, study, we aimed to evaluate the effect of SS on the expression of anti-apoptotic genes (Bcl-2 and BCL-XL), and also evaluate its effects on cell apoptosis and cell viability using MCF-7 cell line as well as evaluating its effect on tumor growth of spontaneous breast tumor (SMMT) in vivo. This evidence concerns the gene BCL2L1 and neoplasm.
