【 摘 要 】

Abstract Background Breast cancer is one of the most common types of cancer in women worldwide. Anti-apoptotic activity of cancer cells is considered the main reason for drug resistance in BC which reduces the 5-year survival rate of patients and is still considered the main obstacle for cancer therapy. Stigmasterol (SS) is natural phytosterols compound in the plant which has been proved to play an important role to lower cholesterol and inducing anti-inflammatory, and anticancer properties. Methods 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. Result SS significantly decreased the expression of Bcl-2 and BCL-XL genes (*P < 0.05), induced apoptosis, and reduced cell proliferation in MCF-7 cell lines. Our in vivo study also indicated that SS could inhibit tumor size after treatment with (0, 10, 20 µM) compared to the normal control. Conclusion SS can be suggested as a potential agent in BC cancer treatment or as an adjuvant based on its ability to decrease the expression of Bcl-2 and BCL-XL genes and induce apoptosis.
