Background: Breast cancer is the most common female cancer that, despite recent progress, its existing therapies do not have sufficient efficiency, and scientists are trying to find complementary therapies. Medicinal plants, such as pomegranate (Punica granatum L.), attract a great deal of attention in this regard. Objectives: The present study aimed to assess the anticancer effects of pomegranate peel alcoholic extract (PPE) in the mouse cellular model (4T1) of breast cancer and investigate the related molecular mechanism of antiproliferative effects of the extract through the evaluation of the expression level of apoptosis genes (ie, BAX and BCL2). Methods: For the accomplishment of the study objectives, after the preparation of PPE, an evaluation of cellular cytotoxicity was carried out using the 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay. According to the MTT assay, the cells were treated for 24 h with selective doses of the extract. Then, ribonucleic acid extraction, complementary deoxyribonucleic acid synthesis, and gene expression analysis of BAX and BCL2 using real-time polymerase chain reaction were performed in this study. Results: The results showed that PPE reduced cancer cell viability in a dose- and time-dependent manner. The molecular analysis indicated that observed cell death could be due to an increase in the BAX/BCL2 ratio. Conclusions: Overall, PPE can be proposed as a potential complementary therapy for breast cancer. However, further studies on animal models and clinical trials are needed to verify the clinical usage of such complementary drugs.
