Date palm (Phoenix dactylifera L.) is the most popular fruit in the Middle East and North Africa. It is consumed widely and has been used for traditional medicine purposes for a long time. The fruits are nutrient rich, containing dietary fibers, sugar, protein, vitamins, minerals, flavonoid, and phenolic compounds. Due to the presence of the phenolic compounds, date palm fruits are antioxidant rich with potent bioactivities against several bacterial pathogens. Therefore, on the basis of the available evidence as reviewed in this paper, it was found that date fruits are a good source of natural antioxidants, which can be used for the management of oxidative stress–related and infectious diseases.
Breast cancer has become a global health issue requiring huge expenditures for care and treatment of patients. There is a need to discover newer cost-effective alternatives for current therapeutic regimes. Mango kernel is a waste product with potential as a source of anti-cancer phytochemicals, especially since it is non-toxic towards normal breast cell lines at concentrations for which it induces cell death in breast cancer cells. In this study, the anti-cancer effect of mango kernel extract was determined on estrogen receptor-positive human breast carcinoma (MCF-7) cells. The MCF-7 cells were cultured and treated with 5, 10 and 50 μg/mL of mango kernel extract for 12 and 24 h. In response to treatment, there were time- and dose-dependent increases in oxidative stress markers and pro-apoptotic factors; Bcl-2-like protein 4 (BAX), p53, cytochrome c and caspases (7, 8 and 9) in the MCF-7 cells treated with the extract. At the same time, there were decreases in pro-survival markers (Bcl-2 and glutathione) as the result of the treatments. The changes induced in the MCF-7 cells by mango kernel extract treatment suggest that the extract can induce cancer cell apoptosis, likely via the activation of oxidative stress. These findings need to be evaluated further to determine whether mango kernel extract can be developed as an anti-breast cancer agent.

In this study, the effect of mango kernel extract in the induction of apoptosis of the breast cancer (MDA-MB-231) cell line was examined. This is an attempt to discover alternatives to current therapeutic regimes in the treatment of breast cancers. The pro-apoptotic markers, Bax, cytochrome c, caspases-. -8 and −9, and anti-apoptotic markers, Bcl-2, p53 and glutathione were determined in MDA-MB231 cells treated for 12 and 24 h with mango kernel extract. The results showed that the extract produced a time- and dose-dependent increases in pro-apoptotic proteins and oxidative stress markers with a corresponding decrease in anti-apoptotic markers. Based on the findings, mango kernel extract modulates redox balance in MDA-MB-231 breast cancer cells with a tendency for apoptotic cell death. The changes observed in this study may collectively underlie the basis for the cell death induced in MDA-MB-231 breast cancer cells by mango kernel extract. Thus, mango kernel extract has potential to be developed into an antibreast cancer mixture, and hence these results are worth studying further.
