AB  - Breast cancer is the most frequently diagnosed cancer among women worldwide, and despite advances in treatment modalities, there remains a critical need for more effective therapeutic strategies. This study aimed to investigate the anti-cancer properties of Gum Arabic, a natural bioactive compound, on MCF-7 human breast cancer cells. The impact of Gum Arabic on cellular viability was assessed using an MTS assay, while its effect on long-term proliferative potential was evaluated via a colony formation assay. To determine the mode of cell death, caspase-3/7 activity assays and Annexin V-FITC/propidium iodide staining were employed. Additionally, Western blotting was conducted to analyze changes in the expression of key apoptotic proteins. The results revealed that treatment with Gum Arabic led to a dose-dependent reduction in both cell viability and colony formation ability. Moreover, apoptosis was significantly induced in the treated cells. At the molecular level, Gum Arabic administration resulted in a pronounced downregulation of the anti-apoptotic protein B-cell lymphoma 2, along with upregulation of the pro-apoptotic proteins Bcl-2-associated X and caspase-9. These findings demonstrate that Gum Arabic not only suppresses proliferation but also promotes programmed cell death in breast cancer cells through modulation of intrinsic apoptotic pathways. In conclusion, this study provides preclinical evidence supporting the potential of Gum Arabic as a promising therapeutic candidate for breast cancer treatment, warranting further investigation in advanced models and clinical settings.
