Objective: There is a growing scientific evidence of the health-enhancing benefits of fermented food especially in cancer treatment and prevention. Fermented African locust beans (FALB) are a condiment with many medicinal activities and consume in many West African countries. Breast cancer is the most common cancer among women globally. This study investigated the cytotoxicity of FALB extracts on breast cancer (MCF-7) cells overtime and at different concentrations.
Methods: The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay was used to quantify the extent of cytotoxicity of the extracts.
Results: The aqueous extract of FALB had an half maximal inhibitory concentration (IC50) of 1.51 and 0.98 mg/mL on exposure for 24 and 48 h, respectively, against MCF-7 cells. Comparatively, the IC50 obtained for the same extract against normal human fibroblasts was 1.90 and 1.37 mg/mL, respectively.
Conclusion: The results obtained here suggest some measure of selective cytotoxicity by the aqueous extract against transformed as compared with normal cells. These findings present an important lead to the usefulness of this condiment in cancer treatment. Further studies are recommended.
