Evaluation of Cytotoxic Activity of Betanin Against U87MG Human Glioma Cells and Normal Human Lymphocytes and Its Anticancer Potential Through Mitochondrial Pathway.

Recent studies revealed an antioxidant activity and anticancer efficiency of betanin. In this study, we investigated the cytotoxic effects and the possible mechanisms of betanin-induced apoptosis against U87MG human glioma cells and compared the results to those of human normal lymphocytes. MTT assay, caspase-3 activation assays in cells and succinate dehydrogenases (SDH), mitochondrial swelling, reactive oxygen species (ROS) production, mitochondrial membrane potential (MMP), and cytochrome C release assays in isolated mitochondria were obtained from U87MG human glioma cells and noncancerous human lymphocytes The results illustrated the significant cytotoxic effect of betanin on U87MG human glioma cells, with a concentration value that inhibits 50% of the cell growth of 7 µg/ml after 12 h of treatment.
