Figure 3From: Induction of apoptosis and oxidative stress in estrogen receptor-negative breast cancer, MDA-MB231 cells, by ethanolic mango seed extractEffect of mango kernel extract on (A) glutathione (GSH) and, (B) malondialdehyde (MDA) levels in MDA-MB-231 cells. Only 50 μg/mL extract decreased the level of GSH significantly (P < 0.05) significantly after 24 h, while there was a dose-dependent increase in MDA levels after 12 and 24 h. Bars with different letters for any time period of an assay indicate significant difference. *Denote significant difference at 24 h when compared to the same concentration at 12 h.Back to article page
