Figure 4From: 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) generation of reactive oxygene species (ROS) and, (B) p53 level in MDA-MB-231 cells. Treatment with extract produced time- and dose-dependent increases in ROS and p53. 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
