From: Dietary antioxidants protect gut epithelial cells from oxidant-induced apoptosis
Apoptosis, measured as by histone-associated cytosolic DNA fragmentation, in AGS cells treated with hydrogen peroxide (50 μM) alone or in combination with cat's claw, green tea extract or ascorbic acid (10 μg/ml). The * indicates a significant reduction in apoptosis compared to hydrogen peroxide alone (P < 0.01), and † designates a significant difference between ascorbic acid and either cat's claw or green tea extract (P < 0.01).
