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 peroxynitrite (300 μM) alone or in combination with cat's claw, green tea extract or ascorbic acid (10 μg/ml). All antioxidants reduced the extent of apoptosis (*P < 0.01). However, ascorbic acid was significantly less effective than either cat's claw or green tea extract (P < 0.01).
