Table 2 Changes in AGS Cell Viability (MTT Assay) in Response to Oxidants and the Effects of Dietary Antioxidants

From: Dietary antioxidants protect gut epithelial cells from oxidant-induced apoptosis

Treatment Agonist Agonist + Cat's claw Agonist + Green tea Agonist + Vitamin C
H2O2 91.2 ± 3.6 104.0 ± 4.1 105 ± 3.1 89.8 ± 2.7
Peroxynitrite 86.8 ± 3.7 93.3 ± 3.1 101.0 ± 3.2 91.3 ± 2.7
DPPH 70.4 ± 1.3 74.2 ± 2.5 79.7 ± 1.8* 69.5 ± 1.4
  1. Viability was determined by the MTT assay and results are expressed as a percentage of control values (Mean ± SEM), N = 6 in each group. The * indicates a significant improvement in cell viability when compared to agonist alone (P < 0.05).
