摘要: Oxidative stress occurs as a consequence of an imbalance between the prooxidant/antioxidant systems, causing increase intracellular generation reactive oxygen species. Alternariol (AOH), mycotoxin produced by Alternaria sp. can alter action glutathione (GSH) and enzymes involved in redox system, damage to cellular macromolecules such DNA. The aims this work were determine induction oxidative antioxidant defenses relation (GSH), reductase (GR), transferase (GST), peroxidase (GPx) levels DNA Caco-2 cells derived from adenocarcinoma human colon. AOH was confirmed alteration GSH defense system after 15, 30 60 μM exposure during 24h. significantly decreased 43% treatment with compared control. activity GPx GR reduced 30% 23%, respectively AOH. GST increased (approximately 22%) AOH, while it comparison Analysis performed using Comet assay 24h, where % tail 70% 85%
