From: Regulation of gene expression in chickens by heat stress
Mechanism of antioxidant enzyme systems in response to heat stress in the chicken. Production of reactive oxygen species through NOX is catalyzed to hydrogen peroxide by SOD and further broken down to the water through CAT in the presence of hydrogen ion maintained by avUCP. With the modification of the diagram [71]. NOX: nicotinamide adenine dinucleotide phosphate oxidase; SOD: Superoxide dismutase; CAT: Catalase; avUCP: Avian uncoupling protein
