Overview of physiologically induced oxidative stress in swine. A The increased DNA damage and oxidative stress parameters were exhibited at the end of gestation and lactation in sows. B For neonatal piglets, the highest oxidative stress parameters levels were exhibited at 1 d after birth of neonatal piglets. After that the oxidative stress parameters were reduced by the activation of Nrf2 signaling, which were reduced at 7 d after birth. C For weaned piglets, the highest oxidative stress parameters levels were exhibited at 3 d after weaning of 14 d weaned piglets. After that, the oxidative stress parameters were reduced by the activation of Nrf2 signaling. SOD: superoxide dismutase; Gpx: glutathione peroxidase; CAT: catalase; T-AOC: total antioxidant capacity; MDA: malondialdehyde; H2O2: hydrogen peroxide; ROS: reactive oxygen species; 8-OHG: 8-hydroxyguanosine; 8-OHdG: 8-hydroxy-2 deoxyguanosine; TBARS: thiobarbituric acid reactive substances; RLU: relative light unit. The data in figure are come from the references [6,7,8,9,10,11,12,13,14,15]
