SOD1 and acute kidney injury: Besides, compared with the Ctrl, CM injection markedly decreased the activities of SOD (p < 0.05, Figure 7B), GSH-Px (p < 0.01, Figure 7C) and CAT (p < 0.05, Figure 7D) in renal, and XP pretreatment could significantly up-regulate the level of SOD (p < 0.01, Figure 7B), GSH-Px (p < 0.01, Figure 7C), and CAT (p < 0.05, Figure 7D) in renal tissues compared with the CI-AKI group.
