SOD2 and inflammatory bowel disease: The relative mRNA and protein expression levels of Cu/Zn SOD, Mn SOD, GSH-Px, and CAT in mouse colon tissues were reduced, indicating the presence of oxidative stress, while the opposite trend in mice administered with L. plantarum ZS62 indicates that L. plantarum ZS62 can prevent DSS-induced IBD by regulating oxidative stress.
