Oxidant stress has been implicated in the pathogenesis of inflammatory bowel disease. Antioxidant enzymes, such as superoxide dismutase (SOD), are candidate drugs for modulating this pathogenic factor. This study was designed to determine the therapeutic value of SOD in an experimental model of colitis and to study the mechanisms underlying its effects on intestinal inflammation. For that purpose, colitic (trinitrobenzene sulfonic acid‐induced) and control rats were studied. Groups of colitic… Expand

Down‐Regulation of Endothelial Adhesion Molecules and Leukocyte Adhesion by Treatment with Superoxide Dismutase Is Beneficial in Chronic Immune Experimental Colitis
TLDR
Results indicate that SOD1 affords significant amelioration of colonic inflammatory changes in experimental colitis and down‐regulation of adhesion molecule expression, reduction of lipid hydroperoxidation, and recruitment of leukocytes into the inflamed intestine contribute to this beneficial effect. Expand
Resveratrol abrogates adhesion molecules and protects against TNBS-induced ulcerative colitis in rats.
TLDR
The study confirms the anti-ulcerative effect of resveratrol in TNBS-induced experimental colitis via reduction of neutrophil infiltration, inhibition of adhesive molecules, and restoration of the nitric oxide level, as well as the redox status. Expand
Anti-inflammatory properties of Lactobacillus gasseri expressing manganese superoxide dismutase using the interleukin 10-deficient mouse model of colitis.
TLDR
This study demonstrates that L. gasseri producing MnSOD has significant anti-inflammatory activity that reduces the severity of colitis in the IL-10-deficient mouse. Expand
Inhibition of Tumor Necrosis Factor and Nitrosative/Oxidative Stresses by Ziziphora Clinopoides (Kahlioti); A Molecular Mechanism of Protection Against Dextran Sodium Sulfate-Induced Colitis in Mice
TLDR
The present study further supports the role of oxidative/nitrosative stresses and TNF-α in the pathogenesis of colitis and protective effects of this herb and promising for further preclinical studies directed towards understanding mechanism of action andCross-species and cross-model comparisons for potential protective effects. Expand
Use of superoxide dismutase and catalase producing lactic acid bacteria in TNBS induced Crohn's disease in mice.
TLDR
The findings suggest that genetically engineered LAB that produce antioxidant enzymes could be used to prevent or decrease the severity of certain intestinal pathologies. Expand
Glutamine Treatment Attenuates Endoplasmic Reticulum Stress and Apoptosis in TNBS-Induced Colitis
TLDR
Data obtained indicated that modulation of ER stress signalling and anti-apoptotic effects contribute to protection by glutamine against damage in TNBS-induced colitis. Expand

TLDR
It is suggested that PC-SOD achieves its ameliorative effect against colitis through decreasing the colonic level of ROS and that its ineffectiveness at higher doses is because of the accumulation of hydrogen peroxide. Expand
3,3'-Diindolylmethane decreases VCAM-1 expression and alleviates experimental colitis via a BRCA1-dependent antioxidant pathway.
TLDR
3,3'-Diindolylmethane has shown anti-IBD activity in animal models by inhibiting ROS-induced VCAM-1 expression and leukocyte recruitment via a BRCA1-dependent antioxidant pathway and thus may offer potential treatments for IBD patients. Expand
Inhalation of Carbon Monoxide Ameliorates TNBS-Induced Colitis in Mice Through the Inhibition of TNF-α Expression
TLDR
The inhalation of CO protected mice from developing intestinal inflammation and the beneficial effects of CO in a murine colitis model may be attributed to its anti-inflammatory properties. Expand

Protective effects of M40403, a superoxide dismutase mimetic, in a rodent model of colitis.
TLDR
The results of this study suggested that administration of a superoxide dismutase mimetic may be beneficial for treatment of inflammatory bowel disease. Expand
Intestinal oxidative damage in inflammatory bowel disease: semi‐quantification, localization, and association with mucosal antioxidants
TLDR
The present study underlines the importance of oxidative stress in the pathogenesis of IBD and provides clues regarding the (anti)oxidants involved which indicate that this process evolves through diverging pathways in CD and UC. Expand
Regulation of Murine Intestinal Inflammation by Reactive Metabolites of Oxygen and Nitrogen
TLDR
Both the onset and severity of colitis were significantly attenuated in iNOS−/− and 1400W-treated WT mice, and divergent roles for superoxide and iN OS-derived NO in intestinal inflammation are revealed. Expand
Attenuated mild colonic inflammation and improved survival from severe DSS-colitis of transgenic Cu/Zn-SOD mice.
TLDR
These findings provide direct in vivo evidence for a protective, neutrophil-related role for Cu/Zn-SOD in intestinal inflammation and support the concept of SOD-based (adjunct) antioxidant treatment strategies for inflammatory bowel disease. Expand
The effect of antioxidant therapy on colonic inflammation in the rat
TLDR
Findings suggest that pretreatment with the antioxidants superoxide dismutase or catalase has beneficial effects on the extent of colonic inflammation, particularly in the chronic period, and this may support the importance of antioxidant therapy to reduce the severity of inflammatory bowel disease in humans. Expand
Increased oxidative stress and decreased antioxidant defenses in mucosa of inflammatory bowel disease
TLDR
An imbalance in the formation of reactive oxygen species and antioxidant micronutrients may be important in the pathogenesis and/or perpetuation of the tissue injury in IBD and may provide a rationale for therapeutic modulation with antioxidants. Expand
Differential mucosal expression of three superoxide dismutase isoforms in inflammatory bowel disease
TLDR
Mucosal tissue damage and dysfunction in chronic inflammatory bowel disease (IBD) is partly caused by an enduring exposure to excessive amounts of reactive oxygen metabolites (ROMs), and disturbance in the carefully orchestrated mucosal antioxidant cascade may contribute to the induction and perpetuation of intestinal inflammation in IBD. Expand
Imbalanced secondary mucosal antioxidant response in inflammatory bowel disease
TLDR
An imbalanced and inefficient endogenous antioxidant response in the intestinal mucosa of IBD patients is suggested, which may contribute to both the pathogenesis and the perpetuation of the inflammatory processes. Expand
Role of reactive oxygen metabolites in experimental colitis.
TLDR
The data suggest: (1) that reactive oxygen metabolites play an important role in experimental colitis, (2) that the xanthine oxidase pathway is not a major source of reactive oxygen molecules incolitis, and (3) that tissue injury in experimental Colitis is not caused by generation of hydroxyl radicals. Expand
Increases in free radicals and cytoskeletal protein oxidation and nitration in the colon of patients with inflammatory bowel disease
TLDR
Oxidant levels increase in IBD along with oxidation of tissue and cytoskeletal proteins, and marked actin oxidation—which appears to result from cumulative oxidative damage—was only seen in inflamed mucosa, suggesting that oxidant induced cytOSkeletal disruption is required for tissue injury, mucosal disruption, and IBD flare up.
