Dietary Iron Supplementation Enhances DSS-Induced Colitis and Associated Colorectal Carcinoma Development in Mice

Abstract

Chronic ulcerative colitis (UC) patients frequently require iron supplementation to remedy anemia due to blood loss. However, the effect of iron supplementation on UC-associated carcinogenesis is unknown. In this study, the effect of an iron-enriched diet on dextran sulfate sodium-induced acute and chronic colitis in mice was assessed. In a short-term study, mice administered 1% DSS in the drinking fluid and an AIN76A diet containing increasing levels of iron exhibited dose-dependent increases in the severity of acute UC as compared to mice fed a control diet. A marked increase in iron deposition on the epithelial surface of the colon and in the inflamed areas and immunostaining for iNOS and nitrotyrosine were observed in the animals supplemented with diets containing different levels of iron. In a long-term carcinogenesis experiment, a twofold iron-enriched diet significantly increased colorectal tumor incidence (14/16, 88%) as compared with animals fed the control diet (3/16, 19%; P < 0.001). The present findings have implications for the management of human UC and suggest that dietary iron can enhance UC and its associated carcinogenesis by augmenting oxidative and nitrosative stress.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
