Abstract

Background Endogenous hydrogen sulfide (H(2)S) is increasingly being recognized as an important gaseous physiological mediator. Accumulating evidence shows the functions of H(2)S in various models of disease, but rarely in colitis. In this study, we investigated the role of endogenous H(2)S in a dextran sodium sulfate (DSS)-induced colitis model.Methods Acute colitis was induced using 8% DSS in male BALB/c mice. The mRNA expression of cystathionine γ-lyase (CSE), the primary synthetase of H(2)S in the gastrointestinal tract, and cystathionine-β-synthetase (CBS) was measured by real-time RT-PCR. The amount of H(2)S in the colonic mucosa was measured by gas chromatography. Colitis severity was evaluated clinically, histologically, and biochemically under the condition of co-treatment with DL-propargylglycine (PAG), an irreversible CSE inhibitor, and sodium sulfide (Na(2)S), an H(2)S donor.Results The mRNA expression levels of CSE and CBS, and the H(2)S content in the colonic mucosa were increased with time after DSS administration. The disease activity index, which was determined by weight loss, stool consistency, and intestinal bleeding, increased after DSS administration. PAG significantly enhanced the increase in the disease activity index scores. PAG also significantly increased tissue-associated myeloperoxidase activity and thiobarbituric acid-reactive substances in the inflamed mucosa. Moreover, Na(2)S counteracted these effects of PAG.Conclusions Taken together, the results indicated that the inhibition of endogenous H(2)S generation caused the deterioration of DSS-induced colitis. We conclude that physiological H(2)S might act as an anti-inflammatory molecule in colitis.

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.
