Abstract

Nitrite and nitrate are frequently used surrogate markers of nitric oxide (NO) production. Using rat models of acute and chronic DSS-induced colitis we examined the applicability of these and other NO-related metabolites, in tissues and blood, for the characterization of inflammatory bowel disease. Global NO dynamics were assessed by simultaneous quantification of nitrite, nitrate, nitroso and nitrosyl species over time in multiple compartments. NO metabolite levels were compared to a composite disease activity index (DAI) and contrasted with measurements of platelet aggregability, ascorbate redox status and the effects of 5-aminosalicylic acid (5-ASA). Nitroso products in the colon and in other organs responded in a manner consistent with the DAI. In contrast, nitrite and nitrate, in both intra- and extravascular compartments, exhibited variations that were not always in step with the DAI. Extravascular nitrite, in particular, demonstrated significant temporal instabilities, ranging from systemic drops to marked increases. The latter was particularly evident after cessation of the inflammatory stimulus and accompanied by profound ascorbate oxidation. Treatment with 5-ASA effectively reversed these fluctuations and the associated oxidative and nitrosative stress. Platelet activation was enhanced in both the acute and chronic model. Our results offer a first glimpse into the systemic nature of DSS-induced inflammation and reveal a greater complexity of NO metabolism than previously envisioned, with a clear dissociation of nitrite from other markers of NO production. The remarkable effectiveness of 5-ASA to abrogate the observed pattern of nitrite instability suggests a hitherto unrecognized role of this molecule in either development or resolution of inflammation. Its possible link to tissue oxygen consumption and the hypoxia that tends to accompany the inflammatory process warrants further investigation.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Tissue nitrite levels are repleted within four days after DSS withdrawal.

    “tissue nitrite levels were repleted within four days after DSS withdrawal that may or may not be associated with chronic inflammation.”
  • 5-aminosalicylic acid attenuates depletion of colon tissue nitrite levels, increases systemic nitrite levels, and reduces oxidative stress during DSS colitis.

    “the effects of 5-aminosalicylic acid (5-ASA- an anti-inflammatory agent for the treatment of inflammatory bowel disease) attenuated depletion of colon tissue nitrite levels, increased systemic nitrite levels, and oxidative stress during DSS colitis.”
  • The development of DSS colitis involves an early loss of colon tissue nitrite levels with a concomitant increase in systemic nitrite.

    “This study found that the development of DSS colitis involves an early loss of colon tissue nitrite levels with a concomitant increase in systemic nitrite.”

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.
