Abstract

Nitrite represents a circulating and tissue storage form of NO whose bioactivation is mediated by the enzymatic action of xanthine oxidoreductase, nonenzymatic disproportionation, and reduction by deoxyhemoglobin, myoglobin, and tissue heme proteins. Because the rate of NO generation from nitrite is linearly dependent on reductions in oxygen and pH levels, we hypothesized that nitrite would be reduced to NO in ischemic tissue and exert NO-dependent protective effects. Solutions of sodium nitrite were administered in the setting of hepatic and cardiac ischemia-reperfusion (I/R) injury in mice. In hepatic I/R, nitrite exerted profound dose-dependent protective effects on cellular necrosis and apoptosis, with highly significant protective effects observed at near-physiological nitrite concentrations. In myocardial I/R injury, nitrite reduced cardiac infarct size by 67%. Consistent with hypoxia-dependent nitrite bioactivation, nitrite was reduced to NO, S-nitrosothiols, N-nitros-amines, and iron-nitrosylated heme proteins within 1-30 minutes of reperfusion. Nitrite-mediated protection of both the liver and the heart was dependent on NO generation and independent of eNOS and heme oxygenase-1 enzyme activities. These results suggest that nitrite is a biological storage reserve of NO subserving a critical function in tissue protection from ischemic injury. These studies reveal an unexpected and novel therapy for diseases such as myocardial infarction, organ preservation and transplantation, and shock states.

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

  • The process of nitrite limiting intimal hyperplasia was dependent on xanthine oxidoreductase (XOR).

    “Furthermore, the process was demonstrated to be dependent on xanthine oxidoreductase (XOR)”

    From Vascular effects of dietary nitrate (as found in green leafy vegetables and beetroot) via the nitrate-nitrite-nitric oxide pathway (2013) · cites this paper as [160]

    The Discussion (page unavailable) says the contribution of xanthine oxidoreductase to nitrite-mediated protection requires further study, rather than having been demonstrated as necessary. The paper studies heart and liver ischemia-reperfusion injury, not nitrite limiting intimal hyperplasia. (LLM, conf=0.86)

    Checked by a reasoning model — may be wrong.

    Experimental — accuracy not yet measured
  • Early research indicated a therapeutic role for nitric oxide in cardioprotection in myocardial infarction models, and L-arginine treatment before reperfusion was organ-protective.

    “Early research indicated a therapeutic role for nitric oxide in cardioprotection in myocardial infarction models, 135 and L-arginine treatment before reperfusion was also organ-protective.133,136,137”

    From Nitrate-Nitrite-Nitric Oxide Pathway: Implications for Anesthesiology and Intensive Care (2010) · cites this paper as [135]

    The Discussion (page not provided) reports that nitric oxide donors and the nitric oxide precursor L-arginine protect against myocardial ischemia-reperfusion injury, supporting the cardioprotective point. It does not say L-arginine was given before reperfusion; the paper specifies that timing for nitrite, while a cited reference describes L-arginine given during reperfusion. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Pre-clinical studies with nitrate or nitrite show the potential to protect against ischaemia-reperfusion injury and reduce arterial stiffness, inflammation and intimal thickness.

    “Pre-clinical studies with nitrate or nitrite also show the potential to protect against ischaemia-reperfusion injury and reduce arterial stiffness, inflammation and intimal thickness.”

    From Vascular effects of dietary nitrate (as found in green leafy vegetables and beetroot) via the nitrate-nitrite-nitric oxide pathway (2013) · cites this paper as [160]

    The Introduction and Discussion report that nitrite protected mice from hepatic and cardiac ischaemia-reperfusion injury, compared with vehicle or nitrate controls. The paper does not report reductions in arterial stiffness, inflammation or intimal thickness, and it does not establish nitrate as protective. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Chronic inhibition of XOR with allopurinol or 3 weeks of tungsten-rich diet increased intimal hyperplasia.

    “Chronic inhibition of XOR with allopurinol or 3 weeks of tungstenrich diet increased intimal hyperplasia.”

    From Vascular effects of dietary nitrate (as found in green leafy vegetables and beetroot) via the nitrate-nitrite-nitric oxide pathway (2013) · cites this paper as [160]

    The Discussion (page unavailable) mentions xanthine oxidoreductase-dependent nitrite reduction, but not chronic XOR inhibition or intimal hyperplasia. Searches for allopurinol, tungsten, and intimal hyperplasia found no passage in our copy reporting the claimed result. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • Even the late introduction of nitrite was able to reverse intimal hyperplasia.

    “Even the late introduction of nitrite was able to reverse intimal hyperplasia [160].”

    From Vascular effects of dietary nitrate (as found in green leafy vegetables and beetroot) via the nitrate-nitrite-nitric oxide pathway (2013) · cites this paper as [160]

    The Introduction describes mouse models of liver and heart ischemia-reperfusion injury, and the section ‘Intraventricular nitrite limits myocardial I/R injury’ reports reduced infarct size when nitrite was given five minutes before reperfusion. Neither section addresses intimal hyperplasia or its reversal; searches for those terms found no relevant passage in our copy. (LLM, conf=0.76)

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.
