Abstract

The anion nitrite (NO(2)(-)) constitutes a biochemical reservoir for nitric oxide (NO). Nitrite reduction to NO may be catalyzed by hemoglobin, myoglobin or other metal-containing enzymes and occurs at increasing rates under conditions of physiologic hypoxia or ischemia. A number of laboratories have now demonstrated in animal models the ability of nitrite to provide potent cytoprotection following focal ischemia-reperfusion (IR) injury of the heart, liver, brain, and kidney. While the mechanism of nitrite-mediated cytoprotection remains to be fully characterized, the release of nitrite-derived NO following IR appears to be central to this mechanism. The evidence of nitrite-mediated cytoprotection against IR injury in multiple animal models opens the door to potential therapeutic opportunities in human disease. Here we review the mechanisms for nitrite formation in blood and tissue, its metabolic equilibrium with NO, nitrate, and NO-modified proteins, the evidence supporting nitrite-mediated cytoprotection, and the potential mechanisms driving cytoprotection, and we explore the opportunities for the therapeutic application of nitrite for human disease.

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

  • Nitrite administered before or during cardiac ischemia protects cardiac function and attenuates infarct size in small and large animal models.

    “Nitrite administered before or during cardiac ischemia has been shown to protect cardiac function and attenuate infarct size in a number of small and large animal models (226, 374, 864).”
  • Nitrite is a dietary constituent that protects the heart against I/R injury in many animal models during both ischemia and preconditioning stage.

    “Nitrite is a dietary constituent that protects the heart against I/R injury in many animal models during both ischemia and preconditioning stage [186,187,188,189,190,191,192].”

    From AMPK, Mitochondrial Function, and Cardiovascular Disease (2020) · cites this paper as [189]

  • Nitrite or nitrate have been associated with beneficial effects including protection against ischemia-reperfusion injury, vasorelaxant properties, pulmonary vasodilator effects, and antihypertensive effects in experimental and clinical studies.

    “relevant biological effects were associated with nitrite or nitrate, including beneficial effects against ischemia-reperfusion injury [11,18,19], vasorelaxant properties [20], pulmonary vasodilator effects [21][22][23], and antihypertensive effects in experimental [24][25][26][27] and in clinical studies [28][29][30].”

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.
