Abstract

There is mounting evidence that the established paradigm of nitric oxide (NO) biochemistry, from formation through NO synthases, over interaction with soluble guanylyl cyclase, to eventual disposal as nitrite/nitrate, represents only part of a richer chemistry through which NO elicits biological signaling. Additional pathways have been suggested that include interaction of NO-derived metabolites with thiols and metals to form S-nitrosothiols (RSNOs) and metal nitrosyls. Despite the overwhelming attention paid in this regard to RSNOs, little is known about the stability of these species, their significance outside the circulation, and whether other nitros(yl)ation products are of equal importance. We here show that N-nitrosation and heme-nitrosylation are indeed as ubiquitous as S-nitrosation in vivo and that the products of these reactions are constitutively present throughout the organ system. Our study further reveals that all NO-derived products are highly dynamic, have fairly short lifetimes, and are linked to tissue oxygenation and redox state. Experimental evidence further suggests that nitroso formation occurs substantially by means of oxidative nitrosylation rather than NO autoxidation, explaining why S-nitrosation can compete effectively with nitrosylation. Moreover, tissue nitrite can serve as a significant extravascular pool of NO during brief periods of hypoxia, and tissue nitrate/nitrite ratios can serve as indicators of the balance between local oxidative and nitrosative stress. These findings vastly expand our understanding of the fate of NO in vivo and provide a framework for further exploration of the significance of nitrosative events in redox sensing and signaling. The findings also raise the intriguing possibility that N-nitrosation is directly involved in the modulation of protein function.

Claims other papers make about this one

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

  • Tissue levels of S-nitrosothiols are enhanced through nitrite reduction due to NOS inhibition, hypoxia, and acidosis, suggesting that tissue nitrite stores can be regarded as a backup and on-demand NO donor.

    “Indeed, the tissue levels of S-nitrosothiols (NO-mediated signaling molecules) are enhanced through the nitrite reduction due to NOS inhibition, hypoxia, and acidosis [97], suggesting that the tissue nitrite stores can be regarded as a backup and on-demand NO donor.”

    From NO-Rich Diet for Lifestyle-Related Diseases (2015) · cites this paper as [97]

  • The nitrite level in cardiac tissue is a couple of times higher than in plasma due to an unknown form of active transport from blood to tissues or due to oxidation of endogenously generated NO to nitrite by ceruloplasmin, and serves as a significant extravascular pool for NO during tissue hypoxia.

    “The nitrite level in cardiac tissue is a couple of times higher than that in plasma due to an unknown form of active transport from blood to tissues or due to the oxidation of endogenously generated-NO to nitrite by ceruloplasmin [96], and serves as a significant extravascular pool for NO during tissue hypoxia [97].”

  • The speed with which nitrite affects the total vascular sulfide pool suggests a direct interaction rather than an effect of nitrite on H2S production.

    “The speed with which nitrite affects the total vascular sulfide pool suggests a direct interaction rather than an effect of nitrite on H2S production as systemic NOS inhibition is not known to lead to comparable drops in nitrite that quickly [78].”

    From On the chemical biology of the nitrite/sulfide interaction (2015) · cites this paper as [78]

  • Sulfide concentrations in rodents are higher in tissues than in blood, and the highest concentrations are observed in the vasculature, rendering the aorta a relevant target for the interaction of nitrite with sulfide.

    “As with nitrite [78], sulfide concentrations in rodents are higher in tissues than in blood, and the highest concentrations are observed in the vasculature [79], rendering the aorta a relevant target for the interaction of nitrite with sulfide.”

    From On the chemical biology of the nitrite/sulfide interaction (2015) · cites this paper as [78]

  • Intraperitoneal administration of nitrite in rats results in a rapid redistribution of this anion to all organs within 5 minutes or less.

    “intraperitoneal administration of nitrite in rats results in a rapid (≤ 5min) redistribution of this anion to all organs [50, 96].”

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.
