Abstract

Nitric oxide has been shown to be an important signaling messenger in ischemic preconditioning (IPC). Accordingly, we investigated whether protein S -nitrosylation occurs in IPC hearts and whether S -nitrosoglutathione (GSNO) elicits similar effects on S -nitrosylation and cardioprotection. Preceding 20 minutes of no-flow ischemia and reperfusion, hearts from C57BL/6J mice were perfused in the Langendorff mode and subjected to the following conditions: (1) control perfusion; (2) IPC; or (3) 0.1 mmol/L GSNO treatment. Compared with control, IPC and GSNO significantly improved postischemic recovery of left ventricular developed pressure and reduced infarct size. IPC and GSNO both significantly increased S -nitrosothiol contents and S -nitrosylation levels of the L-type Ca 2+ channel α1 subunit in heart membrane fractions. We identified several candidate S -nitrosylated proteins by proteomic analysis following the biotin switch method, including the cardiac sarcoplasmic reticulum Ca 2+ -ATPase, α-ketoglutarate dehydrogenase, and the mitochondrial F1-ATPase α1 subunit. The activities of these enzymes were altered in a concentration-dependent manner by GSNO treatment. We further developed a 2D DyLight fluorescence difference gel electrophoresis proteomic method that used DyLight fluors and a modified biotin switch method to identify S -nitrosylated proteins. IPC and GSNO produced a similar pattern of S -nitrosylation modification and cardiac protection against ischemia/reperfusion injury, suggesting that protein S -nitrosylation may play an important cardioprotective role in heart.

  • Prior work showed that complex I is inhibited by various nitric oxide donors in vitro and that this inhibition is associated with S-nitrosation.

    “previous work has shown that complex I is inhibited by various nitric oxide donors in vitro and that this inhibition is associated with S-nitrosation2,10,11,21–24.”
  • NO· inhibits complex IV (cytochrome c oxidase) or the ATPase complex.

    “other studies have found a role for NO· in the inhibition of complex IV (cytochrome c oxidase) (97, 474) or in the ATPase complex (405).”

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.
