Hydrogen Peroxide Activates Endothelial Nitric-oxide Synthase through Coordinated Phosphorylation and Dephosphorylation via a Phosphoinositide 3-Kinase-dependent Signaling Pathway
Open accessAbstract
Endothelial nitric-oxide synthase (eNOS) is an important component of vascular homeostasis. During vascular disease, endothelial cells are exposed to excess reactive oxygen species that can alter cellular phenotype by inducing various signaling pathways. In the current study, we examined the implications of H(2)O(2)-induced signaling for eNOS phosphorylation status and activity in porcine aortic endothelial cells. We found that H(2)O(2) treatment enhanced eNOS activity and NO bioactivity as determined by the conversion of l-[(3)H]arginine to l-[(3)H]citrulline and cellular cGMP content. Concomitant with eNOS activation, H(2)O(2) also activated Akt, increased eNOS phosphorylation at Ser-1177, and decreased eNOS phosphorylation at Thr-495. H(2)O(2)-induced promotion of eNOS activity and modulation of the eNOS phosphorylation status at Ser-1177 and Thr-495 were significantly attenuated by selective inhibitors of Src kinase, the ErbB receptor family, and phosphoinositide 3-kinase (PI 3-K). We found that Akt activation, eNOS Ser-1177 phosphorylation, and eNOS activation by H(2)O(2) were calcium-dependent, whereas eNOS dephosphorylation at Thr-495 was not, suggesting a branch point in the signaling cascade downstream from PI 3-K. Consistent with this, overexpression of a dominant negative isoform of Akt inhibited H(2)O(2)-induced phosphorylation of eNOS at Ser-1177 but not dephosphorylation of eNOS at Thr-495. Together, these data indicate that H(2)O(2) promotes calcium-dependent eNOS activity through a coordinated change in the phosphorylation status of the enzyme mediated by Src- and ErbB receptor-dependent PI 3-K activation. In turn, PI 3-K mediates eNOS Ser-1177 phosphorylation via a calcium- and Akt-dependent pathway, whereas eNOS Thr-495 dephosphorylation does not involve calcium or Akt. This response may represent an attempt by endothelial cells to maintain NO bioactivity under conditions of enhanced oxidative stress.

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.
