AMP-activated kinase may suppress NADPH oxidase activation in vascular tissues

McCarty, Mark F., Barroso-Aranda, Jorge, Contreras, Francisco·2009·Medical Hypotheses

Abstract

Activation of AMP-activated kinase (AMPK) suppresses NF-kappaB-mediated transcription in endothelial cells exposed to palmitate or TNF-alpha; it also impedes angiotensin II-driven proliferation in vascular smooth muscle cells. These phenomena become predictable if we postulate that AMPK can inhibit activation of NADPH oxidase. Such an effect would make sense from a homeostatic perspective, and moreover there is direct evidence that AMPK suppresses NADPH oxidase activation in neutrophils. New evidence that sub-pathological levels of peroxynitrite can activate AMPK suggest that this enzyme may act as an "early warning signal" for oxidant stress; inhibiting NADPH oxidase would constitute a rational feedback response to such a signal.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • AMPK negatively regulates NOX by reducing its phosphorylation and preventing P47phox's translocation to membrane.

    “Additional evidence supporting AMPK protection against oxidative stress is that AMPK negatively regulates NOX by reducing its phosphorylation and preventing P47phox’s translocation to membrane [70,151].”

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.
