Endothelial NADPH oxidases: which NOX to target in vascular disease?

Drummond, Grant R., Sobey, Christopher G.·2014·Trends in Endocrinology & Metabolism

Abstract

NADPH oxidases (NOXs) are reactive oxygen species (ROS)-generating enzymes implicated in the pathophysiology of vascular diseases such as hypertension and stroke. Endothelial cells express four NOX isoforms including the superoxide-generating enzymes NOX1, NOX2, and NOX5 and the hydrogen peroxide-generating enzyme NOX4. Studies on arteries from patients with coronary artery disease, and in animals with experimentally induced hypertension, diabetes, or atherosclerosis, suggest that NOX1, NOX2, and NOX5 promote endothelial dysfunction, inflammation, and apoptosis in the vessel wall, whereas NOX4 is by contrast vasoprotective in increasing nitric oxide bioavailability and suppressing cell death pathways. Based on these findings and promising preclinical studies with the NOX1/NOX2 antagonist, apocynin, we suggest that the field is poised for clinical evaluation of NOX inhibitors as therapeutics for cardiovascular disease.

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?

  • In the human vasculature, the most relevant NOX isoforms appear to be NOX1, NOX2, NOX4, and NOX5.

    “In the human vasculature, the most relevant isoforms appear to be NOX1, NOX2, NOX4, and NOX5 (252, 253, 555).”
  • Mice combining the mutation of p47phox−/− with ApoE−/− appear to be protected from atherosclerotic lesions compared with ApoE−/− mice.

    “The mice combining the mutation of p47phox−/− with ApoE−/− appear to be protected from atherosclerotic lesions (253) compared with ApoE−/− mice (64, 976), although some reports do not find significant differences in atherosclerosis progression or lesion size (443).”
  • NOX4 protective role may be due to its generation of hydrogen peroxide, and not superoxide.

    “NOX4 protective role may be due to its generation of hydrogen peroxide, and not superoxide (253).”

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.
