Abstract

To understand the role of the superoxide‐generating NADPH oxidase NOX1 in the vascular system, we have generated NOX1‐deficient mice. NOX1‐deficient mice had a moderately decreased basal blood pressure. In response to angiotensin II they showed an almost complete loss of the sustained blood pressure response, while the initial increase was conserved. NOX1‐deficient mice showed a marked reduction in aortic media hypertrophy. Angiotensin II‐induced smooth muscle cell proliferation was conserved, but there was a marked decrease in extracellular matrix accumulation. Our results establish a role for NOX1 in blood pressure regulation and vascular angiotensin II response.

  • Nox1-KO mice used were derived from at least 10 backcrosses with WT C57BL/6J mice.

    “Nox1-KO mice (Gavazzi et al., 2006) used in our experiments were derived from at least 10 backcrosses with WT C57BL/6J mice.”

  • The role of NOX1 in cardiovascular disease seems secondary to NOX2, but still significant, as shown in several models.

    “Altogether, the role of NOX1 in cardiovascular disease seems secondary to NOX2, but still significant, as shown in several models (345, 380, 630, 854).”
  • NOX1 deletion limits the blood pressure increase elicited by angiotensin II.

    “NOX1 deletion limits the blood pressure increase elicited by angiotensin II, although it is unclear if basal blood pressure levels are reduced (345, 346, 630).”
  • Nox1, 3, 4, 5, and Duox1 and 2 usually produce smaller amounts of ROS for regulation of signaling pathways or during anabolic processes.

    “Nox1, 3, 4, 5, and Duox1 and 2 usually produce smaller amounts of ROS for regulation of signaling pathways or during anabolic processes such as endothelial vasoregulation or synthesis of thyroid hormones [94,95,96,97,98].”

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.
