Abstract

Blood pressure homeostasis is maintained by several mechanisms regulating cardiac output, vascular resistances, and blood volume. At cellular levels, reactive oxygen species (ROS) signaling is involved in multiple molecular mechanisms controlling blood pressure. Among ROS producing systems, NADPH oxidases (NOXs), expressed in different cells of the cardiovascular system, are the most important enzymes clearly linked to the development of hypertension. NOXs exert a central role in cardiac mechanosensing, endothelium-dependent relaxation, and Angiotensin-II (Ang-II) redox signaling regulating vascular tone. The central role of NOXs in redox-dependent cardiovascular cell functions renders these enzymes a promising pharmacological target for the treatment of cardiovascular diseases, including hypertension. The aim of the present review is to focus on the physiological role of the cardiovascular NOX-generating ROS in the molecular and cellular mechanisms affecting blood pressure.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Uncoupling of nitric oxide synthases results in a switch from nitric oxide to superoxide radical and peroxynitrite and suppressed bioavailability of nitric oxide and vasoconstriction.

    “Uncoupling of NOs results in a switch from nitric oxide to superoxide radical and peroxynitrite and suppressed bioavailability of nitric oxide and vasoconstriction (Santillo et al. 2015).”
  • Vascular NOXs are regulated by angiotensin II, which stimulates the formation of NOX-dependent ROS that in turn activate angiotensin II receptor type 1 with a self-strengthening effect.

    “Vascular NOXs are regulated by a peptide-hormone, Angiotensin II (AngII) that stimulates the formation of NOX-dependent ROS which in turn activate Angiotensin II receptor type 1 (AT1) with a self-strengthening effect (Santillo et al. 2015).”

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.
