Abstract

The present study was designed to investigate the hypothesis that, during acetylcholine-induced endothelium-dependent relaxation, a factor(s) is released from endothelial cells which directly activates soluble guanylate cyclase. We attempted to determine what similarities or differences existed between this factor and endothelium-derived relaxing factor. The study was performed on segments of rabbit aorta and canine femoral artery. Purified soluble guanylate cyclase was injected into the lumen of these vascular segments, together with its substrate, for intraluminal incubation of the enzyme. In endothelium-intact vascular segments, the activity of guanylate cyclase was enhanced over control values obtained by incubation in test tubes. The stimulation was further increased by acetylcholine in concentrations which caused relaxation of the vascular segments. The stimulating principle could not be transferred from the vessel lumen to an external solution of guanylate cyclase, indicating a short life-time. Removal of the endothelium prevented formation and release of the guanylate cyclase stimulating factor(s). Atropine, mepacrine, or nordihydroguaiaretic acid, which inhibit acetylcholine-induced endothelium-dependent relaxations, also inhibited acetylcholine-induced endothelium-mediated activation of guanylate cyclase. The results support the hypothesis that acetylcholine-induced endothelium-derived relaxing factor increases cyclic guanosine monophosphate levels of vascular smooth muscle by a stimulation of soluble guanylate cyclase.

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

  • NO synthesized by NOS in the endothelium diffuses into the vessel wall, activates soluble guanylate cyclase in vascular smooth muscle, raises cyclic GMP, and elicits relaxation of the vessel.

    “NO synthesized by NOS in the endothelium diffuses into the vessel wall where it activates sGC in vascular smooth muscle; this leads to a rise in cyclic GMP (cGMP) and elicits relaxation of the vessel [96-102].”

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.
