Nitric oxide release accounts for the biological activity of endothelium-derived relaxing factor

Palmer, R. M. J., Ferrige, A. G., Moncada, S.·1987·Nature

Abstract

Endothelium-derived relaxing factor (EDRF) is a labile humoral agent which mediates the action of some vasodilators. Nitrovasodilators, which may act by releasing nitric oxide (NO), mimic the effect of EDRF and it has recently been suggested by Furchgott that EDRF may be NO. We have examined this suggestion by studying the release of EDRF and NO from endothelial cells in culture. No was determined as the chemiluminescent product of its reaction with ozone. The biological activity of EDRF and of NO was measured by bioassay. The relaxation of the bioassay tissues induced by EDRF was indistinguishable from that induced by NO. Both substances were equally unstable. Bradykinin caused concentration-dependent release of NO from the cells in amounts sufficient to account for the biological activity of EDRF. The relaxations induced by EDRF and NO were inhibited by haemoglobin and enhanced by superoxide dismutase to a similar degree. Thus NO released from endothelial cells is indistinguishable from EDRF in terms of biological activity, stability, and susceptibility to an inhibitor and to a potentiator. We suggest that EDRF and NO are identical.

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

  • NOX2 expression has been reported in other cell types including endothelial cells and adventitial fibroblasts.

    “NOX2 expression has been also reported in other cell types including endothelial cells and adventitial fibroblasts (376, 382, 657, 714, 715, 736, 876) (FIGURE 9, Table 5).”
  • Nitric oxide has a vasodilatory role.

    “This paper described the vasodilatory role of nitric oxide.”

    From Exerkines in health, resilience and disease (2022) · cites this paper as [179]

  • 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.
