A new gaseous signaling molecule emerges: Cardioprotective role of hydrogen sulfide

Open access
Lefer, David J.·2007·Proceedings of the National Academy of Sciences

Abstract

Cardiovascular (CV) research has largely been focused on two endogenously produced gaseous signaling molecules, namely, nitric oxide (NO) and carbon monoxide (CO). These gaseous messengers are both highly conserved evolutionarily and synthesized by endogenous enzyme systems. Extensive research efforts have uniformly demonstrated that CO- and NO-based therapeutics protect the brain, heart, and circulation against a number of CV disease states (1–3). However, controversy exists regarding the therapeutic value of both CO and NO, with some studies citing NO cytotoxicity at very high levels and under certain conditions (2). The toxic effects of NO are related to the highly reactive nature of NO and its interaction with superoxide to form the potent oxidant peroxynitrite (ONOO−) (2). Very recently, a third endogenously produced gaseous signaling molecule, hydrogen sulfide (H2S), has emerged as a potentially important mediator of CV homeo stasis and cytoprotection (3). In this issue of PNAS, Benavides et al. (4) reveal that the vasculoprotective and antihypertensive effects of dietary garlic (Allium sativum) are mediated in large part via the generation of H2S.

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.
