Abstract

Hydrogen sulfide (H 2 S) is synthesized by 2 enzymes, cystathionine β-synthase (CBS) and cystathionine γ-lyase (CSE). l -Cysteine ( l -Cys) acts as a natural substrate for the synthesis of H 2 S. Human penile tissue possesses both CBS and CSE, and tissue homogenates efficiently convert l -Cys to H 2 S. CBS and CSE are localized in the muscular trabeculae and the smooth-muscle component of the penile artery, whereas CSE but not CBS is also expressed in peripheral nerves. Exogenous H 2 S [sodium hydrogen sulfide (NaHS)] or l -Cys causes a concentration-dependent relaxation of strips of human corpus cavernosum. l -Cys relaxation is inhibited by the CBS inhibitor, aminoxyacetic acid (AOAA). Electrical field stimulation of human penile tissue, under resting conditions, causes an increase in tension that is significantly potentiated by either propargylglycine (PAG; CSE inhibitor) or AOAA. In rats, NaHS and l -Cys promote penile erection, and the response to l -Cys is blocked by PAG. Our data demonstrate that the l -Cys/H 2 S pathway mediates human corpus cavernosum smooth-muscle relaxation.

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.
