Hydrogen sulfide and endothelium-dependent vasorelaxation.
In addition to nitric oxide and carbon monoxide, hydrogen sulfide (H2S), synthesized enzymatically from l-cysteine or l-homocysteine, is the third gasotransmitter in mammals. Endogenous H2S is involved in the regulation of many physiological processes, including vascular tone. Although initially it was suggested that in the vascular wall H2S is synthesized only by smooth muscle cells and relaxe...
متن کاملcGMP-Dependent Protein Kinase Contributes to Hydrogen Sulfide-Stimulated Vasorelaxation
A growing body of evidence suggests that hydrogen sulfide (H₂S) is a signaling molecule in mammalian cells. In the cardiovascular system, H₂S enhances vasodilation and angiogenesis. H₂S-induced vasodilation is hypothesized to occur through ATP-sensitive potassium channels (K(ATP)); however, we recently demonstrated that it also increases cGMP levels in tissues. Herein, we studied the involvemen...
متن کاملLeptin-Induced Endothelium-Dependent Vasorelaxation of Peripheral Arteries in Lean and Obese Rats: Role of Nitric Oxide and Hydrogen Sulfide
Adipose tissue hormone leptin induces endothelium-dependent vasorelaxation mediated by nitric oxide (NO) and endothelium-derived hyperpolarizing factors (EDHF). Previously it has been demonstrated that in short-term obesity the NO-dependent and the EDHF-dependent components of vascular effect of leptin are impaired and up-regulated, respectively. Herein we examined the mechanism of the EDHF-dep...

Estrogen exerts vascular protective effects, but the underlyingmechanisms remain to be understood fully. In recent years, hydrogen sulfide (H2S) has increasingly been recognized as an important signalingmolecule in the cardiovascular system.VascularH2S is produced from L-cysteine, catalyzed by cystathionine g-lyase (CSE). In our study, apolipoprotein E (ApoE)-deficient mice were ovariectomized ...
