Estrogen exerts vascular protective effects, but the underlying mechanisms remain to be understood fully. In recent years, hydrogen sulfide (H(2)S) has increasingly been recognized as an important signaling molecule in the cardiovascular system. Vascular H(2)S is produced from L-cysteine, catalyzed

Cystathionine accumulated in several tissues of dams and fetuses by a single intraperitoneal administration of L-proparglyglycine to pregnant rats. Cystathionine in the liver of dams reached its maximal level at about 15 hrs after L-proparglyglycine injection (10 mg/300g), while that

We have previously reported that bradykinin relaxes the fetal ductus arteriosus via endothelium-derived hyperpolarizing factor (EDHF) when other naturally occurring relaxants (prostaglandin E2, nitric oxide, and carbon monoxide) are suppressed, but the identity of the agent could not be ascertained.

Hydrogen sulfide (H(2)S), which is produced endogenously from L-cysteine, is an irritant with pro-nociceptive actions. We have used measurements of intracellular calcium concentration, electrophysiology and behavioral measurements to show that the somatic pronociceptive actions of H(2)S require TRPA1. A H(2)S

Cell-selective metabolic labeling of proteins with noncanonical amino acids enables the study of proteomic changes in specified subpopulations of complex multicellular systems. For example, azidonorleucine (Anl) and 2-aminooctynoic acid, both of which are activated by an engineered methionyl-tRNA synthetase (designated

Hydrogen sulfide (H(2)S) displays vasodilative, anti-oxidative, anti-inflammatory and cytoprotective activities. Impaired production of H(2)S contributes to the increased intrahepatic resistance in cirrhotic livers. The study aimed to investigate the roles of H(2)S in carbon tetrachloride (CCl(4))-induced hepatotoxicity, cirrhosis and portal

European journal of pharmacology, 685(1-3), 165-173 (2012-05-02)
Clinical use of gentamicin over prolonged periods is limited because of dose- and time-dependent nephrotoxicity. Primarily, lysosomal phospholipidosis, intracellular oxidative stress and heightened inflammation have been implicated. Hydrogen sulphide is an endogenously produced signal transduction molecule with strong anti-inflammatory, anti-apoptotic

Hydrogen Sulfide (H2S), recently identified as the third endogenously produced gaseous messenger, is a promising therapeutic prospect for multiple cardio-pathological states, including myocardial hypertrophy. The molecular niche of H2S in normal or diseased cardiac cells is, however, sparsely understood. Here

Endogenous hydrogen sulfide is produced by cystathionine-γ-lyase and cystathionine-β-synthase in a variety of tissues and has recently been implicated in the regulation of cardiac functions. Acceleration of the heart rate in response to catecholamines is impaired in patients with cirrhosis.

A single injection of adriamycin (ADR) induces marked and persistent proteinuria in rats that progress to glomerular and tubulointerstitial lesions. It has been shown that ADR-induced nephrotoxicity is mediated, at least in part, by oxidative stress that lead to inflammation.

Lung injury induced by ischemia or reperfusion significantly accounts for the risk of early mortality of lung transplantation (LT). Recent studies have demonstrated that hydrogen sulfide (H2S) and its endogenous synthase cystathionine-γ-lyase (CSE) confer protection against injury induced by ischemia
