Duodenal acidification stimulates gastric H2S release through upregulating mRNA expression of cystathionine gamma lyase
Introduction: It has been reported the alkaline response of pancreas to duodenal acidification is partly mediated through duodenal release of H2S, but till now the effect of duodenal acidification on gastric H2S release has not been investigated. Therefore, the present study designed to evaluate the effects of duodenal acidification on gastric H2S release and level of mRNA expression of cys...
متن کاملCystathionine-Gamma-Lyase Gene Deletion Protects Mice against Inflammation and Liver Sieve Injury following Polymicrobial Sepsis
BACKGROUND Hydrogen sulfide (H2S), produced by the activity of cystathionine-gamma-lyase (CSE), is a key mediator of inflammation in sepsis. The liver sinusoidal endothelial cells (LSECs) are important target and mediator of sepsis. The aim of this study was to investigate the role of CSE-derived H2S on inflammation and LSECs fenestrae in caecal-ligation and puncture (CLP)-induced sepsis using ...
متن کاملBlood pressure control: hydrogen sulfide, a new gasotransmitter, takes stage.
Hydrogen sulfide (H2S) is the most recently characterized autocrine/paracrine messenger implicated in the control of vascular tone. A series of coherent observations now document that this gas is a strong vasorelaxant and a determinant of blood pressure in experimental models. Targeted deletion of the gene encoding cystathionine-lyase (CSE). CSE, a key enzyme for H2S biosynthesis, reduces serum...

متن کاملH2S: an Endogenous Gas
Gases such as NO and CO play important roles both in normal physiology and in disease. In recent years, interest has been directed towards other naturally occurring gases, notably H 2 S, which is produced in body by three enzymes namely CBS (cystathionine beta synthase), CSE (cystathionine gamma lyase) and MST (3-Mercaptopyruvate sulfurtransferase), present in mitochondria and/or cytosols where...
