Anti-Atherogenic Effect of Hydrogen Sulfide by Over-Expression of Cystathionine Gamma-Lyase (CSE) Gene
Hydrogen sulfide (H2S) is an important gaseous signaling molecule that functions in physiological and pathological conditions, such as atherosclerosis. H2S dilates vessels and therefore has been suggested as an anti-atherogenic molecule. Since cystathionine gamma-lyase (CSE) enzyme is responsible for producing H2S in the cardiovascular system, we hypothesized that up-regulation of CSE expressio...
متن کاملFragment-based de novo design of a cystathionine γ-lyase selective inhibitor blocking hydrogen sulfide production
Hydrogen sulfide is an essential catabolite that intervenes in the pathophysiology of several diseases from hypertension to stroke, diabetes and pancreatitis. It is endogenously synthesized mainly by two pyridoxal-5'-phosphate-dependent enzymes involved in L-cysteine metabolism: cystathionine-ß-synthase (CBS) and cystathionine-γ-lyase (CSE). Research in this field is currently impaired by the l...
متن کاملMucosal acidification increases hydrogen sulfide release through up-regulating gene and protein expressions of cystathionine gamma-lyase in the rat gastric mucosa
Objective(s): This study was performed to investigate the effects of mucosal acidification on mRNA expression and protein synthesis of cystathionine gamma lyase (CSE), cystathionine beta synthase (CBS), and mucosal release of H2S in gastric mucosa in rats. Materials and Methods:Thirty-two rats were randomly assigned into 4 groups (8 in each), including: the control group, HCl (10 mM) treated g...
متن کاملHuman Cystathionine-β-Synthase Phosphorylation on Serine227 Modulates Hydrogen Sulfide Production in Human Urothelium
Urothelium, the epithelial lining the inner surface of human bladder, plays a key role in bladder physiology and pathology. It responds to chemical, mechanical and thermal stimuli by releasing several factors and mediators. Recently it has been shown that hydrogen sulfide contributes to human bladder homeostasis. Hydrogen sulfide is mainly produced in human bladder by the action of cystathionin...
متن کاملA cardioprotective insight of the cystathionine γ-lyase/hydrogen sulfide pathway
Traditionally, hydrogen sulfide (H2S) was simply considered as a toxic and foul smelling gas, but recently H2S been brought into the spot light of cardiovascular research and development. Since the 1990s, H2S has been mounting evidence of physiological properties such as immune modification, vascular relaxation, attenuation of oxidative stress, inflammatory mitigation, and angiogenesis. H2S has...
