Hydrogen sulfide and polysulfides as signaling molecules
Hydrogen sulfide (H2S) is a familiar toxic gas that smells of rotten eggs. After the identification of endogenous H2S in the mammalian brain two decades ago, studies of this molecule uncovered physiological roles in processes such as neuromodulation, vascular tone regulation, cytoprotection against oxidative stress, angiogenesis, anti-inflammation, and oxygen sensing. Enzymes that produce H2S, ...
متن کاملHydrogen sulfide and polysulfides as biological mediators.
Hydrogen sulfide (H2S) is recognized as a biological mediator with various roles such as neuromodulation, regulation of the vascular tone, cytoprotection, anti-inflammation, oxygen sensing, angiogenesis, and generation of mitochondrial energy. It is produced by cystathionine β-synthase (CBS), cystathionine γ-lyase (CSE), and 3-mercaptopyruvate sulfurtransferase (3MST). The activity of CBS is en...
متن کاملHydrogen sulfide: redox metabolism and signaling.
The recognition of hydrogen sulfide (H(2)S) as an endogenously produced gas with signaling potential has stimulated research on a multitude of physiological effects mediated in the cardiovascular, immune, gastrointestinal, genitourinary, endocrine, and central nervous systems. The heightened activity in the area of H(2)S biology led to convening of the first international conference on H(2)S in...
متن کاملCalculation of the visible-UV absorption spectra of hydrogen sulfide, bisulfide, polysulfides, and As and Sb sulfides, in aqueous solution
Recently we showed that visible-UV spectra in aqueous solution can be accurately calculated for arsenic (III) bisulfides, such as As(SH)3, As(SH)2S 2 and their oligomers. The calculated lowest energy transitions for these species were diagnostic of their protonation and oligomerization state. We here extend these studies to As and Sb oxidation state III and V sulfides and to polysulfides Sn , n...
متن کاملHydrogen sulfide mediates cardioprotection through Nrf2 signaling.
RATIONALE The recent emergence of hydrogen sulfide (H(2)S) as a potent cardioprotective signaling molecule necessitates the elucidation of its cytoprotective mechanisms. OBJECTIVE The present study evaluated potential mechanisms of H(2)S-mediated cardioprotection using an in vivo model of pharmacological preconditioning. METHODS AND RESULTS H(2)S (100 microg/kg) or vehicle was administered ...
