Disease relevance of hydrogen sulfide


Psychiatry related information on hydrogen sulfide


High impact information on hydrogen sulfide

  • In addition, it may facilitate reactivation of PTP1B by biological thiols and signal a unique state of the protein [11].
  • Mechanistic reexamination of NO interactions with other haem proteins containing allosteric-site thiols may be warranted [12].
  • The second is to modulate increases in contraction that are dependent on reactive oxygen intermediates and which are thought to occur through reactions with regulatory thiols on the sarcoplasmic reticulum [13].
  • Mitochondrial thiols are an important target of oxidant-induced apoptosis and necrosis and are especially vulnerable to oxidation because of the relatively alkaline pH [14].
  • The redox state of the thiols (disulfide versus dithiol) appeared to be regulated by thioredoxin, which is secreted by CD4(+) T cells [15].

Chemical compound and disease context of hydrogen sulfide


Biological context of hydrogen sulfide

  • Since thiols can undergo nitrosation and the cell membrane is rich in thiol-containing proteins, we considered the possibility that membrane surface thiols may regulate cellular entry of NO [21].
  • Our results suggest that ERp57 modulates the redox state of ER facing thiols in SERCA 2b in a Ca2+-dependent manner, providing dynamic control of ER Ca2+ homeostasis [22].
  • Diamide oxidizes cellular thiols and induces oxidative stress [23].
  • This method has allowed the preparation of two mutant B1 subunits in which two of the four thiols postulated to be within the active site of the enzyme, Cys-225 and Cys-759, have been changed to serines [24].
  • Alkylation of erythrocyte thiols also promoted translocation of calpain to the membrane, especially in the presence of Ca2+ [25].

Anatomical context of hydrogen sulfide

  • The three plasma proteins may together constitute a system for linkage and transport of peptides with reactive thiols or disulfides released into the extracellular fluids [26].
  • Abnormal redox status of membrane-protein thiols in sickle erythrocytes [27].
  • We examined RBC membranes using thiol-disulfide exchange chromatography which partitions sodium dodecyl sulfate-solubilized proteins on the basis of reactive thiols, yielding gel-bound (reduced-thiol) and filtrate (oxidized/blocked-thiol) fractions [27].
  • In skeletal muscle myosin, the reactive thiols (SH1 and SH2) are close to a proposed fulcrum region that is thought to undergo a large conformational change [28].
  • Particular thiols of the myosin subfragment 1 moieties of single glycerinated muscle fibers are covalently labeled with rhodamine [29].

Associations of hydrogen sulfide with other chemical compounds


Gene context of hydrogen sulfide

  • These results demonstrate that NAC, GSH, and other thiols may control the production of both the Th2-derived cytokine IL-4 and IL-4-induced Ig in vitro and in vivo [35].
  • Indeed, exposure to a noncytotoxic concentration of HQ induced both NQO1 and soluble thiols and protected against HQ-induced apoptosis [36].
  • Circulating erythrocytes from the GSHPx-1-deficient mice exhibited a slight reduction in membrane thiols, indicating that high exposure to peroxides might occur naturally in the circulation [37].
  • In cell-free extracts, thiols quickly eliminated the SOD2 activity [38].
  • The thiol specificity of the protective activity of TSA derives from the fact that the oxidized form of TSA can be converted back to its sulfhydryl form by treatment with thiols but not by ascorbate [39].

Analytical, diagnostic and therapeutic context of hydrogen sulfide

  • High-pressure liquid chromatography of the total thiols showed that a single peak of material was elevated almost 40-fold [33].
  • Analysis of the role of free thiols in platelet aggregation suggested a thiol-independent initial ligation followed by a thiol-dependent stabilization of binding [40].
  • There is a wide range of literature on soft lithography, organic surface science (especially self-assembled monolayers of organic thiols adsorbed on gold) and microfluidics [41].
  • The state of CPR-associated thiols may be an important determinant of CPR binding under physiologic conditions other than phagocytosis [42].
  • Intracavitary chemotherapy with activated cyclophosphamides and simultaneous systemic detoxification with protector thiols in Sarcoma 180 ascites tumor [43].
