Outline of Final Research Achievements |
Hydrogen sulfide (H2S), physiological gasseous mediator, plays important roles in regulation of the vascular tone, cytoprotection, and long-term potentiation in hippocampus. In this study, we developed sensitive and quantitative analysis method for H2S and other thiol-containing metabolites, e.g., Cysteine, Cysteine persulfide (Cys-SH), Homocysteine(Hcy), Homocysteine persulfide (Hcy-SH), reduced-glutathione, reduced-glutathione persulfide (GSSH) with mass spectrometric technologies. We tried to quantify the thiol-containing molecules in the hearts of sulfide quinone reductase-like knockdown (SQR-KD) mice using this method. SQR has been identified to be responsible for the initial oxidation of sulfide in mitochondrial matrix. We could detect the higher level of thiol-containing metabolites (H2S, Cysteine persulfide, reduced-glutathione persulfide, and Homocysteine persulfide) in the SQR-KD mice hearts compared with control mice using this useful method.
