Outline of Final Research Achievements |
We utilize oxygen as a source to generate energy. In contrast, oxygen easily converts to more electrophilic substrate (electophile) and electrophile irreversibly modifies intracellular molecules, resulting in the development of diseases. We revealed that intracellular nucleophilic sulfur species (reactive persulfide species) act as chelator of electrophile to eliminate electrophilic modifications in cells. We also identified a key enzyme generating reactive persulfide species, and overexpression of this enzyme in cardiac cells was found to reduce the risk of heart failure in mice.
