Outline of Final Research Achievements

Based on the redox sensors, roGFP and our developed Redoxfluor, we have created organelle-targeting super redox sensors and techniques monitoring intracellular local redox states in mammalian cells. Using these techniques, we have elucidated molecular mechanisms of abnormal redox states caused by aberrant intracellular protein metabolisms. Furthermore, we demonstrated food-derived compounds that recovered abnormal redox states as redox modulators.
