Outline of Final Research Achievements |
We have developed analytical methods of measuring lipid hydroperoxides in vivo and elucidated the link between lipid hydroperoxides and several diseases. In this study, sensitive and selective methods were established for detection of individual molecular species of fatty acid hydroperoxides and stereoisomer of phospholipid hydroperoxides. Using these methods, we clarified the mechanism for lipid oxidation induced by high-fat diet in animal study, and also revealed that ferroptosis, a newly discovered type of programmed cell death, is involved in deterioration of cell function by lipid hydroperoxides and the cell death is attenuated by α-tocopherol treatment.
