This study highlights that reactive lipids are not only deleterious, but they play major roles in signaling pathways as well due to their reactive, electrophile nature. WebMay 1, 2024 · A number of reactive lipid species, including 4-HNE and the cyclopentenone prostaglandin 15-deoxy-Δ(12,14)-prostaglandin J2 (15d-PGJ2), have been shown to adduct to KEAP1 cysteines and activate NRF2 target gene expression [42]. While electrophilic modification of KEAP1 is a well-established activator of the NRF2 response, a number of …
