KEAP1 and myocardial infarction: Modification of the key reactive cysteine residues in Keap1 affects the interaction between Keap1 and its substrate nuclear factor erythroid 2-related factor 2 (Nrf2), subsequently regulating oxidative stress and NLPR3 inflammasome activation, which are important factors for myocardial ischemia-reperfusion injury (MI/RI).
