Dityrosine is a protein oxidation product that is formed by intermolecular cross-linking of two tyrosyl radicals generated from the interaction between reactive oxygen species (ROS) and tyrosine.1,2 Intragastric administration of dityrosine (320 μg/kg per day) decreases hippocampal expression of the NMDA receptor subunits Nr1, Nr2a, and Nr2b and induces memory impairments in a novel object recognition test in mice.2 It increases fasting blood glucose levels and decreases plasma insulin levels and pancreatic expression of the insulin synthesis-related genes Ins2, Pdx1, and MafA in mice.3 Increased levels of dityrosine are positively correlated with various diseases, including autism spectrum disorder, cataracts, Alzheimer’s disease, Parkinson’s disease, atherosclerosis, and cystic fibrosis.4,5 | [References]
