• Beschreibung

  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
