Abstract | AIMS: We investigated the effects of in vivo intrastriatal administration of glycine (Gly), which is found at high concentrations in the brain of patients affected by nonketotic hyperglycinemia (NKH), on important parameters of oxidative stress. MAIN METHODS: KEY FINDINGS: SIGNIFICANCE: The data shows that Gly in vivo administration causes lipid peroxidation, probably secondary to NMDA stimulation, induces protein oxidation and modulates the activities of important antioxidant enzymes in the striatum. In case these findings can be extrapolated to the human NKH, it is feasible that oxidative stress may be involved in the pathophysiology of the brain injury observed in patients with this neurometabolic disease.
