Early-life N-arachidonoyl-dopamine exposure increases antioxidant capacity of the brain tissues and reduces functional deficits after neonatal hypoxia in rats. Int J Dev Neurosci. 2019 Jul 29;: Authors: Sukhanova IA, Sebentsova EA, Khukhareva DD, Vysokikh MY, Bezuglov VV, Bobrov MY, Levitskaya NG Abstract Perinatal hypoxia-ischemia is one of the most common causes of perinatal brain injury and subsequent neurological disorders in children. The aim of this work was to evaluate the potential antioxidant and neuroprotective effects of N-arachidonoyl-dopamine (NADA) in the model of acute neonatal hypoxia (ANH) in rat pups. Male and female Wistar rats were exposed to a hypoxic condition (8% oxygen for 120 min) at postnatal day 2 (P2). Transcription factor HIF1-α and glutathione peroxidases GPx2 and GPx4 gene expression was increased in rat brains in the hypoxic group compared to control 1.5 h but not 4 days after ANH. There were no post-hypoxic changes in reduced (GSH) and oxidised (GSSG) glutathione levels in the brain of rat pups 1.5 h and 4 d after hypoxia. Hypoxic rats displayed retarded performance in the righting reflex and the negative geotaxis tests. ANH resulted in increased ambulation in Open field test and impaired retention in the Barnes maze task under stressful conditions as compared with the control group. Treatment with NADA significantly attenuated the delayed development of sensorimotor reflexes and stress-evoked ...
