The hypoxic-ischemic encephalopathy caused by peripartum asphyxia is a serious disease in newborn infants, and effective therapies need to be developed to reduce injury-related disorders. We evaluated the effects of NEP1-40 and fasudil on Nogo-A expression in neonatal hypoxic-ischemic brain damage (HIBD) rats. Seven-day-old Wistar rats were randomly divided into control, HIBD, NEP1-40, and fasudil groups. NEP1-40 and fasudil groups were injected intraperitoneally with these compounds. Rat brains at 6, 24, 72 h, and 7 days after HIBD were collected to determine histopathological damage and the expression levels of Nogo-A. Histopathological damage was reduced in NEP1-40 and fasudil groups compared with the untreated HIBD group. The expression of Nogo-A in the HIBD group was significantly higher than that in control, NEP1-40 and fasudil groups at the same times. Compared with the fasudil group, the expression levels of Nogo-A were significantly reduced in the NEP1-40 group. We conclude that NPE1-40 and fasudil have potential for neuroprotective effects in the neonatal rat HIBD model, mediated by inhibiting Nogo-A/ Rho pathways.

Hypoxic ischemic encephalopathy is a serious condition due to inadequate oxygen supply to the brain. Regeneration of neural cells is a critical process for repairing the damaged brain. Nogo has been identified as an inhibitor of neurite outgrowth that is specific to the brain. In the present study, the Nogo-A receptor (NgR) antagonist NEP1-40 was used to study the effects of inhibition of NgR on the regeneration of neural cells and the related Wnt signaling pathway in newborn rats. The investigation focused on the transcription factors regulated in the Wnt signaling pathway during the repair process, together with the proliferation of neural cells. The results indicated that c-Jun and c-Myc were the main transcription factors involved in the Wnt signaling pathway, while neural cell proliferation in the subventricular zone was increased during this process.
