Cerebral ischemic stroke is one of the leading causes of death and disability worldwide, and the only available drug treatment is limited to a short window following the ischemic event. Gastrodin is the major bioactive constituent extracted from thetuberGastrodia elata, and is currently used to treat dizziness in the clinic."Early"application of gastrodin (before modeling or immediately after ischemic injury) has shown antioxidative and neuroprotective effects in a transient focal brain ischemia model in rodents; however, it is not known whether the delayed administration of gastrodin after permanent focal cerebral ischemia ameliorates neural injury and increases neurogenesis. In this study, we performed a permanent middle cerebral artery occlusion (MCAO) model for the study of cerebral ischemic stroke in adult male mice to examine the effects of gastrodin. Gastrodin treatment that was started"late"(one day after the ischemic injury) significantly improved neural function, reduced infarct volume and apoptosis, and increased the number of DCX/BrdU double-positive cells in permanent MCAO mice. Moreover, gastrodin treatment markedly preserved the Wnt/β-Catenin signaling pathway, which could promote neurogenesis and provide neuroprotection brain injury. Our findings suggest that gastrodin treatment following ischemic injury can induce neuroprotection, promote neurogenesis and restored the Wnt /β-Catenin signaling pathway.
