This study was conducted to investigate the recovery of motor function in rats through the silent information regulator factor 2-related enzyme 1 (Sirt1) signal pathway-mediated rehabilitation training. Middle cerebral artery occlusion (MACO) was used to induce ischemia/reperfusion injury. The rats were subjected to no treatment (model), rehabilitation training (for 21 days), resveratrol (5 mg/kg for 21 days), and rehabilitation training plus resveratrol treatment. 24 h later, They were assessed for neurobehavioral score and motor behavior score and expression of brain derived-nerve neurotrophic factor (BDNF) and tyrosine kinase receptor B (TrkB). Compared with sham group, models had significantly higher neurobehavioral scores, balance beam, and rotary stick scores. Compared with the model group, rats in rehabilitation training and resveratrol groups had significantly reduced scores. Compared with rehabilitation training or resveratrol treatment alone, rehabilitation plus resveratrol further reduced the scores significantly. The percentage of cells expressing BDNF and TrkB and expression levels of BDNF and TrkB were similar between the model and sham groups, significantly increased in rehabilitation training and resveratrol groups, and further increased in rehabilitation training plus resveratrol group. These results indicate that rehabilitation raining plus resveratrol can significantly improve the recovery of motor function in rats after cerebral ischemic injury, which is likely related to the upregulation of the BDNF/TrkB signaling pathway.

Cadherin epidermal growth factor (EGF) laminin G (LAG) seven-pass G-type receptor 1 (CELSR1) is a member of a special subgroup of adhesion G protein-coupled receptors. Although Celsr1 has been reported to be a sensitive gene for stroke, the effect of CELSR1 in ischemic stroke is still not known. Here, we investigated the effect of CELSR1 on neuroprotection, neurogenesis and angiogenesis in middle cerebral artery occlusion (MCAO) rats. The mRNA expression of Celsr1 was upregulated in the subventricular zone (SVZ), hippocampus and ischemic penumbra after cerebral ischemic injury. Knocking down the expression of Celsr1 in the SVZ with a lentivirus significantly reduced the proliferation of neuroblasts, the number of CD31-positive cells, motor function and rat survival and increased cell apoptosis and the infarct volume in MCAO rats. In addition, the expression of p-PKC in the SVZ and peri-infarct tissue was downregulated after ischemia/ reperfusion. Meanwhile, in the dentate gyrus of the hippocampus, knocking down the expression of Celsr1 significantly reduced the proliferation of neuroblasts; however, it had no influence on motor function, cell apoptosis or angiogenesis. These data indicate that CELSR1 has a neuroprotective effect on cerebral ischemia injury by reducing cell apoptosis in the peri-infarct cerebral cortex and promoting neurogenesis and angiogenesis, mainly through the Wnt/PKC pathway.
