The effects of Apelin-13 on the behavioral and the expression of YAP in the cerebral ischemia/reperfusion injury of rats / 中华行为医学与脑科学杂志

ABSTRACT

Objective To investigate the neuroprotective effect of lateral intracerebroventricular injection of Apelin-13 on the YAP expression and the cerebral ischemia/reperfusion (I/R) injury in Wistar rats.Methods Healthy adult male Wistar rats were randomly divided into the sham group, cerebral I/R group and Apelin-13 treatment group.The middle cerebral artery occlusion model was established with ischemia for 1 hour and reperfusion for 24 hours after restricting food and water intake for 12 hours.Apelin-13 was injected into rats' lateral ventricles of Apelin-13 treatment group after reperfusion.Neural function defects was assessed.The volume of infarction was evaluated by TTC staining.The expression levels of YAP were detected by western blot.Results Compared with the cerebral I/R group,the rats in the Apelin-13 treatment group had abetter neurologic score ((2.67±0.33) vs (1.67±0.33) , P＜0.05), the infarction volume was decreased ((30.60± 1.42) ％ vs (23.70± 2.20) ％,P＜0.05) , and YAP expression level was increased in each part of the cerebral tissue(P＜0.05).Conclusion Apelin-13 has a neuroprotective effect,which plays the therapeutic effect by regulating the expression of YAP on cerebral ischemia/ reperfusion (I/R) injury in Wistar rats.
