Abstract

Abstract:Objective: To explore the effects of morroniside on key cell-cycle regulator proteins in a rat model of focal cerebral ischemia-reperfusion.Methods: After the model of middle cerebral artery occlusion (MCAO) was established, 15 Sprague-Dawley rats were randomly assigned into sham group, model group, morroniside low dose (30 mg·kg-1) group, morroniside middle dose (90 mg·kg-1) group and morroniside high dose (270 mg·kg-1) group. Immunohistochemistry staining was used to measure the expression of CyclinD1 and Cdk6 in ischemic ipsilateral hippocampus.Results:Compared with sham group, the expression of CyclinD1 and Cdk6 were significantly increased in vehicle-treated ischemic-reperfusion rats. However, the expression of CyclinD1 and Cdk6 was significantly reduced by treatment of morroniside at doses of 90 mg·kg-1 and 270 mg·kg-1 after ischemia-reperfusion.Conclusion: Morroniside might play a role of neuroprotection by downregulating the expression of CyclinD1 and Cdk6 after cerebral ischemia-reperfusion.

Key words:morroniside,cerebral ischemia/reperfusion,cell-cycle regulator,neuroprotective
