Oxidized low density lipoprotein is a risk factor for cerebrovascular disease.Proprotein convertase subtilisin/kexin type 9(PCSK9) can increase the level of low density lipoprotein.Therefore,this study assumed that PCSK9 plays important roles in ischemic cerebrovascular disease.The present study established transient focal cerebral ischemia models after 100 minutes of middle cerebral artery occlusion.In situ hybridization demonstrated that PCSK9 mRNA expression increased gradually with prolonged reperfusion time in ischemic cortices.This indicated that transient focal cerebral ischemia upregulated PCSK9 mRNA expression in ischemic cortices.
