Abstract:
Objective:To observe the effects of acupuncture on the expression of circRNA_011989 and circRNA_009775 in the hippocampal tissue of cerebral ischemia/reperfusion injury(CIRI)rats.Methods:CIRI model rats were prepared by the thread bolus method and treated by means of acupuncture(AC).The Garcia score was used to assess the neurological function.TTC staining was used to detect the volume ratio of cerebral infarction.The target prediction website was used to predict the miRNAs and corresponding mRNAs bound by circRNA_011989 and circRNA_009775,and Cytoscape was used to construct the circRNA-miRNA-mRNA co-expression network.The expression of circRNA_011989,circRNA_009775,miR-466b-5p,miR-3065-3p,Rims1,and Slc30a3 in the hippocampal region of the ische-mic side was detected by real time RT-PCR.Results:Compared with CIRI group,Garcia score of rats in CIRI+AC group was significantly increased(P＜0.01),and the infarct volume decreased.The expressions of circRNA_011989,circRNA_009775,Rims1,and Slc30a3 in right hippocampus were up-regulated(P＜0.05,P＜0.01),but the miR-466b-5p and miR-3065-3p were down-regulated(P＜0.05).Conclusion:Acupuncture may significantly ameliorate the neurological deficit symptoms in CIRI rats by upregulating the expression of circRNA_011989 and circRNA_009775,and the specific mechanism may be related to the activation of circRNA_011989/miR-466b-5p/Rim.s1 and circRNA_009775/miR-3065-3p/Slc30a3 axis related.
