OBJECTIVES: To explore the mechanisms of acupuncture against cerebral ischemia/reperfusion injury (CIRI) through observing the expression of circular RNA HDAC2 (circHDAC2) in the hippocampus of rats. METHODS: value, fold change (FC) and gene ontology (GO) analysis；and their expressions in the ischemic hippocampus were determined using quantitative real-time PCR (qPCR). Based on the verification results, a competing endogenous RNA (ceRNA) prediction network was constructed. The expression levels of microRNA (miRNA) and mRNA with high node centrality in the prediction network were validated by qPCR. CONCLUSIONS: Acupuncture significantly improves the neurological function and reduces the cerebral infarct area in CIRI rats, which may be related to the regulation of hippocampal circHDAC2/miR-3065/SLC30A3 axis.
