Circulating Non-coding RNA in Acute Ischemic Stroke With Endovascular Treatment (EVTRNA)

Noncoding RNAs have been highlighted to be involved in the pathological process of ischemic stroke (IS). The purpose of this protocol will investigate the differentiated expression pattern of circular RNA (circRNA), long non-coding RNA (lncRNA) and micro-RNA (miRNA) by next-generation sequencing in acute ischemic stroke patients before and/or after endovascular treatment. The candidate circRNA/lncRNA/miRNA will be verified as the biomarker and regulator for progression and prognosis of acute ischemic stroke with endovascular treatment. Further, the candidate non-coding RNA will be used to evaluate the effect of endovascular treatment on both peripheral and central immune after stroke. Distinctive expression patterns of circRNA/miRNA/lncRNA will be identified by the next-generation sequencing and individual quantitative real time polymerase chain reaction (qRT-PCR). A predictive model will be established using logistic regression. The panel of these altered ncRNAs may be associated with the immune status after acute IS and could serve as a regulator for progression and prognosis of acute ischemic stroke with endovascular treatment.
