Circulating Non-coding RNA in Acute Ischemic Stroke (AISRNA)

Noncoding RNAs have been highlighted to be involved in the pathological process of ischemic stroke (IS). The purpose of this protocol will investigate the expression pattern of circular RNA (circRNA), micro-RNA (miRNA) and long non-coding RNA (lncRNA) by next-generation sequencing in patients with acute ischemic stroke and healthy control. The candidate circRNA/miRNA/lncRNA will be verified as biomarkers for the detection and prognosis of acute ischemic 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 diagnostic or predictive model will be established using logistic regression. The panel of these altered ncRNAs may be associated with acute IS and could serve as a novel diagnostic or predictive method.
