Advances of circRNA-miRNA-mRNA regulatory network in cerebral ischemia/reperfusion injury

Abstract

Ischemic stroke (IS) is the most common type of stroke, and its pathophysiological process is more complex. In recent years, the key regulatory roles of non-coding RNA (miRNA, circRNA) and mRNA in the development of IS have attracted more attention. In the process of cerebral ischemia/reperfusion injury, circRNA can regulate nerves, blood vessels and immune system through miRNA/mRNA axis, so as to affect the neurovascular unit of IS. The combination of these noncoding RNAs and mRNAs can be used as non-invasive biomarkers and therapeutic tools for IS diagnosis, prognosis and brain injury. Therefore, it is very important to study the potential molecular mechanism, activation pathway and treatment methods of circRNA/miRNA/mRNA network in IS. This review will focus on the latest progress of circRNA/miRNA/mRNA regulatory network, we have also included some circRNAs, which does not mediate through a miRNA, so we also include circRNA -mRNA network. And explore the application prospect of these RNAs as potential therapeutic targets in the prevention and treatment of IS.
