Abstract

Ischemic stroke predominates in all types of stroke and none neuroprotective agents success in the clinical trial. MicroRNAs are small endogenous noncoding RNA molecules that act as negative or positive regulators of gene expressions by binding completely or partially to complementary target sequences in the mRNAs. The genes which could be modulated by microRNAs play a role in the etiology and pathophysiology ischemic stroke. Therefore, microRNAs may have function on ischemic stroke. A lot of previous studies have investigated the roles of microRNAs in the ischemic stroke. This mini review would highlight the recent progress of microRNAs on the ischemic stroke. Accumulating evidence demonstrated that microRNAs contributed to the etiology of ischemic stroke and modulated the pathophysiological process such as brain edema, local inflammation, and apoptosis in the brain tissues after stroke. And we also discussed the potential application of microRNAs in ischemic stroke such as a biomarker of stroke and drug target. In conclusion, microRNAs play an important role in stroke etiology, pathophysiology, diagnosis, and therapy for ischemic stroke. It needs further research to investigate the biological function in ischemic stroke before it enters the clinical practice.
