Differential MicroRibonucleic Acid Expression in Cardioembolic Stroke.

Background: MicroRNAs (miRNA) are a class of small, endogenous (17-25 nucleotide) noncoding ribonucleic acids implicated in the transcriptional and post-transcriptional regulation of gene expression. This study examines stroke-specific miRNA expression in large vessel territory cardioembolic stroke.

Methods: Peripheral blood was collected from controls and ischemic stroke patients 24 hours after stroke onset.
