MicroRNA-126 Regulates Thrombosis Through Endothelial Progenitor Cells

Abstract

Thrombosis is a common problem with potentially severe consequences. Endothelial progenitor cells (EPCs) show great potential as a thrombosis therapy due to their angiogenesis-promoting, thrombus-relieving, and anticoagulant functions. However, cell therapies present more clinical challenges than small molecule solutions. MicroRNAs (miRNAs) are small noncoding single-stranded RNAs with wide-ranging regulatory activities. miRNA-126 is highly enriched in EPCs and endothelial cells. Although increasing research showed that mircoRNA-126 (miR-126) can regulate EPC functions through various pathways and cytokines, summaries of these interactions are rare. Therefore, this brief review of recent findings on the relationship between miRNA-126 and EPC function will attempt to clarify the role of miR-126 in thrombosis through regulation of EPCs, with the goal of exploring alternative therapies for thrombotic diseases.
