Extracellular miRNAs: From Biomarkers to Mediators of Physiology and Disease (Cell Metabolism)

In this Review, Mori et al. discuss the emerging literature of extracellular miRNAs as mediators of tissue crosstalk. They outline the ability of these miRNAs to act as effective biomarkers, as well as a new class of hormones, and thus their potential as monitors of and therapeutic agents for disease.
