Abstract
MicroRNAs are small non-coding RNAs that can regulate gene expression by inhibiting translation or promoting mRNA degradation. miRNAs can be released into the circulation where they are carried by ribonucleoproteins, such as Agonaute-2, or lipoproteins, like HDL, or in extracellular vesicles or exosomes. Studies have shown an advantage of exosomes over artificial liposomes for RNA transpo…
