Abstract
MicroRNAs (miRNAs) are small molecules of non-coding RNAs whose primary function is the modulation of gene expression through the interaction with target messenger RNA (s). MiRNAs can be released into extracellular fluids and transported in different ways, namely I) internalized in extracellular vesicles, such as exosomes and microvesicles; II) vesicles free miRNA, bound to the Ago2 prote…
