Circulating microRNAs in Disease Diagnostics and their Potential Biological Relevance

MicroRNAs as the endogenous mediators of RNA interference have experienced an unprecedented career in recent years, highlighting their pathogenic, diagnostic and potential therapeutic relevance. Beside tissue microRNAs, they are also found in body fluids, most notably in blood. Significant differences of circulating microRNA levels have been found in various diseases, making them candidates for mi...
