Exploring Noninvasive Biomarkers with the miRandola Database: A Tool for Translational Medicine.

Noninvasive biomarkers are required for addressing crucial clinical needs. The ideal biomarker should be easily accessible and provide a unique characteristic for a healthy status or a pathological condition. In the last years, microRNAs (miRNAs) have been proposed as promising tissue-based biomarkers for several diseases such as cancer and cardiovascular diseases. Recently, miRNAs have shown great potential as novel noninvasive biomarkers, due to their high stability in human body fluids such as serum, plasma, and urine. Furthermore, many other noncoding RNAs (ncRNAs) such as long noncoding RNAs (lncRNAs) and circular RNAs (circRNAs) have shown to be novel biomarkers as well. The aim of this exciting research field is to offer novel tools, allowing translational scientists to develop new strategies for diagnosis, screening, and monitoring of diseases. In this book chapter, the miRandola database and its applications will be introduced. The database offers the possibility to explore information on ncRNAs as noninvasive biomarkers, manually extracted from scientific literature and public available resources.
