    About the Special Issue

    For many years, proteins were considered the main determining factors for the functioning of cells and organisms and their dysfunctions were assumed as the first cause of pathologies. This protein-centred view has been predominant in biology and biomedicine, but it was too simplistic to explain the complexity of the cell and the elusiveness of complex diseases. Today, it is well known that about 80% of our genome is dynamically and pervasively transcribed, mostly as non-protein-coding RNAs (ncRNAs). NcRNAs (e.g., miRNAs, lncRNAs, circRNAs) can bind DNA and proteins and interact with and regulate each other through various molecular mechanisms generating a complex network including different species of RNAs. Such a hidden network of RNA-RNA competitive interactions modulates the physiological functioning of canonical protein-coding pathways. NcRNAs constitute multiple control layers on classically known coding layers in cells by modulating chromatin architecture, gene transcription, RNA processing, stability and translation. Accordingly, their molecular dysregulations are strongly involved in the onset and progression of many pathologies, including cancers and degenerative diseases. The discovery of the critical role of ncRNAs in the cell’s physio-pathology shed new light on the understanding of molecular bases of complex diseases. Moreover, an impressive number of studies has shown that ncRNAs are secreted by cells into biological fluids (e.g., serum or plasma) as signals for the other cells through a hormone-like mechanism. The evidences that different pathological conditions specifically alter these RNA-based signals in extracellular environment pave the way to the exploitation of ncRNA dosage in biological fluids for diagnostic or prognostic purposes. 

    This Special Issue of Exploration of Medicine will encompass new research articles and reviews on the role of cellular and extracellular ncRNAs in physio-pathological conditions and their potential applications diagnostics and therapy.
