The Molecular Revolution in Cutaneous Biology: Noncoding RNAs: New Molecular Players in Dermatology and Cutaneous Biology

Progress in genome sequencing achieved during the last two decades revealed that only about 2% of the genome codes for proteins, while the largest genome fraction is encoding thousands of non-coding RNAs. Non-coding RNAs play indispensable roles in regulating the activity and stability of the genome. Recent research in the area of the non-coding transcriptome signified the crucial roles for RNA regulatory networks in the normal development and their implications in a variety of pathological conditions. Here, recent advances in our understanding of non-coding RNA-mediated regulation of skin development and homeostasis are highlighted, focusing mainly on the regulatory roles of miRNAs and lncRNAs.
