Small non-coding RNAs as regulators of structural evolution and carcinogenesis

Abstract

Small non-coding RNAs (sncRNAs) are part of non-coding oligonucleotide regulators with wide physiologic and morphologic functions. They control genetic programing of cells, and may modulate processes of differentiation and death. Biogenesis of sncRNAs is now known, and some sncRNAs have been proposed as markers of malignization. Epigenetic therapy is based on the use of newly discovered genetic modifiers, such as sncRNAs, micro-RNAs, and theirs mimics. However, role of sncRNAs in structural evolution and mechanisms of adaptation is not clearly understood. Certainly, non-coding RNAs participate in processes of cellular and organismal adaptation as well as cellular and tissue structural transformation as response to changing of environmental neighbouring. Investigations into these functions of sncRNAs may be the basis of future epigenetic environmental medicine.
