Translational regulation by non-protein-coding RNAs: different targets, common themes.

摘要

There are several classes of small non-protein-coding RNA (npcRNA) that play important roles in cellular metabolism including mRNA decoding, RNA processing and mRNA stability. Indeed, altered expression of some of these npcRNAs has been associated with cancer, neurodegenerative diseases such as Alzheimer's disease, as well as various types of mental retardation and psychiatric disorders. The basis of this correlation is currently not understood. However, recent studies have begun to shed light on one of the mechanism(s) by which these RNAs exert their effects, namely, translational control. These data provide hope that rational treatments for these varied disorders may be in sight. Here, we review this new body of work.
