Roles of Micro-RNAs in Metabolism

Research output: Chapter in Book/Report/Conference proceedingChapter


Micro-RNAs (miRNAs) are a group of small RNAs that inhibit gene expression by inducing mRNA degradation or repressing mRNA translation. miRNAs represent an ancient and evolutionally conserved mechanism to regulate gene expression in plants and animals. Growing evidence indicated that miRNAs participate in many metabolic processes, including adipocyte differentiation, development of pancreatic islet cells, insulin secretion and signaling, and fatty acid metabolism. Further, certain miRNAs are associated with metabolic dysregulation and thus are candidate targets for therapeutic development. Overall, the studies of miRNA have added a completely new dimension to our understanding of the complex regulatory mechanisms underlying energy homeostasis.
