MicroRNAs and endocrine biology

microRNAs (miRNAs) are highly conserved, non-codnig RNAs that powerfully regulate gene expression at the post-transcriptional level. These fascinating molecules play essential roles in many biological processes in mammals, including insulin Secretion, B-cell development, and adipocyte differentiation. This review provides a general background regarding current knowledge about miRNA blogenesis and the potential contributions of these RNAs to endocrine function.
