報告摘要:
Long noncoding RNAs (lncRNAs) are emerging as new regulators in gene expression networks and exhibit a surprising range of shapes and sizes. Many lncRNAs are transcribed by RNA polymerase II and are capped, polyadenylated, and spliced like mRNAs. By developing methods for genome-wide discovery and characterization of non-polyadenylated RNAs, we have identified several RNA species with unexpected formats. These RNAs are derived from long primary transcripts via unusual RNA processing pathways and are stabilized by different mechanisms, including capping by small nucleolar RNA (snoRNA)–protein (snoRNP) complexes at their ends, and forming circular structures. We have shown that some such RNAs are involved in gene regulation through distinct mechanisms and are also implicated in human diseases. I will discuss our recent findings of underlying mechanisms related to their formation, subcellular localization and function.
