Description
Cellular RNA molecules contain phosphate or hydroxyl ends. A 2′,3′-cyclic phosphate (cP) is one of the 3′-terminal forms of RNAs mainly generated from RNA cleavage by ribonucleases. Although transcriptome profiling using RNA-seq has become a ubiquitous tool in biomedical research, cP-containing RNAs (cP-RNAs) form a hidden layer of transcriptome, because standard RNA-seq is unable to capture them. Despite cP-RNAs’ invisibility in RNA-seq data, increasing evidence indicates that they are not accumulated simply as non-functional degradation products; rather, they have physiological roles in various biological processes, designating them as noteworthy functional molecules. We will present a comprehensive, genome-wide identification of short cP-RNA expression repertoire in cell lines and tissues, which has been achieved by our developed cP-RNA-seq. Our experimental data on the expressional regulation and functional roles of cP-RNAs in cancers, asthma, and infectious diseases will be further presented and discussed.
