Webb30 okt. 2024 · Introduction. Alternative splicing (AS) is the joining of different splice sites in a single primary transcript, thus creating multiple mature RNA isoforms and significantly expanding the protein repertoire of eukaryotic genomes (Graveley, 2001).There are four major classes of AS events: intron retention (IR), alternative 3′ splice sites (Alt3), … Webb15 juli 2024 · Although the functional mechanisms of many circRNAs have been revealed, how circRNAs are dysregulated in cancer remains elusive.
