Circrna back-splicing
WebJul 15, 2024 · (A) Canonical splicing occurs first, exon skipping forms an mRNA composed of exons 1 and 4, and a lariat structure composed of exons 2 and 3, and then back … WebCircular RNAs (circRNAs) are a recently discovered class of RNAs derived from protein-coding genes that have important biological and pathological roles. They are formed through backsplicing during co-transcriptional alternative splicing; however, the unified mechanism that accounts for backsplicing decisions remains unclear.

WebAug 30, 2024 · Studies have revealed that circRNAs are mainly derived from pre-mRNAs and that the mechanism underlying circRNA formation differs from the standard splicing mechanism used to produce linear RNA [ 19 ]. CircRNAs are derived from a noncanonical form of alternative splicing called back-splicing [ 5, 12 ]. WebJan 24, 2024 · Circular RNAs (circRNAs) are covalently closed RNAs derived from back-splicing of genes across eukaryotes. Through alternative back-splicing (ABS), a single …
WebThis splicing method is called back-splicing. 12, 17 The splicing regulatory mechanisms of circRNAs biogenesis are different from the linear isoforms. CircRNAs demonstrate significant and diverse back-splicing events catalyzed by typical spliceosome mechanisms in different cell lines. 13, 18–20 CircRNAs are pervasive in molecular biology. WebJul 15, 2024 · CircRNAs are generated by a “back-splicing” process, which is regulated by different cis-regulatory elements and trans-acting proteins. Therefore, how these cis and trans elements change during tumorigenesis and how they regulate the biogenesis of circRNAs in cancer are two questions that interest us.
