WebSep 16, 2024 · Biogenesis of 620 circRNAs was linked to flanking CpG islands, whereas 457 circRNAs’ biogenesis mechanism appeared to relate to the flanking DNA self-chains. The amount of these seven clusters is summarized in Supplementary Figure S3 , while a complete list of the circRNAs is available in Supplementary Additional File S1 . WebSep 3, 2024 · Biogenesis of circRNAs. circRNAs are generated mainly from pre-mRNA through a phenomenon called backsplicing of exons. 25, 26 Most circRNAs contain complete exons and originate from protein-coding genes. Nevertheless, circRNAs might also consist of non-coding, antisense, intronic, 3′ untranslated region (UTR), 5′ UTR, or …
