Fig. 2From: Circular RNAs in organ injury: recent developmentSchematic illustration of the molecular mechanisms of circular RNAs. Circular RNAs have been suggested to participate in regulating biologically important pathways. It does so through a sponging miRNA to regulate RNA expression; b acting as protein decoys and scaffolds to facilitate protein–protein/protein-RNA interactions; c acting as regulatory elements for transcription and mRNA splicingBack to article page
