WebApr 13, 2024 · Recent studies have shown that circRNA molecules act as miRNA sponges in cells, thereby relieving the inhibition effect of miRNA on its target genes and increasing the expression level of target genes. This mechanism of action is called the competitive endogenous RNA (ceRNA) mechanism [ 10, 11, 12 ]. WebThe structure of circRNAs consists of a covalently closed loop formed by reverse splicing and the consequent removal of the 5ʹ cap and 3ʹ poly-A tail, making them resistant to exonuclease RNase R degradation and hence, relatively stable in the plasma. 9 CircRNAs are widely expressed in eukaryotic cells and exhibit cell- and tissue-specificity ...
