Circular RNAs as central regulators of RNA stability.
Circular RNAs (circRNAs) are a class of covalently closed, single-stranded RNAs generated predominantly through back-splicing of pre-mRNAs. Unlike their linear counterparts, circRNAs lack free 5' and 3' termini, rendering them intrinsically resistant to exoribonucleolytic degradation and conferring exceptional stabilit...
