Advances in Circular RNA and Its Applications
International Journal of Medical Sciences, 2022 Circular RNA (circRNA) is a novel endogenous non-coding RNA (ncRNA) that, like microRNA (miRNA), is a rapidly emerging RNA research topic. CircRNA, unlike traditional linear RNAs (which have 5' and 3' ends), has a closed-loop structure that is unaffected

The Biogenesis of Nascent Circular RNAs [PDF]
Cell Reports, 2016 Steady-state circular RNAs (circRNAs) have been mapped to thousands of genomic loci in mammals. We studied circRNA processing using metabolic tagging of nascent RNAs with 4-thiouridine (4sU). Strikingly, the efficiency of circRNA processing from pre-mRNA is extremely low endogenously.

Circular RNAs and esophageal cancer [PDF]
Cancer Cell International, 2020 AbstractAs a new kind of RNA, circular RNA (circRNA) is a endogenous non-coding RNA with circular structure, which has the characteristics of universality, stability, conservatism and specificity. CircRNA can specifically bind to microRNAs (miRNAs) in the form of competitive endogenous RNA, thus directly or indirectly regulating the expression of ...

circBase: a database for circular RNAs [PDF]
RNA, 2014 Recently, several laboratories have reported thousands of circular RNAs (circRNAs) in animals. Numerous circRNAs are highly stable and have specific spatiotemporal expression patterns. Even though a function for circRNAs is unknown, these features make circRNAs an interesting class of RNAs as possible biomarkers and for further research. We developed a

Hepatology, 2017 Noncoding RNAs play important roles in cancer biology, providing potential targets for cancer intervention. As a new class of endogenous noncoding RNAs, circular RNAs (circRNAs) have been recently identified in cell development and function, and certain ...

Circular RNA is expressed across the eukaryotic tree of life. [PDF]
PLoS ONE, 2014 An unexpectedly large fraction of genes in metazoans (human, mouse, zebrafish, worm, fruit fly) express high levels of circularized RNAs containing canonical exons.

Nucleic Acids ResearchCircular RNAs (circRNAs) are covalently closed RNAs that are present in all eukaryotes tested. CircRNAs are less abundantly expressed than mRNAs. Recent RNAseq analyses indicate that more than 800,000 circRNA isoforms exist in humans, which is more than twice the number of currently known mRNA isoforms. CircRNAs are generated through backsplicing that

Molecular mechanisms of circular RNA translation
Experimental and Molecular MedicineCircular RNAs (circRNAs) are covalently closed single-stranded RNAs without a 5′ cap structure and a 3′ poly(A) tail typically present in linear mRNAs of eukaryotic cells.

A stepwise emergence of evolution in the RNA world
FEBS Letters, EarlyView.How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to
