Circrnas overview
WebJan 4, 2024 · Overview of circRNAs CircRNAs are created by a back-splicing process in which the downstream splice donor site is joined to the upstream splice acceptor site to form a covalently closed transcript. These molecules were first identified in a plant virus in 1976 ( Sanger et al., 1976 ) and identified as an endogenous RNA splicing product in ... WebApr 14, 2024 · Circular RNAs (circRNAs), which are produced post-splicing of pre-mRNAs, are strongly linked to the emergence of several tumor types. The initial stage in conducting follow-up studies involves identifying circRNAs. Currently, animals are the primary target of most established circRNA recognition technologies. However, the sequence features of …

WebCircRNAs are novel endogenous non-coding small RNAs involved in the regulation of multiple biological processes. However, little is known regarding circRNAs in ovarian development and maturation of fish. WebFeb 19, 2024 · CircRNA, a group of endogenous non-coding RNAs, has long been characterized as a single strand covalently closed continuous loop without 5′–3′ polarity and a polyadenylated tail ( Hansen et al., 2013 ).
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 ].
