AI Article Synopsis

  • Circular RNAs (CircRNAs) are a unique type of noncoding RNAs created through a process called backsplicing, found in many organisms and involved in various biological functions.
  • Although there has been significant research into how circRNAs are formed and their roles in diseases, there's limited understanding of how they are degraded, with only a few specific degradation pathways identified.
  • This overview aims to provide essential information about circRNAs and their degradation mechanisms, while also inspiring future research in this area for scholars interested in circRNA studies.

Article Abstract

Circular RNAs (CircRNAs) are a class of noncoding RNAs formed by backsplicing during cotranscriptional and posttranscriptional processes, and they widely exist in various organisms. CircRNAs have multiple biological functions and are associated with the occurrence and development of many diseases. While the biogenesis and biological function of circRNAs have been extensively studied, there are few studies on circRNA degradation and only a few pathways for specific circRNA degradation have been identified. Here we outline basic information about circRNAs, summarize the research on the circRNA degradation mechanisms and discusses where this field might head, hoping to provide some inspiration and guidance for scholars who aim to study the degradation of circRNAs.

Viroids are single-stranded circular noncoding RNAs that mainly infect crops. Upon infection, nuclear-replicating viroids engage host DNA-dependent RNA polymerase II for RNA-templated transcription, which is facilitated by a host protein TFIIIA-7ZF. The sense-strand and minus-strand RNA intermediates are differentially localised to the nucleolus and nucleoplasm regions, respectively.

Among women with cancer, breast cancer has surpassed lung cancer to become the most prevalent type of cancer globally. High-throughput sequencing of breast cancer tissues from many patients has revealed significant variations in circRNA expression across different types of breast cancer. Chemotherapy is currently a very important method for treating breast cancer; however, as the number of chemotherapy sessions increases and considering factors such as the patient's immune response, drug resistance has become a challenging issue in treating breast cancer.

Circular RNAs (circRNAs) are a unique class of covalently closed single-stranded RNA molecules that play diverse roles in normal physiology and pathology. Among the major types of circRNA, exon-intron circRNA (EIciRNA) distinguishes itself by its sequence composition and nuclear localization. Recent RNA-seq technologies and computational methods have facilitated the detection and characterization of EIciRNAs, with features like circRNA intron retention (CIR) and tissue-specificity being characterized.

Whole transcriptome and proteome analyses identify ncRNAs and mRNAs to predict competing endogenous RNA networks in hepatitis B virus-induced hepatocellular carcinoma.

The presence of the Hepatitis B virus (HBV) is considered as a valuable risk factor of hepatocellular carcinoma (HCC). To more deeply comprehend the molecular mechanism and transcriptome of HBV-induced HCC, we utilized tandem mass tagging (TMT)-based quantitative proteomics analysis and whole-transcriptome sequencing to analyze three sets of matched HepG2 hepatoma cells and HBV-positive HepAD38 cells. The differentially expressed (DE) proteins (1596), mRNAs (5263), miRNAs (581), lncRNAs (2672) and circRNAs (222) were subjected to differential expression and enrichment analyses in order to thoroughly assess the gene-regulatory circuits of HBV-induced HCC.

Purpose: Circular RNAs (circRNAs) are stable, non-coding RNAs with tissue- and developmental-specific expression making them suitable biomarkers for congenital anomalies. Current circRNA discovery pipelines have focused on human and mouse. We aim to bridge this gap by combining bioinformatics resources and used circtial1 as a model candidate in the nitrofen rat model of congenital diaphragmatic hernia (CDH).
