“…Although the functions of circRNAs are yet largely unclear, accumulating evidence indicates their involvement in modulating the disease progression [41][42][43][44]. Thus, it is vital to understand the biological functions of circRNAs by investigating their expression patterns and interactions with other types of RNAs.…”

Background/Aims: Circular RNAs (circRNAs), a new class of regulators of gene expression, are involved in diverse physiological and pathogenic processes. However, their role in cellular responses to virus infection is yet unclear. Methods: A human lung fibroblast cell line was infected or mock infected by herpes simplex virus 1 (HSV-1). Deep RNA sequencing was used to profile the global changes in circRNAs, genes, and miRNAs following HSV-1 infection. Altered circRNAs, genes, and miRNAs were validated using quantitative reverse transcription polymerase chain reaction (RT-qPCR). An integration analysis of circRNAs, genes, and miRNAs was applied to investigate the putative function of the dysregulated circRNAs. Results: A total of 536 circRNAs, 3,885 genes, and 207 miRNAs were significantly dysregulated after HSV-1 infection. An integration analysis of circRNAs, genes, and miRNAs revealed the alleged involvement of dysregulated circRNAs in cellular responses to HSV-1 infection via the circRNA-miRNA-gene regulatory axis. These genes regulated by circRNAs were enriched to NOD-like receptor/JAK-STAT signaling pathway, and pathways of apoptosis, cell cycle progression, and cell death, all of which may be implicated in the viral pathogenesis and cellular immunity. Conclusions: These data present a comprehensive view for circRNAs induced by HSV-1 and their interplay with miRNAs and genes during HSV-1 infection, thus offering new insights into the mechanisms of interactions between HSV-1 and the host.

“…To date, several studies have proved that circRNAs may regulate gene expression by manipulating miRNAs through its miRNA sponges function [36], and circRNAs also compete with mRNAs for miRNA binding in the cytoplasm and interfere in gene regulation [8]. MiRNAs control a large set of biological processes through direct interaction with their target mRNA, so circRNA sponge activity will also affect these pathways [37,38].…”

ALV-J (subgroup J avian leucosis virus) is a kind of oncogenic exogenousretrovirus and diseases associated with ALV-J have caused severe reproduction problems in the poultry industry worldwide. However, the pathogenesis of ALV-Jinduced tumor formation is still unclear. In recent years, circRNAs are validated to be related to cancer, which prompts us to explore whether aberrant expression of circRNAs exists in ALV-J-infected tumor samples. In this study, a total of 2822 differentially expressed circRNAs were detected by RNA sequencing in the tumor livers of ALV-J-susceptible chickens (n = 3) and the normal liver samples of ALV-J-resistant chickens (n = 3), among which 2808 circRNAs in the tumor liver samples were detected as unregulated compared to those in the normal liver samples. As circRNAs are considered as miRNA sponge, we predicted top 5 miRNA targets for 24 selected upregulated circRNAs in the ALV-J-induced tumor livers. CircRNA-miRNA-mRNA regulatory axes were also constructed to provide clear interaction relationship among them. Furthermore, Gene Ontology and KEGG pathway analyses were performed for miRNA target genes, the result of which implied that metabolism plays a key role in circRNAs alterations in ALV-J-induced tumor livers. In summary, we identified that circRNAs are involved in ALV-J-induced tumor formation in chickens. However, the pathogenicity mechanism still needs to be further explored.

Circular RNA from backspliced exons (or exonic circular RNA, circRNA) is a type of covalently closed noncolinear RNA that was recently rediscovered in eukaryotes. Although circRNAs are often expressed at low levels, emerging evidence indicates that many circRNAs are linked to physiological development and various diseases. Notably, circRNAs have been shown to serve as oncogenic stimuli or tumor suppressors in cancer. circRNAs may regulate gene expression through different mechanisms. In addition, circRNAs have been shown to be useful as biomarkers of diseases due to their stability, specific expression and relation to diseases both in cells and in extracellular fluid. This review summarizes current knowledge of human circRNAs and discusses the emerging role and clinical implication of these multifarious transcripts.
