N6-methyladenosine RNA methylation modification regulates the transcription of viral-derived E (XSR) miRNAs to promote ALV-J replication
The E (XSR) element located in the 3′UTR of the ALV-J genome has the capability to transcribe and generate viral-derived E (XSR) miRNA. However, the biological function and transcriptional regulation mechanism of this process remain unclear. In this study, the impact of E (XSR) miRNA on ALV-J replication and the regulatory effect of N6-methyladenosine (m6A) methylation on its transcription were investigated. The results demonstrated that E (XSR) miRNA could stimulate ALV-J replication and suppress apoptosis in DF-1 cells in vitro. E (XSR) miRNA's promotion of ALV-J replication was not associated with the type I interferon pathway, but achieved by suppressing the expression of the host GPC5 gene. The transcription of E (XSR) miRNA could be promoted by m6A methylation modification, where m6A modification was found at the A6880 and A7016 sites of ALV-J gRNA. This study provides a new perspective on the transcription of ALV-J E (XSR) miRNA and its regulatory function in ALV-J replication.
期刊介绍：
Veterinary Microbiology is concerned with microbial (bacterial, fungal, viral) diseases of domesticated vertebrate animals (livestock, companion animals, fur-bearing animals, game, poultry, fish) that supply food, other useful products or companionship. In addition, Microbial diseases of wild animals living in captivity, or as members of the feral fauna will also be considered if the infections are of interest because of their interrelation with humans (zoonoses) and/or domestic animals. Studies of antimicrobial resistance are also included, provided that the results represent a substantial advance in knowledge. Authors are strongly encouraged to read - prior to submission - the Editorials (''Scope or cope'' and ''Scope or cope II'') published previously in the journal. The Editors reserve the right to suggest submission to another journal for those papers which they feel would be more appropriate for consideration by that journal.
Original research papers of high quality and novelty on aspects of control, host response, molecular biology, pathogenesis, prevention, and treatment of microbial diseases of animals are published. Papers dealing primarily with immunology, epidemiology, molecular biology and antiviral or microbial agents will only be considered if they demonstrate a clear impact on a disease. Papers focusing solely on diagnostic techniques (such as another PCR protocol or ELISA) will not be published - focus should be on a microorganism and not on a particular technique. Papers only reporting microbial sequences, transcriptomics data, or proteomics data will not be considered unless the results represent a substantial advance in knowledge.
Drug trial papers will be considered if they have general application or significance. Papers on the identification of microorganisms will also be considered, but detailed taxonomic studies do not fall within the scope of the journal. Case reports will not be published, unless they have general application or contain novel aspects. Papers of geographically limited interest, which repeat what had been established elsewhere will not be considered. The readership of the journal is global.
