MicroRNA expression analysis of feline and canine parvovirus infection in vivo (felis).

ABSTRACT: Feline panleukopenia is a common contagious disease with high morbidity and mortality. At present, feline parvovirus (FPV) and canine parvovirus (CPV) variants are the pathogens of feline panleukopenia. Many studies have shown that miRNAs are involved in virus-host interactions. Nevertheless, miRNA expression profiling of FPV (original virus) or CPV-2b (new virus) in cats has not been reported. To investigate these profiles, three 10-week-old cats were orally inoculated with 106 TCID50 of the viruses (FPV and CPV-2b), and the jejunums of one cat in each group were sectioned for miRNA sequencing at 5 days post-inoculation (dpi). This study is the first attempt to use miRNA analysis to understand the molecular basis of FPV and CPV infection in cats. The miRNA expression profiles of the jejunums of cats infected with FPV and CPV were obtained, and a subset of miRNAs was validated by real-time qPCR. The results show that a variety of metabolism-related pathways, cytokine- and pathogen-host interaction-related pathways, and pathology- and cellar structure-related pathways, as well as others, were affected. Specifically, the JAK-STAT signaling pathway, which is critical for cytokines and growth factors, was enriched. This description of the miRNAs involved in regulating FPV and CPV infection in vivo provides further insight into the mechanisms of viral infection and adaptation and might provide an alternative antiviral strategy for disease control and prevention.

Project description:BackgroundMicroRNAs (miRNAs) play an essential role in gene regulators in many biological and molecular phenomena. Unraveling the involvement of miRNA as a key cellular factor during in vitro canine parvovirus (CPV) infection may facilitate the discovery of potential intervention candidates. However, the examination of miRNA expression profiles in CPV in tissue culture systems has not been fully elucidated.MethodIn the present study, we utilized high-throughput small RNA-seq (sRNA-seq) technology to investigate the altered miRNA profiling in miRNA libraries from uninfected (Control) and CPV-2c infected Crandell Reese Feline Kidney cells.ResultsWe identified five of known miRNAs (miR-222-5p, miR-365-2-5p, miR-1247-3p, miR-322-5p and miR-361-3p) and three novel miRNAs (Novel 137, Novel 141 and Novel 102) by sRNA-seq with differentially expressed genes in the miRNA repertoire of CPV-infected cells over control. We further predicted the potential target genes of the aforementioned miRNAs using sequence homology algorithms. Notably, the targets of miR-1247-3p exhibited a potential function associated with cellular defense and humoral response to CPV. To extend the probing scheme for gene targets of miR-1247-3p, we explored and performed Gene Ontology (GO) enrichment analysis of its target genes. We discovered 229 putative targets from a total of 38 enriched GO terms. The top over-represented GO enrichment in biological process were lymphocyte activation and differentiation, marginal zone B cell differentiation, negative regulation of cytokine production, negative regulation of programed cell death, and negative regulation of signaling. We next constructed a GO biological process network composed of 28 target genes of miR-1247-3p, of which, some genes, namely BCL6, DLL1, GATA3, IL6, LEF1, LFNG and WNT1 were among the genes with obviously intersected in multiple GO terms.ConclusionThe miRNA-1247-3p and its cognate target genes suggested their great potential as novel therapeutic targets or diagnostic biomarkers of CPV or other related viruses.
