Project description:RNA-sequencing data of mock, wild-type, and EndoUmut MHV A59 infected IFNAR-/- bone-marrow derived macrophages. RNA was isolated at 6 hours post infection and immunoprecipitated with anti-dsRNA antibody to determine which RNA are forming a dsRNA epitope during viral infection. RNAs were mapped to C57Bl/6 Mouse genome or MHV-A59 genome (Genbank accession # AY910861).

Project description:The mouse hepatitis virus (MHV) genomic and sub-genomic RNAs have 3’ poly(A) tails. The terminal addition of uridines to poly(A) tails has been shown to be a widespread modification. Here, we investigated the presence of 3' end additions on the MHV RNA poly(A) tails. To this end, we infected NCTC cells with MHV and isolated RNA at 24-hours post-infection (hpi). While the median poly(A) tail length of the MHV RNAs is around 50 nucleotides, we observed a peak of uridylation in transcripts with poly(A) tails about 40 nucleotides long

Project description:The mouse hepatitis virus (MHV) genomic and sub-genomic RNAs are 3’ polyadenylated. The length of the 3’ poly(A) tail is known to change during infection, but little is known about the molecular mechanisms driving this change. Here, we investigate the presence of terminal uridylation and terminal guanylation on the MHV poly(A) tail during infection. We infected 17-CL1 cells with MHV and isolated RNA at 24- and 48-hour post-infection (hpi). We observed that MHV RNAs poly(A) tails shortened during infection and that short poly(A) tails of about 20 nucleotides are highly uridylated.

Project description:Murine gammaherpesvirus 68 (MHV-68) is closely related to Epstein-Barr virus (EBV) and KaposiM-bM-^@M-^Ys sarcoma-associated herpesvirus (KSHV) and provides a small animal model to study the pathogenesis of gammaherpesvirus (M-NM-3HV) infections. To completely explore the potential of the MHV-68 system for the investigation of gHV miRNAs, it would be desirable to know the number and expression patterns of all miRNAs encoded by MHV-68. By using small RNA deep sequencing, we systematically investigated the MHV-68 miRNA expression profiles in both lytically and persistently infected cells. In addition to the known nine MHV-68 miRNAs, we identified six novel MHV-68 miRNA genes and analyzed the expression levels of all MHV-68 miRNAs. Furthermore, we also characterized the cellular miRNA expression signatures in MHV-68 infected versus non-infected NIH3T3 fibroblasts and in TPA-treated versus non-treated S11 cells. We found that mmu-mir-15b and mmu-mir-16 are highly upregulated upon MHV-68 infection of NIH3T3 cells, indicating a potential role of cellular miRNAs during MHV-68 infection. Our data will aid to fully explore the functions of gHV miRNAs. A mouse fibroblast cell line infected with/without MHV-68 and a MHV-68 infected mouse B lymphoma cell line treated with/without TPA (4 samples in total) were examined.

Project description:Murine gammaherpesvirus 68 (MHV-68) is closely related to Epstein-Barr virus (EBV) and Kaposi’s sarcoma-associated herpesvirus (KSHV) and provides a small animal model to study the pathogenesis of gammaherpesvirus (γHV) infections. To completely explore the potential of the MHV-68 system for the investigation of gHV miRNAs, it would be desirable to know the number and expression patterns of all miRNAs encoded by MHV-68. By using small RNA deep sequencing, we systematically investigated the MHV-68 miRNA expression profiles in both lytically and persistently infected cells.

Project description:The severity and outcome of respiratory viral infections is partially determined by the cellular response mounted by infected lung epithelial cells. Disease prevention and treatment is dependent on our understanding of the shared and unique responses elicited by diverse viruses. We used microarray analysis to compare changes in gene expression of murine lung epithelial cells infected by one of three respiratory viruses causing mild (rhinovirus, RV1B), moderate (coronavirus, MHV-1), and severe (influenza A virus, PR8) disease in mice. The viruses prompted changes in host gene expression that differed in magnitude and timing. RV1B infection caused numerous gene expression changes, but the differential effect peaked at 12 hours post-infection. PR8 altered an intermediate number of genes whose expression continued to changes through 24 hours. MHV-1 had comparatively few effects on host gene expression. All three viruses elicited overlapping responses in antiviral defense systems, though MHV-1 induced a lower type I IFN response than the other two viruses. Our comparative approach identified signatures of each virus infection that can be used to discover mechanisms of pathogenesis in the respiratory tract.
