BK virus infection induces changes of cellular gene expression in Vero cell

ABSTRACT: The general aim of this paper is to explore a little further into molecular biology of the interaction between virus and host cell. We seek to use cDNA microarray technology, one revolutionary methodological advance, to perform a high throughput analysis of cDNA clones with the intent of identifying genes expressed in association with the infection with BKV in Vero cells (green monkey kidney cells). This technology, which can supply quantitative expression information for many thousands of genes simultaneously, has been used to classify the cellular genes at transcript levels in different physiological states of a tissue or cell. Accordingly, in this study, we have constructed a cDNA microarray containing 32448 spots (quadruplication of 7,334 human cDNAs and doping controls) to study that BKV infection of Vero cells. Our purposes were (i) to appraise whether cDNA microarrays could be employed to investigate the expression of cellular genes during the 5 time courses (5, 10, 15, 19 and 25 days post-infection (dpi)) of infection with BKV, (ii) to identify any genes that resulted in up-regulation or down-regulation of cell gene expression transcription, (iii) to determine the etiological role of BKV in nephropathy and/or neoplasia, (iv) to form a clearer picture of virus-associated pathophysiology in kidney.

Transcription profiling by array of Vero cells infected by different Chikungunya virus strains to identify common human host genes involved in pathogenesis of different Chikungunya viruses

Project description:In this study, we aim to identify common host genes involved in pathogenesis of different Chikungunya virus strains as an attempt to recognize probable antiviral targets. We have compared the host gene regulation after infection of monkey kidney cell line (Vero) with two different wild type CHIKV strains i.e. S 27 (human, ECSA), and DRDE-06 (human, ECSA). Vero cells were mock infected or infected with two Chikungunya virus strains (S 27 and DRDE-06) and harvested at 8hpi and 18hpi. The total RNA was extracted and microarray was done using Agilent protocol.

Large scale gene expression of Vero cell correlated to infection of infectious bursal disease virus

Project description:Infectious bursal disease virus (IBDV) is the pathogenic agent of infectious bursal disease (IBD). Scine it was observed in 1957, IBD spread worldwidely in the chicken flocks, is a important immunosuppressive disease and an threat to poultry industry. Although many studies have be done about IBDV, interaction of IBDV infection and IBDV-encoding genes to host cell gene expression are little known. In this study, the LongSAGE library of Vero-cell, IBDV- infected vero cell, Vero-cell transfected with IBDV-VP5 gene, Vero-cell transfected with IBDV A frament and Vero-cell transfected with IBDV VP243 frament were obtained. We got 96,213 gene tags (17 nucleotides), which represented 24,475 transcripts. Keywords: Transcripts of different state vero-cell 1.Cloning of the full-length genomic A-segment, VP5 ORF cDNA, VP243 ORF cDNA of IBDV 2.Establishing cloned Vero cell lines expressing VP5, VP243 and A fragment of IBDV 3.Construction of Long-SAGE libraries 4.

Transcriptomic analysis of the Novel Middle East Respiratory Syndrome Coronavirus (African green monkey, Vero E6 cells)

Project description:We will use the EMC/2012 strain of the novel beta Coronavirus called Middle East Respiratory Syndrome Coronavirus (MERS-CoV). It was initially passaged on Vero E6 cells in Saudi Arabia before being sequenced at the Erasmus Medical College in Rotterdam, Netherlands by Dr Ron Fouchier. We propose to perform a time course of infection of hCoV-EMC on MRC5 cells (Human Lung origin) and Vero cells (African Green Monkey Kidney cells). Both cell lines readily grow and replicate the virus. Importantly these cell lines show signs of Cytopathic effect (CPE), such as cell rounding and release from the petri dish that coincide with time points high virus replication demonstrating the effects of virus replication on the cells. Transcriptomic analysis will be performed after infection with MERS-CoV and SARS-CoV (Urbani strain) to compare the host gene induction that occurs during infection. MRC5 and Vero E6 cells will be infected at an MOI of 0.1 and 3 and RNA harvested from cells at 24 and 48 post infection. RNA will be processed for library creation and sequenced on an Illumina Hiseq. Sequencing reads will be analyzed and compared across the time course and between each virus to identify common response pathways induced during infection as well as unique pathways specific to each virus.

Genome-wide analysis of simian virus 40 infected cells

Project description:The goal of this study was to compare the whole transcriptional profile (RNA-seq) of simian virus 40 infection and mock infected Vero cells at 72 hours post infection. Circular RNAs (circRNAs), identified as a class of widely expressed endogenous regulatory RNAs, are involved in diverse physiological and pathological processes. However, their role in viral pathogenesis and cellular antiviral response remains unexplored. In this study, a potent DNA tumor virus, simian virus 40 (SV40), was used as a model to investigate the viral influences on cellular circRNA transcriptome. Using RNA-seq, 15,241 putative circRNAs were identified de novo from 5,057 parental genes in monkey kidney–derived Vero cells. The expression of selected circRNAs was confirmed by reverse transcription-polymerase chain reaction and Sanger sequencing. Further analysis showed that most circRNAs comprised multiple exons, and most parental genes produced multiple circRNA isoforms. A total of 134 significantly dysregulated circRNAs, including 103 upregulated and 31 downregulated circRNAs, were found after SV40 infection. Gene ontology and Kyoto Encyclopedia of Genes and Genomes pathway analysis revealed that various cancer-related pathways, including p53 and Wnt pathway, could be affected by SV40 infection via the alteration of the circRNA hosting genes. Moreover, diverse cellular immune pathways, including Toll-like receptor pathway and Janus kinase–signal transducer and activator of transcription pathway, could also be affected by SV40 infection. An integrated circRNA-miRNA-gene analysis suggested the putative function of circRNAs as cellular and viral miRNA decoys to indirectly regulate the gene expression during SV40 infection. This study presented the first comprehensive expression and functional profile of circRNAs in response to SV40 infection, thus providing new insights into the mechanisms of viral pathogenesis and cellular immune response.
