(Submitter supplied) Epstein-Barr virus (EBV)-transformed lymphoblastoid cell lines (LCLs) provide a conveniently accessible and renewable resource for functional studies in humans. The ability to accumulate multidimensional data pertaining to the same individual cell lines, from complete genomic sequences to detailed gene regulatory profiles, further enhances the utility of LCLs as a model system. A lingering concern, however, is that the changes associated with EBV transformation of LCLs reduce the usefulness of LCLs as a surrogate model for primary tissues. more...

(Submitter supplied) Epstein-Barr virus (EBV) transformed lymphoblastoid cell lines (LCLs) are a widely used renewable resource for functional genomic studies in humans. The ability to accumulate multidimensional data pertaining to the same individual cell lines, from complete genomic sequences to detailed gene regulatory profiles, further enhances the utility of LCLs as a model system. However, the extent to which LCLs are a faithful model system is relatively unknown. more...

(Submitter supplied) Statin-induced gene expression differences observed in LCLs may be influenced by their transformation, and thus differ from those observed in native B-cells. To assess this possibility, we prepared LCLs and purified B-cells from the same donors, and compared mRNA profiles after 24hr incubation with simvastatin (2µM) or sham buffer.

(Submitter supplied) EBNA1 is the EBV-encoded nuclear antigen required for viral episome maintenance during latency. EBNA1 is a sequence specific DNA binding protein with high affinity binding sites for the viral genome, especially OriP. EBNA1 can also bind sequence specifically to a large number of sites in the host cellular genome, but the function of these binding sites has remained elusive. EBNA1 is also known to provide a host cell survival function, but the molecular mechanisms accounting for this function are not completely understood. more...

(Submitter supplied) Genome wide association studies have identified >200 susceptibility loci accounting for much of the heritability of Multiple Sclerosis (MS). Epstein-Barr virus (EBV), a memory B cell tropic virus, has been identified as necessary but not sufficient for development of MS. The molecular and immunological basis for this has not been established. Infected B cell proliferation is driven by signalling through the EBV produced cell surface protein LMP1, a homologue of the MS risk gene CD40. more...

(Submitter supplied) The genome of Epstein-Barr virus (EBV) encodes 86 proteins but only a limited set is expressed in EBV-growth transformed B cells, termed lymphoblastoid cell lines (LCLs). These cells proliferate via the concerted action of EBV nuclear antigens (EBNAs) and latent membrane proteins (LMPs), some of which are rate limiting to establish a stable homeostasis of growth promoting and anti-apoptotic activities. more...

(Submitter supplied) Super-enhancers are principal determinants of cell transcription, development, phenotype, and oncogenesis, not yet implicated in host-pathogen interactions. We found four Epstein-Barr virus (EBV) oncoproteins and five EBV-activated NF-B subunits co-occupying thousand of enhancer sites in EBV-transformed lymphoblastoid cells (LCLs). Of these, 187 had markedly higher and broader histone H3K27ac signals characteristic of super-enhancer formation, and were designated “EBV super-enhancers”. more...

(Submitter supplied) To identify gene expression changes and pathways induced by interferon-β (IFN-β) in B cells, we studied the in vitro response of EBV-transformed B cells (lymphoblast cell lines-LCLs). LCLs were derived from an MS patient repository. Whole genome expression analysis identified 115 genes that were more than two-fold differentially up-regulated following IFN-β exposure, with over 50 novel IFN-β response genes. more...

(Submitter supplied) Genome wide DNA methylation profiles of B cell and B cells infected with EBV (LCLs). The Illumina Infinium 27k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 27,000 CpGs in B cells and EBV infected B cells. Samples included 8 normal B cells without EBV, 8 normal B cells with EBV.

(Submitter supplied) We investigated the effects of experimental EBV infection of B cells on DNA methylation profiles by using high-throughput analysis. Remarkably, we observed hypomethylation of around 250 genes, but no hypermethylation. Hypomethylation did not occur at repetitive sequences, consistent with the absence of genomic instability in lymphoproliferative cells. Changes in methylation only occurred after cell divisions started, without the participation of the active demethylation machinery, and were concomitant with acquisition of B cells of the ability to proliferate. more...

(Submitter supplied) We report single-cell RNA sequencing datasets for three lymphoblastoid cell lines (LCLs) prepared by infection of primary B cells with Epstein-Barr Virus (EBV). Inter- and intra-sample transcriptional variance is observed with respect to immunoglobulin heavy chain class; host gene sets involved in survival, proliferation and differentiation; and viral replication state. We propose that the observed heterogeneity arises from the dynamic nature of host-pathogen interactions, donor-specific compositions of primary B cells, and other experimental factors such as stochastic clonal evolution in cell culture conditions.

(Submitter supplied) DNA from Epstein-Barr virus (EBV)-transformed lymphocyte cell lines (LCLs) has proven very useful for studies of genetic sequence polymorphisms. Whether EBV-LCL DNA is suitable for methylation studies is less clear. We conduct a genome-wide methylation investigation using an array set with 45 million probes to investigate the methylome of EBV-LCL DNA and technical duplicates of whole blood (WB) DNA from the same 10 individuals. more...

(Submitter supplied) Readily accessible samples such as peripheral blood or cell lines are increasingly being used in large cohorts to characterise gene expression differences between a patient group and healthy controls. However, cell and RNA isolation procedures and the variety of cell types that make up whole blood can affect gene expression measurements. We therefore systematically investigated global gene expression profiles in peripheral blood from six individuals collected during two visits by comparing five of the following cell and RNA isolation methods: whole blood (PAXgene), peripheral blood mononuclear cells (PBMCs), lymphoblastoid cell lines (LCLs), CD19 and CD20 specific B-cell subsets. more...
