(Submitter supplied) Epstein-Barr virus (EBV) epigenetically reprogrammes B-lymphocytes to drive immortalization and facilitate viral persistence. Host-cell transcription is perturbed principally through the actions of EBV EBNA 2, 3A, 3B and 3C, with cellular genes deregulated by specific combinations of these EBNAs through unknown mechanisms. Comparing human genome binding by these viral transcription factors we discovered that 25% of binding sites were shared by EBNA 2 and the EBNA 3s and were located predominantly in enhancers. more...

(Submitter supplied) We undertook ChIP-Seq of HA-tagged EBNA3A in Lymphoblastoid Cell Lines to understand the effects of this essential viral transcription factor on the cell DNA. We discovered that EBNA3A bound to DNA with BATF, IRF4 and RUNX3, making these Transcription Factors the ones that tether EBNA3A to DNA, allowing it to mediate its downstream effects.

(Submitter supplied) Epstein-Barr Virus (EBV) immortalizes resting B-lymphocytes through a highly orchestrated process involving extensive reprogramming of host transcription and metabolism. Here, we use multiple omics-based approaches concurrently across the time course of B-cell infection to investigate the underlying mechanisms that control EBV-induced B-cell immortalization. ATAC-seq revealed that over a third of accessible chromatin is altered with the most perturbed sites overlapping Ets-family, including PU.1 and RUNX1 transcription factors. more...

(Submitter supplied) Epstein-Barr Virus Nuclear Antigen 2 (EBNA2) gene regulation through the cell RBPJ transcription factor (TF) is essential for conversion of resting B-lymphocytes (RBLs) into Lymphoblastoid Cell Lines (LCLs). ChIP-seq investigation of EBNA2 and RBPJ sites in LCL DNA found EBNA2 at 5151 and RBPJ at 10,529 sites. EBNA2 was 72% localized with RBPJ, predominantly at intergenic and intronic sites and only 14% at promoter sites. more...

(Submitter supplied) We analysed epigenetic alterations by EBV infection especially at enhancer regions, to elucidate their contribution to tumorigenesis. We performed ChIP-seq on H3K4me3, H3K4me1, H3K27ac, H3K27me3 and H3K9me3 using gastric epithelial cells with or without EBV infection. We showed that repressive marks were redistributed after EBV infection, resulting in aberrant enhancer activation and repression. Enhancer dysfunction leads to activation of pathway related to cancer hallmarks (e.g. 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) Epstein-Barr virus (EBV) episome is known to interact with the three-dimensional structure of human genome in infected cells. However, the exact locations of these interactions and their potential functional consequences remain unclear. Recently the high-resolution chromatin interaction capture (Hi-C) assays in lymphoblastoid cells have become available enabling us to precisely map the contacts between the EBV episome(s) and the human host genome. more...

(Submitter supplied) Two cell lines, BL41K3 and BJABK3, were chosen to perform a comprehensive screen for EBNA-2 target genes. Both cell lines are EBV negative B-cell lines and express a chimeric EBNA-2 protein fused to the hormone binding domain of the estrogen receptor (ER/EBNA-2). The cells are propagated in the absence of hormone 31,36. Estrogen stimulation activates ER/EBNA-2, which in turn activates well known EBNA-2 target genes like CD21. more...

(Submitter supplied) There are two major types of Epstein-Barr Virus (EBV): type 1 (EBV-1) and type 2 (EBV-2). EBV functions by manipulating gene expression in host B cells, using virus-encoded gene regulatory proteins including Epstein Barr Nuclear Antigen 2 (EBNA2). While type 1 EBNA2 is known to interact with human transcription factors (hTFs) like RBPJ, EBF1, and SPI1, type 2 EBNA2 shares only ~50% amino acid identity and may have distinct effects on the genome. more...

(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...

EBV regulome contained 1992 genes and enhancers directly linked to them. ~30% of genes essential for LCL growth were linked to EBV enhancers. more...
