(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) Epstein-Barr Virus (EBV) encoded Nuclear Antigens (EBNAs) and virus activated NF-kB subunits mostly bind to enhancers in EBV transformed lymphoblastoid cells lines (LCLs). Using LCL 3D genome organization map that links EBV enhancers to promoters, we built the most comprehensive virus regulome. EBV regulome contained 1992 genes and enhancers directly linked to them. ~30% of genes essential for LCL growth were linked to EBV enhancers. 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...

(Submitter supplied) Deciphering the molecular pathogenesis of virally induced cancers is challenging due, in part, to the heterogeneity of both viral and host gene expression. Epstein-Barr Virus (EBV) is a ubiquitous herpesvirus prevalent in B-cell lymphomas of the immune suppressed. EBV infection of primary human B cells leads to their immortalization into lymphoblastoid cell lines (LCLs) serving as a model of these lymphomas. 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 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 human B lymphocytes in vitro through expression of viral transcription factors (TFs). These viral TFs activate the expression of key oncogenes, many through long-range enhancer looping. Here we combined various chromatin conformation capture related methods (HiC, HiChIP, 4C-seq etc) to systematically evaluate the effect of EBV infection on host genome-wide 3D organization.

(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) Background: In several types of malignancies, especially EBV-associated nasopharyngeal carcinomas, high Galectin-9 (Gal-9) expression is indicative of an aggressive tumor phenotype. The contribution of Gal-9 to the oncogenesis of B-cell lymphomas (BCLs) has not yet been investigated. Methods: The expression of Gal-9, STING, and EBNA1 was measured by immunohistochemical (IHC) staining on tumor sections from 66 BCL patients. more...

(Submitter supplied) We used Precision Nuclear Run-on followed by Deep Sequencing (PRO-Seq) to investigate RNA Polymerase (Pol) activity during Epstein-Barr Virus (EBV) reactivation in EBV positive Burkitt's lymphoma cell lines Mutu-I and Akata. Nuclei were harvested from latent cells and after treatment with NaB/TPA (Mutu-I) or anti-IgG (akata) to stimulate reactivation at 1 and 4 and 12h. We identified multiple sites on the EBV genome enriched with Pol displaying distinct patterns of activity, which showed an association with CTCF and open chromatin.

(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) Epstein-Barr virus (EBV) infection of primary human B cells drives their indefinite proliferation into lymphoblastoid cell lines (LCLs). B cell immortalization depends on expression of viral latency genes as well as the regulation of host genes. Given the important role of miRNAs in regulating fundamental cellular processes, in this study we assayed changes in host miRNA expression during primary B cell infection by EBV. more...

(Submitter supplied) Epstein-Barr virus (EBV) is a human herpesvirus linked to a number of B cell cancers and lymphoproliferative disorders. During latent infection, EBV expresses 25 viral pre-microRNAs (miRNAs) and induces the expression of specific host miRNAs, such as miR-155 and miR-21, which potentially play a role in viral oncogenesis. To date, a limited number of EBV miRNA targets have been identified; thus, the role of EBV miRNAs in viral pathogenesis is not well defined. more...
