(Submitter supplied) Eptstein-Barr Virus, an oncogenic herpesvirus, infects and immortalizes human B cells in culture into indefinitely-proliferating LCLs. We examined the gene expression of primary B cells during the process of infection and growth transformation at the exon level to analyze early and late virus-induced changes in expression and exon usage.

(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) causes endemic Burkitt lymphoma and immunosuppression-related lymphomas. These B-cell malignancies arise by distinct transformation pathways and utilize divergent viral and host expression programs. To identify host dependency factors elicited by EBV latent-infection states, we performed parallel genome-wide CRISPR/Cas9 screens in Burkitt lymphoma (BL) and lymphoblasotid cell lines (LCL). 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 (EBV) Latent Membrane Protein 1 (LMP1) transforms rodent fibroblasts and is expressed in most EBV-associated malignancies. LMP1 Transformation Effector Site 2 (TES2)/C-Terminal Activation Region 2 (CTAR2) activates NF-kappaB, p38, JNK, ERK and IRF7 pathways. We have investigated LMP1 TES2 genome-wide RNA effects at 4 time points after LMP1 TES2 expression in HEK 293 cells. Using a False Discovery Rate (FDR) of < 0.001 after correction for multiple hypotheses, LMP1 TES2 caused > 2-fold changes in 1916 mRNAs; 1479 RNAs were up-regulated and 437 down-regulated. more...

(Submitter supplied) RNA-seq was used to characterize the LMP1 mediated regulation of host target gene regulation. Here, we stably expressed doxycycline-induced HA-tagged wildtype (WT) LMP1 or TES1 mutant (TES1m) oe TES2 mutant(TES2m) in GM12878 LCL. We then depleted LMP1 from these cells using CRISPR-Cas9 approach and treated the cells with 400ng/ml of doxycycline to induce expression of WT, TES1m or TES2m LMP1 to rescue from the LMP1 depletion mediated effects (including loss of cell viability) to understand and differenciate the role of LMP1 TES1 vs TES2 domains in LCL.

(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) 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) Epstein-Barr virus (EBV) is an oncogenic virus that is associated with the pathogenesis of several human lymphoid malignancies, including Hodgkin's lymphoma. Infection of normal resting B cells with EBV results in activation to lymphoblasts that are phenotypically similar to those generated by physiological stimulation with CD40L plus IL-4. One important difference is that infection leads to the establishment of permanently growing lymphoblastoid cell lines, whereas CD40L/IL-4 blasts have finite proliferation life-spans. more...

(Submitter supplied) Early after infection, Epstein-Barr Virus (EBV) induces a transient period of hyper-proliferation that is suppressed by the activation of the DNA damage response and a G1/S phase growth arrest. This growth arrest prevents long-term outgrowth of the majority of infected cells. We developed a method to isolate and characterize infected cells that arrest after this early burst of proliferation. We used microarray analysis to uncover changes in gene expression that could give us a better understanding of the pathways that attenuate immortalization.

(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) Whether the human tumor virus, Epstein-Barr virus (EBV) promotes breast cancers remains controversial and a potential mechanism has remained elusive. Here we show EBV can infect primary mammary epithelial cells (MECs) that express the attachment receptor, CD21. EBV infection leads to the expansion of early MEC progenitor cells with a stem cell phenotype and enforces a differentiation block. When MECs were implanted as xenografts, EBV infection cooperated with activated Ras and accelerated the formation of breast cancer. more...
