(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) 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...

Analysis of Epstein-Barr virus (EBV) negative B-cell lines BL41K3 and BJABK3 following activation of EBV nuclear antigen 2 (EBNA-2). EBNA-2 fused to the hormone-binding domain of the estrogen receptor, and EBNA-2 activated upon estrogen binding. Results identify EBNA-2 target genes.

(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) 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) 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) 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) 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) EBNA-1 is expressed in all EBV-associated malignancies and may play a role in transcription regulation through its DNA binding ability. This is our attempt to examine the effect of EBNA-1 on the expression of cellular genes. We have compared the transcription profiles of conditional and stable EBNA-1 transfected sublines of the EBV negative B-cell lymphoma BJAB where EBNA-1 was expressed for few days, few months or years. more...

(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...

Lymphoid B cells from centenarians were more resistant to apoptosis induction and displayed a more developed lysosomal compartment, the most critical component of phagic machinery. 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...
