(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) 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) In B cells infected by the cancer-associated Epstein-Barr virus (EBV), RUNX3 and RUNX1 transcription is manipulated to control cell growth. The EBV-encoded EBNA2 transcription factor (TF) activates RUNX3 transcription leading to RUNX3-mediated repression of the RUNX1 promoter and the relief of RUNX1-directed growth repression. We show that EBNA2 activates RUNX3 through a specific element within a -97 kb super-enhancer in a manner dependent on the expression of the Notch DNA-binding partner RBP-J. more...

(Submitter supplied) Epstein-Barr-Virus (EBV) Nuclear Antigens EBNALP and EBNA2 are co-expressed in EBV infected B-lymphocytes and are critical for Lymphoblastoid Cell Line (LCL) growth. EBNALP removes NCOR1 and RBPJ repressive complexes from promoter and enhancer sites and EBNA2 mostly activates transcription from distal enhancers. ChIP-seqs found EBNALP at 19,224 LCL sites, which were 33% promoter associated. EBNALP was associated with 10 transcription factor (TF) clusters that included YY1(63%), SP1(62%), PAX5(59%), BATF(50%), IRF4(49%), RBPJ(43%), ETS1(39%), PU.1(37%), RAD21(33%), NF-kB(31%), TBLR1(26%), ZNF143(24%), CTCF(23%), SMC3(21%), and EBF(17%). more...

(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) 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) Marginal zone B-cell lymphomas (MZL) have been divided into three distinct subtypes (extranodal MZL of MALT type, nodal MZL; splenic MZL). Nevertheless, the relationship between them is still unclear. We performed a comprehensive analysis of genomic DNA copy number changes in a very large series of MZL cases with the aim of addressing this question. Samples from 218 MZL patients (25 nodal, 57 MALT, 134 splenic and two not better specified MZL) were analyzed with the Affymetrix Human Mapping 250K SNP arrays, and the data combined with matched gene expression in 33/218 cases. more...

(Submitter supplied) Epstein-Barr virus nuclear antigen 2 (EBNA2) is a transactivator of viral and cellular gene expression, which plays a critical role in the Epstein-Barr virus-associated diseases. It was reported that EBNA2 regulates gene expression by manipulating epigenetics, but the details are unclear. Recent studies showed that liquid-liquid phase separation plays an essential role in epigenetic and transcriptional regulation. more...

(Submitter supplied) In CLL, NOTCH1 is the most commonly mutated gene at diagnosis and it is associated with a poor outcome. The mechanisms underlying how NOTCH1 contributes to disease progression, resistance to treatment and Richter’s transformation remain largely unknown. Data suggests a link between BCR activation and NOTCH1 signalling so the main goal of this study is to compare the gene expression profile of primary CLL cells transduced with the intracellular part of NOTCH1 lacking of the PEST domain vs cells transduced with an empty vector following IgM stimulation.

(Submitter supplied) Notch signaling is the dominant intercellular signaling input during the earliest stages of T cell development in the thymus. Although Notch1 is known to be indispensable, we show that it does not mediate all Notch signaling in pre-commitment stages: Notch2 initially works in parallel to promote early murine T cell development and antagonize other fates. Notch-regulated target genes before and after T-lineage commitment change dynamically, and we show that this partially reflects shifts in genome-wide DNA binding by RBPJ, the transcription factor activated by complex formation with the Notch intracellular domain. more...

(Submitter supplied) Generation of effective immune responses requires expansion of rare antigen-specific CD4+ T cells. The magnitude of the response is ultimately determined by proliferation and survival. Both processes are tightly controlled to limit responses to innocuous antigens. Sustained expansion occurs only when innate immune sensors are activated by microbial stimuli or by adjuvants, which has important implications for vaccination. more...
