(Submitter supplied) Interferon regulatory factor 4 (IRF4) is an IRF family transcription factor with critical roles in lymphoid development and in regulating the immune response. IRF4 binds DNA weakly owing to a carboxy-terminal auto-inhibitory domain, but cooperative binding with factors such as PU.1 or SPIB in B cells increases binding affinity, allowing IRF4 to regulate genes containing ETS–IRF composite elements (EICEs; 5'-GGAAnnGAAA-3'). more...

(Submitter supplied) The transcription factor IRF4 regulates immunoglobulin class switch recombination and plasma cell differentiation. Its differing concentrations appear to regulate mutually antagonistic programs of B and plasma cell gene expression. We show IRF4 to be also required for generation of germinal center (GC) B cells. Its transient expression in vivo induced the expression of key GC genes including Bcl6 and Aicda. more...

(Submitter supplied) Temporal analysis of Irf4 and PU.1 genome binding during B cell activation and differentiation in vitro using antigen (NP-Ficoll) CD40L and IL-2/4/5 cytokines (see Molecular Systems Biology 7:495 for details of cellular system). The results provide insight in the target genes and binding specificity of IRF4 and PU.1 during coordination of different programs of B cell differentiation. Regrettably three of the FASTQ raw sequence files in our study were corrupted during storage. more...

(Submitter supplied) Temporal analysis of B cell activation in vitro using CD40L and IL-2/4/5 cytokines in wild type Irf4+/+ B cells or in mutant Irf4-/- B cells harboring a tet-inducible allele of Irf4. IRF4 expression was restored, or not, in the Irf4-/- background by culturing in the presence of low or high concentrations of doxycycline. The results provide insight in the role of IRF4 expression levels in coordinating different programs of B cell differentiation.

(Submitter supplied) We performed array comparative genomic hybridization (aCGH) and gene expression profiling in 203 samples of diffuse large B cell lymphoma (DLBCL). By gene expression, at least three molecular subtypes of DLBCL termed as germinal center B cell-like (GCB) DLBCL, activated B cell-like (ABC) DLBCL, and primary mediastinal B cell lymphoma (PMBL) can be distinguished. Combining gene expression profiling and aCGH, revealed copy number abnormalities that had strikingly different frequencies in the three molecular DLBCL subtypes. more...

(Submitter supplied) Knowledge of essential oncogenic mutations can inspire therapeutic strategies that are synthetically lethal, affecting cancer cells bearing an oncogenic mutation while sparing normal cells. Lenalidomide is emerging as an active agent in diffuse large B cell lymphoma (DLBCL), especially for the activated B cell-like (ABC) subtype, but the mechanism of its action is unknown. Here we show that lenalidomide kills ABC DLBCL cells by augmenting the production of interferon 3/4, which these cells are predisposed to produce by their oncogenic MYD88 mutations. more...

(Submitter supplied) RNA interference screens identified the transcription factor IRF4 as essential for the survival of the activated B-cell-like subtype of diffuse large B-cell lymphoma (ABC-DLBCL). Analysis of IRF4 genomic targets in ABC-DLBCL and Multiple Myeloma (MM) revealed that IRF4 regulates distinct networks in these cancers. IRF4 peaks in ABC-DLBCL, but not MM, were enriched for a composite ETS-IRF DNA motif that can be bound by heterodimers of IRF4 and the ETS-family transcription factor SPIB, whose expression is also essential for ABC-DLBCL survival. more...

(Submitter supplied) In this study, we used a doxycycline (DOX) inducible gene expression system to introduce MyD88, a gene associated with lymphoma, into the U2932 lymphoma cell line. We performed a transcriptomic analysis (RNA-seq) to identify differentially expressed genes due to the MyD88 L265P oncogenic mutation. This study aimed to investigate the impact of MyD88 L265P oncogenic signaling on lymphoma cells by analyzing the transcriptomic response of model cell lines.

(Submitter supplied) The ABC subtype of diffuse large B cell lymphoma (DLBCL) remains the least curable form of this lymphoma despite recent advances in therapy. We have combined structural and functional genomics to triangulate on new oncogenic mechanisms and devise new therapeutic strategies. RNA interference screen revealed a dependence of ABC DLBCL cell lines on MYD88 and IRAK1. High throughput resequencing of RNA (RNA-Seq) revealed frequent somatic mutations in MYD88 that preferentially occurred in the ABC DLBCL subtype. 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) Variable strengths of T cell receptor (TCR) signaling can produce divergent outcomes for T cell development and function. The mechanisms leading to different outcomes are incompletely understood, but may include distinct activation thresholds for different transcription factors as well as distinct sensitivities among target genes to transcription factors. IRF4 is one transcription factor implicated in responses to variable TCR signal strength. more...

(Submitter supplied) Variable strengths of signaling via the T cell antigen receptor (TCR) can produce divergent outcomes, but the mechanism of this remains obscure. The abundance of the transcription factor IRF4 increases with TCR signal strength, but how this would induce distinct types of responses is unclear. We compared the expression of genes in the TH2 subset of helper T cells to enhancer occupancy by the BATF–IRF4 transcription factor complex at varying strengths of TCR stimulation. more...

(Submitter supplied) Diffuse large B-cell lymphoma (DLBCL) is currently divided into three main molecular subtypes, defined by gene expression profiling (GEP): Germinal Center B-cell like (GCB), Activated B-Cell like (ABC), and Primary Mediastinal B-cell Lymphoma (PMBL). DLBCL subtypes were determined according to patients' gene expression profiles.
