(Submitter supplied) Diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma (FL) are the most prevalent B-lymphocyte neoplasms in which abnormal activation of the Bruton’s tyrosine kinase (BTK)–mediated B-cell receptor (BCR) signaling pathway contributes to pathogenesis. Ibrutinib is an oral covalent BTK inhibitor that has shown some efficacy in both indications. To improve ibrutinib efficacy through combination therapy, we first investigated differential gene expression in parental and ibrutinib-resistant cell lines to better understand the mechanisms of resistance. more...

(Submitter supplied) RNAseq profile of TMD8 cell lines resistant to Idelalisib treatment. Idelalisib resistant TMD8 cells were generated by continuous passage in the presence of 1 μM idelalisib for 8 weeks until stable resistance to idelalisib was established. Parallel cultures were grown in the presence of 0.1% DMSO as passage-matched, drug-sensitive control lines. Sensitive and resistant TMD8 cells were clonally isolated through two rounds of single cell limiting dilution

(Submitter supplied) Activated B-cell-like (ABC) and germinal center B-cell-like (GCB) diffuse large B-cell lymphoma (DLBCL) represent the two major molecular DLBCL subtypes. They are characterized by differences in clinical course and by divergent addiction to oncogenic pathways. To determine activity of novel compounds in these two subtypes, we conducted an unbiased pharmacologic in vitro screen. The phosphatidylinositol-3-kinase (PI3K) alpha/delta (PI3Ka/d) inhibitor AZD8835 showed marked potency in ABC DLBCL models, whereas the protein kinase B (AKT) inhibitor AZD5363 induced apoptosis in PTEN-deficient DLBCLs. more...

(Submitter supplied) To determine the global transcriptome changes in mantle cell lymphoma cells following treatment with the BET bromodomain antagonist, JQ1 Mantle Cell Lymphoma (MCL) cells exhibit increased B cell receptor and NFkB activities. The BET protein BRD4 is essential for the transcriptional activity of NFkB. Here, we demonstrate that treatment with the BET protein bromodomain antagonist (BA) JQ1 attenuates MYC and CDK4/6, inhibits the nuclear RelA levels and the expression of NFκB target genes including Bruton’s Tyrosine Kinase (BTK) in MCL cells. more...

(Submitter supplied) RichterTransformation (RT) develops in CLL as an aggressive, therapy resistant diffuse large B cell lymphoma (RT-DLBCL), commonly clonally related (CLR) to the antecedent CLL. Lack of available pre-clinical models has hampered development of novel therapies for RT-DLBCL. Here,we report the profiles of genetic alterations, active enhancers, gene-expressions and anti-lymphoma drug-sensitivity patterns of first-ever established, patient-derived xenograft models of RT-DLBCLs, including CLR and clonally unrelated (CLUR) to antecedent CLL. more...

(Submitter supplied) Pathologic activation of the Toll-like receptor (TLR) pathway underlies various human disorders such as autoimmune diseases, chronic inflammatory diseases and lymphoid malignancies. Current therapy of these diseases relies on immunosuppressive or chemotherapeutic agents, but more effective therapeutics tailored to disease-causing mechanisms are needed. Pivotal to TLR signaling is the IL-1 receptor-associated kinase 4 (IRAK4), which is recruited to TLRs by the adaptor protein MyD88. more...

(Submitter supplied) B cell receptor (BCR) signaling has emerged as a therapeutic target in B cell lymphomas, but the precise deployment of inhibitors to target oncogenic BCR signaling requires detailed knowledge of the signaling cascades that the BCR triggers in individual tumors. Here, we have used CRISPR-Cas9 screens to investigate whether the ABC and GCB molecular subtypes of diffuse large B cell lymphoma (DLBCL) utilize distinct BCR signaling modes to sustain their proliferation and survival. 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...
