The researchers tested the mutant CARD11 proteins in other cell lines and found that the proteins spontaneously activated the NF-kB signaling pathway, thereby promoting the survival of malignant cells. (nih.gov)
All cases were previously characterized by the Molecular Mechanisms of Malignant Lymphoma 6 consortium using the Affymetrix GeneChip technology (gold standard of classification). (ashpublications.org)

In the Revised European-American Lymphoma (REAL) classification, except in morphologic descriptions, the schema includes immunologic, cytogenetic, and molecular information in order to define distinct lymphoma entities. (medscape.com)

Preeminent among these proteins are the cyclin dependent kinases, which upon binding to cyclins, phosphorylate numerous targets to trigger cell cycle progression. (smadpathway.com)
Cyclin-dependent kinase (cdk) inhibitors have the potential to induce growth arrest and apoptosis in cancer cells. (omecamtivmecarbilactivator.com)
We report a case of diffuse large B-cell lymphoma with cyclin D1 expression. (biomedcentral.com)
However, rare DLBCLs may show cyclin D1 expression in absence of t (11,14)(q13;q23) or SOX11 expression. (biomedcentral.com)

Earlier classifications subdivided diffuse large B-cell lymphomas (DLBCLs) either by morphology or by the biologic behavior. (medscape.com)
The 2 divergent classifications were 1 case of mBL that was classified as intermediate and 1 case of an intermediate that was classified as mBL [both lymphomas carried a t(8;14) translocation]. (ashpublications.org)
Compared with the array, 5 of 31 (16%) non-mBL/DLBCLs received different molecular classifications using DMGE and FFPE-derived RNA ( Figure 1B ). (ashpublications.org)

The WHO classification of hematologic malignancies uses an updated version of the Revised European-American Lymphoma (REAL) classification for lymphoid neoplasms. (medscape.com)
Diffuse large B cell lymphomas (DLBCLs) are genetically heterogeneous and highly proliferative neoplasms derived from germinal center (GC) B cells. (ckbiobank.org)

PU-H71 Researchers, including scientists from Weill Cornell Medical College , have now discovered that the heat shock protein inhibitor, PU-H71, selectively kills DLBCLs that depend on the B-cell lymphoma 6 protein (BCL-6) transcriptional repressor. (drugdiscoveryopinion.com)

The highly divergent C-terminal half of MEF2 proteins has been suggested to modulate their transcriptional activity17 18 The spectrum of targets activated by MEF2 transcription factors in different cell types is dependent on association with specific co-repressors and co-activators in response to multiple signaling pathways17. (researchassistantresume.com)
However, AID-induced demethylation is markedly impaired in TET2-deficient GC B cells, suggesting that AID epigenetic effects are partially dependent on TET2. (c3m-nice.fr)
in ABC-DLBCLs is usually often dependent on oxidative stress, rather than DNA damage response. (cgp60474.com)
This expression was dependent on activation of either NF-κB, JAK1/JAK2 or BTK pathways since these pathways were activated in tumor B-cells and ex vivo treatment with the inhibitory molecules PHA-408, ruxolitinib and ibrutinib led to decrease of its expression. (springer.com)
Laboratory studies shown that the growth of neoplastic B cells is definitely stimulated by tumor-infiltrating illness results in T cell-dependent reactions through the classic germinal center reaction, and thus produces reactive B and T cells. (californiaehealth.org)

NF-κB, one of the most cited transcription factor in B-cell lymphomas, is able to increase tumor cell expression of PD-L1 either directly or indirectly [ 3 ]. (springer.com)
However, most GEP studies have typically been performed on whole tissue samples, containing varying degrees of tumor cell content, which results in uncertainties in data analysis. (lu.se)

Here, we show that overexpression of AICDA causes more aggressive disease and worse outcome in BCL2-driven murine lymphomas. (mskcc.org)
Affected regions significantly overlapped with those found in murine AICDA-overexpressing lymphomas. (mskcc.org)
Here we show that AICDA overexpression causes more aggressive disease in BCL2-driven murine lymphomas. (cornell.edu)
