(Submitter supplied) Inactivating mutations of the CREBBP acetyltransferase and, at lower frequencies, its paralogue EP300 are among the most common genetic alterations in diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma (FL), the two most frequent B cell malignancies. Here we uncover unexpected distinct functions for CREBBP and EP300 in the germinal center (GC), i.e. the target structure for most human B cell lymphomas. more...

(Submitter supplied) Purpose: Diffuse large B cell lymphomas (DLBCL) frequently harbor mutations in the histone acetyltransferase CREBBP, however their functional contribution to lymphomagenesis remains largely unknown. This study aims at elucidating and characterizing the molecular pathways affected by mutations in CREBBP. Methods: U2932, a DLBCL cell line that has wild type expression of CREBBP was manipulated by CRISPR-Cas9 strategy to mutate one allele of CREBBP and examine the pathways affected. more...

(Submitter supplied) Inactivating mutations of the gene encoding for the CREBBP acetyltransferase are highly frequent in diffuse large B cell lymphoma (DLBCL, 30% of cases) and follicular lymphoma (FL, 60% of cases), the two most common cancers derived from the germinal-center (GC). However, the role of CREBBP inactivation in lymphomagenesis remains unclear. Using functional epigenomics and mouse genetics, here we define the program modulated by CREBBP in primary human GC B cells and show that CREBBP regulates enhancer/super-enhancer networks, with specific roles in GC/post-GC cell fate decisions. more...

(Submitter supplied) Diffuse large B-cell lymphoma (DLBCL), the most common form of lymphoma in adulthood, comprises multiple biologically and clinically distinct subtypes including germinal center B cell-like (GCB) and activated B cell like (ABC) DLBCL. Gene expression profile studies have shown that its most aggressive subtype, ABC-DLBCL, is associated with constitutive activation of the NF-kB transcription complex. However, except for a small fraction of cases, it remains unclear whether NF-kB activation in these tumors represents an intrinsic program of the tumor cell of origin or a pathogenetic event. more...

(Submitter supplied) Somatic mutations affecting CREBBP and EP300 are a hallmark of Diffuse Large B Cell Lymphoma (DLBCL). These mutations are frequently monoallelic, within the histone acetyltransferase (HAT) domain and usually mutually exclusive, suggesting that they might affect a common pathway and their residual WT expression is required for cell survival. Using in vitro and in vivo models, we found that inhibition of CARM1 activity (CARM1i) slows DLBCL growth and that the levels of sensitivity are positively correlated with the CREBBP/EP300 mutation load. more...

(Submitter supplied) Inactivating mutations of the KMT2D methyltransferase and the CREBBP acetyltransferase are among the most common genetic alterations in B-cell lymphoma and co-occur in 40-60% of follicular lymphoma (FL) and diffuse large B cell lymphoma (DLBCL) cases, suggesting they may be co-selected. Here we show that combined germinal center (GC)-specific haploinsufficiency of Crebbp and Kmt2d synergize in vivo to promote the expansion of abnormal GCs, a common pre-neoplastic event. more...

(Submitter supplied) We confirmed that common CREBBP mutations in human FL result in reduced acetyltransferase activity of the protein, and modeled this loss of function by B-cell-specific deletion of one or both alleles of Crebbp in transgenic mouse models. We show that Crebbp deletion results in deficits in B-cell development, and provide the first evidence from transgenic mouse models that Crebbp inactivation can cooperate with Bcl2 over-expression to promote B-cell lymphoma. more...
