Abstract:
Somatic mutations of the CREBBP acetyltransferase are highly recurrent in germinal center (GC)-derived lymphomas, including follicular lymphoma (FL, 60% of cases) and diffuse large B cell lymphoma (DLBCL; 40% of cases in the EZB/C3 genetic subtype). Mutations include prototypical inactivating events that abrogate the C-terminal acetyltransferase (AT) domain, as well as amino-acid changes clustering within this domain, which impair the protein enzymatic activity by decreasing its affinity for acetyl-coenzyme A (Pasqualucci et al., Nature 2011). These events are acquired early during lymphomagen

Abstract:
Abstract Diffuse Large B-cell Lymphoma (DLBCL) is the most common form of non-Hodgkin lymphoma, accounting for ~30% of de-novo diagnoses and also arising as a frequent clinical evolution of indolent lymphomas. Although curable in a substantial fraction of cases, one third of patients do not achieve durable remissions, highlighting the need for novel, targeted therapies. Over the past decade, we and others have identified the CREBBP acetyltransferase and, less frequently, its paralogue EP300 as highly recurrent targets of inactivating somatic mutations/deletions in DLBCL and follicular lymphoma

Abstract Somatic mutations in CREBBP occur frequently in germinal center derived lymphomas such as DLBCL and FL. However whether or how these mutations might contribute to lymphomagenesis is still largely unknown. Most CREBBP mutations are predicted to result in loss of function since they target the histone acetyltransferase (HAT) domain or give rise to premature stop codon prior to the HAT domain. Here, we show that Crebbp shRNA knockdown (KD) accelerated lymphomagenesis in VavP-Bcl2 transgenic mice, a model that recapitulates human GC-derived lymphomas. The median time to lymphoma onset in

Abstract:
Abstract The paralogous histone acetyltransferases EP300 and CREBBP are two of the master regulators of transcription by controlling both enhancer and promoter activity through histone and non-histone acetylation. EP300 and CREBBP activity is primarily driven by their acetylation of K27 and K18 on histone H3 leading to open and active chromatin state. Targeting the EP300/CREBBP axis of chromatin regulation may be a way to disrupt the signaling pathways downstream of key oncogenic signaling networks like MYC/IRF4 in hematopoietic cancers.

Introduction Follicular lymphoma (FL) is typically indolent, but relapses and transformation to higher grade disease are common. FL is often radiosensitive and can show complete response (CR) even to very low dose radiotherapy (VLDRT, 4Gy). There are no known genetic markers of FL radiosensitivity. We sought to identify molecular signatures of FL radiosensitivity to aid in patient selection for VLDRT. Methods We analyzed our institutional database and identified 110 FL patients with 113 tumors treated with radiotherapy (RT) and preexisting MSK-IMPACT, a targeted exon sequencing panel. For each
