Expression data from WT, Crebbp+/- and Ep300+/- bone marrow stroma

Project description:We found that the bone marrow microenvironment of Crebbp+/- mice was unable to properly maintain the immature stem - and progenitor pools. Instead, it stimulates myeloid differentiation that progresses into a myeloproliferative-like disease. Since CREBBP is a transcriptional co-activator, we used gene expression analysis to globally assess functional deficiencies in Crebbp+/- bone marrow stroma cells at a molecular level. Ep300 encodes a protein which is highly similar in structure and function to CREBBP; nevertheless, Ep300+/- mice suffer neither excessive myeloid differentiation nor loss of HSCs. Therefore, to identify expression changes specifically related to Crebbp heterozygosity, we focused on genes that showed significant differences in expression levels between Crebbp+/- and wild-type bone marrow stroma but no difference between Ep300+/- and wild-type. Bone marrow stroma was established from wild-type, Crebbp+/- and Ep300+/- mice that were 3-4 months old for RNA extraction and hybridization on Affymetrix microarrays. There are 4 biological replicates for each genotype used.

H3K27Ac mapping in isogenic CREBBP-WT, CREBBP-KO and EP300-KO SUDHL4 cell lines

Project description: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. We show that these proteins modulate non-overlapping transcriptional programs that are preferentially enriched in biological functions associated with the separate anatomic compartments of the GC. Consistently, deletion of CREBBP or EP300 have opposing effects on GC formation in vivo. Nonetheless, these proteins partially compensate for each other to maintain a minimal threshold of acetyltransferase activity and guarantee homeostatic control of the GC, which is completely abrogated by their combined loss. This synthetic lethal interaction is retained in DLBCL cells, identifying an Achille’s heel in CREBBP-mutant lymphomas that could be pharmacologically targeted by using a novel, selective small molecule inhibitor of the CREBBP/EP300 bromodomain. These data shed light on the unique roles of CREBBP and EP300 in the physiology and pathology of GC B cells, and provide a proof-of-principle for the development and testing of EP300 inhibition as a therapeutic strategy in these diseases.

MYC-mediated ribosomal gene expression sensitizes enzalutamide-resistant cells to EP300/CREBBP inhibitors

Project description:Various mechanisms have been reported to be responsible for enzalutamide resistance in prostate cancer. In our previous studies, we have demonstrated that the histone acetyltransferase EP300 is highly expressed in castration therapy-resistant prostate cancer. In the present study, we investigated the role of EP300/CREBBP in enzalutamide-resistant prostate cancer. Enzalutamide resistant and control DuCaP cells generatd previously were treated with histone acetyltransferase (C646) and bromodomain (I-CBP112) inhibitors of EP300/CREBBP. Additionally Enzalutamide resistant cells under 5 µM enzalutamide treatment and control LNCaP cells were analyzed. DuCaP and LNCaP cells were seeded in 6-well-plates at 8 x 10^5 and 6 x 10^5 cells per well. The following day, DuCaP cells were treated with 8 µM enzalutamide, 10 µM C646, 10 µM I-CBP112 or DMSO equivalent for 24 hr.
