(Submitter supplied) The activation of stress response pathways in synovial fibroblasts (SF) is a hallmark of rheumatoid arthritis (RA). CBP and p300 are two highly homologous histone acetyl transferases and writers of activating histone 3 lysine 27 acetylation (H3K27ac) marks. We investigated individual functions of CBP and p300 using a silencing strategy, followed by RNA-sequencing, and pathway enrichment analysis. We have selected stress-related pathways for a further in-depth investigation of individual functions of CBP and p300 in SF. more...

(Submitter supplied) C4-2B prostate cancer cells were transfected with siRNA against a non-specific (NS) sequence, siRNA specifically targeting EP300, or siRNA specifically targeting CREBBP. We tested the hypothesis that their exists different subgroups of genes that are preferentially affected by p300 or CBP depletion.

(Submitter supplied) CBP/p300 are transcription co-activators whose binding is a signature of enhancers, cis-regulatory elements that control patterns of gene expression in multicellular organisms. Active enhancers produce bi-directional enhancer RNAs (eRNAs) and display CBP/p300 dependent histone acetylation. Here, we demonstrate that CBP binds directly to RNAs in vivo and in vitro. RNAs bound to CBP in vivo include a large number of eRNAs. more...

(Submitter supplied) We performed genome-wide expression profiling analysis to define the genes underlying the synthetic-lethal relationship between CBP and p300. We extracted 1,936 genes whose expression levels changed >2-fold upon p300-knockdown (KD) in CBP-KO cells, or upon CBP-KD in p300-KO cells, but not in either KD in wild-type cells

(Submitter supplied) We investigated the impact in transcription, chromatin acetylation and behavior of eliminating either CBP or p300 in excitatory neurons of the adult forebrain. The elimination of CBP reduced the expression of plasticity genes. The importance of CBP became more prominent in paradigms that involved a chronic or recurrent change in transcription, including kindling and neuroadaptation to environmental enrichment, in which CBP loss interfered with the establishment of activity-induced transcriptional and epigenetic adaptive changes in response to stimulus or experience. more...

(Submitter supplied) Genome-wide distribution of histone H3K18 and H3K27 acetyltransferases, Crebbp (CBP) and Ep300 (p300), is used to map enhancers and promoters, but whether these elements functionally require CBP/p300 remains largely uncertain. We investigated this relationship by comparing genomic CBP recruitment with gene expression in wild type and CBP/p300 double-knockout fibroblasts. ChIP-seq revealed nearby CBP recruitment for 20 percent of constitutively expressed genes, but surprisingly, three-quarters of these were unaffected or slightly activated by CBP/p300 deletion. more...

(Submitter supplied) Silencing of the somatic cell-type specific gene expression programs is a critical yet poorly understood step in nuclear reprogramming. To uncover chromatin-related pathways important for maintaining cell identity, we carried out a reprogramming screen using inhibitors of chromatin factors. Here we identify two independent acetyl-lysine competitive inhibitors targeting the bromodomains of coactivators EP300 and CBP as potent enhancers of reprogramming. more...
