Analysis of hippocampi from heterozygous p300 deletion animals. A small percentage of cases of Rubinstein-Taybi syndrome (RSTS) is caused by p300 mutations. Results provide insight in the contribution of p300 to RSTS pathoetiology.

(Submitter supplied) Rubinstein-Taybi syndrome (RSTS) is a complex autosomal-dominant disease characterized by mental and growth retardation and skeletal abnormalities. A majority of the individuals diagnosed with RSTS carry heterozygous mutation in the gene CREBBP, but a small percentage of cases are caused by mutations in EP300. To investigate the contribution of p300 to RSTS pathoetiology, we carried out a comprehensive and multidisciplinary characterization of p300+/- mice. more...

(Submitter supplied) Rubinstein-Taybi syndrome (RSTS) is a rare multisystem developmental disorder with moderate to severe intellectual disability caused by heterozygous mutations of either CREBBP or EP300 genes encoding CBP/p300 chromatin modifiers. We explored the gene programs and processes underlying the morphological and functional alterations shown by iPSC-derived neurons modeling RSTS to bridge the molecular changes resulting from defective CBP/p300 to cognitive impairment. more...

(Submitter supplied) Early placenta development involves cytotrophoblast differentiation into extravillous trophoblast (EVT) and syncytiotrophoblast (STB). Defective trophoblast development and function may result in severe pregnancy complications, including fetal growth restriction and pre-eclampsia. The incidence of these complications is increased in pregnancies of fetuses affected by Rubinstein–Taybi syndrome, a developmental disorder predominantly caused by heterozygous mutations in CREB-binding protein (CREBBP) or E1A-binding protein p300 (EP300). more...

(Submitter supplied) We have performed RNA-seq on mouse islets lacking all p300 (p300 KO), all CBP (CBP-null), and one copy of CBP and all p300 (triallelic). The data revealed that p300 and CBP regulate some distinct but largely overlapping genes in islets. This was further confirmed by GO term and transcription factor target analyses, which suggested that these coactivators regulate genes that function similarly and converge to Hnf1a pathway.

(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) Reversible ε-amino acetylation of lysine residues regulates transcription as well as metabolic flux; however, roles for specific lysine acetyltransferases in skeletal muscle physiology and function is unknown. In this study, we investigated the role of the related acetyltransferases p300 and CBP in skeletal muscle transcriptional homeostasis and physiology in adult mice. These data reveal that p300 and CBP are required for the control and maintenance of contractile function and transcriptional homeostasis in skeletal muscle, and ultimately, organism survival.

(Submitter supplied) Polycomb group (PcG) proteins are evolutionarily conserved chromatin-modifying factors that regulate gene expression to control tissue development. We previously discovered an AUTS2?Polycomb complex activates gene expression by recruiting Casein kinase 2 (CK2) and P300. But the mechanisms underlying the recruitment of AUTS2-PRC1 to chromatin and the physiological relevance of AUTS2-P300 interaction during neurodevelopment remain unknown. more...

(Submitter supplied) Histone hyperacetylation is thought to drive the replacement of histones by transition proteins that occurs in elongating spermatids after a general shut-down of transcription. The molecular machineries underlying this histone hyperacetylation remain still undefined. Here we focused our attention on the role of Cbp and p300 in histone hyperacetylation and in the preceding late gene transcriptional activity in elongating spermatids. 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...
