(Submitter supplied) Molecular regulation of stem cell differentiation is exerted through both genetic and epigenetic determinants over distal regulatory or enhancer regions. Understanding the mechanistic action of active or poised enhancers is thus imperative for control of stem cell differentiation. Based on a genome-wide co-occurrence of different epigenetic marks in committed proliferating myoblasts, we have previously generated a 14-state chromatin state model to profile residue-specific histone acetylation in early myoblast differentiation. more...

(Submitter supplied) While skeletal myogenesis is tightly coordinated by myogenic regulatory factors including MyoD and myogenin, chromatin modifications have emerged as vital mechanisms of myogenic regulation. We have previously established that bexarotene, a clinically approved agonist of retinoid X receptor, promotes the specification and differentiation of skeletal muscle lineage. Here, we examine a genome-wide impact of rexinoids on myogenic differentiation through integral RNA-seq and ChIP-seq analyses. more...

(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) Cell fate transitions involve integration of genomic information encoded by regulatory elements, such as enhancers, with the cellular environment. However, identification of the genomic sequences that control the earliest steps of human embryonic development represents a formidable challenge. Here we show that in human embryonic stem cells (hESCs) unique chromatin signatures identify two distinct classes of genomic elements, both of which are marked by the presence of chromatin regulators p300 and BRG1, and monomethylation of histone H3 at lysine 4 (H3K4me1). more...

(Submitter supplied) Deciphering the molecular mechanisms underpinning myoblast differentiation is a critical step in developing the best strategy to promote muscle regeneration in patients suffering from muscle-related diseases. We have previously established that a rexinoid x receptor (RXR)-selective agonist enhances the differentiation and fusion of myoblasts through a direct regulation of MyoD expression, coupled with an augmentation of myogenin protein. more...

(Submitter supplied) The metazoan-specific acetyltransferase p300/CBP is involved in activating signalinduced, enhancer-mediated transcription of cell-type-specific genes. However, the global kinetics and mechanisms of p300/CBP activity-dependent transcription activation remain poorly understood. We performed genome-wide, time-resolved analyses to show that enhancers and super-enhancers are dynamically activated through p300/CBP-catalyzed acetylation, deactivated by the opposing deacetylase activity, and kinetic acetylation directly contributes to maintaining cell identity at very rapid timescales. more...
