(Submitter supplied) KAT2B (PCAF) belongs to GNAT family of lysine acetyltransferases (KAT), which specifically acetylates histone H3K9 residue and several nonhistone proteins. PCAF is also a transcription coactivator. Due to the lack of PCAF, KAT specific small molecule inhibitor, the exclusive role of the acetyltransferase activity of PCAF is not well understood. Here we report that a hydroxy benzoquinone class of natural compound, embelin, specifically inhibits H3Lys9 acetylation in mice and recombinant PCAF mediated acetylation with near complete specificity in vitro. more...

(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) Gcn5/PCAF dobule knockout (dKO) in MEFs leads to loss of the global H3K9ac, but only affect expression of a small nubmer of genes according to RNA-Seq data. To examine the function of H3K9ac on gene activation, H3K9ac ChIP-Seq was performed. We found that H3K9ac at Transcriptional Start sites (TSSs) of no-changed, up-regulated and down-regulated genes are all dramatially decreased in Gcn5/PCAF dKO cells, suggesting that H3K9ac is largely not required for gene activation.

(Submitter supplied) Type of experiment: The primary focus of these studies is to define the transcriptional network regulated by ectopic expression of the transcriptional co-activator protein, p300, in order to define its mechanism(s) of action in promoting muscle cell survival. Experimental factors: Our laboratory has generated a murine C2-derived myoblast cell line stably expressing an IGF-II cDNA in antisense orientation (C2AS12 cells). more...

(Submitter supplied) We analyzed the transcriptional programs regulated by PCAF and p27 in the colon cancer cell line HCT116 by ChIP-seq. We identified 269 protein-encoding genes that contain both p27 and PCAF binding sites being the majority of these sites different for PCAF and p27

(Submitter supplied) Nerve injury in the peripheral nervous system allows spontaneous regeneration, in contrast to injury of central nerves, which lead to a differential expression pattern of regeneration-associated genes and others. These genes might be regulated by promoter DNA methylation As regeneration model, DRG tissue was analyzed for methyated gene promoters and CpG islands following both injury types. A differential methylation pattern could be identified, although most genes remained unmethylated.

(Submitter supplied) Both epidemiological investigations and animal studies have linked arsenic-contaminated water to cancers, in- cluding skin, liver and lung cancers. Besides genotoxicity, arsenic exposure-related pathogenesis of disease is widely considered through epigenetic mechanisms; however, the underlying mechanism remains to be deter- mined. Herein we explore the initial epigenetic changes via acute sodium arsenite (As) exposures of mouse em- bryonic fibroblast (MEF) cells and histone H3K79 methyltransferase Dot1L knockout (Dot1L−⁠ /−) MEF cells. more...
