Project description:ChIP-seq. analysis of TCam-2 16 h after 10 nanomolar Romidepsin application. DMSO treated cells were used as controls. For ChIP, an antibody against histone H3 pan-acetylation was used. These data are part of the article 'The Histone Deacetylase Inhibitor Romidepsin Efficiently Targets Cisplatin-resistant Germ Cell Cancer Cells via Downregulation of the SWI/SNF-Complex Member ARID1A' (Nettersheim et al., 2016).

Project description:Identifying tissue and condition-specific gene regulatory elements and the mechanisms by which they associate with their target genes in human cells remains a significant challenge, largely due to the vast amount of non-protein-coding sequence in the human genome. Despite increasing evidence of physical interactions between distant regulatory regions and gene promoters in a variety of mammalian cell types, many searches for regulatory regions still consider only genomic regions proximal to the gene promoter. We identify a set of putative cis-regulatory modules (CRMs) of human skeletal muscle differentiation by combining new ChIP-chip data measuring the binding of myogenic TFs MyoG, MyoD, and SRF over the timecourse of differentiation with previously generated histone modification data. A substantial proportion of these putative CRMs are located distant (> 20 kb) from muscle gene promoters, and these distantly located CRMs are more likely than proximal promoter regions to show differentiation-specific changes in myogenic TF binding. Examination of two distant CRMs, which were previously shown to activate transcription in differentiating muscle cells, revealed that they interact physically with their upstream or downstream gene promoters (PDLIM3 and ACTA1) specifically upon myogenic differentiation. Our results highlight the importance of considering CRMs located distant from their target genes in investigations of mammalian gene regulation and further support the hypothesis that enhancer-promoter looping contacts are a general mechanism of regulation by distant CRMs.
Project description:Polycomb-mediated chromatin repression modulates gene expression during development in metazoans. Binding of multiple sequence-specific factors at discrete Polycomb Response Elements (PREs) is thought to recruit repressive complexes that spread across an extended chromatin domain. To dissect the structure of PREs, we applied high-resolution mapping of non-histone chromatin proteins in native chromatin of Drosophila cells. Analysis of occupied sites reveal cooperative interactions between transcription factors that stabilize Polycomb anchoring to DNA, and implicate the general transcription factor Adf1 as a novel PRE component. By comparing two Drosophila cell lines with differential chromatin states, we provide evidence that repression is accomplished at multiple steps in transcription, including inactivation of distant enhancers, enhanced Polycomb recruitment to PREs and target promoters, and elevated stalling of RNAPII in repressed genes. These results suggest that the stability of complexes bridging promoters, enhancers, and PREs is a crucial aspect of developmentally regulated gene expression.
