Because of this association, it has been commonly assumed that H2Bub1 is an exclusively positively acting histone modification and that increased H2Bub1 occupancy correlates with increased gene expression. In contrast, depletion of the H2B ubiquitin ligases RNF20 or RNF40 alters the expression of only a subset of genes. Results: Using conditional Rnf40 knockout mouse embryo fibroblasts, we show that genes occupied by low to moderate amounts of H2Bub1 are selectively regulated in response to Rnf40 deletion, whereas genes marked by high levels of H2Bub1 are mostly unaffected by Rnf40 loss. Furthermore, we find that decreased expression of RNF40-dependent genes is highly associated with widespread narrowing of H3K4me3 peaks. H2Bub1 promotes the broadening of H3K4me3 to increase transcriptional elongation, which together lead to increased tissue- specific gene transcription. Notably, genes upregulated following Rnf40 deletion, including Foxl2, are enriched for H3K27me3, which is decreased following Rnf40 deletion due to decreased expression of the Ezh2 gene. As a consequence, increased expression of some RNF40-\"suppressed\" genes is associated with enhancer activation via FOXL2. Conclusion: Together these findings reveal the complexity and context-dependency whereby one histone modification can have divergent effects on gene transcription. Furthermore, we show that these effects are dependent upon the activity of other epigenetic regulatory proteins and histone modifications."],["dc.identifier.doi","10.1186/s13059-017-1159-5"],["dc.identifier.isi","000394828000003"],["dc.identifier.pmid","28209164"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/14250"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/43221"],["dc.notes.intern","Merged from goescholar"],["dc.notes.intern","In goescholar not merged with http://resolver.sub.uni-goettingen.de/purl?gs-1/14993 but duplicate"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","PUB_WoS_Import"],["dc.publisher","Biomed Central Ltd"],["dc.relation.issn","1474-760X"],["dc.rights","CC BY 4.0"],["dc.rights.access","openAccess"],["dc.rights.holder","The Author(s)."],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.title","RNF40 regulates gene expression in an epigenetic context-dependent manner"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

BRD4 plays a central role in promoting the expression of select subsets of genes including many driven by oncogenic transcription factors and signaling pathways. However, the role of BRD4 and the effects of BET inhibitors in non-transformed cells remain mostly unclear. We demonstrate that BRD4 is required for the maintenance of a basal epithelial phenotype by regulating the expression of epithelial-specific genes including TP63 and Grainy Head-like transcription factor-3 (GRHL3) in non-transformed basal-like mammary epithelial cells. Moreover, BRD4 occupancy correlates with enhancer activity and enhancer RNA (eRNA) transcription. Motif analyses of cell context-specific BRD4-enriched regions predicted the involvement of FOXOtranscription factors. Consistently, activation of FOXO1 function via inhibition of EGFR-AKT signaling promoted the expression of TP63 and GRHL3. Moreover, activation of Src kinase signaling and FOXO1 inhibition decreased the expression of FOXO/BRD4 target genes. Together, our findings support a function for BRD4 in promoting basal mammary cell epithelial differentiation, at least in part, by regulating FOXO factor function on enhancers to activate TP63 and GRHL3 expression."],["dc.identifier.doi","10.1093/nar/gkw1276"],["dc.identifier.isi","000398376200026"],["dc.identifier.pmid","27980063"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/14764"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/42778"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","PUB_WoS_Import"],["dc.publisher","Oxford Univ Press"],["dc.relation.issn","1362-4962"],["dc.relation.issn","0305-1048"],["dc.rights","CC BY-NC 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by-nc/4.0"],["dc.title","BRD4 promotes p63 and GRHL3 expression downstream of FOXO in mammary epithelial cells"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Longstanding challenges in resolving this functional dichotomy may uncover new strategies to treat advanced carcinomas. The Kruppel-like transcription factor, KLF10, is a pivotal effector of TGF beta/SMAD signaling that mediates antiproliferative effects of TGF beta. In this study, we show how KLF10 opposes the prometastatic effects of TGFb by limiting its ability to induce epithelial-to-mesenchymal transition (EMT). KLF10 depletion accentuated induction of EMT as assessed by multiple metrics. KLF10 occupied GC-rich sequences in the promoter region of the EMT-promoting transcription factor SLUG/SNAI2, repressing its transcription by recruiting HDAC1 and licensing the removal of activating histone acetylation marks. In clinical specimens of lung adenocarcinoma, low KLF10 expression associated with decreased patient survival, consistent with a pivotal role for KLF10 in distinguishing the antiproliferative versus prometastatic functions of TGFb. Our results establish that KLF10 functions to suppress TGFb-induced EMT, establishing a molecular basis for the dichotomy of TGFb function during tumor progression.

A body of work suggests roles for the developmental Wnt signalling pathway in cardiac remodelling. Hitherto, there is no evidence supporting a direct role of Wnt nuclear components in regulating chromatin landscapes in this process. We show that transcriptionally active, nuclear, phosphorylated(p)Ser675-β-catenin and TCF7L2 are upregulated in diseased murine and human cardiac ventricles. We report that inducible cardiomyocytes (CM)-specific pSer675-β-catenin accumulation mimics the disease situation by triggering TCF7L2 expression. This enhances active chromatin, characterized by increased H3K27ac and TCF7L2 occupancies to cardiac developmental and remodelling genes in vivo. Accordingly, transcriptomic analysis of β-catenin stabilized hearts shows a strong recapitulation of cardiac developmental processes like cell cycling and cytoskeletal remodelling. Mechanistically, TCF7L2 co-occupies distal genomic regions with cardiac transcription factors NKX2–5 and GATA4 in stabilized-β-catenin hearts. Validation assays revealed a previously unrecognized function of GATA4 as a cardiac repressor of the TCF7L2/β-catenin complex in vivo, thereby defining a transcriptional switch controlling disease progression. Conversely, preventing β-catenin activation post-pressure-overload results in a downregulation of these novel TCF7L2-targets and rescues cardiac function. Thus, we present a novel role for TCF7L2/β-catenin in CMs-specific chromatin modulation, which could be exploited for manipulating the ubiquitous Wnt pathway."],["dc.description.sponsorship","Open-Access-Publikatinsfonds 2018"],["dc.identifier.doi","10.1093/nar/gky049"],["dc.identifier.gro","3142314"],["dc.identifier.pmid","29394407"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/15089"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/13447"],["dc.identifier.url","https://sfb1002.med.uni-goettingen.de/production/literature/publications/201"],["dc.language.iso","en"],["dc.notes.intern","lifescience updates Crossref Import"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.relation","SFB 1002: Modulatorische Einheiten bei Herzinsuffizienz"],["dc.relation","SFB 1002 | A11: Absolute Arrhythmie bei Vorhofflimmern - ein neuer Mechanismus, der zu einer Störung von Ca2+-Homöostase und elektrischer Stabilität in der Transition zur Herzinsuffizienz führt"],["dc.relation","SFB 1002 | C07: Kardiomyozyten Wnt/β-catenin Komplex Aktivität im pathologischen Herz-Remodeling - als gewebespezifischer therapeutischer Ansatz"],["dc.relation","SFB 1002 | S01: In vivo und in vitro Krankheitsmodelle"],["dc.relation","SFB 1002 | S02: Hochauflösende Fluoreszenzmikroskopie und integrative Datenanalyse"],["dc.relation","SFB 1002 | INF: Unterstützung der SFB 1002 Forschungsdatenintegration, -visualisierung und -nachnutzung"],["dc.relation.issn","0305-1048"],["dc.relation.workinggroup","RG Hasenfuß (Transition zur Herzinsuffizienz)"],["dc.relation.workinggroup","RG T.
