Structure-specific recognition protein-1 (SSRP1) is a histone chaperone which is important for chromatin-associated processes such as transcription, DNA replication and repair. Since the function of SSRP1 during cell differentiation remains unclear, we investigated its potential role in controlling lineage determination. Depletion of SSRP1 in human mesenchymal stem cells elicited lineage-specific effects by increasing expression of adipocyte-specific genes and decreasing the expression of osteoblast-specific genes. Consistent with a role in controlling lineage specification, transcriptome-wide RNA-sequencing following SSRP1 depletion and the induction of osteoblast differentiation revealed a specific decrease in the expression of genes involved in biological processes related to osteoblast differentiation. Importantly, we observed a specific downregulation of target genes of the canonical Wnt signaling pathway, which was accompanied by decreased nuclear localization of active beta-catenin. Together our data uncover a previously unknown role for SSRP1 in promoting the activation of the Wnt signaling pathway activity during cellular differentiation."],["dc.identifier.doi","10.1002/stem.2287"],["dc.identifier.isi","000375896900021"],["dc.identifier.pmid","27146025"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/40740"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Wiley-blackwell"],["dc.relation.issn","1549-4918"],["dc.relation.issn","1066-5099"],["dc.title","Histone Chaperone SSRP1 is Essential for Wnt Signaling Pathway Activity During Osteoblast Differentiation"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

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"]]

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.
