Including: H4K5ac antibody, control rabbit IgG, and positive primer set. The ChIP Validated H4K5ac Antibody with Positive Primer Set is not suitable for use with non-human species. Background: Histone 4 (H4) is one of the five core histone proteins, comprising the protein component of chromatin. H4 is ubiquitous within chromosomes and can be found bound to most gene sequences throughout the genome. Acetylation of lysine 5 on histone 4 (H4K5ac) is associated with open chromatin and active gene transcription. H4K5ac has been shown to have roles in epigenetic bookmarking, a process where genetic information is passed onto daughter cells during cell division. A rabbit IgG is included in this Antibody Primer Set as a negative control for the ChIP experiment. The H4K5ac positive primer set recognises the promoter of the GAPDH gene, associated with active transcription and is a suitable target for this antibody.

Function of Bromodomain and Extra-Terminal Motif Proteins (bets) in Gata1-Mediated Transcription Abstract Bromodomain and Extra-Terminal motif proteins (BETs) associate with acetylated histones and transcription factors. While pharmacologic inhibition of this ubiquitous protein family is an emerging therapeutic approach for neoplastic and inflammatory disease, the mechanisms through which BETs act remain largely uncharacterized. Here we explore the role of BETs in the physiologically relevant context of erythropoiesis driven by the transcription factor GATA1. First, we characterize functions of the BET family as a whole using a pharmacologic approach. We find that BETs are broadly required for GATA1-mediated transcriptional activation, but that repression is largely BET-independent. BETs support activation by facilitating both GATA1 occupancy and transcription downstream of its binding. Second, we test the specific olesr of BETs BRD2, BRD3, and BRD4 in GATA1-activated transcription. BRD2 and BRD4 are required for efficient anscriptionaltr activation by GATA1. Despite co-localizing with the great majority of GATA1 binding sites, we find that BRD3 is not equirr ed for GATA1-mediated transcriptional activation. -
A Stable Mode of Bookmarking by TBP Recruits RNA Polymerase II To
RESEARCH ARTICLE A stable mode of bookmarking by TBP recruits RNA polymerase II to mitotic chromosomes Sheila S Teves1*, Luye An2, Aarohi Bhargava-Shah1, Liangqi Xie1, Xavier Darzacq1, Robert Tjian1,3* 1Department of Molecular and Cell Biology, Li Ka Shing Center for Biomedical and Health Sciences, CIRM Center of Excellence, University of California, Berkeley, Berkeley, United States; 2Department of Biochemistry, Molecular and Cell Biology, Cornell University, Ithaca, United States; 3Howard Hughes Medical Institute, Berkeley, United States Abstract Maintenance of transcription programs is challenged during mitosis when chromatin becomes condensed and transcription is silenced. How do the daughter cells re-establish the original transcription program? Here, we report that the TATA-binding protein (TBP), a key component of the core transcriptional machinery, remains bound globally to active promoters in mouse embryonic stem cells during mitosis. Using live-cell single-molecule imaging, we observed that TBP mitotic binding is highly stable, with an average residence time of minutes, in stark contrast to typical TFs with residence times of seconds. To test the functional effect of mitotic TBP binding, we used a drug-inducible degron system and found that TBP promotes the association of RNA Polymerase II with mitotic chromosomes, and facilitates transcriptional reactivation following mitosis. These results suggest that the core transcriptional machinery promotes efficient transcription maintenance globally.

GABPA Is a Master Regulator of Luminal Identity and Restrains Aggressive Diseases in Bladder Cancer

This article is published with open access Abstract TERT promoter mutations occur in the majority of glioblastoma, bladder cancer (BC), and other malignancies while the ETS family transcription factors GABPA and its partner GABPB1 activate the mutant TERT promoter and telomerase in these tumors. GABPA depletion or the disruption of the GABPA/GABPB1 complex by knocking down GABPB1 was shown to inhibit telomerase, thereby eliminating the tumorigenic potential of glioblastoma cells. GABPA/B1 is thus suggested as a cancer therapeutic target. However, it is unclear about its role in BC. Here we unexpectedly observed that GABPA ablation 1234567890();,: 1234567890();,: inhibited TERT expression, but robustly increased proliferation, stem, and invasive phenotypes and cisplatin resistance in BC cells, while its overexpression exhibited opposite effects, and inhibited in vivo metastasizing in a xenograft transplant model. Mechanistically, GABPA directly activates the transcription of FoxA1 and GATA3, key transcription factors driving luminal differentiation of urothelial cells. Consistently, TCGA/GEO dataset analyses show that GABPA expression is correlated positively with luminal while negatively with basal signatures. -
Distinct Contributions of DNA Methylation and Histone Acetylation to the Genomic Occupancy of Transcription Factors
Downloaded from genome.cshlp.org on October 8, 2021 - Published by Cold Spring Harbor Laboratory Press Research Distinct contributions of DNA methylation and histone acetylation to the genomic occupancy of transcription factors Martin Cusack,1 Hamish W. King,2 Paolo Spingardi,1 Benedikt M. Kessler,3 Robert J. Klose,2 and Skirmantas Kriaucionis1 1Ludwig Institute for Cancer Research, University of Oxford, Oxford, OX3 7DQ, United Kingdom; 2Department of Biochemistry, University of Oxford, Oxford, OX1 3QU, United Kingdom; 3Target Discovery Institute, University of Oxford, Oxford, OX3 7FZ, United Kingdom Epigenetic modifications on chromatin play important roles in regulating gene expression. Although chromatin states are often governed by multilayered structure, how individual pathways contribute to gene expression remains poorly under- stood. For example, DNA methylation is known to regulate transcription factor binding but also to recruit methyl-CpG binding proteins that affect chromatin structure through the activity of histone deacetylase complexes (HDACs). Both of these mechanisms can potentially affect gene expression, but the importance of each, and whether these activities are inte- grated to achieve appropriate gene regulation, remains largely unknown. To address this important question, we measured gene expression, chromatin accessibility, and transcription factor occupancy in wild-type or DNA methylation-deficient mouse embryonic stem cells following HDAC inhibition. We observe widespread increases in chromatin accessibility at ret- rotransposons when HDACs are inhibited, and this is magnified when cells also lack DNA methylation. A subset of these elements has elevated binding of the YY1 and GABPA transcription factors and increased expression. The pronounced ad- ditive effect of HDAC inhibition in DNA methylation–deficient cells demonstrates that DNA methylation and histone deacetylation act largely independently to suppress transcription factor binding and gene expression. -

Email: [email protected] Abstract The ability of some transcription factors to remain bound to specific genes on condensed mitotic chromosomes has been suggested to play a role in their rapid transcriptional reactivation upon mitotic exit. We have recently shown that SOX2 and OCT4 remain associated to mitotic chromosomes, and that depletion of SOX2 at the mitosis-G1 (M-G1) transition impairs its ability to maintain pluripotency and drive neuroectodermal commitment. Here we report on the role of SOX2 at the M-G1 transition in regulating transcriptional activity of embryonic stem cells. -

Genome-Wide Analysis of H4K5 Acetylation Associated with Fear Memory in Mice C Sehwan Park1,3*, Hubert Rehrauer2 and Isabelle M Mansuy1,3
Park et al. BMC Genomics 2013, 14:539 http://www.biomedcentral.com/1471-2164/14/539 RESEARCH ARTICLE Open Access Genome-wide analysis of H4K5 acetylation associated with fear memory in mice C Sehwan Park1,3*, Hubert Rehrauer2 and Isabelle M Mansuy1,3 Abstract Background: Histone acetylation has been implicated in learning and memory in the brain, however, its function at the level of the genome and at individual genetic loci remains poorly investigated. This study examines a key acetylation mark, histone H4 lysine 5 acetylation (H4K5ac), genome-wide and its role in activity-dependent gene transcription in the adult mouse hippocampus following contextual fear conditioning. Results: Using ChIP-Seq, we identified 23,235 genes in which H4K5ac correlates with absolute gene expression in the hippocampus. However, in the absence of transcription factor binding sites 150 bp upstream of the transcription start site, genes were associated with higher H4K5ac and expression levels. We further establish H4K5ac as a ubiquitous modification across the genome. Approximately one-third of all genes have above average H4K5ac, of which ~15% are specific to memory formation and ~65% are co-acetylated for H4K12. Although H4K5ac is prevalent across the genome, enrichment of H4K5ac at specific regions in the promoter and coding region are associated with different levels of gene expression. Additionally, unbiased peak calling for genes differentially acetylated for H4K5ac identified 114 unique genes specific to fear memory, over half of which have not previously been associated with memory processes. Conclusions: Our data provide novel insights into potential mechanisms of gene priming and bookmarking by histone acetylation following hippocampal memory activation. -
