(Submitter supplied) Transcriptional elongation by RNA polymerase II (Pol II) is regulated by positive transcription elongation factor b (P-TEFb) in association with Bromodomain-containing protein 4 (BRD4). We used genome-wide chromatin immunoprecipitation sequencing in primary human CD4+ T cells to reveal that BRD4 co-localizes with Ser2-phosphorylated Pol II (Pol II Ser2) at both enhancers and promoters of active genes. more...

(Submitter supplied) In serum-starved and re-fed mouse fibroblast, nascent RNA-seq analysis showed that the BET inhibitor JQ1 antagonized a process regulating PIC formation and a downstream process involved in progressive elongation. To specifically address the role of BRD4 and its interactions with acetylated histones and P-TEFb, YFP-tagged BRD4 proteins (wild type and mutant BRD4) were stably expressed in cells, endogenous BRD4 of which was knocked down by shRNA (shBRD4). more...

(Submitter supplied) To study the role of the bromodomain (BD) in BRD4-dependent gene expression, we compared the function of wild type BRD4 and a mutant BRD4-mBD, which carries a point mutation in each of the two BDs. We first knocked down endogenous BRD4 by shRNA (shBRD4) and then stably reconstituted the cells with shBRD4-resistant YFP-BRD4 (wild type or mBD mutant). Following BRD4 reconstitution, the degree of recovery in gene expression was analyzed by Affymetrix Mouse Exon 1.0 ST array. more...

(Submitter supplied) To explore the global mechanisms of estrogen-regulated transcription, we used chromatin immunoprecipitation coupled with DNA microarrays to determine the localization of RNA polymerase II (Pol II), estrogen receptor alpha (ERalpha), steroid receptor coactivator proteins (SRC), and acetylated histones H3/H4 (AcH) at estrogen-regulated promoters in MCF-7 cells with or without estradiol (E2) treatment. more...

(Submitter supplied) Hormone-dependent gene expression requires dynamic and coordinated epigenetic changes. Estrogen receptor-positive (ER+) breast cancer is particularly dependent upon extensive chromatin remodeling and changes in histone modifications for the induction of hormone-responsive gene expression. Our previous studies established an important role of bromodomain-containing protein-4 (BRD4) in promoting estrogen-regulated transcription and proliferation of ER+ breast cancer cells. more...

(Submitter supplied) Purpose: BRD4 is a chromatin reader and transcriptional activator of M/G1 genes.We discovered that BRD4 is a novel histone acetyltransferase that acetylates histones and evicts nucleosomes. Here, investigated genome-wide changes in nucleosome occupancy and transcription caused by BRD4 HAT activity . Method: Human U2OS cells were transfected with either wild type BRD4 (WT), a BRD4 HAT mutant (MT) or a empty vector (NT) in biological duplicates, harvested 18 hrs post transfection and subjected to global MNase-seq and RNA-seq analysis. more...

(Submitter supplied) We identified a chromatin displacement signature for the bromodomain proteins BRD2, BRD3 and BRD4 at TSS following treatment with I-BET152, an inhibitor of BET proteins. By integrating ChIP-seq, RNA-seq and Chem-seq data, we correlated alteration of the BRD4 signature at TSS with strong downregulation of gene expression which will facilitate identification of markers of sensitivity and resistance to drug.

Transcription factors and chromatin remodeling complexes are key determinants of embryonic stem cell (ESC) identity.

(Submitter supplied) Distal enhancers characterized by H3K4me1 mark play critical roles in developmental and transcriptional programs. However, potential roles of specific distal regulatory elements in regulating RNA Polymerase II (Pol II) promoter-proximal pause release remain poorly investigated. Here we report that a unique cohort of jumonji C domain-containing protein 6 (JMJD6) and bromodomain-containing protein 4 (Brd4) co-bound distal enhancers, termed anti-pause enhancers (A-PEs), regulate promoter-proximal pause release of a large subset of transcription units via long-range interactions. more...

(Submitter supplied) This SuperSeries is composed of the SubSeries listed below. Reactivation of the pluripotency network during somatic cell reprogramming by exogenous transcription factors involves chromatin remodeling and the recruitment of RNA polymerase II (Pol II) to target loci. Here, we report that Pol II is engaged at pluripotency promoters in reprogramming but remains paused and inefficiently released. We also show that bromodomain-containing protein 4 (BRD4) stimulates productive transcriptional elongation of pluripotency genes by dissociating the pause release factor P-TEFb from an inactive complex containing HEXIM1. more...
