(Submitter supplied) The human Negative Elongation Factor (NELF) is a four-subunit protein complex that inhibits the movement of RNA polymerase II (RNAPII) at an early elongation stage in vitro. NELF-mediated stalling of RNAPII also attenuates transcription of a number of inducible genes in human cells. To obtain a genome-wide understanding of human NELF-mediated transcriptional regulation in vivo, we carried out an exon-array study in T47D breast cancer cells with transient siRNA knockdown of individual NELF subunits. more...

(Submitter supplied) In response to stress, human cells actively downregulate ongoing gene expression programs. Translational downregulation is accompanied by the assembly of stress granules which are cytosolic condensates containing ribosomes and mRNA. Transcriptional downregulation is caused by an increased recruitment of Negative Elongation Factors (NELF) to promoters, inhibiting RNA Pol II elongation. We report here that NELF forms nuclear condensates upon stress which can be recapitulated by liquid-liquid phase separation of recombinant NELF in vitro. more...

(Submitter supplied) To test whether Brd4 and SEC co-regulate the release of promoter-proximally paused Pol II, we performed Pol II ChIP-Seq to analyze the effect of depletion of Brd4 or SEC on HMBA-induced pause release in HCT116 cells.

(Submitter supplied) RNAPII pausing/termination shortly after initiation is a hallmark of gene regulation. However, the molecular mechanisms involved are still to be uncovered. Here, we show that NELF interacts with Integrator complex subunits (INTScom) forming a stable complex with RNPII and Spt5. The interaction between NELF and INTScom subunits is RNA and DNA independent. Using both HIV-1 promoter and genome wide analyses, we demonstrate that Integrator subunits specifically control NELF-mediated RNAPII pause/release at coding genes. more...

(Submitter supplied) Cdk9 is an essential transcriptional kinase that is conserved across distant eukaryotes, but we previously found that acute inhibition of Cdk9 causes different transcriptional phenotypes in NELF-containing higher eukaryotes (like mammals and Drosophila) vs. the NELF-lacking fission yeast S. pombe. NELF is known to participate in promoter-proximal pausing of RNA Polymerase II, and using NELF-depleted Drosophila cells,  we find that this NELF-mediated pause is necessary to prevent gene body entry by Pol II in the absence of Cdk9. more...

(Submitter supplied) Control of gene expression is one of the most complex yet continuous physiological processes impacting cellular homeostasis. RNA polymerase II (Pol II) transcription is tightly regulated at promoter-proximal regions by intricate dynamic processes including Pol II pausing, release into elongation, and premature termination. Here, we identify PTEN interacting with the Pol II transcription machinery and dephosphorylating Pol II C-terminal domain in vitro. more...

(Submitter supplied) Although the advances in genome-wide approaches have elucidated the functions of macrophage-specific distal regulatory elements in transcriptional responses, chromatin structures associated with PU.1 priming and the underlying mechanisms of action of these cis-acting sequences are not characterized. Here, we show that, in macrophages, FACT subunit SPT16 can bind to positioned nucleosomes directly flanking PU.1-bound sites at previously uncharacterized distal regulatory elements located near genes essential for macrophage development and functions. more...

(Submitter supplied) The Glucocorticoid Receptor (GR) potently represses macrophage-elicited inflammation, however, the underlying mechanisms remain obscure. Our genome-wide analysis reveals that pro-inflammatory paused genes, activated via global negative elongation factor (NELF) dissociation and RNA Polymerase (Pol)2 release from early elongation arrest, and non-paused genes, induced by de novo Pol2 recruitment, are equally susceptible to acute glucocorticoid repression. more...
