Sumoylated Human Histone H4 Prevents Chromatin Compaction by Inhibiting Long-range Internucleosomal Interactions

The structure of eukaryotic chromatin directly influences gene function, and is regulated by chemical modifications of the core histone proteins. Modification of the human histone H4 N-terminal tail region by the small ubiquitin-like modifier protein, SUMO ...

Multiscale Spatial Organization of RNA Polymerase in Escherichia coli

Seamus John Holden

Nucleic acid synthesis is spatially organized in many organisms. In bacteria, however, the spatial distribution of transcription remains obscure, owing largely to the diffraction limit of conventional light microscopy (200-300 nm). Here, we use photoactiva ...

Detection of RNAP-DNA complexes using solid state nanopores

Aleksandra Radenovic, Michael Graf, Camille Alice Raillon

Transcription is the first step in gene expression where DNA is copied into RNA. It is extensively studied at the bulk level especially the regulation mechanism, which in cancerous cells is impaired. We were interested in studying E. coli RNAP enzyme at th ...

High-resolution transcriptome and genome-wide dynamics of RNA polymerase and NusA in Mycobacterium tuberculosis

Stewart Cole, Jacques Rougemont, Claudia Sala, Swapna Uplekar

To construct a regulatory map of the genome of the human pathogen, Mycobacterium tuberculosis, we applied two complementary high-resolution approaches: strand-specific RNA-seq, to survey the global transcriptome, and ChIP-seq, to monitor the genome-wide dy ...

A KRAB/KAP1-miRNA Cascade Regulates Erythropoiesis Through Stage-Specific Control of Mitophagy

Didier Trono, Jiri Vanicek, Isabelle Barde, Sonia Verp, Sandra Eloise Kjeldsen, Adamantia Kapopoulou, Andrea Corsinotti, Ray Marcel Marin Florez, Benjamin Rauwel

During hematopoiesis, lineage- and stage-specific transcription factors work in concert with chromatin modifiers to direct the differentiation of all blood cells. Here, we explored the role of KRAB-containing zinc finger proteins (KRAB-ZFPs) and their cofa ...

Genomic Study of RNA Polymerase II and III SNAPc-Bound Promoters Reveals a Gene Transcribed by Both Enzymes and a Broad Use of Common Activators

David Paul Roger Romascano, Nouria Hernandez

SNAP(c) is one of a few basal transcription factors used by both RNA polymerase (pol) II and pol III. To define the set of active SNAP(c)-dependent promoters in human cells, we have localized genome-wide four SNAP(c) subunits, GTF2B (TFIIB), BRF2, pol II, ...

Nanopore sensing of single molecules application to RNAP-DNA complexes, fabrication of graphene-nanopore devices and translocation algorithm analysis

Camille Alice Raillon

Nanopore sensing is a single-molecule technique that allows to probe the nano-bio-world with accuracy. It is a non-invasive technique, which means that the molecule of interest does not need to be labeled to be detected by the nanopore. Most of the studies ...

Genome-Wide RNA Polymerase II Profiles and RNA Accumulation Reveal Kinetics of Transcription and Associated Epigenetic Changes During Diurnal Cycles

Olivier Martin, Bart Deplancke, Felix Naef, Jacques Rougemont, Nicolas Jean Philippe Guex, Winship Herr, Mauro Delorenzi, Nouria Hernandez, Laura Symul

Interactions of cell-autonomous circadian oscillators with diurnal cycles govern the temporal compartmentalization of cell physiology in mammals. To understand the transcriptional and epigenetic basis of diurnal rhythms in mouse liver genome-wide, we gener ...

Genome-wide mapping of Myc binding and gene regulation in serum-stimulated fibroblasts

The transition from quiescence to proliferation is a key regulatory step that can be induced by serum stimulation in cultured fibroblasts. The transcription factor Myc is directly induced by serum mitogens and drives a secondary gene expression program tha ...

Telomeric Repeat Containing RNAs and the Response to Telomere Deprotection in Saccharomyces Cerevisiae

Andrea Bernardo Panza

Telomeres are the DNA/RNA/protein structures at the end of linear eukaryotic chromosomes, which protect them against the DNA damage repair machinery, preventing chromosome end-to-end fusions and aberrant recombination. Moreover, telomeres compensate for th ...
