Defining the nitrogen regulated transcriptome of Mycobacterium smegmatis using continuous culture

Background: Nitrogen is essential for microbial growth and its importance is demonstrated by the complex regulatory systems used to control the transport, assimilation and metabolism of nitrogen. Recent studies are beginning to shed light on how mycobacter ...

A KAP1 phosphorylation switch controls MyoD function during skeletal muscle differentiation

Didier Trono, Evaristo Jose Planet Letschert, Marco Cassano, Suk Min Jang

The transcriptional activator MyoD serves as a master controller of myogenesis. Often in partnership with Mef2 (myocyte enhancer factor 2), MyoD binds to the promoters of hundreds of muscle genes in proliferating myoblasts yet activates these targets only ...

Molecular basis for the regulation of the nuclear receptor LRH-1

Kristina Schoonjans, Matthias Alexander Sokrates Stein

Liver receptor homolog-1 (LRH-1) is a nuclear receptor (NR) with diverse functions in development, differentiation and metabolism and has been extensively studied in the enterohepatic system. While initially described as an orphan NR, recent studies sugges ...

Visualizing the HoxD Gene Cluster at the Nanoscale Level

Denis Duboule, Suliana Manley, Aleksandr Benke, Pierre Raymond Fabre

Transcription of HoxD cluster genes in limbs is coordinated by two topologically associating domains (TADs), neighboring the cluster and containing various enhancers. Here, we use a combination of microscopy approaches and chromosome conformation capture t ...

The Crystal Structures of Apo and cAMP-Bound GlxR from Corynebacterium glutamicum Reveal Structural and Dynamic Changes upon cAMP Binding in CRP/FNR Family Transcription Factors

Stewart Cole, Florence Pojer

The cyclic AMP-dependent transcriptional regulator GlxR from Corynebacterium glutamicum is a member of the super-family of CRP/FNR (cyclic AMP receptor protein/fumarate and nitrate reduction regulator) transcriptional regulators that play central roles in ...

Modeling of transcription mechanisms in mammals from kinetic measurements in single cells

Benjamin Zoller

In mammals, transcription was observed to occur predominantly in bursts, resulting from short and intense periods of gene transcription interspersed by longer silent periods. In order to elucidate the causes and the consequences of discontinuous transcript ...

Assessing the role of Hes1 and identification of target genes in human and murine T-ALL

Silvia Wirth

The Notch signalling pathway is an ancient cell signalling mechanism that enables short-range communications between cells and controls a broad spectrum of cell fates and developmental processes. In the haematopoietic system Notch signalling has been linke ...

A potent and selective Sirtuin 1 inhibitor alleviates pathology in multiple animal and cell models of Huntington's disease

Ozgün Gökce, Davide Franceschini

Protein acetylation, which is central to transcriptional control as well as other cellular processes, is disrupted in Huntington's disease (HD). Treatments that restore global acetylation levels, such as inhibiting histone deacetylases (HDACs), are effecti ...

Two distinct promoter architectures centered on dynamic nucleosomes control ribosomal protein gene transcription

Felix Naef, Sebastian Maerkl, Jacques Rougemont, Nicolas Dénervaud, Marcel Geertz, Philippe Jacquet

In yeast, ribosome production is controlled transcriptionally by tight coregulation of the 138 ribosomal protein genes (RPGs). RPG promoters display limited sequence homology, and the molecular basis for their coregulation remains largely unknown. Here we ...

Rv2466c Mediates the Activation of TP053 To Kill Replicating and Non-replicating Mycobacterium tuberculosis

Stewart Cole, Ruben Hartkoorn, Anthony Vocat

The emergence of multidrug- and extensively drug-resistant strains of Mycobacterium tuberculosis highlights the need to discover new antitubercular agents. Here we describe the synthesis and characterization of a new series of thienopyrimidine (TP) compoun ...
