Composition of the DNA-uptake complex of Vibrio cholerae

Melanie Blokesch, Lisa Christina Metzger

Natural competence for transformation is a developmental program that allows certain bacteria to take up free extracellular DNA from the environment and integrate this DNA into their genome. Thereby, natural transformation acts as mode of horizontal gene t ...

Identification of the transcription factor ZEB1 as a central component of the adipogenic gene regulatory network

Didier Trono, Andrea Corsinotti, Bart Deplancke, Sebastian Martin Waszak, Sunil Kumar Raghav, Petra Catalina Schwalie, Gilles Udin

Adipose tissue is a key determinant of whole body metabolism and energy homeostasis. Unraveling the regulatory mechanisms underlying adipogenesis is therefore highly relevant from a biomedical perspective. Our current understanding of fat cell differentiat ...

Bile Acids Alter Male Fertility Through G-Protein-Coupled Bile Acid Receptor 1 Signaling Pathways in Mice

Kristina Schoonjans

Bile acids (BAs) are signaling molecules that are involved in many physiological functions, such as glucose and energy metabolism. These effects are mediated through activation of the nuclear and membrane receptors, farnesoid X receptor (FXR-alpha) and TGR ...

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

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

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 ...

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

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

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 ...

Systematic Analysis of Yeast Gene Expression by Synthetic Promoter Libraries

Arun Stephen Rajkumar

The precise tuning of gene expression levels is essential for optimal performance of transcriptional regulatory networks. Many regulatory components control promoter output, but transcription factor (TF) binding sites are amongst the most prominent. Beside ...

iSLIM: a comprehensive approach to mapping and characterizing gene regulatory networks

Bart Deplancke, Sebastian Maerkl, Marcel Geertz, Sylvie Rockel

Mapping gene regulatory networks is a significant challenge in systems biology, yet only a few methods are currently capable of systems-level identification of transcription factors (TFs) that bind a specific regulatory element. We developed a microfluidic ...

MAR-mediated integration of plasmid vectors for in vivo gene transfer and regulation

Andrzej Kulik, Nicolas Mermod, Stefania Puttini, Déborah Ley, Damien Saugy

Background: The in vivo transfer of naked plasmid DNA into organs such as muscles is commonly used to assess the expression of prophylactic or therapeutic genes in animal disease models. Results: In this study, we devised vectors allowing a tight regulatio ...

HDAC4 Reduction: A Novel Therapeutic Strategy to Target Cytoplasmic Huntingtin and Ameliorate Neurodegeneration

Histone deacetylase (HDAC) 4 is a transcriptional repressor that contains a glutamine-rich domain. We hypothesised that it may be involved in the molecular pathogenesis of Huntington's disease (HD), a protein-folding neurodegenerative disorder caused by an ...

Development and application of experimental tools to elucidate the gene regulatory network underlying adipogenesis

Carine Delattre-Gubelmann

Excess fat mass in obese individuals, which is characterized by an increase of white adipocyte cell size and number, significantly raises the risk of developing metabolic syndrome symptoms as well as cancer. A detailed understanding of the transcriptional ...
