Tissue- and sex-specific small RNAomes reveal sex differences in response to the environment

Pierre Gönczy, Alexandra Bezler, Frédéric Schütz, Laurent Keller, Raffaella Conconi

RNA interference (RNAi) related pathways are essential for germline development and fertility in metazoa and can contribute to inter- and trans-generational inheritance. In the nematode Caenorhabditis elegans, environmental double-stranded RNA provided by ...

Single-molecule dynamics and genome-wide transcriptomics reveal that NF-kB (p65)-DNA binding times can be decoupled from transcriptional activation

Suliana Manley, Beat Fierz, David Michael Suter, Christian Sieben, Aleksandr Benke, Andrea Callegari

Transcription factors (TFs) regulate gene expression in both prokaryotes and eukaryotes by recognizing and binding to specific DNA promoter sequences. In higher eukaryotes, it remains unclear how the duration of TF binding to DNA relates to downstream tran ...

Exploring on Protein-DNA interactions

Alexandra Styliani Kalantzi

A variety of DNA-binding proteins organizes the chromosomal DNA and regulates gene transcription, and DNA replication and recombination. In particular, for gene regulation there is a category of DNA-binding proteins, the transcription factors, which can de ...

Promoter mutagenesis for fine-tuning expression of essential genes in Mycobacterium tuberculosis

Stewart Cole, Claudia Sala, Gaëlle Séraphine Kolly

A range of regulated gene expression systems has been developed for mycobacteria in the last few years to facilitate the study of essential genes, validate novel drug targets and evaluate their vulnerability. Among these, the TetR/Pip-OFF repressible promo ...

Characterization of the predicted membrane anchor of reductive dehalogenases

Julien Maillard, Lorenzo Cimmino, Marie Joanna Marie-Joseph Dannay

BACKGROUND Organohalide respiration (OHR) is a metabolic process that couples the reduction of halogenated organic compounds to energy conservation in a few phylogenetically diverse anaerobic bacteria. In this study, tetrachloroethene (= perchloroethene, P ...

Modeling and analysis of parts and devices of genetic regulation

Yves Berset

DNA encrypts the composition of the cellular material that is synthesized through transcription and translation. Never-theless, gene regulation mechanisms determine the final amount of transcribed and translated material. Transcription factors (TF) are a c ...

Hybrid proteins for the screening of transcription regulators of reductive dehalogenase gene clusters

Christof Holliger, Julien Maillard, Mathilde Stéphanie Willemin

In the past decade, research on the transcription regulation of reductive dehalogenase (rdh) gene clusters (for a recent review, see [1]) revealed a new set of CRP/FNR-type transcription regulators, called RdhK [2,3]. Several members of this family have be ...

Ecological strategies and metabolic trade-offs of complex environmental biofilms

Tom Ian Battin, Hannes Markus Peter

Microorganisms aggregated into matrix-enclosed biofilms dominate microbial life in most natural, engineered, and medical systems. Despite this, the ecological adaptations and metabolic trade-offs of the formation of complex biofilms are currently poorly un ...

What shapes eukaryotic transcriptional bursting?

Felix Naef, Damien Lionel Nicolas, Nicholas Edward Phillips

Isogenic cells in a common environment present a large degree of heterogeneity in gene expression. Part of this variability is attributed to transcriptional bursting: the stochastic activation and inactivation of promoters that leads to the discontinuous p ...

Batch Mode TD(lambda) for Controlling Partially Observable Gene Regulatory Networks

Utku Sirin

External control of gene regulatory networks (GRNs) has received much attention in recent years. The aim is to find a series of actions to apply to a gene regulation system making it avoid its diseased states. In this work, we propose a novel method for co ...
