Functional Characterization of Nucleoid Associated Proteins Acting as Global Transcription Factors in Mycobacterium tuberculosis

Nina Theres Odermatt

The fatal lung disease tuberculosis is caused by the airborne Mycobacterium tuberculosis, a versatile pathogen adapted to rapidly changing environments. Instead of being eradicated by phagocytic cells of its human host, bacilli tune macrophages to support ...

On the statistical physics of chains and rods, with application to multi-scale sequence-dependent DNA modelling

Alexandre Emmanuel Grandchamp

The complex mechanisms involved in cellular processes have been increasingly understood this past century and the central role of the DNA molecule has been recognized. The base pair sequence along a DNA fragment is observed not only to encode the genomic i ...

Amongst the substances found in any living organism one of the most central in the workings of each living cell is deoxyribonucleic acid (DNA). For that reason it has been the subject of research in many of its aspects. These range from DNA sequencing to a ...

Significant cell-to-cell heterogeneity is ubiquitously observed in isogenic cell populations. Consequently, parameters of models of intracellular processes, usually fitted to population-averaged data, should rather be fitted to individual cells to obtain a ...

An Organometallic Compound which Exhibits a DNA Topology-Dependent One-Stranded Intercalation Mode

Paul Joseph Dyson, Ursula Röthlisberger, Giulia Palermo, Benjamin Samuel Murray, Thibaud Edouard Alistair von Erlach

Understanding how small molecules interact with DNA is essential since it underlies a multitude of pathological conditions and therapeutic interventions. Many different intercalator compounds have been studied because of their activity as mutagens or drugs ...

DNA adopts different conformations based on its environment. We reveal conditions that either preserve the DNA's physiological B-conformation, even upon its placement in UHV, or lead to a partial B-form to A-form reorganization upon DNA's deposition on a s ...

cgDNA: a software package for the prediction of sequence-dependent coarse-grain free energies of B-form DNA

John Maddocks, Daiva Petkeviciute, Marco Pasi

cgDNA is a package for the prediction of sequence-dependent configuration-space free energies for B-form DNA at the coarse-grain level of rigid bases. For a fragment of any given length and sequence, cgDNA calculates the configuration of the associated fre ...

We present the results of microsecond molecular dynamics simulations carried out by the ABC group of laboratories on a set of B-DNA oligomers containing the 136 distinct tetranucleotide base sequences. We demonstrate that the resulting trajectories have ex ...

Nuclear Factor I genomic binding associates with chromatin boundaries

Giovanni Dietler, Giovanna Ambrosini, Jan Kerschgens, Philipp Bucher, Nicolas Mermod, Petar Pjanic, Armelle Gaussin

Background: The Nuclear Factor I (NFI) family of DNA binding proteins (also called CCAAT box transcription factors or CTF) is involved in both DNA replication and gene expression regulation. Using chromatin immuno-precipitation and high throughput sequenci ...

Computational analysis of ultraconserved non-coding DNA elements in vertebrate genomes

Slavica Dimitrieva Janeva

Recent advancements in DNA sequencing technologies, accompanied by parallel development of sophisticated computational methods, offer an unprecedented opportunity to explore and study the genetic material of many organisms. However, despite the tremendous ...
