Nucleosome acidic patch-targeting binuclear ruthenium compounds induce aberrant chromatin condensation

Paul Joseph Dyson, Tina Riedel, Benjamin Samuel Murray

The 'acidic patch' is a highly electronegative cleft on the histone H2A-H2B dimer in the nucleosome. It is a fundamental motif for protein binding and chromatin dynamics, but the cellular impact of targeting this potentially therapeutic site with exogenous ...

In mammals the circadian clock drives daily behavioural and physiological changes that resonate with environmental cues, which can be observed, for example, in the intricate timing of rest during the night and activity during the day in humans. The circadi ...

Large scale genomic reorganization of topological domains at the HoxD locus

Denis Duboule, Marion Leleu, Lucille Delisle, Daniël Noordermeer, Pierre Raymond Fabre, Leonardo Beccari, Benjamin Howard Mormann

BACKGROUND: The transcriptional activation of HoxD genes during mammalian limb development involves dynamic interactions with two topologically associating domains (TADs) flanking the HoxD cluster. In particular, the activation of the most posterior HoxD g ...

The question of how self-interacting chromatin domains in interphase chromosomes are structured and generated dominates current discussions on eukaryotic chromosomes. Numerical simulations using standard polymer models have been helpful in testing the vali ...

Oxford University Press (OUP)2017

Hox gene clusters of jaw vertebrates display a tight genomic organization, which has no equivalent in any other bilateria genomes sequenced thus far. It was previously argued that such a topological consolidation toward a condensed, metagenic structure was ...

Chromatin organization, transcription factor dynamics and gene expression in higher eukaryotes with superresolution imaging and single molecule tracking

Aleksandr Benke

Gene expression is dynamic and heterogeneous across all cell types. It serves several fundamental functions such as adaptation for changing environment and developing tissue specific phenotype and functionality during development and in adult organism. Con ...

Chromatin condensation plays an important role in the regulation of gene expression. Recently, it was shown that the transcriptional activation of Hoxd genes during vertebrate digit development involves modifications in 3D interactions within and around th ...

Models that include supercoiling of topological domains reproduce several known features of interphase chromosomes

Julien Dorier, Yannis Burnier, Fabrizio Benedetti, Andrzej Stasiak

Understanding the structure of interphase chromosomes is essential to elucidate regulatory mechanisms of gene expression. During recent years, high-throughput DNA sequencing expanded the power of chromosome conformation capture (3C) methods that provide in ...

Oxford University Press2014

During development, a properly coordinated expression of Hox genes, within their different genomic clusters is critical for patterning the body plans of many animals with a bilateral symmetry. The fascinating correspondence between the topological organiza ...

Chromatin architectures and hox gene collinearity

Denis Duboule, Daniël Noordermeer

Ever since the observation that collinearity, that is, the sequential activity of Hox genes based on their relative positions within their gene clusters, is conserved throughout most of the animal kingdom, the question has been raised as to what are the un ...
