Inheritance of H3K9 methylation regulates genome architecture in Drosophila early embryos

Constitutive heterochromatin is essential for transcriptional silencing and genome integrity. The establishment of constitutive heterochromatin in early embryos and its role in early fruitfly development are unknown. Lysine 9 trimethylation of histone H3 ( ...

Wide-scale identification of novel/eliminated genes responsible for evolutionary transformations

Daria Korotkova

BackgroundIt is generally accepted that most evolutionary transformations at the phenotype level are associated either with rearrangements of genomic regulatory elements, which control the activity of gene networks, or with changes in the amino acid conten ...

Puckered and JNK signaling in pioneer neurons coordinates the motor activity of the Drosophila embryo

Samuel William Vernon

Central nervous system organogenesis is a complex process that obeys precise architectural rules. The impact that nervous system architecture may have on its functionality remains, however, relatively unexplored. To clarify this problem, we analyze the dev ...

Sequential in cis mutagenesis in vivo reveals various functions for CTCF sites at the mouse HoxD cluster

Denis Duboule, Lucille Delisle, Jozsef Zakany, Leonardo Beccari

In this study, Amandio et al. sought to understand the functions of the highly conserved CTCF sites distributed over the Hox gene clusters. The authors produced an allelic series of cumulative in cis mutations in these sites, up to the abrogation of CTCF b ...

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 ...

Sequential pattern formation governed by signaling gradients

Andrew Charles Oates

Rhythmic and sequential segmentation of the embryonic body plan is a vital developmental patterning process in all vertebrate species. However, a theoretical framework capturing the emergence of dynamic patterns of gene expression from the interplay of cel ...

The Developmental Control of Transposable Elements and the Evolution of Higher Species

Didier Trono, Marc Samuel Friedli

Transposable elements (TEs) account for at least 50% of the human genome. They constitute essential motors of evolution through their ability to modify genomic architecture, mutate genes and regulate gene expression. Accordingly, TEs are subject to tight e ...

Context-dependent transcriptional interpretation of mitogen activated protein kinase signaling in the Drosophila embryo

Bart Deplancke, Antonina Iagovitina

Terminal regions of the Drosophila embryo are patterned by the localized activation of Mitogen Activated Protein Kinase (MAPK), which induces zygotic genes through relief of their repression by transcriptional repressor Capicua. The levels of MAPK activati ...

A red/far-red light-responsive bi-stable toggle switch to control gene expression in mammalian cells

Stéphanie Elisabeth Metzger, Martin Ehrbar

Growth and differentiation of multicellular systems is orchestrated by spatially restricted gene expression programs in specialized subpopulations. The targeted manipulation of such processes by synthetic tools with high-spatiotemporal resolution could, th ...

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 ...
