The Courtier Lab recently published a new article in Current Opinion in Insect Science : The loci of insect phenotypic evolution   Abstract: Insects are important elements of terrestrial ecosystems because they pollinate plants, destroy crops, transmit diseases to livestock and humans, and are important components of food chains. Here, I used Gephebase, a manually curated database of…

The Grange/Geigl Lab published a new article in Nature Ecology and Evolution :  Genome sequences of 36-37,000 year-old modern humans at Buran-Kaya III in Crimea Two 36 and 37,000-year-old genomes from Crimea shed light on the first successful implantations of modern Humans in Europe and on the emergence of the Gravettian culture The implantation of anatomically…

The Gazave Lab recently published a new article in BMC Genomics: Transcriptomic landscape of posterior regeneration in the annelid Platynereis dumerilii Abstract: Background Restorative regeneration, the capacity to reform a lost body part following amputation or injury, is an important and still poorly understood process in animals. Annelids, or segmented worms, show amazing regenerative capabilities, and as…

The Palancade Lab  recently published a new article in Nature  communications : A R-loop sensing pathway mediates the relocation of transcribed genes to nuclear pore complexes   Abstract: Nuclear pore complexes (NPCs) have increasingly recognized interactions with the genome, as exemplified in yeast, where they bind transcribed or damaged chromatin. By combining genome-wide approaches with live imaging…

The Ladoux/Mège recently contributed to the publication of an article in Nature Communications :  Hexanematic crossover in epithelial monolayers depends on cell adhesion and cell density Abstract: Changes in tissue geometry during developmental processes are associated with collective migration of cells. Recent experimental and numerical results suggest that these changes could leverage on the coexistence of nematic…

The Conduit Lab and the Guichet Lab recently published in Journal of Cell Biology : Multifaceted modes of γ-tubulin complex recruitment and microtubule nucleation at mitotic centrosomes Abstract: Microtubule nucleation is mediated by γ-tubulin ring complexes (γ-TuRCs). In most eukaryotes, a GCP4/5/4/6 “core” complex promotes γ-tubulin small complex (γ-TuSC) association to generate cytosolic γ-TuRCs. Unlike γ-TuSCs, however,…

The Azimzadeh Lab recently published in Current Biology : Evolution: The ancient history of cilia assembly regulation Abstract: A new study identifies a conserved regulatory mechanism for cilia assembly in the closest unicellular relatives of animals, suggesting that this mechanism was already present in a common unicellular ancestor and was repurposed during the transition to multicellularity.

The Doye Lab recently contributed to the publication of a new article in DNA Repair: Metazoan nuclear pore complexes in gene regulation and genome stability Abstract: The nuclear pore complexes (NPCs), one of the hallmarks of eukaryotic nuclei, allow selective transport of macromolecules between the cytoplasm and the nucleus. Besides this canonical function, an increasing number of additional roles have…

The Greenberg Lab contributed to the publication of a new article in Nucleic Acids Research: A genetic screen identifies BEND3 as a regulator of bivalent gene expression and global DNA methylation   Abstract:  Epigenetic mechanisms are essential to establish and safeguard cellular identities in mammals. They dynamically regulate the expression of genes, transposable elements and higher-order chromatin structures. Consequently,…

The Prioleau Lab contributed to the publication of a new article in Nature communications : Histone H3 serine-57 is a CHK1 substrate whose phosphorylation affects DNA repair Abstract: Histone post-translational modifications promote a chromatin environment that controls transcription, DNA replication and repair, but surprisingly few phosphorylations have been documented. We report the discovery of histone H3 serine-57…
