Gazave Lab – Transcriptomic landscape of posterior regeneration in the annelid Platynereis dumerilii

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…

Palancade Lab – A R-loop sensing pathway mediates the relocation of transcribed genes to nuclear pore complexes

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…

Ladoux /Mège Lab – Hexanematic crossover in epithelial monolayers depends on cell adhesion and cell density

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…

Conduit Lab & Guichet Lab – Multifaceted modes of γ-tubulin complex recruitment and microtubule nucleation at mitotic centrosomes

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,…

Azimzadeh Lab – Evolution: The ancient history of cilia assembly regulation

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.

IJM Seminar – Ben Montpetit – 12/10/2023

Invited by the Palancade Lab, Ben Montpetit (University of Californie, Davis, USA) will present an IJM seminar on the theme: RNA-binding protein (RBP) recruitment, occupancy, and stoichiometry in nuclear mRNA-protein complexes. Abstract: RNA-binding proteins (RBPs) interact with mRNA and associated factors to form supramolecular complexes called messenger ribonucleoprotein (mRNP) particles. These dynamic assemblies change to direct and…
