Séminaire IJM – Ben Montpetit – 12/10/2023

Invité par l'équipe Palancade, Ben Montpetit (Université de Californie, Davis, USA) présentera un séminaire IJM sur le thème : RNA-binding protein (RBP) recruitment, occupancy, and stoichiometry in nuclear mRNA-protein complexes. Résumé : 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…

Séminaire IJM – Joao Matos – 10/10/2023

Invité par l'équipe Wassmann, Joao Matos (Max Perutz Labs, University of Vienna) présentera un séminaire IJM sur le thème : Building, maintaining and discarding large macromolecular assemblies during gametogenesis The life cycle of sexually reproducing eukaryotes depends on two specialized chromosome segregation programs: mitosis and meiosis. Whereas mitosis drives cellular proliferation and the stable propagation of…

Séminaire IJM – Daniel J. Cohen – 25/09/2023

Invité par l'équipe Ladoux/Mège, Daniel J. Cohen (Princeton University) présentera un séminaire IJM sur le thème : ‘Chiens de berger’ cellulaires: understanding and controlling collective cell behaviors Collective cell behaviors are fundamental to the coordinated migration, proliferation, and decision-making of cells in a multicellular organism. Imagine if we could program these behaviors, effectively ‘herding’ cells to…

Séminaire IJM – Ivana Gasic – 11/07/2023

Invitée par Paul Conduit, Ivana Gasic présentera un séminaire IJM sur le thème : Autoregulated control of tubulin mRNA stability Abstract :  Microtubule cytoskeleton plays crucial roles in cellular architecture, intracellular transport, and mitosis. The availability of free tubulin subunits impacts polymerization dynamics and microtubule function. When cells sense excess free tubulin, they stop further tubulin biosynthesis…
