La plateforme ProtéoSeine a contribué à la publication d'un nouvel article dans Molecular Cell : Cell-cycle-dependent mRNA localization in P-bodies   Résumé : Understanding the dynamics of RNA targeting to membraneless organelles is essential to disentangle their functions. Here, we investigate how P-bodies (PBs) evolve during cell-cycle progression in HEK293 cells. PB purification across the cell cycle…

L'équipe Courtier a publié un nouvel article dans Scientific Reports : Adhesive and mechanical properties of the glue produced by 25 Drosophila species   Résumé : Drosophila glue, a bioadhesive produced by fly larvae to attach themselves to a substrate for several days, has recently gained attention for its peculiar adhesive and mechanical properties. Although Drosophila glue production was described more than 50 years…

L'équipe Dumont a publié un nouvel article dans Current Biology : Regulation of outer kinetochore assembly during meiosis I and II by CENP-A and KNL-2/M18BP1 in C. elegans oocytes   Résumé : During cell division, chromosomes build kinetochores that attach to spindle microtubules. Kinetochores usually form at the centromeres, which contain CENP-A nucleosomes. The outer kinetochore, which is the core…

L'équipe Pintard a contribué à la publication d'un nouvel article dans Nucleic Acids Research : Enhanced Golden Gate Assembly: evaluating overhang strength for improved ligation efficiency   Résumé : Molecular cloning, a routine yet essential technique, relies heavily on efficient ligation, which can be significantly improved using Golden Gate Assembly (GGA). A key component of GGA is the use…

L'équipe Gazave a publié un nouvel article dans Genome Biology and Evolution : Evolution of apoptotic signalling pathways within lophotrochozoans   Résumé : Apoptosis is the main form of regulated cell death in metazoans. Apoptotic pathways are well characterised in nematode, fly and mammals, leading to a vision of the conservation of apoptotic pathways in metazoans. However, we…

Un rôle des microtubules astraux dans l’orientation de la division cellulaire - Quand la longueur compte… aussi ! [A role…

L'équipe Greenberg a publié un nouvel article dans Nucleic Acids Research : The impact of the embryonic DNA methylation program on CTCF-mediated genome regulation   Résumé : During mammalian embryogenesis, both the 5-cytosine DNA methylation (5meC) landscape and three dimensional (3D) chromatin architecture are profoundly remodeled during a process known as ‘epigenetic reprogramming.’ An understudied aspect of epigenetic…

L'équipe Grange/Geigl a contribué à la publication d'un nouvel article dans Annals of Rheumatic Diseases : SerpinA3N limits cartilage destruction in osteoarthritis by inhibiting macrophage-derived leucocyte elastase   Résumé : Objectives Inflammatory mediators such as interleukin 6 (IL-6) are known to activate catabolic responses in chondrocytes during osteoarthritis (OA). This study aimed to investigate the role of a downstream…
