L'équipe Ladoux/Mege a contribué à la publication d'un nouvel article dans Nature Communications : A multicellular star-shaped actin network underpins epithelial organization and connectivity Résumé : Epithelial tissues withstand external stresses while maintaining structural stability. Bicellular junctions and the actomyosin network support epithelial integrity, packing and remodelling. While their role in development and disease are well studied,…

La plateforme ProtéoSeine a contribué à la publication d'un nouvel article dans Journal of biological chemistry: Structural and functional characterization of CREB-binding protein (CREBBP) as a histone propionyltransferase Résumé : In addition to histone acetylation, histone lysine propionylation (such as the H3K18Pr mark) has recently attracted significant attention as a common and abundant modification linking the cellular…

L'équipe Palancade et la plateforme ProtéoSeine ont contribué à la publication d'un nouvel article dans PLOS genetics : Cellular imbalance of specific RNA binding proteins associates with harmful R-loops Résumé : Understanding how the assembly of nascent mRNA into a ribonucleoprotein (mRNP) influences R-loop homeostasis is crucial for gaining insight into the cellular mechanisms that prevent genome…

L'équipe Courtier a publié un nouvel article dans Development : Evolution of a novel left-right asymmetry in organ size by co-option of a tissue rotation process Résumé : Left-right asymmetries have repeatedly evolved in diverse animals and affect the position, shape or size of specific organs. How novel left-right asymmetries arise remains unknown. Here, we examined Drosophila pachea,…

L'équipe Raote a contribué à la publication d'un nouvel article dans Nature communications : TUG protein acts through a disordered region to organize the early secretory pathway Résumé : The Endoplasmic Reticulum (ER)-Golgi Intermediate Compartment (ERGIC) is a network of tubules and vesicles known for producing COPI vesicles and receiving COPII vesicles from the ER. Much about…

L'équipe Guichet a contribué à une nouvelle publication dans Journal of Evolutionary Biology : Sheltered load in fungal mating-type chromosomes revealed by fitness experiments Résumé : Sex chromosomes and mating-type chromosomes can carry large regions with suppressed recombination. As a result of a lower efficacy of selection, recessive deleterious mutations are expected to accumulate in these non-recombining…

L'équipe Greenberg a contribué à la publication d'un nouvel article dans Epigenetics : PIK3R1 and G0S2 are human placenta-specific imprinted genes associated with germline-inherited maternal DNA methylation   Résumé : Genomic imprinting is the parent-of-origin specific monoallelic expression of genes that result from complex epigenetic interactions. It is often achieved by monoallelic 5-methylcytosine, resulting in the formation of differentially methylated regions…

L'équipe Ladoux-Mège a publié un nouvel article dans Biophysical Journal : The enteric nervous system is 10 times stiffer than the brain Résumé : Neural tissues of the central nervous system are among the softest and most fragile in the human body, protected from mechanical perturbation by the skull and the spine. In contrast, the enteric nervous…

L'équipe Romet-Lemonne/Jégou a publié une nouvelle publication dans PNAS : Continuous self-repair protects vimentin intermediate filaments from fragmentation Résumé : Intermediate filaments are key regulators of cell mechanics. Vimentin, a type of intermediate filament expressed in mesenchymal cells and involved in migration, forms a dense network in the cytoplasm that is constantly remodeling through filament transport, elongation/shortening,…
