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 Abstract : 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 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,…
