L'équipe Courtier a récemment publié un nouvel article dans BMC Ecology and Evolution : Higher evolutionary dynamics of gene copy number for Drosophila glue genes located near short repeat sequences Résumé : Background During evolution, genes can experience duplications, losses, inversions and gene conversions. Why certain genes are more dynamic than others is poorly understood.…

L'équipe Wassmann a publié un nouvel article dans EMBO : Qualitative rather than quantitative phosphoregulation shapes the end of meiosis I in budding yeast   Résumé : Exit from mitosis is brought about by dramatic changes in the phosphoproteome landscape. A drop in Cyclin-dependent kinase (Cdk) activity, the master regulatory kinase, and activation of counteracting phosphatases such as Cdc14…

L'équipe Romet-Lemonne/Jégou a contribué à la publication d'un nouvel article dans Nature structural & molecular biology : Cortactin stabilizes actin branches by bridging activated Arp2/3 to its nucleated actin filament   Résumé : Regulation of the assembly and turnover of branched actin filament networks nucleated by the Arp2/3 complex is essential during many cellular processes, including cell migration…

L'équipe Guichet a publié un nouvel article dans Cells : The Importance of the Position of the Nucleus in Drosophila  Oocyte Development Résumé : Oogenesis is a developmental process leading to the formation of an oocyte, a haploid gamete, which upon fertilisation and sperm entry allows the male and the female pronuclei to fuse and give rise to…

L'équipe Romet-Lemonne/Jégou a publié un nouvel article dans Science Advances : Regeneration of actin filament branches from the same Arp2/3 complex Résumé : Branched actin filaments are found in many key cellular structures. Branches are nucleated by the Arp2/3 complex activated by nucleation-promoting factor (NPF) proteins and bound to the side of preexisting “mother” filaments. Over time,…

L'équipe Palancade a publié une nouvelle review dans Current Opinion in Genetics & Development : On the edge: how nuclear pore complexes rule genome stability   Résumé : Nuclear organization has emerged as a critical layer in the coordination of DNA repair activities. Distinct types of DNA lesions have notably been shown to relocate at the vicinity…

L'équipe Greenberg a contribué à la publication d'un nouvel article dans Nature Structural & Molecular biology : DNA methylation restricts coordinated germline and neural fates in embryonic stem cell differentiation   Résumé : As embryonic stem cells (ESCs) transition from naive to primed pluripotency during early mammalian development, they acquire high DNA methylation levels. During this transition, the…

L'équipe Camadro et la plateforme ProtéoSeine ont contribué à la publication d'un nouvel article dans eBioMedicine : Multiomic analysis in fibroblasts of patients with inborn errors of cobalamin metabolism reveals concordance with clinical and metabolic variability   Résumé : Background The high variability in clinical and metabolic presentations of inborn errors of cobalamin (cbl) metabolism (IECM), such as the cblC/epicblC types…

L'équipe Raote a contribué à la publication d'un nouvel article dans PNAS : A model for collagen secretion by intercompartmental continuities   Résumé : Newly synthesized secretory proteins are exported from the endoplasmic reticulum (ER) at specialized subcompartments called exit sites (ERES). Cargoes like procollagen are too large for export by the standard COPII-coated vesicle of 60 nm…

L'équipe Balavoine a récemment publié un nouvel article dans Plos One : Fast cycling culture of the annelid model Platynereis dumerilii   Résumé : Platynereis dumerilii, a marine annelid, is a model animal that has gained popularity in various fields such as developmental biology, biological rhythms, nervous system organization and physiology, behaviour, reproductive biology, and epigenetic regulation. The…
