L'équipe Ladoux/Mege a publié une nouvelle review dans Trends in Cell Biology : Biophysical principles of cell competition and elimination Highlights Cells within heterogeneous tissues can use forces to outcompete and eliminate cells of lower mechanical fitness through various strategies. Cellular biophysical properties, such as cell–cell or cell–substrate adhesion, force generation and transmission, contractility, and stiffness, can provide…

La plateforme ProtéoSeine a contribué à la publication d'un nouvel article dans Nature Communications : Greatwall depletion from Xenopus oocytes reveals a key role of the cyclin B/CDK1-PP2A-B55 balance in the coordination of meiotic events Résumé : Meiotic progression relies on maintaining a precise balance between cyclin B/CDK1 activity and the phosphatase PP2A-B55. The latter is…

La plateforme ProtéoSeine a contribué à la publication d'un nouvel article dans Cell Death & Disease : EMILIN1 emerges as a TGFβ/SETDB1-regulated secreted biomarker in Duchenne muscular dystrophy Résumé : Duchenne muscular dystrophy (DMD) is an incurable muscle-wasting disorder characterized by chronic membrane damage, inflammation, and progressive fibrosis. Fibrosis in DMD is driven by sustained TGFβ…

L'équipe Jackson/Verbavatz a contribué à un nouvel article publié dans Journal of Microscopy : Stress and conflict management in core facilities - News from an imaging survey Résumé : While conflict management is a well-known challenge for people working in the service sector, this topic remains largely unexplored in scientific imaging core facilities, despite frequent interactions with…

L'équipe Duharcourt a publié un nouvel article dans Nucleic Acids Research : A developmental condensin I complex assists the Paramecium PiggyMac domesticated transposase during programmed DNA elimination Résumé : Prokaryotes and eukaryotes use diverse strategies to cope with invading mobile genetic elements, including programmed DNA elimination (PDE). In the ciliate Paramecium, elimination of transposable elements and their relics requires the…

L'équipe Ladoux/Mege a publié un nouvel article dans Science Advances : Dynamic heterogeneity and hidden fluidity in dense epithelial tissues Résumé : Epithelial tissues maintain organ integrity while continuously remodeling during morphogenesis, repair, and disease. At high cell densities, these tissues often appear mechanically arrested in a disordered, solid-like state, raising the question of how they retain…

The chromosomal origin of replication as the basis for the spatio-temporal biology of bacteria Résumé : Spatial biology depends on the structural dynamics of the constituents of the cell. We propose that such dynamics during the cell cycle depend to a large extent on the origin of replication and its role in the trajectory of a…

L'ancienne équipe Camadro a contribué à la publication d'un nouvel article dans The ISME Journal : Iron limitation promotes metabolic cross-feeding between cheese ripening bacteria Résumé : Iron is a limiting micronutrient in various environments, and its scarcity orchestrates microbial interactions across diverse ecosystems. The cheese surface, which is oxic, iron-limited, and a host of moderately complex…

L'équipe Guichet a contribué à la publication d'un chapitre de livre: Sexual Development in Fungi Résumé : This chapter explores the genetic and cellular mechanisms governing sexual reproduction in fungi, with a focus on Ascomycota and Basidiomycota. Sexual reproduction is orchestrated by the genetic regulation of mating identity, which ensures the recognition and differentiation of compatible partners.…

L'équipe Dumont a publié un nouvel article dans médecine / science : The interkinetic envelope: a discovery that challenges our knowledge of oocyte meiosis   El Mossadeq L, Dumont J. L’enveloppe d’intercinèse - Une découverte qui bouscule notre connaissance de la méiose ovocytaire [The interkinetic envelope: a discovery that challenges our knowledge of oocyte meiosis]. Med Sci…
