L'équipe Gazave a publié récemment dans Journal of Experimental Zoology part B: Molecular and developmental evolution : On the hormonal control of posterior regeneration in the annelid Platynereis dumerilii Résumé : Regeneration is the process by which many animals are able to restore lost or injured body parts. After amputation of the posterior part of its body, the annelid Platynereis…

L'équipe Camadro vient de publier dans Biochemistry and Molecular Biology Education : A field guide for implementing a flipped classroom Résumé : The way flipped classrooms are perceived and even practiced by teachers is sometimes approximate. For instance, while the Covid-19 pandemic has pushed many universities to adopt distance learning, flipped classrooms have often been mentioned as…

L'équipe Courtier vient de publier dans Biological reviews : Analysis of the genetic loci of pigment pattern evolution in vertebrates Vertebrate pigmentation patterns are amongst the best characterised model systems for studying the genetic basis of adaptive evolution. The wealth of available data on the genetic basis for pigmentation evolution allows for analysis of trends and…

L'équipe Guichet vient de publier dans Nature cell Biology : Basal stem cell progeny establish their apical surface in a junctional niche during turnover of an adult barrier epithelium Barrier epithelial organs face the constant challenge of sealing the interior body from the external environment while simultaneously replacing the cells that contact this environment. New replacement…

L'équipe Wassmann vient de publier dans le Med/Sci ( Paris) : Cyclin B3: Locking female meiosis to await fertilization  

L’équipe Romet-Lemonne/Jegou vient de publier un nouvel article dans the EMBO Journal. Regulation of branched versus linear Arp2/3-generated actin filaments Abstract Activation of the Arp2/3 complex by VCA-motif-bearing actin nucleation-promoting factors results in the formation of “daughter” actin filaments branching off the sides of pre-existing “mother” filaments. Alternatively, when stimulated by SPIN90, Arp2/3 directly nucleates “linear” actin…

L'équipe Greenberg vient de publier dans Genome Biology. Conservation and divergence of canonical and non-canonical imprinting in murids Abstract Background Genomic imprinting affects gene expression in a parent-of-origin manner and has a profound impact on complex traits including growth and behavior. While the rat is widely used to model human pathophysiology, few imprinted genes have been…

L'équipe Camadro (en collaboration avec ProteoSeine, Dumont Lab et Ladoux/Mège Lab) vient de publier un nouvel article dans Journal of Proteome Research : Extending the Range of SLIM-Labeling Applications: From Human Cell Lines in Culture to Caenorhabditis elegans Whole-Organism Labeling   Abstract The simple light isotope metabolic-labeling technique relies on the in vivo biosynthesis of amino acids from U-[12C]-labeled molecules…

L'équipe Minc vient de publier un nouvel article dans PNAS :   Size- and position-dependent cytoplasm viscoelasticity through hydrodynamic interactions with the cell surface   Abstract Many studies of cytoplasm rheology have focused on small components in the submicrometer scale. However, the cytoplasm also baths large organelles like nuclei, microtubule asters, or spindles that often take significant portions of…
