L'équipe Ladoux/Mège a contribué à la publication d'un nouvel article dans The European Physical Journal E : Osmotic pressure induces unexpected relaxation of contractile 3D microtissue   Résumé : Cell contraction and proliferation, matrix secretion and external mechanical forces induce compression during embryogenesis and tumor growth, which in turn regulate cell proliferation, metabolism or differentiation. How compression affects…

L'équipe Minc a publié un nouvel article dans Current Biology : Cell division: Size-scaling cytoplasmic flows transport chromosomes to the right spot   Résumé : Early embryos undergo rounds of division, producing cells of reducing sizes that must scale the distance chromosomes segregate. A new study shows that this scaling results from a cell-size-dependent dampening of cytoplasmic flows…

L'équipe Minc a publié un nouvel article dans Journal of the royal society interface : Dynamic clamping induces rotation-to-beating transition of pinned filaments in gliding assays Résumé : We used numerical simulations to investigate how properties of motor proteins control the dynamical behaviour of driven flexible filaments. A filament on top of a patch of anchored motor proteins…

La plateforme ProtéoSeine a contribué à la publication d'un nouvel article dans Rapid Communications in Mass Spectometry : Electron Transfer Dissociation and Synchrotron UV Photodissociation of Trapped Sodiated Ions Produced From Polyacrylates by Electrospray Ionization   Résumé : Rationale Poly (acrylates)s can be distinguished from one another by the nature of their side chains. From model poly (acrylates)s, the…
