L'équipe Pintard a publié le 8 mars dernier un nouvel article dans eLife : Cortical microtubule pulling forces contribute to the union of the parental genomes in the Caenorhabditis elegans zygote   Abstract Previously, we reported that the Polo-like kinase PLK-1 phosphorylates the single Caenorhabditis elegans lamin (LMN-1) to trigger lamina depolymerization during mitosis. We showed that this event is required…

L'équipe Minc a publié le 15 février dernier un nouvel article dans PNAS : Contribution of cytoplasm viscoelastic properties to mitotic spindle positioning   Abstract Cells are filled with macromolecules and polymer networks that set scale-dependent viscous and elastic properties to the cytoplasm. Although the role of these parameters in molecular diffusion, reaction kinetics, and cellular biochemistry is…
