The Minc Lab published a new article in Journal of the royal society interface: Dynamic clamping induces rotation-to-beating transition of pinned filaments in gliding assays Abstract: 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 is…

The ProtéoSeine platform contributed to the publication of a new article published in Rapid Communications in Mass Spectometry: Electron Transfer Dissociation and Synchrotron UV Photodissociation of Trapped Sodiated Ions Produced From Polyacrylates by Electrospray Ionization   Abstract: Rationale Poly (acrylates)s can be distinguished from one another by the nature of their side chains. From model poly (acrylates)s, the…

The Ladoux/Mege Lab published a new article dans PNAS: Flocking and giant fluctuations in epithelial active solids   Significance During embryonic development and wound healing, epithelial cells usually display in-plane polarity over large spatial scales and move coherently. However, most in vitro studies have examined the fluid-like chaotic dynamics of epithelial cells, in which collective cellular flows…

The Wassmann Lab published a new article in Current Biology: Prolonged metaphase II arrest weakens Aurora B/C-dependent error correction in mouse oocytes   Abstract: Segregation errors in meiosis lead to aneuploid gametes and consequently to the development of trisomies, spontaneous abortion and fertility issues. Chromosome attachment to the microtubules of the bipolar spindle is a prerequisite for…

The Doye Lab contributed to the publication of a new article in Nature cell biology: Nuclear pores safeguard the integrity of the nuclear envelope   Abstract: Nuclear pore complexes (NPCs) mediate nucleocytoplasmic exchange, which is essential for eukaryotes. Mutations in the central scaffolding components of NPCs are associated with genetic diseases, but how they manifest only in specific…

The Ribes/Nedelec Lab contribued to the publication of a new article in Nature Communications: A differential requirement for ciliary transition zone proteins in human and mouse neural progenitor fate specification   Abstract: Studying ciliary genes in the context of the human central nervous system is crucial for understanding the underlying causes of neurodevelopmental ciliopathies. Here, we use pluripotent…

The Palancade contribued to the publication of a new article in Nature communications: A bifunctional snoRNA with separable activities in guiding rRNA 2’-O-methylation and scaffolding gametogenesis effectors Abstract: Small nucleolar RNAs are non-coding transcripts that guide chemical modifications of RNA substrates and modulate gene expression at the epigenetic and post-transcriptional levels. However, the extent of their…

The Romet-Lemonne / Jégou Lab contributed to the publication of a new article in Cell: Genetically encoded reporters of actin filament organization in living cells and tissues   Abstract: The cytoskeletal protein actin is crucial for cell shape and integrity throughout eukaryotes. Actin filaments perform essential biological functions, including muscle contraction, cell division, and tissue morphogenesis. These diverse…

The Ladoux/Mège published a new article in Nature material: Force transmission is a master regulator of mechanical cell competition Abstract: Cell competition is a tissue surveillance mechanism for eliminating unwanted cells, being indispensable in development, infection and tumourigenesis. Although studies have established the role of biochemical mechanisms in this process, due to challenges in measuring forces in…
