L'équipe Duharcourt a publié une nouvelle revue dans WIREs RNA : Small-RNA-guided histone modifications and somatic genome elimination in ciliates   Résumé : Transposable elements and other repeats are repressed by small-RNA-guided histone modifications in fungi, plants and animals. The specificity of silencing is achieved through base-pairing of small RNAs corresponding to the these genomic loci to nascent…

L'équipe Conduit a publié un nouvel article dans Journal of Cell Science : γ-TuRCs and Augmin are required for the development of highly branched dendritic arbors in Drosophila   Résumé : Microtubules are nucleated by γ-tubulin ring complexes (γ-TuRCs) and are essential for neuronal development. Nevertheless, γ-TuRC depletion has been reported to perturb only higher-order branching in elaborated Drosophila larval…

L'équipe Palancade a contribué à la publication d'un nouvel article dans Nature communications : Accelerated DNA replication fork speed due to loss of R-loops in myelodysplastic syndromes with SF3B1 mutation Résumé : Myelodysplastic syndromes (MDS) with mutated SF3B1 gene present features including a favourable outcome distinct from MDS with mutations in other splicing factor genes SRSF2 or U2AF1. Molecular bases of these…

L'équipe Greenberg a publié un nouvel article dans Nature structural & molecular biology : The impact of DNA methylation on CTCF-mediated 3D genome organization Résumé Cytosine DNA methylation is a highly conserved epigenetic mark in eukaryotes. Although the role of DNA methylation at gene promoters and repetitive elements has been extensively studied, the function of…

Les plateformes ProtéoSeine et ImagoSeine ont contribué à la publication d'un article dans Nature communications : Theileria parasites sequester host eIF5A to escape elimination by host-mediated autophagy Résumé Intracellular pathogens develop elaborate mechanisms to survive within the hostile environments of host cells. Theileria parasites infect bovine leukocytes and cause devastating diseases in cattle in developing countries. Theileria spp. have evolved…

L'équipe Gazave a publié un nouvel article dans Scientific report : Extrinsic apoptosis participates to tail regression during the metamorphosis of the chordate Ciona Résumé Apoptosis is a regulated cell death ubiquitous in animals defined by morphological features depending on caspases. Two regulation pathways are described, currently named the intrinsic and the extrinsic apoptosis. While intrinsic apoptosis…

L'équipe Jackson/Verbavatz a publié un nouvel article dans eLife : The ER tether VAPA is required for proper cell motility and anchors ER-PM contact sites to focal adhesions   Résumé : Cell motility processes highly depend on the membrane distribution of Phosphoinositides, giving rise to cytoskeleton reshaping and membrane trafficking events. Membrane contact sites serve as platforms for…

L'équipe Courtier a contribué à la publication d'un nouvel article dans BMC Bioinformatics : CNCA aligns small annotated genomes   Résumé : Background To explore the evolutionary history of sequences, a sequence alignment is a first and necessary step, and its quality is crucial. In the context of the study of the proximal origins of SARS-CoV-2 coronavirus,…
