The Minc Lab contributed to the publication of a new article in Biophysical Journal: Inferring diffusion, reaction, and exchange parameters from imperfect FRAP Abstract: Fluorescence recovery after photobleaching (FRAP) is broadly used to investigate the dynamics of molecules in cells and tissues, notably to quantify diffusion coefficients. FRAP is based on the spatiotemporal imaging of fluorescent molecules…

The Ribes/Nedelec Lab contributed to the publication to a new article Science Advances: GPR161 mechanosensitivity at the primary cilium drives neuronal saltatory migration   Abstract: The saltatory migration of neurons is essential for brain formation. Whether mechanical stimuli regulate this process is unknown. Here, we show that the primary cilium acts as a mechanical sensor through GPR161. Using…

The Wassmann Lab contributes to the book Mammalian Oocyte Development: “JessTM Simple WesternTM”: A New Technology to Assess Protein Abundance in Mouse Oocytes Abstract: Traditional Western blot technology coupled with two-dimensional  SDS-PAGE has been used for decades to detect specific proteins in extracts. Here we describe an automated Western technology based on protein separation by capillary assay. Only…

The Jackson/Verbavatz Lab contributes to the publication of a new article in Traffic: Eukaryote-Wide Distribution of a Family of Longin Domain-Containing GAP Complexes for Small GTPases Abstract: Arf and Rab family small GTPases and their regulators, GTPase-activating proteins (GAPs) and guanine nucleotide exchange factors (GEFs), play a central role in membrane trafficking. In this study, we focused…

The Gazave contribued to a new article published in BMC Genomics: A genome resource for the marine annelid Platynereis spp Abstract: The marine annelid Platynereis dumerilii is a model organism used in many research areas including evolution and development, neurobiology, ecology and regeneration. Here we present the genomes of P. dumerilii (laboratory culture reference and a single…

The Veitia Lab published a new article in Journal of inherited metabolic disease: Gene Dosage Sensitivity and Human Genetic Diseases Abstract: Here we review the historical background and contemporary insights into genetic dominance, focusing on haploinsufficiency (HI), that is, when the function of only one allele of a gene is not enough to ensure a normal phenotype…

The Romet-Lemonne/Jégou lab contributed to the publication of a new article in médecine/science: Caveolin-1 stiffens the plasma membrane and limits transcellular tunnel expansion Lemichez E, Morel C, Leduc C, Bassereau P. La cavéoline-1 rigidifie la membrane plasmique et limite l’expansion de tunnels transcellulaires [Caveolin-1 stiffens the plasma membrane and limits transcellular tunnel expansion]. Med Sci (Paris).…

The Ladoux/Mege Lab contributed to the publication of a new article in Nature Communications: A multicellular star-shaped actin network underpins epithelial organization and connectivity Abstract: Epithelial tissues withstand external stresses while maintaining structural stability. Bicellular junctions and the actomyosin network support epithelial integrity, packing and remodelling. While their role in development and disease are well studied, their…

The ProteoSeine platform contributed to the publication of a new article in Journal of biological chemistry: Structural and functional characterization of CREB-binding protein (CREBBP) as a histone propionyltransferase Abstract: In addition to histone acetylation, histone lysine propionylation (such as the H3K18Pr mark) has recently attracted significant attention as a common and abundant modification linking the cellular metabolic…

The Palancade Lab and the ProteoSeine platform contributed to the publication of a new article in PLOS genetics: Cellular imbalance of specific RNA binding proteins associates with harmful R-loops Abstract: Understanding how the assembly of nascent mRNA into a ribonucleoprotein (mRNP) influences R-loop homeostasis is crucial for gaining insight into the cellular mechanisms that prevent genome instability.…
