Palancade Lab / ProtéoSeine – Cellular imbalance of specific RNA binding proteins associates with harmful R-loops

The Palancade Lab and the ProtéoSeine 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.…

Guichet Lab – Sheltered load in fungal mating-type chromosomes revealed by fitness experiments

The Guichet Lab contributed to a new article published in Journal of Evolutionary Biology: Sheltered load in fungal mating-type chromosomes revealed by fitness experiments Abstract: Sex chromosomes and mating-type chromosomes can carry large regions with suppressed recombination. As a result of a lower efficacy of selection, recessive deleterious mutations are expected to accumulate in these non-recombining regions.…

Greenberg Lab – PIK3R1 and G0S2 are human placenta-specific imprinted genes associated with germline-inherited maternal DNA methylation

The Greenberg lab contributed to a new publication in Epigenetics: PIK3R1 and G0S2 are human placenta-specific imprinted genes associated with germline-inherited maternal DNA methylation   Abstract: Genomic imprinting is the parent-of-origin specific monoallelic expression of genes that result from complex epigenetic interactions. It is often achieved by monoallelic 5-methylcytosine, resulting in the formation of differentially methylated regions (DMRs). These show a…

Romet-Lemonne/Jégou Lab – Continuous self-repair protects vimentin intermediate filaments from fragmentation

The Romet-Lemonne/Jégou Lab published a new publication in PNAS: Continuous self-repair protects vimentin intermediate filaments from fragmentation Abstract: Intermediate filaments are key regulators of cell mechanics. Vimentin, a type of intermediate filament expressed in mesenchymal cells and involved in migration, forms a dense network in the cytoplasm that is constantly remodeling through filament transport, elongation/shortening, and subunit…

Ladoux/Mege Lab – Osmotic pressure induces unexpected relaxation of contractile 3D microtissue

The Ladoux/Mège Lab contributed to the publication of a new article in The European Physical Journal E: Osmotic pressure induces unexpected relaxation of contractile 3D microtissue   Abstract: 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 tissue…

Minc Lab – Cell division: Size-scaling cytoplasmic flows transport chromosomes to the right spot

The Minc Lab published a new article in Current Biology: Cell division: Size-scaling cytoplasmic flows transport chromosomes to the right spot   Abstract: 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 that advect…

Minc Lab – Dynamic clamping induces rotation-to-beating transition of pinned filaments in gliding assays

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…

ProtéoSeine – Electron Transfer Dissociation and Synchrotron UV Photodissociation of Trapped Sodiated Ions Produced From Polyacrylates by Electrospray Ionization

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…
