Duharcourt Lab / ImagoSeine / ProtéoSeine – The PIWI-interacting protein Gtsf1 controls the selective degradation of small RNAs in Paramecium

L'équipe Duharcourt a publié un nouvel article dans Nucleic Acids Research : The PIWI-interacting protein Gtsf1 controls the selective degradation of small RNAs in Paramecium   Résumé : Ciliates undergo developmentally programmed genome elimination, in which small RNAs direct the removal of transposable elements (TEs) during the development of the somatic nucleus. Twenty-five nucleotide scanRNAs (scnRNAs) are produced from…

Romet-Lemonne / Jegou Lab – HIV-1 budding requires cortical actin disassembly by the oxidoreductase MICAL1

L'équipe Romet-Lemonne/Jégou a contribué à la publication d'un nouvel article dans PNAS : HIV-1 budding requires cortical actin disassembly by the oxidoreductase MICAL1   Résumé : Many enveloped viruses bud from the plasma membrane that is tightly associated with a dense and thick actin cortex. This actin network represents a significant challenge for membrane deformation and scission, and…

Dumont Lab – Cell type-specific regulation by different cytokinetic pathways in the early embryo

L'équipe Dumont a contribué à un article publié dans microPublication Biology : Cell type-specific regulation by different cytokinetic pathways in the early embryo Résumé : Cytokinesis, the physical division of one cell into two, is typically assumed to use the same molecular process across animal cells. However, regulation of cell division can vary significantly among different cell…

Greenberg Lab – DNA methylation shapes the Polycomb landscape during the exit from naive pluripotency

L'équipe Greenberg a publié un nouvel article dans Nature structural & Molecular biology: DNA methylation shapes the Polycomb landscape during the exit from naive pluripotency Résumé : In mammals, 5-methylcytosine (5mC) and Polycomb repressive complex 2 (PRC2)-deposited histone 3 lysine 27 trimethylation (H3K27me3) are generally mutually exclusive at CpG-rich regions. As mouse embryonic stem cells exit…

Grange / Geigl Lab – The Population History of Domestic Sheep Revealed by Paleogenomes

L'équipe Grange / Geigl a publié un nouvel article dans Molecular biology and evolution : The Population History of Domestic Sheep Revealed by Paleogenomes   Résumé : Sheep was one of the first domesticated animals in Neolithic West Eurasia. The zooarchaeological record suggests that domestication first took place in Southwest Asia, although much remains unresolved about the precise…
