Ladoux/Mege Lab – A multicellular star-shaped actin network underpins epithelial organization and connectivity

L'équipe Ladoux/Mege a contribué à la publication d'un nouvel article dans Nature Communications : A multicellular star-shaped actin network underpins epithelial organization and connectivity Résumé : 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,…

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

L'équipe Guichet a contribué à une nouvelle publication dans Journal of Evolutionary Biology : Sheltered load in fungal mating-type chromosomes revealed by fitness experiments Résumé : 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…

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

L'équipe Greenberg a contribué à la publication d'un nouvel article dans Epigenetics : PIK3R1 and G0S2 are human placenta-specific imprinted genes associated with germline-inherited maternal DNA methylation   Résumé : 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…
