  • Basal cells in Xenopus mucociliary epithelium

    Haas et al. using Xenopus mucociliary epidermis, the mouse airway, and human airway basal cells demonstrate that wnt is necessary for cilia formation during differentiaion. In basal cells, wnt prevents specification of epithelial cell types by activating the master transcription factor, ΔN-Tp63 which is required to retain basal cell stemness during development. Published in Cell Reports.

  • The Epigenetic Control of Pluripotent Signal Competence

    Gentsch et al. demonstrate that maternal pluripotency factors initiate epigeneic remodelling of thousands of regulatory elements on which signal mediators act to regionalise zygotic genome activity, specifying the three germ layers. Their discovery is a first step in understanding how proteins permit a cell type-specific signal response. Published in Nature Communications.

  • Single Amino Acid Change Underlies Distinct Roles of H2A.Z Subtypes in Human Syndrome

    Greenberg et al. published in Cell their study of the developmental disorder, Floating-Harbor syndrome (FHS) caused by mutations in the chromatin remodelling gene, SRCAP which functions through H2A.Z.2-containing nucleosomes, regulating AT-rich enhancers.

  • Roberto Mayor elected new member by EMBO

    Dr. Roberto Mayor, Professor of Developmental and Cellular Neurobiology at University College London’s Division of Biosciences, was elected by The European Molecular Biology Organization (EMBO) as a new member.

  • Defining the vertebrate cardiac proteome

    Federspiel et al. published in PLoS Biology their study identifying the core protein composition, complexes, and pathways in vertebrates from Xenopus to human heart. They reveal that each species shares a unique set of proteins with humans but not the other vertebrates studied.
