    Active and water-soluble form of lipidated Wnt protein is maintained by a serum glycoprotein afamin/α-albumin

    Emiko Mihara, Hidenori Hirai ... Junichi Takagi
    Lipidated and highly hydrophobic Wnt ligands form a complex with the serum glycoprotein afamin, and can be purified and stored in a biologically active form without detergents.

    Downregulation of Dickkopf-3, a Wnt antagonist elevated in Alzheimer’s disease, restores synapse integrity and memory in a disease mouse model

    Nuria Martin Flores, Marina Podpolny ... Patricia C Salinas
    The Wnt antagonist DKK3 is a key regulator of excitatory and inhibitory synapses, and its downregulation in the hippocampus restores synaptic connectivity and memory in an Alzheimer's disease mouse model.

    Arrayed CRISPRi and quantitative imaging describe the morphotypic landscape of essential mycobacterial genes

    Timothy J de Wet, Kristy R Winkler ... Digby F Warner
    A high-throughput functional genomics approach combining inducible CRISPR-interference and quantitative imaging yields an atlas of 'phenoprints' to guide gene function assignments, identify metabolic pathway-specific morphotypes, and inform antibiotic mechanism-of-action studies.

    Two FGFRL-Wnt circuits organize the planarian anteroposterior axis

    M Lucila Scimone, Lauren E Cote ... Peter W Reddien
    Single-cell RNA sequencing identifies an adult regional gene expression map in planarian muscle that includes two FGFRL-Wnt circuits controlling head and trunk tissue pattern.

    Sox17 and β-catenin co-occupy Wnt-responsive enhancers to govern the endoderm gene regulatory network

    Shreyasi Mukherjee, Praneet Chaturvedi ... Aaron M Zorn
    Genomic analysis of Xenopus gastrula reveal that the transcription factor Sox17 interacts with the Wnt signaling effector ß-catenin on enhancers to regulate the transcriptional program underlying endoderm germ layer formation.

    R-spondins engage heparan sulfate proteoglycans to potentiate WNT signaling

    Ramin Dubey, Peter van Kerkhof ... Rajat Rohatgi
    Heparan Sulfate Proteoglycans function as receptors for the R-spondins, a family of growth factors that amplify the strength of WNT signaling during development and in adult stem cells.

    Direct visualization of a native Wnt in vivo reveals that a long-range Wnt gradient forms by extracellular dispersal

    Ariel M Pani, Bob Goldstein
    Free, extracellular dispersal of Wnt proteins generates a long-range gradient during animal development and is required for signaling.

    Chondrocytes in the resting zone of the growth plate are maintained in a Wnt-inhibitory environment

    Shawn A Hallett, Yuki Matsushita ... Noriaki Ono
    Slow-cycling chondrocytes are maintained in a Wnt-inhibitory environment within the resting zone, unraveling a novel mechanism regulating maintenance and differentiation of parathyroid hormone-related protein (PTHrP)-expressing skeletal stem cells of the postnatal growth plate.

    Progenitors oppositely polarize WNT activators and inhibitors to orchestrate tissue development

    Irina Matos, Amma Asare ... Elaine Fuchs
    Progenitors establish a single-cell length WNT morphogen gradient to transmit signals directionally and differentially to neighbors.

    Evolution of thorax architecture in ant castes highlights trade-off between flight and ground behaviors

    Roberto A Keller, Christian Peeters, Patrícia Beldade
    Body shape and behavioural specializations found across the castes of ant species evolved together and reflect different abilities for ground behaviors.
