    An oxygen-insensitive Hif-3α isoform inhibits Wnt signaling by destabilizing the nuclear β-catenin complex

    Peng Zhang et al.
    Hif/Hif-3α has two distinct roles in cells: activating HRE-dependent gene expression and binding to β-catenin to destabilize the nuclear β-catenin complex.

    R-spondins can potentiate WNT signaling without LGRs

    Andres M Lebensohn, Rajat Rohatgi
    R-spondins 2 and 3 can potentiate WNT signaling in the absence of LGRs through interactions with ZNRF3/RNF43 E3 ubiquitin ligases and heparan sulfate proteoglycans, defining two alternative modes of R-spondin-mediated signaling.

    Restraint of presynaptic protein levels by Wnd/DLK signaling mediates synaptic defects associated with the kinesin-3 motor Unc-104

    Jiaxing Li et al.
    Synaptic defects previously attributed to loss of kinesin function are found to be mediated by the Wnd/DLK axonal injury signaling pathway, which restrains the total levels of presynaptic proteins in response to their accumulation.

    Conformational change of Dishevelled plays a key regulatory role in the Wnt signaling pathways

    Ho-Jin Lee et al.
    The ligand-binding pocket of the Dishevelled PDZ domain can be occupied by Dishevelled's own highly conserved C-terminus, inducing a closed conformation that is ‘opened’ when Wnt signaling stimulates interaction between Frizzled and Dishevelled.

    miR-142 regulates the tumorigenicity of human breast cancer stem cells through the canonical WNT signaling pathway

    Taichi Isobe et al.
    Insights into the roles and mechanisms of two of the miRNAs upregulated in human breast cancer stem cells in at least some breast cancers are presented.

    Non-canonical Wnt signaling regulates junctional mechanocoupling during angiogenic collective cell migration

    Joana R Carvalho et al.
    Analysis of axial polarity distributions shows that Wnt5a regulates collective cell migration in vivo by stabilizing vinculin at adherens junctions and fine-tuning mechanocoupling between neighbouring cells.

    Wnt/PCP controls spreading of Wnt/β-catenin signals by cytonemes in vertebrates

    Benjamin Mattes et al.
    Wnt signaling regulates its effective signaling range by controlling Wnt ligand transport on signaling filopodia within vertebrate tissues.

    R-spondin signalling is essential for the maintenance and differentiation of mouse nephron progenitors

    Valerie PI Vidal et al.
    In the developing kidney, secreted molecules of the R-spondin family control progenitor cell proliferation and nephron formation by permitting WNT/β-catenin signalling.

    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.

    Embryonic attenuated Wnt/β-catenin signaling defines niche location and long-term stem cell fate in hair follicle

    Zijian Xu et al.
    Long-term hair follicle stem cells arise by embryonic progenitor cells occupying a niche location that is defined by attenuated Wnt/β-catenin signal.
