    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.

    Point of View: Strategies from UW-Madison for rescuing biomedical research in the US

    Judith Kimble et al.
    A cross-campus, cross-career stage and cross-disciplinary series of discussions at a large public university has produced a series of recommendations for addressing the problems confronting the biomedical research community in the US.

    Research: Bias in the reporting of sex and age in biomedical research on mouse models

    Oscar Flórez-Vargas et al.
    A text-mining study suggests that about half of the papers reporting the results of experiments on mice do not report the sex and age of the mice.

    Human embryonic lung epithelial tips are multipotent progenitors that can be expanded in vitro as long-term self-renewing organoids

    Marko Z Nikolić et al.
    Improved characterisation of human embryonic lung development highlights human-mouse differences and facilitates the development of defined culture conditions for the expansion of self-renewing, multipotent human lung epithelial progenitor cells.

    Presynaptic morphology and vesicular composition determine vesicle dynamics in mouse central synapses

    Laurent Guillaud et al.
    In central synapses, the mobility and supply of synaptic vesicles are determined by two independent biological factors: the morphological and structural organization of nerve terminals and the molecular signature of vesicles.

    BRAFV600E cooperates with CDX2 inactivation to promote serrated colorectal tumorigenesis

    Naoya Sakamoto et al.
    Genetic analyses reveal how CDX2 and BRAF defects seen in serrated colorectal cancer (CRCs), a poor prognosis CRC subset, cooperate in tumorigenesis in humans and in a mouse cancer model.

    Comparative genetic screens in human cells reveal new regulatory mechanisms in WNT signaling

    Andres M Lebensohn et al.
    A systematic genetic analysis comprising seven genome-wide screens in haploid human cells uncovered new regulatory mechanisms at most levels in the WNT signaling pathway.
