    A role for PVRL4-driven cell–cell interactions in tumorigenesis

    Natalya N Pavlova, Christian Pallasch ... Stephen J Elledge
    A protein called PVRL4 has a central role in a number of cancers that originate in epithelial tissue, and anti-PVRL4 antibodies could be used to treat some of these cancers.

    AMP-activated protein kinase fortifies epithelial tight junctions during energetic stress via its effector GIV/Girdin

    Nicolas Aznar, Arjun Patel ... Pradipta Ghosh
    An effector of AMPK is essential for the kinase and its pharmacological activators, including Metformin, to strengthen cell-cell junctions and preserve epithelial cell polarity and barrier functions in the face of energetic stress, as well as to suppress oncogenesis.

    KSR1- and ERK-dependent translational regulation of the epithelial-to-mesenchymal transition

    Chaitra Rao, Danielle E Frodyma ... Robert E Lewis
    A key Ras-driven signaling pathway stimulates the preferential translation of an effector, EPSTI1, that is both necessary and sufficient for the epithelial-to-mesenchymal transition-like phenotype in colorectal cancer cells.

    CRISPR/Cas9 mutagenesis invalidates a putative cancer dependency targeted in on-going clinical trials

    Ann Lin, Christopher J Giuliano ... Jason M Sheltzer
    A putative therapeutic target undergoing clinical trials in breast cancer is non-essential and the drug used in those trials blocks cell division through an off-target effect.

    Collagen-rich omentum is a premetastatic niche for integrin α2-mediated peritoneal metastasis

    Yen-Lin Huang, Ching-Yeu Liang ... Viola Heinzelmann-Schwarz
    Inhibition of ITGA2-mediated cancer cell-collagen interaction or targeting focal adhesion kinase activity may present an opportunity for therapeutic intervention of metastatic spread in ovarian cancer.

    EphrinB2 drives perivascular invasion and proliferation of glioblastoma stem-like cells

    Benjamin Krusche, Cristina Ottone ... Simona Parrinello
    EphrinB2 promotes glioblastoma stem-like cell malignancy through the interplay of cell-autonomous and non-cell-autonomous mechanisms and its targeting suppresses tumourigenesis in preclinical models of human glioblastoma.

    MELK expression correlates with tumor mitotic activity but is not required for cancer growth

    Christopher J Giuliano, Ann Lin ... Jason M Sheltzer
    Cancer cells can grow in vitro and in vivo in the absence of maternal embryonic leucine zipper kinase (MELK).

    TAZ-CAMTA1 and YAP-TFE3 alter the TAZ/YAP transcriptome by recruiting the ATAC histone acetyltransferase complex

    Nicole Merritt, Keith Garcia ... Munir R Tanas
    The C terminal fusion partners of TAZ-CAMTA1, YAP-TFE3 and potentially other TAZ/YAP fusion proteins in cancer recruit epigenetic modifiers that modulate a baseline TEAD-based transcriptional program.

    LAP2alpha maintains a mobile and low assembly state of A-type lamins in the nuclear interior

    Nana Naetar, Konstantina Georgiou ... Roland Foisner
    The lamin A/C binding protein LAP2α inhibits formation of higher order lamin structures in the nuclear interior in a lamin A/C-phosphorylation-independent manner, thereby regulating chromatin mobility.

    Modeling and mechanical perturbations reveal how spatially regulated anchorage gives rise to spatially distinct mechanics across the mammalian spindle

    Pooja Suresh, Vahe Galstyan ... Sophie Dumont
    Coarse-grained modeling of mammalian kinetochore-fiber shapes generated under microneedle manipulation reveals the need for lateral anchorage 1-3 μm from the kinetochore to robustly preserve their orientation in the spindle center, promoting mechanical integrity in the dynamic spindle.
