    53BP1 and USP28 mediate p53-dependent cell cycle arrest in response to centrosome loss and prolonged mitosis

    Chii Shyang Fong, Gregory Mazo ... Meng-Fu Bryan Tsou
    Tumor Protein p53 Binding Protein 1 and Ubiquitin Specific Peptidase 28 engage p53 to promote mitotic efficiency.

    Clathrin modulates vesicle scission, but not invagination shape, in yeast endocytosis

    Wanda Kukulski, Andrea Picco ... Marko Kaksonen
    Building on previous work (Picco et al., 2015), we use a hybrid imaging approach to address the role of clathrin during endocytosis: we find that it has no role in shaping or elongating membrane invaginations, but it does contribute to the regularity of vesicle scission.

    Nerve growth factor receptor negates the tumor suppressor p53 as a feedback regulator

    Xiang Zhou, Qian Hao ... Hua Lu
    The nerve growth factor receptor (NGFR) protein regulates p53 via two negative feedback mechanisms, which are hijacked by cancer cells.

    The anticancer natural product ophiobolin A induces cytotoxicity by covalent modification of phosphatidylethanolamine

    Christopher Chidley, Sunia A Trauger ... Erin K O'Shea
    An unbiased genetic screen in human cells shows that the molecular target of a natural product with promising anticancer activity is a membrane phospholipid.

    PROP1 triggers epithelial-mesenchymal transition-like process in pituitary stem cells

    María Inés Pérez Millán, Michelle L Brinkmeier ... Sally A Camper
    The transcription factor PROP1 controls a genetic network that drives pituitary stem cells to undergo an epithelial-to-mesenchymal-like transition and differentiate.

    Secretion of protein disulphide isomerase AGR2 confers tumorigenic properties

    Delphine Fessart, Charlotte Domblides ... Frederic Delom
    Epithelial tumors secrete the ER-resident AGR2 in the extracellular matrix to function as a novel essential microenvironmental regulator of epithelial tissue architecture, which leads to tumorigenicity.

    Golgi self-correction generates bioequivalent glycans to preserve cellular homeostasis

    Haik Mkhikian, Christie-Lynn Mortales ... Michael Demetriou
    Structurally dissimilar N-glycans can be functionally equivalent, and are produced via a self-correcting feature of the Golgi.

    MiniCORVET is a Vps8-containing early endosomal tether in Drosophila

    Péter Lőrincz, Zsolt Lakatos ... Gábor Juhász
    An unconventional endosomal tether in Drosophila melanogaster only has four of the six subunits found in the yeast complex.

    A mitofusin-dependent docking ring complex triggers mitochondrial fusion in vitro

    Tobias Brandt, Laetitia Cavellini ... Mickaël M Cohen
    A combination of an in vitro mitochondrial fusion assay with electron cryo-tomography (cryo-ET) reveals distinct steps and protein complexes during mitofusin-dependent fusion between adjacent mitochondrial outer membranes.

    In vivo super-resolution RESOLFT microscopy of Drosophila melanogaster

    Sebastian Schnorrenberg, Tim Grotjohann ... Stefan Jakobs
    Building on previous work (Grotjohann et al., 2012), low-light super-resolution microscopy has been performed on living transgenic Drosophila larvae and tissues.
