    Ral GTPases promote breast cancer metastasis by controlling biogenesis and organ targeting of exosomes

    Shima Ghoroghi et al.
    A combination of animal models reveal how the molecular mechanisms of exosome secretion (RalA/B-dependent) are linked to their cargo content and their function in breast cancer pre-metastatic niche formation.

    Deep-learning-based three-dimensional label-free tracking and analysis of immunological synapses of CAR-T cells

    Moosung Lee et al.
    Rapid, label-free, volumetric, and automated assessment of the immunological synapse dynamics is demonstrated by combining optical diffraction tomography and deep-learning-based segmentation, providing a new option for immunological research.

    The ESCRT machinery regulates retromer-dependent transcytosis of septate junction components in Drosophila

    Hendrik Pannen et al.
    A novel role of endosomal machineries retromer and ESCRT in membrane delivery of Drosophila septate junction components is required for maintenance of junction integrity and epithelial barrier function.

    Epidermal PAR-6 and PKC-3 are essential for larval development of C. elegans and organize non-centrosomal microtubules

    Victoria G Castiglioni et al.
    PAR-6 and PKC-3/aPKC are essential for postembryonic development of C. elegans and control the organization of non-centrosomal microtubule bundles in the epidermis, likely through recruitment of NOCA-1/Ninein.

    High-resolution transcriptional and morphogenetic profiling of cells from micropatterned human ESC gastruloid cultures

    Kyaw Thu Minn et al.
    Micropatterned differentiation of human ESCs generates gastrulation cell types – germ layers, extraembryonic, and primordial germ cells with primate characteristics – that show conserved sorting behaviors when dissociated and reseeded as single-cell mixture.

    AKAP6 orchestrates the nuclear envelope microtubule-organizing center by linking golgi and nucleus via AKAP9

    Silvia Vergarajauregui et al.
    AKAP6 is a site-specific adaptor required and sufficient to anchor centrosomal proteins and golgi to the nuclear envelope and establishes a non-centrosomal microtubule organization center (ncMTOC).

    16p11.2 microdeletion imparts transcriptional alterations in human iPSC-derived models of early neural development

    Julien G Roth et al.
    A model of in vitro human corticogenesis identifies alterations in gene expression caused by loss of 16p11.2 CNV genes in hiPSC-derived progenitor cells.

    Genome-wide CRISPR screen identifies noncanonical NF-κB signaling as a regulator of density-dependent proliferation

    Maria Fomicheva, Ian G Macara
    TRAF3, a negative regulator of noncanonical NF-κB signaling, maintains epithelial cell quiescence at confluence, and its loss triggers upregulation of immunity genes and prevents entry into G0 at high cell density.
