Khokha and colleagues report that lack of the metalloproteinase inhibitors TIMP1 and TIMP3 in female mice increases the size of the mammary basal stem cell pool and that this is maintained in ageing mice.
Visentin and colleagues find a role for the FEAR network and Cdc5 in anaphase spindle elongation involving Cdc14-mediated dephosphorylation of the kinesin Cin8.
Spatz and colleagues report that intercellular pulling forces between leader and follower cells in migrating epithelial sheets regulate merlin subcellular localization and the crosstalk between merlin and Rac1 to promote collective cell migration.
Castanon, González-Gaitán and colleagues report that Sara endosomes can regulate asymmetric cell division by unequally positioning endocytosed Notch ligand in one daughter cell.
Bar-Eli and colleagues report that CREB-mediated downregulation of the RNA-editing enzyme ADAR1 results in decreased adenosine-to-inosine editing of miR-455-5p, which enhances melanoma growth and metastasis.
Debnath and colleagues report that the E2-like enzyme ATG3 is a target for ATG12 conjugation. ATG12–ATG3 conjugates interact with the ESCRT-associated protein Alix and regulate late endosome localization and exosome biogenesis.
Zhang, Cuervo and colleagues find that Huntingtin (Htt), which is commonly mutated in Huntington disease, regulates selective autophagy. Htt enhances interactions between p62, LC3 and ubiquitylated cargo and derepresses ULK1 kinase activity.
Westlake and colleagues discover that membrane shaping EHD proteins participate in ciliogenesis by taking part in ciliary vesicle formation and transition zone protein recruitment.
Magness and colleagues present a microwell-based culture system to analyse interactions between intestinal stem cells (ISCs) and Paneth cells, and show that their direct contact enhances formation of ISC-derived organoids.
The protrusion of cilia into extracellular space provides cells with sensors of localized environmental cues that include fluid flow, mechanical force and important growth factors such as Hedgehog. Live imaging has now captured the initial appearance of cilia during embryogenesis, and defined lineage-specific determinants that restrict extra-embryonal ciliogenesis.
Macrophages facilitate tumour progression, but it is unclear whether this capability is influenced by tumour-initiating cells. Glioblastoma stem cells are now shown to secrete periostin, a matrix protein that recruits protumoral macrophages and enhances glioblastoma progression in mice.
Elliott et al. use high-resolution imaging, microfabrication and computational analyses to show that the interplay between cell-surface curvature and activity and cortical recruitment of myosin II, control cell migration in 3D matrices.
Wang and colleagues report that cancer-cell-derived extracellular vesicles that contain miR-122 reprogram glucose metabolism of premetastatic niche cells to alter nutrient availability and promote metastasis.
Ding and colleagues report that blood platelets recruited to the lung by injury release the chemokine SDF-1, which interacts with its receptor CXCR4 on pulmonary capillary endothelial cells and thereby initiates alveolar regeneration.
Hyman, Muller and colleagues characterize how mitotic rounding forces relate to the dynamics of the actomyosin cortex. They find that myosin II enables the cell to resist deformation.
Cunningham et al. characterize the ubiquitin chain linkages regulated by the opposing activities of the E3 ligase parkin and the deubiquitylation enzyme USP30 on mitochondria.
Anderson and colleagues report that, although mouse embryonic tissues form primary cilia, in cells destined for extraembryonic lineages, the activities of aurora kinase A and the tubulin deacetylase HDAC6 inhibit ciliogenesis.
Bao and colleagues report that glioblastoma cancer stem cells produce periostin, which in turn recruits tumour-associated macrophages to the tumour site to foster growth.
