    A plasma membrane template for macropinocytic cups

    Douwe M Veltman, Thomas D Williams ... Robert R Kay
    Rings of actin polymerisation that form around PIP3/Ras patches in the cell membrane drive the formation of macropinocytic cups.

    Akt1-Inhibitor of DNA binding2 is essential for growth cone formation and axon growth and promotes central nervous system axon regeneration

    Hyo Rim Ko, Il-Sun Kwon ... Jee-Yin Ahn
    Akt mediated S14 phosphorylation of Id2 augments its protein stability and growth cone localization, promoting growth cone formation and axon growth in the developing neuron and contributing to axon regeneration in the damaged hippocampus slice.

    Differentiation alters stem cell nuclear architecture, mechanics, and mechano-sensitivity

    Su-Jin Heo, Tristan P Driscoll ... Robert L Mauck
    Nuclear reorganization and stiffening accompanies mesenchymal stem cell differentiation, resulting in increased sensitivity to mechanical perturbation.

    Cell culture-based profiling across mammals reveals DNA repair and metabolism as determinants of species longevity

    Siming Ma, Akhil Upneja ... Vadim N Gladyshev
    Profiling of fibroblasts across mammals captures differences in longevity at the level of global gene expression and metabolite levels and reveals pathways that define these differences.

    Labeling proteins inside living cells using external fluorophores for microscopy

    Kai Wen Teng, Yuji Ishitsuka ... Paul R Selvin
    A toxin is used to introduce an otherwise cell-impermeant fluorophore-antibody (or some thing which is equally specific) to bind to an intracellular protein which allows for super resolution imaging and single particle tracking inside the living cell.

    Sec24 phosphorylation regulates autophagosome abundance during nutrient deprivation

    Saralin Davis, Juan Wang ... Susan Ferro-Novick
    Phosphorylation of a core trafficking component, the COPII coat subunit Sec24, regulates cross-talk between the secretory and autophagy machinery during starvation.

    BRAF activates PAX3 to control muscle precursor cell migration during forelimb muscle development

    Jaeyoung Shin, Shuichi Watanabe ... Thomas Braun
    Genetic and biochemical approaches identify a new component of the cellular signaling machinery driving migration of limb muscle precursor cells during mouse embryogenesis and reveal the underlying molecular mechanism.

    Calcium-mediated actin reset (CaAR) mediates acute cell adaptations

    Pauline Wales, Christian E Schuberth ... Roland Wedlich-Söldner
    Calcium influx during acute cell stimulation triggers a global actin reset in mammalian cells, which is linked to plasma membrane repair and transcription and has implications for our understanding of cell migration, cancer, inflammation and cell stress response.

    An evidence based hypothesis on the existence of two pathways of mitochondrial crista formation

    Max E Harner, Ann-Katrin Unger ... Walter Neupert
    Lamellar and tubular cristae in mitochondria form by two different molecular pathways that form both involve F1FO-ATP synthase dimers and the MICOS complex, but formation of lamellar cristae also relies on Mgm1/Opa1.

    Control of the structural landscape and neuronal proteotoxicity of mutant Huntingtin by domains flanking the polyQ tract

    Koning Shen, Barbara Calamini ... Judith Frydman
    The polyQ tract of pathogenic Huntingtin causes aggregation when expanded in Huntington’s disease, but its two flanking domains control its conformational landscape, proteostasis and neurotoxicity.
