    A tudor domain protein, SIMR-1, promotes siRNA production at piRNA-targeted mRNAs in C. elegans

    Kevin I Manage et al.
    SIMR-1 acts downstream of the piRNA pathway to promote siRNA amplification by the Mutator complex and localizes to perinuclear foci distinct from Mutator foci, P granules and Z granules.

    Effects of fluorescent glutamate indicators on neurotransmitter diffusion and uptake

    Moritz Armbruster et al.
    Fluorescent glutamate indicators distort the time course of neurotransmitter diffusion and uptake by competing with transporters, an important caveat to consider when using iGluSnFR and its analogs.

    Distinct mitochondrial defects trigger the integrated stress response depending on the metabolic state of the cell

    Eran Mick et al.
    Mitochondrial electron transport chain dysfunction triggers the integrated stress response due to an asparagine deficiency downstream of impaired NADH oxidation in proliferating myoblasts, but not in differentiated myotubes.

    A CLC-ec1 mutant reveals global conformational change and suggests a unifying mechanism for the CLC Cl/H+ transport cycle

    Tanmay S Chavan et al.
    Crystallography together with electron-resonance spectroscopy, molecular-dynamics simulations, and transport measurements reveal the molecular details of protein conformational change, and how this change contributes to function in a CLC-type chloride/proton exchanger.

    IP3 mediated global Ca2+ signals arise through two temporally and spatially distinct modes of Ca2+ release

    Jeffrey T Lock, Ian Parker
    Cell-wide Ca2+ signals that regulate numerous cellular functions comprise dual Ca2+ release modes through IP3 receptors, punctate transients mediated by clustered receptors and spatiotemporally diffuse release through functionally distinct receptors.

    The Warburg Effect and lactate signaling augment Fgf-MAPK to promote sensory-neural development in the otic vesicle

    Husniye Kantarci et al.
    Glycolysis is locally enhanced and redirected in zebrafish to generate lactate, which functions as a signaling molecule to fully activate Fgf target genes required for proper sensory and neural development.

    Cortical bone maturation in mice requires SOCS3 suppression of gp130/STAT3 signalling in osteocytes

    Emma C Walker et al.
    Targeted SOCS3 null mice reveal that maturation of cortical bone comprises both pore closure and accumulation of high density bone, requiring local suppression of gp130-STAT3 in osteocytes and subsequent osteoclastogenesis.

    Characterization of the kinetic cycle of an ABC transporter by single-molecule and cryo-EM analyses

    Ling Wang et al.
    The conformational dynamics of multidrug resistance protein 1 (MRP1) are tracked in real time by single-molecule fluorescence resonance energy transfer experiments, which elucidate the rate-limiting mechanism of MRP1's transport cycle.

    Circulating myeloid cells invade the central nervous system to mediate cachexia during pancreatic cancer

    Kevin G Burfeind et al.
    Circulating myeloid cells invade the brain during pancreatic cancer, where they accumulate at a unique central nervous system interface and drive anorexia and muscle catabolism.

    Keratin 14-dependent disulfides regulate epidermal homeostasis and barrier function via 14-3-3σ and YAP1

    Yajuan Guo et al.
    Keratin filaments are revealed as novel regulators of entry into terminal differentiation in the epidermis via an ability to modulate YAP1 function and Hippo signaling.
