    Connexin 43 hemichannels regulate mitochondrial ATP generation, mobilization, and mitochondrial homeostasis against oxidative stress

    Jingruo Zhang, Manuel A Riquelme ... Jean X Jiang
    Mitochondrial Cx43 hemichannels regulate ATP generation by mediating K+, H+, and ATP transfer across the mitochondrial inner membrane and the interaction with mitochondrial ATP synthase, contributing to maintenance of mitochondrial redox and cell protection under oxidative stress.

    Glutathione in the nucleus accumbens regulates motivation to exert reward-incentivized effort

    Ioannis Zalachoras, Eva Ramos-Fernández ... Carmen Sandi
    The capacity to sustain effort to obtain rewards over time depends on the levels of the antioxidant glutathione in the nucleus accumbens - a brain region critical for motivated behavior - and can be boosted with a nutritional intervention (N-acetylcysteine).

    NaV1.1 is essential for proprioceptive signaling and motor behaviors

    Cyrrus M Espino, Cheyanne M Lewis ... Theanne N Griffith
    The voltage-gated sodium channel Nav1.1 is identified as an essential component of the proprioceptive transmission machinery that is required in vivo for normal motor behavior.

    Computational model of the full-length TSH receptor

    Mihaly Mezei, Rauf Latif, Terry F Davies
    Molecular dynamics simulation of the full-length TSH receptor, a major human autoantigen whose full structure remains uncertain, showed that its linker region is an intrinsically disordered protein, explaining the difficulty of obtaining an experimental structure.

    Lack of ownership of mobile phones could hinder the rollout of mHealth interventions in Africa

    Justin T Okano, Joan Ponce ... Sally Blower
    Due to current levels of mobile phone ownership in Africa, it may only be possible to scale up mHealth interventions in a few countries, but not in the vast majority of the 33 countries that encompass ~60% of Africa's population.

    Augmin prevents merotelic attachments by promoting proper arrangement of bridging and kinetochore fibers

    Valentina Štimac, Isabella Koprivec ... Iva M Tolić
    STED microscopy of human mitotic spindles reveals how augmin-nucleated microtubules protect the cell from erroneous kinetochore-microtubule attachments and ensure a highly organized architecture of the spindle required for mitotic fidelity.

    Sonic hedgehog-dependent recruitment of GABAergic interneurons into the developing visual thalamus

    Rachana Deven Somaiya, Katelyn Stebbins ... Michael A Fox
    Retinal ganglion cell axons release the morphogen sonic hedgehog which signals through astrocytes to induce the migration of inhibitory interneurons into the developing visual thalamus.

    Contrasting effects of Ksr2, an obesity gene, on trabecular bone volume and bone marrow adiposity

    Gustavo A Gomez, Charles H Rundle ... Subburaman Mohan
    Obese Ksr2 mutant mice have increased trabecular bone but decreased marrow adiposity and are more prone to fractures, thus providing a useful model to understand how stem cells can be manipulated to produce bone at the expense of marrow fat.

    Contextual effects in sensorimotor adaptation adhere to associative learning rules

    Guy Avraham, Jordan A Taylor ... Samuel D McDougle
    Core associative learning phenomena that are observed in studies of eyeblink conditioning are also observed in sensorimotor adaptation, pointing to a common framework for these distinct cerebellar-dependent motor learning processes.

    Neuronal temperature perception induces specific defenses that enable C. elegans to cope with the enhanced reactivity of hydrogen peroxide at high temperature

    Francesco A Servello, Rute Fernandes ... Javier Apfeld
    C. elegans nematodes can assess faithfully the threat that H2O2 poses by coupling the induction of their H2O2 defenses to the perception of high temperature—an inherent enhancer of the reactivity of H2O2.
