    Acute intermittent hypoxia enhances corticospinal synaptic plasticity in humans

    Lasse Christiansen, MA Urbin ... Monica A Perez
    Acute intermittent hypoxia is a noninvasive approach that enhances corticospinal function in humans, likely through alterations in corticospinal-motoneuronal synaptic transmission.

    Acetylation of BMAL1 by TIP60 controls BRD4-P-TEFb recruitment to circadian promoters

    Nikolai Petkau, Harun Budak ... Gregor Eichele
    Acetylation of the circadian transcription factor BMAL1 by the acetyltransferase TIP60 is crucial for recruitment of the pause release factors to clock gene promoters and productive elongation of these genes.

    Connexin26 hemichannels with a mutation that causes KID syndrome in humans lack sensitivity to CO2

    Louise Meigh, Naveed Hussain ... Nicholas Dale
    Building on previous work (Meigh et al., 2013) we show that A88V, a mutation in connexin26 (Cx26) that causes Keratitis-Ichthyosis-Deafness (KID) syndrome in humans, is linked to a lack of sensitivity to CO2 by Cx26 hemichannels.

    Precardiac deletion of Numb and Numblike reveals renewal of cardiac progenitors

    Lincoln T Shenje, Peter Andersen ... Chulan Kwon
    Cardiac progenitors remain undifferentiated and expansive in the second pharyngeal arch that serves as a microenvironment, and Numb and Numblike are required for their renewal.

    IFN-γ mediates Paneth cell death via suppression of mTOR

    Alessandra Araujo, Alexandra Safronova ... Felix Yarovinsky
    A major Th1 cytokine IFN-γ mediates mitochondrial damage that leads to mTORC1 inhibition and Paneth cells death.

    IRAK2 directs stimulus-dependent nuclear export of inflammatory mRNAs

    Hao Zhou, Katarzyna Bulek ... Xiaoxia Li
    The stimulation of lipopolysaccharides induced nuclear localization of IRAK2 to facilitate nuclear export of a specific subset of inflammation-related messenger RNAs for translation in murine macrophages.

    Multiple cullin-associated E3 ligases regulate cyclin D1 protein stability

    Ke Lu, Ming Zhang ... Di Chen
    Cyclin D1 protein stability is regulated by ubiquitin-proteasome mechanism mediated by multiple E3 ligases, including newly identified Keap1, DDB2, and WSB2.
