    Quantitative and functional interrogation of parent-of-origin allelic expression biases in the brain

    Julio D Perez, Nimrod D Rubinstein ... Catherine Dulac
    A subset of genes in the mouse brain show dynamically regulated and unequal expression of maternally and paternally derived variants, with implications for brain development and function.

    Selective transduction and photoinhibition of pre-Bötzinger complex neurons that project to the facial nucleus in rats affects nasofacial activity

    Mariana R Melo, Alexander D Wykes ... Andrew M Allen
    The pre-Bötzinger complex, known as the kernel for the breathing generation, consists of separate subpopulations of neurons that project to specific nuclei to coordinate respiratory rhythmicity with different physiological behaviors, such as nasofacial activity.

    Profilin and formin constitute a pacemaker system for robust actin filament growth

    Johanna Funk, Felipe Merino ... Peter Bieling
    Profilin release from the filament end controls the speed of actin growth at physiological conditions.

    Synergy between Wsp1 and Dip1 may initiate assembly of endocytic actin networks

    Connor J Balzer, Michael L James ... Brad J Nolen
    An activator of branching nucleation by Arp2/3 complex directly synergizes with an activator of linear filament nucleation to initiate assembly of actin networks that drive endocytosis.

    FXR1 regulates transcription and is required for growth of human cancer cells with TP53/FXR2 homozygous deletion

    Yichao Fan, Jiao Yue ... Bin Xiang
    Functional and mechanistic analyses of cancer cells containing homozygous deletion of TP53 and FXR2 reveal that inhibition of FXR1 blocks cell proliferation in a collateral lethality manner, opening an avenue to develop therapies targeting such cancers.

    NPAS4 in the medial prefrontal cortex mediates chronic social defeat stress-induced anhedonia-like behavior and reductions in excitatory synapses

    Brandon W Hughes, Benjamin M Siemsen ... Makoto Taniguchi
    Social defeat stress induces transcription factor Npas4 expression in the medial prefrontal cortex and its chronic stress-induced changes in excitatory synaptic transmission, reduction of dendritic spine density, and anhedonia-like behaviors.

    PreBötzinger complex neurons drive respiratory modulation of blood pressure and heart rate

    Clément Menuet, Angela A Connelly ... Andrew M Allen
    The PreBötzinger complex, which contains neurons that are the kernel for inspiratory rhythm generation, also contains sympathoexcitatory and parasympathoinhibitory neurons that drive respiratory-phase oscillations in blood pressure and heart rate.

    Selective targeting of unipolar brush cell subtypes by cerebellar mossy fibers

    Timothy S Balmer, Laurence O Trussell
    Distinct inputs to the cerebellum make contact on specific subtypes of target neurons.

    Low-affinity integrin states have faster ligand-binding kinetics than the high-affinity state

    Jing Li, Jiabin Yan, Timothy A Springer
    Faster ligand-binding kinetics of integrin low-affinity states suggests that integrin binding to ligand and intracellular adapters and the actin cytoskeleton precedes their stabilization, together with tensile force, of the high-affinity, extended-open integrin conformation.

    The peroxisome counteracts oxidative stresses by suppressing catalase import via Pex14 phosphorylation

    Kanji Okumoto, Mahmoud El Shermely ... Yukio Fujiki
    H2O2-induced phosphorylation at Ser232 of Pex14 spatiotemporally regulates peroxisomal import of catalase, functioning in counteracting action against oxidative stress by the increase of cytosolic catalase.
