    Estrogen receptor alpha in the brain mediates tamoxifen-induced changes in physiology in mice

    Zhi Zhang et al.
    Estrogen receptor alpha in the hypothalamus is required for the effects of chronic tamoxifen treament on gene expression, thermoregulation, bone, and movement in mice.

    C. elegans orthologs MUT-7/CeWRN-1 of Werner syndrome protein regulate neuronal plasticity

    Tsung-Yuan Hsu et al.
    The olfactory learning of Caenorhabditis elegans shows that the exonuclease and helicase domains of human Werner syndrome protein (WRN) coordinately regulate the biogenesis of small interfering RNAs to promote neuronal plasticity.

    The mTORC1-mediated activation of ATF4 promotes protein and glutathione synthesis downstream of growth signals

    Margaret E Torrence et al.
    ATF4 is a metabolic effector of mTORC1 signaling, co-opted to induce gene targets involved in amino acid synthesis, uptake, and tRNA charging, contributing to mTORC1-driven protein and glutathione synthesis.

    Bidirectional regulation of glial potassium buffering – glioprotection versus neuroprotection

    Hailun Li et al.
    A neuromodulatory circuit bidirectionally regulates the glial capacity to buffer ions and water in response to changes in neuronal excitation in order to balance glial versus neuronal protection.

    Cystic proliferation of germline stem cells is necessary to reproductive success and normal mating behavior in medaka

    Luisa F Arias Padilla et al.
    In medaka fish, the reduction of cystic proliferation of germ stem cells declines gametogenesis, reproduction success, and male sexual behavior, with a decrease of mating vigor.
