    Expression of SREBP-1c Requires SREBP-2-mediated Generation of a Sterol Ligand for LXR in Livers of Mice

    Shunxing Rong et al.
    SREBP-2 directly regulates genes involved in cholesterol homeostasis and indirectly regulates fatty acid synthesis through the production of a ligand responsible for the activation of LXR and SREBP-1c.

    Ribosomal mutations promote the evolution of antibiotic resistance in a multidrug environment

    James E Gomez et al.
    Mutations in several components of a bacterial ribosome are shown to broadly decrease antibiotic and stress sensitivity, and readily accessible reversion mutations allow these ribosomal mutations to serve as stepping stones to high level antibiotic resistance.

    CCR5 is a suppressor for cortical plasticity and hippocampal learning and memory

    Miou Zhou et al.
    Repression of the G protein-coupled chemokine receptor CCR5 enhances MAPK/CREB signaling, long-term potentiation, somatosensory cortical plasticity, and learning and memory, while CCR5 over-activation by viral proteins may contribute to HIV-associated cognitive deficits.

    Feeding state-dependent regulation of developmental plasticity via CaMKI and neuroendocrine signaling

    Scott J Neal et al.
    CaMKI and neuroendocrine signaling integrate information about food status to regulate a developmental decision in C. elegans.

    A robust activity marking system for exploring active neuronal ensembles

    Andreas T Sørensen et al.
    A new system for tagging activated neuronal population offers multiple advantages over existing systems based on immediate early genes, including greater sensitivity and specificity, and suitability for easy application in species other than mice.

    Structural elucidation of a novel mechanism for the bacteriophage-based inhibition of the RNA degradosome

    An Van den Bossche et al.
    A bacteriophage remodels the RNA metabolism machinery of a bacterial host to sequentially clear host transcripts and then stabilize the viral RNA.

    Misaligned feeding impairs memories

    Dawn H Loh et al.
    The time at which mice consume food can dramatically affect hippocampal-dependent biochemistry, physiology, and learned behavior.

    Snf1/AMPK promotes the formation of Kog1/Raptor-bodies to increase the activation threshold of TORC1 in budding yeast

    James E Hughes Hallett et al.
    The key Target of Rapamycin Complex (TORC1) component Kog1 moves into bodies during glucose starvation to limit reactivation of the complex.

    Ring finger protein 10 is a novel synaptonuclear messenger encoding activation of NMDA receptors in hippocampus

    Margarita C Dinamarca et al.
    A protein called RNF10 relays messages from synapses to neuron cell nuclei, and is responsible for long-lasting modifications of dendritic spines as observed after activation of synaptic glutamate receptors.

    SnRK1-triggered switch of bZIP63 dimerization mediates the low-energy response in plants

    Andrea Mair et al.
    The transcription factor bZIP63 is a key regulator of the starvation response in the model plant Arabidopsis thaliana and is directly targeted by the kinase SnRK1.
