    β3-Adrenoceptor redistribution impairs NO/cGMP/PDE2 signalling in failing cardiomyocytes

    Sophie Schobesberger et al.
    β3-AR signalling via cGMP in cardiomyocytes is regulated via phosphodiesterase 2 and 5 degradation, it is potentially cardioprotective, but dysregulated in heart failure through signal redistribution and higher phosphodiesterase activity.

    Separable gain control of ongoing and evoked activity in the visual cortex by serotonergic input

    Zohre Azimi et al.
    Serotonergic input to visual cortex controls ongoing and evoked activity in a separable manner via distinct receptor pathways.

    Structural color in Junonia butterflies evolves by tuning scale lamina thickness

    Rachel C Thayer et al.
    Artificial selection on wing color and CRISPR/Cas9 knockout of the optix gene both alter scale lamina thickness in Junonia coenia, which shifts structural color wavelength and mimics macroevolutionary butterfly diversity.

    The skin microbiome facilitates adaptive tetrodotoxin production in poisonous newts

    Patric M Vaelli et al.
    Skin-associated bacteria underlie the production of a potent defensive neurotoxin in newts, impacting host physiology, molecular evolution, and predator-prey interactions in a coevolutionary arms race.

    Diminished responses to bodily threat and blunted interoception in suicide attempters

    Danielle C DeVille et al.
    People who have attempted suicide exhibit blunted sensory processing during breathing and pain perturbations, as well as lower heartbeat perception accuracy and reduced mid/posterior insula activity during interoceptive attention.

    Reversible promoter methylation determines fluctuating expression of acute phase proteins

    Shi-Chao Zhang et al.
    DNA methylation status can be exploited to finely and reversibly tune the expression of highly inducible genes with CpG-poor promoters in response to environmental cues.

    Incomplete vesicular docking limits synaptic strength under high release probability conditions

    Gerardo Malagon et al.
    The probability of occupancy of individual synaptic release sites at rest sets an upper limit to synaptic output when increasing action potential related calcium entry.

    An atypical DYRK kinase connects quorum-sensing with posttranscriptional gene regulation in Trypanosoma brucei

    Mathieu Cayla et al.
    A trypanosome DYRK kinase that exhibits fundamental differences to conventional DYRK family regulation links parasite quorum sensing, signal transduction and developmental gene expression.

    Increase of circulating IGFBP-4 following genotoxic stress and its implication for senescence

    Nicola Alessio et al.
    Protein IGFBP-4 acts as a genotoxic stress mediator that, entering into circulation after its secretion by senescent cells, could promote further senescence phenomena in non-injured cells thus impairing tissues’ homeostasis.

    Endogenous siRNAs promote proteostasis and longevity in germline-less Caenorhabditis elegans

    Moran Cohen-Berkman et al.
    Endo-siRNAs slow down the rate of aging and enable the maintenance of a responsive heat shock response in aging germline-less Caenorhabditis elegans.
