    DNA methylation and gene expression changes derived from assisted reproductive technologies can be decreased by reproductive fluids

    Sebastian Canovas et al.
    Reproductive fluids help the correct establishment of some epigenetic marks and gene expression in preimplantation pig embryos.

    An extensive program of periodic alternative splicing linked to cell cycle progression

    Daniel Dominguez et al.
    Extensive periodic regulation of alternative splicing during the cell cycle in genes is linked to cell cycle functions, and involves an auto-inhibitory mechanism that uses the protein kinase CLK1.

    The Ca2+-activated cation channel TRPM4 is a positive regulator of pressure overload-induced cardiac hypertrophy

    Yang Guo et al.
    The TRPM4 ion channel has been identified as an important component in the causation of mechanical pressure overload-induced pathological left ventricular hypertrophy, which is a powerful predictor of cardiovascular mortality.

    Small conductance Ca2+-activated K+ channels induce the firing pause periods during the activation of Drosophila nociceptive neurons

    Koun Onodera et al.
    Drosophila nociceptive neurons convert high-intensity stimuli into characteristic fluctuations of firing rates, quiescent periods of which are regulated by hyperpolarization through small conductance Ca2+-activated K+ channels.

    Rapid regulation of vesicle priming explains synaptic facilitation despite heterogeneous vesicle:Ca2+ channel distances

    Janus RL Kobbersmed et al.
    Heterogeneous distances between vesicles and Ca2+-channels make synapses prone to short-term depression, however, Ca2+-dependent increases in the number of release-ready vesicles supports facilitation even with broadly distributed vesicle:Ca2+-channel distances.

    Visualization of currents in neural models with similar behavior and different conductance densities

    Leandro M Alonso, Eve Marder
    Visualization methods display the dynamics of the currents in conductance-based model neurons, and show how their contribution changes in response to perturbation.

    A positive feedback loop between Flower and PI(4,5)P2 at periactive zones controls bulk endocytosis in Drosophila

    Tsai-Ning Li et al.
    The interplay between the Flower Ca2+ channel and PI(4,5)P2 spatiotemporally couples synaptic vesicle exocytosis to activity-dependent bulk endocytosis and synaptic vesicle reformation from bulk endosomes.

    Glutamate is required for depression but not potentiation of long-term presynaptic function

    Zahid Padamsey et al.
    Electrophysiological and optical analysis of neurotransmitter release at central synapses reveals that glutamate signalling is not required for the long-term potentiation (LTP) of presynaptic function, and instead only promotes presynaptic long-term depression (LTD).

    Nanodomain coupling explains Ca2+ independence of transmitter release time course at a fast central synapse

    Itaru Arai, Peter Jonas
    Ca2+ channels and release sensors at a fast central synapse are tightly coupled, which minimizes the effect of extracellular Ca2+ concentration on the timing of transmitter release.

    Subdued, a TMEM16 family Ca2+-activated Cl channel in Drosophila melanogaster with an unexpected role in host defense

    Xiu Ming Wong et al.
    A newly characterized calcium-activated chloride channel has been implicated in the immune system of Drosophila, shedding light on an enigmatic family of transmembrane proteins that are ubiquitous in nature.
