    Live-imaging of endothelial Erk activity reveals dynamic and sequential signalling events during regenerative angiogenesis

    Kazuhide S Okuda et al.
    Live-imaging of a transgenic reporter of vascular Erk signalling in zebrafish reveals sequential signalling mechanisms during the initiation of regeneration in wounded blood vessels.

    Live cell imaging of meiosis in Arabidopsis thaliana

    Maria A Prusicki et al.
    Live cell imaging and the in vivo dissection into distinct stages, called landmarks, represents a new methodology for analyzing meiosis in Arabidopsis and likely in other species as well.

    Time line of redox events in aging postmitotic cells

    Nicolas Brandes et al.
    A sudden fall in the levels of the coenzyme NADPH within cells could have a central role in the process of aging.

    Quantitative dissection of transcription in development yields evidence for transcription-factor-driven chromatin accessibility

    Elizabeth Eck et al.
    Confronting different models of chromatin accessibility with temporally resolved transcription profiles favors a scenario where transcription factors actively, rather than passively, drive chromatin from the inaccessible to the accessible state.

    Growth hormone-releasing hormone disruption extends lifespan and regulates response to caloric restriction in mice

    Liou Y Sun et al.
    Mice with a mutation that disrupts the release of growth hormone show greatly increased lifespan, which can be further increased by caloric restriction.

    Live-cell imaging reveals enhancer-dependent Sox2 transcription in the absence of enhancer proximity

    Jeffrey M Alexander et al.
    Sox2 transcription is not correlated with spatial proximity of its essential regulatory enhancer in embryonic stem cells, suggesting gene transcription is not limited to periods of direct enhancer-promoter contact.

    Live-cell single particle imaging reveals the role of RNA polymerase II in histone H2A.Z eviction

    Anand Ranjan et al.
    Histone variant H2A.Z is deposited near transcription start sites by the chromatin remodeler SWR1 and seems to be removed by RNA polymerase II at an early stage of transcription elongation.

    A genome-wide resource for the analysis of protein localisation in Drosophila

    Mihail Sarov et al.
    A large-scale transgenic resource enables live imaging, subcellular localisation and interaction proteomics of specific gene products of interest at all stages of Drosophila development.

    Increased longevity due to sexual activity in mole-rats is associated with transcriptional changes in the HPA stress axis

    Arne Sahm et al.
    The fact that sexual activity/reproduction doubles the lifespan of certain rodent species is most likely linked to critical changes in the regulation of the hypothalamic–pituitary–adrenal stress axis.

    The genetic organization of longitudinal subcortical volumetric change is stable throughout the lifespan

    Anders Martin Fjell et al.
    Volumetric lifespan change in subcortical structures follows fundamental principles of brain development, lifespan continuity, genetic organization, and age-invariant relationships to cognition.
