    Sir2 phosphorylation through cAMP-PKA and CK2 signaling inhibits the lifespan extension activity of Sir2 in yeast

    Woo Kyu Kang et al.
    The deacetylase Sir2 fine-tunes transcription of PMA1 and other aging related genes in a cAMP-PKA and CK2 signaling dependent manner.

    SUMO peptidase ULP-4 regulates mitochondrial UPR-mediated innate immunity and lifespan extension

    Kaiyu Gao et al.
    SUMOylation regulates mitochondrial UPR signaling through modulation of transcription factors DVE-1 and ATFS-1.

    End-of-life targeted degradation of DAF-2 insulin/IGF-1 receptor promotes longevity free from growth-related pathologies

    Richard Venz et al.
    Inducible degradation of the insulin/insulin-like growth factor-1 receptor shows that a doubling in lifespan is possible even at extremely old ages in an organism.

    PGAM5 promotes lasting FoxO activation after developmental mitochondrial stress and extends lifespan in Drosophila

    Martin Borch Jensen et al.
    A signaling pathway involving PGAM5, ASK1 and JNK induces persistent FoxO activation, chaperone expression and lifespan extension following developmental mitochondrial stress, which can be blocked by mTOR signaling through GCN-2.

    Translation attenuation by minocycline enhances longevity and proteostasis in old post-stress-responsive organisms

    Gregory M Solis et al.
    Directly targeting the ribosome to attenuate translation partly mimics the integrated stress response, increasing lifespan and preserving protein folding capacity even in older individuals with dysfunctional stress response signaling.

    Neuronal TORC1 modulates longevity via AMPK and cell nonautonomous regulation of mitochondrial dynamics in C. elegans

    Yue Zhang et al.
    Modulating the nutrient sensor TORC1 only in neurons in C. elegans is sufficient to regulate systemic longevity via inter-tissue signals that remodel mitochondria networks in non neuronal cells.

    Longevity is impacted by growth hormone action during early postnatal period

    Liou Y Sun et al.
    Transient hormonal alterations during early critical developmental periods can have a crucial and long-lasting effect on lifespan in mice.

    Metformin extends C. elegans lifespan through lysosomal pathway

    Jie Chen et al.
    Metformin extends C. elegans lifespan through lysosome-dependent coordination of TORC1 and AMPK pathways.

    Changes in ferrous iron and glutathione promote ferroptosis and frailty in aging Caenorhabditis elegans

    Nicole L Jenkins et al.
    As worms age reduced glutathione together with increased ferrous iron increases frailty and leads to ferroptosis, which is amenable to therapeutic intervention.
