    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.

    Haploinsufficiency of Trp53 dramatically extends the lifespan of Sirt6-deficient mice

    Shrestha Ghosh et al.
    The dramatic extension of lifespan in Sirt6-deficient mice by Trp53 haploinsufficiency suggests that SIRT6 has distinct biological function from SIRT1 in regulating p53 activity and preventing cells from senescence/apoptosis.

    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.

    AMPK and vacuole-associated Atg14p orchestrate μ-lipophagy for energy production and long-term survival under glucose starvation

    Arnold Y Seo et al.
    Upon AMPK activation by acute glucose restriction, Atg14p shifts its distribution from ER exit sites to liquid-ordered membrane domains on the vacuolar surface where, together with Atg6p, it facilitates LD-specific autophagy (i.e., microautophagy of lipid droplets) for energy production and long-term survival of starved cells.

    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.

    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.

    The Natural History of Model Organisms: Nothobranchius furzeri, an 'instant' fish from an ephemeral habitat

    Martin Reichard, Matej Polačik
    The turquoise killifish from ephemeral pools in African savannah combines extremely short lifespan with a standard vertebrate body plan – ideal attributes for a laboratory animal.
