    Spatiotemporal regulation of autophagy during Caenorhabditis elegans aging

    Jessica T Chang et al.
    Autophagic flux assays in the nematode Caenorhabditis elegans suggest that autophagy decreases during normal aging, whereas long-lived daf-2 and glp-1 mutants maintain autophagic capacity in distinct spatiotemporal-specific manners to extend lifespan.

    Protein biogenesis machinery is a driver of replicative aging in yeast

    Georges E Janssens et al.
    A comprehensive mapping of the proteome and transcriptome during the complete replicative lifespan of budding yeast predicted an increased abundance of the protein biogenesis machinery is most causal for aging.

    Age- and diet-associated metabolome remodeling characterizes the aging process driven by damage accumulation

    Andrei S Avanesov et al.
    Aging is a process characterized by gradual metabolome remodeling, deceleration of the remodeling in late life and under conditions that extend lifespan, and a mortality-associated pattern of cumulative damage.

    Role of SAGA in the asymmetric segregation of DNA circles during yeast ageing

    Annina Denoth-Lippuner et al.
    The SAGA complex binds non-chromosomal DNA circles and prevents their spreading by attaching them to nuclear pores, thereby leading to the concomitant accumulation of DNA circles and pores in ageing yeast mother cells.

    SIR-2.1 integrates metabolic homeostasis with the reproductive neuromuscular excitability in early aging male Caenorhabditis elegans

    Xiaoyan Guo, L René García
    A protein called SIR-2.1 helps to protect worms from the effects of aging by regulating metabolic processes that would otherwise generate damaging reactive oxygen species.

    Epigenetic drift of H3K27me3 in aging links glycolysis to healthy longevity in Drosophila

    Zaijun Ma et al.
    Epigenetic drift of H3K27me3 is one of the molecular mechanisms that contribute to aging, and stimulation of glycolysis promotes metabolic health and longevity.

    Protein aggregates are associated with replicative aging without compromising protein quality control

    Juha Saarikangas, Yves Barral
    The aging lineage of budding yeast is differentiated by an early-appearing protein deposit that promotes protein quality control.

    The insulin/IGF signaling cascade modulates SUMOylation to regulate aging and proteostasis in Caenorhabditis elegans

    Lorna Moll et al.
    By controlling the SUMOylation of the protein CAR-1, the aging-regulating pathways downstream of the Insulin/IGF signaling cascade and of the germ cells of the nematode Caenorhabditis elegans are integrated.

    Longitudinal imaging of Caenorhabditis elegans in a microfabricated device reveals variation in behavioral decline during aging

    Matthew A Churgin et al.
    The WorMotel, a novel microfabricated device for automated longitudinal imaging of aging in large numbers of Caenorhabditis elegans, reveals that long and short lived strains vary in their behavioral decline during aging in a similar way to the long and short lived individuals in a wild type population.
