    Rapamycin rejuvenates oral health in aging mice

    Jonathan Y An, Kristopher A Kerns ... Matt Kaeberlein
    Short-term treatment with rapamycin reverses periodontal bone loss, attenuates inflammation, and remodels the oral microbiome toward a more youthful state.

    Microbiota from young mice counteracts susceptibility to age-related gout through modulating butyric acid levels in aged mice

    Ning Song, Hang Gao ... Wenlong Zhang
    Gut microbiota from young mice can alleviate gout and hyperuricemia in aged mice, further revealing that the metabolic product butyrate derived from the gut microbiota exerts similar therapeutic effects.

    A rat epigenetic clock recapitulates phenotypic aging and co-localizes with heterochromatin

    Morgan Levine, Ross A McDevitt ... Luigi Ferrucci
    The first epigenetic clock for rats was developed and revealed to reflect phenotypic aging and captured the effects of longevity interventions.

    Conservation of oocyte development in germline cysts from Drosophila to mouse

    Allan C Spradling, Wanbao Niu ... Bhawana Maurya
    Early oocyte development takes place in germline cysts and is strikingly conserved from Drosophila to mouse, reflecting common mechanisms that may help reverse aging and specify oocyte and early embryo polarity.
