    The multi-tissue landscape of somatic mtDNA mutations indicates tissue-specific accumulation and removal in aging

    Monica Sanchez-Contreras, Mariya T Sweetwyne ... Scott R Kennedy
    The accumulation of somatic mutations during aging is not uniform across tissue types and, in addition, shows significant variability in the source of mutation that can be modified by small molecule interventions.

    Loss of Mir146b with aging contributes to inflammation and mitochondrial dysfunction in thioglycollate-elicited peritoneal macrophages

    Andrea Santeford, Aaron Y Lee ... Rajendra S Apte
    MicroRNA-146b regulates aging, activation, and mitochodrial function in thioglycollate-elicited peritoneal macrophages.

    High social status males experience accelerated epigenetic aging in wild baboons

    Jordan A Anderson, Rachel A Johnston ... Jenny Tung
    Among the factors that predict fitness in wild baboons, dominance rank in males, but not in females, is the best predictor of epigenetic aging.

    A TORC1-histone axis regulates chromatin organisation and non-canonical induction of autophagy to ameliorate ageing

    Yu-Xuan Lu, Jennifer C Regan ... Linda Partridge
    Modulation of histone levels in gut enterocytes by rapamycin treatment alters chromatin organisation and induces intestinal autophagy through transcriptional regulation to prevent age-related decline in the intestine and extend lifespan.

    Myelin dystrophy impairs signal transmission and working memory in a multiscale model of the aging prefrontal cortex

    Sara Ibañez, Nilapratim Sengupta ... Christina M Weaver
    Biologically plausible levels of myelin dystrophy induce substantial working memory impairment in a computational model of brain aging across two spatial and temporal scales.

    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.

    Structural insights into the activation of human calcium-sensing receptor

    Xiaochen Chen, Lu Wang ... Yong Geng
    The cryo-electron microscopy structures of inactive and active states of calcium-sensing receptor (CaSR) reveal the activation mechanisms of CaSR.

    Male rat leukocyte population dynamics predict a window for intervention in aging

    Hagai Yanai, Christopher Dunn ... Isabel Beerman
    Rat blood profiles support non-linear aging with distinct trajectory shifts, and these profiles could be used to predict non-overt illness in rats or aging intervention efficacy.

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

    Lorna Moll, Noa Roitenberg ... Ehud Cohen
    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.

    Murine muscle stem cell response to perturbations of the neuromuscular junction are attenuated with aging

    Jacqueline A Larouche, Mahir Mohiuddin ... Carlos A Aguilar
    Muscle stem cells locally respond to perturbations of motor neurons and the neuromuscular junction.
