Summary Telomere length, a highly heritable trait, is longer in offspring of older fathers. This perplexing feature has been attributed to the longer telomeres in sperm of older men and it might be an ‘epigenetic’ mechanism through which paternal age plays a role in telomere length regulation...
Summary A norepinephrine (NE) deficiency has been observed in aged rats and in patients with Alzheimer's disease and is thought to cause cognitive disorder. Which endogenous factor induces NE depletion, however, is largely unknown. In this study, we investigated the effects of aging‐associated...
Summary The healthspan of mice is enhanced by killing senescent cells using a transgenic suicide gene. Achieving the same using small molecules would have a tremendous impact on quality of life and the burden of age‐related chronic diseases. Here, we describe the rationale for identification...
Summary Muscle aging is associated with changes in myeloid cell phenotype that may influence age‐related changes in muscle structure. We tested whether preventing age‐related reductions in muscle neuronal nitric oxide synthase (nNOS) would obviate age‐related changes in myeloid cells in...
Summary Peroxiredoxins (Prx) are abundant thiol peroxidases with a conserved anti‐ageing role. In contrast to most animals, the nematode worm, Caenorhabditis elegans, encodes a single cytosolic 2‐Cys Prx, PRDX‐2, rendering it an excellent model for examining how peroxiredoxins affect animal...
Summary Current knowledge indicates that the adult mammalian retina lacks regenerative capacity. Here, we show that the adult stem cell marker, leucine‐rich repeat‐containing G‐protein‐coupled receptor 5 (Lgr5), is expressed in the retina of adult mice. Lgr5+ cells are generated at late...
Summary Aging is commonly associated with a structural deterioration of skin that compromises its barrier function, healing, and susceptibility to disease. Several lines of evidence show that these changes are driven largely by impaired tissue mitochondrial metabolism. While exercise is...
Summary Metabolism is closely linked with cellular state and biological processes, but the mechanisms controlling metabolic properties in different contexts remain unclear. Cellular senescence is an irreversible growth arrest induced by various stresses, which exhibits active secretory and...
Summary It is now thought that atherosclerosis, although due to increased plasma lipids, is mainly the consequence of a complicated inflammatory process, with immune responses at the different stages of plaque development. Increasing evidence points to a significant role of Toll‐like receptor 4...
