Abstract

Summary: We used DNA microarrays to identify panels of transcriptional markers of aging that are differentially expressed in young (5 month) and old (25 month) mice of multiple inbred strains (129sv, BALB/c, CBA, DBA, B6, C3H and B6C3F 1 ). In the heart, age‐related changes of five genes were studied throughout the mouse lifespan: complement component 4, chemokine ligand 14, component of Sp100‐rs, phenylalanine hydroxylase and src family associated phosphoprotein 2. A similar analysis in the brain (cerebellum) involved complement component 1q (alpha polypeptide), complement component 4, P lysozyme structural, glial fibrillary acidic protein and cathepsin S. Caloric restriction (CR) inhibited age‐related expression of these genes in both tissues. Parametric analysis of gene set enrichment identified several biological processes that are induced with aging in multiple mouse strains. We also tested the ability of dietary antioxidants to oppose these transcriptional markers of aging. Lycopene, resveratrol, acetyl‐ l ‐carnitine and tempol were as effective as CR in the heart, and α‐lipoic acid and coenzyme Q 10 were as effective as CR in the cerebellum. These findings suggest that transcriptional biomarkers of aging in mice can be used to estimate the efficacy of aging interventions on a tissue‐specific basis.

  • Caloric restriction prevents many age-dependent gene expression changes in the mouse brain, reduces age-related brain atrophy in rhesus macaques, and has significant beneficial effects on the age-dependent impairment of learning and memory in rodents and humans.

    “It prevents many age-dependent gene expression changes in the mouse brain (8,43), reduces age-related brain atrophy in rhesus macaques (75) and has significant beneficial effects on the age-dependent impairment of learning and memory in rodents (76,77) and humans (78).”

  • Caloric restriction has beneficial effects on the function of the brain and its vulnerability to age-dependent pathology.

    “Caloric restriction has also been widely documented to have beneficial effects on the function of the brain and its vulnerability to age-dependent pathology.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
