説明

<jats:title>Summary</jats:title><jats:p>Caloric restriction (<jats:styled-content style="fixed-case">CR</jats:styled-content>) and down‐regulation of the insulin/<jats:styled-content style="fixed-case">IGF</jats:styled-content> pathway are the most robust interventions known to increase longevity in lower organisms. However, little is known about the molecular adaptations induced by <jats:styled-content style="fixed-case">CR</jats:styled-content> in humans. Here, we report that long‐term <jats:styled-content style="fixed-case">CR</jats:styled-content> in humans inhibits the <jats:styled-content style="fixed-case">IGF</jats:styled-content>‐1/insulin pathway in skeletal muscle, a key metabolic tissue. We also demonstrate that <jats:styled-content style="fixed-case">CR</jats:styled-content> induces dramatic changes of the skeletal muscle transcriptional profile that resemble those of younger individuals. Finally, in both rats and humans, <jats:styled-content style="fixed-case">CR</jats:styled-content> evoked similar responses in the transcriptional profiles of skeletal muscle. This common signature consisted of three key pathways typically associated with longevity: <jats:styled-content style="fixed-case">IGF</jats:styled-content>‐1/insulin signaling, mitochondrial biogenesis, and inflammation. Furthermore, our data identify promising pathways for therapeutic targets to combat age‐related diseases and promote health in humans.</jats:p>
