The August 10, 2017 issue of Cell reported an ability for calorie restriction to prevent the impact of aging on circadian rhythms. “The process of aging and circadian rhythms are intimately intertwined, but how peripheral clocks involved in metabolic homeostasis contribute to aging remains unknown,” the authors write in their introductory remarks. For the current investigation, researchers at the University of California, Irvine fed calorie restricted or unrestricted diets to young and old mice. At 6 and 18 months, liver tissue samples were analyzed. Although calorie restriction did not affect the 24-hour cycle of the older group’s circadian-controlled metabolic system, older cells showed signs […]
