Systemic and cellular reflections on ageing and the circadian oscillator: a mini-review

Gerontology. 2011;57(5):427-34. doi: 10.1159/000320673. Epub 2010 Oct 28.


From circulation to digestion to excretion, a circadian clock synchronizes most aspects of mammalian physiology with the solar day. During normal ageing, this daily coordination gradually erodes, and during pathological ageing such erosion is exacerbated. Recent experiments suggest that therapies aimed at sustaining circadian function increase quality of life in elderly patients. Hence, a better understanding of the interactions between the circadian clock and ageing - at both cellular and systemic levels - could lead to direct benefits for aged individuals.
