Resetting the circadian clock leads to well being and increased life span, whereas clock disruption is associated with aging and morbidity. Increased longevity and improved health can be achieved by different feeding regimens that reset circadian rhythms and may lead to better synchrony in metabolism and physiology. This review focuses on recent findings concerning the relationships between circadian rhythms, aging attenuation, and life-span extension in mammals.

Melatonin and Circadian Rhythm: Aging, Cancer, and Mechanism

The clock and melatonin in relation to aging and cancer, which are important aspects of medicine and biochemistry are addressed with emphasis on the unifying theme based on electron transfer-free radicalsoxidative stress.

The circadian clock and pathology of the ageing brain

New data from experiments in model organisms, gene expression studies and clinical trials imply that dysfunctions of the circadian clock contribute to ageing and age-associated pathologies, thereby suggesting a functional link between the circadian Clock andAge-associated decline of brain functions.

Aging and the clock: Perspective from flies to humans

Drosophila melanogaster, as a model for aging and circadian interactions, has the capacity to facilitate the rapid advancement of research in this area and provide mechanistic insights for targeted investigations in mammals.

Circadian clocks, diets and aging

How the regulation of the circadian clocks by feeding/nutrients and regulation of nutrient signaling pathways by the clocks may contribute to the beneficial effects of calorie restriction on metabolism and longevity, and whether the circadian system can be engaged for future medical applications are discussed.

Novel putative mechanisms to link circadian clocks to healthy aging

This review may lead to the design of large-scale interventions to help people stay healthy as they age by adjusting daily activities, such as feeding behavior, and or adaptation to age-related changes in individual circadian rhythms.

Metabolism and the control of circadian rhythms.

A simple model, integrating biochemical, cellular, and physiologic data, is presented to account for the connection of cellular metabolism and circadian rhythm.

Association between mammalian lifespan and circadian free-running period: the circadian resonance hypothesis revisited

It is found that the deviation of tau from 24 h was inversely related to the lifespan in laboratory mouse strains, and in other rodent and primate species, supporting the hypothesis that misalignment of endogenous rhythms and 24 h environmental cycles may be associated with a physiological cost that has an effect on longevity.

Effect of feeding regimens on circadian rhythms: Implications for aging and longevity

The hypothesis that the beneficial effects exerted by these feeding regimens could be mediated, at least in part, through resetting of the circadian clock, thus leading to synchrony in metabolism and physiology is raised.

Circadian clock resetting in the mouse changes with age

The responsiveness of the circadian clock with age is attenuated to some, but not all stimuli, which suggests that not all clock stimuli loose their effectiveness with age, and that it may be possible to compensate for deficits in clock performance by enhancing the strength of those stimulus pathways which are intact.

The Significance of Circadian Organization for Longevity in the Golden Hamster

Longevity in hamsters is decreased with a noninvasive disruption of rhythmicity and is increased in older animals given suprachiasmatic implants that restore higher amplitude rhythms, substantiating the importance of the temporal organization of physiology and behavior provided by the circadian clock to the health and longevity of an organism.

Circadian rhythms from flies to human

The existence of a circadian clock in humans had been postulated for decades, but an understanding of the molecular mechanisms has required the full complement of research tools, and researchers turned to genetically tractable model organisms such as Drosophila.
