| Abstract |
|
Circadian clocks align behavioral and biochemical processes with the day/night cycle. Nearly all vertebrate cells possess self-sustained clocks that couple endogenous rhythms with changes in cellular environment. Genetic disruption of clock genes in mice perturbs metabolic functions of specific tissues at distinct phases of the sleep/wake cycle. Circadian desynchrony, a characteristic of shift work and sleep disruption in humans, also leads to metabolic pathologies. Here, we review advances in understanding the interrelationship among circadian disruption, sleep deprivation, obesity, and diabetes and implications for rational therapeutics for these conditions.

| Notes |
The clock coordinates appropriate metabolic responses within peripheral tissues with the light-dark cycle. For example, the liver clock promotes gluconeogenesis and glycogenolysis during the sleep/fasting period, while it promotes glycogen and cholesterol synthesis during the wake/feeding period. Proper functioning of peripheral clocks keeps metabolic processes in sync with the environment, which is critical for maintaining health of the organism. Different tissues exhibit distinct clock-controlled properties thus ablation of the clock in certain tissues will cause opposing effects on metabolic function as uncovered through dynamic challenges at different times in the cycle under different nutrient conditions. Aging, diet, and environmental disruption such as shift-work may also impact the integration of circadian and metabolic systems. Added by: Dr. Enrique Feoli Last edited by: Dr. Enrique Feoli |
