Metabolism and the Circadian Clock Converge

Disruption of the circadian cycle is strongly associated with metabolic imbalance.

• Circadian rhythms are crucial for regulating key physiological functions including sleep, neurotransmitter levels, and metabolism.
• Epidemiological studies indicate a distinct role of circadian rhythm in metabolic processes.
• Night or rotating shift work and rodent models of circadian arrhythmia demonstrate a connection to obesity and metabolic syndrome.
• Genetically engineered mouse models with disrupted circadian rhythms display signs of metabolic syndrome.
• The relationship between circadian clock genes and specific tissue function versus overall rhythmic activities (like eating and sleeping) is a key question in understanding metabolism.
• The circadian clock interacts with various metabolic components, suggesting it plays an essential role in maintaining metabolic balance.
