What is the Origin of Metabolic Clock Regulation?

The concept emerged from chronobiology research demonstrating that peripheral tissues possess their own self-sustaining circadian oscillators, distinct yet synchronized by the master clock. The term links the circadian clock mechanism directly to metabolic function, creating a focus on the temporal organization of energy processing. This area of study is critical for understanding the timing of food intake and its impact on health.

What is the Mechanism of Metabolic Clock Regulation?

The master clock in the SCN sends signals that entrain these peripheral metabolic clocks, often through systemic cues like feeding time, body temperature, and the rhythmic secretion of cortisol. At the cellular level, core clock genes rhythmically regulate the expression of key metabolic enzymes and transcription factors, such as PPARs and SREBPs. Maintaining precise synchrony between the central and peripheral clocks is essential for efficient substrate utilization and glucose disposal.

Metabolic Clock Regulation

Meaning

Metabolic Clock Regulation refers to the control and synchronization of the internal, tissue-specific circadian clocks that govern the rhythmic timing of metabolic processes within organs like the liver, pancreas, muscle, and adipose tissue. This regulation ensures that nutrient sensing, glucose homeostasis, lipid metabolism, and energy expenditure are optimally timed to the sleep-wake and feeding-fasting cycles. Disruption of this regulation is a significant contributor to metabolic syndrome and hormonal imbalance.
