Circadian Gene Expression

Meaning

Circadian Gene Expression describes the rhythmic, approximately 24-hour cycle of activation and deactivation observed in a specific set of genes, known as clock genes, that orchestrate the body’s internal biological clock. This rhythmic transcription and translation process governs the timing of countless physiological functions, including metabolism, sleep-wake cycles, and the pulsatile release of many critical hormones. Maintaining robust and synchronized circadian gene expression across different tissues is a cornerstone of metabolic and endocrine health. Disruption to this cycle can lead to systemic dysfunction and accelerated aging.
