Clock Gene Expression

Meaning

The precise and rhythmic process by which specific genes, known as ‘clock genes,’ are transcribed into functional proteins, driving the intrinsic biological timing system of an organism. This expression pattern establishes the circadian rhythm, a roughly 24-hour cycle that governs nearly all physiological processes, including the pulsatile release of hormones and metabolic rate. Disruption of this highly regulated gene expression profoundly impacts endocrine health, sleep quality, and overall longevity.
