Circadian Driven Gene Expression

Meaning

The precise, time-of-day dependent regulation of specific genes whose transcription and translation rates are primarily controlled by the internal circadian timing system. This pervasive biological process ensures that a substantial portion of the genome is expressed rhythmically, coordinating cellular function with the environmental light-dark cycle. It is a fundamental aspect of molecular endocrinology and governs the cyclical production of many hormones, enzymes, and receptors across various tissues.
