Gene Expression Regulation Circadian

Meaning

Gene Expression Regulation Circadian refers to the precise, time-of-day-dependent control over the transcription of genes, driven by the body’s internal biological clock, the circadian system. This regulation ensures that cellular processes, from metabolism to cell division, are optimally timed to the 24-hour cycle of light and darkness. A vast network of “clock genes” orchestrates this temporal control, influencing nearly every physiological system in the body. Disruptions to this highly organized regulation are implicated in metabolic disorders, sleep disturbances, and chronic disease risk.
