Genetic Expression Latency

Meaning

Genetic expression latency refers to the time delay between the initiation of a biological stimulus, such as a dietary change or a resistance training session, and the observable, downstream change in the expression of specific genes and subsequent protein synthesis. This latency period, which can range from hours to weeks, is a crucial consideration in clinical practice because it means that therapeutic interventions require sustained effort before measurable physiological adaptations occur. Understanding this delay manages patient expectations and informs the appropriate frequency of intervention and re-evaluation.
