Gene Expression Activation

Meaning

Gene Expression Activation is the molecular process by which information encoded in a gene is used to synthesize a functional gene product, typically a protein or a functional RNA molecule. In endocrinology, this process is frequently initiated by hormone binding to intracellular receptors, which then act as transcription factors to regulate specific target genes. Activation leads to changes in cellular function, such as increased enzyme production, altered receptor density, or the synthesis of structural proteins. The precise control of gene activation is fundamental to all adaptive physiological responses, including those related to growth, metabolism, and stress management.
