Hormonal Signaling Cascades

Meaning

Hormonal Signaling Cascades describe the sequential series of intracellular biochemical reactions initiated when a hormone binds to its specific receptor on or within a target cell. This intricate process serves to dramatically amplify the initial hormonal signal, effectively translating it into a specific, measurable cellular response, such as gene expression, enzyme activation, or cell division. These cascades are fundamental to the action of all peptide and amine hormones, providing the essential mechanism for systemic hormonal regulation to control cellular function.
