Molecular Pathways

Meaning

Molecular Pathways describe the specific, sequential series of biochemical reactions, protein-protein interactions, and gene expression changes that occur within a cell, ultimately leading to a defined physiological response, such as cellular proliferation, energy production, or hormone synthesis. These pathways act as the fundamental cellular communication networks, translating external stimuli, like the binding of a hormone to its receptor, into functional biological outcomes. Understanding these intricate molecular cascades is essential for precision medicine in endocrinology, allowing clinicians to target specific points of dysfunction, such as impaired insulin signaling or aberrant steroidogenesis, with high specificity. Dysregulation in these pathways is the root cause of many chronic diseases and hormonal imbalances.
