Estrogen Receptor Agonist

Meaning

An Estrogen Receptor Agonist is a substance, either endogenous or pharmaceutical, that binds to and activates estrogen receptors (ERs) within cells, thereby mimicking the biological effects of endogenous estrogen. These compounds initiate intracellular signaling pathways that lead to changes in gene expression, influencing a wide range of physiological processes. The clinical utility of these agonists lies in treating conditions associated with estrogen deficiency or modulating specific estrogen-dependent pathways.
