Abstract:
The history of glucocorticoid hormone research is an excellent example of "bedside to bench" investigation. It started with two very insightful clinical observations. Thomas Addison described the syndrome of what came to be known as adrenal hormone insufficiency and Harvey Cushing the syndrome of glucocorticoid hormone excess. These dramatic and life-threatening conditions spawned 150 years of active research that has involved many disciplines; indeed some of the fundamental observations of molecular biology are the result of this work. We have a fundamental knowledge of how glucocorticoids regulate gene transcription, their major effect. The challenge facing current and future investigators is to discern how to use this information to make these powerful therapeutic agents safer and more effective.

Regulation of Metabolism
Target Cell Response to Hormones
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...
Hormones of the Adrenal Glands
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and...
