Glucocorticoid remediable aldosteronism also describable as aldosterone synthase hyperactivity, is an autosomal dominant disorder in which the increase in aldosterone secretion produced by ACTH is no longer transient. It is a cause of primary hyperaldosteronism. [1]
Glucocorticoid deficiency can be caused by inherited genetic disorders that affect the production of cortisol in the adrenal glands, such as familial glucocorticoid deficiency (FGD). [3] FGD is a group of monogenic recessive disorders caused by disease-causing variants in genes involved in cortisol biosynthesis. [ 4 ]
The glucocorticoids provide a reliable substitute for cortisol, thereby reducing ACTH levels. Reducing ACTH also reduces the stimulus for continued hyperplasia and overproduction of androgens. In other words, glucocorticoid replacement is the primary method of reducing the excessive adrenal androgen production in both sexes.
The glucocorticoid receptor (GR or GCR) also known as NR3C1 (nuclear receptor subfamily 3, group C, member 1) is the receptor to which cortisol and other glucocorticoids bind. The GR is expressed in almost every cell in the body and regulates genes controlling the development , metabolism , and immune response .
Familial hyperaldosteronism is a group of inherited conditions in which the adrenal glands, which are small glands located on top of each kidney, produce too much of the hormone aldosterone. [1] Excess aldosterone causes the kidneys to retain more salt than normal, which in turn increases the body's fluid levels and causes high blood pressure ...
The dose ratio r is the ratio of the dose of agonist required for half maximal response with the antagonist present divided by the agonist required for half maximal response without antagonist ("control"). In other words, the ratio of the EC50s of the inhibited and un-inhibited curves. Thus, r represents both the strength of an antagonist and ...
The Phase Response Curve operates under the following criteria and must occur to prove that phase resetting is the cause of the behavior: An oscillation must already be occurring before it can reset in its phase. This implies that resetting in response to a stimulus can only occur if the oscillation pre-existed before the reset.
This is significant because glucocorticoid is a regulator of the hypothalamus-pituitary-adrenal axis (HPA) and is known to affect stress response. These stress-related epigenetic changes were accompanied by other characteristics that indicated higher stress and anxiety in these offspring, including increased symptoms of PTSD, greater risk of ...
