Alterations in aldosterone biosynthesis in essential hypertensives.
We studied hypertensives with decreased adrenal responsiveness to infused angiotensin II (AII) to assess their responsiveness to other aldosterone secretagogues, ACTH and potassium, which are thought to stimulate aldosterone synthesis in sites different from one another and from AII. All subjects, following sodium restriction, received an infusion of AII in increasing doses (0.1-3 ng/kg per min...
متن کاملRegulation of Aldosterone Biosynthesis During Sodium Deficiency
The aldosterone response to adreoocorticotropic hormone (ACTH) and angiotensin II (AH) was evaluated in patients with pituitary insufficiency before and after dietary sodium restriction (10 mEq Na+/day for 12 days). On normal sodium intake, plasma aldosterone concentration and plasma cortisol concentration failed to change from control levels in response to a single injection of ACTH or to a co...
متن کاملMacrolides selectively inhibit mutant KCNJ5 potassium channels that cause aldosterone-producing adenoma.
Aldosterone-producing adenomas (APAs) are benign tumors of the adrenal gland that constitutively produce the salt-retaining steroid hormone aldosterone and cause millions of cases of severe hypertension worldwide. Either of 2 somatic mutations in the potassium channel KCNJ5 (G151R and L168R, hereafter referred to as KCNJ5MUT) in adrenocortical cells account for half of APAs worldwide. These mut...
متن کاملHeme availability affects corticosterone and aldosterone biosynthesis in rat adrenal.
In this paper, we studied the effect of heme availability on corticosterone and aldosterone synthesis in rat adrenal. We found that hemin stimulated corticosterone and aldosterone production in adrenal homogenates in a dose-dependent fashion. Hemin administration to rats also provoked an increase in both corticosterone and aldosterone content in adrenal. 3,5-Diethoxycarbonyl-1,4-dihydro-2,4,6-t...
متن کاملInhibition of aldosterone biosynthesis by atriopeptins in rat adrenal cells.
The effect of synthetic atriopeptins on basal and stimulated aldosterone secretion was determined in isolated adrenal glomerulosa cells of the rat. Neither atriopeptin I (1-21) or III (1-24, i.e., the Phe-Arg-Tyr carboxy-terminal extension of atriopeptin I) altered basal aldosterone release. However, if the cells were prepared from adrenals of sodium-depleted rats, the basal aldosterone release...
