Task3 K(+) channels are highly expressed in the adrenal cortex and contribute to the angiotensin II and K(+) sensitivity of aldosterone-producing glomerulosa cells. Adult Task3(-/-) mice display a partially autonomous aldosterone secretion, subclinical hyperaldosteronism, and salt-sensitive
Prostasin is a glycosylphosphatidylinositol-anchored serine protease that is released in urine and is involved in epithelial Na channel activation. A direct association between urinary prostasin (u-prostasin) concentration and activation of the aldosterone-driven pathway has been suggested; however,
There is increasing evidence which suggests that the adrenal gland contains the renin-angiotensin cycle. The localization of renin has been reported to be mainly in the zona glomerulosa rather than the fasciculata medullary portion. In the present study we have investigated extracts from
A correct diagnosis of primary aldosteronism (PA) requires adrenal venous sampling (AVS) for the classification of subtypes (bilateral hyperplasia, BAH, or adenoma, APA). Since such testing is not easily practicable, appropriate markers for the definition of subtypes are desirable. We hypothesized
Prostasin is a serine protease present in mammalian urine that increases the activity of the epithelial sodium channel (ENaC) when the two are coexpressed in Xenopus oocytes. To determine if aldosterone, one of the principal regulators of urinary Na reabsorption by the distal nephron, affects
BACKGROUND
The plasma renin activity (PRA) assay measures the ability of renin to generate angiotensin I (AngI) from angiotensinogen. It is used to monitor mineralocorticoid therapy and to screen hypertensive individuals for primary aldosteronism (PA).
METHODS
Samples were incubated in the presence
OBJECTIVE
This article summarizes studies that have analyzed sodium transporters in urinary extracellular vesicles (uEVs) in relation to hypertension.
RESULTS
The majority of kidney sodium transporters are detectable in uEVs. Patients with loss or gain of function mutations in sodium transporter
