OBJECTIVE Elevated plasma aldosterone concentrations in patients have been linked to a spectrum of cardiovascular diseases. Mineralocorticoid receptor antagonists provide additional benefits in patients with heart failure. However, whether aldosterone and the mineralocorticoid receptor are involved in aortic aneurysm is unknown. APPROACH AND RESULTS We report that administration of deoxycorti...

The authors conducted an experimental study in male human volunteers to examine the effects of a neurokinin type 1 receptor (NK1R) antagonist on aldosterone secretion. findings show presence Substance P (SP)-positive nerve fibres adrenal cortex vicinity aldosterone-producing cells and with role mineralocorticoid synthesis.

Bilateral renal artery stenosis (RAS) causing recurrent hypertensive emergency and pulmonary oedema is difficult to manage. Use of angiotensin converting enzyme inhibitors (ACEi) II receptor blockers (ARB) usually contraindicated. We present a systematic review literature case vignette which highlights the useful properties this mineralocorticoid antagonists (MRAs) in scenario.

The mineralocorticoid receptor (MR) and mineralocorticoids regulate epithelial handling of electrolytes, and induces diverse effects on other tissues. Traditionally, the effects of MR were ascribed to ligand-receptor binding and activation of gene transcription. However, the MR also utilises a number of intracellular signalling cascades, often by transactivating unrelated receptors, to change c...

Since arginine vasopressin may play a role in mineralocorticoid hypertension, we examined the effects of deoxycorticosterone acetate (DOCA)-salt on vasopressin V1 and V2 receptor binding and their second messengers, inositol phosphate and adenylate cyclase, respectively, in liver and kidney to determine whether altered vasopressin receptor binding is pathogenetic in mineralocorticoid hypertensi...
