Rapid mineralocorticoid receptor trafficking
Steroids, 2014The mineralocorticoid receptor (MR) is a ligand-dependent transcription factor that physiologically regulates water-electrolyte homeostasis and controls blood pressure. The MR can also elicit inflammatory and remodeling processes in the cardiovascular system and the kidneys, which require the presence of additional pathological factors like for example

The Multifaceted Mineralocorticoid Receptor
Comprehensive Physiology, 2014AbstractThe primary adrenal cortical steroid hormones, aldosterone, and the glucocorticoids cortisol and corticosterone, act through the structurally similar mineralocorticoid (MR) and glucocorticoid receptors (GRs). Aldosterone is crucial for fluid, electrolyte, and hemodynamic homeostasis and tissue repair; the significantly more abundant ...

Mineralocorticoid receptor antagonists
2023Abstract Hypertension, post-myocardial infarction, and heart failure are the cardiovascular clinical syndromes where mineralocorticoid receptor antagonists (MRAs) have shown a beneficial effect. Most guidelines, while recommending MRAs, do not make a clear recommendation as to which MRAs should be used, how doses should be titrated, or ...

Mineralocorticoid receptors and hypertension
The Journal of Steroid Biochemistry and Molecular Biology, 1995Mineralocorticoid receptors (MR) have equal affinity for the mineralocorticoid aldosterone, and the physiological glucocorticoids cortisol and corticosterone. In epithelial tissues in vivo, MR are protected against glucocorticoid occupancy by the enzyme 11 beta-hydroxysteroid dehydrogenase, allowing access by the lower circulating levels of the ...

Mineralocorticoid receptor antagonists
2022Abstract This chapter studies the use of aldosterone antagonists, also known as mineralocorticoid receptor antagonists (MRAs), in chronic heart failure (CHF). Overall, the results for aldosterone blockade in CHF due to left ventricular systolic dysfunction—now called heart failure with reduced ejection fraction (HFrEF)—have been very ...

Pseudohypoaldosteronism and mineralocorticoid receptor abnormalities
The Journal of Steroid Biochemistry and Molecular Biology, 1991Pseudohypoaldosteronism is a rare inherited disease characterized by renal salt loss, hyperkalemia and metabolic acidosis despite highly elevated aldosterone values. We previously reported absent or reduced numbers of mineralocorticoid receptors in mononuclear leukocytes and defective effector mechanism as shown by no response in vitro to the ...

Nihon rinsho. Japanese journal of clinical medicine, 2009
Recent clinical trials have indicated the utility of mineralocorticoid receptor (MR) antagonists in patients with cardiovascular and renal diseases. Experiments studies have shown that chronic treatment with aldosterone resulted in severe cardiac and renal injuries, which were ameliorated by MR antagonists.

Mineralocorticoid receptor and cardiac arrhythmia
Clinical and Experimental Pharmacology and Physiology, 2013Summary Mineralocorticoid receptor (MR) activation has been shown to play a deleterious role in the development of heart disease in studies using specific MR antagonists (spironolactone, eplerenone) in both experimental models and patients. Pharmacological MR blockade attenuates the transition to heart failure (HF) in models of systolic left ...

Mineralocorticoid Receptors in Human Kidney
The Journal of Clinical Endocrinology & Metabolism, 1976Cytosol binding of [3H]aldosterone was measured after incubation of the hormone at 37 C with slices of human kidney obtained after surgical removal. High affinity [3H]aldosterone binding with an apparent equilibrium dissociation constant (Kd) of approximately 0.5 nM was observed to probably "mineralo-corticoid receptors." [3H]aldosterone binding of ...

Evolution of the Mineralocorticoid Receptor
2019The mineralocorticoid receptor (MR) and its kin, the glucocorticoid receptor (GR) evolved from an ancestral corticoid receptor (CR) in a cyclostome (jawless fish) through gene duplication and divergence. Distinct MR and GR orthologs first appear in cartilaginous fishes, such as sharks, skates, rays and chimaeras.
