Aldosterone

Aldosterone is the primary mineralocorticoid. Aldosterone is a steroid hormone, and it is synthesized and secreted in response to renin-angiotensin system activation (RAS) or high dietary potassium by the zona glomerulosa (ZG) of the adrenal cortex. Aldosterone activity is dependent by the binding and activation of the cytoplasmic/nuclear mineralocorticoid receptor (MR) at cellular level.

How to use

In Vitro:

Aldosterone (1-1000 nM; 24 hours) inhibits interleukin-1β-stimulated nitrite production by vascular smooth muscle cells in a dose-dependent manner.

In Vivo:

Aldosterone (1 mg/Kg+1% NaCl; i.h.; once daily for 3 weeks) significantly increases systolic blood pressure (SBP), diastolic blood pressure (DBP), left ventricular systolic pressure (LVSP) and left ventricular end-diastolic pressure (LVEDP). Aldosterone (0.72 mg/kg/day; 14 days) causes a small increase ( 14 mmHg) in blood pressure in male mice.
