Description

Application

Aldosterone has been used:
• as a RPMI-1640 medium supplement for podocyte culture to test its pathogenicity in obesity-related glomerulopathy (ORG)
• in combination with salt to induce renal injury in mice
• to stimulate primary liver sinusoidal endothelial cells (LSECs) and in the generation of hyperaldosteronism model in mice

The d-isomer of aldosterone is considered to be the biologically active isomer.

Packaging

100 mg in poly bottle

5, 25 mg in glass insert

Biochem/physiol Actions

Aldosterone is a biologically active aldosterone isomer; a mineralocorticoid produced by the adrenal cortex. It induces urinary excretion of K+ and renal reabsorption of Na+. It is produced from adrenocorticotropic hormone (ACTH) and is essential for maintaining sodium homeostasis in the distal tubules. Aldosterone binds to the mineralocorticoid receptor and may modulate vascular system and induce kidney damage. It contributes to the progression of chronic kidney disease(CKD). Aldosterone is part of the renin-angiotensin-aldosterone system (RAAS).

Other Notes

Exists as an equilibrium mixture of the aldehyde and the hemiacetal.
