Modulation of adrenocortical aldosterone and cortisol synthesis by in vitro oxidized low density lipoprotein

Kopprasch Steffi , Ansurudeen Ishrath , Graessler Juergen , Bornstein Stefan R , Pietzsch Jens

Objectives: Oxidative stress is of critical importance in the pathogenesis of endocrinopathies. Since cholesterol serves as a major source of steroid hormone synthesis we investigated the effect of hypochlorite-modified low density lipoprotein (LDL) on aldosterone and cortisol release from human adrenocortical NCI-H295R cells.Methods: Native LDL obtained from healthy volunteers was oxidized to varying degrees by sodium hypochlorite. The resulting modifie...

Human endothelial cells (HUVECs) potentiate aldosterone secretion from human adrenocortical cells through a PKA independent pathway

Ansurudeen I , Krug AW , Kopprasch S , Ehrhart-Bornstein M , Bornstein SR

The mineralocorticoid hormone aldosterone is secreted by the adrenal cortex. It plays a major role in maintaining water and electrolyte balance and hence blood pressure homeostasis by the kidneys. The aldosterone synthesizing zona glomerulosa of the adrenal cortex is a highly vascularized region. This allows a complex and articulated interaction between the steroidogenic cells and the vascular endothelial cells regulating the hormonal output.In this stud...
