Salt, sodium channels, and SGK1.
The hormone aldosterone increases extracellular fluid volume and blood pressure by activating epithelial Na+ channels (ENaCs). Serum- and glucocorticoid-induced kinase 1 (SGK1) is an aldosterone-stimulated signaling molecule that enhances distal nephron Na+ transport, in part by preventing the internalization of ENaCs from the plasma membrane. In this issue of the JCI, Zhang et al. demonstrate ...
متن کاملEndothelial sodium channels trigger endothelial salt sensitivity with aging.
The epithelial sodium channel is also expressed in vascular endothelium (endothelial sodium channel [EnNaC]). Depending on ambient sodium concentration, EnNaC is associated with mechanical stiffening of the endothelial cell cortex, leading to endothelial dysfunction. Because the incidence of both salt sensitivity and endothelial dysfunction increases with age, we investigated the abundance of E...
متن کاملRole of Sgk1 in salt and potassium homeostasis.
Aldosterone plays a pivotal role in NaCl and K(+) homeostasis by stimulation of Na(+) reabsorption and K(+) secretion in the aldosterone-sensitive distal nephron (ASDN). Recent studies demonstrated that the serum- and glucocorticoid-regulated kinase 1 (Sgk1) is induced by aldosterone in the ASDN and that polymorphisms of the kinase associate with arterial blood pressure in normotensive subjects...
متن کاملAldosterone, SGK1, and ion channels in the kidney
Hyperaldosteronism, a common cause of hypertension, is strongly connected to Na+, K+, and Mg2+ dysregulation. Owing to its steroidal structure, aldosterone is an active transcriptional modifier when bound to the mineralocorticoid receptor (MR) in cells expressing the enzyme 11β-hydroxysteroid dehydrogenase 2, such as those comprising the aldosterone-sensitive distal nephron (ASDN). One such up-...
