Abstract Objective: Excess dietary salt increases vascular stiffness in humans, especially in salt-sensitive populations. While we recently suggested that the endothelial sodium channel (EnNaC) contributes to salt-sensitivity related endothelial cell (EC) and arterial stiffening, mechanistic understanding is incomplete. This study thus aimed to explore the role of EC-serum and glucocorticoid regulated kinase 1 (SGK1), as a regulator of sodium channels, in EC and arterial stiffening.
