Plasma level of the endogenous sodium pump ligand marinobufagenin is related to the salt-sensitivity in men.
Salt-induced elevation of the endogenous digitalis like sodium pump ligand marinobufagenin (MBG) in the Dahl salt-sensitive rats resulted in elevated blood pressure (BP). Here, we tested, in humans, whether MBG levels are related to ambulatory 24-h BP (ABP), controlled long-term increase of salt-intake induces changes in MBG and any salt-induced change in MBG is related to salt sensitivity.
