| Outline of Final Research Achievements |
Dietary potassium intake is inversely related to blood pressure and mortality. Moreover, the sodium-chloride cotransporter (NCC) plays an important role in blood pressure regulation and urinary potassium excretion in response to potassium intake. We investigated how potassium regulates NCC activity, and clarified molecular mechanism of NCC regulation by potassium. We found that lower intracellular chloride concentration via ClC-K channel activated NCC, when K intake is low. On the other hand, when K intake is high, calcineurin is activated and suppressed NCC. These molecular mechanism regulates potassium-related hypertension.
