Sodium-hydrogen exchangers (NHE) are among the main regulators of cell volume and intracellular concentration of hydrogen and sodium ions. By indirectly affecting sodium/calcium exchange across the plasma membrane, NHE can also influence the intracellular concentration of calcium. Excess activation of

Dietary potassium loading results in rapid kaliuresis, natriuresis, and diuresis associated with reduced phosphorylation (p) of the distal tubule Na(+)-Cl(-) cotransporter (NCC). Decreased NCC-p inhibits NCC-mediated Na(+) reabsorption and shifts Na(+) downstream for reabsorption by epithelial Na(+) channels (ENaC), which
