Dietary sodium intake and kidney tubular protein abundance in urinary extracellular vesicles

Background: Dietary sodium intake is a modifiable determinant of blood pressure, and impaired renal sodium handling is implicated in the pathogenesis of hypertension. Whether dietary sodium intake modulates renal tubular sodium transporter abundance among normotensive adults at risk for hypertension is unknown. Methods: Forty-six normotensive adults with normal kidney function at risk of developing hypertension were prospectively enrolled to complete a very low sodium (LS) diet followed by a high sodium (HS) diet. Urinary extracellular vesicle (uEV) proteins were quantified from a 24-hour urin
