Potassium-Alkali-Enriched Diet, Hypertension, and Proteinuria following Uninephrectomy.

The K-alkali-enriched diet blunted post-uninephrectomy hypertension and facilitated acid clearance by suppressing proximal Na+ transporters and increasing K+ -alkali secretion. Further, uninephrectomy associated proteinuria could be attributed, at least in part, to elevated SNGFR coupled to downregulation of megalin which reduced fractional protein endocytosis and Vmax.
