A summary of new findings regarding alterations of magnesium (Mg 2+) and phosphorus (P)
metabolism are reviewed for the clinician caring for patients in general wards. Alterations in …

Renal proximal tubular reabsorption of Pi is a key element in overall Pi homeostasis, and it
involves a secondary active Pi transport mechanism. Among the molecularly identified …

Calcification in necrosis has long been known. Of the tissue components, the cells are most
vulnerable. Nevertheless, little attention has been paid to the role of cell death in …

Renal proximal tubular response to acute administration of a low Pi diet is characterized by
a rapid adaptive increase in apical brush border membrane (BBM) Na-Pi cotransport activity …

Filtered inorganic phosphate (Pi) is largely reabsorbed in the proximal tubule. Na-Pi
cotransport, with a stoichiometry of at least 2: 1, mediates uphill transport at the apical …

Renal brush border membrane Na/P i-cotransport: Molecular aspects in PTH-dependent
and dietary regulation. Inorganic phosphate (P i) is reabsorbed in renal proximal tubules in a …

Variations in dietary phosphate (P i) intake in rats lead to alterations of renal P i
reabsorption. These effects are associated with corresponding changes in the abundance of …

Inorganic phosphate (Pi) is reabsorbed mainly in the proximal tubule, by a second active Na-
dependent transport mechanism. Na/Pi cotransport with a stoichiometry exceeding unity …

The initial linear rate of phosphate uptake was analyzed in rat renal brush border membrane
vesicles. An increase in medium pH from 6.0 to 8.0 increased the sodium gradient …

In dietary phosphate (Pi) deprivation and in aging there is an inverse correlation between
renal proximal tubular brush border membrane (BBM) cholesterol (Chol) content, BBM …
