Cationic amino acid transport in the rabbit reticulocyte. Na+-dependent inhibition of Na+-independent transport.

A transport system for cationic amino acids has been described for the rabbit reticulocyte. This system appears neither concentrative nor energy-dependent. At high levels, several neutral amino acids with large apolar side chains inhibit uptake by it; furthermore, the presence of external leucine accelerates lysine exodus from the cell. These effects do not, however, arise from an interaction b...

K+ secretion in the rat kidney: Na+ channel-dependent and -independent mechanisms.

Renal Na(+) and K(+) excretion was measured in rats with varying dietary K(+) intake. The requirement for channel-mediated distal nephron Na(+) reabsorption was assessed by infusing the animals with the K(+)-sparing diuretic amiloride via osmotic minipumps. At infusion rates of 2 nmol/min, the concentration of amiloride in the urine was 38 microM, corresponding to concentrations of 9-23 microM ...

Underexpression of the Na+-dependent neutral amino acid transporter ASCT2 in the spontaneously hypertensive rat kidney.

This study examined the inward transport of l-[(14)C]alanine, an ASCT2 preferential substrate, in monolayers of immortalized renal proximal tubular epithelial (PTE) cells from Wistar-Kyoto (WKY) and spontaneously hypertensive (SHR) rats. The expression of ASCT2 in WKY and SHR PTE cells and kidney cortices from WKY and SHR was also evaluated. l-[(14)C]alanine uptake was highly dependent on extra...

Fructose-induced increases in neonatal rat intestinal fructose transport involve the PI3-kinase/Akt signaling pathway.

Expression of rat glucose transporter-5 (GLUT5) is tightly regulated during development. Expression and activity are low throughout the suckling and weaning stages, but perfusion of the small intestinal lumen with fructose solutions during weaning precociously enhances GLUT5 activity and expression. Little is known, however, about the signal transduction pathways involved in the substrate-induc...

Vasopressin stimulates Na-dependent phosphate transport and calcification in rat aortic smooth muscle cells.

We investigated the effect of arginine vasopressin (AVP) on inorganic phosphate (Pi) transport in A-10 rat aortic vascular smooth muscle cells (VSMCs). AVP time- and dose-dependently stimulated Na-dependent Pi transport in A-10 cells. This stimulatory effect of AVP on Pi transport was markedly suppressed by V1 receptor antagonist. A protein kinase C (PKC) inhibitor calphostin C partially suppre...
