Ammonia Production and Secretion by the Proximal Tubule

American Journal of Kidney Diseases, 1989
Ammonia production and secretion by the proximal tubule accounts for most of the ammonia that appears in the urine. Rates of ammonia production and net luminal ammonia secretion were measured in isolated perfused mouse proximal tubule segments. This approach combines the in vitro microperfusion technique with a sensitive bioluminescence assay for total

Primary Kidney Proximal Tubule Cells

2004
Primary rabbit kidney epithelial cell cultures can be obtained that express renal proximal tubule functions. Toward these ends, renal proximal tubules are purified from the rabbit kidney by the method of Brendel and Meezan. To summarize, each kidney is perfused with iron oxide, which becomes associated with glomeruli.

REGULATION OF PROXIMAL TUBULE FUNCTION BY ANGIOTENSIN

Clinical and Experimental Pharmacology and Physiology, 1992
SUMMARY1. Independent of its effects on renal haemodynamics and glomerular filtration, angiotensin II (All) has direct actions on the proximal tubule involving transepithelial Na+, H+, HCO3‐, and water reabsorption, ammoniagenesis, gluconeogenesis and renal growth.2.

Water permeability and pathways in the proximal tubule

American Journal of Physiology-Renal Physiology, 1983
The route of water transport in the proximal tubule could be either transjunctional or transcellular. A transjunctional route is supported by data showing high osmotic-to-diffusive water permeability ratios, the possible correlation of junctional leakiness to ions and nonelectrolytes with water permeability, and solvent drag of nonelectrolytes and ...

Interactions of vitamin D and the proximal tubule

Pediatric Nephrology, 2015
Severe vitamin D deficiency (reduction in serum 25(OH)D concentration) in infants and children can cause features of the Fanconi syndrome, including phosphaturia, glycosuria, aminoaciduria, and renal tubular acidosis. This indicates that vitamin D and its metabolites influence proximal tubule function.
