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.

Development of a microphysiological model of human kidney proximal tubule function

open access: yesKidney International, 2016
The kidney proximal tubule is the primary site in the nephron for excretion of waste products through a combination of active uptake and secretory processes, and is also a primary target of drug-induced nephrotoxicity.

3D Proximal Tubule Tissues Recapitulate Key Aspects of Renal Physiology to Enable Nephrotoxicity Testing

open access: yesFrontiers in Physiology, 2017
Due to its exposure to high concentrations of xenobiotics, the kidney proximal tubule is a primary site of nephrotoxicity and resulting attrition in the drug development pipeline.

Disorders of the Renal Proximal Tubule

Nephron Physiology, 2010
Following glomerular filtration, the bulk of solutes are reabsorbed in the proximal tubule to prevent excessive losses of vital metabolites. In this nephron segment, reabsorption is largely active via dedicated transporters. Hereditary defects in proximal tubular function are characterized by malabsorption affecting amino acids, glucose, potassium ...

The Renal Proximal Tubule

1979
Methodologic as well as conceptual progress during the past decade has made it possible for renal physiologists to “peek” inside the epithelial “black box” of renal tubular function with a greater degree of confidence than ever before. Among the more important developments have been: (1) evolution of the fluid mosaic model of plasma membrane structure (

Endocytic Receptors in the Renal Proximal Tubule

Physiology, 2012
Protein reabsorption is a predominant feature of the renal proximal tubule. Animal studies show that the ability to rescue plasma proteins relies on the endocytic receptors megalin and cubilin. Recently, studies of patients with syndromes caused by dysfunctional receptors have supported the importance of these for protein clearance of human ...

Oxalate secretion in the rat proximal tubule

American Journal of Physiology-Renal Physiology, 1981
Simultaneous capillary and luminal microperfusion studies in the proximal convoluted tubule of the rat were performed to examine the transepithelial secretory flux of [14C]oxalate. Increases in the concentration of oxalate in the capillary solution from 0.096 to 4.3 mM resulted in progressively higher rates of oxalate secretion into the lumen. Further
