The sodium-bicarbonate cotransporter NBCe2 (slc4a5) expressed in human renal proximal tubules shows increased apical expression under high-salt conditions.

The electrogenic sodium bicarbonate cotransporter (NBCe2) is encoded by SLC4A5, variants of which have been associated with salt sensitivity of blood pressure, which affects 25% of the adult population. NBCe2 is thought to mediate sodium bicarbonate cotransport primarily in the renal collecting duct, but NBCe2 mRNA is also found in the rodent renal proximal tubule (RPT). The protein expression ...

Osmosis in Cortical Collecting Tubules

This paper reports a theoretical analysis of osmotic transients and an experimental evaluation both of rapid time resolution of lumen to bath osmosis and of bidirectional steady-state osmosis in isolated rabbit cortical collecting tubules exposed to antidiuretic hormone (ADH). For the case of a membrane in series with unstirred layers, there may be considerable differences between initial and s...

Endothelin A receptor-like immunoreactivity on the basal infoldings of rat renal tubules and collecting ducts.

We investigated the distribution of endothelin A (ET(A)) receptor-like immunoreactivity in the rat kidney using affinity-purified antibodies against amino acid residues 403-417 of the rat ET(A) receptor modified by the multiple antigen peptide complex system. Western blot analysis using the affinity-purified anti-ET(A) antibody detected bands of approximately 47.3 and 64.5 kDa in the rat kidney...

The single nephron preparation--cortical collecting tubules.

As Dr. Burg has pointed out, the rabbit has practically the only kidney fromi which nephrons can be dissected conveniently. We have dissected collecting tubules from human kidneys recently, but dissection of the rabbit kidney is far easier and the supply of kidneys certainly more dependable. Two points about the renal anatomy in the rabbit need to be emphasized. First of all, the cortical colle...

PLAGL1 protein is differentially expressed in the nephron segments and collecting ducts in human kidney.

INTRODUCTION PLAGL1 (pleiomorphic adenoma gene-like 1) is a C2H2-type zinc finger transcription factor associated with the regulation of cell growth and development. Although PLAGL1 expression in kidney was assessed by biochemical methods, the exact localization of the PLAGL1 protein in human kidney has not yet been described. MATERIAL AND METHODS Macroscopically unchanged specimens of kidney...
