▪ Abstract Bicarbonate and CO2 comprise the major pH buffer of biological fluids. In the renal
proximal tubule most of the filtered HCO− 3 is reabsorbed by an electrogenic Na/HCO3 …

The human exocrine pancreas consists of 2 main cell types: acinar and ductal cells. These
exocrine cells interact closely to contribute to the secretion of pancreatic juice. The most …

Bicarbonate transporters are the principal regulators of pH in animal cells, and play a vital
role in acid–base movement in the stomach, pancreas, intestine, kidney, reproductive …

We report the cloning, sequence analysis, tissue distribution, functional expression, and
chromosomal localization of the human pancreatic sodium bicarbonate cotransport protein …

Le bicarbonate ne diffuse pas librement au travers des membranes. Cependant, le
bicarbonate doit passer au travers des membranes, car il participe au métabolisme du CO2 …

The sodium bicarbonate cotransporter (NBC1) is essential for bicarbonate transport across
plasma membranes in epithelial and nonepithelial cells. The direction of the NaHCO 3 …

Physiologic and molecular aspects of the Na+: HCO 3-cotransporter in health and disease
processes. Approximately 80% of the filtered load of HCO 3-is reabsorbed in the proximal …

Na-K-ATPase located on the basolateral membrane (BLM) of intestinal epithelial cells
provides a favorable intracellular Na+ gradient to promote all Na dependent co-transport …

The Na+-K+-2Cl− cotransporter (NKCC1) located on the basolateral membrane of intestinal
epithelia has been postulated to be the major basolateral Cl− entry pathway. With targeted …

To further evaluate the mechanisms of oxalate (Ox 2−) transport in the intestine the following
studies were performed using isolated, short-circuited segments of the rabbit distal colon …
