Abstract

Dietary oxalate is an important contributor to the body oxalate pool. So far, oxalate absorption from the gut has been studied using intestinal everted sacs or brush-border membrane vesicles. Oxalate absorption has been shown to be a simple diffusion process, and increases linearly with increases in concentration. No studies are available on oxalate uptake by enterocytes isolated from various heights of the intestinal villus-crypt axis. In order to understand the mechanism of oxalate intestinal absorption at a cellular level, oxalate uptake was studied in enterocytes isolated from various heights along the intestinal villus-crypt axis. Enterocytes were isolated sequentially along villus-crypt axis based on the pattern of distribution of sucrase, alkaline phosphatase, and leucine aminopeptidase (1).
