Abstract:Our experiments show Na+-dependent and Na+-independent uptake of glutamine by renal cortical slices. In a Na+-containing buffer, sodium azide stimulates glutamine uptake and ammoniagenesis in slices from normal rats but has no effect on slices from acidotic rats. In Na+-free buffers azide does not alter ammoniagenesis or glutamine uptake by slices from normal rats but decrease both in slices from acidotic rats. Azide decreases ammoniagenesis in mitochondria from norm… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
