  • Title: Selective inhibition of glucose oxidation by triethyltin in rat brain in vivo.
    Author: Cremer JE.
    Journal: Biochem J; 1970 Aug; 119(1):95-102. PubMed ID: 5485756.
    Abstract:
    Results are reported of a comparative study in vivo of the metabolism of [2-(14)C]-glucose and [1-(14)C]acetate in brains of rats intoxicated with triethyltin sulphate. The incorporation of (14)C from glucose into glutamate, glutamine, gamma-aminobutyrate and aspartate was greatly decreased. The incorporation of (14)C from acetate into these amino acids was unaffected. The experimental data indicated that the main action of triethyltin was to decrease the rate at which pyruvate formed from glucose is oxidized. Glycolysis was not inhibited. Changes in glucose metabolism in the brain are shown not to be directly due to hypothermia. Some of the advantages of measuring the labelling of intermediates at very short time intervals after the injection of the labelled glucose are demonstrated.
