  • Title: Interrelationship of number of glucose carriers and intracellular phosphoribosyl diphosphate level of Ehrlich ascites tumor cells in vitro.
    Author: Choy YM, Lam WP, Fung KP.
    Journal: Cancer Biochem Biophys; 1988 Nov; 10(2):141-7. PubMed ID: 2472871.
    Abstract:
    The intracellular phosphoribosyl diphosphate (prpp) levels of Ehrlich ascites tumor cells increased during glucose supplementation and decreased during glucose deprivation, while the numbers of glucose carriers as determined by glucose-reversible cytochalasin-B binding changed in an opposite manner relating to the extracellular glucose concentrations and the intracellular prpp levels of Ehrlich ascites tumor cells in vitro. Incubation of cells with hypoxanthine or 2,4-dinitrophenol lowered the intracellular prpp levels and resulted in an increase in numbers of glucose carriers.
