    Notes: Summary Plasma membrane redox systems seem to play a role in the control of cell growth. In fact, we have found that in mammary tumour cell lines the increase in the proliferation rate is accompanied by a decrease in the plasma membrane redox activity. The oxygen consumption rates, the glycolytic fluxes and other bioenergetic parameters have been studied in two cell strains of Ehrlich ascites tumour with different proliferation rates. In the more proliferative Ehrlich cell strain, the decrease in plasma membrane redox system activity is accompanied by decreased oxygen consumption and glycolytic flux and to a generally less energised status.

    Plasma membrane redox systems in tumor cells (1995)
    Springer
    Protoplasma 184 (1995), S. 168-172 
    Details
    ISSN: 1615-6102
    Keywords: Plasma membrane redox ; Ferricyanide reductase ; Ehrlich cells ; Antitumor drugs

    Topics: Biology
    Notes: Summary Plasma membrane redox systems in tumor cells are analyzed, their role in proton flux and tumor cell growth is described, and the modulation of their activity by antitumor drugs and growth factors is presented. As an example of the evolution of studies in the characterization of plasma membrane redox systems in tumor cells, we summarized our own results on the model system Ehrlich ascites carcinoma.

    Glycolysis and glutaminolysis in perifused ehrlich ascites tumour cells (1989)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: A perifusion system was designed in order to study glucose and glutamine metabolism by freshly harvested Ehrlich ascites tumour cells in steady state conditions. Cells were perifused in the presence of 5 mM glucose, 0·5 mM glutamine or 5mM glucose and 0·5 mM glutamine. The results in steady state reveal that both substrates glucose and glutamine are continuously wasted by tumour cells, excreting two moles of lactate per mol of glucose and one mol of glutamate and ammonia per mol of glutamine consumed into the medium. Glutamine consumption in the presence of glucose was higher than with glutamine alone.
