Transport and metabolism of thiamine in Ehrlich ascites-carcinoma cells.
1. Aerobic or anaerobic incubation at 37 degrees of Ehrlich ascites-carcinoma cells in Krebs-Ringer bicarbonate medium containing glucose and labelled thiamine results in accumulation in the cell of labelled thiamine, so that the concentration of total labelled thiamine in the cells greatly exceeds (by a factor 7) that in the medium. This concentration ratio is approximately constant for small ...
متن کاملEffect of palmitate, acetate and glucose on glutamine metabolism in Ehrlich ascites tumor cells.
Acetate and the long chain free fatty acid palmitate provoked a decrease in the rates of glutamine utilization and glutamate production in Ehrlich ascites tumor cells incubated with 0.5 mM glutamine. There was a cumulative effect with glucose on glutamine metabolism.
متن کاملEffects of Ehrlich ascites antisera on the biochemical activities of Ehrlich ascites carcinoma cells in vitro.
Anl i-tumor sera are now being extensively used in investigations of the activities of neoplasms (e.g. 4-7, 9-13, 15). I t is already known (7), concerning their effects on the biochemical activities of tumors, that Ehrlich ascites carcinoma cells, treated with their antisera in the presence of comp]ement, lose their capacity to respire in the presence of glucose but not in the presence of succ...
متن کاملNucleic acid metabolism in Ehrlich ascites tumor cells.
The incorporation of P32 into deoxyribonucleic acid (DNA) by Ehrlich ascites tumor cells has been found to be considerably more radioresistant when carried out in vitro than in vivo (6). To study the nature of the in vitro incorporation and explore possible reasons for its radioresistance, we have in vestigated the incorporation of P32 and various C'Mabeled precursors into the nucleic acids of ...
متن کاملInorganic ion concentrations in Ehrlich ascites carcinoma cells and fluid.
The concentrations of sodium, potassium, magnesium, cal cium, chloride, and phosphate were determined in Ehrlich ascites tumor cells and fluid after 5, 7, 9, and 12 days of growth. Material obtained after the 12th day showed peculiar intra cellular ion patterns, presumably related to the near-terminal condition. Material drawn after 5-9 days of growth represented viable cells. The intracellular...
