Incorporation by Ehrlich Ascites Cells in Vitro
I t was shown by Crabtree in 19~9 (8) that addition of glucose to tumor slices led to a decrease in their respiratory activity, and this fact has been confirmed (6, 10). The inhibitory effect of glucose on the respiratory activity of ascites cells is much greater and may approach 40 per cent (for reviews of the "Crabtree" or "reversed Pasteur" effect in ascites tumor cells, the recent papers by...
متن کاملOn Perfused Ehrlich Ascites Tumor Cells
In an attempt to overcome resistance of hypoxic cells to radiotherapy, the combination of a hematoporphyrin derivative (Hpd) and 2-deoxy-D-glu'cose (2-DG), a promising radiomodifier, was evaluated by assessing the alterations in phosphorylated metabolites and bioenergetics induced in perfused Ehrlich :lscites tumor (EAT) cells, using Phosphorus31 Magnetic Resonance Spectroscopy (JiP-MRS). By re...
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 کاملPreservation of Ehrlich ascites tumor cells with dimethyl sulfoxide.
For a number of years our investigations of Ehrlich ascites tumor (EAT) in Mus musculus as a model for tumor immunity studies have yielded variable LD50 values. To explain these results, the hypothesis that the cell challenge is modified during transfer of the stock cells from animal to animal is being tested. Our first attempts at freezing a stock cell suspension of EAT in the ascitic fluid or...
متن کاملMechanisms of resistance to daunorubicin in Ehrlich ascites tumor cells.
Uptake and binding of daunorubicin were studied in a sensitive (EHR 2) and in a resistant (EHR 2/DNR+) subline of Ehrlich ascites tumor cells. At steady state, the celhmedium ratio of daunorubicin was about 10-fold higher in EHR 2 than in EHR 2/DNR + . The bindings of daunorubicin to cell homogenate of the two cell lines were equal when the concentration at equilibrium was below 0.7 fig/ml, whe...
