Factors controlling the uptake and retention of methionine and ethionine by Ehrlich ascites carcinoma cells.
In a previous study (l), nn-methionine was shown to be a competitive inhibitor of the uptake of glycine by Ehrlich ascites cells. The results obtained, however, could not give any indication as to whether glycine and methionine are transported by the same or different systems. This problem has recently been the object of further consideration by Paine and Heinz (a), who were also unable to prov...
متن کاملUptake of Free Fatty Acids by Ehrlich Ascites Tumor Cells.
Plasma free fatty acid is the form in which fat is transported from the adipose tissue for utilization (2). Almost all of the FFAI present in plasma is tightly bound in a noncovalent complex with albumin, and less than 0.01 y0 is present unbound (i.e. in free solution) under ordinary conditions (3). However, in spite of the high association constants for binding of FFA to albumin, FFA leave the...
متن کاملInhibition of nucleoside uptake into Ehrlich ascites carcinoma cells by new cytostatic methylhydrazones.
For the purpose of studying the structure-activity relationships of N'-methyl-N'-beta-chloroethylbenzaldehyde hydrazones, new hydrazones were synthesized in which the beta-chloroethyl group was replaced by substituents conveying a partial positive charge at the N' moiety by induction and/or mesomerism. In a preliminary antitumor evaluation, some of these hydrazones showed a cytostatic activity ...
متن کامل"-['he Role of Phospholipides in the Uptake of Amino Acids by Ehrlich Ascites Carcinoma Cells*
The phospholipides of Ehrlich ascites carcinoma of the mouse are capable of rapidly incorporating amino acids following in vivo or in vitro incubation of the cells with the labeled compounds. Glucose (0.005 M) stimulated the in vitro uptake of leucine and alanine by the phospholipides of the ascites cells. The amino acids appeared to be readily liberated by the phospholipides into the amino aci...
