Abstract/OtherAbstract:
The uptake and intracellular accumulation of an amino acid mixture by incubated Ehrlich ascites tumour cells was studied. The composition of the amino acid mixture simulated that of mouse intraperitoneal fluid and amino acid uptake was studied over a range of concentrations between 0.0 (no added amino acids) and 10.0-times intraperitoneal concentrations. For most amino acids uptake into cells and intracellular accumulation occurred as concentrations were increased up to 6.0-times the intraperitoneal concentrations; further increases in external amino acid concentrations did not increase concomitantly with intracellular concentrations. These data, when analysed indicated a net protein synthetic rate of 20% d-1 and that the rate of protein synthesis may be limited by the availability of the amino acids lysine, threonine and methionine.
