[The relationship between the cation and protein content, cationic transport and the rate of protein synthesis detected in cells in the presence and in the absence of ouabain].
The measurements were made of monovalent cation (K+ + Rb+, Na+) and protein contents, of leucin incorporation into the protein (protein synthesis), and of ouabain-sensitive K+ influx during the growth of the Jurkat culture cells in the presence or in the absence of ouabain. All the data were calculated per cell. The time dependences of these parameters are nonlinear [correction of unline] curves. The results of three independent measurements are not reproduced. The problem was to find out an intracellular "main" parameter, so that the dependences between this and the rest of parameters be of line character. It has been found that it is the protein synthesis rate that may be taken as the main parameter, because between the protein synthesis rate and all the other parameters there is the line connection. Comparative results obtained with or without ouabain showed that K+ and Na+ concentrations in the cell were different, although the constants of the rate of protein synthesis were the same. This points to the same type of change of the protein synthesis process in the cells growing with or without ouabain.
