The uptake of two labeled amino acid was measured simultaneously, in media with different osmolarities and NaCl content, for 20 min. The main figure shows values of the l-[3H]glutamate and [14C]taurine uptake on the same scale, after normalization to the protein content. The levels of both amino acids were adjusted to 2 µM by adding unlabeled l-glutamate or taurine. In the inset, the effect of hypo-osmotic media on [14C]taurine uptake is shown on an expanded scale for clarity. Data are the mean values ± SEM (n=8). *p<0.05, ***p<0.001, “−58 mM NaCl” vs. “Basal”. #p<0.05, ###p<0.001, “−20 mM NaCl” vs. “−58 mM NaCl” (one-way ANOVA with Fisher’s LSD post hoc test).
