Figure 5: Effect of N,N,N,N-tetrakis-(2-pyridylmethyl) ethylenediamine (TPEN) in vivo on the of [3H]taurine transport. Cells (200,00) were preincubated 5 min in Locke buffer at 37°C. The transport was determined at different concentrations of [3H]taurine of 15-105 nM and incubation time of 25 s. The animals were treated with 5 nM of TPEN and the transport was determined 5 days after the administration io. Each value is the mean ± SEM, n = 4. * p < 0.05 with respect to DMSO group.
