Effects of Tat on kinetic analysis of [3H]DA uptake. PC12 cells transfected with WT hDAT or Y88F/H547A were preincubated with vehicle or recombinant Tat1–86 (rTat1–86) at room temperature for 20 min followed by [3H]DA application. Data were calculated as mean ± S.E.M. of specific [3H]DA uptake relative to respective controls as 100% for individual experiment (WT hDAT: 1109.30 ± 230.27 dpm and Y88F/H547A: 400.13 ± 81.75 dpm and n = 5/group). *p < 0.05 compared to their respective controls (paired t test).
