PMA effect on KT and Vmax values for [3H]DA uptake

KT(μM)Vmax (fmol/sec)Vmax (% Inhibition)
Control2.0  ± 0.466.3  ± 20.5
PMA1.3  ± 0.325.1  ± 12.41-a 69.2  ± 11.3
  • Saturation curves were constructed for [3H]DA uptake as described in “Materials and Methods” in oocytes pretreated with bath-applied 100 nM PMA for 30 min and washed with FRB. Data are mean values ± S.E.M.; four batches of oocytes, three oocytes from each batch.

  • 1-a P < .05, control vs. PMA using one-way repeated measure analyses of variance.
