Species or TestSystem (Pharmacological Data)
caudate of rat
Method (Pharmacological Data)
Example 4 - DA, NE, 5-HT Release AssaysA series of compounds were assayed for release of dopamine, serotonin, and norepinephrine as well as for activity at the 5-HT2B receptor. This data is shown below in Table 3.DA, NE and 5-HT Release Assays[3H]MPP+ was used as the
radioligand for both the DA and NE release assays, because this method led to an improved signal-to-noise ratio. Rat caudate (for DA release) or whole brain minus cerebellum and caudate (for NE and 5-HT release), was homogenized in ice-cold 10percent sucrose containing 1 μΜ reserpine. Nomifensine (100 nM) and GBR12935 (100 nM) were added to the sucrose solution for [3H]5-HT release experiments to block any potential [3H]5-HT reuptake into NE and DA nerve terminals. For the DA release assay, 100 nM desipramine and 100 nM citalopram were added to block [3H]MPP+ uptake into NE and 5-HT nerves. For the NE release assay, 50 nMGBR12935 and 100 nM citalopram were added to block [3H]MPP+ uptake into DA and 5-HT nerves. After 12 strokes with a Potter-Elvehjem homogenizer, homogenates were centrifuged at 1000 x g for 10 min at 0^1 °C and the supernatants were retained on ice (synaptosomal preparation).Synaptosomal preparations were incubated to steady state with 5 nM [3H]MPP+ (60 min) or 5 nM [3H]5-HT (60 min) in Krebsphosphate buffer (without BSA) (pH 7.4), which contained 154.4 mM aCl, 2.9 mM KC1, 1.1 mM CaCl2, 0.83 mM MgCl2, 5 mM glucose, 1 mg/mL ascorbic acid, 50 μΜ pargyline plus 1 μΜ reserpine in a polypropylene beaker with stirring at 25 °C with the appropriate blockers. After incubation to steady state, 850 μ of synaptosomes preloaded with [3H]ligand were added to 12 x 75 mm polystyrene test tubes that contained 150 μ test drug in uptake buffer plus 1 mg/ml BSA. After 5 min (3H]5-HT) or 30 min (NE and DA assays) the release reaction was terminated by dilution with 4 ml wash buffer (10 mM Tris-HCl pH 7.4 containing 0.9percent NaCl at 25 °C) followed by rapid vacuum filtration over Whatman GF/B filters using a Brandel Harvester. The filters were rinsed twice with 4 ml wash buffer using the Brandel Harvester, and the retained tritium was counted by a Taurus liquid scintillation counter at 40percent efficiency after an overnight extraction in 3 ml Cytoscint (ICN).Substrate Reversal ExperimentsFor substrate reversal experiments, test drugs were tested at approximately EDgo doses in the absence and presence of blockers (250 nM GBR1209 for DAT, 166 nM desipramine for NET, 100 nM fluoxetine for SERT). Substrate activity was detected by a significant reversal of the releasing effect of the test drug.Data analysis and statisticsAs previously described (Rothman RB, Baumann MH, Dersch CM, Romero DV, Rice KC, Carroll FI and Partilla JS Synapse 39: 32-41 (2001), incorporated herein by reference), EC50 values were determined using the nonlinear least squares curve fitting program MLAB-PC (Civilized Software, Bethesda, MD). In substrate reversal experiments, statistical significance was determined using the Student's t-test.
