Time course of GDNF protein expression in the striatum during a six month period following a single administration of DNPs containing pGDNF_1b (16.0 µg). Animals were euthanized in groups of 5 at each time point and the injected and non-injected striatum were dissected from the brain. In each dissected sample GDNF protein content was determined by ELISA and data are graphed as a percent of baseline; that is, GDNF protein values for the injected side were divided by the values for the non-injected side (baseline). ^p<0.05 vs. Days 98, 130, or 180; #p<0.05 vs. all other days; *p<0.05 vs. Day 130.
