A. This figure shows semiquantitative mRNA levels for D1R in cg2. Notice an increase in all groups when compared to control. Low, medium and high AS groups show 121 ± 1.1, 269 ± 3.3 and 207 ± 1%, respectively considering the control group as 100%. The greatest increase is in the medium AS group. Image B shows mRNA levels for D2R in the same region with 71 ± 2.6, 44 ± 1.8 and 71 ± 0.8% for groups with low, medium and high AS, respectively. Also, notice that the lowest value is for the medium AS group (n = 4 in all groups). All percentages are significantly different when compared to control (one-way ANOVA, Bonferroni post hoc *p < 0.05). At the top of each frame, there is an example of the electrophoresis agarose gel showing the control oligonucleotide (upper band) and the cDNA of D1R's in (A) and D2R's in (B) (lower band).
