unc-62 and vab-3 dopaminergic-specific RNAi induce defects in endogenous dat-1 and cat-2 gene expression maintenance. (A,B) Endogenous dat-1 and cat-2 dopamine pathway gene reporter expression analysis in animals expressing unc-62 and vab-3 double-stranded RNA under the dopaminergic-specific promoter dat-1. Reporter expression quantification and representative micrographs of each genotype are shown. n > 50 animals each condition; (*) P < 0.05 compared to wild type, Fisher's exact test. Scale: 25 µm.
