Fig. 5. Effect of Pitx3 overexpression on endogenous Ahd2 transcript
levels and other mdDA marker genes. (A) Overexpression of
Pitx3 in MN9D cells leads to an increase of endogenous Ahd2
transcript levels. Expression of Th, Aadc, Vmat2, Snca and
Tbp were unaffected. (B) Densitometer-based quantification
showing the fold change of endogenous transcripts between cells transfected
with empty expression vector (+ Control, white bars) and Pitx3
transfected cells (+ Pitx3, black bars).
