Figure Lengend Snippet: HA injection decreases dopaminergic neurons without affecting β-III Tubulin. (A) Coronal sections of the ventral midbrain from E14 vehicle- and HA-injected rat embryos stained to detect neurons (β-III Tubulin+) and dopaminergic phenotype (TH+); a representative section of a vehicle-injected embryo showing many TH-positive neurons while in a similar midbrain section from a representative HA-injected embryo less TH-positive cells are present. Nuclei were detected with Hoechst. Inner white squares in the merge images represent the higher magnifications shown at the bottom. Scale bars: 150 μm and 50 μm for the low-power and high-power pictures, respectively. (B) β-III Tubulin and TH expression by qRT-PCR from E14 vehicle- and HA-injected embryos, with β-III Tubulin presenting no change, and a significant decrease in TH caused by HA. **p < 0.01. (C) Densitometric analyses of the effect of HA administration on protein levels of β-III Tubulin and diverse factors involved in dopaminergic specification and phenotype. HA injection decreased the protein level of TH, Lmx1a, Lmx1b and Pitx3 in midbrain tissue from E14 HA-injected embryos without affecting the generation of neurons, compared to the vehicle-injected condition. Values were normalized to GAPDH signal. *p < 0.05.

Figure Lengend Snippet: Screening interference plasmids. (A) Cellular fluorescence 48 hours after transient transfection. Green cells indicate successful transfection of the plasmids. Scale bars: 50 μm. (B) Western blots for knockdown validation. The bars represent the ratio of optical density values of Pitx3 to β-actin. There was significant difference between the two groups ( P < 0.01, mean ± SD, n = 3, one-way analysis of variance and the least significant difference test). Control indicates the empty plasmid; Sh-3568, the Pitx3-Sh-3568 plasmid; Sh-3569, the Pitx3-Sh-3569 plasmid; and Sh-3570, the Pitx3-Sh-3570 plasmid, which were all transiently transfected into MES23.5 cells.

Figure Lengend Snippet: Effects of Pitx3 gene interference on glial cell line-derived neurotrophic factor (GDNF) transcriptional activity. GDNF-luciferase represents the cells transfected with the GDNF-luciferase plasmid alone. GDNF-luciferase + Pitx3-Sh-3570 represents the cells cotransfected with Pitx3-Sh-3570 and GDNF-luciferase plasmids. Transcriptional activity of GDNF decreased in the cells cotransfected with Pitx3-Sh-3570 and GDNF-luciferase plasmids; ** P < 0.01, vs . the GDNF-luciferase group (mean ± SD, n ≥ 3, independent sample t -test).
