1. ATF4 overexpression preserves parkin protein levels after treatment with dopaminergic neuronal toxins.
ATF4 overexpression preserves parkin protein levels after treatment with dopaminergic neuronal toxins. Neuronal PC12 cells were infected with lentivirus carrying GFP alone (GFP) or GFP and rat ATF4 (ATF4) for 3 d, treated with 100 μm 6-OHDA for 10 h or 1 mm MPP+ for 24 h, and then analyzed by qPCR (A) and Western blotting (B). Blots are representative of experiments performed in triplicate. Blots from the three independent experiments were quantified by densitometry for parkin (C), with values normalized to GAPDH. *p < 0.05, compared with GFP with identical drug treatment, by Student's t test.
