An adeno-associated virus vector-mediated multiple gene transfer for dopamine synthetic enzymes
Objective: To explore a multiple gene transfer approach with separate adeno-associated virus vectors. Methods: The genes of dopamine synthetic enzymes, tyrosine hydroxylasc (TH), GTP cyclohydrolase I (GCH, an enzyme critical for tetrahydrobioptcrin synthesis), and aromatic L-amino acid decarboxylase (AADC), were cotransduced into 293 cells with separate AAV vectors. Expressions of TH, GCH, and AADC were detected by Western blot analysis. L-dopa and dopamine levels in the ceils were assayed by HPLC. Results: TH, GCH, and AADC proteins were effectively cocxpressed in the transduced cells with three separate AAV vectors, AAV-TH, AAV-GCH, and AAV-AADC. Furthermore, the coexpression of these three proteins resulted in an effectively spontaneous dopainc production in the cotransduced cells. Conclusion: The triple transduction of TH, GCH, and AADC genes with separate AAV vectors is effective, which might be important to gene therapy for Parkinson”s disease.
