Abstract: Objective To investigate the regulatory functions of human tyrosine hydroxylase gene upstream region. Methods A human TH gene upstream fragment was amplified by PCR, and was inserted into plasmid pGL3-Basic, to build a luciferase reporter vector. The reporter vector was transient transfected into MES23.5, 293T and Cos7 cells, and the promoter activity was mensurated using Dual Luciferase Assay system. Results Length of the isolated DNA fragment is 520 bp, which located at -495/+25 region of the human tyrosine hydroxylase gene. By comparison with pGL3-Basic vector, the recombinant reporter vector could significantly expressed luciferase in three types of cells(P<0.01). Conclusion TH gene -493/+27 region possesses promoter activity, and the constructed reporter gene will help us study the regulation of TH gene expression.
