| Research Abstract |
Crigler-Najjar syndrome typel is a hereditary disease which is caused by the defect of bilirubin UDP-glucuronosyl transferase (UDPGT) gene. We have tried the gene therapy for the Crigler-Najjar syndrome typel using a model animal, Gunn rat. Recently, it was reported that Baclrovirus specifically infects human liver cells. To apply the baculovirus system to the gene therapy, we firstly constructed the expression vector of bilirubin UDPGT cDNA and transfected to Sf9 insectcells.We could detect the bilirubin UDPGT band expressed in Sf9 cells by Western blotting. We cloud also detect high bilirubin UDPGT activity by the method of thin layr chromatography. Next we constructed a expression vector having alpha1-antitrypsin promoter which specifically works in liver cells. Now we are transfecting the expression vector to HepG2 or Huh7 cells to conferm the availability of the vector in liver cells. We have analyzed the promoter region by constructing thedeletion series of the region in detail. We clarified that HNF-1 and APS elements are essential to the expression of the bilirubin UDPGT gene.
