| Research Abstract |
There has been no sufficient data for the expression of bilirubin UDP-glycosyltransfearse gene (UGT1A). So, we fist tried to clarify the regulation of the UGT1A1 expression as a first step of gene therapy, and we analyzed the promoter region (up to-3190) of UGT1A1 by transient transfection assay to identify transcriptionally regulatory sequences and found two elements ; one was between-1362 and-1220 and the other between-113 and-70. The proximal one (PE) consisted of two elements, E-box (-104 to-95) and HNF-1 site (-91 to-79). Distal element had sequences similar to those of AP-1 and CREB,but we could not demonstrate the bindings of the factors to DE by gel mobility-shift assay.
