To elucidate the regulation of the human heme oxygenase-1 (hHO-1) gene expression, we assessed approximately 4 kb of the 5'-flanking region of the hHO-1 gene for basal promoter activity and sequenced approximately 2 kb of the 5'-flanking region. A series of deletion mutants of the 5'-flanking region linked to the luciferase gene was constructed. Basal level expression of these constructs was tested in HepG2 human hepatoma cells and HeLa cervical cancer cells. By measuring luciferase activity, which was transiently expressed in the transfected cells, we found a positive regulatory region at position -1976 to -1655 bp. This region functions in HepG2 cells but not in HeLa cells. A negative regulatory region was also found at position -981 to -412 bp that functions in both HepG2 cells and HeLa cells. 相似文献
