Dose-dependent transactivation of HNF1 on the 9-kb fragment. CHO cells were cotransfected with 5 μg of phPAH9CAT or phPAH1.5CAT and the indicated amount of pBJ5-HNF1. pSV-β-Galactosidase (2 μg) was included in all transfections as an internal control. The total amount of DNA included was kept constant by adjusting the amount of pBJ5 lacking an insert. The data shown are means ± SD (n = 2–6).
