FIG. 6.

GRE-dependent and C/EBPβ-binding-element-independent augmentation of the activation of AGP-CAT by GR and TIF1β. AGP (WT)-CAT, AGP (CDE mutant)-CAT, or AGP (GRE mutant)-CAT was used as a reporter (see Materials and Methods). In 3.5-cm-diameter petri dishes, BHK cells were cotransfected with one reporter plasmid (1 μg) and 0.5 μg of pRSV-hGR (GR), 5 μg of pcDNA3-TIF1β (TIF1β), or both in the presence or absence of 1 μM dexamethasone (DEX). The fold induction for each experiment is shown. The values are the averages of at least two independent experiments. Error bars indicate standard deviations.
