Gli1 transactivates the FoxM1 promoter. a Schematic diagram of four potential Gli1 binding sites (BS1, BS2, BS3, and BS4) in the FoxM1 promoter. The 9-base pair sequence of the Gli1 binding site and the sequences of four Gli1 binding sites identified in the FxoM1 promoter are shown. b Chromatin was isolated from HT29 cells, and ChIP assays were performed with goat IgG control, Gli1-specific and Gli2-specific antibodies. DM, DNA marker. c Schematic diagram of a series of FoxM1-luciferase constructs. BS4-Mut, binding site 4 mutation; BS4, binding site 4 deletion. d FoxM1 luciferase constructs, as indicated, were transfected into LoVo cells together with full-length V5-Gli1 plasmid or control vector for 48 h and subjected to a luciferase reporter assay. The results were normalized to the Renilla luciferase activity and are expressed as the fold change in relative luciferase activity compared with the control. Error bars represent the mean and S.D. of three independent experiments. **, p < 0.01
