Figure 4

Relative luciferase activity following transfection of human 293T cells with reporter plasmids carrying nested deletions of the 5−-flanking region (from 374 nts upstream to 28 nts downstream) of the putative transcriptional start site of EPHX2. The nucleotide sequence of the 5′ ends of the nested deletions are shown in Fig. 3. The results are expressed as the relative luciferase activities (i.e., firefly luciferase activity/control renilla luciferase activity). Error bars indicate the standard deviation of three independent experiments. The number and relative locations of the putative Sp1 binding sites within are shown to the left and bottom, respectively. The arrow indicates the putative transcriptional start site.
