FIGURE 3. Mutational analysis of the promoter elements of COX genes.
Relative luciferase activity of wild-type and site-directed mutations of NRF-1 binding sites on all ten nuclear-encoded COX promoters indicates significant reductions in luciferase activity in all mutants. (n = 6 for each construct). *, p < 0.05; **, p < 0.01; ***, p < 0.001.
