To determine the transactivation potential of each of the four Ahr Sp1 sites , we fused the Ahr promoter to a luciferase ( LUC ) reporter gene and transfected the construct into the Drosophila cell line Schneider - 2 , which contains no Sp1 or Sp1 - like factors .
 GENE: Ahr; GENE: Sp1 sites; GENE: Ahr promoter; GENE: luciferase; GENE: LUC; GENE: Sp1; GENE: Sp1 - like factors
