Functional analysis of the TFAP2A binding sites present in the DCBLD2/ESDN promoter. HeLa cells were transiently transfected with 700 ng of either pGL3-Basic (basic) or pGL3-ESDN-WT (ESDN-WT) or pGL3-ESDN-MUT1 (ESDN-MUT1), pGL3-ESDN-MUT2 (ESDN-MUT2), pGL3-ESDN-MUT3 (ESDN-MUT3), pGL3-ESDN-MUT1,2 (ESDN-MUT1,2), pGL3-ESDN-MUT1,3 (ESDN-MUT1,3), pGL3-ESDN-MUT2,3 (ESDN-MUT2,3), pGL3-ESDN-MUT1,2,3 (ESDN-MUT1,2,3) vectors. pRLTK (Renilla luciferase) vector was transfected as well to evaluate transfection efficiency and perform normalizations. Fold changes were calculated relative to the pGL3-Basic control vector and expressed as Relative Luciferase Units (RLU). Three independent experiments were performed in triplicate and a representative one is shown here. The error bars indicate the Standard Error (SE) of the replicates. * pv < 0.05; ** pv < 0.01. Wild type binding sites = white boxes; Mutated binding sites = black boxes.
