Effect of all-trans retinoic acid (ATRA) in the activity of MSRA promoters. D407 cells were transfected with constructs of promoter 1(construct 1–2, −1232 to −1) and promoter 2 (construct 2–3, −971 to −1). The cells were treated with ATRA 18 h after transfection and luciferase activity was measure 24 h after ATRA treatment. A. Relative luciferase activity of promoter 1 and 2 constructs after treatment with ATRA. B. Cell viability (cellular dehydrogenase activity) of the cells at the different ATRA concentrations. Data (Mean ± SD of three measurements) are expressed as the fold of luciferase activity related to the activity of non-treated cells.
