Promoter activity analysis of the 5′ flanking region of lcMSTN-1 (A) and 2 (B) in CIK cells. The promoterless plasmid, pGL3-Basic, and plasmids containing 5′ flanking fragments were shown on the left. The relative luciferase activities (fold-increase) expressed as mean±SE of three experiments were shown in the right, which was normalized against the activity of the pGL3-Basic plasmid. SE, standard error.
