Figure 2. Regulation of the LAIR-1 basic promoter by ETS-1 and ETS-2. Expression vector of ETS-1 (pcDNA-ETS1) or ETS-2 (pSPORT-ETS2) was co-transfected into HEK297T cells with pGL-lair1-p6 (-256/-8), pGL-lair1-p8 (-93/-8), pGL-lair1-p9 (-43/-8), or pGL-lair1-p10 (-162/-92). Luciferase activities were measured at 48 h after transfection. The bars represent the mean ± standard deviation of three independent transfection experiments.
