FIG. 12.

Activation of RANTES transcription by NF-IL6/C/EBPβ overexpression. A549 cells were cotransfected with 2 μg of pGL2-220 plasmid and either different amounts of the NF-IL6 expression plasmid or 1 μg of empty vector; 48 h later, cells were harvested to measure luciferase and β-galactosidase reporter activities. Data are expressed as mean ± standard deviation of normalized luciferase activity.
