Influence of the hCMV enhancer on liver promoter mediated transfection in hepatocellular carcinoma cells. 50,000 HUH7 cells seeded in 24-well plates were transfected with HD-O polyplexes containing the indicated plasmid (1.5 μg plasmid/well) and the luciferase activity per 10,000 cells determined at indicated time points; n = 2. Open symbols: CMV promoter; gray symbols: liver promoter; full symbols: liver promoter plus hCMV enhancer.
