Figure 7. SREBP-1a promoter is activated by Sp1 in SL2 cells.

Drosophila SL2 cells were used in a transfection assay along with the indicated SREBP-1a promoter plasmids. Where indicated, an expression vector for pPACSp1 was also included at either 100 or 300 ng. A control pPAC-β-gal plasmid was co-transfected in all samples as a control. Each construct was analysed in triplicate and the luciferase values were normalized to β-gal and plotted as indicated on the x-axis.
