FIG. 3.
Transient transfection of hpromoter A and hpromoter B constructs into NIH3T3 and Caco-2 cells. The constructs shown in Figure 2 and the empty vector pGL4-17 were transiently transfected into the cells, along with a Renilla control vector. The ratio of firefly to Renilla luciferase was determined for four replicas and fold-change determined relative to the longest constructs, p2178 and p1981. The mean fold-change for three or four independent transfections is shown. The bars are±S.E.M. The asterisks indicate significance (p<0.05) in comparison to the longest construct.
