Figure 3. Chloramphenicol acetyl-transferase (CAT) reporter gene assay.

Figure 3

An estrogen-driven promoter was placed upstream of the CAT gene, as described in Materials and Methods. Cells were treated with vehicle alone (lane 1), IL-1 (lane 2), estradiol (lane 3), and estradiol + IL-1 (lane 4). The fold induction of the CAT gene was measured by densitometry. Error bars = SEM, computed from three independent experiments.
