FIG. 4.

Luciferase assays using upstream sequences of UL65, UL75, or UL122 to drive the expression of firefly luciferase. Asterisks in construct designations indicate the presence of a mutated p53 BS in these sequences. Renilla luciferase expression was used as a normalization control, yielding relative light units (RLU) as the dimension on the ordinate. Each bar represents the average from two independent experiments, and error bars represent the minimum and maximum values of the single measurements.
