FIG. 2.

Transactivation of the pol promoter by IE86 in the permissive U373MG and primary HFF cells. The pol-luciferase (pol-luc) and β-galactosidase reporters were cotransfected with increasing amounts of the RSVIE86 expression vector in permissive U373MG (A) and HFF (B) cells and in nonpermissive HeLa (C) and C33-A (D) cells as indicated. Luciferase activities were normalized to β-galactosidase activity. Units are fold activation. The data represent the results of three independent experiments.
