Rous sarcoma virus (RSV) and cytomegalovirus (CMV) promoters were tested for activity in proliferating and nonproliferating (quiescent or senescent) human embryo fibroblasts. These promoters were cloned upstream of the coding sequence for the Tac subunit of the interleukin 2 receptor, and activity was calculated from the fraction of Tac antigen positive cells detected in a coupled transient transfection/magnetic affinity cell sorting assay. Differences in promoter activities are substantial in quiescent cells: the efficiency of the RSV promoter is no greater than background whereas the CMV promoter is equally active in serum concentrations ranging from 0.5 to 20%. While both promoters are functional in growing cells (WI-38 and HeLa), the CMV promoter exhibits twofold greater activity. Surprisingly, in senescent cells both promoters exhibit the same degree of activity.
