Effect of modulators of PKA activity on formation of Ad5 infective particles. Effect of modulators of PKA activity on formation of Ad5 infective particles. HeLa cells were infected with Ad (m.o.i. 50) and treated with or without forskolin (20 μM) or H‐89 (20 μM). Forty‐eight hours post‐infection cells were lyzed and the number of infectious Ad particles counted in a plaque assay on 293 cells. The results are presented as relative to the number of plaques obtained from untreated Ad infected cells. Mean values ± SD of four experiments are shown. Giovanni Di Pasquale, and John A.
