the acceleration of the cpe seen in tpa-treated ad5-infected cells was not caused by tpa induction of the protease plasminogen activator , since the protease inhibitors leupeptin and antipain do not inhibit the earlier onset of this cpe and , in contrast , epidermal growth factor , which induces plasminogen activator in hela cells , does not induce an earlier cpe .
