The effect of aphidicolin on adenovirus DNA synthesis.
Aphidicolin inhibits adenovirus DNA replication in HeLa cells and in a cell-free, infected, nuclear extract in which viral DNA is elongated. The compound inhibits alpha DNA polymerase, extensively purified from HeLa cells, but has little or no effect on the beta or gamma DNA polymerases similarly purified. Aphidicolin does not affect thymidine uptake by cells nor does synthesis as it also inhibits DNA replication in uninfected cells. The inhibition by aphidicolin is reversible if the drug is removed within 18 hrs after addition to HeLa or Chinese Hamster Ovary cells but the cells are irreversibly affected if the drug remains for 48 hours.
