Abstract

Adenoviruses (Ads) are small DNA tumor viruses that have played a pivotal role in understanding eukaryotic cell biology and viral oncogenesis. Among other cellular pathways, Ad usurps cell cycle progression following infection. Likewise, progression of the viral infection is influenced by the host cell cycle. We describe here methods developed for synchronizing dividing cell populations and for analysis of cell cycle synchrony by flow cytometry. Furthermore, three methods used to evaluate the outcome of Ad infection in synchronized cell populations are described. These include two assays for infectious centers and an assay for analyzing production of progeny virus by transmission electron microscopy. These methods have been used to demonstrate that Ads that fail to direct synthesis of the E1B 55-kDa or E4orf6 proteins replicate most effectively upon infecting cells in S phase.
