Multiplication of Influenza Virus in the Presence of Cordycepin, an Inhibitor of Cellular RNA Synthesis

Abstract

Replication of influenza viruses, but not parainfluenza viruses, is sensitive in the early stages to treatment of host cells with actinomycin D and other inhibitors of DNA-dependent RNA synthesis1. Recent evidence suggests that the influenza viruses require host cellular DNA transcription mediated by DNA-dependent RNA polymerase II (nucleo-plasmic) early in the replicative cycle, and this is why they are sensitive to inhibitors of DNA function2. The inability of influenza viruses to grow in cells where DNA-dependent RNA synthesis has been suppressed has seriously hampered studies of the early events in virus RNA synthesis.
