From: Duck hepatitis A virus type 1 mediates cell cycle arrest in the S phase
S phase arrest promotes the replication of DHAV-1. A After 24 h of Thymine treatment of DEFs, the cell cycle profile was analyzed by flow cytometry. B The histograms were analyzed by the ModFit LT program to display the cell cycle distribution. C The viral copies were detected at 2 and 24 hpi in the S phase-synchronized or non-synchronized cells. Differences between 2 groups were analyzed using Student's t-test and considered significant: *P < 0.05; **P < 0.01
