Figure 1. Endogenous chZAP expression was induced by infection of ALV-J.

At 24 h and 48 h post infection with ALV-J, the chZAP mRNA level (A) and protein expression level (B) of infected cells was significantly (*P < 0.05) higher than the uninfected normal control cells. At 72 h post infection, the chZAP level decreased significantly (**P < 0.01). Results shown are mean ± SEM of three independent experiments.
