Silencing (A) Analysis of PKR phosphorylation in HEK293T cells in the
presence of FLAG-tagged mVP35, eVP35, eVP35 R312A, and batVP35 (500 ng). Western
blots were performed for total and phos- phorylated PKR. Three replicates were
performed. E refers to empty vector control. (B) Analysis of miRNA silencing in
HEK293T cells transfected with the indicated reporter, miRNA expression, and
VP35 expression plasmids as indicated. Error bars represent the SEM for
triplicate experiments. VP35 expression was assessed by western blot for the
FLAG epitope tag. Statistical significance was assessed using a one-way ANOVA
and Tukey’s test: ****p < 0.0001. The miR30-Luc luciferase
reporter assay was repeated twice.
