FIG. 6

(a) The abundance of total PKR in PKR knockdown and knockout cell lines compared to that in control cells was measured by immunoblot assay. VVΔE3L replication in triplicate wells of (b) PKR knockdown cells or (c) PKR knockout cells was quantified by measuring β-galactosidase activity at 48 hpi as described in Materials and Methods.
