Figure Lengend Snippet: Cells were transfected with either PKR siRNA or control siRNA, then PKR mRNA was quantified by real-time RT-PCR; PKR was knocked down (A). Cells were transfected with PKR-expression plasmid (pPKR) or control plasmid (pOS8), then subjected to real-time RT-PCR; PKR mRNA was upregulated by pPKR (B). Mean ± SEM of six replicates. **p<0.01. The amount of HCV core protein in JFH1 and H77s cells were measured by ELISA. HCV core protein was stably expressed in both cell types at least three days after transfection with the HCV-RNA (C). The amount of HCV mRNA in JFH1 and H77s cells was measured by real-time RT-PCR. HCV RNA was expressed in both cell types at least three days after transfection with the HCV-RNA (D). Mean ± SEM of four replicates. PKR and phosphorylated PKR protein expression evaluated by Western blotting; results confirmed PKR mRNA data (E).
Article Snippet: Control siRNA was obtained from Cosmo Bio (Tokyo, Japan); c-Fos siRNA and c-Jun si-RNA were obtained from Thermo Fisher Scientific.
