Dose dependency of sirna targeting FKBP6 or FKBP8 on HCV replication. a: Effect of FKBP knockdown on HCV replication. Luciferase activity and cell viability were measured in the O replicon cell line transfected with various amounts of sifkbp6 or sifkbp8. The total amount of transfected sirna was adjusted with sicontrol. Transfected cells were harvested at 72 h post-transfection in order to measure luciferase activity and cell viability. The values obtained were standardized with a value of 0 nm (control) and represented as percentages. Asterisks indicate a significant difference from the control value (**: P < 0.01). The data shown in this figure are representative of three independent experiments. b: The amounts of FKBP6 and FKBP8 in knockdwon cells. The amounts of mrnas of FKBP6, FKBP8 and GAPDH were estimated by qrt-pcr.

Huh7OK1 cells (WT) and FKBP6-knockout Huh7OK1 cells (FKBP6KO) were infected with HCVcc at an m.o.i. of 0.5 and then harvested 4 days post-infection. The HCV RNA and GAPDH mrna were estimated by qrt-pcr. The value of HCV RNA was normalized with the value of GAPDH mrna. Asterisks indicate a significant difference of a pair (*: P < 0.05).

HCV replicon cell lines were transfected with sifkbp6 or sicontrol at a final concentration of 10 nm. The resulting cells were incubated for 16 hours and then transfected with 1 µg of the plasmid encoding HA- FKBP6 (WT) or HA-dTPR3 (dtpr). The transfected cells were incubated for 56 h and then harvested in order to estimate luciferase activity and cell viability.
