(A) Huh7.5.1 cells containing a subgenomic DENV replicon expressing a Renilla luciferase reporter were transduced with the indicated shRNAs for 72 hr prior to luciferase activity measurement (left panel) and immunoblotting (right panel). Values (means ± SD, two independent experiments) are normalized to control cells
(B) DENV replicon cells were treated with the indicated concentrations of OSW-1 (left panel) or AL-9 (right panel) for 24 hr before luciferase activity measurement. Values are means ± SD, two independent experiments.
(C) HeLa cells stably expressing a nontargeting shRNA or three independent OSBP shRNAs were infected with poliovirus (MOI 0.1) 24 hr before measurement of viral titers (left panel), and immunoblotting (right panel). *, P = .004 and **, P< .001 versus nontargeting shRNA.
