ISRE induction by ChX710 is independent of IFN-α/β, STAT1, and STAT2. (a) ISRE-luciferase reporter cells were incubated, at 4x104 cells/well in a 96-well plate, with DMSO alone or increasing concentrations of ChX710 in the presence of both blocking antibodies against IFN-α/β. After 24 hours of incubation, luciferase induction was determined. Experiment was performed in duplicate, and data represent means ± SD. NS indicates non-significant differences as calculated by two-way ANOVA. (b) STAT1, STAT2 or STAT1 and STAT2 were silenced by siRNA transfection in ISRE-luciferase reporter cells. After 48 hours of cultures, cells were stimulated with ChX710. After 24 hours of incubation, luciferase induction was determined. Data represent means ± SD of three independent experiments. NS indicates non-significant differences relative to control siRNA (CT) as calculated by two-way ANOVA.
