G10 Induces IFN/IRF3- but not NF-κB-Dependent Transcription in Human Fibroblasts.

<p>(A) Dose-dependent expression of IRF3/IFN-dependent luciferase (LUC) in telomerized human fibroblasts (THF). Values displayed are average fold changes ±SD of quadruplicate measurements of luminescence following 7h exposure to indicated concentration of G10 relative to cells exposed only to 1% DMSO (all samples normalized to 1% DMSO). (B) mRNA transcription of genes dependent on IRF3/IFN following 7h exposure to 100μM G10 or UV-CMV. Indicated values represent average ±SEM mRNA fold change relative to cells exposed to 1% DMSO from duplicate experiments. (C) Induction of NF-κB-dependent LUC signal in THF reporter cells following 7h exposure to 1μg/mL LPS, 160 HA units/mL SeV, 1ng/mL TNFα or indicated concentration of G10. Values displayed are as described in (A). (D) mRNA transcription of of NF-κB-dependent genes following 7h exposure to 100μM G10 or 160 HA units/mL SeV. Indicated values are mRNA fold change relative to cells exposed to 1% DMSO and are representative of duplicate experiments.
