STING ligands-mediated signaling response in MEFs. (A) Primary MEFs (1 1 x 1 5 cells/well) derived from wild-type (STING +/+ ) or STING-deficient mice 11 12 13 (STING -/- ) were stimulated with 1 µg /ml of canonical 3-5 cyclic-gmp-amp (cgamp) for the times indicated. The expression level of STING, IRF3 phosphorylated at Ser 396 (p-irf3), NFκB p65 phosphorylated at Ser 536 (p-nf-κbp65), NF-κBp65, 14 TBK1 phosphorylated at Ser 172 (p-tbk1), and β-actin was determined by 15 16 17 18 19 2 21 22 immunoblotting. (B) Nuclear translocation of NF-κBp65 is detected by cellular fractionation. STING +/+ and STING -/- MEFs were stimulated with1 µg /ml of dsdna9 for 3 h, and then cells were separated into cytosol and nuclear fractions. Each fraction was concentrated and subjected to immunoblotting with indicated antibodies. (C) STING +/+ and STING -/- MEFs were stimulated with 1 µg /ml of dsdna9, 5 µg /ml of Poly(dA:dT), 5 µg /ml of Poly(I:C), or 2 µm of DMXAA for 6 h, and then total RNA was extracted from these cells, and the expression level of mrna of IFNβ, Ccl5, IL-6 and CXCL1 was determined by qrt-pcr. Data were normalized to
23 24 25 26 27 28 the levels of GAPDH mrna. Error bars indicate the standard deviations (SD). Fig. S2. HSV-1-mediated signaling response in MEFs. (A) Primary MEFs (1 x 1 5 cells/well) derived from wild-type (STING +/+ ) or STING-deficient mice (STING -/- ) were stimulated with 5 µg /ml of dsdna representing the genomes of HSV-1 or purified HSV-1 at an moi of 1 PFU/ml for the times indicated. The expression level of STING, IRF3 phosphorylated at Ser 396 (p-irf3), NFκB p65 phosphorylated at Ser 536 29 3 (p-nf-κbp65), NF-κBp65, TBK1 phosphorylated at Ser 172 β-actin was determined by immunoblotting.

(A) TBK1 +/+ and TBK1 -/- MEFs were stimulated with 1 µg /ml of dsdna9, or 5 µg /ml of Poly(I:C) for the times indicated. The expression level of ERK1/2 phosphorylated at Thr 22 /Tyr 24 (p-erk1/2), ERK1/2, SAPK/JNK phosphorylated at Thr 183 /Tyr 185 (p-sapk/jnk), JNK1/2, p38 phosphorylated at Thr 18 /Tyr 182 (p-p38), p38, and c-jun phosphorylated at Ser 63 (p-cjun) was determined by immunoblotting. (B) 293T cells were transfected with empty vector (EV) and Flag-tagged TBK1 (TBK1-FL) for 24 h, and then cell extracts were subjected to immunoblotting with indiacted antibodies. Fig. S4. IKKi/IKKε and NIK does not involve in the STING-dependent, dsdna-mediated signaling response in MEFs. RNAi in MEFs using the non-specific (NS) and IKKi/IKKε (Α) or NIK (B) were stimulated with 5 µg /ml of dsdna9 for the times indicated. The expression level of STING, IRF3 phosphorylated at Ser 396 43 (p-irf3), NFκB p65 phosphorylated at Ser 536 (p-nf-κbp65), NF-κBp65, TBK1 44 phosphorylated at Ser 172 (p-tbk1), TBK1, NF-κBp52, NF-κBp1 phosphorylated at
45 46 47 48 49 5 Ser 866/87 (p-nf-κbp1), and β-actin was determined by immunoblotting. (C) RNAi in MEFs using the non-specific (NS) and IKKi/IKKε (upper panels) or NIK (lower panels) were stimulated with 5 µg /ml of dsdna9 for 6 h, and then total RNA was extracted from these cells, and the expression level of mrna of IL-6, CXCL1, and IKKi/IKKε or NIK were determined by real-time PCR, respectively. Real-time PCR data were normalized to the amount of GAPDH mrna.
