Figure Lengend Snippet: A ) LPS treatment induced a strong induction of MitAP. (B) LPS stimulation induces translocation of STING RRAA to the Golgi, as assessed by anti-GFP staining and GM130 labeling, by 60 min, followed by exit from the Golgi by 240 min. Scale bar, 5 µm. (C) Neither LPS nor DMXAA treatment induces translocation of STING RRDD to the Golgi up to 120 min. Scale bar, 5 µm. D) Pre-treatment of WT RAW cells with DMXAA, which induces STING translocation to the Golgi, attenuates LPS-induced MitAP. E ) Pre-treatment of WT RAW cells with the TBK1 inhibitor (BX795) inhibits LPS-induced UPR.
