STING-dependent gene regulation in E17 Sting−/− DNase II−/−embryos. (A) STING and DNase II expression by qPCR and Western blot from E17 fetal liver wild-type (eWT), Sting−/− DNase II+/+(eStingKO), Sting+/− DNase II−/− (eDNaseIIKO), and Sting−/− DNase II−/− (eDoubleKO) embryos. (B) Macroscopic view of E17 Sting+/− DNase II+/−(Left), eDNaseIIKO (Center), and eDoubleKO (Right) embryos. (C) H&E and TUNEL stains from mice livers same as A. Feulgen stain of BMDM after incubation with thymocytes (+) Dex. (Magnification: 200×.)
