Extended Data Fig. 2: STING vesicles retained in the cytosol by Baf A1 or CQ restricts aerobic glycolysis.
From: STING is a cell-intrinsic metabolic checkpoint restricting aerobic glycolysis by targeting HK2

a, L929 cells were transfected with control siRNA or Tsg101 siRNA, and the expression of Tsg101 was quantified at 72 h post-transfection. b, L929 cells from (a) were stimulated with HT-DNA (1 μg/ml) for 8 h. The expression of Cxcl10 and Isg56 was quantified by qPCR. c, L929 cells from (a) were stimulated with HT-DNA (1 μg/ml) for 24 h, followed by lactate measurement. d, L929 cells were transfected with Control siRNA or Atp6v1b2 siRNA, and the expression of Atp6v1b2 was quantified at 72 h post-transfection. e, Sting1−/− MLF cells stably expressing mRuby3-mSTING and Lamp1-EGFP were treated with control siRNA, Atp6v1b2 siRNA or Tsg101 siRNA for 60 h, and then stimulated with DMXAA (25 μg/ml) for 12 h. Cells were fixed and imaged by STED super-resolution microscopy. Scale bars, 5 μm. The boxed areas in the top panels were magnified in the bottom, and the fluorescence intensity profiles along the white dotted lines were shown. f, Sting1−/− MLF cells stably expressing mRuby3-mSTING and Lamp1-EGFP were stimulated with DMXAA (25 μg/ml), and treated with brefeldin A (10 μg/ml), chloroquine (20 μM), or bafilomycin A1 (400 nM) for 12 h. Cells were fixed and imaged by STED super-resolution microscopy. Scale bars, 5 μm. The boxed areas in the top panels were magnified in the bottom, and the fluorescence intensity profiles along the white dotted lines were shown. g, immunoblotting analysis of THP-1 cells infected with HSV-1 (MOI = 1). h and i, Sting1−/−L929 cells stably expressing FLAG-STING were transfected with HT-DNA (1 μg/ml) (h) or infected with HSV-1 (MOI = 1) (i), followed by immunoblotting. Data are presented as means ± s.d. of n = 3 independent biological replicates for a-d. P-value was calculated by two-tailed Student’s t-test. Data are representative of three independent experiments. Uncropped gel images and numerical data are available in source data.
