Ddx41 regulates inflammatory signaling via the cGAS-STING pathway (A) Schematic of the Ser172-phosphorylated TBK1 (pTBK1) immunofluorescence experiments. (B) Confocal images showing immunofluorescence of pTBK1 and nuclei (DAPI) in cells isolated from 40 hpf siblings, ddx41 mutants (control), ddx41 mutants injected with cGAS translation-blocking (ATG) MO, RNH1-negative ddx41 mutants and RNH1-positive ddx41 mutants. Scale bar, 5 ?m. (C) Quantification of pTBK1 levels from (B). (D) Flow cytometry plots of NF?B:gfp+ cells from sibling controls (left) and ddx41 mutants (right) at 40 hpf. (E) Graph depicting the absolute number of NF?B:gfp-high cells per embryo shown in (D). (F) Schematic of the cGAS-STING pathway knockdown experiments with NF?B:gfp quantification. (G) Flow cytometry plots of NF?B:gfp+ cells from ddx41 mutants injected with control morpholino (left), splice-blocking sting morpholino (middle), or cgas ATG morpholino (right) at 40 hpf. (H) Graph depicting the absolute number of NF?B:gfp-high cells per embryo shown in (G). Graphs display means ± stds with p values calculated with unpaired Student?s t test (E) or a one-way ANOVA with Tukey?s multiple testing correction (C and H), ?p < 0.05, ???p < 0.001, ????p < 0.0001. N = 3?5 replicates per experiment.
