cGAS/STING activation in dRP lyase deficient mice. (A) Immunohistochemistry staining of stomach tissue section with DSB marker (gH2AX) in dRP lyase deficient (L22P) and WT mice; (B) Percentage of cells positive for gH2AX; (C) Immunohistochemistry staining of STING on stomach tissue of dRP lyase deficient versus proficient WT mice; (D) Percent of cells positive for STING (E) Immunohistochemistry stain of Ph-IRF3 localization in stomach tissue section of L22P versus WT mice (F) Percent of cells positive for ph-IRF3 (G) Quantification of mRNA cytosolic DNA-STING signaling mediated cytokines expression using qRT-PCR from stomach tissues derived from dRP lyase deficient and proficient WT mice. Data were analyzed using student t-test in GraphPad Prism; P*<0.05, P**<0.01, P***<0.001.
