IRF3 and neoplasm: Following co‐culture of CD8+ T cells with TYST or TYST‐sh‐cGAS cells in the presence or absence of GPC3144‐152 peptide, we analyzed the levels of cGAS and γH2AX phosphorylation by immunofluorescence, and the relative levels of TANK‐binding kinase 1 (TBK1) and interferon regulatory factor 3 (IFR3) expression and phosphorylation in tumor cells by Western blot.
