RIGI and cancer: We next investigated the expression of the interferon‐stimulated genes (ISGs) and double‐stranded RNA‐editing enzymes ADAR1 and ADAR2, the former of which is critically required for cancer cell survival in ISG signature‐positive tumors.31, 32 RIG‐I levels correlated significantly with ADAR1 expression (p < 0.001, Fig. 4e) but were less strongly associated with ADAR2 expression (p = 0.043, Fig. 4f).
