Specifically, a comparison of G1 (C57BL/6J‐STING‐KO, Mc38‐hHER2, and Mc38‐hHER2, vehicle) and G2 (C57BL/6J‐STING‐KO, Mc38‐hHER2, B002T‐LP004) tumors revealed that the STING of tumor tissues has only a weak tumor‐suppressing effect in the presence of ISAC (Figure 4B). This evidence concerns the gene STING1 and neoplasm.
