Compared with G3 (wt C57BL/6J, Mc38‐hHER2‐STING‐KO, vehicle) and G4 (wt C57BL/6J, Mc38‐hHER2‐STING‐KO, B002T‐LP004) tumors, when the ISAC drug is administered to mice in the normal state, the number of tumor cells is significantly suppressed (Figure 4C), and when both STING in mice and STING of the tumor cells are removed, the proliferation rate of the tumor cells is significantly increased (Figure 4D). This evidence concerns the gene STING1 and neoplasm.
