We used the same method to test the levels of IFN‐γ stimulated by SNVs‐induced MFC neoantigens (MFCs),[21] and it could be seen that the concentration of IFN‐γ increased no more than fivefold compared with NS (Figure S1, Supporting Information), which indicated that FSPs were better targets for personalized neoantigen vaccines on gastric cancer. This evidence concerns the gene IFNG and gastric cancer.
