Furthermore, we researched genes involved in the PD-L1 pathway which include EGFR, HRAS, RAF1, ALK, PIK3CA, PTEN, AKT3, EGF, MAP2K1, MAPK1, MTOR, RPS6KB1, CHUK, NFKBIA, NFKB1, IFNG, IFNGR1, STAT1, TLR9, TIRAP, MYD88, TRAF6, TICAM1, TICAM2, FOS, HIF1A, and NFATC1 in gastric cancer. Here, TICAM1 is linked to gastric cancer.
