Figure 6. Association between KIF14 expression and immune infiltration in LUAD. (A–C) The association of KIF14 expression with TMB (A), MSI (B) and immune checkpoint-related genes (C) in pan-cancer. (D–F) The associations of KIF14 expression with PD-1 (D), CD274 (E) and CTLA4 (F) expression in LUAD, which were determined using the TIMER database. *P-value < 0.05, **P-value < 0.01, ***P-value < 0.001.
