Moreover, analysis using TCGA pan-cancer data provided the same results: high expression of FCGBP correlated well with macrophage infiltration and polarization in ACC (Supplementary Figure 2A−2C), BRCA (Supplementary Figure 2D−2F), MESO (Supplementary Figure 2G−2I), PAPG (Supplementary Figure 2J−2L), and SARC (Supplementary Figure 2M−2O). Here, PAPOLG is linked to cancer.
