CD4 and cancer: FASN expression was significantly negatively correlated with CD8+ T cells (BLCA, BRCA, CESC, HNSC, LGG, LUAD, LUSC, OV, SKCM, STAD), CD4+ T cells (BLCA, BRCA, ESCA, HNSC, PRAD, SARC, SKCM, STAD, TGCT, THCA), and DC cells (BLCA, HNSC, LGG, LIHC, LUAD, LUSC) infiltration in multiple cancer cell types using TIMER analysis, which is consistent with the ImmuCellAI results (Figure 4F).
