More importantly, in BLCA, LIHC, PRAD, and FASN, negatively related genes were significantly enriched in Th1 and Th2 cell differentiation pathways, and pathways related to tumor immune regulation, such as cytokine–cytokine-receptor interaction, antigen processing and presentation, and chemokine signaling pathways (Figure 10C–E). This evidence concerns the gene FASN and neoplasm.
