Notably, genes mediated by IFN-γ, a key cytokine in the tumor microenvironment were also significantly upregulated in high inflammation (STAT1, CCR5, CXCL9, CXCL10, CXCL11, CCL2, CCL4, CCL5, CCL13, CCL17, CCL18, CCL19, CCL21, CCL22, IDO1, PRF1, IRF4, IRF8, GZMA, HLA-DRA, HLA-DMA, Fig. 3B). The gene discussed is CCL2; the disease is neoplasm.
