The gene signature that negatively regulated cancer immune cycle was downloaded from the website “Tracking Tumor Immunophenotype.” The results showed that most of these genes, such as arginase 1 (ARG1), CD 160 molecule (CD160), CD 244 molecule (CD244), C-X-C motif chemokine ligand 12 (CXCL12), DNA methyltransferase 1 (DNMT1), and hepatitis A virus cellular receptor 1 (HAVCR1), were upregulated in the high hypoxia risk group (Figure 7). The gene discussed is CD160; the disease is cancer.
