Figure 5. Different immune and cancer-related characteristics in gene cluster D and E. (A) The 23 kinds of immune cells in the two gene clusters. (B) Significant differences in expression of immune checkpoint between the two gene clusters. (C) The enrichment levels of cancer-related signatures in the two gene clusters. (D) Expression levels of HLA genes between gene cluster D and E. *p < 0.05; **p < 0.01; ***p < 0.001.
