A Hypoxia Gene-Based Signature to Predict the Survival and Affect the Tumor Immune Microenvironment of Osteosarcoma in Children

Figure 7

High-risk score suggests a microenvironment with immunosuppression: (a) a heat map of the gene profiles participating in cancer/immune system cycle in two groups in TARGET and GEO databases; (b) association between PD1 expression and risk score; (c) correlation between PD1 and risk score; (d) PD1 level in two groups; (e) tumor immune cytokine expression in two groups.
