To explore the clinical relevance of the key genes in the tumor immune subsets of CESC cases, we generated a Kaplan–Meier curve to compare the expressions of PERP (Figure 6A), BAK1 (Figure 6B), CDK2 (Figure 6C), VDAC1 (Figure 6D), MDM2 (Figure 6E), HDAC1 (Figure 6F), FOXO3 (Figure 6G), AKT3 (Figure 6H), and IGF1 (Figure 6I) at different expression levels of immune infiltration. The gene discussed is CDK2; the disease is cervical squamous cell carcinoma.
