PERP, BAK1, CDK2, VDAC1, MDM2, HDAC1, FOXO3, AKT3, and IGF expression were significantly negatively related to tumor purity and positively correlated with T cells (CD8 and CD4), macrophages, neutrophils, and DCs in CESC, but not significantly correlated with B cells (Figure 5A–I). The gene discussed is CD8A; the disease is neoplasm.
