Therefore, via pan-carcinoma analysis of tumor immune microenvironment, it was discovered that ANXA2P2 expression characteristics were significantly correlated with immune microenvironment scores, nucleotide excision repair, mismatch repair, immune checkpoint, EMT, DNA replication, DNA damage response, CD8 T effector, base excision repair, and antigen processing machinery (Figure 4A). The gene discussed is CD8A; the disease is neoplasm.
