Considering the interaction between tumor antigens and antigen presenting cells (APCs), these potential antigens were further screened for APC association through the TIMER database where it was found that the AGPS, NRAS, MTDH, PANX1, NOX4, and PPARD genes showed a positive correlation with different APCs (Fig. 3A–F), and the prognosis was poorer for the genes with high expression (Figs. 4A–F and 5A–F). This evidence concerns the gene PPARD and neoplasm.
