HLA-C and neoplasm: GO enrichment analysis showed that the 1735 differentially expressed genes were mainly enriched in immune functions such as C–C chemokine binding, chemokine receptor activity, G protein-coupled chemoattractant receptor activity, MHC protein complex binding, cytokine receptor activity in the MC, and tumour immunities, including positive regulation of the Wnt signalling pathway, T cell receptor signalling pathway, T cell activation, negative regulation of cell cycle process and antigen processing and presentation in BP (Fig. 4G and Table S10).
