Gene set enrichment analysis (GSEA) revealed negative correlations between YTHDF1 overexpression and cancer immunity–related gene sets, including “Antigen processing and presentation” and “Allograft rejection” from the KEGG gene set, as well as “Immunoglobulin mediated immune response” from the gene ontology (GO) gene set (Figure 3C; Figure S3B, Supporting Information). Here, YTHDF1 is linked to cancer.
