For biological process enrichment, the YTHDC2-related genes in LUAD and LUSC were also enriched in several cancer-related processes, including 'NF-κB signaling', 'mRNA splicing', 'cell cycle', 'cell division', 'TNF-mediated signaling' and 'Wnt signaling pathway' (Figure S6C-D). The gene discussed is TNF; the disease is cancer.
