Furthermore, we discerned numerous cancer-related biological functions and signaling pathways enriched in patients of subtype B, such as p53, Wnt/β-catenin signaling pathways, epithelial–mesenchymal transition (EMT), angiogenesis, and cell cycle regulation, potentially resulting in a dismal prognosis for patients of subtype B. Analogous outcomes were attained via GO/KEGG analyses. This evidence concerns the gene TP53 and cancer.
