Finally, we identified 55, 47, 50, 39, 48, 58, and 50 genes regulated by p53 for TCGA lung cancer (LUNG), breast cancer (BRCA), colon cancer (COAD), head and neck cancer (HNSC), stomach cancer (STAD), endometrioid cancer (UCEC), and liver cancer (LIHC) cohorts, respectively. This evidence concerns the gene TP53 and gastric adenocarcinoma.
