Next, we performed pathway enrichment analysis of genes with altered expressions and found that multiple tumors and tumor-related signaling pathways were enriched, such as in Gastric cancer, Breast cancer, Bladder cancer, and signaling pathways, including the p53 signaling pathway, the MAPK signaling pathway, the Wnt signaling pathway, the Hippo signaling pathway, and the JAK-STAT signaling pathway. The gene discussed is TP53; the disease is gastric cancer.
