The top 15 KEGG pathways (P-value < 0.05) that the network was involved are shown in Figure 3B, indicating that the ceRNA network for LUAD was closely related to some cancer-associated pathways, such as microRNAs in cancer, transcriptional misregulation in cancer, cellular senescence, cell cycle, p53 signaling pathway, small cell lung cancer, and so on. The gene discussed is TP53; the disease is cancer.
