Analysis of the TCGA data showed TP53 mutations in 22% of LUAD patients. Clinicopathological analyses demonstrated that TP53 mutation was correlated with the disease progression but not prognosis. We identified 1935 differentially expressed genes (DEGs). Functional enrichment analysis showed that the DEGs were mainly concentrated in metabolism, cell differentiation, and cancer-related pathways. The top hub genes were identified and disease analysis revealed the most critical genes related to disease progression and prognosis. The expression levels of several of these genes were then tested in tumor tissues. Our results showed that TP53 mutation plays a critical role in cellular process and the clinicopathological findings in LUAD. We also identified potential key genes, which could provide novel evidence for individualized treatment. READ ARTICLE
