TP53 and small cell lung carcinoma: KEGG pathway analysis suggests that these genes are enriched with Cell cycle, ECM–receptor interaction, p53 signaling pathway, DNA replication, Focal adhesion, Small cell lung cancer and PI3K-Akt signaling pathway related to tumor functions (Table 2) while GO enrichment analysis shows that they are enriched with platelet-derived growth factor binding, extracellular matrix structural constituent, structural molecule activity, phospholipase A2 inhibitor activity and protein binding pathway (Table 3).
