摘要: To explore the potential therapeutic targets of early‑stage non-small cell lung cancer (NSCLC), gene microarray analysis was conducted. The data NSCLC in stage IA, IB, IIA, and IIB (GSE50081), were downloaded from Gene Expression Omnibus (GEO) database. differentially expressed genes (DEGs) IB vs. IIA screened out via R. ToppGene Suite used to get enriched Ontology (GO) terms Kyoto Encyclopedia Genes Genomes (KEGG) pathways DEGs. GeneCoDis3 database Cytoscape software construct transcriptional regulatory network. In total, 25, 17 14 DEGs identified NSCLC, respectively. Some GO (e.g., extracellular space, alveolar lamellar body, bioactivation cytochrome P450 pathway) found significantly S100P, ALOX15B, CCL11, NLRP2, SERPINA3, FoxO4 hsa-miR-491 may play important roles development early-stage NSCLC. Thus, by bioinformatics key biological processes involving could be established, providing more references for targets.
