The FDR corrected P < 0.05 was used as an enrichment screening criterion, and the top 32 enriched functional clusters of potential therapeutic targets were obtained (Figure 3), including “non-small cell lung cancer” (17 genes), “small cell lung cancer” (19 genes), “TNF signaling pathway” (28 genes), “HIF-1 signaling pathway” (26 genes), “PI3K-Akt signaling pathway” (48 genes), and “T cell receptor signaling pathway” (22 genes). The gene discussed is AKT1; the disease is small cell lung carcinoma.
