KEGG enrichment analysis results showed that spliceosome, Vegf signaling pathway, jak stat signaling pathway, non small cell lung cancer and notch signaling pathway were highly expressed in high-risk group, and amino sugar and nucleotide sugar metabolism, glycolysis gluconeogenesis, oxidative phosphorylation, pentose phosphate pathway and ribosome were highly expressed in low-risk group (Fig. 5k). The gene discussed is VEGFA; the disease is non-small cell lung carcinoma.
