Finally, 9 pathways with the smallest P values were selected: phosphatidylinositol 3 kinase/protein kinase B (PI3K-Akt) signaling pathways, prostate cancer, bladder cancer, pancreatic cancer, IL-17 signaling pathway, non-small cell lung cancer, TNF signaling pathway, and small cell lung cancer. The gene discussed is AKT1; the disease is small cell lung carcinoma.
