In cancer-related diseases, several pathways have been verified as important and accurate target pathways, such as pathways in cancer (hsa05200), hepatitis B pathway (hsa05161), prostate cancer (hsa05215), apoptosis (hsa04210), tuberculosis (hsa05152), PI3K-Akt signaling pathway (hsa04151), estrogen signaling pathway (hsa04915), insulin signaling pathway (hsa04910), ErbB signaling pathway (hsa04012), and AGE-RAGE signaling pathway (hsa04933) were enriched. The gene discussed is EGFR; the disease is prostate cancer.
