The results showed that the main pathways for WK to treat gastric cancer may be the PI3K-Akt signaling pathway, MAPK signaling pathway, Ras signaling pathway, and VEGF signaling pathway etc. According to the information drawn from the result of MCODE networks and the conclusion of KEGG analysis, we think the MAPK signaling pathway is more likely to be the main pathway for WK to deal with gastric cancer. The gene discussed is AKT1; the disease is gastric cancer.
