According to PPI network results, key targets of WK in the treatment of gastric cancer are likely to be VEGFA, AKT1, EGFR, STAT3, ERS1, HSP90AA1, etc. Based on the enrichment analysis of GO and KEGG pathways, we believe that the PI3K-Akt signaling pathway, MAPK signaling pathway, Ras signaling pathway, and VEGF signaling pathway are the main pathways participating in the gastric cancer treatment of WK. Here, EGFR is linked to gastric cancer.
