There were nine enriched KEGG pathways, including MAPK signaling pathway, salmonella infection, signaling pathways regulating pluripotency of stem cells, Yersinia infection, apoptosis, sphingolipid signaling pathway, central carbon metabolism in cancer, Fc epsilon RI signaling pathway and VEGF signaling pathway, were identified (Fig. 8A). This evidence concerns the gene VEGFA and cancer.
