According to IPA, both mTOR and IGF‐1 signalling, which are tightly related to tumour invasion in GC,65 were positively regulated in E0 cells, and diseases and biofunctions analysis showed that E0 cells may increase the invasion and migration of tumour cells (Figure 4C and D), indicating that E0 cells promote GC invasion. The gene discussed is IGF1; the disease is gastric cancer.
