Consistent with in vitro results, we observed more metastatic cancer cells in liver tissues from mice injected with MKN28-EGFL7, BGC823, or BGC-NC cells compared to mice injected with BGC2-13, MKN28, or MKN28-NC cells (Figure 5B) indicating that overexpression (whether via transfection or endogenous) promotes liver metastasis of GC cells. The gene discussed is EGFL7; the disease is gastric cancer.
