The results showed that, when compared with gastric normal epithelial mucosae cell line GES-1 and adjacent non-cancerous tissues, the expression of SERPINE1 and EFNA3 were significantly higher in gastric cancer cell lines (Figures 10E, F, except for SERPINE1 in HGC-27, P > 0.05) and gastric cancer tissues (P < 0.05) (Figures 10G, H). The gene discussed is SERPINE1; the disease is gastric cancer.
