To inspect the phenotypes induced by gankyrin in gastric cancer cells, we firstly identified the basal levels of human normal gastric epithelial cell (GSE-1) and several gastric cancer cell lines using Western blot analysis and the results revealed that high gankyrin expression was observed in all cancer cell lines, but it was undetectable in GES-1 (Figure 2(a)). This evidence concerns the gene PSMD10 and cancer.
