DDX27 and gastric cancer: Subsequently, we detected the DDX27 mRNA and protein levels in different GC cell lines and noticed that compared to the normal gastric epithelial cell line (GES-1), DDX27 was significantly upregulated in the GC cells (AGS, BGC-823, MKN-45, MKN-28, SNU-1, and HGC-27) (Figure 1B).
