RT-qPCR results showed that the mRNA expression level of GEMIN5 and PFDN2 were higher in cancer cells of HGC27, BGC823, AGS, MGC803, SGC7901, and MKN45 than in human normal mucosal epithelium cells GES-1 (Figures 6C, D).Also, the mRNA expression level of GEMIN5 and PFDN2 were higher in GC tissues than in normal gastric tissues (Figures 6E, F). Here, PFDN2 is linked to cancer.
