Figure 3: (a) Flow cytometry of the gastric cancer cell cycle. A higher proportion of SCG7901 cells remained in the G0/G1 phase in pcDNA3/15-PGDH-1 and pcDNA3/15-PGDH-2 groups than in the other groups. (b) p16, p21 and p53 mRNA in four SGC7901 cells groups (pcDNA3/15-PGDH-1 and pcDNA3/15-PGDH-2 groupsvs. other groups, p<0.05).
