Effects of angiopoietin-1 on attachment and metastasis of human gastric cancer cell line BGC-823

Figure 6 Expression of integrin β1 (A) and CD44V6 (B) protein (× 200). A: Expression of integrin β1 in the Ad-Ang-1-transfected group was 0.183 ± 0.014, which was significantly higher than that in the control group (0.114 ± 0.023, P < 0.05) and Ad-GFP-transfected group (0.149 ± 0.013, P < 0.05); B: Compared with the other groups, expression of CD44V6 was also up-regulated. The staining intensity for this protein in the Ad-Ang-1-transfected group (0.147 ± 0.011) was higher than that in the control group (0.089 ± 0.007, P < 0.05) and Ad-GFP-transfected group (0.065 ± 0.021, P < 0.05). Diagrams are representive of at least three independent experiments.
