N-cadherin knock-down decreases invasiveness of esophageal squamous cell carcinoma in vitro

Figure 4 E-cadherin, N-cadherin and MMP-9 proteins detected by Western bloting. 1: Positive control; 2: Untreated EC9706 cells; 3: EC9706 cells with control vector; 4: EC9706 cells with N-cadherin RNAi. E-cadherin proteins were 0.247 ± 0.010, 0.252 ± 0.087, 0.249 ± 0.07 and 0.250 ± 0.006, respectively, from lane 1 to lane 4. P > 0.05. The N-cadherin proteins were 0.681 ± 0.003, 0.679 ± 0.004, 0.653 ± 0.009 and 0.342 ± 0.006, respectively, from lane 1 to lane 4. P < 0.05. The MMP-9 proteins were 0.624 ± 0.011, 0.628 ± 0.010, 0.623 ± 0.009 and 0.282 ± 0.010, respectively, from lane 1 to lane 4. P < 0.05.
