Fig. 6From: Does VEGF facilitate local tumor growth and spread into the abdominal cavity by suppressing endothelial cell adhesion, thus increasing vascular peritoneal permeability followed by ascites production in ovarian cancer?Correlation between adhesion protein expression (VE-cadherin and claudin 5) and VEGF in the peritoneum. Correlation between claudin 5 and VE-cadherin in the peritoneum of ovarian cancer patients. By plotting the values of real-time PCR-analysis against each other a significant linear correlation between claudin 5 and VE-cadherin was detected (rS = 0.839, p < 0.001) (a). Plotting the VEGF expression against VE-cadherin or claudin 5 expression showed significant negative correlations (VE-c: rS = −0,384, p = 0.012) (cl 5: rS = −0.355, p = 0.021); the scatter plots indicate that there might be a hyperbolic function rather than a linear relationship in both cases (b and c)Back to article page
