Figure 2From: Biomarkers for antitumor activity of bevacizumab in gastric cancer models Expression of human VEGF proteins in tumor tissues of gastric and colorectal cancer xenograft models. (A) The level of human VEGF (black bar) and VEGF165b (open bar) protein in bevacizumab-sensitive and bevacizumab-insensitive tumor tissues was quantified by ELISA (n = 4/group). (B) The quantity of VEGF was compared between the two groups. The averages were shown as bars and numeric values. *: P < 0.05 vs. sensitive group by Wilcoxon test.Back to article page
