Figure 1From: Chronic inhibition of tumor cell-derived VEGF enhances the malignant phenotype of colorectal cancer cells Effect of inhibition of cancer cell-derived secreted VEGF on VEGF family profile. Cells were treated without (none) or with an unimmunized IgG or an anti-VEGF mAb for 2 or 60 days. Expression levels of Vegf (A), Plgf (B), Vegfr1 (C), and Vegfr2 (D) were measured by quantitative RT-PCR (n=4, means ± S.D.). *P < 0.01.Back to article page
