Significance of vascular endothelial growth factor expression and its correlation with inducible nitric oxide synthase in gastric cancer

Figure 1 RT-PCR products of VEGF₁₆₅mRNA by 20 g/L agar-ose gel electrophoresis. M: Marker; P: Recombined plasmid of VEGF₁₆₅; T: Gastric cancer mucosae; N; Non-gastric cancer mucosae; ‘: β-actin. The product of VEGF₁₆₅ mRNA was 655 bp, and the product of β-actin was 370 bp.

A: Negative staining of VEGF in normal paired gastric mucosae (× 100); B: Positive staining of VEGF in gastric cancer (× 100); C: Negative staining of iNOS in normal paired gastric mucosae (× 100); D: Positive staining of iNOS in gastric cancer (× 100).
