Figure 3. Comparison of VEGFR1 Gene Expression in AGS Cells Using Semi-Quantitative RT-PCR in Presence and Absence of Anti-VEGFR1 siRNA.

1, DNA marker; 2, pEGFP-VEGFR1 transfected cells without siRNA treatment; 3, pEGFP-VEGFR1 transfected cells after treatment with siRNA. As shown, VEGFR1mRNA level decreased in presence of specific anti-VEGFR1 siRNA. β-actin was used a reference gene for comparison.
