Expression of VEGF-D-binding receptors by 468LN cells:

<p>(<b>A</b>) Expression of VEGF-R2 and R3 mRNA examined with semi quantitative RT-PCR, and (<b>B</b>) α9 integrin mRNA measured with qRT-PCR. (<b>C</b>) Confirmation of VEGF-R2, VEGF-R3, and α9 integrin expression at protein levels by western blot. MDA-MB-231 and MCF7-COX-2 cells were used as positive controls primarily for VEGF-R2 and VEGF-R3 expression. Differentially high α9 integrin expression by 468 LN cells was evident. Bars represent mean (n = 4) ± SE, *,P<0.05.
