A panel of NSCLC cell lines (H460, H647, A549 and SKMES1) was screened for the expression of the VEGF ligand (Figure 1A) and its receptors, VEGFR-1 (Flt-1), VEGFR-2 (KDR), NP1 and NP2 at the mRNA (Figure 1B) and protein levels (Figure 1C). This evidence concerns the gene NRP2 and non-small cell lung carcinoma.
