Since various NSCLC cell lines, including H1650, H1975, A549 and H226 cells we used, express vascular endothelial growth factor receptor (VEGFR) [39–41], we concluded that increased VEGF-C by overexpressing ILT4 might enhance tumor cells motility by binding its receptor. The gene discussed is LILRB2; the disease is non-small cell lung carcinoma.
