Antigens downregulated in metastasis.

Antibody array results showing surface antigens that were at least two-fold decreased in cell positivity in SW620 (metastatic) as compared to SW480 (primary). Abbreviations: epidermal growth factor receptor, EGFR; neural cell adhesion molecule, NCAM; C-X-C chemokine receptor 4, CXCR4; selectin P ligand, SELPLG; urokinase receptor, UPAR; FAS receptor, FasR; dendritic cell-specific intercellular adhesion molecule-3-grabbing non-integrin, DC-SIGN; low density lipoprotein receptor related protein 1, LRP1; glycoprotein 130, gp130; natural cytotoxicity triggering receptor 3, NCR3; semaphorin-4D, SEMA4D; C-C chemokine receptor 3, CCR3; low affinity nerve growth factor receptor; LNGFR; interleukin 8 receptor alpha, IL8RA; P-glycoprotein, P-gp; intercellular adhesion molecule 1, ICAM1. *, Antigen was not two-fold decreased by comparison of mean fluorescence intensities (Table S4).
