Among these proteins, we also found a list of previously reported protein markers for the metastasis of various types of cancers, which showed increased abundance in the three metastatic 1424 cell lines as opposed to the EpH4-B-MEKDD 116 cell line, including tyrosine-protein kinase Lyn (LYN), homeobox protein Nkx-3.1 (NKX31), casein kinase II subunit alpha (CSK21), caveolin-1 and -2 (CAV1 and CAV2), kalirin (KALRN), glypican-1 (GPC1) and villin-1 (VILI). This evidence concerns the gene LYN and cancer.
