Total expression of β-catenin or non-phospho β-catenin (active β-catenin), focal adhesion kinase (FAK) or the active form phospho FAK (Y397) were measured in different melanoma cell lines from either uveal melanoma cells: MUM 2B (VE-Cadherin positive, NRP-1 positive, VEGFR2 negative, Fig. S1A) and MUM 2C (VE-Cadherin negative, NRP-1 negative, VEGFR2 negative, Fig. S1A), or cutaneous melanoma cells: C8161 (VE-Cadherin positive, NRP-1 positive) and C81-61 (VE-Cadherin negative, NRP-1 negative). This evidence concerns the gene KDR and uveal melanoma.
