The expression of ADAM10 (a disintegrin and metalloproteinase 10) was characterized in melanoma cells in vitro and in vivo. ADAM10 was significantly elevated (P = 0.04) in metastasizing melanomas compared with those of primary origin. Overexpression of ADAM10 induced the migration of melanoma cells and correlated with increased cell proliferation. Knockdown of cellular L1-CAM (L1-adhesion molecule) decreased the migration of melanoma cells and abrogated their chemoresistance due to cisplatin. ADAM10 and L1-CAM have important functions in melanoma progression and thus present putative targets for therapeutic intervention (Lee, S.B. et al. J Invest Dermatol 2010, 130: 763).
