KLK7 and melanoma: Although the pathways responsible for KLK7‐mediated stimulation of melanoma cell migration and invasion are beyond the scope of this report, it is worth to note that using protease array techniques, an upregulation of members of the cathepsin family, certain matrix metalloproteinases, and proteases inhibitors was observed in cell culture supernatants of melanoma cells that overexpress KLK7 (data not shown).
