Summary:A disintegrin and metalloproteinase 28 (ADAM28) is overexpressed predominantly by carcinoma cells in more than 70% of the non-small cell lung carcinomas, showing positive correlations with carcinoma cell proliferation and metastasis. ADAM28 cleaves insulin-like growth factor binding protein-3 (IGFBP-3) in the IGF-I/IGFBP-3 complex, leading to stimulation of cell proliferation by intact IGF-I released from the complex. ADAM28 also degrades von Willebrand factor (VWF), which induces apoptosis in human carcinoma cell lines with negligible ADAM28 expression, and the VWF digestion by ADAM28-expressing carcinoma cells facilitates them to escape from VWF-induced apoptosis, resulting in promotion of metastasis. We have developed human antibodies against ADAM28 and shown that one of them significantly inhibits tumor growth and metastasis using lung adenocarcinoma cells. Our data suggest that ADAM28 may be a new molecular target for therapy of the patients with ADAM28-expressing non-small cell lung carcinoma.
