| Outline of Final Research Achievements |
ADAM28, a member of the ADAM (a disintegrin and metalloproteinase) gene family, plays an important role in cancer cell proliferation and metastasis. In the present study, we screened Human Combinatorial Antibody Library by phage display panning and obtained antibodies (211-14 and 211-12) against ADAM28. Tumor growth and metastasis of the lung tumors after intravenous injection of PC-9 ffLuc-cp156 lung carcinoma cells were significantly inhibited by the antibody treatment, improving survival rate of the mice. These data indicate that our antibodies 211-14 and 211-12 neutralize ADAM28 activity and antibody 211-14 inhibits cancer cell proliferation and metastasis in vivo. The antibodies could be used as an ADAM28 inhibitor for clinical application to treat the patients with lung or breast carcinoma in the future.
