Publication number: 20120263676Abstract: The present invention relates to compositions, methods and kits based on the ADAM-mediated cleavage of Her-2. The present invention also relates to treatments for cancer, and in particular, breast cancer, by modulating the ADAM-mediated cleavage of Her-2. Further, the invention relates to compositions, methods and kits based on the surprising synergistic effect between inhibition of Her-2 cleavage by an ADAM and certain cytostatic (e.g., Herceptin) and cytotoxic (e.g., Taxol) compounds in, among other things, inhibiting tumor cell proliferation and inducing cell death. Additionally, the invention relates to novel variants of ADAM15, designated ADAM15 variant 1 and ADAM15 variant 2, now identified and isolated.Type: ApplicationFiled: December 23, 2011Publication date: October 18, 2012Inventors: Steven M.
