The invention relates to the identification and generation of antibodies that bind to TMEFF2 proteins which are involved in cancer. Further, the invention provides for the use of these antibodies in the treatment of cancer.

Antibodies against cancer antigen TMEFF2 and uses thereof

Described herein are methods and compositions that can be used for diagnosis and treatment of cancer.

GPR64 antibody compositions are provided. These antibodies may be used for diagnosis or treatment of cancer, especially ovarian cancer, Ewing's sarcoma, uterine cancer, and other GPR64 expressing tumor types.

Antibodies against GPR64 and uses thereof

The present invention provides methods for direct killing of cancer cells using anti-&#x3b1;5&#x3b2;1 antibodies. Generally, the method comprises contacting a cancer cell that expresses &#x3b1;5&#x3b2;1 on its surface with an anti-&#x3b1;5&#x3b2;1 antibody, and thereby inducing the death of the cancer cell. The methods of the invention may be employed at an early stage of cancer development in a patient to prevent tumor establishment. In addition, the methods may be used to treat previously formed tumors especially in cancer that have not proven susceptible to anti-angiogenesis therapy. The methods may be employed as a combination therapy of anti-&#x3b1;5&#x3b2;1 antibodies together with cancer chemotherapeutic agents or other molecular-based cancer therapeutic agents.

Use of anti-&#x3b1;5&#x3b2;1 antibodies to inhibit cancer cell proliferation

Particular anti-LFL2 antibody compositions are provided herein. These antibodies may be used for diagnosis, prognosis, therapeutic monitoring and treatment of cancer, especially breast cancer, head/neck cancer, lung cancer, ovarian cancer, stomach cancer and pancreatic cancer. Furthermore, anti-LFL2 antibodies are provided herein which target the LFL2 stump remaining after proteolytic cleavage of the extracellular domain of LFL2. Additionally, anti-LFL2 antibodies are provided herein which target the stroma surrounding cancer tumors, wherein said stroma-targeting anti-LFL2 antibodies disrupt the integrity of the stroma surrounding the cancer tumor, and also make the stroma more permeable to chemotherapeutic agents and other molecular drug agents that target tumor cells.
