Roles for dual endothelin-1/angiotensin II receptor (Dear) in hypertension and angiogenesis
The present application is directed to the identification of mutations and/or polymorphisms in the Dual Endothelin-1/Angiotensin II Receptor (Dear) that indicate susceptibility to, or show current affliction with, hypertension. Additionally, the present invention discloses methods for the modulation of angiogenesis via the regulation of Dear.
1. A method for inhibiting angiogenesis in an individual comprising administering to said patient an antibody or antibody fragment that can block binding to the Dual Endothelin-1/Angiotensin II Receptor (Dear) ET-1 domain.
2. The method of claim 1 , wherein the antibody or antibody fragment is a humanized antibody or antibody fragment.
3. The method of claim 1 , wherein the angiogenesis is associated with a disease or disorder selected from the group consisting of, immune and non-immune inflammation, chronic articular rheumatism, psoriasis, diabetic retinopathy, neovascular glaucoma, restenosis, macular degeneration, capillary proliferation in atherosclerotic plaques, osteoporosis, cancer, solid tumors, solid tumor metastases, angiofibromas, retrolental fibroplasia, hemangiomas, and Kaposi sarcoma.
4. The method of claim 1 , wherein the antibody or antibody fragments blocks binding to the ET-1 domain of SEQ ID NO: 2.
5. The method of claim 1 , wherein the ET-1 domain comprises amino acids 60-67 of SEQ ID NO: 2.
