Patent number: 6787336Abstract: The present invention relates to DNA molecules which encode antagonists of vertebrate growth hormones obtained by mutation of at least the amino acid corresponding to Glu-119 in bovine growth hormone. The DNA molecules may be used to express the antagonists, either in cell culture, or in the cells of the patient of interest. The antagonist so expressed may be used to inhibit GH activity in a subject.Type: GrantFiled: June 7, 1995Date of Patent: September 7, 2004Assignee: Ohio University/Edison Biotechnology InstituteInventors: John J.

Patent number: 6583115Abstract: The present invention relates to antagonists of vertebrate growth hormones obtained by mutation of the third alpha helix of such proteins (especially bovine or human GHs). These mutants-have growth-inhibitory or other GH-antagonizing effects. These novel hormones may be administered exogenously to animals, or transgenic animals may be made that express the antagonist. Animals have been made which exhibited a reduced growth phenotype. The invention also describes methods of treating acromegaly, gigantism, cancer, diabetes, vascular eye diseases (diabetic retinopathy, retinopathy of prematurity, age-related macular degeneration, retinopathy of sickle-cell anemia, etc.) as well as nephropathy and other diseases, by administering an effective amount of a growth hormone antagonist. The invention also provides pharmaceutical formulations comprising one or more growth hormone antagonists.Type: GrantFiled: June 7, 1995Date of Patent: June 24, 2003Assignee: Ohio University/Edison Biotechnology InstituteInventors: John J.
