Compounds, compositions and uses thereof for improvement of bone disorders
The present technology generally relates to peptides of IGFBP-2 that may be used to improve bone disorders. The present technology also generally relates to uses of such peptides in methods for preventing or treating bone disorders and to compositions for such uses.
1. An isolated peptide consisting of a heparin binding domain (HBD) fragment as set forth in SEQ ID NO: 73.
2. A composition comprising the isolated peptide of claim 1 together with a suitable pharmaceutical excipient.
3. A method for treatment of a bone disorder in a subject in need thereof, the method comprising administering the isolated peptide of claim 1 to the subject in an amount effective to treat the bone disorder in the subject.
4. The method of claim 3 , wherein the bone disorder is selected from: osteoporosis, osteopenia, osteogenesis imperfecta, osteonecrosis, low bone mass, Paget's disease of bone, aseptic prosthetic loosening, metastatic bone disease, rheumatoid arthritis, lupus arthritis, periodontal disease, alveolar bone loss, post-osteotomy, childhood idiopathic bone loss, curvature of the spine, loss of height, and prosthetic surgery.
5. The method of claim 4 , wherein the bone disorder is selected from: a broken bone, a bone defect, a bone transplant, a bone graft, a bone cancer, a joint replacement, a joint repair, a fusion, a facet repair, a bone degeneration, a dental implant, a dental repair, and any combination thereof.
6. The method of claim 3 , wherein the effective amount is from about 1 μg/kg to about 50 mg/kg.
7. The method of claim 3 , wherein said administering is continued for a period of at least about 10 weeks or about 24 weeks.
