These patent applications describe and claim inventions related to the protein sFRP-1 and methods of regulating signal transduction pathways using sFRP-1. sFRP-1 is a member of a family of secreted proteins (secreted Frizzled Related Proteins) that were originally identified as being able to bind to Wnt proteins. When bound to Wnts, sFRP-1 alters the ability of Wnt protein to bind its receptor (Frizzled), typically acting as an antagonist of Wnt signaling.
More particularly, the patent applications and inventions claimed therein relate to methods for influencing bone remodeling using sFRP-1. In particular, the patent application and claimed inventions relate to methods of inhibiting osteoclastogenesis with the sFRP-1 protein. The ability to inhibit osteoclast formation may be of value in developing treatments for diseases such as post-menopausal osteoporosis, Paget's disease, lytic bone metastases, multiple myeloma, hyperparathyroidism, rheumatoid arthritis, periodontitis and hypercalcemia of malignancy.
In addition to describing the method of inhibiting osteoclast formation, the patent applications disclose various peptides containing a conserved motif that allows the peptide containing the motif to bind to sFRP-1.
Researchers at the NCI seek licensing and/or co-development research collaborations for the inhibition of osteoclast formation using peptides capable of binding sFRP-1.
