Abstract
Compositions and methods of treatment for abnormal bone density are disclosed based upon the finding that sclerostin must be bound to glypican in order to inhibit bone deposition. Methods for identifying agents that inhibit the glypican-sclerostin interaction are disclosed for treatment of bone deposition disorders. Diagnostic methods are also disclosed.
Claims3
An in vitro method for identifying an inhibitor of the glypican-sclerostin interaction comprising the steps of:
- a) contacting sclerostin with glypican in the presence and absence of the candidate inhibitor under conditions permitting the binding of the glypican to sclerostin;
- and
- b1) measuring binding of the glypican to sclerostin, wherein a decrease in binding in the presence of the candidate inhibitor, relative to binding in the absence of the candidate inhibitor, identifies the candidate inhibitor as an inhibitor of the glypican-sclerostin interaction, or
- b2) measuring the signaling response induced by the glypican-sclerostin interaction in the presence of the candidate inhibitor, and comparing it with the signaling response induced by the glypican-sclerostin interaction in the absence of the candidate inhibitor, wherein a change in the signaling response identifies the candidate inhibitor as an inhibitor of the glypican-sclerostin interaction;
- wherein the glypican is selected from the group consisting of glypican-1, glypican-2, glypican-3, glypican-4, glypican-5, and glypican-6.
