Abstract: This invention relates to modulating bone-related activity in a subject by modulating Ror molecules. The invention further relates to compositions and methods for the screening, diagnosis and development of therapies for bone-related disorders. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

Abstract: Methods of screening for agents for treating inflammatory diseases are provided. The methods involve screening for agents that modulate the activity or expression of GPR64, which has been discovered herein to play a role in inflammatory diseases. Methods for treating an inflammatory disease, as well as methods of modulating the activity or expression of GPR64, methods of screening for an inflammatory disease in a subject, pharmaceutical compositions, a nucleic acid variant, and antibodies are also provided.

Abstract: Compositions that stimulate bone formation and inhibit bone resorption through activation of both arms of EphrinB2-EphB4 signaling are provided. The composition comprises a bi-functional molecule having at least one EphB4 ligand-binding domain conjugated to an anti-EphB4 antibody.

Abstract: This invention relates to modulating Ror activity (e.g., Ror2 protein activity) and/or 14-3-3 ? to affect bone formation or resorption. The invention further relates to compositions and methods for the screening, diagnosis and development of therapies for bone-related disorders such as osteoporosis and bone fracture. Antibodies and antibody fragments directed to Ror2 protein are particularly useful in causing dimerization of Ror2 proteins, thereby leading to the activation of Ror2.
