Methods of increasing bone mass in a subject comprising inhibiting DKK1
The present invention is drawn to understanding lytic bone diseases. In this regard, the present invention discloses mechanism by which Wnt signaling antagonist inhibits bone differentiation. Also disclosed herein are methods to control bone loss, treat bone disease and prevent tumor growth in bones of individual.
1. A method of increasing osteoblast activity in a subject exhibiting increased DKK1 activity or expression, comprising the step of:
administering to the subject an agent that is a DKK1 neutralizing antibody that binds a DKK1 protein consisting of the sequence encoded by the DKK1 gene consisting of the sequence shown in SEQ ID No: 47, wherein the agent inhibits the activity of the DKK1 protein.
2. A method of inhibiting osteoclast activity in a subject, exhibiting increased DKK1 activity or expression, comprising the step of:
administering to the subject an agent that is a DKK1 neutralizing antibody that binds a DKK1 protein consisting of the sequence encoded by the DKK1 gene consisting of the sequence shown in SEQ ID No: 47, wherein the agent inhibits the activity of the DKK1 protein.
3. A method of increasing bone mass in a subject, exhibiting increased DKK1 activity or expression, comprising the step of:
administering to the subject an agent that is a DKK1 neutralizing antibody that binds a DKK1 protein consisting of the sequence encoded by the DKK1 gene consisting of the sequence shown in SEQ ID No: 47, wherein the agent inhibits the activity of the DKK1 protein.
