ABSTRACT:
The present invention is directed to the diagnosis and treatment of diseases, preferably the inhibition of tumor growth and its progression to metastatic sites, through the inhibition of the production of PTHrP, its isoforms or PTHrP signalling. The present invention is also directed to methods of inhibiting the PTHrP1-173 isoform through antagonists thereof, including monoclonal antibodies and siRNA directed there against. The invention may be applicable to many disease states, including but not limited to several types of cancer (such as breast, lung, prostate, melanoma and squamous) expressing PTHrP and its isoforms, alone or in combination with other therapeutic agents.
