Bone morphogenetic protein antagonist and uses thereof
The present invention relates to the use of proteins that are differentially expressed in tumor associated stromal cells, as compared to normal stromal, as biomolecular targets for tumor treatment therapies. The present invention also provides compounds and pharmaceutically acceptable compositions for administration in the methods of the invention.
1. A method for the detection of a tumor-associated stromal cell, the method comprising:
detecting the level of expression of Gremlin 1 mRNA or protein in candidate tumor-associated stromal cells;
comparing the level of expression of Gremlin 1 mRNA or protein in said candidate tumor-associated stromal cells to normal stromal cells, wherein increased levels of expression of Gremlin 1 in said candidate tumor-associated stromal cells is indicative that said cells are tumor-associated stromal cells.
2. The method according to claim 1 , wherein increased amounts of Gremlin 1 mRNA are detected in said candidate tumor associated stromal cells.
3. The method of claim 1 , wherein the tumor is a carcinoma.
4. The method of claim 1 , wherein said increased amounts of Gremlin 1 polypeptide are detected in said candidate tumor associated stromal cells.
