Abstract
Methods of detecting synovial sarcoma using differentially expressed genes are disclosed. Also disclosed are methods of identifying agents for treating synovial sarcoma. Further, a method for treating or preventing a disease that is associated with Frizzled homologue 10 (FZD10) in a subject is provided.
Claims14
A method of identifying an agent that inhibits the expression of FZD 10 protein, comprising:
- (a) contacting a test sample expressing a polypeptide comprising FZD 10 protein with a test agent;
- and
- (b) determining the expression level of a polypeptide comprising FZD 10 protein with an antibody which binds to a peptide consisting of residues 43-56, 61-72, 156-169, 157-170, 157-172, 161-173, 174-191, 189-202, or 214-225 of SEQ ID NO:
- 153,
- wherein a decrease of the level compared to a normal control level of the protein indicates that the test agent is an inhibitor of FZD 10 protein.
A method of screening for a compound that binds FZD 10 protein in synovial sarcoma, comprising:
- (a) contacting a test compound with a polypeptide comprising FZD 10 protein;
- (b) detecting the binding activity of the test compound to the FZD 10 protein with an antibody which binds to a peptide consisting of residues 43-56, 61-72, 156-169, 157-170, 157-172, 161-173, 174-191, 189-202, or 214-225 of SEQ ID NO:
- 153;
- and
- (c) selecting the compound that binds to the protein of (a).
A composition for treating synovial sarcoma, wherein the composition comprises a pharmaceutically effective amount of an antibody as an active ingredient, and pharmaceutically acceptable carrier, wherein said antibody is obtained by a screening method that screens for antibodies for treating synovial sarcoma that comprises contacting a test antibody with a peptide consisting of amino acid residues 43-56, 61-72, 156-169, 157-170, 157-172, 161-173, 174-191, 189-202, or 214-225 of SEQ ID NO:
- 153, detecting the binding activity of the test antibody to said amino acid residues to the polypeptide and then selecting the antibody that binds to the polypeptide with said amino acid residues.
A method for diagnosis of synovial sarcoma, comprising:
- (a) contacting a sample from the subject with an antibody raised against a peptide comprising amino acid residues 43-56, 61-72, 156-169, 157-170, 157-172, 161-173, 174-191, 189-202, or 214-225 of SEQ ID NO:
- 153 or a fragment of said antibody;
- (b) detecting the FZD 10 protein in the sample;
- and
- (c) diagnosing whether or not the subject suffers from synovial sarcoma based on the relative abundance of the FZD 10 protein compared to a control.
A pharmaceutical composition for treating synovial sarcoma, comprising an antibody or a fragment that is raised against a peptide consisting of amino acid residues 43-56, 61-72, 156-169, 157-170, 157-172, 161-173, 174-191, 189-202, or 214-225 of SEQ ID NO:
- 153, and a pharmaceutically acceptable carrier or excipient.
A kit for diagnosis of synovial sarcoma, comprising an antibody or a fragment that is raised against a peptide consisting of amino acid residues 43-56, 61-72, 156-169, 157-170, 157-172, 161-173, 174-191, 189-202, or 214-225 of SEQ ID NO:
- 153.
A composition for treating synovial sarcoma, wherein the composition comprises a pharmaceutically effective amount of an antibody as an active ingredient, and a pharmaceutically acceptable carrier, wherein said antibody is raised against a peptide consisting of amino acid residues 43-56, 61-72, 156-169, 157-170, 157-172, 161-173, 174-191, 189-202, or 214-225 of SEQ ID NO:
- 153.
A composition for treating synovial sarcoma, wherein the composition comprises a pharmaceutically effective amount of an antibody as an active ingredient, and pharmaceutically acceptable carrier, wherein said antibody is obtained by a screening method that screens for antibodies for treating or preventing synovial sarcoma that comprising:
- contacting a test antibody with a peptide consisting of amino acid residues 43-56, 61-72, 156-169, 157-170, 157-172, 161-173, 174-191, 189-202, or 214-225 of SEQ ID NO:
- 153,
- detecting the binding activity of the test antibody to the polypeptide;
- and
- selecting the antibody that binds to the polypeptide.
A composition for treating synovial sarcoma, wherein the composition comprises an antibody as an active ingredient, and said antibody binds to a peptide consisting of residues 43-56, 61-72, 156-169, 157-170, 157-172, 161-173, 174-191, 189-202, or 214-225 of SEQ ID NO:
- 153, and a pharmaceutically acceptable carrier or excipient.
