Abstract
The invention relates nucleic acids and their encoded polypeptides, whose expression is modulated in cancer or tumor cells. The invention further relates to methods useful for treating or modulating cancer or tumors in mammals in need of such biological effect. This includes the diagnosis and treatment of oncological disorders. Additionally, the present invention further relates to the use of antibodies against the polypeptides of the present invention as diagnostic probes or as therapeutic agents as well as the use of polynucleotide sequences encoding the polypeptides of the present invention as diagnostic probes or therapeutic agents for the treatment of a broad range of pathological states.

9. A method of identifying an agent that binds to p-cadherin comprising:
-
(a) contacting p-cadherin with said agent; and
(b) determining whether said agent binds to p-cadherin.
-
-
10. A method for identifying an agent that modulates the expression or activity of p-cadherin comprising:
-
(a) providing a cell expressing said polypeptide in an operational manner;
(b) contacting the cell with said agent; and
(c) determining whether the agent modulates expression or activity of said polypeptide;
whereby an alteration in expression or activity of p-cadherin indicates said agent modulates expression or activity of p-cadherin.

12. A method of detecting differentially expressed genes correlated with a cancerous state of a mammalian cell, the method comprising the step of detecting at least one differentially expressed gene product in a test sample derived from a cell suspected of being cancerous, where the gene product is encoded by a sequence of SEQ ID NO:
- 1 wherein detection of differentially expressed product is correlated with a cancerous state of the cell from which the test sample was derived.
-
13. A method for monitoring the progression of a cancer in a patient, the method comprising:
-
a) detecting in a patient sample at a first point in time, the expression of a marker, wherein the marker a nucleic acid molecule of SEQ ID NO;
1;
b) repeating step a) at a subsequent point in time; and
c) comparing the level of expression detected in steps a) and b), and therefrom monitoring the progression of the cancer.

14. A method of assessing the efficacy of a test compound for inhibiting a cancer in a patient, the method comprising comparing:
-
a) expression of a marker in a first sample obtained from the patient exposed to the test compound, wherein the marker is selected the nucleic acid molecule of SEQ ID NO;
1, andb) expression of the marker in a second sample obtained from the patient, wherein the sample is not exposed to the test compound, wherein a significantly lower level of expression of the marker in the first sample, relative to the second sample, is an indication that the test compound is efficacious for inhibiting the cancer in the patient.
