The invention provides isolated nucleic acid and amino acid sequences of four novel G-protein coupled receptors that are amplified in breast cancer cells, antibodies to such receptors, methods of detecting such nucleic acids and receptors, and methods of screening for modulators of G-protein coupled receptors.

G-protein coupled receptors

There are disclosed methods and compositions for the diagnosis, prevention, and treatment of tumors and cancers in mammals, for example, humans, utilizing the CTSZ and CD24 genes, which are amplified colon cancer and/or ovarian cancer and/or breast cancer genes. The CTSZ and CD24 genes, their expressed protein products and antibodies are used diagnostically or as targets for cancer therapy or vaccine; they also are used to identify compounds and reagents useful in cancer diagnosis, prevention, and therapy.

Gene amplification in cancer

The present invention provides methods, reagents, and kits for diagnosing and treating cancer in a mammal, e.g., a human. This invention is based upon the discovery that G2A, GPR4, GPR65, and OGR1 are overexpressed and/or amplified in cancer. Methods to detect cancer or a propensity to develop cancer, to monitor the efficacy of a cancer treatment, and to treat cancer, by inhibiting the expression and/or activity of G2A, GPR4, GPR65, and OGR1 in a cancer cell are included.
