Amplified oncogenes and their involvement in cancer

摘要

There are disclosed methods and compositions for the diagnosis, prevention, and treatment of tumors and cancers in mammals such as humans, utilizing the Galanin, Galanin Receptor 2 (GALR2) and Galanin Receptor 3 (GALR3) genes, which are amplified in breast and/or lung and/or brain and/or colon and/or prostate and/or ovarian cancer genes. The Galanin, GALR2 and GALR3 genes and their expressed protein products and antibodies are used diagnostically or as targets for cancer therapy or vaccine; they are also used to identify compounds and reagents useful in cancer diagnosis, prevention, and therapy. There is also disclosed a GALR2-GALR3 heterocomplex formation during tumorigenesis.
