Methods for identifying anti-cancer drug targets

Methods, transformation constructs, and transgenic animals for identifying anti-tumor agents and anti-tumor drug targets are described. The transformation constructs are used to generate transgenic animals that have altered expression of an oncogene or tumor suppressor gene in a target tissue that is dispensable for viability and reproduction. In some embodiments, the altered expression results in abnormal proliferation of the target tissue and normal proliferation in all other tissues. Anti-tumor drug targets can be identified by generating progeny of the transgenic animals that have mutations in various genes. Gene mutations that result in a specific reduction or killing of the target tissue are identified as possible anti-tumor drug targets and are further evaluated. Anti-tumor agents are identified that mimic the effect of the gene mutations that result in specific reduction of the target tissue. Alternatively, anti-tumor agents can be identified by administering various compounds directly to the transgenic animals, or their progeny, and selecting as putative therapeutic agents, compounds that result in target-tissue specific antiproliferation.
