Abstract: The present invention relates generally to chemical-inducible system and to methods of use in transgenic animals. More specifically, the present invention relates to a chimeric transcription factor that binds to a ligand and functions in ligand-dependent manner to induce expression of genes of interest under the control of a synthetic operator-promoter sequence. The expression of genes of interest can be tightly controlled by adding or removing the ligand.

Abstract: The present invention is directed to fish whose genome has integrated therein an oncogenic nucleic acid operably linked to a promoter. Methods of making the fish and methods for their use are also provided. The fish may advantageously be utilized in methods of screening for drugs or agents that modulate oncogene-mediated neoplastic or hyperplasic transformation, or that modulate sensitivity to chemotherapy or radiation therapy. Immortal tumor cells lines, methods of making immortal tumor cells lines and methods of their use are also provided.
