A system and device are provided which include a gene regulatory system controlling expression of one or more expression cassettes present in or released by the device, by emitting one or more stimulations. An expression cassette includes a regulatable transcription control element that is responsive to the emitted stimulations linked to an open reading frame of interest. The system optionally includes a sensor to sense a parameter indicative of a need, a telemetry module to receive an external command, or a programmable device, for regulating gene expression of the open reading frame.
The present invention relates to compositions and methods for cancer diagnostics and therapeutics, including but not limited to, HIP1 cancer markers. In particular, the present invention provides compositions and methods of using HIP1 in the diagnosis and treatment of epithelial cancers. The present invention thus provides improved compositions and methods for diagnosing and treating some of the most common cancers (e.g., prostate and colon cancers). The present invention additionally provides drugs active against HIP1 and methods for screening for such drugs.
