ABSTRACT:
The present invention relates to a method of identifying a compound (agent) which modulates apoptosis in transformed cells. In one embodiment, the invention is a method of identifying a compound which selectively activates apoptosis in transformed cells. In an alternative embodiment, the present invention can be used as a method of identifying a compound which inhibits apoptosis in cells. The invention also relates to a method of selectively killing transformed cells, wherein the transformed cell is contacted with a compound which selectively activates apoptosis in transformed cells, as described herein. The invention also relates to methods of treating diseases associated with defective apoptotic machinery (e.g., cancer, neurodegenerative disease). The methods of the present invention are useful for defining the biochemical mechanisms of apoptosis. In addition, the invention provides an assay to identify compounds which modulate (inhibit, activate) apoptosis, supplying new drugs which target defective apoptotic machinery associated with disease (e.g., cancer, neurodegenerative diseases such as Huntington's Disease and Alzheimers Disease).
