Regulation of Apoptosis by Autophagy to Enhance Cancer Therapy.

In cancer therapy, a principle goal is to kill cancer cells while minimizing death of normal cells. Traditional cytotoxic therapies and the newer agents that target specific signaling proteins that are critical for cancer cell growth do this by activating a specific type of programmed cell death - apoptosis. However, it has been well established that cancer cells have varying levels of responses to apoptotic stimuli, with some being close to an...
