Medical Xpress / Light-activated protein triggers cancer cell death by raising alkalinity

One of the hallmarks of cancer cells is their ability to evade apoptosis, or programmed cell death, through changes in protein expression. Inducing apoptosis in cancer cells has become a major focus of novel cancer therapies, ...
