From ScienceDaily, an article on an elegant class of potential cancer therapies. This is a good example of what can be achieved with a greater understanding of biochemistry: existing mechanisms hooked together to produce a controlled biological system that attacks only cancer cells and can be turned on and off as needed. "[An antibody currently in clinical use], with the attached alliinase in tow, soon found and bound to the target cancer cells. Subsequently, the mice were repeatedly injected with the inert chemical alliin which, upon contact with alliinase, was processed into allicin molecules directly on the cancer cell's surface. Within three days, almost all of the human lymphoma cancer cells were destroyed in those mice."
