A drug which exploits the cells? own suicide mechanism has specifically targeted cancer cells in mice without harming healthy tissue, a new study shows.

The drug, which cured human lung and kidney cancers in the mice, may offer tailored treatments for individual cancer patients, the researchers hope.

Called PAC-1, the drug converts a dormant protein called procaspase-3 into its active form, an ?executioner? protein called caspase-3, which consigns the cell to death. In previous lab-based studies, the team has shown that PAC-1 successfully kills off a whole range of cancers, provided they are rich in procaspase-3.

good luck to them. I hope they dont have many bad side effects on humans. The big C is one of the most scariest things to happen to humans.

Great! My great-grandmother died of lung cancer and I hope that this works for other people!
