Scientists lay the Smac down!

From the BBC:

Cancer spreads because a gene which normally kills off cells is faulty in cancer cells.

Scientists at Cancer Research UK say they have been able to get around this problem by inserting this "suicide" gene into cancer cells.

The results were presented at Cancer Research UK's Beatson International Cancer Conference in Glasgow.

The gene that controls suicide in normal cells is called Smac.

Cancer cells have a faulty Smac gene and carry on dividing and growing well beyond their allotted lifespan.

Dr Iain McNeish and colleagues at the Cancer Research UK Molecular Oncology Unit in London used gene therapy techniques to mimic or restore the function of Smac.

Get it? "Smac down"? "Smack down"? Man, this is my best work since "Assyassination".
