Rogue gene discovery could brake cancers

Paris: Scientists on Monday said their discovery of a "rogue gene" could stop the spread of most late-stage cancers, providing one day the right drug is found.

Known as WWP2, the gene controls an enzyme which attacks a natural inhibitor that prevents cancer cells from spreading.

Researchers at the University of East Anglia in eastern England found that by blocking the action of WWP2, levels of this inhibitor are boosted and cancer cells cannot reproduce.

Lead author Andrew Chantry said that the work threw open new avenues of investigation into stopping metastatis, or when cancer starts to spread aggressively, especially in breast, brain, colon and skin tissues.

"The challenge now is to identify a potent drug that will get inside cancer cells and destroy the activity of the rogue gene," said Chantry.

"This is a difficult but not impossible task, made easier by the deeper understanding of the biological processes revealed in this study."

If such a drug were found, conventional therapies and surgery could be used on primary tumours without the risk that the disease could spread elsewhere.

The lab-dish breakthrough came in a probe of a group of cancer-cell inhibitors called "Smads."
