Gene Stops Tumors, but Only When It’s Gone
December 2nd, 2009
There are times when nothing at all is better than a half measure.
One of those times is when a cell becomes cancerous. The loss of one copy of a regulatory gene called DICER1 is enough to turn tumors deadly, while losing both can actually stop cancer, shows a new study led by researchers at MIT. The discovery, published online November 10 in Genes & Development, suggests that many other genes working at half capacity may also accelerate tumor growth.
