Mapping the cancer genome

New York Times: Medical science is a littler closer to understanding a dread disease thanks to a new found ability to map the "cancer genome."

The new research, by looking at the entire genome — all the DNA —and aiming to find all the mutations involved in a particular cancer, differs markedly from earlier studies, which have searched fewer genes for individual mutations. The project, which took months and cost $1 million, was made possible by recent advances in technology that have made it easier and cheaper to analyze 100 million DNA snippets than it used to be to analyze 100.

The study was done at Washington University in St. Louis and is being published Thursday in the journal Nature. It is the first report of a “cancer genome,” and researchers say many more are to come.
