A major medical breakthrough out of St. Louis is an uplifting development for Missouri, a state that too often makes news for its attempts to limit scientific research.

Scientists at Washington University in St. Louis report that they decoded all the genes of a leukemia patient and identified mutations that may have caused or aided the disease. The first-ever genetic map of DNA taken from cancer cells moves medicine a step closer to “personalized genomics.”

Richard K. Wilson, director of Washington University’s Genome Sequencing Center, described a scenario in which scientists may be able to quickly analyze a patient’s DNA sequencing and recommend drug therapy to combat the particular mutations.

And more genetic decoding—made easier and less expensive by recent technological advances—will provide important clues about what happens in cells when cancer takes hold and progresses.

Prominent researchers are heralding the breakthrough. A cancer specialist at Memorial Sloan-Kettering Cancer Center in New York described it in The New York Times as a “tour de force.”

Bill Neaves, chief executive officer of the Stowers Institute for Medical Research in Kansas City, said the discovery “highlights the pioneering role of Washington University … in the search for smarter ways of treating a cancer patient’s particular disease.”

The Stowers Institute also is engaging in gene-based research with the goal of developing therapies tailored to individual patients, Neaves said.

“It is gratifying to see the first comprehensive sequencing of a cancer patient’s genome occur here in Missouri,” he said.

Yes it is. After the destructive attempts to ban a form of embryonic stem cell research in the state, it is profoundly satisfying to see Missouri emerge as the site of a breakthrough.

The good news out of St. Louis is all the more reason for the Missouri legislature and Governor-elect Jay Nixon to strengthen the state’s support for higher education and scientific research.
