The 2007 Nobel Prize in Physiology or Medicine
Mario Capecchi, Martin Evans and Oliver Smithies share the 2007 Nobel Prize in Physiology or Medicine for the development of gene targeting in mice, which made possible the discovery of numerous gene functions and the creation of many mouse models for human diseases.

The Nobel Prize in Physiology or Medicine was announced early October 8th. The winners were Mario Capecchi of the University of Utah, Martin Evans of Cardiff University and Oliver Smithies from the University of North Carolina at Chapel Hill. The won for their discoveries leading to gene targeting in mice.
Gene targeting allows researchers to inactivate individual genes. By the gene’s absence, its true function is often revealed. Numerous genes involved in health and disease have been found using gene targeting. And researchers can knock out specific genes to create mouse models of human diseases, including diabetes and cancer. More than 500 such mouse models have been created.
Capecchi discovered genes crucial for mammalian organ development and the body plan in general. That work has revealed the causes of several birth defects. Evans developed models for the disease cystic fibrosis. And Smithies created mouse models for hypertension and atherosclerosis.

It’s Time to Stand Up for Science
If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.
I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.
If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.
In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.
There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.
