Cancer and personalized drugs

Mon, 2010-02-22 12:58 -- John Hawks

Amy Harmon reappears in the NY Times science page this week, with a series on the clinical trials of a targeted cancer drug ("A Roller Coaster Chase for a Cure").

Dr. Flaherty, who has a near-photographic memory, was not accustomed to rereading. But in his campus office that morning, he scrolled through the article on his computer again to be sure he had understood. The presence of the same B-RAF mutation in so many cancers, he thought, meant it was one of the biggest genetic smoking guns yet identified in cancer. A drug that blocked the protein made by the defective gene might have enormous consequences for patients — and he knew of one that just might work.

This is where the "rubber" of personalized medicine "hits the road", so to speak -- if we can find drugs that treat the specific mutations that cause a person's cancer, then there may be hope in other kinds of interventions targeted to a particular genotype.

Neandertals

For years, I've worked on their bones. Now I'm working on their genes. Read more about the science studying these ancient people.

Denisova

From a finger bone of an ancient human came the record of a completely unexpected population. My lab is working on the science of the Denisova genome.

Acceleration

The advent of agriculture caused natural selection to speed up greatly in humans. We're uncovering some of the ways that populations have rapidly changed during the last 10,000 years.

Malapa

Just outside Johannesburg, the Malapa site is producing some of the most exciting finds in human evolution. This site is the headquarters of the Malapa Soft Tissue Project.
