October 11-15, 6,200 researchers and clinicians met in Montreal for the 12th International Congress of Human Genetics. After my brain recovered from the long days of meetings, one panel discussion emerged as my favorite: what I thought was going to be a dull comparison of DNA sequencing technologies turned out to be a spirited look at (more…)

It’s been a strange week. The tenth edition of my human genetics textbook was published, just as 23andMe announced that they now offer whole exome sequencing, for $999. (more…)

I’m a big supporter of animal research, but I usually keep such studies out of my textbooks, because too many times what’s true for a mouse turns out not to be true for a person. But the news from Flav Giorgini and colleagues at the University of Leicester, University of Maryland School of Medicine, and Gladstone Institutes in San Francisco is hard to ignore – and it isn’t even in mice, but my old pals fruit flies.
The science is straightforward: blocking production of an enzyme called KMO, either by knocking out its gene or feeding flies drug-laced goop, enables flies with a version of Huntington’s disease to move more normally. HD is the neurodegenerative disease that struck Woody Guthrie, causing uncontrollable, dancelike movements. Dr. Giorgini discovered the connection to KMO in yeast in 2005, using resistance against cell death as a sign, since yeast are not known to dance. And the next step is obvious – try KMO inhibitors in people. The enzyme is also implicated in Alzheimer’s disease, ALS, AIDS dementia, and a host of other common conditions.
This fly/KMO study is a perfect example of the value of animal research. And so I went onto the People for the Ethical Treatment of Animals website to see what they had to say about the value of fruit fly research. Flies are, after all, animals. I found only an outdated blog comment about a PETA-provided bug catcher, which one would presumably use to escort errant cockroaches outside. The main page featured, as usual, the adorable – dogs, monkeys, and lions – and if you search a bit, the occasional mistreated turkey or lobster. The Bambi factor is at work - protect the furry.
I'm relieved. As a former Drosophila geneticist and author of fly porn, I personally murdered millions of the little beasts, heartlessly drowning them in vats of mineral oil, or exploding their innards when I drank too much coffee before injecting them. Since then, I've lived in fear of attack by Alicia Silverstone. I guess I can keep my American Physiological Society “I’m Alive! Thanks to Animal Research!” tee shirt.
