IN THIS MONTH'S GENOME TECHNOLOGY: New Breed of Genomics Centers Works Disease-Down, Not Genes-Up
By Meredith Salisbury, Genome Technology managing editor
NEW
YORK, Aug. 13 (Genome Technology) - Sometimes it feels like there's a
new one sprouting every day. You know what we mean: the Cancer Genomics
Program at the MD Anderson Cancer Center, part of the University of
Texas. Johns Hopkins University's Program in Applied Genomics for
cardiopulmonary disease. Stanford's Asian Liver Center, using genomics
to study liver cancer among Asians.
Everywhere
you turn, there's a new center relying on functional genomics to study
one particular disease or group of diseases. What happened to Lesson
Number One in genomics history: the soup-to-nuts mega-institute shall
always prevail?
As
genomics matures, it looks like things at NIH are heading back to
business as usual: funding allocated for specific disease research, and
genomic scientists - well, really, anyone looking for grant dollars -
are finding ways to apply genomics to any range of diseases, rare or
common. Elias Zerhouni, NIH director, told his audience at the AAAS
meeting this year that he aimed to support the growing trend toward
disease-specific research.
And
why not? Such specific centers seem more likely to get funding from
illness-based foundations: a skim of places like Alzheimer's
Association; FRAXA, the Fragile X Research Foundation; and the Cystic
Fibrosis Foundation show that they're already putting money toward
genomic studies in their fields. That will certainly help make NIH's
dollar go a little further, and give more researchers the chance to
work on these diseases.
It's
too early to tell if the trend is a good one. But there are obvious
concerns about having these little centers working independently on
particular diseases. Duplicated efforts are costly, and small
institutions often don't have the resources (large sample banks, for
instance) to really come close to solving any given disease. A
potential solution comes from Lesson Number Two from genomics history:
the consortium model may save everything.
Time Is Right
Zerhouni
may be backing the trend, but that's no indication that other types of
research centers won't get funded, says Alan Guttmacher, NHGRI deputy
director. "We're early in this. It makes sense to support different
kinds of models," he says.
But
some argue that the time is right to try out this kind of initiative.
"We're starting to come into an era where a lot of what we know about
genomics can be applied to disease," says David Bowtell, director of
research at the Peter MacCallum Cancer Genomics and Genetics program in
Australia. "It's quite reasonable to take a disease focus."
Finding Focus
Guttmacher
was hardly surprised by Zerhouni's announcement this year. "NIH has
always supported disease-specific centers," he says. That's encouraged,
naturally, by the institutes' disease-specific identities. "In some
ways, this is just applying genomics to that kind of framework."
And
NIH tradition certainly has its value, points out David Altshuler of
the newly formed Broad Institute, which houses the Whitehead/MIT Center
for Genome Research. "Biological and medical research have done
extremely well in what has become the traditional model of biomedical
research," he says, adding that NIH funding history has contributed to
"the most successful [scientific] enterprise in the world."
Aside
from their goal of making progress toward a particular disease,
research at any of these centers could prove key to myriad other health
applications, Guttmacher points out. He recalls as an example a small
study on familial hypercholesterolemia - designed to examine just that
particular single-gene disease - which recovered so much information
about the cholesterol pathway that it led to the discovery of statins,
"one of the most widely used class of drugs in the country" for people
at risk of various cardiovascular diseases. Even very narrowly focused
biomedical research "tells us something about basic biology,"
Guttmacher says.
"The
concept can work if it's a really integrated center," says Michael
Liebman, director of computational biology at the Abramson Family
Cancer Research Institute at the University of Pennsylvania. He likes
the disease focus because it makes more sense from a clinical
standpoint - starting from the disease and its effect in patients and
stripping that down, layer by layer, to understanding "how genomics and
proteomics can help differentiate between subtypes of disease" - than
starting with genomics and working up from genes.
The
sense of excitement about these kinds of centers doesn't hide the
evident problems with the model. Like the early days of genomics,
pre-HGP, lots of small centers could eat up funding and never
accomplish a sweeping gesture on the order of sequencing the human
genome. "We have to be very careful that we don't duplicate things,"
says Bruce Stillman, director of the Cold Spring Harbor Laboratory and
vice chairman of a National Research Council policy board that recently
released a study on how to do large-scale biomedical research. "There
is not the amount of funding that is needed [already]."
There's
plenty of debate over how the new breed of genomics research centers
should work - including a growing community who argue in favor of the
consortium model established by the HGP. Hear from the head
honchos at some of these centers to check out different approaches to
the problem: we look at centers including the Abramson Family Cancer Research Institute, University of Pennsylvania; Asian Liver Center, Stanford University; Cancer Genomics Core Laboratory, MD Anderson; the would-be Cardiovascular Genomics Center, Boston Heart Foundation; and Peter MacCallum Cancer Genomics and Genetics to see how they're faring. Industry leaders such as Arthur Holden, CEO of the SNP Consortium, and Muin Khoury,
director of CDC's Office of Genomics and Disease Prevention, weigh in
as well. The full article appears in this month's issue of Genome Technology.
