Gene Conversation
An interview with pioneering geneticist Dr. Janet Rowley
By CORY FRANKLIN M.D.
Dr. Janet Rowley, professor of medicine at the University of Chicago,
is, if you’ll excuse the cliché, a living legend. She is indisputably
one of America’s greatest physician/researchers of the post World War
II era, an accolade acknowledged last year when President Barack Obama
awarded her the Presidential Medal of Freedom, the country’s highest
civilian honor.
Her most important work has been in genetics and cancer. She
discovered the link between specific chromosomal translocations with
different types of leukemia. (Translocations are breaks in the DNA of
chromosomes with an abnormal rejoining of the broken parts.) One of
the truly groundbreaking discoveries in 20th century medicine and based
on her research, leukemia patients who formerly would have died are now
treated successfully and are “cured” or have long term remissions.
Moreover, her discovery of the relationship between chromosomal
abnormalities and cancer promises to have profound future implications
as scientists unlock the secrets of the human genome.
For her work, Dr. Rowley has received other notable awards,
including the Lasker Award, the National Medal of Science and the
Gruber Prize in Genetics, three of the most prestigious honors in
science. She recently received the seventh annual American Association
for Cancer Research Award for Lifetime Achievement in Cancer Research
in Washington, DC.
Her time at the University of Chicago—from high school and medical
school to faculty—has spanned 70 years. It would be no exaggeration to
call her the First Woman of Medicine in Chicago. Despite her
considerable accomplishments, she was particularly humble and
self-effacing in this interview.
What do you see for the future of genetic medicine? I’m not as
pessimistic as some. I think the future is very bright. It will take
some time, five years or more, to figure out how to use genetic mapping
effectively, at least in cancer medicine. We do know of several
mutations in cancer cells that are not found in regular cells, and
these present attractive targets for therapy. We just don’t know how to
exploit these targets yet. We were fortunate with chronic myeloid
leukemia (the discovery she contributed to), but other targets aren’t
as easy to treat effectively. If we understand the genetic abnormality,
and we are lucky, genetic medicine will be great and lead to remarkable
new therapies.
One controversial area is whether private companies should be able to
privatize, or essentially own, a gene. How do you feel about that?
Recently a judge ruled a private company couldn’t hold a patient on an
important gene that predisposes to breast and ovarian cancer. But it’s
not a simple problem. One should avoid a knee-jerk response that all
patenting is bad. In some cases, licensing may be a better approach.
It’s easy to say you are against patenting, but at the same time, we
need a mechanism to exploit new genetic discoveries in patients. The
way mankind is motivated, there has to be some type of incentives for
businesses. Risk-takers must be rewarded in some way for performance.
We must figure out ways to be smart and wise so that important genes
and mutations do not become orphans.
Another controversial area is excessive pharmaceutical company profits
from these discoveries. Any thoughts?
There are situations where the
companies are making billions of dollars in profits on drugs from
scientific discoveries. I’m not really in favor of that. They are
certainly entitled to a fair profit, but patients must have access to
these therapies. There is room for a fair profit while assuring access
without bankrupting the patient or the system.
Is there still a role for the individual investigator?
There will always be a role for the individual investigator, the scientific
entrepreneur, as it were. But more and more the future of medicine will
require the collaboration of scientists with different skills. In the
future, scientists will have to cooperate, collaborate and sublimate
their egos, along with those of their colleagues, in order to make
valuable scientific contributions.
What advice do you have for young people going into science today?
First and foremost, don’t give up. I didn’t do anything noteworthy in
my career until I was 50. Take risks, do something different if it
looks interesting. I got out of clinical medicine for what was supposed
to be a year when I was younger to pursue research, and it wound up
changing my career. Finally, success often involves a great deal of
luck. Some people don’t like to hear that because it means there are
things out of their control. But that’s the way it is.
