URBANA -- Endometriosis is a
condition that afflicts 10 percent of U.S. women, causes infertility
and pain, and presently has no effective treatment. Romana Nowak, an
associate professor of reproductive biology in the University of
Illinois's Department of Animal Sciences, is focusing on a special
protein that may play a key role in the disease.
Nowak's work is funded by a
National Institutes of Health
grant for women's reproductive health.
"We're looking at a special protein
that regulates uterine cells," she said. "In endometriosis, cells
that are normally discharged from the uterus end up going the wrong
way and getting into the body cavity. They attach themselves to the
body wall or to organs and create areas of localized inflammation.
Enzymes called metalloproteinases secreted by the uterine cells
allow these cells to invade the body wall and groin."
This can lead to widespread pain and
possibly fertility problems in the women affected.
"Right now, there are not a lot of good
treatments for it," she said. "Surgery is one option, but the
disease tends to come back. The drug treatments that are presently
available have some success but also carry side effects and do not
permanently eliminate the disease."

Nowak is focusing on emmprin, a protein
that has been shown to regulate the production of metalloproteinases
by uterine cells.
"We hope if we can find some way to
regulate emmprin, we might be able to prevent endometriosis from
occurring," she said.
still in the early stages of the five-year grant. Three other U of I
researchers in the College of Medicine, which shares the NIH grant,
are exploring other mechanisms of endometriosis. These researchers
are Dr. Asgi Fazleabas, Dr. Serdar Bulun and Dr. Geula Gibori.
