AN UPDATE FOR PARTNERS OF THE CHILDREN'S DISCOVERY INSTITUTE SPRING 2013 ChildrensDiscovery.org IMPROVING PREGNANCY-RELATED HEALTH OUTCOMES A unique initiative provides samples and data for studies on women’s reproductive health and pediatric diseases Three years ago, the Children’s Discovery Institute launched a one-of-a-kind initiative called the Women and Infants’ Health Specimen Consortium (WIHSC). Its aim is to track long-term, pregnancy-related health outcomes of women and their infants by collecting, processing and storing clinical samples taken from women before and during pregnancy, as well as samples from infants after delivery.

IMPROVING PREGNANCY-RELATED HEALTH OUTCOMESA unique initiative provides samples and data for studies on women’s reproductive health and pediatric diseases ›

Three years ago, the Children’s Discovery Institute launched a one-of-a-kind initiative called the Women and Infants’ Health Specimen Consortium (WIHSC). Its aim is to track long-term, pregnancy-related health outcomes of women and their infants by collecting, processing and storing clinical samples taken from women before and during pregnancy, as well as samples from infants after delivery.

In addition to the samples, a comprehensive database of clinical outcomes from the WIHSC is available to the Washington University research community to study women’s reproductive health and pediatric diseases.

“The WIHSC is the only large tissue and biomedical information database in the United States that collects samples from women at different time points—during conception, throughout pregnancy and beyond,” says lead investigator Kelle Moley, MD, the James P. Crane Professor of Obstetrics and Gynecology at Washington University School of Medicine. “This consortium enables studies that probably weren’t possible before because we didn’t have access to these samples.”

By providing a vast resource of blood, urine, amniotic fluid and placenta tissue samples, as well as infant brain development data, the WIHSC can help scientists pinpoint factors that cause premature birth, such as high blood pressure in pregnant women, poor fetal growth, fetal chromosomal abnormalities, congenital heart disease, miscarriage, infertility and poor outcomes related to assisted reproductive technology. Ultimately, this research can lead to new diagnostic tools and treatment strategies for a range of pregnancy-related health conditions.

“The possibilities are endless,” Dr. Moley says. “This resource could help us develop predictors for pregnancy outcomes such as preterm birth, or understand the

fetal origins of adult diseases.” For this project, Dr. Moley is collaborating with Ann Gronowski, PhD, professor of pathology and immunology at the School of Medicine, and Marwan Shinawi, MD, associate professor of pediatrics at the School of Medicine.

Having recently expanded from recruiting patients and obtaining samples at one clinic to four centers, the WIHSC has enrolled more than 2,500 patients, including 500 infants, and banked more than 15,000 specimens.

Recent Studies Showcase Wide-Ranging Research AdvancesAs the Children’s Discovery Institute embarks on its seventh year of funding innovative research to promote children’s health, I am continually impressed by the far-reaching accomplishments of the Institute’s talented investigators. Here are just a few of the recent published studies that deserve mentioning.

Two of these studies, published in Science and Nature, highlight the importance of sequencing the genomes of microbial communities to understand their impact on human health. For example, Gautam Dantas, PhD, and his team revealed that bacteria found in soil could transfer genes that cause antibiotic resistance to pathogens responsible for pneumonia and other life-threatening infections, making these conditions more difficult to treat. On the other hand, Barbara Warner, MD, and her collaborators showed that microbial communities in the intestinal tract vary significantly between people in different countries. This could explain how cultural factors such as diet could lead to different health outcomes across geographic locations.

As reported in Nature and Cancer Research, Joshua Rubin, MD, PhD, Jeffrey Leonard, MD, and their collaborators are making substantial progress in understanding medulloblastoma, the most common malignant brain tumor in children. By characterizing unique molecular and genetic patterns in different subgroups of medulloblastoma patients, these researchers will pave the way for personalized treatment plans for specific types of patients.

Beyond improving therapeutic options for patients, it is crucial to develop new tools to improve the diagnosis of diseases. Toward that end, Charles Canter, MD, Samuel Wickline, MD, and colleagues developed a noninvasive imaging method for detecting transplant coronary artery disease — the main complication that limits long-term survival in pediatric heart transplant recipients. This approach, reported in the Journal of Heart and Lung Transplantation, will help clinicians decide on the best treatment options for these patients.

Taken together, these new research advances illustrate the important work that Institute investigators continue to pursue in order to treat, cure and ultimately prevent a wide range of childhood diseases.

The Children’s Discovery Institute’s Fifth Annual Symposium gave investors the opportunity to learn about research advances from a selection of Institute-funded projects.

Kicking off the first session, Beth Kozel, MD, PhD, discussed her research on genetic factors that influence the severity of vascular disease in patients with Williams syndrome. These patients are prone to high blood pressure and stiff blood vessels. She has used mice to model these vascular problems and identify several genes that modify the severity of vascular disease. She also has confirmed that variation in one of these genes influences the severity of high blood pressure and vascular stiffness. Her talk highlighted the importance of using both animal models and human studies to pinpoint the genetic causes of human diseases. Ultimately, the research could help doctors predict which children will develop life-threatening vascular disease, and use this information to develop more effective, individualized strategies for clinical interventions. After the presentation, Dr. Kozel showcased instruments used for her research, including a vascular probe and a machine that measures the skin’s elasticity.

Armed with a container of brain tumor samples, the second presenter, Joshua Rubin, MD, PhD, discussed his research on factors that affect the risk of developing pediatric brain tumors. Boys have a higher rate of brain tumors than girls. To try to understand why, Dr. Rubin is studying brain tumors associated with neurofibromatosis 1 (NF1) — the most common genetic disease associated

Symposium participants peer through a microscope to get a better understanding of the genetic connection between humans and zebrafish. Yes, zebrafish.

with childhood brain tumors. Using a mouse model of NF1-associated brain tumors, Dr. Rubin has found that a molecule called cyclic AMP, which is important for the development of brain tumors, is regulated in different ways in the brain cells of males versus females. In humans, Dr. Rubin has found that genetic variations regulating cyclic AMP levels can account for gender differences in the risk of developing brain tumors. Moving forward, it will be possible to develop a screening tool to identify patients at risk for brain cancer prior to the onset of symptoms, and use this information to personalize clinical care. Ultimately, this research could lead to new strategies to prevent and treat brain cancer.

In the next session, Steven Brody, MD, showcased lung samples while discussing the importance of using cultured airway epithelial cells to study childhood lung diseases, such as asthma, cystic fibrosis and respiratory virus infection. The Airway Epithelial Cell Core provides Institute investigators with complex preparations of cells taken from the respiratory tracts of mice and humans; a repository of normal and diseased lung tissue; and technical training in methods for generating, maintaining and analyzing these high-quality cell preparations. This state-of-the-art resource enables researchers to better understand lung biology and develop new therapeutic strategies for diseases.

Christina Gurnett, MD, PhD; Matthew Goldsmith, MD; and Ryan Gray, PhD, presented their research on the genetic basis of scoliosis. They explained the advantages of using zebrafish—which were on display for investors to see—as an animal model for this condition. These tropical fish can develop curves in the spine, just like humans, and the genes involved in their development are similar to

those found in humans. By introducing mutations randomly into the zebrafish genome, the researchers have identified genes responsible for spinal curves. Moving forward, they will determine how these mutations cause spinal curves and will use these animals to screen for drugs that could correct the problem. They also have collected DNA samples from 500 patients with scoliosis and are performing gene sequencing to determine their genetic risk factors. Ultimately, their research could lead to the development of more effective diagnostic tools and preventive treatments. ›

Joshua Rubin, MD, PhD, lets investors get up close and personal with the brain tumors he uses in his research on factors that affect a child’s risk for developing these tumors.

Faculty scholar awardee gets to the bottom of antibiotic-resistant Staph infections

It has long been known that methicillin-

resistant Staphylococcus aureus (MRSA)

— a type of Staph bacteria that is

resistant to treatment with many common

antibiotics — often takes up residence

in hospitals, putting hospital patients

at risk. But over the past 15 years, this

pathogen has found its way into people’s

homes as a new strain easily transmitted

from person to person. Nearly 2 percent

of individuals in the United States have

MRSA living in their noses or on their

skin (also known as colonization). This

can cause pneumonia and other serious

infections. MRSA also is the most

frequent cause of skin infections and

invasive, life-threatening infections

of the muscles and bones in children.

Community-associated MRSA can be curbed through good hygiene, covering cuts with bandages and washing sheets and towels in hot water. But effective methods for reducing MRSA colonization, interrupting the spread of MRSA and preventing infections are still lacking. “We have a lot of non-evidence-based recommendations that we give our patients to try to prevent recurrent infections, but we don’t know how well they work,” says Stephanie Fritz, MD, MSCI, assistant professor of pediatrics at Washington University School of Medicine. “We are trying to put the science behind the recommendations we make to our patients.”

With the help of a faculty scholar award from the Children’s Discovery Institute, Dr. Fritz is studying how MRSA spreads in the community, specifically within households, where infections tend to cluster. By following 150 pediatric patients with community-associated MRSA infection and their household contacts for one year, she is learning how family

members transmit MRSA to one another. Dr. Fritz samples household surfaces, such as countertops and television remote controls. She also surveys family members about places they visit that could expose them to the pathogen, as well as their hygiene practices, such as sharing towels.

“To date, studies have not been published which examine the transmission dynamics of Staph in the household, and right now people are very much at a loss for how to prevent these infections,” Dr. Fritz says.

“This study takes a thorough, whole-house approach to answer these questions. Our goal is to identify the environmental surfaces in the household that might be playing a key role in transmission. Then we’ll be able to focus our interventions on those targets and develop better preventive strategies.”

Dr. Fritz also will take DNA samples from these individuals and study the DNA of the germs they carry to determine which genetic factors increase susceptibility to MRSA and severe infections. For instance, differences in genes that regulate immune responses in individuals could affect their ability to fight infections, while genetic differences among Staph strains could influence their virulence. “Right now, we don’t have a vaccine to prevent Staph infections, and it’s not well known what the targets should be for a vaccine. The information we are assembling could help us develop a vaccine, and certainly could help us decide who should receive a vaccine,” Dr. Fritz says. “For example, knowing more about who is most susceptible to these invasive infections will help us decide who should be immunized and who should receive more aggressive therapy.”

Based on preliminary data collected through this Institute-funded project, Dr. Fritz has been awarded a $2.5 million grant from the U.S. Department of Health & Human Services’ Agency for Healthcare Research and Quality. “The Children’s Discovery Institute has been essential for allowing junior investigators to launch our research programs,” she says. “We often have very creative ideas that may not be mainstream enough for traditional funding agencies. Very fruitful, innovative and exciting research funded by the Institute really helps us provide the most up-to-date care for pediatric patients.” ›

Determining the origins of metabolic syndrome could lead to healthier kids

Obesity is an epidemic among children and adolescents in the United States, and for the first time in centuries, it threatens to make their life expectancy shorter than that of their parents.

Nearly one in five children and adolescents are obese, putting them in danger of developing metabolic syndrome, a cluster of conditions that increases the risk for heart disease and other health problems, including diabetes and stroke. Children with metabolic syndrome have at least four risk factors: excessive belly fat, high blood pressure, high cholesterol and high blood sugar.

Factors that increase a child’s risk for obesity traditionally have been thought to be limited to lifestyle choices, such as diet and exercise. But this may not always be the case. Instead, obesity and its health complications also may stem from conditions in the womb.

“Metabolic syndrome is a major public health problem, but not many studies have focused on its origins,” says Carlos Bernal-Mizrachi, MD, assistant professor of medicine and cell biology and physiology at Washington University School of Medicine.

“The objective of my research is to try to identify environmental conditions or other factors in the womb that affect the development of metabolic syndrome.”

Dr. Bernal-Mizrachi focuses on vitamin D and its role in immune system function, which in turn influences the development of metabolic syndrome. Many pregnant women have vitamin D deficiency. These women often give birth to children who eventually become obese and develop metabolic syndrome.

“There are many trials indicating that vitamin D may be fundamental during pregnancy and the early postnatal period to prevent or ameliorate the development of metabolic disorders,” Dr. Bernal-Mizrachi says.

In past research, Dr. Bernal-Mizrachi has identified potential mechanisms by which vitamin D regulates immune cell responses and the development of cardiovascular disease. That has laid the groundwork for clinical trials assessing the benefits of vitamin D supplementation. He has recently discovered that vitamin D deficiency in mice causes an increase in blood pressure and hardening of the arteries and alters immune cell responses — patterns associated with metabolic syndrome.

With the support of the Children’s Discovery Institute, he is now turning his attention to the influence of vitamin D deficiency on the genetics of immune cells in the womb and how this contributes to the

development of metabolic syndrome after birth. So far, he has found that mice genetically engineered to lack the vitamin D receptor in immune cells have metabolic abnormalities resembling those caused by vitamin D deficiency in the womb. In collaboration with Washington University’s Ting Wang, PhD, assistant professor of genetics, and Mark Sands, PhD, professor of medicine, Dr. Bernal-Mizrachi is identifying specific genes and tissues that are affected by vitamin D deficiency during embryonic development. These genes and tissues could play a role in the development of metabolic syndrome. “Without the Children’s Discovery Institute, I would not have been capable of progressing in this research,” Dr. Bernal-Mizrachi says.

Through this interdisciplinary research initiative, Dr. Bernal-Mizrachi hopes to provide firm evidence for the importance of vitamin D supplementation during pregnancy and uncover potential targets for drugs that could prevent and treat obesity and metabolic syndrome, paving the way for clinical trials.

“These findings could potentially change the way we look at metabolic syndrome. There are major health implications, because there are potentially ways to resolve it,” he says. “One potential way is to improve vitamin D supplementation, but this may not be the whole story. If we can understand the environmental conditions that play a role early on, we can come up with other strategies for intervention.” ›

Funding Update ›

As a retired chief executive officer of a utility company and an original board member of the Children’s Discovery Institute, Chuck Mueller sees the value of a team-based approach to finding cures for pediatric diseases. That’s why he and his wife, Jan, are enthusiastic supporters of the Institute.

Q: How did you become involved in the Children’s Discovery Institute?

Chuck: My predecessor as chief executive officer of Union Electric was chairman of the St. Louis Children’s Hospital board. He got me involved. I’ve been on the hospital board for about 20 years. I was chairman for six years. I’ve been on the Foundation board for eight or 10 years, and I’ve been on the Children’s Discovery Institute board since its inception. I was co-chairman of the capital campaign that raised money for the Children’s Discovery Institute. I got interested in it when I heard it described and its goals of accelerating cures for kids, alleviating kids’ suffering and preventing diseases. It’s pretty easy to buy into.

Q: Why are you enthusiastic about supporting the Children’s Discovery Institute?

Chuck: First of all, I know St. Louis Children’s Hospital very well. Their motto is “do what’s right for kids,” and I’ve seen it in the hospital staff and administration. It’s a very efficient, competent and caring organization, and really the sponsor of the Children’s Discovery Institute. St. Louis Children’s Hospital has teamed up with Washington University, which is a top-notch research organization in the country. You just couldn’t duplicate that. It’s like a marriage made in heaven, and it’s pretty easy to get enthused about it.

Q: What makes the Children’s Discovery Institute unique among charitable organizations?

Chuck: It’s a research organization focused on pediatrics, which is very short of funding. The process at the Children’s Discovery Institute is very efficient. A scientific panel selects worthwhile causes. That panel stresses the work of young researchers. It’s seed money to get these young people started in research doing pediatric work and to set them up for grants from the National Institutes of Health. It’s a team-based approach. It’s not just the medical school at Washington University that’s involved. There are no silos. The Institute brings in the physics and chemistry departments and everyone else. Oversight

is provided by board representatives at St. Louis Children’s Hospital and Washington University. I think it’s a very worthwhile endeavor.

Q: Why do you consider the Children’s Discovery Institute a good investment?

Chuck: The Children’s Discovery Institute is a good bang for your buck. We’ve seen some results already, and since we’re dealing with kids, they have a long life ahead of them, so the payback is long-term.

Chuck graduated from Saint Louis University with a bachelor’s degree in electrical engineering and an MBA. He started working for Union Electric Company (now Ameren) in 1961 and became the company’s chief executive officer in 1993. Retired for 10 years, he currently serves on the boards of St. Louis Children’s Hospital and the Municipal Theatre Association of St. Louis. His wife, Jan, was a legal assistant who later stayed at home to raise their three sons. Chuck and

Jan also have eight grandchildren and one great-grandson. ›
