The future of children's health

Can diseases such as Alzheimers, obesity and diabetes be prevented before birth? As per Jonathan D. Gitlin, M.D., the Helene B. Roberson Professor of Pediatrics and Professor of Genetics at the Washington University School of Medicine, researching whether diseases that strike adults are already genetically encoded in individuals while still in the womb, may enable physicians to one day address and prevent diseases in infancy.

In a talk entitled Child Health Research in the 21st Century: Obstacles and Opportunities, Dr. Gitlin, who is also scientific director of the Childrens Discovery Institute, will address why, despite substantial investments in both the academic and private sectors, the health status of our nation remains dismal especially the health and wellness of our children.

Childrens health has been pushed aside, states Dr. Gitlin. The amount of money currently dedicated to research that could identify key factors leading to diseases both in childhood and later in their adult lives is very small in comparison to the funding for adult onset diseases such as heart disease or cancer. Dr. Gitlin says researchers need to redirect their thinking to find a way to identify and ultimately offset diseases in children that may affect them during the later part of life, such as obesity, depression or even drug and alcohol addiction.

Dr. Gitlin will also discuss how the identification of human genome sequencing now offers scientists the opportunity to change not only the direction of science, but also of medical care, by looking into more ways to prevent diseases from conception while understanding each persons individual genetic make up. There is also tremendous potential for drug discovery and small molecule alteration for long-term intervention and prevention of diseases that could be genetically imprinted in individuals before birth.

Going into the 21st Century, we have the capacity to eliminate a number of childhood diseases. We can now know the fetal origins of a number of adult diseases, such as diabetes and obesity, and how lifestyles -- in terms of food intake and environmental factors, may contribute or help prevent certain diseases, explains Dr. Gitlin.

Dr. Gitlin uses zebra fish to illustrate this theory with a chemical genetic screen to identify small molecules and note their influence on nutrient metabolism. When we think about controlling our environment, the one thing we can control is nutrition. So the question we are trying to answer is Can we take a simple, genetically tractable organism thats similar in development to humans and manipulate the nutrition and understand by that manipulation what kind of metabolic outcome we get? Findings from this research may ultimately reveal the genetic factors that suggest how nutrients are metabolized and how this may contribute to birth defects and long-term metabolic abnormalities.
