NORC, the only one in Texas, to investigate causes, prevention, and treatment options for $175 billion obesity epidemic

DALLAS – Sept. 21, 2022 – UT Southwestern Medical Center has been selected to be one of 12 NIH Nutrition Obesity Research Centers in the nation – and the only one in Texas – to investigate the causes, prevention, and treatment options for obesity, a chronic disease affecting more than 40% of the U.S. population with medical costs nearing $175 billion.

More than 150 UT Southwestern scientists across dozens of departments in fields ranging from metabolism to genetics will be part of the elite National Institutes of Health-funded, university-wide interdisciplinary research center. UT Southwestern will receive $6.15 million in grant funding over five years from the National Institute of Diabetes and Digestive and Kidney Diseases. Among the center's faculty are three Nobel Laureates, 11 members of the National Academy of Sciences, seven members of the National Academy of Medicine, and seven Howard Hughes Medical Institute Investigators.

"The UT Southwestern Nutrition Obesity Research Center provides an important mechanism to accelerate translation of basic scientific discoveries into clinically relevant interventions to improve public health," said Jay Horton, M.D., Director of the Center for Human Nutrition at UT Southwestern and Director of the new Nutrition Obesity Research Center.

Over the last 20 years, the prevalence of U.S. obesity has risen steadily from 30% to 42%, with the prevalence of severe obesity nearly doubling to 9.2%, according to the National Health and Nutrition Examination Survey from the Centers for Disease Control and Prevention. Obesity takes a greater toll on people of color – reported in nearly 50% of non-Hispanic Black adults, more than 45% of Hispanic adults, 41% of non-Hispanic white adults, and 16% of non-Hispanic Asian adults. Medical costs for obese adults are more than $1,800 higher than for those with healthy weight.

Obesity-related conditions include heart disease, stroke, Type 2 diabetes, nonalcoholic fatty liver disease, and several types of cancer, all among the leading causes of preventable, premature death, according to the CDC.

"Ultimately, our goal is to enhance the innovative nutrition and obesity research these investigators are currently engaged in and facilitate the translation of basic scientific discoveries into new therapeutic strategies for the prevention and treatment of obesity and the metabolic syndrome," said Philipp Scherer, Ph.D., Professor of Internal Medicine and Cell Biology at UT Southwestern, Director of the Touchstone Diabetes Center, and Associate Director of the Nutrition Obesity Research Center.

The Obesity Center's research base consists of 158 investigators from 27 different departments, along with members of UT Southwestern's Peter O’Donnell Jr. Brain Institute, Harold C. Simmons Comprehensive Cancer Center, Center for Human Nutrition, Peter O’Donnell Jr. School of Public Health, and UT Southwestern School of Health Professions. Collectively, these researchers have 230 nutrition and obesity-related research grants and research support totaling more than $74 million a year, including funding from the NIH, Department of Defense, Howard Hughes Medical Institute, American Diabetes Association, National Cancer Institute, and the Cancer Prevention and Research Institute of Texas.

UT Southwestern has continued to strengthen its expertise in the field with assistance from the state of Texas, which provided $8 million per year for obesity-related research to UT Southwestern in 2009-11 and $6.5 million in subsequent years (2011-19) that not only helped demonstrate the commitment of UT Southwestern and the state of Texas to addressing the epidemic, but also facilitated the development of the current diverse and accomplished group of investigators that comprise the new center.

"We have assembled a highly interactive and collaborative interdisciplinary team of investigators with a goal of defining the behavioral, metabolic, genetic, and molecular mechanisms contributing to obesity and obesity-induced disease," said Dr. Horton, Professor of Internal Medicine in the Division of Digestive and Liver Diseases, with a secondary appointment in Molecular Genetics.

To facilitate interdisciplinary research and the exchange of ideas, the UTSW Nutrition Obesity Research Center has created four thematically related teams:

"Within each team, we have integrated basic and translational scientists from a wide spectrum of disciplines to comprehensively address the biochemical, metabolic, and clinical consequences of obesity and obesity-related diseases," said Dr. Horton.

A Pilot and Feasibility program, directed by Joel Elmquist, D.V.M., Ph.D., and Associate Director of the Nutrition Obesity Research Center, and Joyce Repa, Ph.D., Associate Professor of Physiology and Internal Medicine, will support early-stage projects of four new investigators per year. An Enrichment Program, led by Jeffrey Zigman, M.D., Ph.D., Professor of Internal Medicine and a Principal Investigator in the Center for Hypothalamic Research, will provide enhanced educational opportunities for graduate students, postdoctoral fellows, and faculty interested in performing basic science and translational research related to nutrition, obesity, and obesity-related diseases.

Four cores and a clinical element also have been established to provide state-of-the art services: Animal Phenotyping/Metabolism Core; Lipid Mass Spectrometry Core; Quantitative Metabolism and Imaging Core; and Genetics, Single Cell Sequencing, and RNA Sequencing Core.

Dr. Elmquist holds the Maclin Family Distinguished Professorship in Medical Science, in Honor of Dr. Roy A. Brinkley, and the Carl H. Westcott Distinguished Chair in Medical Research.

Dr. Horton holds the Center for Human Nutrition Director's Endowed Chair, the Scott Grundy Director's Chair, The Dr. Robert C. and Veronica Atkins Chair in Obesity & Diabetes Research, and the Distinguished University Chair in Human Nutrition.

Dr. Scherer holds the Gifford O. Touchstone, Jr. and Randolph G. Touchstone Distinguished Chair in Diabetes Research and the Touchstone/West Distinguished Chair in Diabetes Research.

Dr. Zigman holds the Kent and Jodi Foster Distinguished Chair in Endocrinology, in Honor of Daniel Foster, M.D., The Diana and Richard C. Strauss Professorship in Biomedical Research, and the Mr. and Mrs. Bruce G. Brookshire Professorship in Medicine.
