​Taskforce for Obesity Research at Southwestern (TORS)

The Interdisciplinary Research program has transitioned from Common Fund support. For more information, please visit http://commonfund.nih.gov/Interdisciplinary. Consortium activities may continue to be supported via other sources.

 

 

 

Executive Summary

Obesity and its associated diseases (heart disease, diabetes, high blood pressure, and fatty liver disease) contribute importantly to death and disability in the United States. To develop a comprehensive understanding of the factors that lead to obesity and its complications, we assembled a collaborative interdisciplinary team of experts at UT Southwestern called the Taskforce for Obesity Research at Southwestern (TORS). TORS harnessed expertise from more than 30 investigators from 20 highly diverse disciplines with a goal of defining the behavioral, metabolic, genetic, and cellular mechanisms that lead to the development of obesity and associated diseases. Our studies provided much needed insights into the key molecules and pathways that regulate energy metabolism, which will be translated into the development of new approaches to prevent obesity and to treat the metabolic complications of this disorder.
