San Antonio, Texas (Nov. 15, 2017) – Texas Biomedical Research Institute scientists have been granted funding from the National Institutes of Health to pursue a promising study on the ultimate causes of heart disease and metabolic disorders. Principal Investigators Raul A. Bastarrachea, MD, and Jack W. Kent Jr., Ph.D., of Texas Biomedical Research Institute have designed the GEMM Family Study (Genetics of Metabolic Diseases in Mexico).
The GEMM Family Study examines volunteers from 10 university hospital sites in Mexico. Blood samples and tissue samples collected from participants are analyzed at Texas Biomedical Research Institute in San Antonio, Texas.
Healthy adults provide baseline blood samples and muscle biopsies at fasting. Then, they are given what's called a meal challenge. The volunteers eat 30 percent of what their bodies need for their individual daily energy needs based on their Base Metabolic Rate (BMR) and activity level.
If their metabolism is working correctly, that food – a balanced mix of proteins, carbohydrates, fat and micronutrients – should be metabolized, oxidized, or stored within five hours. By taking another muscle biopsy and blood samples at several points during the five hours following the meal, the researchers hope to find out why some otherwise healthy people may have an impaired response to a meal which can lead to cardiovascular disease over time.
"The idea behind the GEMM Family Study is to pinpoint novel biomarkers of metabolic responses that could be early predictors of cardiovascular disease," explained Dr. Bastarrachea. Distinguishing those biomarkers could lead to earlier diagnoses and interventions based on individual results.
Heart disease is a major health problem for Hispanic Americans. High rates of obesity, diabetes and high blood pressure put them at great risk for cardiovascular problems like strokes and heart attacks. The scientists anticipate that findings from the GEMM Family Study will have implications for diagnosing and treating cardiovascular disease on both sides of the U.S.-Mexico border.
The National Institute of Diabetes and Digestive and Kidney Diseases, part of the National Institutes of Health, has awarded the GEMM Family Study researchers $544,803 over two years to study data from 40 people in Mexico. Using that preliminary data, Texas Biomed scientists plan to apply for a larger NIH grant that would fund the study of data collected from 400 individuals.
"I take this grant as a strong vote of confidence," Dr. Kent said. "They (the NIH) liked the study design."
Texas Biomed has a long history of researching genetic contributors to heart disease risk in family studies, including ongoing collaboration in the StrongHeart Study of American Indians.
