Now, researchers at Cedars-Sinai Medical Center, in collaboration with investigators at UCLA, have found that lipoprotein lipase (LPL), a gene that controls the delivery of fatty acids to muscle and tissues in the body, is linked to insulin resistance in Mexican-Americans. Their findings, reported in the January issue of Diabetes, may enable scientists to design therapies that target LPL to prevent insulin resistance, a condition estimated to affect over 80 percent of the 16 million Americans with Type 2 diabetes, and additional millions at risk for heart disease.
"This is the first study to definitively show that LPL is a gene for common insulin resistance," said Jerome I. Rotter, M.D., Director of the Division of Medical Genetics and Director of the Common Disease Genetics Program at Cedars-Sinai Medical Center.
In recent years, LPL has emerged as a likely "gene candidate" to study for insulin resistance because some studies had linked it to high blood pressure, obesity, and atherosclerosis (fatty deposits in the arteries) all of which are associated with the insulin resistance syndrome. But the studies were small, used limited diagnostic tests, and looked at only small portions of the LPL gene.
To determine whether LPL was directly linked to insulin resistance, researchers under Dr. Rotter's direc
