Protein Key To New Therapies For People With Elevated Triglycerides
Diabetes researchers at the John G. Rangos Sr. Research Center at Children's Hospital of Pittsburgh of UPMC have identified a potential target for the development of new therapies to treat hypertriglyceridemia, a lipid disorder commonly seen in people who are obese and diabetic. Results of their study are published in the June issue of the Journal of Clinical Investigation.
Scientists in the Division of Immunogenetics at Children's Hospital studied the role of a protein known as Forkhead Box O1 (FoxO1) that mediates the metabolism of glucose and cholesterol. In the laboratory, the researchers were able to curb the secretion of triglycerides in animals that were obese and diabetic by inhibiting the production of FoxO1 in the liver. Elevated triglyceride levels have been identified as a risk factor for heart disease.
