A combination of CLA-DAG oil modifies the diabetic phenotype in male Zucker diabetic fatty rats.
Horm Metab Res. 2008 Apr; 40(4):262-8.HM

Abstract

A number of human and animal studies using conjugated linoleic acids (CLA) or diacylglycerol (DAG) oil have shown positive physiological effects on abdominal adiposity, plasma triglycerides, plasma glucose, and insulin sensitivity. A novel DAG composition containing CLA called CLA diacylglyceride (CLA-DAG) may offer potential as a therapeutic agent in reducing some of the symptoms associated with the diabetic phenotype and metabolic syndrome. This study was designed to investigate the effect of CLA-DAG oil on the diabetic phenotype in male Zucker diabetic fatty rats. Animals were assigned to one of four groups: control (C), rosiglitazone (ROS), CLA-DAG, or CLA as free fatty acid (CLA-FFA). After 11 weeks, body weight was higher and kidney weight was lower in the CLA-DAG and ROS groups compared with the C group. The ROS treatment increased the percentage of body fat as compared with all other groups. Final fasting blood glucose was lower in the CLA-DAG and ROS groups than in the C group. Plasma cholesterol was lower in the CLA-DAG group, and plasma triglycerides were lower in the ROS group compared with the C group. We also observed changes in transcript abundance of PPAR-gamma, PPAR-alpha, FAS, LPL, UCP2, UCP3, CPT1, RxR, ObRb, ApoAII, ApoD, and IRS1 in liver, muscle, and adipose tissue, suggesting treatment-induced effects on these genes. Collectively, these data suggest the need for further research on the therapeutic relevance of CLA-DAG oil in obesity and diabetes. Future research should also differentiate between CLA alone and DAG alone compared with the combination.
