Interplay between FGF21 and insulin action in the liver regulates metabolism Emanuelli B; Vienberg SG; Smyth G; Cheng C; Stanford KI; Arumugam M; Michael MD; Adams AC; Kharitonenkov A; Kahn CRJ Clin Invest 2014[Feb]; 124 (2): 515-27The hormone FGF21 regulates carbohydrate and lipid homeostasis as well as body weight, and increasing FGF21 improves metabolic abnormalities associated with obesity and diabetes. FGF21 is thought to act on its target tissues, including liver and adipose tissue, to improve insulin sensitivity and reduce adiposity. Here, we used mice with selective hepatic inactivation of the IR (LIRKO) to determine whether insulin sensitization in liver mediates FGF21 metabolic actions. Remarkably, hyperglycemia was completely normalized following FGF21 treatment in LIRKO mice, even though FGF21 did not reduce gluconeogenesis in these animals. Improvements in blood sugar were due in part to increased glucose uptake in brown fat, browning of white fat, and overall increased energy expenditure. These effects were preserved even after removal of the main interscapular brown fat pad. In contrast to its retained effects on reducing glucose levels, the effects of FGF21 on reducing circulating cholesterol and hepatic triglycerides and regulating the expression of key genes involved in cholesterol and lipid metabolism in liver were disrupted in LIRKO mice. Thus, FGF21 corrects hyperglycemia in diabetic mice independently of insulin action in the liver by increasing energy metabolism via activation of brown fat and browning of white fat, but intact liver insulin action is required for FGF21 to control hepatic lipid metabolism.|*Gene Expression Regulation[MESH]|Adipose Tissue/metabolism[MESH]|Animals[MESH]|Blood Glucose/metabolism[MESH]|Body Weight[MESH]|Cholesterol/metabolism[MESH]|Fibroblast Growth Factors/*metabolism[MESH]|Hyperglycemia/metabolism[MESH]|Insulin Resistance/genetics[MESH]|Insulin/*metabolism[MESH]|Lipids/chemistry[MESH]|Liver/*metabolism[MESH]|Male[MESH]|Mice[MESH]|Mice, Knockout[MESH]|Organ Size[MESH]|Time Factors[MESH] |
