Effects of resistin on skeletal glucose metabolism.
Front Med China. 2010 Sep; 4(3):329-35.FM

Abstract

Resistin is an adipokine highly related to insulin resistance (IR). The purpose of our research was to investigate how resistin influences skeletal glucose metabolism and explore its mechanisms. We constructed the recombinant plasmid pcDNA3.1 expressing resistin and then transfected it into C2C12 myocytes. The expression of resistin in C2C12 myocytes was detected by Western blotting. Glucose uptake was measured by 3H labeled glucose; glucose oxidation and glycogen synthesis was detected with 14C-labeled glucose. GLUT4 mRNA was measured by reverse transcription polymerase chain reaction (RT-PCR). We observed that resistin was expressed in transfected myocytes, and resistin decreased insulin induced glucose uptake rate by 28%-31% and inhibited the expression of GLUT4 mRNA. However, there was no significant difference in basal glucose uptake, and glucose oxidation and glycogen synthesis remained unchanged in all groups. It is concluded that resistin inhibits insulin induced glucose uptake in myocytes by downregulating the expression of GLUT4 and it has no effects on glucose oxidation and glycogen synthesis. Our findings may provide a clue to understand the roles of resistin in the pathogenesis of skeletal IR.
