Abstract:Although insulin resistance in peripheral tissue has been demonstrated in patients with cardiac disease, expression of glucose transporter (GLUT) isoform mRNA in the cardiac muscle is not known. We analyzed GLUT isoform mRNA in the cardiac muscle of 10 patients by RT-PCR. GLUT 4 mRNA was semi-quantitated by kinetic analysis, altering the cycles of PCR, and insulin resistance was examined by euglycemic hyperinsulinemic glucose clamp with an artificial pancreas. In addition to GLUT 2, 3, and 4 mRNA, all of which… Show more
