Glucosamine 17-28 insulin Homo sapiens 70-77 20165829-2 2010 Here we sought to evaluate the possible role of endoplasmic reticulum (ER) stress in the induction of insulin resistance by glucosamine in skeletal muscle cells. Glucosamine 124-135 insulin Homo sapiens 102-109 20165829-5 2010 In addition, glucosamine impaired insulin-stimulated 2-DG uptake in both rat and human myotubes. Glucosamine 13-24 insulin Homo sapiens 34-41 20165829-6 2010 Interestingly, pretreatment of both rat and human myotubes with the chemical chaperones 4-phenylbutyric acid (PBA) or tauroursodeoxycholic acid (TUDCA), completely prevented the effect of glucosamine on both ER stress induction and insulin-induced glucose uptake. Glucosamine 188-199 insulin Homo sapiens 232-239 20165829-10 2010 CONCLUSIONS/INTERPRETATION: In this work we show that glucosamine-induced ER stress causes insulin resistance in both human and rat myotubes and impairs GLUT4 production and insulin-induced glucose uptake via an ATF6-dependent decrease of the GLUT4 regulators MEF2A and PGC1alpha. Glucosamine 54-65 insulin Homo sapiens 91-98 20165829-10 2010 CONCLUSIONS/INTERPRETATION: In this work we show that glucosamine-induced ER stress causes insulin resistance in both human and rat myotubes and impairs GLUT4 production and insulin-induced glucose uptake via an ATF6-dependent decrease of the GLUT4 regulators MEF2A and PGC1alpha.
