Regulated membrane trafficking of the insulin-responsive glucose transporter 4 in adipocytes.
Since the discovery of insulin roughly 80 yr ago, much has been learned about how target cells receive, interpret, and respond to this peptide hormone. For example, we now know that insulin activates the tyrosine kinase activity of its cell surface receptor, thereby triggering intracellular signaling cascades that regulate many cellular processes. With respect to glucose homeostasis, these incl...
متن کاملThe comparison of continuous and intermittent training impact on glucose-4 transporter protein level and insulin sensitivity in diabetic rats
Introduction: Diabetes mellitus (DM) is now seen as a worldwide epidemic disease with high prevalence. Exercise training (ET) is known to promote beneficial changes in diabetic patients. The aim of this study was to compare the impact of continuous and intermittent aerobic training on glucose-4 transporter protein (GLUT-4) levels and insulin sensitivity in diabetic rats. Materials and meth...
متن کاملTargeting of the insulin-regulatable glucose transporter (GLUT-4).
668 A family of facilitative glucose transporters (GLUTS 1-7) has recently been identified in mammals [ 11. It is of key interest to determine the unique function of each GLUT isoform in an effort to broaden our understanding of whole body glucose homeostasis. An isoform of relevance to the regulation of glucose metabolism by insulin is GLUT-4. The expression of this isoform is confined to tiss...
متن کاملRole of insulin-dependent cortical fodrin/spectrin remodeling in glucose transporter 4 translocation in rat adipocytes.
Fodrin or nonerythroid spectrin is an abundant component of the cortical cytoskeletal network in rat adipocytes. Fodrin has a highly punctate distribution in resting cells, and insulin causes a dramatic remodeling of fodrin to a more diffuse pattern. Insulin-mediated remodeling of actin occurs to a lesser extent than does that of fodrin. We show that fodrin interacts with the t-soluble N-ethylm...
متن کاملEndocytosis, recycling, and regulated exocytosis of glucose transporter 4.
Glucose transporter 4 (GLUT4) is responsible for the uptake of glucose into muscle and adipose tissues. Under resting conditions, GLUT4 is dynamically retained through idle cycling among selective intracellular compartments, from whence it undergoes slow recycling to the plasma membrane (PM). This dynamic retention can be released by command from intracellular signals elicited by insulin and ot...
