Glut4 Is Reduced In Slow Muscle Fibers Of Type 2 Diabetes Muscle Groupspecific Regulation Of Glut 4 Glucose The impact of diabetes and insulin therapy on glut 4 expression also varied as a function of muscle group. after four weeks of diabetes, glut 4 levels were reduced by approximately 50% in cardiac muscle, soleus, and gastrocnemius. in contrast, glut 4 content in rectus abdominis and vastus lateralis was similar to that in control rats. Exercise, glut4, and skeletal muscle glucose uptake glucose is an important fuel for contracting muscle, and normal glucose metabolism is vital for health. glucose enters the muscle cell via facilitated diffusion through the glut4 glucose transporter which translocates from intracellular storage depots to the plasma m. Total glut4 content in skeletal muscle from individuals with type 2 diabetes is normal; however, recent studies have demonstrated that translocation of glut4 to the plasma membrane is decreased in and diabetes glut4 response to i...

The primary regulatory mechanism by which glucose uptake takes place is via insulin-stimulated transport of glucose into skeletal muscle and adipose tissue, primarily mediated by glucose transporter protein type-4 (glut4). glut4 is a key component in glucose homeostasis and the removal of glucose from circulation. The mechanism for glut4 is an example of a cascade effect, where binding of a ligand to a membrane receptor amplifies the signal and causes a cellular response. in this case, insulin binds to the insulin receptor in its dimeric form and activates the receptor's tyrosine-kinase domain. the receptor then recruits insulin receptor substrate, or irs-1, which binds the enzyme pi-3 kinase. In contrast, in type 2 diabetic subjects, glut4 density was significantly lower in slow compared with fast fibers. glut4 density in slow fibers from diabetic patients was reduced by 9% compared with the weight-matched obese subjects and by 18% compared with the lean control group. Glut4 conte...
