The Role of Protein Phosphatase-1 in Insulin Action

WebHere, we examine the hypothesis that insulin-stimulated phosphate transport may be a key mediator in the ability of insulin to augment ATP synthesis in skeletal muscle. In order to … The functioning of a signal transduction pathway is based on extra-cellular signaling that in turn creates a response that causes other subsequent responses, hence creating a chain reaction, or cascade. During the course of signaling, the cell uses each response for accomplishing some kind of a purpose along the way. Insulin secretion mechanism is a common example of signal transduction pathway mechanism. images of purses with handkerchief

Regulation of the Na+/K+-ATPase by insulin: why and how?

WebOct 8, 2009 · The lack of intracellular phosphate complementary to the increased intracellular glucose takes place in the insulin-insensitive cells and tissues, resulting in the possibility of DLC. Many of the obvious dietary and pharmacological routes explored thus far to overcome this problem are evaluated herein. WebOct 9, 1998 · Glucose transport into muscle cell is mediated by two glucose transport proteins: insulin-independent GLUT1 and insulin-dependent GLUT4. If glucose is transported though the GLUT1 pathway, it is further metabolized by hexokinase I via glucose 6-phosphate (G-6-P) and fructose 6-phosphate (F-6-P) also to hexosamines.
