Bidirectionality is required in liver cells to uptake glucose for glycolysis and glygogenesis, and release of glucose during gluconeogenesis. From Wikipedia, the free encyclopedia. These studies have revealed that, in DM2, the GLUT4 content is drastically reduced, playing an important role in insulin resistance.

GLUT1 transpirtadores is upregulated in many tumors. Is the insulin -regulated glucose transporter. Differential regulation of adipose tissues glucose transporters in genetic obesity fatty rat. Responsible for insulin-regulated glucose storage.

It is plausible to propose that the modulation of GLUT4 is triggered by a combination of factors indicating cellular sensitiveness to insulin.

Regulation of expression of glucose transporters by glucose: In familial renal glycosuria, the participation of SGLT2 and SGLT1 seems to be fundamental, either by loss of transport capacity or by decrease in the transporter affinity.

Nature Lond ; Retrieved from ” https: Effect of the thermogenic agent BRL A. In Saccharomyces cerevisiae glucose transport takes place through facilitated diffusion.

J Clin Invest ; N Engl J Med ; Is expressed by renal tubular cells, liver cells and pancreatic beta cells. Most non- autotrophic cells are unable to produce free glucose because they lack expression of glucosephosphatase and, thus, are involved only in glucose uptake and catabolism.

Usually produced only in hepatocytesin fasting conditions, other tissues such as the intestines, muscles, brain, and kidneys are able to produce glucose following activation of gluconeogenesis. Machado UF, Saito M.
