cómo se transporta la glucosa través de la membrana celular? diana díaz hernández, luis carlos burgos herrera de la célula para su ingreso requiere una. RESUMEN El transporte de la glucosa a través de la membrana plasmática de a sodio (SGLT) y los sistemas facilitadores del transporte de glucosa (GLUT). Se han descrito dos sistemas de transporte de glucosa y de otros monosacáridos : y los transportadores de glucosa llamados GLUT (glucosa transporters).

Each glucose transporter isoform plays a specific role in glucose metabolism determined by its pattern of tissue expression, substrate specificity, transport kinetics, and regulated expression in different physiological conditions. Abundant during stationary phase, sporulation and hluts glucose conditions. Differential regulation of adipose tissues glucose transporters in genetic obesity fatty rat.

GLUT is a type of uniporter transporter protein. The effect of adipose cell size on the measurement of GLUT 4 in white adipose tissue of obese mice.

Comparison of kinetic parameters. Is a high-affinity isoform, allowing it to transport even in times of low glucose concentrations. Decreased expression of glucose transporter in muscle from insulin-resistant patients. J Cell Biol ; Am J Nephrol ;4: Annu Rev Biochem ; Quantification of GLUT4 transporter in insulin-sensitive tissues from pinealectomized rats. GLUT1 expression is upregulated in many tumors. Reduced content and preserved translocation of glucose transporter GLUT 4 in white adipose tissue of obese mice.

Tese – Mestrado -Escola Paulista de Medicina. It is also present in the basolateral membrane of the small intestine epithelium. Regulation of expression of glucose transporters by glucose: Defective glucose transport across the blood-brain barrier as a cause of persistent gucosa, seizures, and developmental delay. J Bacteriol ; Decreased glucose transporter GLUT 4 content in insulin-sensitive tissues of obese aurothioglucose- and monosodium glutamate-treated mice.

Transportador de glucosa

Sequence and structure of a human glucose transporter. Physiol Rev ; The inner and outer glucose-binding sites are, it seems, located in transmembrane segments 9, 10, 11; [8] also, glyts DLS motif located in the seventh transmembrane segment could be involved in the selection and affinity of transported substrate. Close genetic linkage between HLA and renal glycosuria.

Is expressed by renal tubular cells, liver cells and pancreatic beta cells. All three monosaccharides glucosegalactoseand fructose are transported from the intestinal mucosal cell into the portal circulation by GLUT2.

Immuno-localization of the insulin regulatable glucose transporter in brown adipose tissue of the rat.

Whether mechanisms exist to promote cell-surface translocation of these transporters is not yet known, but it has clearly been established that insulin does not promote GLUT6 and GLUT8 cell-surface translocation. 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.

Structure and function of mammalian facultative sugar transporters. J Biol Chem ; Glts a high-frequency and low-affinity isoform.

GLUTs are integral membrane proteins that contain 12 membrane-spanning helices with both the amino and carboxyl termini exposed on the cytoplasmic side of the plasma membrane.
