In skeletal muscle, the reduced GLUT4 expression in severe insulin resistance was associated with decreased ubiquitin-conjugating enzyme 9 (UBC9) expression while expression of GLUT1, TBC1D1 and AS160 was not significantly different among type 2 diabetic patients and matched controls.

In L6 muscle cells in culture, acute treatment (1 h) with insulin causes recruitment of glucose transporters to the plasma membrane, and prolonged exposure to insulin or to glucose-deprived medium causes increased expression of GLUT-1 mRNA and GLUT-1 protein.

A major portion of insulin-mediated glucose uptake occurs via the translocation of GLUT 4 glucose transporter proteins from an intracellular depot to the plasma membrane.

We have examined gene expression for the GLUT 4 transporter isoform in subcutaneous adipocytes, a classic insulin target cell, to better understand molecular mechanisms causing insulin resistance in non-insulin-dependent diabetes mellitus (NIDDM) and obesity.
|

|
In obesity, cellular depletion of GLUT 4 primarily involved low density microsomes (LDM), leaving fewer transporters available for insulin-mediated recruitment to the plasma membrane (PM).
|

|
We conclude that, in obesity, insulin resistance in adipocytes is due to depletion of GLUT 4 glucose transporters, and that the cellular content of GLUT 4 is determined by the level of encoding mRNA over a wide range of body weight.

|
Thus, pretranslational suppression of GLUT 4 transporter gene expression may be an important mechanism that produces and maintains cellular insulin resistance in NIDDM.

Induction of diabetes with streptozocin decreased the GLUT4 to GLUT1 ratio in adipose tissue 4-fold and 24 h of insulin treatment of the diabetic rats increased this ratio 9- to 10-fold.

By immunofluorescence and Western blotting we studied whether glucose or insulin is the primary extracellular signal for inducing GLUT-1 expression in hepatocytes.

|
Chronic insulin treatment of diabetic rats reduces the number of rows of hepatocytes expressing GLUT-1 from approximately four to approximately two.
|

|
In contrast, chronic insulin infusion into nondiabetic rats does not affect the number of hepatocytes expressing GLUT-1.

Insulin acutely increases glucose transport in muscle by selectively stimulating the recruitment of the GLUT4 transporter (but not GLUT1) from an intracellular pool to the plasma membrane.

GLUT 2 is necessary to reconstitute glucose-sensitive insulin secretion in pituitary tumour cells expressing a proinsulin cDNA.

|
The predominant mechanism by which insulin activates glucose transport in muscle and adipose tissue is by affecting the redistribution of the facilitated hexose carriers, GLUT1 and GLUT4, from an intracellular site to the plasma membrane.

After an acute treatment with insulin, the proportions of GLUT4 and GLUT1 at the cell surface were increased to 49 and 37% of the total, respectively.

In HIR-cells, which express GLUT1 and not GLUT4, basal and insulin-stimulated glucose transport were unaffected by glucosamine, but glycogen synthesis was markedly inhibited.

The EC50 for glucose transport was similar in endothelial cells and pericytes (3.94 to 0.48 mM versus 2.24 to 0.69 mM) and was consistent with the EC50 previously reported for GLUT1 transporters on other cells, as was the observation that insulin did not acutely stimulate glucose transport in either cell type.

We investigated whether a defect of insulin-dependent glucose transporter (GLUT 4) translocation might contribute to the pathogenesis of the insulin-resistant state. fa/fa rats, lean controls (Fa/Fa) as well as normal Wistar rats were injected intraperitoneally with insulin and were killed after 2 or 20 min, respectively.

Insulin induced an approximately two-fold increase of GLUT 4 in a plasma membrane and transverse tubule enriched fraction and a decrease in the low density enriched membrane fraction in all three groups of rats.

The data suggest that skeletal muscle insulin resistance of obese Zucker rats is not associated with a lack of GLUT 4 translocation.

|
The recent finding that GLUT 4 is also expressed in the hypothalamus suggests that this brain region, which is outside the blood-brain barrier and therefore sensitive to circulating insulin, may experience stimulation of glucose uptake in response to insulin.

The effects of insulin and IGF-I on the cell surface quantities of GLUT1, GLUT3 and GLUT4 glucose transporters in L6 myotubes were determined with the exofacial bis-mannose phololabel (ATB-BMPA).

MKP-4 also reversed the effect of TNF-alpha to inhibit insulin signaling; alter IL-6, Glut1 and Glut4 expression; and inhibit insulin-stimulated glucose uptake in 3T3-L1 adipocytes.

Influence of insulin (0.02 micromol/L) on isometric twitch force was examined with and without blocking glucose transporter (GLUT) 4 translocation (latrunculin), sodium-coupled glucose transporter (SGLT) 1 (phlorizin, T-1095A), or PI3-kinase (wortmannin).

As abnormal cellular glucose uptake and metabolism are partly involved in diabetic complications, this study was undertaken to explore the effect of hyperglycemia on glucose uptake, glucose transporter1 (GLUT1) expression induced by insulin of rat mandibular osteoblasts.

The results showed that with 16.5mmol/L glucose, glucose uptake was not changed significantly, but GLUT1 expression was increased by 35% (P<0.01), insulin had no significant effect on glucose uptake, but it decreased GLUT1 expression by 33% (P<0.01).

It is concluded that hyperglycemia can induce insulin resistance of osteoblasts, in which alteration in transport activity and function of GLUT1 might be involved.
