Colocalization of GLUT2 glucose transporter, sodium/glucose cotransporter, and gamma-glutamyl transpeptidase in rat kidney with double-peroxidase immunocytochemistry.
|
2 |
1350259
|
Genes for both a renal Na(+)-glucose cotransporter (SGLT1) and a renal facilitated glucose transporter (GLUT2) have been cloned and sequenced.
|
3 |
1350259
|
To examine whether SGLT1 and GLUT2 colocalize to the same tubular epithelial cells in rat kidney, double-immunoperoxidase studies with dual chromogens and paraformaldehyde perfusion-fixed frozen sections of rat kidney were performed.
|
4 |
1350259
|
Antipeptide antisera were prepared against rat GLUT2 (amino acids 510-522) and rabbit SGLT1 (amino acids 402-420).
|
5 |
1350259
|
GLUT2 and SGLT1 colocalized to 40% of cortical epithelium, but 16% of cortical epithelial cells were immunopositive for brush border SGLT1 and immunonegative for basolateral GLUT2.
|
6 |
1350259
|
These gamma-glutamyl transpeptidase staining results suggest that at least 50% of the tubules in the cortex are proximal tubules and that SGLT1 and GLUT2 colocalize to most proximal tubules.
|
7 |
1350259
|
The fact that SGLT1 antiserum immunoreacted with tubules unreactive to the GLUT2 antiserum suggests that either the SGLT1 epitope is conserved on a related brush border protein or that there is another GLUT transporter responsible for the exit of sugar from these proximal tubule cells.

|
For example, alterations in the synthesis of glucose carriers and their subsequent insertion into membranes may alter sugar entry across the intestinal brush border membrane (BBM) using the sodium-dependent D-glucose transporter, SGLT1, or the BBM sodium-independent facultative fructose transporter, GLUT5, and may alter facilitated sugar exit across the basolateral membrane (BLM) using GLUT2.
|

|
On the BBM the sodium (Na)/glucose transporters (SGLT1 and SGLT2), the Na-independent transporter (GLUT5), and on the BLM the hexose transporter (GLUT2) are discussed.

|
Glucose transporters, or membrane proteins, which incorporate glucose into the cell, can be divided into two groups: the facilitative type glucose transporter (GLUT), and the sodium/glucose cotransporter (SGLT).
|
23 |
15544472
|
Among the GLUT family isoforms, GLUT4 is particularly important for maintaining glucose metabolism homeostasis since it is involved in insulin or exercise-induced glucose transport into muscle and adipose tissues via movement from intracellular sites to the plasma membrane in response to stimulation.
|
24 |
15544472
|
Thus, agents which induce GLUT4 translocation or improve insulin sensitivity, involved in this insulin-induced step, hold the promise of being potent anti-diabetic drugs.

We generated Sglt1 and Sglt2 knockout (KO) mice, Sglt1/Sglt2 double-KO (DKO) mice, and wild-type (WT) littermates to study their relative glycemic control and to determine contributions of SGLT1 and SGLT2 to UGE.
|
299 |
23149623
|
Sglt1 KOs fed glucose-free high-fat diet (G-free HFD) had improved oral glucose tolerance accompanied by delayed intestinal glucose absorption and increased circulating glucagon-like peptide-1 (GLP-1), but had normal intraperitoneal glucose tolerance.

LX4211-treated mice and SGLT1-/- mice had increased levels of plasma GLP-1, plasma PYY, and intestinal glucose during the 6 hours after a glucose-containing meal, as reflected by area under the curve (AUC) values, whereas SGLT2-/- mice showed no response.
|

In addition, ipragliflozin reduced plasma and liver levels of oxidative stress biomarkers (thiobarbituric acid reactive substances and protein carbonyl) and inflammatory markers (interleukin 6, tumor necrosis factor α, monocyte chemotactic protein-1, and c-reactive protein), and improved liver injury as assessed by plasma levels of aminotransferases.

Inhibition of SGLT2 lowers blood glucose in an insulin independent manner as a consequence of blocking reabsorption of filtered glucose in the glomeruli, thereby increasing urinary excretion of glucose and, in turn, potentially reducing bodyweight.

Data from these trials suggest that SGLT-2 inhibitors are able to lower hemoglobin A1c and fasting blood glucose when used as either monotherapy or combination therapy.

These studies indicate that inducing glycosuria by suppressing SGLT2 can reduce plasma glucose and A1c levels, as well as decrease weight, resulting in improved β-cell function and enhanced insulin sensitivity in liver and muscle.

Because the mechanism of SGLT2 inhibition is independent of insulin secretion and sensitivity, these agents can be combined with other antidiabetic agents, including exogenous insulin.

In this substrate specificity study, we examined the interactions of imino sugars with a novel human glucose sensor, sodium/glucose cotransporter type 3 (hSGLT3), using expression in Xenopus laevis oocytes and electrophysiology.

The results for hSGLT3 are compared with those for alpha-glucosidases and human SGLT type 1 (hSGLT1), a well characterized sodium/glucose cotransporter of the SGLT family.

In general, substrates have lower apparent affinities (K0.5) for hSGLT3 than hSGLT1 (D-glucose, alpha-methyl-D-glucose, 1-deoxy-D-glucose, and 4-deoxy-4-fluoro-D-glucose exhibit K0.5 values of 19, 21, 43, and 17 mM, respectively, for hSGLT3, and 0.5, 0.7, 10, and 0.07 mM, respectively, for hSGLT1).

However, specificity of hSGLT3 binding is greater (D-galactose and 4-deoxy-4-fluoro-D-galactose are not hSGLT3 substrates, but have hSGLT1 K0.5 values of 0.6 and 1.3 mM).

This work provides insights into hSGLT3 and -1 substrate binding interactions, establishes a pharmacological profile to study endogenous hSGLT3, and may have important ramifications for the clinical application of imino sugars.
