In this study, we examined the potential role of serine/threonine protein phosphatase-1 (PP-1) and PP-2A in the mechanism of Na+/K+-ATPase activation by insulin in the rat skeletal muscle cell line L6.

|
Immunoprecipitation of the enzyme from 32P-labeled cells with an antibody directed against the alpha-1 subunit of the enzyme revealed a 60% decrease in 110-kDa protein phosphorylation in insulin-treated cells.
|
29 |
9295306
|
To further confirm the role of PP-1, we used L6 cell lines that overexpress the glycogen/SR-associated regulatory subunit of PP-1, PP-1G.
|
30 |
9295306
|
Overexpression of PP-1G resulted in a 3-fold increase in insulin-stimulated PP-1 catalytic activity.
|
31 |
9295306
|
Inhibition of phosphatidylinositol-3 kinase with wortmannin blocked insulin-stimulated PP-1 activation as well as the dephosphorylation and activation of Na+/K+-ATPase.
|
32 |
9295306
|
We conclude that insulin regulates the activity of Na+/K+-ATPase by promoting dephosphorylation of the alpha subunit via an insulin-stimulated PP-1 and that phosphatidylinositol-3 kinase-generated signals may mediate insulin activation of PP-1 and Na+/K+-ATPase.

Serum sialic acid was confirmed as a marker of the acute-phase response since serum concentrations were significantly related to established acute-phase proteins such as alpha-1 acid glycoprotein (r = 0.82, p < 0.0001).

Evidence for defects in the trafficking and translocation of GLUT4 glucose transporters in skeletal muscle as a cause of human insulin resistance.
|
41 |
9616209
|
Since muscle GLUT4 glucose transporter levels are normal in type 2 diabetes, we have tested the hypothesis that insulin resistance is due to impaired translocation of intracellular GLUT4 to sarcolemma.
|
42 |
9616209
|
In equilibrium fractions from basal muscle, GLUT4 was decreased by 25-29% in both 25 and 28% sucrose density fractions and increased twofold in both the 32% sucrose fraction and bottom pellet in diabetics compared with insulin-sensitive controls, without any differences in membrane markers (phospholemman, phosphalamban, dihydropyridine-binding complex alpha-1 subunit).
|
43 |
9616209
|
Thus, insulin resistance was associated with redistribution of GLUT4 to denser membrane vesicles.
|
44 |
9616209
|
No effects of insulin stimulation on GLUT4 localization were observed.
|
45 |
9616209
|
In non-equilibrium fractions, insulin led to small GLUT4 decrements in the 25 and 28% sucrose fractions and increased GLUT4 in the 32% sucrose fraction by 2.8-fold over basal in insulin-sensitive but only by 1.5-fold in both insulin-resistant and diabetic subgroups.
|
46 |
9616209
|
Similar to GLUT4, the insulin-regulated aminopeptidase (vp165) was redistributed to a dense membrane compartment and did not translocate in response to insulin in insulin-resistant subgroups.
|
47 |
9616209
|
In conclusion, insulin alters the subcellular localization of GLUT4 vesicles in human muscle, and this effect is impaired equally in insulin-resistant subjects with and without diabetes.
|
48 |
9616209
|
Based on these data, we propose that human insulin resistance involves a defect in GLUT4 traffic and targeting leading to accumulation in a dense membrane compartment from which insulin is unable to recruit GLUT4 to the cell surface.

Although insulin has been shown to raise plasma concentrations of endothelin (ET) and up regulate vascular smooth muscle ETA receptor expression, the interaction of vanadate, an insulinomimetic agent, with the vascular ET system has not been investigated.
|
51 |
9794113
|
We compared the effects of oral vanadate treatment (0.5 mg/ml; p.o.) and insulin infusion (12 mU.kg-1.min-1 s.c.) for two weeks on plasma ET concentrations and vascular responses to endothelin-1 (ET-1) and the alpha-1 adrenoceptor agonist, methoxamine, in aortic ring preparations from streptozotocin (STZ) diabetic and non-diabetic adult male Sprague-Dawley rats.

Type II (non-insulin-dependent) diabetes mellitus is associated with increased blood concentrations of markers of the acute-phase response, including sialic acid, alpha-1 acid glycoprotein, serum amyloid A, C-reactive protein and cortisol, and the main cytokine mediator of the response, interleukin-6.

In this study, we observed its expression in nonobese diabetic (NOD) mouse IEC, in relation to the occurrence of type 1 diabetes and in response to cytokines, namely IL-1 beta and IL-10.
|
60 |
11891856
|
Furthermore, in cultured NOD IEC, Api expression is downregulated by the addition of IL-1 beta and is upregulated by IL-10; it is always absent in IL-10-deficient NOD mice and overexpressed in IL-10 transgenic NODs, thus further supporting that this cytokine upregulates Api expression.

Chromium picolinate inhibits resistin secretion in insulin-resistant 3T3-L1 adipocytes via activation of amp-activated protein kinase.
|
151 |
19298540
|
Using normal and insulin-resistant 3T3-L1 adipocytes, we examined the effects of CrPic on the gene transcription and secretion of adiponectin and resistin.
|
152 |
19298540
|
In addition, using immunoblotting, ELISA and real-time reverse transcription-polymerase chain reaction (RT-PCR), we investigated the effects of 10 nmol/L CrPic for 24 h on AMP-activated protein kinase (AMPK) to determine whether this pathway contributed to the regulation of adiponectin and resistin expression and secretion. 3.
|
153 |
19298540
|
Chromium picolinate did not modulate the expression of adiponectin and resistin; however, it did significantly inhibit the secretion of resistin, but not adiponectin, by normal and insulin-resistant 3T3-L1 adipocytes in vitro.
|
154 |
19298540
|
Furthermore, although CrPic markedly elevated levels of phosphorylated AMPK and acetyl CoA carboxylase in 3T3-L1 adipocytes, it had no effect on the levels of AMPK alpha-1 and alpha-2 mRNA transcripts.
|
155 |
19298540
|
Importantly, inhibition of AMPK by 2 h pretreatment of cells with 20 micromol/L compound C completely abolished the CrPic-induced suppression of resistin secretion. 4.
|
156 |
19298540
|
In conclusion, the data suggest that CrPic inhibits resistin secretion via activation of AMPK in normal and insulin-resistant 3T3-L1 adipocytes.

This process involves increased activity of alkaline phosphatase and increased expression of core binding factor alpha-1, a bone-specific transcription factor, with the subsequent induction of osteocalcin.
|
158 |
19423691
|
In addition, osteoblastic transformation of HSMCs provoked by elevated Pi (assessed by upregulation of core binding factor alpha-1, osteocalcin, and alkaline phosphatase activity) was diminished by ferritin/ferroxidase activity.
|
159 |
19423691
|
We conclude that induction of the HO-1/ferritin system prevents Pi-mediated calcification and osteoblastic differentiation of human smooth muscle cells mainly via the ferroxidase activity of ferritin.

|
Human maltase-glucoamylase (MGAM) and sucrase-isomaltase (SI) are small intestinal enzymes that work concurrently to hydrolyze the mixture of linear alpha-1,4- and branched alpha-1,6-oligosaccharide substrates that typically make up terminal starch digestion products.
|
165 |
20356844
|
The N-terminal catalytic domain of human MGAM (ntMGAM) has a preference for short linear alpha-1,4-oligosaccharides, whereas N-terminal SI (ntSI) has a broader specificity for both alpha-1,4- and alpha-1,6-oligosaccharides.

Adipose Orm levels were elevated by metabolic signals, including insulin, high glucose, and free fatty acid, as well as by the proinflammatory cytokine tumor necrosis factor-alpha, which is found in increased levels in the adipose tissue of morbid obese subjects.
|
171 |
20442402
|
In both adipocytes and macrophages, ORM suppressed proinflammatory gene expression and pathways such as NF-kappaB and mitogen-activated protein kinase signalings and reactive oxygen species generation.
|
172 |

|
Concomitantly, ORM relieved hyperglycemia-induced insulin resistance as well as tumor necrosis factor-alpha-mediated lipolysis in adipocytes.
