Liver-derived hyperleptinemia in obese rats caused only a 5-7% loss of body weight, compared to a 13% loss in normoleptinemic lean animals; but in actual grams of weight lost there was no significant difference between obese and lean groups, suggesting that a subset of cells remain leptin-sensitive in obesity. mRNA and protein of a putative leptin-resistance factor, suppressor of cytokine signaling (SOCS)-1 or -3, were both increased in white adipose tissues (WAT) of VMH and DIO rats.

|
Since transgenic overexpression of SOCS-3 in islets reduced the lipopenic effect of leptin by 75%, we conclude that the increased expression of SOCS-1 and -3 in WAT of rats with acquired obesity could have blocked leptin's lipopenic action in the leptin-resistant WAT population.

Cytokines, such as tumor necrosis factor-alpha, interleukin-1 beta, and interleukin-6, and hormones, such as growth hormone, are known to cause insulin resistance, but the mechanisms by which they inhibit the cellular response to insulin have not been elucidated.
|

11342531
|
SOCS proteins are therefore attractive candidates as mediators of cytokine-induced insulin resistance.
|
7 |
11342531
|
We have found that SOCS-1 and SOCS-6 interact with the IR when expressed in human hepatoma cells (HepG2) or in rat hepatoma cells overexpressing the human IR.
|
8 |
11342531
|
In SOCS-1-expressing cells, insulin treatment increases the extent of interaction with the IR, whereas in SOCS-6-expressing cells the association with the IR appears to require insulin treatment.
|
9 |
11342531
|
SOCS-1 and SOCS-6 do not inhibit insulin-dependent IR autophosphorylation, but both proteins inhibit insulin-dependent activation of ERK1/2 and protein kinase B in vivo and IR-directed phosphorylation of IRS-1 in vitro.
|
10 |
11342531
|
These results suggest that SOCS proteins may be inhibitors of IR signaling and could mediate cytokine-induced insulin resistance and contribute to the pathogenesis of type II diabetes.

SOCS-1 protein prevents Janus Kinase/STAT-dependent inhibition of beta cell insulin gene transcription and secretion in response to interferon-gamma.
|
24 |
11342558
|
Interferon (IFN)-gamma, tumor necrosis factor-alpha and interleukin (IL)-1 beta play important, although not completely defined, roles in these mechanisms.
|
25 |
11342558
|
Here, using the highly differentiated beta Tc-Tet insulin-secreting cell line, we showed that IFN-gamma dose- and time-dependently suppressed insulin synthesis and glucose-stimulated secretion.
|
26 |
11342558
|
As described previously IFN-gamma, in combination with IL-1 beta, also induces inducible NO synthase expression and apoptosis (Dupraz, P., Cottet, S., Hamburger, F., Dolci, W., Felley-Bosco, E., and Thorens, B. (2000) J.
|
27 |

|
To assess the role of the Janus kinase/signal transducer and activator of transcription (STAT) pathway in IFN-gamma intracellular signaling, we stably overexpressed SOCS-1 (suppressor of cytokine signaling-1) in the beta cell line.
|
28 |
11342558
|
We demonstrated that SOCS-1 suppressed cytokine-induced STAT-1 phosphorylation and increased cellular accumulation.
|
29 |
11342558
|
This was accompanied by a suppression of the effect of IFN-gamma on: (i) reduction in insulin promoter-luciferase reporter gene transcription, (ii) decrease in insulin mRNA and peptide content, and (iii) suppression of glucose-stimulated insulin secretion.
|
30 |
11342558
|
Furthermore, SOCS-1 also suppressed the cellular effects that require the combined presence of IL-1 beta and IFN-gamma: induction of nitric oxide production and apoptosis.
|
31 |
11342558
|
Together our data demonstrate that IFN-gamma is responsible for the cytokine-induced defect in insulin gene expression and secretion and that this effect can be completely blocked by constitutive inhibition of the Janus kinase/STAT pathway.

|
In this study, we have shown that IFN-gamma signaling, measured by signal transducer and activator of transcription-1 (STAT1) activation and the expression of IFN-gamma-responsive genes, is persistent in beta-cells for as long as the cytokine is present.
|
60 |
11723057
|
Because members of the suppressor of cytokine signaling (SOCS) family may regulate the duration of IFN-gamma signaling, their expression was investigated in beta-cells.
|
61 |
11723057
|
We found that cytokine-inducible SH2-containing protein, SOCS-1, and SOCS-2 are expressed in primary islets and NIT-1 insulinoma cells, both at the mRNA and protein levels, after treatment with IFN-gamma and other proinflammatory cytokines.
|
62 |
11723057
|
Transfected SOCS-1 was found to inhibit responses to IFN-gamma in NIT-1 insulinoma cells, including STAT1 activation, class I major histocompatibility complex upregulation, and IFN-gamma-induced cell death, but only when expressed at levels higher than those found in untransfected cells.
|
63 |
11723057
|
Consistent with this, IFN-gamma signaling was not affected in SOCS-1-deficient beta-cells.
|
64 |
11723057
|
Therefore, persistent IFN-gamma signaling in beta-cells is associated with SOCS-1 expression that is not sufficient to terminate signaling.
|
65 |
11723057
|
Because overexpression of SOCS-1 can suppress responses to IFN-gamma, this may be a useful strategy for protecting beta-cells from cytotoxicity mediated by IFN-gamma and possibly other proinflammatory cytokines.

Decreased IR, IRS-1, and IRS-2 tyrosyl phosphorylation in response to insulin was found in skeletal muscle, whereas a chronic activation of the IRS-PI 3-kinase pathway was found in liver.

Suppressor of cytokine signaling-1 regulates the sensitivity of pancreatic beta cells to tumor necrosis factor.
|
97 |
12032139
|
By studying the effects of SOCS-1 deficiency, we investigated whether SOCS-1 is involved in preventing cytokine-induced death of pancreatic islet cells, a potential mechanism of insulin deficiency in autoimmune diabetes.
|
98 |
12032139
|
Tumor necrosis factor (TNF) + interferon-gamma (IFNgamma) was more potent at inducing cell death in SOCS-1-/- islets than in wild type.
|
99 |
12032139
|
Interleukin-1 + IFNgamma induced the same level of cell death in SOCS-1-/- and wild-type islets, suggesting that the sensitivity of islets to IFNgamma or interleukin-1-mediated cytotoxicity is not affected by SOCS-1 deficiency.
|
100 |
12032139
|
Additionally, SOCS-1-/- beta cells were responsive to lower concentrations of TNF measured by class I major histocompatibility complex up-regulation.
|
101 |
12032139
|
The TNF + IFNgamma damage of islets was mediated by inducible nitric-oxide synthase (iNOS), and increased iNOS expression and nitric oxide production were found in SOCS-1-/- islets following cytokine treatment.
|
102 |
12032139
|
A further analysis revealed that SOCS-1 deficiency results in augmented TNF signaling via the p38 mitogen-activated protein kinase pathway but not NFkappaB or c-Jun N-terminal kinase pathways.
|
103 |
12032139
|
Increased p38 signaling may be responsible for the increased iNOS expression in SOCS-1-/- islets.
|
104 |
12032139
|
Therefore, these findings provide evidence that physiological levels of SOCS-1 negatively regulate TNF signaling.

Tumor necrosis factor (TNF) + interferon-gamma (IFNgamma) was more potent at inducing cell death in SOCS-1-/- islets than in wild type.
|
126 |
12032139
|
Interleukin-1 + IFNgamma induced the same level of cell death in SOCS-1-/- and wild-type islets, suggesting that the sensitivity of islets to IFNgamma or interleukin-1-mediated cytotoxicity is not affected by SOCS-1 deficiency.
|
127 |
12032139
|
Additionally, SOCS-1-/- beta cells were responsive to lower concentrations of TNF measured by class I major histocompatibility complex up-regulation.
|
128 |
12032139
|
The TNF + IFNgamma damage of islets was mediated by inducible nitric-oxide synthase (iNOS), and increased iNOS expression and nitric oxide production were found in SOCS-1-/- islets following cytokine treatment.
|
129 |
12032139
|
A further analysis revealed that SOCS-1 deficiency results in augmented TNF signaling via the p38 mitogen-activated protein kinase pathway but not NFkappaB or c-Jun N-terminal kinase pathways.
|
130 |
12032139
|
Increased p38 signaling may be responsible for the increased iNOS expression in SOCS-1-/- islets.
|
131 |
12032139
|
Therefore, these findings provide evidence that physiological levels of SOCS-1 negatively regulate TNF signaling.

SOCS-1 and SOCS-3 block insulin signaling by ubiquitin-mediated degradation of IRS1 and IRS2.
|
178 |
12228220
|
We show that SOCS1 or SOCS3 targeted IRS1 and IRS2, two critical signaling molecules for insulin action, for ubiquitin-mediated degradation.
|
179 |
12228220
|
SOCS1 or SOCS3 bound both recombinant and endogenous IRS1 and IRS2 and promoted their ubiquitination and subsequent degradation in multiple cell types.
|
180 |
12228220
|
Mutations in the conserved SOCS box of SOCS1 abrogated its interaction with the elongin BC ubiquitin-ligase complex without affecting its binding to IRS1 or IRS2.
|
181 |
12228220

The SOCS1 mutants also failed to promote the ubiquitination and degradation of either IRS1 or IRS2.

Adenoviral-mediated expression of SOCS1 in mouse liver dramatically reduced hepatic IRS1 and IRS2 protein levels and caused glucose intolerance; by contrast, expression of the SOCS1 mutants had no effect.

Thus, SOCS-mediated degradation of IRS proteins, presumably via the elongin BC ubiquitin-ligase, might be a general mechanism of inflammation-induced insulin resistance, providing a target for therapy.

12847226

Thyrotropin (TSH) represses IFN-gamma-induced CIITA expression by inhibiting type IV CIITA promoter activity through the suppression of STAT1 activation and IFN regulatory factor 1 induction.
|
221 |
12847226
|
This study found that TSH induces transcriptional activation of the STAT3 gene through the phosphorylation of STAT3 and CREB activation.
|
222 |
12847226

TSH induces SOCS-1 and SOCS-3, and TSH-mediated SOCS-3 induction was dependent on STAT3.
|
223 |
12847226
|
The cell line stably expressing the wild-type STAT3 showed a higher CIITA induction in response to IFN-gamma and also exhibited TSH repression of the IFN-gamma-mediated induction of CIITA.
|
224 |
12847226
|
However, TSH repression of the IFN-gamma-induced CIITA expression was not observed in FRTL-5 thyroid cells, which stably expresses the dominant negative forms of STAT3, STAT3-Y705F, and STAT3-S727A.

Here we show that in both obesity and lipopolysaccharide (LPS)-induced endotoxemia there is an increase in suppressor of cytokine signaling (SOCS) proteins, SOCS-1 and SOCS-3, in liver, muscle, and, to a lesser extent, fat.

In this study, we show that expression of suppressor of cytokine signaling SOCS-1 and SOCS-3 is increased in livers of obese insulin-resistant animals, and that adenoviral-mediated overexpression of SOCS-1 or SOCS-3 in liver causes insulin resistance through down-regulation of tyrosine phosphorylation of insulin receptor substrate (IRS) proteins.
|
384 |
16226915
|
Moreover, the increased SOCS-1 and SOCS-3 also cause a prominent up-regulation of the key regulator of fatty acid synthesis in liver, sterol regulatory element binding protein (SREBP)-1.
|
385 |
16226915
|
Conversely, inhibition of SOCS-1 and SOCS-3 in livers of obese diabetic db/db mice by antisense treatment modestly improves insulin sensitivity, but completely normalizes the increased expression of SREBP-1.
|
386 |
16226915
|
Promoter activity analysis reveals that expression of SOCS-1 or SOCS-3 with SOCS-3 being more potent enhances SREBP-1c expression, while it is inhibited by expression of STAT3.
|
387 |
16226915
|
This STAT3-mediated inhibition of SREBP-1c expression is antagonized by co-expression of SOCS proteins.
|
388 |
16226915
|
Moreover, db/db mice display decreased STAT3 phosphorylation in liver that is normalized by antisense treatment of SOCS proteins.
|
389 |
16226915
|
These data suggest that obese subjects in the persistent inflammatory states, such as elevated circulating tumor necrosis factor-alpha, may have down-regulated STAT3-mediated signaling by increased SOCS proteins, leading to up-regulation of SREBP-1c expression and increased fatty acid synthesis in liver.
|

Thus, SOCS proteins play an important role in pathogenesis of the metabolic syndrome by concordantly modulating cytokine signaling and insulin signaling.

Perforin and Fas induced by IFNgamma and TNFalpha mediate beta cell death by OT-I CTL.
|
402 |
16574667
|
It was also prevented by pre-incubation with anti-tumor necrosis factor-alpha (anti-TNFalpha) antibody or by blocking IFNgamma responsiveness through expressing a dominant negative IFNgamma receptor.
|
403 |
16574667
|
Perforin-deficient CTL produced IFNgamma and TNFalpha that was shown to directly induce islet Fas expression during the assays.
|
404 |
16574667
|
This suggests that Fas-deficiency, SOCS-1 overexpression and blockade of IFNgamma and TNFalpha all protect beta cells from residual cytotoxicity of perforin-deficient CTL by blocking Fas upregulation.
|
405 |
16574667
|
However, in the absence of perforin, the Fas/FasL pathway provides an alternative mechanism dependent on islet cell Fas upregulation by cytokines IFNgamma and TNFalpha.
|
406 |
16757551
|
Expression of the following signal proteins were assayed by Western blotting: STAT5/p-STAT5, MAPK, and Akt/PKB.
|
407 |
16757551
|
STAT5 DNA binding activity was assessed with EMSA, and the expression of IGF-I and SOCS mRNA was measured by real-time RT-PCR.
|
408 |
16757551
|
GH-induced STAT5 DNA binding and expression of IGF-I mRNA were detected in fat, whereas expression of SOCS-1 and -3 tended to increase after GH in muscle and fat, respectively.
|
409 |
16757551
|
We conclude that 1) STAT5 is acutely activated in human muscle and fat after a GH bolus, but additional downstream GH signaling was significant only in fat; 2) the direct GH effects in muscle need further characterization; and 3) this human in vivo model may be used to study the mechanisms subserving the actions of GH on substrate metabolism and insulin sensitivity in muscle and fat.

We have examined the contribution of perforin and Fas ligand to beta-cell destruction using islet-specific CD8(+) T-cells from T-cell receptor transgenic NOD8.3 mice.
|
411 |
16936188
|
Therefore, NOD8.3 T-cells use both perforin and Fas pathways to kill beta-cells and the surprising blockade of NOD8.3 T-cell-mediated beta-cell death by SOCS-1 overexpression may be due in part to reduced target cell recognition.

Attenuation of leptin and insulin signaling by SOCS proteins.
|

17010638
|
Leptin and insulin are key hormones involved in the regulation of energy balance and glucose homeostasis.
|
414 |
17010638
|
Specific members of the suppressor of cytokine signaling (SOCS) family of proteins are now thought to have a role in the development of leptin and insulin resistance owing to their ability to inhibit leptin and insulin signaling pathways.
|
415 |
17010638
|
In the case of leptin, current evidence suggests that SOCS3 appears to be of particular importance in the development of leptin resistance, whereas the ability to diminish insulin action has been described for several SOCS proteins (SOCS1, SOCS3, SOCS6 and SOCS7).

Not only absence of MHC-I and Fas upregulation, but also resistance to cytokine-induced killing of beta-cells and a complete lack of CXCL-10 (IP10) production in islets led to a lack of islet infiltration and impaired activation of autoaggressive CD4(+) and CD8(+) T-cells in these mice.

SOCS proteins causing trouble in insulin action.
|
432 |
18171427
|
SOCS-1 and SOCS-3 have been extensively studied both in vitro and in vivo in the context of insulin action.
|
433 |
18171427
|
It has been shown that these two SOCS members are able to inhibit the insulin signalling pathway by three different mechanisms: (1) inhibition of tyrosine phosphorylation of insulin receptor substrate (IRS) proteins because of competition at the docking site on the insulin receptor (IR), (2) induction of the proteasomal degradation of the IRS and (3) inhibition of the IR kinase.
|
434 |
18171427
|
A significant correlation between SOCS-3 expression and insulin resistance has been demonstrated in vivo.
|
435 |
18171427
|
Interestingly, the level of SOCS-3 expression is strikingly enhanced in insulin-sensitive tissues from both patients and animal models with type 2 diabetes and insulin resistance.
|
436 |
18171427
|
While it remains to be established whether the increased expression of SOCS is a cause or a consequence of insulin resistance, a large body of observations supports a role for SOCS proteins in the disease process found in states with insulin resistance.

SOCS-1 deficiency does not prevent diet-induced insulin resistance.
|
451 |
18929539
|
Obesity is associated with inflammation and increased expression of suppressor of cytokine signaling (SOCS) proteins, which inhibit cytokine and insulin signaling.
|
452 |
18929539
|
Thus, reducing SOCS expression could prevent the development of obesity-induced insulin resistance.
|
453 |
18929539
|
Using SOCS-1 knockout mice, we investigated the contribution of SOCS-1 in the development of insulin resistance induced by a high-fat diet (HFD).
|
454 |
18929539
|
This was accompanied by increased mRNA expression of leptin and the macrophage marker CD68 in white adipose tissue and of SREBP1c and FAS in liver.
|
455 |
18929539

HFD also induced hyperglycemia in SOCS-1 deficient mice with impairment of glucose and insulin tolerance tests.

Insulin regulates SOCS2 expression and the mitogenic effect of IGF-1 in mesangial cells.
|
479 |
19008912
|
Using DNA microarray analysis of glomerular RNA from control and diabetic rats we found that the expression levels of insulin-like growth factor 1 receptor (IGF-1R) were increased while those of suppressor of cytokine signaling 2 (SOCS2) and STAT5 were decreased.
|
480 |
19008912
|
Overexpression of SOCS2 in rat mesangial cells inhibited IGF-1-induced activation of extracellular signal-regulated kinase, which subsequently reduced type IV collagen and DNA synthesis, an effect due to interaction of SOCS2 with IGF-1R.
|
481 |
19008912
|
Inhibition of SOCS2 overexpression by small interfering RNA suppressed IGF-1R-mediated actions by preventing phosphorylation of tyrosine 317 in the p66Shc adaptor protein; however, overexpression of either SOCS1 or SOCS3 did not affect IGF-1R signaling.
|
482 |

Insulin directly increased STAT5 and SOCS2 expression in mesangial cells.

We studied the expression of a set of selected genes involved in apoptosis (Bcl2, Bclx(L), Bax, Bad, Bid, and CHOP), cytokine defense, (SOCS-1 and SOCS-3), or free radical protection (Hmox1, Cu/Zn-SOD, Mn-SOD, and Hsp70).
|
486 |
19177839
|
The expression of proapoptotic genes Bid and CHOP, as well as protective genes Bclx(L), Socs1, Socs3, Hmox1, and MnSod, was maximally increased 1 day after transplantation, and in most cases it remained increased 7 days later, indicating the presence of a protective response against cell damage.
|

JANEX-1, a JAK3 inhibitor, protects pancreatic islets from cytokine toxicity through downregulation of NF-kappaB activation and the JAK/STAT pathway.
|
492 |
19414010
|
The molecular mechanism by which JANEX-1 inhibits iNOS expression was mediated through suppression of the nuclear factor kappaB (NF-kappaB) and JAK/signal transducer and activator of transcription (STAT) pathways.
|
493 |
19414010
|
Islets treated with the cytokines downregulated the protein levels of suppressor of cytokine signaling (SOCS)-1 and SOCS-3, but pretreatment with JANEX-1 attenuated these decreases.
|
494 |
19414010
|
These results demonstrate that JANEX-1 protects beta-cells from cytokine toxicity through suppression of the NF-kappaB and JAK/STAT pathways and upregulation of SOCS proteins, suggesting that JANEX-1 may be used to preserve functional beta-cell mass.

|
496 |

Suppressor of cytokine signaling 1, known to promote IRS1 ubiquitination and subsequent degradation, was found at significantly higher levels in TH mice compared with B6.
|

Our findings suggest that increased IRS1 degradation and subsequent impaired GLUT4 mobilization play a role in the reduced glucose uptake in insulin resistant TH mice.

We demonstrate that SOCS-1 does not prevent increase in NO production and decrease in glucose-stimulated insulin secretion in the presence of IL-1beta, IFNgamma, TNFalpha.
|

Our data suggest that SOCS-1 overexpression may not be sufficient in preventing all the biological activities of IFNgamma in beta cells.

Regulation of cytokine-driven functional differentiation of CD8 T cells by suppressor of cytokine signaling 1 controls autoimmunity and preserves their proliferative capacity toward foreign antigens.
|
548 |
20519645
|
We have previously shown that naive CD8 T cells exposed to IL-7 or IL-15 in the presence of IL-21 undergo Ag-independent proliferation with concomitant increase in TCR sensitivity.
|
549 |
20519645
|
In this study, we examined whether CD8 T cells that accumulate in suppressor of cytokine signaling 1 (SOCS1)-deficient mice because of increased IL-15 signaling in vivo would respond to an autoantigen expressed at a very low level using a mouse model of autoimmune diabetes.
|
550 |
20519645
|
In this model, P14 TCR transgenic CD8 T cells (P14 cells) adoptively transferred to rat insulin promoter-glycoprotein (RIP-GP) mice, which express the cognate Ag in the islets, do not induce diabetes unless the donor cells are stimulated by exogenous Ag.
|
551 |
20519645

Surprisingly, SOCS1-deficient P14 cells, which expanded robustly following IL-15 stimulation, proliferated poorly in response to Ag and failed to cause diabetes in RIP-GP mice.

552 |
20519645
|
SOCS1-deficient CD8 T cells expressing a polyclonal TCR repertoire also showed defective expansion following in vivo Ag stimulation.

Notwithstanding the Ag-specific proliferation defect, SOCS1-null P14 cells produced IFN-gamma and displayed potent cytolytic activity upon Ag stimulation, suggesting that SOCS1-null CD8 T cells underwent cytokine-driven functional differentiation that selectively compromised their proliferative response to Ag but not to cytokines.
|
554 |

These findings suggest that by attenuating cytokine-driven proliferation and functional differentiation, SOCS1 not only controls the pathogenicity of autoreactive cells but also preserves the ability of CD8 T cells to proliferate in response to Ags.
