1 11027633 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.

138 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.
139 12032139 Increased p38 signaling may be responsible for the increased iNOS expression in SOCS-1-/- islets.

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.

219 12847226 Thyrotropin-mediated repression of class II trans-activator expression in thyroid cells: involvement of STAT3 and suppressor of cytokine signaling.
220 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.
225 12882919 We demonstrated that mice harboring beta-cells that do not respond to IFN because of the expression of the suppressor of cytokine signaling-1 (SOCS-1) succumb to an acute form of type 1 diabetes after infection with CVB3.

401 16574667 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.
410 16936188 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.
412 17010638 Attenuation of leptin and insulin signaling by SOCS proteins.
413 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).

431 18171427 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.

478 19008912 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 19008912 Insulin directly increased STAT5 and SOCS2 expression in mesangial cells.
483 19008912 This study shows that insulin can inhibit the mitogenic action of IGF-1 in mesangial cells by regulating STAT5/SOCS2 expression.
484 19008912 Insulin deficiency may contribute to the mesangial expansion found in diabetes through reduced STAT5/SOCS2 expression.

491 19414010 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 19587264 These defects were associated with decreased GLUT4 protein, reduced phosphatidylinositol 3-kinase activity, and alterations in the phosphorylation status of insulin receptor substrate 1 (IRS1).
497 19587264 Activation of c-Jun N-terminal kinase 1/2, which can phosphorylate IRS1 on Ser307, was significantly higher in TH mice compared with B6 controls.

500 19587264 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.
