7883112
|
The concentration of C/EBP beta mRNA in the liver of mice and rats fed a high-carbohydrate diet, which causes a rise in blood insulin levels, was lower (80 and 65%, respectively) than that detected in animals fed a standard diet.
|
5 |
7883112
|
Similarly, the expression of the human insulin gene in the liver of transgenic mice led to a decrease in the concentration of C/EBP beta mRNA.
|
6 |
7883112
|
Furthermore, the expression of the C/EBP beta gene increased in the liver of diabetic rats and decreased in the liver of diabetic animals treated with vanadate, an insulin mimetic agent.
|
7 |
7883112
|
In addition, a decrease in C/EBP beta protein was observed in liver nuclei from mice after insulin injections, in mice fed a high-carbohydrate diet, and in transgenic mice expressing the insulin gene in the liver.
|

To evaluate the potential for regulation of the insulin receptor substrate IRS-1, we have cloned the mouse IRS-1 gene, identified its promoter, and analyzed promoter activity in the basal state and in response to stimulation.
|
45 |
8544845
|
The 5'-region of the mouse IRS-1 gene lacks typical CAAT and TATA boxes but contains nine potential Sp1 binding sites consistent with a housekeeping gene.
|
46 |
8544845
|
The 5'-region of the IRS-1 gene also has significant regions of homology with the promoters of the progesterone receptor gene, the insulin-like growth factor I receptor gene, and the androgen receptor gene.
|
47 |

|
By gel shift assay, a nuclear factor was identified in CHO cells which binds to -1606 and -1586 sequence in the negative regulatory element and appears to be distinct from C/EBP, CREB, and AP-1.
|
48 |
8544845
|
Insulin also decreased IRS-1 protein by approximately 60% within 9 h but did so without altering IRS-1 mRNA levels or chloramphenicol acetyl transferase activity.
|
49 |
8544845
|
Thus, both insulin and dexamethasone down-regulate IRS-1 expression at the posttranscriptional level; with insulin this is probably due to an effect on protein half-life, whereas with dexamethasone the effect is due to a change in the half-life of IRS-1 mRNA.

Cell-specific regulation of IRS-1 gene expression: role of E box and C/EBP binding site in HepG2 cells and CHO cells.
|
51 |
9032089
|
CAT assays using promoters mutated at the E box or at the C/EBP binding site revealed that these sequences were responsible for cell-specific regulation of the IRS-1 gene.
|
52 |
9032089
|
We therefore concluded that the two nuclear proteins that bind to the E box regulate IRS-1 gene expression positively in HepG2 cells and the two nuclear proteins that bind to the C/EBP binding site regulate it negatively in CHO cells.

Regulation of leptin promoter function by Sp1, C/EBP, and a novel factor.
|
62 |
9492033
|
No effect on the transient expression of leptin was noted upon treatment with a thiazolidinedione, BRL49653, or upon cotransfection with peroxisome proliferator-activated receptor-gamma/retinoid X receptor-alpha or sterol response element-binding protein-1.
|
63 |
9492033
|
Mutations of the Sp1, LP1, and C/EBP sites in pairwise combinations diminished promoter activity to the extent predicted assuming these motifs contribute independently to leptin promoter function.

IRE-ABP (insulin response element-A binding protein), an SRY-like protein, inhibits C/EBPalpha (CCAAT/enhancer-binding protein alpha)-stimulated expression of the sex-specific cytochrome P450 2C12 gene.
|
68 |
9731699
|
In primary hepatocytes, overexpression of an insulin response element-A binding protein (IRE-ABP), a member of the SRY family of high-mobility group (HMG) proteins, inhibits CCAAT/enhancer-binding protein alpha (C/EBPalpha)-mediated activation of the female-specific cytochrome P450 2C12 (CYP2C12) gene, but not the male-specific cytochrome P450 2C11 (CYP2C11) gene.
|
69 |
9731699
|
Taken together, our findings suggest that SRY-like proteins can bind to a subset of sequences recognized by the C/EBP family of DNA-binding proteins and modulate gene transcription in a context-specific manner.

The transcription factor CCAAT/enhancer-binding protein beta regulates gluconeogenesis and phosphoenolpyruvate carboxykinase (GTP) gene transcription during diabetes.
|
73 |
10224054
|
CCAAT/enhancer-binding protein (C/EBP) beta and C/EBPalpha are members of the c/ebp gene family and are highly expressed in mammalian liver and adipose tissue.
|
74 |
10224054
|
C/EBPbeta binds to several sequences of the phosphoenolpyruvate carboxykinase (PEPCK) gene promoter with high affinity, and C/EBPbeta protein is increased 200% in the livers of streptozotocin-diabetic mice, concurrent with increased PEPCK mRNA.
|
75 |
10224054
|
We also examined the expression of PEPCK and glucose 6-phosphatase mRNAs and regulation of blood glucose, including the contribution of gluconeogenesis to blood glucose in c/ebpbeta-/- mice.
|
76 |
10224054
|
C/EBPbeta was not essential to basal PEPCK mRNA levels.
|
77 |
10224054
|
However, C/EBPbeta deletion affected streptozotocin-diabetic response by: (a) delaying hyperglycemia, (b) preventing the increase of plasma free fatty acids, (c) limiting the full induction of PEPCK and glucose 6-phosphatase genes, and (d) preventing the increase in gluconeogenesis rate.
|
78 |
10224054
|
Gel supershifts of transcription factor C/EBPalpha, bound to CRE, P3I, and AF-2 sites of the PEPCK promoter, was not increased in diabetic c/ebpbeta-/- mouse liver nuclei, suggesting that C/EBPalpha does not substitute for C/EBPbeta in the diabetic response of liver gene transcription.
|
79 |
10224054
|
These results link C/EBPbeta to the metabolic and gene regulatory responses to diabetes and implicate C/EBPbeta as an essential factor underlying glucocorticoid-dependent activation of PEPCK gene transcription in the intact animal.

Cytokine induction of Fas gene expression in insulin-producing cells requires the transcription factors NF-kappaB and C/EBP.
|
81 |
11473033
|
Fas-mediated cell death may play a role in the autoimmune destruction of pancreatic beta-cells in type 1 diabetes. beta-Cells do not express Fas under physiological conditions, but Fas mRNA and protein are induced in cytokine-exposed mouse and human islets, rendering the beta-cells susceptible to Fas ligand-induced apoptosis.

Regulation of aldehyde reductase expression by STAF and CHOP.
|
114 |
14667815
|
Gel-shift assays and chromatin immunoprecipitation as well as deletion/mutation analysis reveal that selenocysteine tRNA transcription activating factor (STAF) binds to the 5' element and drives constitutive expression of both mouse and human aldehyde reductase.
|
115 |
14667815
|
Aldehyde reductase thus becomes the fourth protein-encoding gene regulated by STAF.
|
116 |
14667815
|
The human, but not the mouse, promoter also binds C/EBP homologous protein (CHOP), which competes with STAF for the same binding site.
|
117 |
14667815
|
Transfection of the human promoter into ethoxyquin-treated mouse 3T3 cells induces a 3.5-fold increase in promoter activity and a CHOP-C/EBP band appears on gel shifts performed with the 5' probe from the human aldehyde reductase promoter.

The aims of this study were to clarify whether common mechanisms are involved in FFA- and cytokine-induced beta-cell apoptosis and determine whether TNFalpha, an adipocyte-derived cytokine, potentiates FFA toxicity through enhanced NF-kappaB activation.
|
124 |
15297438

Apoptosis was induced in insulinoma (INS)-1E cells, rat islets, and fluorescence-activated cell sorting-purified beta-cells by oleate, palmitate, and/or cytokines (IL-1beta, interferon-gamma, TNFalpha).

125 |
15297438
|
The NF-kappaB-dependent genes inducible nitric oxide synthase and monocyte chemoattractant protein-1 were induced by IL-1beta but not by FFAs.

Moreover, FFAs did not enhance NF-kappaB activation by TNFalpha.

Transcription factors such as CCAAT/enhancer-binding proteins (C/EBPs) and peroxisome proliferator-activated receptors (PPARs) are known to regulate genes associated with insulin resistance.
|
133 |
15479564
|
We found that a C/EBPbeta enhancer, prolactin, significantly induced the EC-SOD mRNA and protein levels in cultured fibroblast cell lines, but PPARgamma ligands, pioglitazone and other thiazolidinedione agents did not.
|
134 |
15479564
|
Deletion analysis of the EC-SOD promoter-luciferase construct showed that an important element responsible for prolactin is located between -242 and -178 in the promoter region of the EC-SOD gene in which a known C/EBPbeta-binding site is located.
|
135 |
15479564
|
Increasing the EC-SOD expression by treatment with ligands of transcription factors might be one approach to ameliorate the pathological conditions of insulin resistance.

Dehydroepiandrosterone (DHEA) exerts beneficial effects on blood glucose levels and insulin sensitivity in obese rodents and humans, resembling the effects of peroxisome proliferator-activated receptor-gamma (PPARgamma) ligands and opposing those of glucocorticoids; however, the underlying mechanisms remain unclear.
|
137 |
15613680
|
Analysis of the transcription factors involved in the DHEA-dependent regulation of 11beta-HSD1 expression revealed a switch in CCAAT/enhancer-binding protein (C/EBP) expression.
|
138 |
15613680
|
C/EBPalpha, a potent activator of 11beta-HSD1 gene transcription, was downregulated in 3T3-L1 adipocytes and in liver and adipose tissue of DHEA-treated mice, whereas C/EBPbeta and C/EBPdelta, attenuating the effect of C/EBPalpha, were unchanged or elevated.
|
139 |
15613680
|
Our results further suggest a protective effect of DHEA on adipose tissue by upregulating PPARalpha and downregulating leptin, thereby contributing to the reduced expression of 11beta-HSD1.
|

|
C/EBPalpha regulates human adiponectin gene transcription through an intronic enhancer.
|
141 |
15919796
|
Adiponectin is an adipose-derived hormone that enhances insulin sensitivity and plays an important role in regulating energy homeostasis.
|
142 |
15919796
|
Coexpression of CCAAT/enhancer-binding protein (C/EBP)alpha increased luciferase activity of the Pro-Int1-Luc construct approximately 75-fold but had no effect on the constructs containing the proximal adiponectin promoter alone.
|
143 |
15919796
|
Overexpression or siRNA-mediated knockdown of endogenous C/EBPalpha significantly increased or decreased, respectively, adiponectin mRNA levels in differentiated human Chub-S7 adipocytes, while neither C/EBPbeta nor C/EBPdelta significantly affected adiponectin expression in mature adipocytes.
|
144 |
15919796
|
Thus, C/EBPalpha is a key transcription factor for full activation of human adiponectin gene transcription in mature adipocytes through interaction with response elements in the intronic enhancer.

INS-1 cells exposed to palmitate for 16-24 h under serum-free conditions showed marked apoptosis and increased protein levels of phosphorylated eukaryotic translation initiation factor 2alpha (eIF2alpha), activating transcription factor 4 (ATF4), X box-binding protein 1 (XBP-1), and C/EBP homologous transcription factor (CHOP) compared with control cells.
|
146 |
16601139
|
Unexpectedly, the levels of the ER chaperone proteins Grp78/BiP and PDI were not affected by palmitate treatment, suggesting that the cell protective aspects of the unfolded protein response (UPR) are not up-regulated by palmitate.
|

|
By using different luciferase constructs containing fragments of the hHSD11B1 promoter, we demonstrate that two members of the CCAAT/enhancer-binding protein family, C/EBPalpha and C/EBPbeta, are required for the basal transcriptional activity of HSD11B1 in 3T3-L1 preadipocyte cells.
|
148 |
16837116
|
By transfection studies using the hHSD11B1 luciferase constructs, it appears that C/EBPbeta was strongly involved in this induction, as the forskolin stimulation was suppressed after mutation of the C/EBPbeta binding site.
|
149 |
16837116
|
These data indicate that members of the C/EBP family control intracellular levels of GC in preadipocytes via the regulation of the constitutive and cAMP-dependent expressions of HSD11B1.

Dispersed transgenic islet cells lived only shortly, and several endoplasmic reticulum (ER) stress-related molecules such as immunoglobulin-binding protein (Bip), inositol-requiring enzyme-1alpha, X-box-binding protein-1 (XBP-1), RNA-activated protein kinase-like endoplasmic reticulum kinase, activating transcription factor-4, and C/EBP-homologous protein (CHOP) were more expressed in the transgenic islets.
|
151 |
17400804
|
In the quantitative real-time PCR analyses, the expression levels of Bip and CHOP were reduced in the islets from the transgenic mice treated with exendin-4.

To investigate whether selenium (Sel) treatment would impact on the onset of diabetes,we examined serum biochemical components including glucose and insulin,endoplasmic reticulum (ER) stress and insulin signalling proteins, hepatic C/EBP-homologous protein (CHOP) expression and DNA fragmentation in diabetic and non- diabetic conditions of non-obese diabetic (NOD) mice.
|
153 |
17762145
|
We conclude that (i) Sel treatment induced insulin-like effects in lowering serum glucose level in Sel-treated NOD mice, (ii) Sel-treated mice had significantly decreased serum biochemical components associated with liver damage and lipid metabolism, (iii) Sel treatment led to the activation of the ER stress signal through the phosphorylation of JNK and eIF2 protein and insulin signal mechanisms through the phosphorylation of Akt and PI3 kinase, and (iv) Sel-treated mice were significantly relieved apoptosis of liver tissues indicated by DNA fragmentation assay in the diabetic NOD group.

In our laboratory we have identified various factors that cooperate with the vitamin D receptor in regulating 24(OH)ase expression including C/EBP beta, SWI/SNF (complexes that remodel chromatin using the energy of ATP hydrolysis) and the methyltransferases, CARM1 and G9a.
|
155 |
18083936
|
Evidence is also presented for C/EBP beta as a nuclear coupling factor that coordinates regulation of osteopontin by 1,25(OH)(2)D(3) and PTH.

18981473
|
Bioinformatics analysis also revealed CCAAT/enhancer-binding protein (C/EBP)-binding motifs in the vicinity of most PPARgamma-binding sites, and genome-wide analysis of C/EBPalpha binding demonstrated that it localized to 3350 of the locations bound by PPARgamma.
|
163 |
18981473

C/EBPbeta also plays a role at many of these genes, such that both C/EBPalpha and beta are required along with PPARgamma for robust adipocyte-specific gene expression.

We then discovered that ER stress-induced apoptotic signaling through C/EBP-homologous protein (CHOP) occurs in Gimap5(-/-) T cells.
|
180 |
19424493

Knockdown of CHOP by siRNA protected Gimap5(-/-) T cells from ER stress-induced apoptosis, thereby identifying a role for this cellular pathway in the T cell lymphopenia of the BBDP rat.

PERK mediated eIF2alpha phosphorylation is also required for the expression of lipogenic genes and the development of hepatic steatosis, likely by activating C/EBP and PPARgamma transcription factors.

MCP-1 (monocyte chemotactic protein-1)-induced protein, a recently identified zinc finger protein, induces adipogenesis in 3T3-L1 pre-adipocytes without peroxisome proliferator-activated receptor gamma.
|
184 |
19666473
|
This process involves temporally regulated genes controlled by a set of transcription factors, CCAAT/enhancer-binding proteins (C/EBP) beta, C/EBPdelta, and C/EBPalpha and peroxisome proliferator-activated receptor gamma (PPARgamma).
|
185 |

GSA increased IL-8 transcription via promoter activation and enhanced CXCL8 release from VSMCs.
|
203 |
19733855
|
GSA-induced promoter activation of the IL-8 gene was suppressed by dominant-negative mutants of TLR-4, MyD88, and TRIF, but not by a dominant-negative form of TLR-2.
|
204 |
19733855
|
Mutation at the NF-kappaB- or C/EBP-binding site, but not at the AP-1-binding site, in the IL-8 promoter region suppressed GSA-induced promoter activation.
|
205 |
19733855
|
This study suggests that GSA induces expression of IL-8 in VSMCs and that TLR-4, mitogen-activated protein kinases, NF-kappaB, and NADPH oxidase are involved in that process.

For the in vivo studies, diabetes was induced in rats, and retinal expression of glucose-regulated protein 78 (GRP78), activating transcription factor 4 (ATF4), C/EBP homologous protein (CHOP), and vascular endothelial growth factor (VEGF) in groups of rats at 1, 3, and 6 months was assessed.
|
207 |
19924374
|
For the in vitro studies, human retinal capillary endothelial cells (HRCECs) were cultured in the presence of varying glucose concentrations, and the expression of mRNA and protein for GRP78, ATF4, CHOP, and VEGF was assessed.
|
208 |
19924374
|
Expression of VEGF and CHOP mRNA levels were significantly increased in diabetic rats compared to control rats at 1, 3, and 6 months (P < 0.05).
|
209 |
19924374
|
However, GRP78 and ATF4 expression levels were unchanged.
|
210 |
19924374
|
Our findings suggest that early progression of DR may be mediated by ER stress, but probably does not involve changes in ATF4 or GRP78.

Transfection of hCOX-2, as well as of deletion and mutation promoter constructs, revealed that the CCAAT/enhancer-binding protein (C/EBP) and activator protein-1 (AP-1) predominantly contributed to the effects of CDCQ.
|
212 |
19931518
|
In addition, electrophoretic mobility shift assays and transfection results showed that CDCQ directly inhibited PMA-induced C/EBP and AP-1 transcription and binding activity.
|
213 |
19931518
|
CDCQ also remarkably reduced PMA-induced C/EBPbeta and c-jun protein expression.
|
214 |
19931518

Furthermore, CDCQ significantly inhibited PMA-induced activation of the mitogen-activated protein kinases (MAP kinases), JNK and p38.

Exendin-4 enhanced beta-cell proliferation and neogenesis in STZ-treated and -untreated Px rats and reduced beta-cell apoptosis partly by attenuating the expression of endoplasmic reticulum stress-response genes such as X-box-binding protein-1, activating transcription factor (ATF)-4, ATF6, and C/EBP-homologous protein.

UPR-mediated TRIB3 expression correlates with reduced AKT phosphorylation and inability of interleukin 6 to overcome palmitate-induced apoptosis in RINm5F cells.
|
222 |
20488947
|
In the present study, we have demonstrated that PA selectively disrupts IL6-induced RAC-alpha serine/threonine-protein kinase (AKT) activation without interfering with signal transducer and activator of transcription 3 phosphorylation in RINm5F cells.
|
223 |
20488947
|
The inability of IL6 to activate AKT in the presence of PA correlated with an inefficient protection against PA-induced apoptosis.
|
224 |
20488947
|
In addition, we have demonstrated that IL6 is unable to overcome PA-stimulated UPR, as assessed by activating transcription factor 4 (ATF4) and C/EBP homologous protein (CHOP) expression, X-box binding protein-1 gene mRNA splicing, and pancreatic eukaryotic initiation factor-2 alpha kinase phosphorylation, whereas no significant induction of UPR by pro-inflammatory cytokines was detected.
|
225 |
20488947
|
This unconditional stimulation of UPR and apoptosis by PA was accompanied by the stimulation of CHOP and tribble3 (TRIB3) expression, irrespective of the presence of IL6.
|
226 |
20488947
|
In this way, CHOP and ATF4 might mediate PA-induced TRIB3 expression and, by extension, the suppression of IL6 activation of pro-survival kinase AKT.

Palmitic acid induces podocyte ER stress, leading to an unfolded protein response as reflected by the induction of the ER chaperone immunoglobulin heavy chain binding protein (BiP) and proapoptotic C/EBP homologous protein (CHOP) transcription factor.

|
The mRNA levels of peroxidase proliferator-activated receptor (PPAR) γ and CCAAT/enhancer-binding protein α (C/EBPα), but not CCAAT/enhancer-binding protein ((C/EBP) β and δ, were reduced by UVA.
|
229 |
20693579
|
Moreover, the mRNA levels of PPAR γ target genes (lipoprotein lipase (LPL), CD36, adipocyte protein (aP2), and liver X receptor α (LXR)) were down-regulated by UVA.
|
230 |
20693579
|
Additionally, attempts to elucidate a possible mechanism underlying the UVA-mediated effects revealed that UVA induced migration inhibitory factor (MIF) gene expression, and this was mediated through activation of AP-1 (especially JNK and p42/44 MAPK) and nuclear factor-κB.
|
231 |
20693579
|
AMP-activated protein kinase phosphorylation and up-regulation of Kruppel-like factor 2 (KLF2) were induced by UVA.
|
232 |
20693579
|
Taken together, these findings suggest that the inhibition of adipogenic differentiation of human adipose tissue-derived mesenchymal stem cells by UVA occurs primarily through the reduced expression of PPAR γ, which is mediated by up-regulation of KLF2 via the activation of MIF-AMP-activated protein kinase signaling.
|

Akt and the transcription factor CCAAT enhancer-binding protein (C/EBP) mediated the genesis of these changes.

In type 2 diabetes, stimulation of insulin secretion by glucagon-like peptide-1 (GLP-1) has been found to be reduced, and the results of recent studies have shown that the expression of the GLP-1 receptor (GLP-1R) is reduced by chronic hyperglycemia.
|
235 |
21945929
|
In this study, we hypothesized that intermittent high glucose (IHG) conditions also reduced GLP-1-mediated cellular signaling via reduction in GLP-1R expression.
|
236 |
21945929
|
In comparison to both the SHG and control groups, IHG conditions induced a more significant impairment of insulin release and calcium influx in response to 1nM GLP-1 treatment.
|
237 |
21945929
|
In addition, the activity of caspase 3/7 as well as the gene expression of binding protein (Bip) and C/EBP homologous protein (CHOP), molecular markers of ER stress, was significantly higher in IHG-treated cells than in SHG-treated cells.
|
238 |
21945929
|
Interestingly, the expression level of GLP-1R was significantly lower under IHG conditions than under SHG conditions.
|
239 |
21945929
|
Collectively, these findings indicated that glucose fluctuation reduces GLP-1R expression through ER stress more profoundly than sustained hyperglycemia, which may contribute to the diminished response of GLP-1.

In vitro, treatment of adipocytes with rosiglitazone, an insulin sensitizer that binds to peroxisome proliferator-activated receptor (PPAR) receptors and increases the adipocyte response to insulin, significantly increased the expression of the antidiabetic adipokine adiponectin.

In terms of the mechanism underlying this action, regulatory regions of the PPARγ, ADIPOQ, and C/EBP contain the Stat5 DNA-binding sequences and were demonstrated, by gel shift experiments in vitro.

The adapter molecule CIKS (connection to IKK and SAPK/JNK; also known as Act1 or TRAF3IP2) is an upstream regulator of NF-κB and AP-1, and plays a role in inflammation and injury.

243 |
23085260
|
In EC, HG induced CIKS mRNA and protein expression via DPI-inhibitable Nox4-dependent ROS generation.
|
244 |
23085260
|
Further, HG induced CIKS transcription and enhanced CIKS promoter-dependent reporter gene activation via Nox4, ROS, AP-1 and C/EBP.
|
245 |
23085260
|
Coimmunoprecipitation and immunoblotting revealed CIKS/IKKβ/JNK physical association under basal conditions that was enhanced by HG treatment.
|
246 |
23085260
|
Importantly, CIKS knockdown inhibited HG-induced (i) IKKβ and JNK phosphorylation, (ii) p65 and c-Jun nuclear translocation, and (iii) NF-κB- and AP-1-dependent proinflammatory cytokine, chemokine, and adhesion molecule expression.
|
247 |
23085260
|
Notably, aortas from streptozotocin-induced and the autoimmune type 1 diabetic NOD and Akita mice showed enhanced DPI-inhibitable ROS generation and CIKS expression.
