|
Conversely, adiponectin-deficient mice exhibit insulin resistance and diabetes.
|

12802337
|
This insulin-sensitizing effect of adiponectin seems to be mediated by an increase in fatty-acid oxidation through activation of AMP kinase and PPAR-alpha.

|
Here we report the cloning of complementary DNAs encoding adiponectin receptors 1 and 2 (AdipoR1 and AdipoR2) by expression cloning.

|
AdipoR1 is abundantly expressed in skeletal muscle, whereas AdipoR2 is predominantly expressed in the liver.
|
7 |
12802337
|
Expression of AdipoR1/R2 or suppression of AdipoR1/R2 expression by small-interfering RNA supports our conclusion that they serve as receptors for globular and full-length adiponectin, and that they mediate increased AMP kinase and PPAR-alpha ligand activities, as well as fatty-acid oxidation and glucose uptake by adiponectin.

MTII administration for 24 h prevents food deprivation-induced alterations in hypothalamic neuropeptide Y (NPY) and liver adiponectin receptor 1 and adiponectin receptor 2 mRNA expression, but does not alter hypothalamic mRNA expression of melanocortin 4 receptor or adiponectin serum and mRNA expression levels.
|
28 |
14693701
|
NPY and agouti gene-related protein (AgRP) mRNA expression after 8 days of MTII is increased to levels comparable to pair-fed mice.
|
29 |
14693701
|
In summary, 1) MTII is an effective treatment for obesity and related metabolic defects in leptin-resistant (DIO, UCP1-DTA) and leptin-sensitive (ob/ob) mouse models of obesity; 2) the effects of MTII on food intake and body weight are more pronounced in DIO mice than in lean mice; 3) the tachyphylactic effect after prolonged MTII administration appears to be, at least in part, caused by a compensatory upregulation of NPY and AgRP mRNA levels, whereas decreasing leptin levels may play a very minor role in mediating tachyphylaxis; and 4) alterations in adiponectin receptor mRNA expression after fasting or MTII treatment may contribute to altered insulin sensitivity and needs to be studied further.

Adiponectin plays a crucial role in the association between obesity, type 2 diabetes, and insulin resistance.
|
31 |

Mechanisms explaining the relationship between adiponectin and insulin resistance suggest that adiponectin and tumor necrosis factor (TNF)-alpha inhibited each other's expression and production in adipocytes.
|
32 |
15149866

Adiponectin receptor 1 gene (ADIPOR1) as a candidate for type 2 diabetes and insulin resistance.
|
59 |
15277397

Considerable data support adiponectin as an important adipose-derived insulin sensitizer that enhances fatty acid oxidation and alters hepatic gluconeogenesis.
|
60 |
15277397
|
Adiponectin acts by way of two receptors, ADIPOR1 and ADIPOR2.
|
61 |
15277397
|
ADIPOR1 is widely expressed in tissues, including muscle, liver, and pancreas, and binds the globular form of adiponectin with high affinity.
|
62 |
15331527
|
The adiponectin receptors, AdipoR1 and AdipoR2, are thought to transmit the insulin-sensitizing, anti-inflammatory, and atheroprotective effects of adiponectin.
|
63 |
15331527
|
Myotubes from 40 metabolically characterized donors expressed 1.8-fold more AdipoR1 than AdipoR2 mRNA (588 +/- 35 vs. 321 +/- 39 fg/microg total RNA).
|
64 |
15331527
|
AdipoR1 mRNA expression was positively correlated with in vivo insulin and C-peptide concentrations, first-phase insulin secretion, and plasma triglyceride and cholesterol concentrations before and after adjustment for sex, age, waist-to-hip ratio, and body fat.
|
65 |
15331527
|
In multivariate linear regression models, mRNA expression of AdipoR1, but not AdipoR2, was a determinant of first-phase insulin secretion independent of insulin sensitivity and body fat.

The following two adiponectin receptor types were recently identified: AdipoR1 is abundantly expressed in muscle, whereas AdipoR2 is predominantly expressed in the liver.
|
87 |
15613685
|
To clarify the regulation of adiponectin receptor gene expression in diabetic states, we examined mRNA levels of AdipoR1 in the muscles of diabetic animals by Northern blotting.
|
88 |
15613685
|
The level of AdipoR1 mRNA was increased approximately 2.5-fold in muscle of streptozotocin (STZ) diabetic mice, but the normal level was restored by insulin administration, indicating that insulin has an inhibitory effect on AdipoR1 expression.
|
89 |
15613685
|
Insulin treatment for 24 h decreased AdipoR1 expression by approximately 60% in C2C12 cells.
|
90 |
15613685
|
AdipoR1 expression in insulin-resistant diabetic mice was also investigated.
|
91 |
15613685
|
Our results indicate that regulation of AdipoR1, but not that of AdipoR2, may be involved in glucose and lipid metabolism in diabetic states.

In rodent skeletal muscle, globular adiponectin (gAD) activates AMP-kinase (AMPK) and stimulates fatty acid oxidation effects mediated through the adiponectin receptors, AdipoR1 and AdipoR2.
|
99 |
15769985
|
In the present study, we examined the mRNA expression of adiponectin receptors and the effects of gAD on AMPK activity and fatty acid oxidation in skeletal muscle myotubes from lean, obese, and obese type 2 diabetic subjects.
|
100 |
15769985
|
Myotubes from all groups expressed approximately 4.5-fold more AdipoR1 mRNA than AdipoR2, and obese subjects tended to have higher AdipoR1 expression (P = 0.052).
|
101 |
15769985
|
In lean myotubes, gAD activates AMPKalpha1 and -alpha2 by increasing Thr172 phosphorylation, an effect associated with increased acetyl-coenzyme A carboxylase (ACCbeta) Ser221 phosphorylation and enhanced rates of fatty acid oxidation, effects similar to those observed after pharmacological AMPK activation by 5-aminoimidazole-4-carboxamide riboside.
|
102 |
15769985
|
In obese myotubes, the activation of AMPK signaling by gAD at low concentrations (0.1 mug/ml) was blunted, but higher concentrations (0.5 mug/ml) stimulated AMPKalpha1 and -alpha2 activities, AMPK and ACCbeta phosphorylation, and fatty acid oxidation.
|
103 |
15769985
|
In obese type 2 diabetic myotubes, high concentrations of gAD stimulated AMPKalpha1 activity and AMPK phosphorylation; however, ACCbeta phosphorylation and fatty acid oxidation were unaffected.
|
104 |
15769985
|
Reduced activation of AMPK signaling and fatty acid oxidation in obese and obese diabetic myotubes was not associated with reduced protein expression of AMPKalpha and ACCbeta or the expression and activity of the upstream AMPK kinase, LKB1.
|
105 |
15769985
|
These data suggest that reduced activation of AMPK by gAD in obese and obese type 2 diabetic subjects is not caused by reduced adiponectin receptor expression but that aspects downstream of the receptor may inhibit AMPK signaling.

Adenovirus-mediated adiponectin expression augments skeletal muscle insulin sensitivity in male Wistar rats.
|
115 |
15855314
|
In this study, we investigated the chronic in vivo effect of adiponectin on insulin sensitivity and glucose metabolism by overexpressing the adiponectin protein in male Wistar rats using intravenous administration of an adenovirus (Adv-Adipo).
|
116 |
15855314
|
In contrast, insulin's effect on the suppression of hepatic glucose output and plasma free fatty acid levels was not enhanced in Adv-Adipo rats compared with controls, suggesting that high levels of adiponectin expression in the liver may lead to a local desensitization.
|
117 |
15855314
|
One interesting finding was that in male Wistar rats, both AdipoR1 and AdipoR2 expression levels were higher in skeletal muscle than in liver, as it is the case in humans.
|
118 |
15855314
|
These results indicate that chronic adiponectin treatment enhances insulin sensitivity and could serve as a therapy for human insulin resistance.

|
120 |
15897298
|
Functional analyses including generation of adiponectin transgenic or knockout mice have revealed that adiponectin serves as an insulin-sensitizing adipokine.
|
121 |
15897298
|
In fact, obesity-linked down-regulation of adiponectin was a mechanism whereby obesity could cause insulin resistance and diabetes.
|
122 |
15897298
|
Recently, we have cloned adiponectin receptors in the skeletal muscle (AdipoR1) and liver (AdipoR2), which appear to comprise a novel cell-surface receptor family.
|
123 |
15897298
|
We showed that AdipoR1 and AdipoR2 serve as receptors for globular and full-length adiponectin and mediate increased AMP-activated protein kinase, peroxisome proliferator-activated receptor-alpha ligand activities, and glucose uptake and fatty-acid oxidation by adiponectin.
|
124 |
15897298
|
Obesity decreased expression levels of AdipoR1/R2, thereby reducing adiponectin sensitivity, which finally leads to insulin resistance, the so-called "vicious cycle."

Peroxisome proliferator-activated receptor (PPAR)alpha activation increases adiponectin receptors and reduces obesity-related inflammation in adipose tissue: comparison of activation of PPARalpha, PPARgamma, and their combination.
|
153 |
16306350
|
We examined the effects of activation of peroxisome proliferator-activated receptor (PPAR)alpha, PPARgamma, and both of them in combination in obese diabetic KKAy mice and investigated the mechanisms by which they improve insulin sensitivity.
|
154 |
16306350
|
PPARalpha activation by its agonist, Wy-14,643, as well as PPARgamma activation by its agonist, rosiglitazone, markedly improved insulin sensitivity.
|
155 |
16306350
|
Adipocyte size in Wy-14,643-treated KKAy mice was much smaller than that of vehicle- or rosiglitazone-treated mice, suggesting that activation of PPARalpha prevents adipocyte hypertrophy.
|
156 |
16306350
|
Importantly, Wy-14,643 treatment upregulated expression of the adiponectin receptor (AdipoR)-1 and AdipoR2 in WAT, which was decreased in WAT of KKAy mice compared with that in nondiabetic control mice.
|
157 |
16306350
|
These data suggest that PPARalpha activation prevents inflammation in WAT and that dual activation of PPARalpha and -gamma enhances the action of adiponectin by increasing both adiponectin and AdipoRs, which can result in the amelioration of obesity-induced insulin resistance.

Leptin gene expression has been investigated in term placental tissue complicated by gestational diabetes mellitus (GDM), but never in conjunction with all isoforms of the leptin receptor (LEPR A-D), or with adiponectin receptors (ADIPOR1 and 2).

We assessed placental gene expression of leptin, LEPR A-D and ADIPOR1 and 2 by real time PCR using mRNA from maternal and fetal biopsies.

No significant changes were seen in GDM cases compared with controls in LEPR A-D or ADIPOR1 and 2. mRNA derived from maternal-side tissue was positively correlated with tissue from the fetal side for all genes studied (all p<0.01).

Adiponectin antagonizes many effects of tumour necrosis factor-alpha(TNF-alpha) and this, in turn, suppresses adiponectin production.
|
191 |
16634986
|
Furthermore, adiponectin secretion from adipocytes is enhanced by thiazolidinediones (which also act to antagonize TNF-alpha effects).
|
192 |
16634986
|
Thus, adiponectin may be the common mechanism by which TNF-alpha promotes, and the thiazolidinediones suppress, insulin resistance and inflammation.

|
Two adiponectin receptors, termed AdipoR1 and AdipoR2, have been identified and these are ubiquitously expressed.

AdipoR1 is most highly expressed in skeletal muscle and has a prominent action to activate AMPK, and hence promote lipid oxidation.
|
195 |
16634986
|
AdipoR2 is most highly expressed in liver, where it enhances insulin sensitivity and reduces steatosis via activation of AMPK and increased peroxisome-proliferator-activated receptor alpha ligand activity.

Recently, two types of adiponectin receptors (AdipoR1 and AdipoR2) were identified.
|
203 |

Following the experimental protocol, an intravenous glucose tolerance test and an intraperitoneal insulin tolerance test were performed in addition to the measurement of blood lipid and adiponectin concentrations.
|
204 |
16731794
|
Both the 8-week exercise training and food restriction protocol improved insulin resistance in KKAy mice but did not alter plasma adiponectin concentration nor its mRNA expression.
|
205 |
16731794
|
In comparison with C57BL/6 mice, AdipoR1 expression level was significantly decreased in skeletal muscle and AdipoR2 expression level was significantly increased in the liver in KKAy mice.
|
206 |
16731794
|
After the 8-week experimental protocol, the expression level of AdipoR1 mRNA was approximately 1.8-fold greater in the skeletal muscle and 1.3-fold greater in the liver, and the level of AdipoR2 mRNA was 30% less in the liver of the ET group as compared with the control group.
|
207 |

|
In contrast, no significant changes were observed in the expression of genes encoding the adiponectin receptors in addition to other genes except for CPT1 in the DR group.

Adiponectin and adiponectin receptors in insulin resistance, diabetes, and the metabolic syndrome.

226 |
16823476
|
Hypoadiponectinemia, caused by interactions of genetic factors such as SNPs in the Adiponectin gene and environmental factors causing obesity, appears to play an important causal role in insulin resistance, type 2 diabetes, and the metabolic syndrome, which are linked to obesity.
|
227 |
16823476
|
The adiponectin receptors, AdipoR1 and AdipoR2, which mediate the antidiabetic metabolic actions of adiponectin, have been cloned and are downregulated in obesity-linked insulin resistance.
|
228 |
16823476
|
Upregulation of adiponectin is a partial cause of the insulin-sensitizing and antidiabetic actions of thiazolidinediones.

Therefore, adiponectin and adiponectin receptors represent potential versatile therapeutic targets to combat obesity-linked diseases characterized by insulin resistance.

Adiponectin has insulin-mimetic and -sensitizing actions including stimulation of glucose uptake in skeletal muscle and suppression of glucose production in liver.
|
232 |
17052201
|
Adiponectin acts via two receptor isoforms, AdipoR1 (adiponectin receptor 1) and AdipoR2, which have distinct tissue distributions and affinities for recognition of the various adiponectin forms.

Alternatively, targeted disruption of AdipoR1 resulted in the abrogation of adiponectin-induced AMPK activation, whereas that of AdipoR2 resulted in decreased activity of PPAR-alpha signaling pathways.
|
262 |
17268472
|
Simultaneous disruption of both AdipoR1 and R2 abolished adiponectin binding and actions, resulting in increased tissue triglyceride content, inflammation and oxidative stress, and thus leading to insulin resistance and marked glucose intolerance.
|
263 |
17268472
|
Therefore, AdipoR1 and R2 serve as the predominant receptors for adiponectin in vivo and play important roles in the regulation of glucose and lipid metabolism, inflammation and oxidative stress in vivo.

The decreased plasma adiponectin levels and renal protein expression of adiponectin receptor 1 were accompanied by the decreased renal phosphorylation of adenosine monophosphate (AMP)-activated protein kinase (AMPK)-alpha (Thr172) and protein expression of phospho-acetyl coenzyme A carboxylase (ACC) (Ser79) which led to the increased renal triglyceride levels in diabetic rats.
|
277 |
17270171
|
There was no difference in the protein expression of renal adiponectin receptor 2 between control and diabetic rats.
|
278 |
17270171
|
N-acetylcysteine treatment attenuated the increased oxidative stress, plasma and renal lipids, urine protein excretion rate, mesangial matrix expansion index, and protein expression of renal CTGF, but did not affect plasma adiponectin levels, renal protein expression of adiponectin receptor 1, phosphorylation of AMPK-alpha (Thr172) and renal protein expression of phospho-ACC (Ser79) in diabetic rats.
|
279 |
17270171
|
These results suggested that the decreased plasma adiponectin and renal adiponectin receptor 1 result in the increased renal triglyceride that stimulates renal CTGF expression leading to the renal hypertrophy and the deteriorated renal function in the diabetic rats.
|
280 |
17270171
|
N-acetylcysteine treatment attenuates the increased oxidative stress, but has no effect on the decreased plasma adiponectin and renal adiponectin receptor 1 in diabetic rats, indicating that oxidative stress may not contribute to the decreased plasma adiponectin and renal adiponectin receptor 1 protein expression in diabetic rats.

|
283 |

Globular adiponectin activates nuclear factor-kappaB and activating protein-1 and enhances angiotensin II-induced proliferation in cardiac fibroblasts.
|
291 |
17327451
|
Nuclear factor-kappaB (NF-kappaB) and activating protein-1 (AP-1) activation were examined using cardiac fibroblasts prepared from the ventricles of 1- to 2-day-old Wistar rats and grown in culture. gAd activated NF-kappaB and enhanced tumor necrosis factor-alpha (TNF-alpha)-induced NF-kappaB activity. gAd also activated AP-1 and enhanced angiotensin II (Ang II)-induced AP-1 activity. gAd induced mRNA expression of c-fos and c-jun and activated extracellular signal-regulated kinase.

TNF-alpha alters visfatin and adiponectin levels in human fat.
|
295 |
17447161
|
Adiponectin and visfatin are newly discovered adipokines that are strongly expressed in human visceral adipose tissue.
|
296 |
17447161
|
To identify new regulatory mechanisms in fat, the effect of TNF-alpha (TNF) on adiponectin, on its two receptors, and on visfatin was investigated by incubating human visceral adipose tissue from patients without diabetes mellitus with TNF for 24, 48 and 72 hours.
|
297 |
17447161
|
The mRNA expression of visfatin, adiponectin, and its two receptors, as well as the protein expression of adiponectin were determined.
|
298 |
17447161
|
A decrease of adiponectin mRNA expression of 97% after incubation with TNF (5.75 nmol/l) for 24 hours, a decrease of 91% after 48 hours, and a decrease of 96% after 72 hours were measured.
|
299 |
17447161
|
The mRNA level of adiponectin receptor 1 (AdipoR1) was elevated about 72% after 48 hours of incubation and 67% after 72 hours of incubation, whereas the mRNA expression of adiponectin receptor 2 (AdipoR2) was not altered significantly.
|
300 |
17447161
|
The visfatin mRNA level was found to be highly increased by 255% after 24 hours and 335% after 48 hours and 341% after 72 hours of incubation with TNF (5.75 nmol/l).
|
301 |
17447161
|
We demonstrate that TNF has regulatory functions on adiponectin, AdipoR1 and on visfatin in human visceral adipose tissue.
|
302 |
17447161
|
TNF levels are elevated in states of obesity and insulin resistance.
|
303 |
17447161
|
Due to this fact TNF could be the reason that there is a decrease in the level of adiponectin, whereas there is an increase in the level of visfatin in states of obesity and insulin resistance.

An adipokine that could potentially mediate this effect is adiponectin, and we demonstrated that small interfering RNA-mediated knockdown of adiponectin receptor-2 in muscle cells reduced the uptake of glucose upon coculture with primary rat adipocytes.
|
305 |
17569760
|
Coculture induced phosphorylation of AMP-activated protein kinase (T172) and interestingly also insulin receptor substrate-1 (Y612) and Akt (T308 & S473), which could be attenuated after adiponectin receptor-2-small interfering RNA treatment.

|
309 |

|
While, although physical exercise is useful for improving insulin sensitivity, the effect of physical exercise on adiponectin and adiponectin receptors are still unclear.
|
310 |
17647137
|
Following an acute exercise, plasma glucose, insulin, FFA, and adiponectin were measured.
|
311 |
17647137
|
Although acute exercise did not significantly change plasma adiponectin concentration at 2 hours or 18 hours after the exercise compared with control group, the expression levels of AdipoR1 significantly increased in both skeletal muscle (2H: 1.2-fold, p=0.0423, 18H: 1.4-fold, p=0.0006) and liver (2H: 1.3-fold, p=0.0448) compared with control group.
|
312 |
17647137
|
These findings suggest that acute exercise affects the expression level of adiponectin receptors, and an increase of Foxo1 expression might be relative to regulate adiponectin receptors.

|
324 |
17884446
|
The plasma adiponectin level was decreased, but the cardiac protein expression of adiponectin receptor 1 was increased in diabetic rats.
|
325 |
17884446
|
There was no difference in the cardiac adiponectin level and the cardiac adiponectin receptor 2 protein expression between control and diabetic rats.
|
326 |
17884446
|
The phosphorylation of AMPK-alpha and protein expression of GLUT4 were decreased, but the phosphorylation of ACC was unchanged in diabetic rat hearts.

327 |
17884446

Two adiponectin receptors were recently identified, AdipoR1 and R2.
|
330 |
18018580
|
AdipoR1 expression was increased approximately 2.5-fold in muscle tissues from insulin-deficient diabetic mice, but normalized with insulin administration.
|
331 |
18018580
|
AdipoR1 expression was decreased by 44% in insulin-resistant obese, as compared to lean, mice.
|
332 |
18018580
|
These results indicate AdipoR1 expression to correlate inversely with plasma insulin levels.
|
333 |
18018580
|
Insulin treatment for 24 h decreased AdipoR1 expression by approximately 60% in C2C12 myocytes.
|
334 |
18018580

Adiponectin, an adipocytokine with anti-inflammatory and insulin-sensitizing properties, may provide a mechanism by which insulin resistance accelerates autoimmunity in type 1 diabetes (T1D).
|

|
Its actions are mediated by two receptors, adiponectin receptors 1 (ADIPOR1) and 2 (ADIPOR2).

|
We have found that decreased high molecular weight (HMW) adiponectin plays a crucial and causal role in obesity-linked insulin resistance and metabolic syndrome; that AdipoR1 and AdipoR2 serve as the major AdipoRs in vivo; and that AdipoR1 activates the AMP kinase (AMPK) pathway and AdipoR2, the peroxisome proliferator-activated receptor alpha (PPARalpha) pathway in the liver, to increase insulin sensitivity and decrease inflammation.
|
398 |
19136982
|
Further conclusions are that decreased adiponectin action and increased monocyte chemoattractant protein-1 (MCP-1) form a vicious adipokine network causing obesity-linked insulin resistance and metabolic syndrome; PPARgamma upregulates HMW adiponectin and PPARalpha upregulates AdipoRs; that dietary osmotin can serve as a naturally occurring adiponectin receptor agonist; and finally, that under starvation conditions, MMW adiponectin activates AMPK in hypothalamus, and promotes food intake, and at the same time HMW adiponectin activates AMPK in peripheral tissues, such as skeletal muscle, and stimulates fatty-acids combustion.
|
399 |
19136982
|
Importantly, under pathophysiological conditions, such as obesity and diabetes, only HMW adiponectin was decreased; therefore, strategies to increase only HMW adiponectin may be a logical approach to provide a novel treatment modality for obesity-linked diseases, such as insulin resistance and type 2 diabetes.

C1q tumor necrosis factor alpha-related protein isoform 5 is increased in mitochondrial DNA-depleted myocytes and activates AMP-activated protein kinase.
|
415 |
19651784
|
Here we show that the expression of C1q tumor necrosis factor alpha-related protein isoform 5 (C1QTNF5) is drastically increased following depletion of mtDNA in myocytes.
|
416 |
19651784
|
C1QTNF5 is homologous to adiponectin in respect to domain structure, and its expression and secretion from myocytes correlated negatively with the cellular mtDNA content.
|
417 |
19651784
|
Similar to adiponectin, C1QTNF5 induced the phosphorylation of AMP-activated protein kinase (AMPK), leading to increased cell surface recruitment of GLUT4 and increased glucose uptake.
|
418 |
19651784
|
C1QTNF5-mediated phosphorylation of AMPK or acetyl-CoA carboxylase was unaffected by depletion of adiponectin receptors such as AdipoR1 or AdipoR2, which indicated that adiponectin receptors do not participate in C1QTNF5-induced activation of AMPK.
|
419 |
19651784
|
These results highlight C1QTNF5 as a putative biomarker for mitochondrial dysfunction and a potent activator of AMPK.

In colon cancer cells, adiponectin attenuated cell cycle progression at the G(1)/S boundary and concurrently increased expression of cyclin-dependent kinase inhibitors such as p21 and p27.
|
422 |
20444885
|
Adiponectin stimulated AMP-activated protein kinase (AMPK) phosphorylation whereas inhibition of AMPK activity blunted the effect of adiponectin on the proliferation of colon cancer cells.
|
423 |
20444885
|
Furthermore, knockdown of adiponectin receptors such as AdipoR1 and AdipoR2 relieved the suppressive effect of adiponectin on the growth of colon cancer cells.
|
424 |
20444885
|
In addition, adiponectin repressed the expression of sterol regulatory element binding protein-1c, which is a key lipogenic transcription factor associated with colon cancers.
|
425 |

|
These results suggest that adiponectin could inhibit the growth of colon cancer cells through stimulating AMPK activity.

The mRNA levels of the three adiponectin receptors, AdipoR1, AdipoR2, and T-cadherin, were highly interrelated (r ≥ 0.91).
|
433 |
21331343

The myocyte expression levels of AdipoR1 and T-cadherin were inversely associated with the donors' fasting plasma triglycerides (P < .03).

|
Dietary capsaicin markedly decreased fasting glucose/insulin and triglyceride levels in the plasma and/or liver, as well as expression of inflammatory adipocytokine genes (e.g., monocyte chemoattractant protein-1 and interleukin-6) and macrophage infiltration.
|
435 |
21332406
|
At the same time expression of the adiponectin gene/protein and its receptor, AdipoR2, increased in adipose tissue and/or plasma, accompanied by increased activation of hepatic AMP-activated protein kinase, a marker of fatty acid oxidation.

|
Adiponectin enhances insulin sensitivity by increasing hepatic IRS-2 expression via a macrophage-derived IL-6-dependent pathway.
|
437 |
21459325
|
Many actions of adiponectin, a well-recognized antidiabetic adipokine, are currently attributed to the activation of two critical molecules downstream of AdipoR1 and R2: AMP-activated kinase (AMPK) and peroxisome proliferator-activated receptor α (PPARα).
|
438 |
21459325
|
However, the direct effects of adiponectin on insulin signaling molecules remain poorly understood.
|
439 |
21459325
|
We show here that adiponectin upregulates IRS-2 through activation of signal transducer and activator of transcription-3 (STAT3).
|
440 |
21459325
|
Surprisingly, this activation is associated with IL-6 production from macrophages induced by adiponectin through NFκB activation independent of its authentic receptors, AdipoR1 and AdipoR2.
|
441 |
21459325
|
These data have unraveled an insulin-sensitizing action initiated by adiponectin leading to upregulation of hepatic IRS-2 via an IL-6 dependent pathway through a still unidentified adiponectin receptor.

|
Once some of the effects of adiponectin and its receptors were known, it was not long until an effort was made to find the associations between specific SNPs of the genes of this hormone and its receptors as genetic risk factors for insulin resistance, type 2 diabetes mellitus, and metabolic syndrome, although these genes were investigated as possible candidates related to the development of these metabolic disorders.
|
520 |
23656997
|
All of these inconsistencies lead to a review that summarizes the SNPs of the genes of adiponectin, AdipoR1, and AdipoR2 that are mostly related to insulin resistance syndrome, type 2 diabetes mellitus, and metabolic syndrome, although presenting the possible factors that should be taken into account to homogenize the results obtained until now.

|
Gene silencing with AdipoR2 siRNA or STAT3 siRNA but not AdipoR1 siRNA abolished the protection of NAC and ALP.
|
