156 15725703 To investigate the role of transcriptional factors, which are involved in adipocytes differentiation and adiposity, we have generated peroxisome proliferator-activated receptor (PPAR) gamma or CREB-binding protein (CBP)-deficient mice by gene targeting.
157 15725703 Heterozygous PPARgamma-deficient mice were protected from the development of insulin resistance due to adipocyte hypertrophy under a high-fat diet.
158 15725703 Heterozygous CBP-deficient mice showed increased insulin sensitivity and were completely protected from body weight gain induced by a high-fat diet.
159 15725703 PPARgamma or CBP deficiency results in increased effects of hormones such as adiponectin and leptin.
160 15725703 Adiponectin was decreased in obesity and lipoatrophy, and replenishment of adiponectin ameliorated insulin resistance.

162 15725703 Finally, cDNA encoding adiponectin receptors (AdipoR1/R2) have been identified by expression cloning.
163 15725703 The expression of AdipoR1/R2 appears to be inversely regulated by insulin in physiological and pathophysiological states such as fasting/refeeding, insulin deficiency, and hyperinsulinemia models, and it is correlated with adiponectin sensitivity.

173 15769985 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.
174 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.
175 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).
176 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.
177 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.
178 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.
179 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.
180 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.

189 15855314 Adenovirus-mediated adiponectin expression augments skeletal muscle insulin sensitivity in male Wistar rats.
190 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).
191 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.
192 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.
193 15855314 These results indicate that chronic adiponectin treatment enhances insulin sensitivity and could serve as a therapy for human insulin resistance.

212 15979609 Adiponectin receptor 2 expression in liver and insulin resistance in db/db mice given a beta3-adrenoceptor agonist.
213 15979609 Our aim was to determine the effect of a beta3-adrenoceptor agonist on plasma adiponectin levels and on the level of expression of mRNA for adiponectin, adiponectin receptor 1, and adiponectin receptor 2 in db/db mice.
214 15979609 Two weeks' oral administration of CL-316,243 led to decreased plasma levels of hemoglobin A1c, glucose, insulin, triglyceride and free fatty acid, and to an increased plasma adiponectin levels.
215 15979609 These results suggest that the increased plasma adiponectin levels seen in db/db mice treated with this beta3-adrenoceptor agonist induce a down-regulation of adiponectin receptor 2 mRNA expression specifically in the liver.

278 16634986 Adiponectin antagonizes many effects of tumour necrosis factor-alpha(TNF-alpha) and this, in turn, suppresses adiponectin production.
279 16634986 Furthermore, adiponectin secretion from adipocytes is enhanced by thiazolidinediones (which also act to antagonize TNF-alpha effects).
280 16634986 Thus, adiponectin may be the common mechanism by which TNF-alpha promotes, and the thiazolidinediones suppress, insulin resistance and inflammation.
281 16634986 Two adiponectin receptors, termed AdipoR1 and AdipoR2, have been identified and these are ubiquitously expressed.

283 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.

290 16724230 Association of sequence variations in the gene encoding adiponectin receptor 1 (ADIPOR1) with body size and insulin levels.
291 16731794 Recently, two types of adiponectin receptors (AdipoR1 and AdipoR2) were identified.
292 16731794 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.
293 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.
294 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.
295 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.
296 16731794 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.
297 16731794 These findings suggest that chronic exercise training affects the expression level of adiponectin receptors thereby improving insulin resistance in KKAy mice.

314 16823476 Adiponectin and adiponectin receptors in insulin resistance, diabetes, and the metabolic syndrome.
315 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.
316 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.
317 16823476 Upregulation of adiponectin is a partial cause of the insulin-sensitizing and antidiabetic actions of thiazolidinediones.
318 16823476 Therefore, adiponectin and adiponectin receptors represent potential versatile therapeutic targets to combat obesity-linked diseases characterized by insulin resistance.
319 16823476 This Review describes the pathophysiology of adiponectin and adiponectin receptors in insulin resistance, diabetes, and the metabolic syndrome.
320 17002473 Dietary conjugated linoleic acid lowered tumor necrosis factor-alpha content and altered expression of genes related to lipid metabolism and insulin sensitivity in the skeletal muscle of Zucker rats.
321 17002473 Additionally, expression of genes-related insulin sensitivity, such as adiponectin receptor 1, was significantly enhanced, and mRNA level of peroxisome proliferator activated receptor-alpha, known as a transcriptional factor related lipid metabolism and insulin signaling in skeletal muscle, was markedly increased in CLA-fed rats.

323 17002473 We suppose that the attenuated TNF-alpha accumulation in skeletal muscle may contribute to the alteration of expression of several genes and the alleviation of insulin resistance in CLA-fed Zucker rats.

451 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.
452 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.

647 19120283 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).
648 19120283 Its actions are mediated by two receptors, adiponectin receptors 1 (ADIPOR1) and 2 (ADIPOR2).
649 19136982 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.
650 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.
651 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.
652 19262030 Adiponectin is an adipokine that is specifically expressed in adipose tissues, directly sensitizes the body to insulin via specific receptors and its decreased plasma concentration is responsible for insulin resistance in obese humans.
653 19262030 In the present study, We obtained cDNA clones corresponding to feline adiponectin and adiponectin receptor 1 (AD-R1), whose nucleotide and deduced amino acid sequences were highly identical to those of other species, especially, the extra-cellular domain of feline AD-R1 was almost identical to that of human AD-R1.
654 19262030 These results suggest that adiponectin may be responsible for insulin function also in the cat, and it can be a target molecule for treatment of obesity and diabetes in cats.
655 19520781 The hormone adiponectin has been shown to be important in maintaining insulin sensitivity throughout the body, whereas potential effects on the placenta have not been assessed.
656 19520781 Adiponectin's role in regulating peripheral insulin responsiveness suggests it may be a factor in maintaining this balance during gestation as well.
657 19520781 Examination of human cytotrophoblast cells revealed that mRNA for both adiponectin receptors, adipoR1 and adipoR2, are abundantly expressed at term.
658 19520781 Treatment of cytotrophoblasts with adiponectin resulted in a significant drop, as assessed by quantitative RT-PCR, in expression for a number of genes involved in the endocrine function of the placenta, including the chorionic gonadotropin subunits, placental lactogen, and some steroidogenic enzymes.

665 19651784 C1q tumor necrosis factor alpha-related protein isoform 5 is increased in mitochondrial DNA-depleted myocytes and activates AMP-activated protein kinase.
666 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.
667 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.
668 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.
669 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.
670 19651784 These results highlight C1QTNF5 as a putative biomarker for mitochondrial dysfunction and a potent activator of AMPK.

697 20444885 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.
698 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.

729 21586697 The present study determined the dynamic change of adiponectin (APN, a cardioprotective adipokine), its receptor expression, and their impact upon myocardial ischemia/reperfusion (MI/R) injury during type 1 diabetes mellitus (T1DM) progression, and involved underlying mechanisms.

818 23568554 The transcription factor cAMP responsive element-binding protein (CREB) and activating transcription factors (ATFs) are downstream components of the insulin/IGF cascade, playing crucial roles in maintaining cell viability and embryo survival.
819 23568554 One of the CREB target genes is adiponectin, which acts synergistically with insulin.
820 23568554 We have studied the CREB-ATF-adiponectin network in rabbit preimplantation development in vivo and in vitro.
821 23568554 From the blastocyst stage onwards, CREB and ATF1, ATF3, and ATF4 are present with increasing expression for CREB, ATF1, and ATF3 during gastrulation and with a dominant expression in the embryoblast (EB).
822 23568554 In vitro stimulation with insulin and IGF-I reduced CREB and ATF1 transcripts by approximately 50%, whereas CREB phosphorylation was increased.
823 23568554 Activation of CREB was accompanied by subsequent reduction in adiponectin and adiponectin receptor (adipoR)1 expression.
824 23568554 Analysis of embryonic adipoRs showed an increased expression of adipoR1 and no changes in adipoR2 transcription.
825 23568554 We conclude that the transcription factors CREB and ATFs vitally participate in embryo-maternal cross talk before implantation in a cell lineage-specific manner.
826 23568554 Embryonic CREB/ATFs act as insulin/IGF sensors.
827 23568554 Lack of insulin is compensated by a CREB-mediated adiponectin expression, which may maintain glucose uptake in blastocysts grown in diabetic mothers.
828 23576026 In this study, newborn rats received daily injection of a pegylated rat leptin antagonist (pRLA) or saline from day 2 (d2) to d13 and then body weight gain, insulin/leptin sensitivity, and expression profile of microRNAs (miRNAs) at the hypothalamic level were determined at d28, d90, or d153 (following 1 month of high-fat diet (HFD) challenge).
829 23576026 We show that pRLA treatment predisposes rats to overweight and promotes leptin/insulin resistance in both hypothalamus and liver at adulthood. pRLA treatment also modifies the hypothalamic miRNA expression profile at d28 leading to the upregulation of 34 miRNAs and the downregulation of four miRNAs.
830 23576026 In pRLA rat muscle, Ucp2/3 and Adipor1/r2 are upregulated at d90.
831 23576026 In conclusion, we demonstrate that the impairment of leptin action in early life promotes insulin/leptin resistance and modifies the hypothalamic miRNA expression pattern in adulthood, and finally, this study highlights the potential link between hypothalamic miRNA expression pattern and insulin/leptin responsiveness.

848 23747931 N-Acetylcysteine and allopurinol up-regulated the Jak/STAT3 and PI3K/Akt pathways via adiponectin and attenuated myocardial postischemic injury in diabetes.
849 23747931 We postulated that NAC and ALP attenuated diabetic MI/R injury by up-regulating phosphatidylinositol 3-kinase/Akt (PI3K/Akt) and Janus kinase 2/signal transducer and activator of transcription-3 (JAK2/STAT3) pathways subsequent to adiponectin (APN) activation.
850 23747931 D rats displayed larger infarct size accompanied by decreased phosphorylation of Akt, STAT3 and decreased cardiac nitric oxide (NO) and APN levels.
851 23747931 NAC and ALP decreased MI/R injury in D rats, enhanced phosphorylation of Akt and STAT3, and increased NO and APN.
852 23747931 High glucose and hypoxia/reoxygenation exposure induced cell death and Akt and STAT3 inactivation in cultured cardiomyocytes, which were prevented by NAC and ALP.
853 23747931 The PI3K inhibitor wortmannin and Jak2 inhibitor AG490 abolished the protection of NAC and ALP.
854 23747931 Similarly, APN restored posthypoxic Akt and STAT3 activation and decreased cell death in cardiomyocytes.
855 23747931 Gene silencing with AdipoR2 siRNA or STAT3 siRNA but not AdipoR1 siRNA abolished the protection of NAC and ALP.
856 23747931 In conclusion, NAC and ALP prevented diabetic MI/R injury through PI3K/Akt and Jak2/STAT3 and cardiac APN may serve as a mediator via AdipoR2 in this process.
