Insulin resistance and obesity are both associated with lower plasma adiponectin concentrations. Since insulin resistance and obesity are related, the extent to which the association of adiponectin with insulin resistance is dependent on its relationship with obesity is unclear. To address this issue, fasting plasma adiponectin concentrations were measured in 60 nondiabetic subjects, stratified into four equal groups on the basis of both their degree of adiposity and insulin resistance. Insulin resistance was quantified by determining the steady-state plasma glucose (SSPG) concentration in response to an infusion of octreotide, glucose, and insulin, and degree of adiposity was assessed by BMI. Subjects were defined as obese (BMI ≥30.0 kg/m 2 ) or nonobese ( 2 ) and as either insulin sensitive (SSPG 190 mg/dl). Insulin-resistant subjects had significantly ( P

Plasma adiponectin concentrations were measured before and after moderate weight loss in 20 obese women, divided at baseline into insulin-resistant (IR) and insulin-sensitive (IS) subgroups on the basis of their steady-state plasma glucose (SSPG) concentration at the end of a 180-minute infusion of octreotide, glucose, and insulin. The groups were similar in age and body weight and lost comparable amounts of weight (8 to 9 kg) during the weight loss period. Fasting plasma insulin and SSPG concen...

Corrigendum (2004) Adiponectin (also known as 30-kDa adipocyte complement-related protein; Acrp30)1,2,3,4 is a hormone secreted by adipocytes that acts as an antidiabetic5,6,7,8,9,10,11,12 and anti-atherogenic8,12,13 adipokine. Levels of adiponectin in the blood are decreased under conditions of obesity, insulin resistance and type 2 diabetes2. Administration of adiponectin causes glucose-lowering effects and ameliorates insulin resistance in mice5,6,7. Conversely, adiponectin-deficient mice exh...

In animals, the adipocyte-derived hormone adiponectin has been shown to improve insulin sensitivity, a key factor in the pathogenesis of type 2 diabetes. In Pima Indians, high plasma adiponectin levels are associated with increased insulin sensitivity and reduced risk of type 2 diabetes. It is unclear whether this is also the case in white individuals and whether an additional beneficial effect on lipid metabolism exists. We therefore analyzed in nondiabetic individuals the associations between ...

Recently, it has been shown that adiponectin is an important insulin-sensitizing fat-derived protein which is downregulated in insulin resistance and obesity, and replenishment of which improves insulin sensitivity. In contrast, interleukin (IL)-6 appears as an adipocytokine serum concentrations of which are elevated in these states. However, it has not been determined whether IL-6 might impact on expression and secretion of adiponectin. To clarify this, 3T3-L1 adipocytes were treated with diffe...

Recent evidence suggests a role for adipose derived cytokines (adipocytokines) such as tumor necrosis factor-α (TNF-α), IL-6, and the recently discovered adiponectin in the mechanism of impaired glucose regulation and atherosclerosis in adults. However, the relationship between adipocytokines and body composition, fasting insulin, and fitness is virtually unknown children. Fasting blood sampling was performed in 30 healthy, predominately Hispanic- and Asian-American children (16 boys, mean age 1...

Background— Plasma C-reactive protein (CRP) concentrations are increased in obese and/or hyperinsulinemic individuals. The goal of this study was to determine if the relation between insulin resistance and CRP was independent of obesity. Methods and Results— Plasma CRP concentrations were measured before and after 3 months of calorie restriction in 38 healthy, obese women. Steady-state plasma glucose (SSPG) concentration during a 180-minute infusion of octreotide, glucose, and insulin was used t...

Adiponectin is an adipocyte-derived plasma protein with insulin-sensitizing and antiatherosclerotic properties. Because adipose tissue depots differ in the strength of their association with the adverse metabolic consequences of obesity, we studied the secretion of adiponectin in vitro from paired samples of isolated human omental and sc adipocytes and its regulation by insulin and rosiglitazone. Cells were incubated for 12 or 24 h with and without treatment with 100 nm insulin, 8 μm rosiglitazo...

Insulin resistance and hyperinsulinemia are known atherosclerosis risk factors. The association between adiponectin plasma levels and obesity, insulinemia, and atherosclerosis has been shown. Thus, adiponectin may be a link between hyperinsulinemia and vascular disease. In vitro data demonstrated a reduction of adiponectin expression by insulin. However, it is still unclear whether insulin regulates adiponectinemia in vivo in humans. Five healthy male volunteers were studied. Circulating adipone...

The insulin-sensitizing effects of thiazolidinediones are thought to be mediated through peroxisome proliferator-activated receptor-γ, a nuclear receptor that is highly abundant in adipose tissue. It has been reported that adipocytes secrete a variety of proteins, including tumor necrosis factor-α, resistin, plasminogen activator inhibitor-1, and adiponectin. Adiponectin is a fat cell-secreted protein that has been reported to increase fat oxidation and improve insulin sensitivity. Our aim was t...

Exercise represents the most important integrative therapy in metabolic, immunologic and chronic diseases; it represents a valid strategy in the non-pharmacological intervention of lifestyle linked diseases. A large body of evidence indicates physical exercise as an effective measure against chronic non-communicable diseases. The worldwide general evidence for health benefits are both for all ages and skill levels. In a dysregulated lifestyle such as in the obesity, there is an imbalance in the ...

Abstract Adiponectin (ADP) is an adipokine secreted by adipose tissue with anti-inflammatory, antiatherogenic, and antidiabetic properties. In human serum, it is presented as three different forms: low molecular weight (LMW), medium molecular weight (MMW), and high molecular weight (HMW). High molecular weight isomer is the most active form of ADP and is more closely related with obesity-induced insulin resistance and metabolic syndrome than total ADP. Selective protease treatment can be used in...

Abstract Adiponectin is an adipokine that exerts insulin-sensitizing and antiinflammatory properties. The aim of this study was to develop and validate a new heterologous ultrasensitive assay based on amplified luminescent technology for adiponectin determination in serum and saliva of dogs. A complete analytical validation of the assay was made in these fluids, and also this assay was applied to quantify adiponectin in serum and saliva of obese and lean dogs and dogs with leishmaniosis. These c...

ABSTRACTIntroduction: In the human organism, a constant interplay exists between the stress system [which includes the activity of the hypothalamic-pituitary-adrenal (HPA) axis] and the adipose tissue. This interplay is mediated by hormones of the HPA axis such as corticotropin-releasing hormone (CRH), adrenocorticotropic hormone (ACTH) and glucocorticoids (GCs) and adipokines secreted by the adipose tissue.Areas covered: In this critical review, the bi-directional interactions between HPA axis ...

Background: Liver enzymes may be implicated in glucose homeostasis; liver enzymes progressively change during pregnancy but longitudinal data during pregnancy in relation to insulin resistance and gestational diabetes (GDM) risk are lacking. We investigated longitudinal associations of γ-glutamyl transferase (GGT) and alanine aminotransferase (ALT) with insulin secretion and resistance markers across early to mid-pregnancy and subsequent GDM risk. Methods: Within the prospective Pregnancy Enviro...

Previous studies revealed the potential significance of circulating adiponectin levels with respect to the diagnosis and prediction of metabolic syndrome, but uncertainty has been noted across different cohorts. Systematic evaluation was performed for diagnostic accuracy and predictivity of adiponectin variation for metabolic syndrome in enrolled studies including 1248 and 6020 subjects, respectively. Adiponectin can identify metabolic syndrome with moderate accuracy (area under the curve=0.81, ...

The level of fat deposition in carcass is a crucial factor influencing meat quality. Guangling Large-Tailed (GLT) and Small-Tailed Han (STH) sheep are important local Chinese fat-tailed breeds that show distinct patterns of fat depots. To gain a better understanding of fat deposition, transcriptome profiles were determined by RNA-sequencing of perirenal, subcutaneous, and tail fat tissues from both the sheep breeds. The common highly expressed genes (co-genes) in all the six tissues, and the gen...
