No longer viewed as inert packets of energy, fat cells are two-faced masterminds of metabolism. Kendall Powell weighs up the differences between 'fat' fat cells and thin ones. 
Obesity and inflammation: the effects of weight loss
TLDR
The overall finding from the present review is that weight loss does improve inflammation in terms of both the inflammatory (C-reactive protein, TNF-α, IL-6 and leptin) and anti-inflammatory (adiponectin) ORIM. Expand
Whole‐body adipose tissue and lean muscle volumes and their distribution across gender and age: MR‐derived normative values in a normal‐weight Swiss population
To determine age‐ and gender‐dependent whole‐body adipose tissue and muscle volumes in healthy Swiss volunteers in Dixon MRI in comparison with anthropometric and bioelectrical impedance (BIA)Expand
Basic nutritional investigation Pan-PPAR agonist beneficial effects in overweight mice fed a high-fat high-sucrose diet
TLDR
Activation of PPAR- ,- , and - together is better than the activation of PPar- or - alone, because bezafibrate showed a wider range of action on metabolic, morphologic, and biometric alterations due to an HFHS diet in mice. Expand
Pan-PPAR agonist beneficial effects in overweight mice fed a high-fat high-sucrose diet.
TLDR
Activation of PPar-alpha, -delta, and -gamma together is better than the activation of PPAR-alpha or -gammas alone, because bezafibrate showed a wider range of action on metabolic, morphologic, and biometric alterations due to an HFHS diet in mice. Expand
disease The enigma of glucose and cardiovascular
TLDR
European prospective investigation intocancer in Norfolk (EPICeNORFOLK) study finds strong epidemiological evidence that diabetes is a major risk factor for cardiovascular disease (CVD) and despite advances in the treatment, outcomes in patients with diabetes Mellitus remain suboptimal. Expand
Inflammatory lipid mediators in adipocyte function and obesity
TLDR
It is speculated that lipid mediators act on important immune receptors to induce low-grade tissue inflammation, which leads to adipocyte and metabolic dysfunction. Expand
Complications and Comorbidities of Obesity
TLDR
The relationship between body weight and mortality: a quantitative analysis of combined information from existing studies and the chronic inflammatory hypothesis for the morbidity associated with morbid obesity: implications and effects of weight loss are analyzed. Expand
Under the Surface of Subcutaneous Adipose Tissue Biology.
TLDR
Therapeutic manipulations to preserve and enhance healthier fat in order to correct obesity-related metabolic disorders seem to be a relevant but still unexplored opportunity. Expand
Considerations on pig models for appetite, metabolic syndrome and obese type 2 diabetes: From food intake to metabolic disease.
TLDR
To accelerate the induction of obese type 2 diabetes, obese pigs can be titrated with streptozotocin, a chemical agent which selectively damages the insulin-producing pancreatic beta-cells, to lead to a stable hyperglycaemic, non-ketotic obese pig model which remains anabolic with time without the necessity of exogenous insulin treatment. Expand
Comparison of serum metabolite compositions between obese and lean growing pigs using an NMR-based metabonomic approach.
TLDR
It is indicated that obese pigs have distinct metabolism, including lipogenesis, lipid oxidation, energy utilization and partition, protein and amino acid metabolism, and fermentation of gastrointestinal microbes, compared with lean pigs. Expand

Adipose expression of tumor necrosis factor-alpha: direct role in obesity-linked insulin resistance.
TLDR
A role for TNF-alpha in obesity and particularly in the insulin resistance and diabetes that often accompany obesity is indicated. Expand
Obesity is associated with macrophage accumulation in adipose tissue.
TLDR
Transcript expression in perigonadal adipose tissue from groups of mice in which adiposity varied due to sex, diet, and the obesity-related mutations agouti (Ay) and obese (Lepob) found that the expression of 1,304 transcripts correlated significantly with body mass. Expand
Endoplasmic Reticulum Stress Links Obesity, Insulin Action, and Type 2 Diabetes
TLDR
It is shown that obesity causes endoplasmic reticulum (ER) stress, which leads to suppression of insulin receptor signaling through hyperactivation of c-Jun N-terminal kinase (JNK) and subsequent serine phosphorylation of insulin receptors substrate–1 (IRS-1). Expand
Mice Lacking Adiponectin Show Decreased Hepatic Insulin Sensitivity and Reduced Responsiveness to Peroxisome Proliferator-activated Receptor γ Agonists*
TLDR
Adiponectin is an important contributor to PPARγ-mediated improvements in glucose tolerance through mechanisms that involve the activation of the AMPK pathway. Expand
Acquirement of Brown Fat Cell Features by Human White Adipocytes*
TLDR
It is shown that PGC-1α is able to direct human WAT PPARγ toward a transcriptional program linked to energy dissipation, and that Alteration of energy balance through an increased utilization of fat in WAT may be a conceivable strategy for the treatment of obesity. Expand
Chemical Chaperones Reduce ER Stress and Restore Glucose Homeostasis in a Mouse Model of Type 2 Diabetes
TLDR
It is demonstrated that chemical chaperones enhance the adaptive capacity of the ER and act as potent antidiabetic modalities with potential application in the treatment of type 2 diabetes. Expand
Intention to Lose Weight, Weight Changes, and 18-y Mortality in Overweight Individuals without Co-Morbidities
TLDR
Deliberate weight loss in overweight individuals without known co-morbidities may be hazardous in the long term, and the health effects of weight loss are complex, possibly composed of oppositely acting processes. Expand
Retinol-binding protein 4 and insulin resistance in lean, obese, and diabetic subjects.
TLDR
RBP4 is an adipocyte-secreted molecule that is elevated in the serum before the development of frank diabetes and appears to identify insulin resistance and associated cardiovascular risk factors in subjects with varied clinical presentations, providing a rationale for antidiabetic therapies aimed at lowering serum RBP4 levels. Expand
Adipose-selective targeting of the GLUT4 gene impairs insulin action in muscle and liver
TLDR
Downregulation of GLUT4 and glucose transport selectively in adipose tissue can cause insulin resistance and thereby increase the risk of developing diabetes, as well as developing glucose intolerance and hyperinsulinaemia. Expand
Serum retinol binding protein 4 contributes to insulin resistance in obesity and type 2 diabetes
TLDR
It is shown that expression of retinol binding protein-4 (RBP4) is elevated in adipose tissue of adipose-Glut4-/- mice and RBP4 is an adipocyte-derived ‘signal’ that may contribute to the pathogenesis of type 2 diabetes. Expand
