Excess caloric intake does not always translate to an expansion of the subcutaneous adipose tissue (SAT) and increase in fat mass. It is now recognized that adipocyte type (white, WAT, or brown, BAT), size (large vs. small) and metabolism are important factors for the development of cardiometabolic diseases. When the subcutaneous adipose tissue is not able to expand in response to increased energy intake the excess substrate is stored as visceral adipose tissue or as ectopic fat in tissues as muscle, liver and pancreas...

OBJECTIVE: Epididymal adipose tissue (EAT), a visceral fat depot, is more closely associated with metabolic dysfunction than inguinal adipose tissue (IAT), a subcutaneous depot. This study evaluated whether the nuclear receptor RORα, which controls inflammatory processes, could be implicated. METHODS: EAT and IAT were compared in a RORα loss-of-function mouse (sg/sg) and in wild-type (WT) littermates, fed a standard diet (SD) or a Western diet (WD), to evaluate the impact of RORα expression on inflammatory status and on insulin sensitivity (IS) of each fat depot according to the diet...

BACKGROUND AND OBJECTIVE: The sequence of prenatal growth restraint and postnatal catch-up growth may lead to hepato-visceral adiposity, insulin resistance and low-grade inflammation before the onset of puberty. In prepubertal children born appropriate for gestational age (AGA) or small for gestational age (SGA), we assessed potential relationships between the aforementioned sequence and liver volume. SUBJECTS/METHODS: The study population consisted of 86 children (41 AGA and 45 SGA with catch-up growth; age (mean±s...

Purpose It has been demonstrated that circulating microRNA (miRNA) profiles are affected by physiological conditions. Several studies have demonstrated that miRNAs play important roles in the regulation of adiposity. However, few have investigated the relationship between circulating miRNAs and obesity, which has become a major public health problem worldwide. Current study investigated the association between circulating miRNAs and obesity in a Japanese population. Methods Obesity parameters, such as subcutaneous (SAT) and visceral fat (VAT) adipose tissue, body fat percentage, and body mass index (BMI) were assessed in a cross-sectional sample of 526 participants who attended health examinations in Yakumo, Japan...

OBJECTIVE: Obesity is associated with an increased risk of type 2 diabetes and cardiovascular complications. The risk depends significantly on adipose tissue distribution. Liraglutide, a glucagon-like peptide 1 analog, is associated with weight loss, improved glycemic control, and reduced cardiovascular risk. We determined whether an equal degree of weight loss by liraglutide or lifestyle changes has a different impact on subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) in obese subjects with prediabetes or early type 2 diabetes...

Obesity is associated with a loss of insulin-sensitivity and systemic dysglycemia, resulting in Type 2 diabetes, however the molecular mechanisms underlying this association are unclear. Through adipocyte patch-clamp studies, we recently showed that SWELL1 is required for the Volume-Regulated Anion Current (VRAC) in adipocytes and that SWELL1-mediated VRAC is activated by both mechanical and pathophysiological adipocyte expansion. We also demonstrated that adipocyte SWELL1 is required for maintaining insulin signaling and glucose homeostasis, particularly in the setting of obesity...

BACKGROUND: Visceral fat accumulation and muscle depletion have been identified as poor prognostic factors for various cancers. However, the significance of visceral adiposity and sarcopenic visceral obesity on outcomes after resection of pancreatic cancer remains unclear. METHODS: A retrospective analysis of 301 patients who underwent resection for localized pancreatic cancer between 2004 and 2015 was performed. The extent of visceral adiposity [visceral to subcutaneous adipose tissue area ratio (VSR)] and visceral obesity [visceral fat area (VFA)] were measured on preoperative computed tomography images, together with skeletal muscle index (SMI) and muscle attenuation (MA)...

OBJECTIVE: To investigate key enzymes of heme biosynthesis in human adipocytes and adipose tissue (AT). METHODS: Heme biosynthesis-related gene expression (ALAS1, ALAD, HMBS) was investigated in whole AT from humans (n = 178 and n = 75) and rats according to obesity status and during adipogenesis of human preadipocytes. The effects of aminotriazole (an ALAD inhibitor) and of ALAD knockdown were also studied. RESULTS: Consistent heme biosynthesis-related gene expression was detected in both subcutaneous AT (SAT) and visceral AT (VAT) and was significantly increased in SAT...

BACKGROUND/OBJECTIVES: Mutations in the Tubby gene (TUB) cause late-onset obesity and insulin resistance in mice and syndromic obesity in humans. Although TUB gene function has not yet been fully elucidated, studies in rodents indicate that TUB is involved in the hypothalamic pathways regulating food intake and adiposity. Aside from the function in central nervous system, TUB has also been implicated in energy metabolism in adipose tissue in rodents. We aimed to determine the expression and distribution patterns of TUB in man as well as its potential association with obesity...

BACKGROUND: Adipose tissue is now appreciated as the pivotal regulator of metabolic and endocrine functions. Subcutaneous (SC) fat, in contrast to visceral fat, may protect against metabolic syndrome and systemic inflammation. We demonstrated that chronic as well as acute UV exposure to the skin induces loss of underlying SC fat. UV-irradiated SC fat may produce chemokines or cytokines which modulate lipid homeostasis and secretion of adipokines. OBJECTIVES: We aim to elucidate UV-induced specific adipochemokines implicated in UV-induced modulation of SC fat...
