Mesenteric adipose tissue (MAT) inflammation is associated with non-alcoholic fatty liver disease (NAFLD), and immune cells play pivotal roles in the inflammation of adipose tissue. Here, we investigated the roles of MAT B lymphocytes in NAFLD. Mice fed with high-fat diet (HFD) and normal diet (ND) were killed in time gradients (4, 8 and 12 weeks). Compared with ND-fed mice, intra-hepatic CD45+ CD19+ B lymphocytes increased after 4 weeks (P < 0.01) of HFD feeding, and lasted until the 12th week, infiltrated earlier than CD45+ CD3+ T lymphocytes and CD45+ F4/80+ macrophages...

OBJECTIVE: Administration of glucagon (GCG) or GCG-containing co-agonists reduces body weight and increases energy expenditure. These actions appear to be transduced by multiple direct and indirect GCG receptor (GCGR)-dependent mechanisms. Although the canonical GCGR is expressed in brown adipose tissue (BAT) the importance of BAT GCGR activity for the physiological control of body weight, or the response to GCG agonism, has not been defined. METHODS: We studied the mechanisms linking GCG action to acute increases in oxygen consumption using wildtype (WT), Ucp1-/- and Fgf21-/- mice...

Provision of nutrients in appropriate amounts to meet nutrient requirements for growth, production, and reproduction is the basis for modern animal nutrition. Ration formulation systems predict nutrient requirements based on numerous inputs and then predict nutrient supply based on predicted intake and nutrient content of feeds. Energy systems are used to predict energy supply based on gross caloric content of feeds followed by adjustments for digestion and metabolism of ingested energy. Many models of energy supply use static coefficients of digestibility based on nutrient composition of feed...

GPR120 and GPR40 were recently reported as omega-3 (ω3) receptors with anti-inflammatory properties. Physical exercise could increase the expression of these receptors in the liver, improving hepatic metabolism in obesity and type 2 diabetes. Our aim was to investigate GPR120/40 in the liver of lean and obese mice after acute or chronic physical exercise, with or without the supplementation of ω3 rich flaxseed oil (FS), as well as assess the impact of exercise and FS on insulin signaling and inflammation...

Lipid metabolism disorders lead to vascular endothelial injury. Matrine is an alkaloid that has been used to improve obesity and diabetes and for the treatment of hepatitis B. However, its effect on lipid metabolism disorders and vascular injury is unclear. Here, we investigated the effect of matrine on high-fat diet fed mice and oxidized low-density lipoprotein (ox-LDL)-induced human umbilical vein endothelial cells (HUVECs). Computational virtual docking analyses, phosphoinositide 3-kinase (PI3K) and protein kinase C-α (PKCα) inhibitors were used to localize matrine in vascular injuries...

Our aim was to investigate the effects of 12-weeks of CT (i.e., high-intensity interval and resistance training) in Mapuche adults from Chile and in their peers of European descent. In total, 96 hyperglycemic adult women (mean age 46 years [95% confidence interval; 38, 53]) were divided in four groups: Mapuche CT (Map-CT, n=14) or control group (Map-CG, n=44), and European CT (Eur-CT, n=14) or control group (Eur-CG, n=23). The following endpoints were analyzed at baseline and after 12 weeks: anthropometric (body mass, body mass index, waist circumference), body composition (fat mass, muscle mass, lean mass), cardiovascular (systolic [SBP]/diastolic [DBP] blood pressure), metabolic (blood fasting glucose and total cholesterol), and muscle strength (handgrip of dominant/non-dominant arm)...

β2 Adrenergic receptors (β2 ARs) are G protein-coupled receptors (GPCRs) that are expressed in major insulin target tissues. β2 ARs play an important role in the regulation of lipid metabolism during aging; however, little is known about the significance of β2 ARs in the pathogenesis of hepatic fat accumulation in high-fat diet (HFD) mice. This study aims to examine the role of β2 AR in the development of nonalcoholic fatty liver disease (NAFLD) induced by HFD and the underlying mechanisms. Surprisingly, we found that genetic deletion of β2 AR significantly increased the liver weight of mice fed a HFD for 20 weeks compared to that of wild-type (WT) mice...

Non-alcoholic fatty liver disease (NAFLD) is characterized by altered intestinal microbiota and intestinal immune disorder. Here we investigated the role of mesenteric lymph node (MLN) CD4+ T lymphocytes in NAFLD. In high fat diet (HFD)-fed mice, the percentage ratios of Th1 to Th2 cells and Th17 to Treg cells were imbalanced in MLNs. Co-culture assays showed MLN CD4+ T lymphocytes from HFD-fed mice tended to migrate to the liver and promoted hepatic inflammation. Adoptive transfer of MLN CD4+ T lymphocytes from NAFLD mice to HFD-fed mice resulted in higher transaminase, worse hepatic inflammation and lipid accumulation...

Both high-fat diet and chronic circadian disruption have been associated with increased incidence of obesity and type 2 diabetes in humans. Chronically elevated glucocorticoids, which have considerable impacts on physiological processes such as intermediary metabolism, inflammation, and fat metabolism, have also been implicated in insulin resistance associated with obesity and diabetes. In this study, the effects of high-fat diet (HFD) or chronic circadian challenge in C57BL/6J mice on basal and stress-induced corticosterone (CORT) and blood glucose levels were assessed...

BACKGROUND: Proprotein convertase subtilisin / kexin type 9 (PCSK9) plays a critical role in the cholesterol metabolism by negatively regulating the low-density lipoprotein receptor (LDLR). Lipid metabolic and ovarian disorders are the common clinical manifestation of polycystic ovary syndrome (PCOS). Here, we intended to elucidate the role of PCSK9 in the pathogenesis of PCOS conducted on a human population in case-control design and animal part in an interventional study. METHODS: We firstly investigated the serum levels of PCSK9 in 46 PCOS patients compared with 49 healthy women as controls, and then developed a PCOS mouse model induced by dehydroepiandrosterone (DHEA) and a high-fat diet (HFD) to determine the role of PCSK9 in abnormal lipid metabolism and ovarian dysfunction of PCOS in four groups (n = 40 per group): control, PCOS mice, PCOS plus alirocumab group, and PCOS plus vehicle group...
