Obesity and an increased free fatty acid (FFA) level are tightly linked, leading to aberrant oxidative stress, inflammation, apoptosis, and progression to cardiovascular disorders. A20 is a ubiquitin-modifying enzyme that plays a significant role in the negative regulation of inflammatory response. Here, we study the role of A20 in obesity-induced heart injury and explore the underlying mechanisms. A20 expression was first increased in mouse hearts after 4 weeks of a high-fat diet (HFD) and then was gradually decreased in the following 20 weeks...

Reactive dicarbonyls stimulate production of advanced glycation endproducts, increase oxidative stress and inflammation and contribute to the development of vascular complications. We measured concentrations of dicarbonyls - methylglyoxal (MG), glyoxal (GL) and 3-deoxyglucosone (3-DG) - in the heart and kidney of a model of metabolic syndrome - hereditary hypertriglyceridemic rats (HHTg) and explored its modulation by metformin. Adult HHTg rats were fed a standard diet with or without metformin (300 mg/kg b...

Loquat (Eriobotrya japonica) leaf has displayed beneficial effect on metabolic syndrome. In our previously study, total sesquiterpene glycosides (TSG) isolated from Loquat leaf exhibited therapeutic effect on Non-alcoholic fatty liver disease (NAFLD) in vivo, but the accurate active compound remains unknown. Sesquiterpene glycoside 1 (SG1) is a novel compound, which is exclusively isolated from Loquat leaf, but its biological activity has been rarely reported. The present study was designed to evaluate the pharmacological effect of SG1, the main component of TSG, in oleic acid (OA)-induced HepG2 cell model of NAFLD with its related mechanisms of action...

Adipokines and other biomarkers were previously identified with roles in energy expenditure, appetite, satiety, and adiposity. Therefore, we investigated whether dietary weight loss-induced changes in adipokines and other biomarkers known to play a role in weight regulation or energy expenditure could predict weight regain in people with overweight and obesity. In this randomized controlled trial 26 males and 30 females (BMI: 28-35 kg/m(2)) followed either a low-calorie diet (LCD; 1250 kcal/day) for 12 weeks or a very-low-calorie diet (VLCD; 500 kcal/day) for 5 weeks followed by a weight stable period of 4 weeks (dietary intervention (DI) period) and a 9-month follow-up period...

Free fatty acids (FFAs) participate in a variety of physiological functions. FFAs are associated with the development of type 2 diabetes mellitus (T2DM). Uyghurs and Kazaks have a different prevalence of T2DM, which cannot be explained by traditional risk factors. This study aimed to examine FFAs as potential biomarkers to distinguish between healthy and T2DM Uyghurs and Kazaks. This was a prospective study conducted at the Xianjiang Medical University from 01/2007 to 06/2010 in Uyghurs and Kazaks. The subjects were grouped as T2DM patients (Uyghurs: n=39; Kazaks, n=21) and controls (Uyghurs: n=35; Kazaks, n=40)...

EDITORIAL

Whether non-alcoholic fatty liver disease (NAFLD) precedes insulin resistance (IR) or IR preludes/causes NAFLD has been long debated. Recent studies have shown that there are two phenotypes of NAFLD, 'genetic' vs 'metabolic' NAFLD. The former patients are more at risk of hepatocellular carcinoma and chronic liver disease the latter are more IR and at increased risk of type 2 diabetes (T2D). Even if they are not yet diabetics, from a metabolic point of view having NAFLD is equivalent to T2D with reduced peripheral glucose disposal and impaired suppression of hepatic glucose production, but without fasting hyperglycaemia...

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is a common result of obesity and metabolic syndrome. Hepatocyte injury and metabolic disorders are hallmarks of NAFLD. Stimulator of interferon genes (STING) and its downstream factor interferon regulatory factor 3 (IRF3) trigger inflammatory reaction in response to the presence of cytosolic DNA. STING has recently been shown to play an important role in early alcoholic liver disease. However, little is known about the role of STING-IRF3 pathway in hepatocyte injury...

Despite major advances in our understanding of transition and early lactation cow physiology and the use of advanced dietary, medical, and management tools, at least half of early lactation cows are reported to develop disease and over half of cow deaths occur during the first week of lactation. Excessive lipolysis, usually measured as plasma concentrations of free fatty acids (FFA), is a major risk factor for the development of displaced abomasum, ketosis, fatty liver, and metritis, and may also lead to poor lactation performance...

Ceramide is a key compound in sphingolipid metabolism. Dynamics of ceramide synthesis is important in the several biological processes, such as induction of apoptosis or insulin resistance. So far, its de novo synthesis rate was evaluated indirectly, based on the content of the compound, its intermediates and the activity of respective enzymes. The aim of the present study was to directly measure ceramide synthesis rate (FSR) in different muscle types under varied plasma FFA supply in rat with the use of [U-13C] palmitate tracer and LC/MS/MS...

In obese and diabetic patients, plasma free fatty acid (FFA) levels are often elevated and may play a causal role in insulin resistance and reactive oxygen species (ROS) production. We have previously shown that ursodeoxycholic acid (UDCA) has antioxidative activity through the phosphatidylinositol 3-kinase (PI3K)/Akt signaling-mediated glutathione production. In this study, we investigated the effects of UDCA on insulin response by analyzing intracellular ROS and the activation of the PI3K/Akt signaling pathway in HepG2 cells treated with palmitate...
