Increased liver fat may be caused by insulin resistance and adipose tissue inflammation or by the common I148M variant in PNPLA3 at rs738409, which lacks both of these features. We hypothesised that obesity/insulin resistance rather than liver fat increases circulating coagulation factor activities. We measured plasma prothrombin time (PT, Owren method), activated partial thromboplastin time (APTT), activities of several coagulation factors, VWF:RCo and fibrinogen, and D-dimer concentration in 92 subjects divided into groups based on insulin sensitivity [insulin-resistant ('IR') versus insulin-sensitive ('IS')] and PNPLA3 genotype (PNPLA3(148MM/MI) vs PNPLA3(148II))...

BACKGROUND AND OBJECTIVE: CD36 is implicated in fatty acid uptake in multiple tissues, including hepatocytes and adipocytes. Circulating CD36 (sCD36) is increased in non-alcoholic fatty liver disease (NAFLD).We explored this association further by investigating correlations between sCD36 levels, intrahepatic lipid content and markers of obesity in NAFLD patients and controls. METHODS: 111 NAFLD patients and 33 normal/overweight controls were included. Intrahepatic lipid content was measured by MR spectroscopy; and subgroups of participants had a dual-energy X-ray absorptiometry (n=99), magnetic resonance imaging (n=94, subcutaneous and visceral adipose tissue) and liver biopsy (n=28 NAFLD patients) performed...

BACKGROUND: The mammalian target of rapamycin complex 1 (mTORC1) is a central node in a network of signaling pathways controlling cell growth and survival. This multiprotein complex integrates external signals and affects different nutrient pathways in various organs. However, it is not clear how alterations of mTORC1 signaling in skeletal muscle affect whole-body metabolism. RESULTS: We characterized the metabolic phenotype of young and old raptor muscle knock-out (RAmKO) and TSC1 muscle knock-out (TSCmKO) mice, where mTORC1 activity in skeletal muscle is inhibited or constitutively activated, respectively...

Polycystic ovary syndrome (PCOS) is a common reproductive disorder that has many characteristic features including hyperandrogenemia, insulin resistance and obesity, which may have significant implications for pregnancy outcomes and long-term health of women. Daughters born to PCOS mothers constitute a high-risk group for metabolic and reproductive derangements, but no report has described potential growth and metabolic risk factors for such female offspring. Hence, we used a mouse model of dehydroepiandrosterone (DHEA)-induced PCOS to study the mechanisms underlying the pathology of PCOS by investigating the growth, developmental characteristics, metabolic indexes and expression profiles of key genes of offspring born to the models...

SCOPE: Virgin olive oil is an essential component of the Mediterranean diet. Its anti-oxidant and anti-inflammatory properties are mainly linked to phenolic contents. This study aims to evaluate the beneficial effects of a polyphenol-rich virgin olive oil (HPCOO) or olive oil without polyphenols (WPOO) in rats fed high-fat diet (HFD). METHODS AND RESULTS: Male Sprague-Dawley rats were divided into 4 groups based on the different types of diet: 1) Standard diet (STD); 2) HFD; 3) HFD containing WPOO and 4) HFD containing HPCOO...

We set out to explore the hypothesis that glycine attenuates non-alcoholic steatohepatitis (NASH) in rats and the possible mechanism by which is it does. Male Sprague-Dawley (SD) rats were fed a diet containing high fat and high sucrose (HSHF) for 24 weeks to induce NASH. Blood and liver tissues were sampled at selected time points throughout the study. Compared with control animals, the content of alanine transaminase (ALT), triglycerides (TGs), and free fatty acids (FFAs) in plasma and the TG and FFA content in the liver was increased from week 4 to 24...

Exogenous glucocorticoid administration results in hyperglycemia, insulin resistance, hepatic dyslipidemia, and hypertension, a constellation of findings known as Cushing's syndrome. These effects are mediated by the glucocorticoid receptor (GR). Because GR activation in liver and adipose has been implicated in metabolic syndrome (MS), we wanted to determine the role of GR in these tissues in the development of MS. Because GR knockout (KO) mice (whole-body KO) exhibit perinatal lethality due to respiratory failure, we generated tissue-specific (liver or adipose) GRKO mice using cre-lox technology...

Low-grade systemic inflammation in adipose tissues or liver, is an important etiologic factor in insulin resistance. LPS is an important element causing such metabolic inflammation, and intestinal flora is considered a major source of systemic LPS. We studied changes of intestinal microbiota associated with high-fat diet (HFD) that causes insulin resistance and metabolic stress. 16S rRNA gene sequencing showed that HFD significantly decreased the abundance of a mucin-degrading bacterium Akkermansia muciniphila compared to control diet...

AIMS/HYPOTHESIS: Low mitochondrial activity in adipose tissue is suggested to be an underlying factor in obesity and its metabolic complications. We aimed to find out whether mitochondrial measures are downregulated in obesity also in isolated adipocytes. METHODS: We studied young adult monozygotic (MZ) twin pairs discordant (n = 14, intrapair difference ΔBMI ≥ 3 kg/m(2)) and concordant (n = 5, ΔBMI < 3 kg/m(2)) for BMI, identified from ten birth cohorts of 22- to 36-year-old Finnish twins...

Fatty liver, or hepatic steatosis, is an alarmingly common pathology in western societies, in large part because if left unheeded, it can lead to life-threatening forms of nonalcoholic fatty liver disease, including nonalcoholic steatohepatitis, fibrosis, cirrhosis, and hepatocellular carcinoma. As such, it is essential that we attain a greater understanding of the pathways that control energy partitioning in the liver and ultimately how they are impacted by environmental factors. Here, we define the essential requirement for a member of the Ras-related protein in the brain (RAB)-like (RABL) clade of small GTPases, RABL2, in fatty acid metabolism including in microtubule-associated mitochondrial movement within the liver...

AIM: Non-alcoholic steatohepatitis (NASH) is a globally recognized liver disease. A methionine- and choline-deficient diet is used to induce NASH in mice; however, this diet also causes severe body weight loss. To resolve this issue, we examined the effects of methionine content in a high-fat and choline-deficient (HFCD) diet on body weight and the development of NASH in mice. METHODS: C57BL/6J mice (male, 10 weeks of age) were fed an L-amino acid rodent (control) diet, high-fat (HF) diet, or HFCD diet containing various amounts of methionine (0...

A high intake of fat and sucrose can dramatically increase bioactive lipids such as ceramides in tissues. Ceramides regulate several steps in the insulin signal pathway. The effects of n-3 PUFA on insulin resistance are inconsistent, especially in liver. We investigated the effect of n-3 PUFA (EPA/DHA 1 : 1) from fish oil on hepatic ceramides in a pre-diabetic animal model. Three groups of rats were fed standard feed, high fat high sucrose feed (HFHS) or HFHS enriched with n-3 PUFA. We investigated by lipidomic analysis how supplementation of a HFHS diet with n-3 PUFA modifies the hepatic ceramide profile triggered by a HFHS diet...

In veal calves, the major portion of digestible energy intake originates from milk replacer (MR), with lactose and fat contributing approximately 45 and 35%, respectively. In veal calves older than 4 mo, prolonged high intakes of MR may lead to problems with glucose homeostasis and insulin sensitivity, ultimately resulting in sustained insulin resistance, hepatic steatosis, and impaired animal performance. The contribution of each of the dietary energy sources (lactose and fat) to deteriorated glucose homeostasis and insulin resistance is currently unknown...

CONTEXT/OBJECTIVE: Acute pharmacological inhibition of 11β-hydroxysteroid-dehydrogenase 1 (11β-HSD1), which converts cortisone into the much more potent cortisol in peripheral tissues, results in reduction of total-, visceral- and liver fat, but not of insulin resistance. We now investigated whether lifelong alterations of 11β-HSD1 activity similarly affect these cardiometabolic risk parameters, by studying single nucleotide polymorphisms (SNPs) in the 11β-HSD1-coding gene (HSD11B1)...

Obesity, the major cause of the current global epidemic of type 2 diabetes (T2D), induces insulin resistance in peripheral insulin target tissues. Several mechanisms have been identified related to cross-talk between adipose tissue, skeletal muscle and liver. These mechanisms involve both increased free fatty acid release and altered secretion of adipokines from adipose tissue. A major determinant of metabolic health is the ability of subcutaneous adipose tissue (SAT) to store excess fat rather than allowing it to accumulate in ectopic depots including liver (i...

CONTEXT: Inflammation contributes to the development of metabolic and cardiovascular disease. Cushing's disease (CD), a state of chronic glucocorticoid (GC) excess characterized by visceral obesity and insulin resistance, may be associated with increased systemic inflammation. Cardiovascular mortality in CD remains elevated even after successful remission. It is unclear whether a chronic low-grade inflammatory state persists even after remission of CD, which may account for the increased CVD mortality...

BACKGROUND: Hepatic steatosis is strongly associated with insulin resistance. It has been reported that G0 /G1 switch gene 2 (G0s2) inhibits the lipolytic activity of adipose triglyceride lipase, which is a major lipase in the liver as well as in adipocytes. Moreover, G0s2 protein content is increased in the livers of high-fat diet (HFD)-fed rats. In the present study, we investigated the effect of hepatic G0s2 on insulin sensitivity in male Wistar rats. METHODS: Male Wistar rats were fed a 60% HFD for 4 weeks...

Methylsulfonylmethane (MSM), an organosulfur compound, has been used as a dietary supplement that can improve various metabolic diseases. However, the effect of MSM on obesity-linked metabolic disorders remains unclear. The goal of the current study is to determine whether MSM has beneficial effects on glucose and lipid homeostasis in obesity-associated pathophysiologic states. High-fat diet-induced obese (DIO) and genetically obese diabetic db/db mice treated with MSM (1%-5% v/v, by drinking water) were studied...
