Research in recent years on peroxisome proliferator-activated receptor (PPAR)β/δ indicates that it plays a key role in the maintenance of energy homeostasis, both at the cellular level and within the organism as a whole. PPARβ/δ activation might help prevent the development of metabolic disorders, including obesity, dyslipidaemia, type 2 diabetes mellitus and non-alcoholic fatty liver disease. This review highlights research findings on the PPARβ/δ regulation of energy metabolism and the development of diseases related to altered cellular and body metabolism...

Fructose feeding increases hepatic de novo lipogenesis (DNL) and is associated with non-alcoholic fatty liver disease. Little is known, however, about individual variation in susceptibility to fructose stimulation of DNL. In this three-period, cross-over study, seventeen healthy male subjects were enrolled to evaluate the within and between subject variability of acute fructose feeding on hepatic fractional DNL. During each assessment, [1-13 C1 ]-acetate was infused to measure DNL in the fasting state and during fructose feeding...

Non-alcoholic fatty liver disease and steatohepatitis (NAFLD and NASH) account for the majority of liver disease in industrialized countries. However, the pathogenesis still unclear. Long non-coding RNAs (lncRNAs) has been reported to be involved in various pathophysiological processes. Here, we reported a novel role of lncARSR in hepatic lipogenesis in NAFLD. The expression of lncARSR was induced both in NAFLD patients and mouse model, as well as in hepatocytes treated with fatty acid. Moreover, overexpression of lncARSR enhanced while knockdown of lncARSR ameliorated hepatic lipid accumulation in vivo and in vitro...

Alcoholism is accompanied with a high incidence of cardiac morbidity and mortality due to the development of alcoholic cardiomyopathy, manifested as dilation of one or both ventricles, reduced ventricular wall thickness, myofibrillary disarray, interstitial fibrosis, hypertrophy and contractile dysfunction. Several theories have been postulated for the etiology of alcoholic cardiomyopathy including ethanol/acetaldehyde toxicity, mitochondrial production of reactive oxygen species, oxidative injury, apoptosis, impaired myofilament Ca2+ sensitivity and protein synthesis, altered fatty acid extraction and deposition, as well as accelerated protein catabolism...

Cell-to-cell communication is a fascinating process that is essential for maintaining tissue and whole-body homeostasis. Extracellular vesicles (EVs) are cell-derived membrane-bound nanoparticles that are a means of communication between cells. Accumulating evidence indicates that EVs can render either beneficial or harmful outcomes, depending on the specific cargos (e.g. proteins, lipids, RNAs) transferred between cells. EVs also have great value as diagnostic and prognostic markers of disease because they are present in a variety of biological fluids and carry bioactive molecules from their cells or tissues of origin...

Peroxisome proliferator-activated receptor gamma (PPARγ) participates in the process of insulin resistance (IR), a crucial pathophysiology in non-alcoholic fatty liver disease (NAFLD). Meanwhile, suppressor of cytokine signaling3 (SOCS3) also regulates IR in NAFLD. Both PPARγ and SOCS3 play a role in NAFLD through regulating IR, while it is unclear whether these two proteins interact to regulate hepatic steatosis. PPARγ, SOCS3 and its associated JAK2/STAT3 pathway were analyzed using Kuppfer cells (KCs) treatment with LPS and BRL-3A cells treatment with palmitic acid, KC-conditioned medium (KCCM), PPARγ agonist rosiglitazone (ROZ) or JAK2 inhibitor AG490 to demonstrate the role of PPARγ and SOCS3 in hepatocytes steatosis...

Objective: Thyroid hormones are ubiqiutiously involved in human metabolism. However, the precise molecular patterns associated with alterations in thyroid hormones levels remain to be explored in detail. A number of recent studies took great advantage of metabolomics profiling to outline metabolic actions of thyroid hormones in humans. Methods: Among 952 participants of the Study of Health in Pomerania data on serum free thyroxine (FT4) and thyrotropin (TSH) as well as comprehensive (non-)targeted metabolomics data of plasma and urine samples were available...

Background: The Norwegian food-based dietary guidelines (FBDG) aim at reducing the risk of developing chronic diseases and promote overall health. We studied the effect of the Norwegian FBDG in colorectal cancer (CRC) patients. There is a need for a time-efficient dietary assessment tool measuring adherence to these guidelines in patients treated for dietary dependent cancer, such as CRC patients. Objective: To evaluate a new short food frequency questionnaire (NORDIET-FFQ), developed to estimate adherence to the Norwegian FBDG among CRC patients...

For many years it has been known that high doses of long chain omega-3 fatty acids are beneficial in the treatment of hypertriglyceridaemia. Over the last three decades, there has also been a wealth of in vitro and in vivo data that has accumulated to suggest that long chain omega-3 fatty acid treatment might be beneficial to decrease liver triacylglycerol. Several biological mechanisms have been identified that support this hypothesis; notably, it has been shown that long chain omega-3 fatty acids have a beneficial effect: a) on bioactive metabolites involved in inflammatory pathways, and b) on alteration of nuclear transcription factor activities such as peroxisome proliferator-activated receptors (PPARs), sterol regulatory element-binding protein 1c (SREBP-1c) and carbohydrate-responsive element-binding protein (ChREBP), involved in inflammatory pathways and liver lipid metabolism...

BACKGROUND: There is growing interest in the beneficial health effects of certain fruits, such as pomegranate, and their by-products, like vinegar. Vinegars contain antioxidant compounds such as polyphenols, which can scavenge free radicals in the body. In this study, the antioxidant properties (ABTS and DPPH scavenging capacities) and global polyphenolic composition of a new functional product, namely a pomegranate vinegar produced in the laboratory from the Gabsi variety, were evaluated and compared with those of commercial wine vinegars (Sherry and Rioja red wine Spanish vinegars)...

Background & aims : Non-alcoholic fatty liver disease (NAFLD) associates with low levels of serum plant sterols in cross-sectional studies. However, parenterally given plant sterols may lead to liver injury. In addition, it has been suggested that the hepatic sterol transport mechanisms are altered in NAFLD. Therefore, we investigated the association between serum, liver and bile plant sterols and sitostanol with NAFLD. Methods : Out of the 138 individuals (age: 46.3±8.9, BMI: 43.3±6.9 kg/m², 28% men and 72% women), 44 could be histologically categorized to have normal liver, and 94 to have NAFLD...

BACKGROUND: Recent evidence supports that the gut microbiota may be involved in the pathophysiology of non-alcoholic fatty liver disease (NAFLD), and may also offer avenues for treatment or prevention. METHODS: We investigated the associations among gut microbiota, diet and hepatic fat fraction (HFF) in 107 adolescents. Magnetic Resonance Imaging (MRI) was used to assess HFF, and 16S rRNA gene sequencing was performed on collected fecal samples. Dietary intake was assessed using Food Frequency Questionnaires...

Obesity is the pandemic of the 21st century. Obesity comorbidities, including hypertension, dyslipidaemia and glucose intolerance define metabolic syndrome, which increases mortality risk and decreases the quality of life. Compared with lifestyles (diet and physical activity) and pharmacological interventions, bariatric surgery is by far the most effective treatment for obesity and its comorbidities. This minimally invasive surgical treatment is based on an increase of satiety (by hormonal regulation and decreasing stomach volume) or a decrease in nutrient retention (gastric and/or intestinal resection)...

Alcohol liver disease (ALD) is one of the major chronic liver diseases worldwide, ranging from fatty liver, alcoholic hepatitis, cirrhosis, and potentially hepatocellular carcinoma. Epidemiological studies suggest a potential link between ALD and impaired circadian rhythms, but the role of hepatic circadian proteins in the pathogenesis of ALD remains unknown. Here we show that the circadian clock protein BMAL1 in hepatocytes is both necessary and sufficient to protect mice from alcohol liver disease. Ethanol diet-fed mice with liver-specific knockout (Bmal1-LKO) or depletion of Bmal1 develop more severe liver steatosis and injury as well as a simultaneous suppression of both de novo lipogenesis and fatty acid oxidation, which can be rescued by the supplementation of synthetic PPARα ligands...
