Obesity has become a significant global health problem, and is a high risk factor for a variety of metabolic diseases. Fibroblast growth factor (FGF) 15 plays an important role in the regulation of metabolism. Xenobiotic-sensing nuclear receptors pregnane X receptor (PXR/NR1I2) and constitutive androstane receptor (CAR/NR1I3) play important roles in xenobiotic detoxification and metabolism, and also are involved in the regulation of energy metabolism. However, the effects that PXR and CAR have on the regulation of FGF15 are unknown...

Bile acid (BA) production in mice is regulated by hepatic farnesoid X receptors and by intestinal fibroblast growth factor (FGF)-15 (in humans, FGF-19), a suppressor of BA synthesis that also reduces serum triglycerides and glucose. Cholestyramine treatment reduces FGF-19 and induces BA synthesis, whereas plasma triglycerides may increase from unclear reasons. We explored whether FGF-19 may suppress BA synthesis and plasma triglycerides in humans by modulation of FGF-19 levels through long-term cholestyramine treatment at increasing doses...

Fibroblast growth factor (FGF) 21 belongs to the FGF superfamily that is involved in cell proliferation and differentiation, neural development, angiogenesis, and metabolism. FGF21 requires β-Klotho as a co-receptor. Tissues involved in metabolism such as the liver, adipose tissues, skeletal muscle, and pancreas express FGF21. Starvation increases hepatic expression of FGF21, which then acts centrally to increase hepatic gluconeogenesis. FGF21 also increases fatty acid oxidation. This may be relevant in cold exposure, when expression of FGF21 is induced...

INTRODUCTION: Patients with hypogonadism are at increased risk of cardiac and metabolic diseases and osteoporosis. Vitamin D and Fibroblast growth factor-23 (FGF-23) play role in the regulation of bone mineral metabolism and endothelial functions. Low vitamin D levels are reported in hypogonadism, while there is no data about the effect of testosterone replacement therapy (TRT). We investigated the effect of TRT on vitamin D and FGF-23 levels along with endothelial functions and insulin resistance in hypogonadal patients...

BACKGROUND: In early breast cancer patients, the effects of hormonal therapy (tamoxifen and aromatase inhibitors) on plasma fibroblast growth factor 21 (FGF-21), lipid levels and body composition have not yet been investigated. Therefore, we aimed to analyze the relationship between FGF-21 and body composition as well as the effects of tamoxifen and aromatase inhibitors on plasma lipid levels, FGF-21, and body composition. METHODS: A total of 72 patients were treated with either tamoxifen or aromatase inhibitors due to their menopausal status after adjuvant radiotherapy...

C1q/TNF-related protein 1 (CTRP1) is a conserved plasma protein of the C1q family with notable metabolic and cardiovascular functions. We have previously shown that CTRP1 infusion lowers blood glucose and that transgenic mice with elevated circulating CTRP1 are protected from diet-induced obesity and insulin resistance. Here, we used a genetic loss-of-function mouse model to address the requirement of CTRP1 for metabolic homeostasis. Despite similar body weight, food intake, and energy expenditure, Ctrp1 knockout (KO) mice fed a low-fat diet developed insulin resistance and hepatic steatosis...

AIM: Fibroblast growth factor 21 (FGF21) has been demonstrated to be a metabolic regulator with beneficial effects. Several studies have shown that type 2 diabetes mellitus (T2DM) patients have increased FGF21 levels and decreased expression of FGF receptors, suggesting a state of 'FGF21 resistance'. The aim of this study was to investigate the effects of the glucagon-like peptide (GLP)-1 receptor agonist exenatide on FGF21 levels and other metabolic parameters in patients with newly diagnosed T2DM...

BACKGROUND AND AIMS: The role of the different factors associated with fatty liver is still poorly defined. We evaluated the relationships between liver fat content (LF) and metabolic, inflammatory and nutritional factors in a homogeneous cohort of individuals at high cardio-metabolic risk. METHODS AND RESULTS: In 70 individuals with high waist circumference and at least one more criterion for metabolic syndrome enrolled in a nutritional intervention study, LF was evaluated at baseline by hepatic/renal echo intensity ratio (H/R), together with dietary habits (7-day dietary record), insulin sensitivity and β-cell function (fasting and OGTT-derived indices), fasting and postprandial plasma GLP-1 and lipoproteins, and plasma inflammatory markers...

During the periparturient phase, cows are typically in an inflammation-like condition, and it has been suggested that inflammation associated with the development of stress of the endoplasmic reticulum (ER) in the liver contributes to the development of fatty liver syndrome and ketosis. In the present study, we investigated the hypothesis that feeding grape seed and grape marc meal extract (GSGME) as a plant extract rich in flavonoids attenuates inflammation and ER stress in the liver of dairy cows. Two groups of cows received either a total mixed ration as a control diet or the same total mixed ration supplemented with 1% of GSGME over the period from wk 3 prepartum to wk 9 postpartum...

While aging is unavoidable, the aging mechanism is still unclear because of its complexity. Smoking causes premature death and is considered as an environmental aging accelerator. In the present study, we focused on the influence of smoking to the serum concentration of anti-aging protein α-klotho (αKl) and the β-klotho-associated protein fibroblast growth factor (FGF)-21 in men. Subjects consisted of apparently healthy men over 40 years of age who underwent health examination. Physical and biochemical parameters, including the levels of several cytokines and growth factors, were obtained from the subjects...

BACKGROUND: A fascinating aspect of bile acid homeostasis is the coordination between bile acid uptake in intestine and hepatic bile acid synthesis. In response to bile acid uptake in enterocytes, farnesoid X receptor is activated and induces transcription of fibroblast growth factor (FGF)15 in mice, or FGF19 in humans. FGF15/19 is secreted into the enterohepatic circulation, and through activation of hepatic receptors, leads to repression of Cyp7a1, a rate-limiting enzyme for bile acid synthesis...

The size and composition of the circulating bile acid (BA) pool are important factors in regulating the human gut microbiota. Disrupted regulation of BA metabolism is implicated in several chronic diseases. Bile salt hydrolase (BSH)-active Lactobacillus reuteri NCIMB 30242, previously shown to decrease LDL-cholesterol and increase circulating BA, was investigated for its dose response effect on BA profile in a pilot clinical study. Ten otherwise healthy hypercholesterolemic adults, recruited from a clinical trial site in London, ON, were randomized to consume delayed release or standard release capsules containing L...

INTRODUCTION: Fibroblast growth factors (FGFs) belong to the FGF superfamily with diverse biological functions, including proliferation, cellular differentiation, wound repair, angiogenesis and tumorigenesis. The ability to reduce liver fat content and concentrations of triglycerides, total cholesterol and plasma glucose, and to improve sensitivity and limit pro-lipogenic properties of insulin, makes FGF19 a promising therapeutic target for the treatment of metabolic syndrome. FGF19 regulates bile acid biosynthesis in the bile duct, glucose metabolism and vitamin D and phosphate homeostasis, raises the metabolic rate, reduces body weight, and ameliorates diabetes in mice...

The relationship between the intestinal microbiota and the hypocholesterolemic and antiobesity effects of whole grape seed flour from white and red winemaking was evaluated. Male Golden Syrian hamsters were fed a high-fat (HF) control diet or a HF diet supplemented with 10% partially defatted grape seed flours from either Chardonnay (ChrSd) or Cabernet Sauvignon (CabSd) grapes for 3 weeks. The numbers of total bacteria and relative abundances of Bifidobacterium spp., Lactobacillus spp., and Firmicutes in feces were significantly lower, while the relative abundance of Bacteroides fragilis was greater than the control from feeding the ChrSd diet...

BACKGROUND: Patients with coronary heart disease (CHD) without classical cardiovascular risk factors (CRFs) are uncommon, and their profile has not been thoroughly studied. In CHD patients, we have assessed the differences in several biomarkers between those with and without CRF. METHODS: We studied 704 patients with CHD, analyzing plasma levels of biomarkers related to inflammation, thrombosis, renal damage, and heart failure: high-sensitivity C-reactive protein (hs-CRP), monocyte chemoattractant protein-1 (MCP-1), galectin-3, N-terminal fragment of brain natriuretic peptide (NT-pro-BNP), calcidiol (vitamin D metabolite), fibroblast growth factor-23 (FGF-23), parathormone, and phosphate...

Thyroid hormone (TH) acts through specific receptors (TRs), which are conditional transcription factors, to induce fibroblast growth factor 21 (FGF21), a peptide hormone that is usually induced by fasting and that influences lipid and carbohydrate metabolism via local hepatic and systemic endocrine effects. While TH and FGF21 display overlapping actions when administered, including reductions in serum lipids, according to the current models these hormones act independently in vivo. In this study, we examined mechanisms of regulation of FGF21 expression by TH and tested the possibility that FGF21 is required for induction of hepatic TH-responsive genes...
