BACKGROUND: Men and women react differently to some disease states, and women are reported to be more sensitive than men to the toxic effects of smoking. We examined the serum concentration of Klotho-related molecules, α-Klotho (αKl) and fibroblast growth factor (FGF)-21, and the influence of smoking on these molecules in both sexes. METHODS: Subjects included 90 men and 140 women in good health who underwent a health examination. RESULTS: Among male subjects, serum concentrations of FGF-21, soluble sαKl, and inflammation-related cytokine interleukin (IL)-6 were significantly higher in smokers than in never-smokers...

Aims: Brown adipose tissue (BAT) has been identified as an endocrine organ that maintains metabolic homeostasis; however, the effects on atherosclerosis remain undefined. Here, we investigated the effect of experimental BAT transplantation on atherosclerosis. Methods and Results: Interscapular BAT was dissected from 12-week-old wild-type mice and transplanted into the visceral cavity of 12-week-old apoE-/- mice. Oil-red O staining of whole aortas after 3 months of a high-cholesterol diet showed a significant decrease in atherosclerotic lesion area in BAT-transplanted mice by 20% compared with the sham control mice...

Renal epithelial cells are exposed to mechanical forces due to flow-induced shear stress within the nephrons. Shear stress is altered in renal diseases caused by tubular dilation, obstruction and hyperfiltration, which occur to compensate for lost nephrons. Fundamental in regulation of shear stress are primary cilia and other mechano-sensors, and defects in cilia formation and function have profound effects on development and physiology of kidneys and other organs. We applied RNA sequencing to get a comprehensive overview of fluid-shear regulated genes and pathways in renal epithelial cells...

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...

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...
