Metabolism of fructose in B-cells: A C NMR spectroscopy based stable isotope tracer study.

Earlier studies on glucose metabolism in B-cells suggested an active TCA cycle in both naïve B cells and differentiated IgA plasma cells. Glycolysis was shown to be more active in IgA plasma cells than naïve B-cells. There have been no reports on the metabolism of fructose in B-cells. Fructose is a major sugar present in the western diet. Thus, we have investigated the metabolism of fructose in B-cells including the effect of glucose on the metabolism of fructose. In this study, using C NMR spectroscopy a...


Ketohexokinase Knockout Mice, a Model for Essential Fructosuria, Exhibit Altered Fructose Metabolism and are Protected from Diet-induced Metabolic Defects.

Fructose consumption in humans and animals has been linked to enhanced de novo lipogenesis, dyslipidemia and insulin resistance. Hereditary deficiency of Ketohexokinase (KHK), the first enzymatic step in fructose metabolism, leads to essential fructosuria in humans, characterized by elevated levels of blood and urinary fructose following fructose ingestion, but is otherwise clinically benign. To address whether KHK deficiency is associated with altered glucose and lipid metabolism, a KHK knockout (KO) mouse...

Fibroblast growth factor 21 and fructose dynamics in humans.

Fructose consumption is a risk factor for metabolic disease. We recently demonstrated that fibroblast growth factor 21 (FGF21), a metabolic hormone involved in lipid and glucose metabolism, is acutely stimulated in humans by 75 g oral fructose, with peak levels occurring 2 h after consumption. This study reports on the dose dependency and reproducibility of the FGF21 response to fructose.


Biglycan gene connects metabolic dysfunction with brain disorder.

Dietary fructose is a major contributor to the epidemic of diabetes and obesity, and it is an excellent model to study metabolic syndrome. Based on previous studies that Bgn gene occupies a central position in a network of genes in the brain in response to fructose consumption, we assessed the capacity of Bgn to modulate the action of fructose on brain and body. We exposed male biglycan knockout mice (Bgn) to fructose for 7 weeks, and results showed that Bgn mice compensated for a decrement in learning an...

Short-term tamoxifen treatment has long-term effects on metabolism in high-fat diet-fed mice with involvement of Nmnat2 in POMC neurons.

Short-term tamoxifen treatment has effects on lipid and glucose metabolism in mice fed chow. However, its effects on metabolism in mice fed high-fat diet (HFD) and the underlying mechanisms are unclear. Here, we show that tamoxifen treatment for 5 days decreases fat mass for as long as 18 weeks in mice fed HFD. Tamoxifen alters mRNA levels of some genes involved in lipid metabolism in white adipose tissue and improves glucose and insulin tolerance as well as hepatic insulin signaling for 12 to 20 weeks. Pro...

Evolution, regulation, and function of porcine selenogenome.

Much less research on regulation and function of selenoproteins has been conducted in domestic pigs than in rodents or humans, although pigs are an excellent model of human nutrition and medicine and pork is a widely consumed meat in the world. Phylogenetically, the 25 identified porcine selenoproteins fell into two primitive groups, and might be further divided into three parallel branches. Despite a high similarity to that of humans and rodents, the porcine selenoproteome exhibited the closest evolutionar...

Utilization of lactic acid in human myotubes and interplay with glucose and fatty acid metabolism.

Once assumed only to be a waste product of anaerobe glycolytic activity, lactate is now recognized as an energy source in skeletal muscles. While lactate metabolism has been extensively studied in vivo, underlying cellular processes are poorly described. This study aimed to examine lactate metabolism in cultured human myotubes and to investigate effects of lactate exposure on metabolism of oleic acid and glucose. Lactic acid, fatty acid and glucose metabolism were studied in myotubes using [C(U)]lactic acid...

Role of Human Brown Fat in Obesity, Metabolism and Cardiovascular Disease: Strategies to Turn Up the Heat.

Human brown adipose tissue (BAT) was re-discovered in 2009 by several independent groups, who showed that it is present and active in adults, as judged from the profound uptake of the glucose analogue radiotracer F-fluorodeoxyglucose in positron-emission tomography and computed tomography scan analysis after cold exposure. A potential clinical implication of activating BAT relates to its high metabolic activity and its potential role in stimulating energy expenditure (i.e. resting energy expenditure, meal-i...

A mathematical analysis of adaptations to the metabolic fate of fructose in essential fructosuria subjects.

Fructose is a major component of Western diets and is implicated in the pathogenesis of obesity and type 2 diabetes. In response to an oral challenge, the majority of fructose is cleared during "first-pass" liver metabolism, primarily via phosphorylation by ketohexokinase (KHK). A rare benign genetic deficiency in KHK, called essential fructosuria (EF), leads to altered fructose metabolism. The only reported symptom of EF is the appearance of fructose in the urine following either oral or intravenous fructo...

Neonatal intake of oleanolic acid attenuates the subsequent development of high fructose diet-induced non-alcoholic fatty liver disease in rats.

Dietary manipulations during the early postnatal period are associated with the development of metabolic disorders including non-alcoholic fatty liver disease (NAFLD) or long-term protection against metabolic dysfunction. We investigated the potential hepatoprotective effects of neonatal administration of oleanolic acid (OA), a phytochemical, on the subsequent development in adulthood, of dietary fructose-induced NAFLD. Male and female suckling rats (n=112) were gavaged with; distilled water (DW), OA (60 mg...

Improved glucose metabolism by Eragrostis tef potentially through beige adipocyte formation and attenuating adipose tissue inflammation.

Teff is a staple food in Ethiopia that is rich in dietary fiber. Although gaining popularity in Western countries because it is gluten-free, the effects of teff on glucose metabolism remain unknown.

Influence of Probiotics Administration on Gut Microbiota Core: A Review on the Effects on Appetite Control, Glucose, and Lipid Metabolism.

An increasing number of studies has shown that dietary probiotics exert beneficial health effects in both humans and animals. It is well established that gut microbiota play a pivotal role in regulating host metabolism, and a growing number of studies has elucidated that probiotics positively interfere with gut microbiota. Accumulating evidence shows that probiotics, through their metabolic activity, produce metabolites that in turn contribute to positively affect host physiology. For these reasons, probiot...

Dose-dependent quantitative effects of acute fructose administration on hepatic de novo lipogenesis in healthy humans.

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-C]-acetate was infused to measure DNL in the fasting state and during...

Effects of dietary lipid sources on hepatic nutritive contents, fatty acid composition and proteome of Nile tilapia (Oreochromis niloticus).

Dietary oils of varying fatty acid composition have been used in tilapia feeds; nevertheless, investigation of their effects on metabolism and physiological processes has been limited. Therefore, in this study, using proteomic technology, the effects of different dietary lipids (DLs) on hepatic lipid metabolism and physiological processes were investigaed in Nile tilapia (Oreochromis niloticus). Fish were fed with different DL, which included palm oil (PO), linseed oil (LO) and soybean oil (SBO) for 90 da...

ChREBP deficiency leads to diarrhea-predominant irritable bowel syndrome.

Fructose malabsorption is a common digestive disorder in which absorption of fructose in the small intestine is impaired. An abnormality of the main intestinal fructose transporter proteins has been proposed as a cause for fructose malabsorption. However the underlying molecular mechanism for this remains unclear. In this study, we investigated whether carbohydrate response element-binding protein (ChREBP) plays a role in intestinal fructose absorption through the regulation of genes involved in fructose tr...

Erythroferrone is not required for the glucoregulatory and hematologic effects of chronic erythropoietin treatment in mice.

Erythropoietin (EPO) acts on erythroid progenitor cells to promote their survival and differentiation to mature erythrocytes. Along with this canonical role, EPO is also reported to modulate energy metabolism, resulting in improved glucose tolerance and insulin sensitivity. EPO also stimulates the production of the hormone erythroferrone (ERFE) which acts to suppress hepcidin production, thus increasing dietary iron absorption and mobilizing stored iron for use in erythropoiesis. ERFE (initially termed myon...

Protective Effects of Ellagitannin-Rich Strawberry Extracts on Biochemical and Metabolic Disturbances in Rats Fed a Diet High in Fructose.

The present study compares the effects of two dietary strawberry extracts rich in monomeric (ME) or dimeric (DE) ellagitannins (ETs) on gastrointestinal, blood and tissue biomarkers in Wistar rats fed high-fructose diets. Both strawberry extracts beneficially affect the antioxidant status and lipid profile of the liver and serum. The ME extract shows a greater ability to inhibit lipid peroxidation in kidneys, more effectively decreases serum and liver triglycerides, and exerts greater anti-inflammatory effe...

Role of rs670 variant of APOA1 gene on lipid profile, insulin resistance and adipokine levels in obese subjects after weight loss with a dietary intervention.

The aim of this study was to analyze the effects of rs670 APOA1 gene polymorphism on obesity parameters, lipid profile, glucose metabolism markers, blood pressure and adipokine levels after a hypocaloric diet with Mediterranean pattern.

Continuous Glucose Monitoring at High Altitude-Effects on Glucose Homeostasis.

Exposure to high altitude has been shown to enhance both glucose and lipid utilization depending on experimental protocol. In addition, high and low blood glucose levels have been reported at high altitude. We hypothesized that gradual ascent to high altitude results in changes in glucose levels in healthy young adults.

The acute effects of citrus flavanones on the metabolism of glycogen and monosaccharides in the isolated perfused rat liver.

Citrus flavanones are often linked to their antihyperglycemic properties. This effect may be in part due to the inhibition of hepatic gluconeogenesis through different mechanisms. One of the possible mechanisms appears to be impairment of oxidative phosphorylation, which may also interfere with glycogen metabolism. Based on these facts, the purpose of the present study was to investigate the effects of three citrus flavanones on glycogenolysis in the isolated perfused rat liver. Hesperidin, hesperetin, and ...

A systematic meta-analysis of oxygen-to-glucose and oxygen-to-carbohydrate ratios in the resting human brain.

Glucose is the predominant fuel supporting brain function. If the brain's entire glucose supply is consumed by oxidative phosphorylation, the molar ratio of oxygen to glucose consumption (OGI) is equal to 6. An OGI of less than 6 is evidence of non-oxidative glucose metabolism. Several studies have reported that the OGI in the resting human brain is less than 6.0, but the exact value remains uncertain. Additionally, it is not clear if lactate efflux accounts for the difference between OGI and its theoretica...

GLUT5 increases fructose utilization and promotes tumor progression in glioma.

Fructose is now such an important component of human diets, and several studies have found that some cancer cells could utilize fructose to overcome low glucose micro-environment, but the study on the role of fructose in glioma is rare. To explore the role of fructose in glioma, we detected the proliferation and colony formation ability of glioma cells in fructose medium, and found that the abilities of proliferation and colony formation of glioma cells in fructose medium were similar with abilities in gluc...

Metabotypes Related to Meat and Vegetable Intake Reflect Microbial, Lipid and Amino Acid Metabolism in Healthy People.

The objective of this study was to develop a new methodology to identify the relationship between dietary patterns and metabolites indicative of food intake and metabolism.

Effects of perinatal exposure to BPA and its alternatives (BPS, BPF and BPAF) on hepatic lipid and glucose homeostasis in female mice adolescent offspring.

The widespread application of bisphenols (BPs) makes them ubiquitous in the natural environment and poses many potential risks. In this study, we examined the effects of perinatal exposure to BPA and its 3 alternatives (BPS, BPF, and BPAF) on lipid and glucose homeostasis in female mice adolescent offspring. Specifically, BPA exposure promoted the expression of hepatic lipid synthesis and fatty acid accumulation genes, resulting in a significant increase in 2 free fatty acids contents. BPS exposure caused a...

Blocking of STAT-3/SREBP1-mediated glucose-lipid metabolism is involved in dietary phytoestrogen-inhibited ovariectomized-induced body weight gain in rats.

Postmenopausal women have a decline in circulating estrogen levels and are more prone to obesity and its related metabolic diseases than premenopausal women are. The absence of safe and effective conventional treatments for postmenopausal obesity has changed the focus to natural products as alternative remedies. Here, ovariectomized rats and LO2 cells were used to study the molecular basis of the effect of dietary phytoestrogens on body weight gain and hepatic steatosis. Dietary phytoestrogens can inhibit o...
