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...


The Small Intestine Converts Dietary Fructose into Glucose and Organic Acids.

Excessive consumption of sweets is a risk factor for metabolic syndrome. A major chemical feature of sweets is fructose. Despite strong ties between fructose and disease, the metabolic fate of fructose in mammals remains incompletely understood. Here we use isotope tracing and mass spectrometry to track the fate of glucose and fructose carbons in vivo, finding that dietary fructose is cleared by the small intestine. Clearance requires the fructose-phosphorylating enzyme ketohexokinase. Low doses of fructos...

Mechanistically different effects of fat and sugar on insulin resistance, hypertension and gut microbiota in rats.

Insulin resistance (IR) and impaired glucose tolerance (IGT) are the first manifestations of diet-induced metabolic alterations leading to type-2 diabetes, while hypertension is the deadliest risk factor of cardiovascular disease. The roles of dietary fat and fructose in the development of IR, IGT and hypertension are controversial. We tested the long-term effects of an excess of fat or sucrose (fructose/glucose) on healthy male Wistar Kyoto (WKY) rats. Fat affects IR and IGT earlier than fructose through l...


Dietary Fructose Metabolism By Splanchnic Organs: Size Matters.

The initial metabolism of fructose is thought to primarily take place in the liver. Using stable isotope labeling combined with tissue and arterio-venous sampling, Jang et al. (2018) demonstrate that in mice, the small intestine is the primary site of fructose metabolism. This raises important questions about fructose handling in humans.

The FGF21 response to fructose predicts metabolic health and persists after bariatric surgery in obese humans.

Fructose consumption has been implicated in the development of obesity and insulin resistance. Emerging evidence shows that fibroblast growth factor 21 (FGF21) has beneficial effects on glucose, lipid, and energy metabolism and may also mediate an adaptive response to fructose ingestion. Fructose acutely stimulates circulating FGF21 consistent with a hormonal response. We aimed to evaluate whether fructose-induced FGF21 secretion is linked to metabolic outcomes in obese humans before and after bariatric sur...

Effects of evolving lipid-lowering drugs on carbohydrate metabolism.

The understanding that statins reduce but not eliminate the cardiovascular risk associated with disturbed lipid metabolism and the existence of forms of dyslipidemia that are unresponsive or only partially responsive to statins have led to the development of many novel lipid-lowering drugs. Accumulating evidence suggests that the interplay between carbohydrate and lipid metabolism is bidirectional. Thus, any intervention that affects lipid metabolism has the potential to influence the homeostasis of glucose...

The acute effects on duodenal gene expression in healthy men following consumption of a low-fat meal enriched with theobromine or fat.

Increasing apoA-I synthesis may improve HDL functionality and lower CVD risk. As theobromine and fat increase fasting apoA-I concentrations, and the intestine is involved in apoA-I production, the acute effects of both were studied on duodenal gene transcription to better understand underlying mechanisms. In this crossover study, 8 healthy men received once a low fat (LF) meal, a LF meal plus theobromine (850 mg), or a high fat (HF) meal. Five hours after meal intake duodenal biopsies were taken for micro...

Effects of short-term sex steroid suppression on dietary fat storage patterns in healthy males.

Hypogonadism in males is associated with increased body fat and altered postprandial metabolism, but mechanisms remain poorly understood. Using a cross-over study design, we investigated the effects of short-term sex hormone suppression with or without testosterone add-back on postprandial metabolism and the fate of dietary fat. Eleven healthy males (age: 29 ± 4.5 year; BMI: 26.3 ± 2.1 kg/m2 ) completed two 7-day study phases during which hormone levels were altered pharmacologically to produce a lo...

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...

Fructose and glucose regulate mammalian target of rapamycin complex 1 and can activate lipogenic gene expression via distinct pathways.

Though calorically equivalent to glucose, fructose appears to be more lipogenic, leading to dyslipidemia, fatty liver disease, cardiovascular disease, and diabetes. To better understand how fructose induces lipogenesis, we compared the effects of fructose and glucose on the mTORC1 signaling node, a central regulator of lipogenesis. We found that fructose acutely and transiently suppressed mTORC1 signaling in vitro and in vivo. The constitutive activation of mTORC1 reduced hepatic lipogenic gene expression a...

Low expression of IL-18 and IL-18 receptor in human skeletal muscle is associated with systemic and intramuscular lipid metabolism-Role of HIV lipodystrophy.

Interleukin (IL)-18 is involved in regulation of lipid and glucose metabolism. Mice lacking whole-body IL-18 signalling are prone to develop weight gain and insulin resistance, a phenotype which is associated with impaired fat oxidation and ectopic skeletal muscle lipid deposition. IL-18 mRNA is expressed in human skeletal muscle but a role for IL-18 in muscle has not been identified. Patients with HIV-infection and lipodystrophy (LD) are characterized by lipid and glucose disturbances and increased levels ...

Fructose metabolism, cardiometabolic risk, and the epidemic of coronary artery disease.

Despite strong indications that increased consumption of added sugars correlates with greater risks of developing cardiometabolic syndrome (CMS) and cardiovascular disease (CVD), independent of the caloric intake, the worldwide sugar consumption remains high. In considering the negative health impact of overconsumption of dietary sugars, increased attention is recently being given to the role of the fructose component of high-sugar foods in driving CMS. The primary organs capable of metabolizing fructose in...

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...

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...

Basal Insulin Peglispro Increases Lipid Oxidation, Metabolic Flexibility, Thermogenesis And Ketone Bodies Compared To Insulin Glargine In Subjects With Type 1 Diabetes Mellitus.

When treated with basal insulin peglispro (BIL), patients with type 1 diabetes mellitus (T1DM) exhibit weight loss and lower prandial insulin requirements versus insulin glargine (GL), while total insulin requirements remain similar. One possible explanation is enhanced lipid oxidation and improved ability to switch between glucose and lipid metabolism with BIL. This study compared the effects of BIL and GL on glucose and lipid metabolism in subjects with T1DM.

Effectiveness of a bioactive food compound in anthropometric measures of individuals with HIV/AIDS: A nonrandomized trial.

Highly Active Antiretroviral therapy (HAART) promotes anthropometric changes in lipid metabolism and glucose in patients with Human Immunodeficiency Virus (HIV). Functional foods play an important role on metabolism. Bioactive Food Compound (BFC) has shown effective results in changes arising from decompensated lipid metabolism due to the effects of HAART on HIV patients. From this perspective, the objective of this study is to evaluate anthropometric indicators and the body composition of patients undergoi...

Effects of growth hormone on glucose metabolism and insulin resistance in human.

Growth hormone (GH) is important for promotion of somatic growth and the regulation of substrate metabolism. Metabolic action of GH occurs in multiple tissues including the liver, muscle, fat and pancreas either directly or indirectly through insulin-like growth factor 1. The diabetogenic action of GH has been well-described in previous in vivo studies. In this paper, we review the metabolic effects of GH on peripheral tissues focusing on glucose metabolism and insulin resistance, and discuss results from h...

Chlorogenic acid (CGA): A pharmacological review and call for further research.

Phenolic acids have recently gained substantial attention due to their various practical, biological and pharmacological effects. Chlorogenic Acid (CGA, 3-CQA) is a most abundant isomer among caffeoylquinic acid isomers (3-, 4-, and 5-CQA), that currently known as 5-CQA as per guidelines of IUPAC. It is one of the most available acids among phenolic acid compounds which can be naturally found in green coffee extracts and tea. CGA is an important and biologically active dietary polyphenol, playing several im...

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...

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...

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.

Dietary and Endogenous Sphingolipid Metabolism in Chronic Inflammation.

Chronic inflammation is a common underlying factor in many major metabolic diseases afflicting Western societies. Sphingolipid metabolism is pivotal in the regulation of inflammatory signaling pathways. The regulation of sphingolipid metabolism is in turn influenced by inflammatory pathways. In this review, we provide an overview of sphingolipid metabolism in mammalian cells, including a description of sphingolipid structure, biosynthesis, turnover, and role in inflammatory signaling. Sphingolipid metabolit...

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 ...

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...

Fluctuations of extracellular glucose and lactate in the mouse primary visual cortex during visual stimulation.

We measured the extracellular glucose and lactate in the primary visual cortex in the CD-1 mouse using electrochemical electrodes. To gain some additional information on brain metabolism, we examined the impact of systemic injections of lactate and fructose on the brain extracellular glucose and lactate changes observed during visual stimulation. We found that simple stimulation using a flashlight produced a decrease in visual cortex extracellular glucose and an increase in extracellular lactate. Similar re...
