Western diet (WD), rich in saturated fat and sugars, has become a risk factor for obesity and metabolic syndrome, however, its effect on endothelial function and vascular remodeling is not fully elucidated. Recent evidence suggests cross-talk between Rho kinase (ROCK) pathway and cardiovascular system. We aimed to investigate the effect of WD on aortic remodeling and the contribution of ROCK signaling. Eight week old male Sprague-Dawley rats were fed either standard chow diet (SD) or high fructose/ high-fat diet, typically as in WD...

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 fructose administration...

S -Allyl cysteine (SAC) is found in garlic and has been reported to exert antidiabetic and antiobesity properties in drug-induced adult experimental models of metabolic dysfunction, but its potential beneficial effects in high-fructose diet neonatal rat models have not been determined. This study investigated the potential prophylactic effects of SAC in high-fructose diet fed suckling rat pups modelling human neonates fed a high-fructose diet. Four-day-old male (n=32) and female (n=32) Wistar rat pups, were randomly assigned to and administered the following treatment regimens daily for 15 days: group I, distilled water; group II, 20% fructose solution (FS); group III, SAC; group IV, SAC+FS...

The study aimed to evaluate the consequences of the consumption of a high-fructose diet (HFR; fructose was responsible for 45% of the energy from carbohydrates) by the mother, the father, or both on C57BL/6 adult male offspring. Non-consanguineous parents received the diet (HFR or control, C) from 8 weeks before mating until weaning (n=10 fathers and n=10 mothers on each diet). After weaning, only the C diet was offered to offspring. The groups were formed by one male randomly taken from each litter. The offspring groups were identified according to the mother's diet (the first letter), then the father's diet (the second letter), that is, C/C, C/HFR, HFR/C, HFR/HFR (n=10 per group)...

Non-alcoholic fatty liver disease (NAFLD)-like conditions enhance the production and action of clotting factors in humans. However, studies examining the effect of NAFLD due to high-fat high-fructose (HFHF) diet in factor VIII-deficient (haemophilia A) animals or patients have not been reported previously. In this study, we investigated the individual role of factor VIII in the progression of diet-induced NAFLD in the factor 8-/- (F8-/- ) mouse model system and its consequences on the haemophilic status of the mice...

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 effects in blood serum than the DE extract...

Widespread consumption of a Western diet, comprised of highly refined carbohydrates and fat, may play a role in the epidemic of hypertension. Hypertension can take origin from early life. Metformin is the preferred treatment for type 2 diabetes. We examined whether prenatal metformin therapy can prevent maternal high-fructose plus post-weaning high-fat diets-induced hypertension of developmental origins via regulation of nutrient sensing signals, uric acid, oxidative stress, and the nitric oxide (NO) pathway...

Objectives/Aims: Fruit is often advocated as a healthy source of nutrients and vitamins. However, the high contents of sugars in many fruits could potentially counteract positive effects on the teeth. Materials and methods: We recruited 30 healthy non-obese participants who were randomised to either supplement their diet with extra fruits or nuts, each at +7 kcal/kg body weight/day, for 2 months. Results: Fructose intake increased from 9...

The increase in fructose consumption in the last decades has an important correlation with the growth of overweight population. Fructose is a monosaccharide found in fruits, vegetables and honey, however, it is widely used in processed food and beverages such as sweeteners. This monosaccharide is metabolized in the liver, so it can produce glucose, lactate, triglycerides, free fatty acids and uric acid, which are responsible for negative effects on the liver and extrahepatic tissues. One effect of the high consumption of fructose is the resistance to Insulin, which appears to be an important issue in the development of metabolic abnormalities observed in animals that were subjected to a high fructose diet...

Hypothalamic inflammation and apoptosis cause neural injury, playing an important role in metabolic syndrome development. Nuclear Factors of Activated T cells (NFATc3) show many physiological and pathological effects. However, the function of NFATc3 in high fat diet (HFD)-induced hypothalamus injury remains unknown. The wild type (WT) and NFATc3-knockout (KO) mice were subjected to HFD feeding for 16 weeks to examine NFATc3 function in vivo. Astrocytes isolated from WT or KO mice were cultured and exposed to fructose (Fru) in vitro...

There is growing evidence that intakes of high-fructose corn syrup (HFCS), HFCS-sweetened soda, fruit drinks and apple juice - a high-fructose 100 % juice - are associated with asthma, possibly because of the high fructose:glucose ratios and underlying fructose malabsorption, which may contribute to enteral formation of pro-inflammatory advanced glycation end products, which bind receptors that are mediators of asthma. Cox proportional hazards models were used to assess associations between intakes of these beverages and asthma risk, with data from the Framingham Offspring Cohort...

Many studies have reported the causes of obese metabolic syndrome (MS); however, the causes of nonobese MS (NMS) remain unknown. In this study, we demonstrated that inflamed dysfunctional adipose tissue plays a crucial role in cholesterol-induced NMS. Control (C), high cholesterol (HC), and HC with 10% fructose in drinking water (HCF) diets were fed to Sprague-Dawley rats for 12 weeks. After 12 weeks, the body weights of the C- and HC-fed rats were comparable, but the weights of the HCF-fed rats were relatively low...

Endoplasmic reticulum (ER), a dynamic organelle, plays an essential role in organizing the signaling pathways involved in cellular adaptation, resilience, and survival. Impairment in the functions of ER occurs in a variety of nutritive disorders including obesity and type 2 diabetes. Here, we hypothesize that (scopoletin) SPL, a coumarin, has the potential to alleviate ER stress induced in vitro and in vivo models by lipotoxicity. To test this hypothesis, the ability of SPL to restore the levels of proteins of ER stress was analyzed...

BACKGROUND AND AIMS: Although the majority of patients with nonalcoholic fatty liver disease (NAFLD) have only steatosis without progression, a sizable fraction develop non-alcoholic steatohepatitis (NASH), which can lead to cirrhosis and hepatocellular carcinoma (HCC). Many established diet-induced mouse models for NASH require 24-52 weeks, which makes testing for drug response costly and time consuming. METHODS: We have sought to establish a murine NASH model with rapid progression of extensive fibrosis and HCC by using a western diet (WD), which is high-fat, high-fructose and high-cholesterol, combined with low dose weekly intraperitoneal carbon tetrachloride (CCl4 ), which served as an accelerator...

Fructose, the most important functional food additive from the last century, has been widely used in industry, agriculture, light industry, food and medicine. With the improvement of people's living standard and economic level, excess intake of fructose results in metabolic symptoms, including hyperleptinemia, insulin resistance and neuroinflammation is causing high risk of chronic kidney disease development in humans and animals. However, the underlying molecular mechanism of renal injury is still not fully understood, and the development of effective drugs and treatments are delayed...

Background & Aims: Nonalcoholic steatohepatitis (NASH) is associated with oxidative stress. We surmised that pharmacologic activation of NF-E2 p45-related factor 2 (Nrf2) using the acetylenic tricyclic bis(cyano enone) TBE-31 would suppress NASH because Nrf2 is a transcriptional master regulator of intracellular redox homeostasis. Methods: Nrf2 +/+ and Nrf2 -/- C57BL/6 mice were fed a high-fat plus fructose (HFFr) or regular chow diet for 16 weeks or 30 weeks, and then treated for the final 6 weeks, while still being fed the same HFFr or regular chow diets, with either TBE-31 or dimethyl sulfoxide vehicle control...

Recent data indicate that artificial sweeteners (AS) may have deleterious effects on glucose metabolism. The purpose of this study was to compare the effects of AS and the effects of a high fructose diet (HFrD) on glucose metabolism and insulin resistance (IR) in Sprague-Dawley (SD) rats. SD rats were fed either regular chow, chow with saccharin (Sac) (0.1 mg/mL) placed in their water, or HFrD for seven weeks. Glucose, insulin, and triglycerides (Tg) levels were measured upon completion. A homeostatic model assessment (HOMA)-IR index was used to determine insulin resistance...

The metabolism of cancer cells is highly plastic. Cancer cells can change their preference for nutrient uptake under nutrient stress. Fructose is one of the most common carbohydrates in diet and its metabolism is also involved in the development and progression of tumors. GLUT5, encoded by SLC2A5 , is the specific fructose transporter in mammalian cells. In this study, we found that SLC2A5 is significantly upregulated in lung adenocarcinoma (LUAD) patients and overexpression of SLC2A5 is highly correlated with poor prognosis of LUAD patients...

BACKGROUND: The gut microbiome plays a critical role in the onset and progression of obesity and the metabolic syndrome. However, it is not well documented whether the cecal versus the fecal microbiome is more relevant when assessing its contribution to these diseases. Here, we amplified the V4 region of the 16S rRNA gene from cecal and fecal samples of female Ossabaw swine fed a low fat control diet (10.5% fat; n=4) or Western diet (43.0% fat; 17.8% high fructose corn syrup; 2% cholesterol; n=3) for 36 weeks...
