Previous studies suggest that the lipid-lowering effect of BBR involves actions on the LDL receptor and the AMPK signaling pathways. However, the implication of these mechanisms is unclear because of the low bioavailability of BBR. Because the main action site of BBR is the gut and intestinal FXR plays a pivotal role in the regulation of lipid metabolism, we hypothesized that the effects of BBR on intestinal FXR signaling pathway might account for its pharmacological effectiveness. Using wild type (WT) and intestine-specific FXR knockout (FXRint-/-) mice, we found that BBR prevented the development of high-fat-diet induced obesity and ameliorated triglyceride accumulation in livers of WT, but not FXRint-/- mice...

OBJECTIVES: Obesity is a major risk factor for endometrial cancer. We evaluated whether obesity exacerbates progression of endometrial hyperplasia (EH) using the PRCre/+ PTENflox/+ mouse model and examined if the type 2 diabetes drug, metformin, could prevent EH. METHODS: Twenty obese (PRCre/+ PTENflox/+) mice were maintained on a high-fat diet, while 20 lean mice ate a matching low-fat diet. Ten mice from each group received metformin (1,000 mg/day) in drinking water...

BACKGROUND: Although Fenofibrate (FF) is a hypolipedmic drug and one of the PPARα agonists which is a drug target for non alcoholic liver disease (NAFLD), no studies had investigated its potential hepatic effects in such cases. AIM: To compare between the effect of FF and Gemfibrozil (GF) on the prognosis of NAFLD in rats. METHODS: Sixty four rats were used and classified into two main groups. Group I (treated for 6 weeks): naïve, FF, GF groups and Group II (treated for 14 weeks and drugs were added at the last 6 weeks): Control, high fat diet (HFD) untreated, HFD+FF, HFD+FF+folic acid (FA) and HFD+GF groups...

The aim of the present study was to identify transcriptional modifications and regulatory networks accounting for physiological and metabolic responses to specific nutrients in the liver of young Belgian Blue × Holstein bulls using RNA-sequencing. A larger trial has been carried out in which animals were fed with different diets: 1] a conventional diet; 2] a low-protein/low-mineral diet (low-impact diet) and 3] a diet enriched in n-3 fatty acids (FAs), conjugated linoleic acid (CLA) and vitamin E (nutraceutical diet)...

BACKGROUND: We previously identified peritoneal B1a cells that secrete natural IgM as a key atheroprotective B cell subset. However, the molecules that activate atheroprotective B1a cells are unknown. Here, we investigated whether Toll-like receptors (TLRs) TLR2, TLR4, and TLR9 expressed by B1a cells are required for IgM-mediated atheroprotection. METHODS AND RESULTS: We adoptively transferred B1a cells from wild-type mice or from mice deficient in TLR2, TLR4, TLR9, or myeloid differentiation primary response 88 (MyD88) into ApoE(-/-) mice depleted of peritoneal B1a cells by splenectomy and fed a high-fat diet for 8 weeks...

Glucocorticoids (GCs) are steroid hormones, naturally produced by activation of the hypothalamic-pituitary-adrenal (HPA) axis, that mediate the immune and metabolic systems. Synthetic GCs are used to treat a number of inflammatory conditions and diseases including lupus and rheumatoid arthritis. Generally, chronic or high dose GC administration is associated with side effects such as steroid-induced skeletal muscle loss, visceral adiposity, and diabetes development. Patients who are taking exogenous GCs could also be more susceptible to poor food choices, but the effect that increasing fat consumption in combination with elevated exogenous GCs has only recently been investigated...

Over activity of cannabinoid receptor type 1 (CB1R) plays a key role in increasing the incidence of obesity-induced nonalcoholic fatty liver disease. Tissue proteome analysis has been applied to investigate the bioinformatics regarding the mode of action and therapeutic mechanism. The aim of this study was to explore the potential pathways altered with CB1R in obesity-induced fatty liver. Male C57BL/6 mice were fed either a standard chow diet (STD) or a high-fat diet (HFD) with or without 1-week treatment of CB1R inverse agonist AM251 at 5 mg/kg...

SCOPE: The overproduction of very low density lipoprotein (VLDL) is an important cause for initiation and development of atherosclerosis, which is highly associated with insulin signaling. The aim of this work is to verify whether the inhibition of VLDL overproduction is an underlying mechanism for a Laminaria japonica polysaccharide (LJP61A) to resist atherosclerosis. METHODS AND RESULTS: LJP61A (50 and 200 mg/Kg/day) was orally administered to a high fat diet (HFD)-fed LDLr(-/-) mice for 14 weeks...

SCOPE: The 'Predictive Adaptive Response' hypothesis suggests the in utero environment when mismatched with the post-natal environment can influence later life health. Underlying mechanisms are poorly understood, but may involve gene transcription changes, regulated via epigenetic mechanisms. METHODS AND RESULTS: In a 2 × 2 factorial design, female C57Bl/6 mice were randomised to low or normal folate diets (0.4mg/2mg folic acid/kg diet) prior to and during pregnancy and lactation with offspring randomised to high or low fat diets at weaning...

Epidemiological and animal studies show that deleterious maternal environments predispose aging offspring to metabolic disorders and type 2 diabetes. Young progeny in a rat model of maternal low protein diet (LP) is normoglycemic despite collapsed insulin secretion. However, without further worsening of the insulin secretion defect glucose homeostasis deteriorates in aging LP descendants. Here we report that normoglycemic and insulinopenic 3-month-old LP progeny shows increased body temperature and energy dissipation in association with enhanced brown adipose tissue (BAT) activity...

To identify target energy balance-related behaviors (ERBs), baseline data from 141 overweight or obese schoolchildren (aged 8-14 years old) was used to predict adiposity [body mass index (BMI) and fat percentage] one year later. The ERBs included a modified Dietary Approach to Stop Hypertension diet score (DASH score), leisure-time physical activity (PA, days/week), and leisure screen time (minutes/day). Several cardiometabolic variables were measured in the fasting state, including systolic blood pressure (SBP), diastolic blood pressure (DBP), blood glucose (GLU), total cholesterol (TC), triglycerides (TG), low-density lipoprotein (LDL-C), and high-density lipoprotein (HDL-C)...

Genome-wide association studies have shown that Krüppel-like factor 14 (KLF14) is associated with both Type 2 diabetes mellitus and lipid metabolism. However, its role in chronic inflammatory responses and the pathogenesis of atherosclerosis remains unknown. The present study was designed to investigate both in vivo and in vitro the impact of KLF14 on chronic inflammatory responses and atherosclerosis. ApoE KO mice, a well-established animal model of atherosclerosis, had higher expressions of KLF14 in aorta tissues than that in C57BL/6 J mice when fed the high-fat diet (HFD) or standard chow diet...

BACKGROUND: A major obstacle in using FDG-PET/CT to diagnose cardiac sarcoidosis (CS) is the unpredictable physiological myocardial FDG uptake. We hypothesized that a prolonged 72-hour pretest high-fat, high-protein, and very-low-carbohydrate (HFHPVLC) diet preparation could suppress physiologic myocardial uptake of FDG and thus help to identify active CS. METHODS: This retrospective study included 215 FDG-PET/CT tests from 207 patients with biopsy-proven sarcoidosis and clinical suspicion for CS between July 2014 and December 2015...

The diabetic diet is one of the pillars of diabetes treatment. The rapid development of knowledge relating to the treatment of diabetes also includes diet. The paper focuses on the importance of a diet in the treatment of type 2 diabetes and prevention of atherosclerosis. Its main goal is to assess the impact of a composition of macronutrients on individuals with type 2 diabetes. The paper is divided into several parts, each of which ends with a conclusion. The first part examines weight reduction. The diet aimed at a weight loss is effective, it can effectively prevent diabetes, it leads to improvements in glucose control and reduction of the risk factors for atherosclerosis, however it will not impact on cardiovascular morbidity and mortality until after more than 20 years...

A D Higginson, J M McNamara
BACKGROUND AND OBJECTIVES: Peoples' attempts to lose weight by low calorie diets often result in weight gain because of over-compensatory overeating during lapses. Animals usually respond to a change in food availability by adjusting their foraging effort and altering how much energy reserves they store. But in many situations the long-term availability of food is uncertain, so animals may attempt to estimate it to decide the appropriate level of fat storage. METHODOLOGY: We report the results of a conceptual model of feeding in which the animal knows whether food is currently abundant or limited, but does not know the proportion of time, there will be an abundance in the long-term and has to learn it...

BACKGROUND: Patients with coronary artery disease (CAD) are characterized by an impaired cardiometabolic risk profile including high levels of atherogenic apolipoprotein (apo) B-containing lipoprotein levels. Genetic studies have highlighted a critical role for proprotein convertase subtilisin/kexin type 9 (PCSK9) in lipoprotein metabolism and CAD risk. OBJECTIVE: To determine whether improving dietary quality and increasing physical activity levels improve parameters of the cardiometabolic risk profile such as plasma apoB and PCSK9 levels in patients with CAD...
