BACKGROUND AND PURPOSE: Morin is a natural occurring flavonoid in many dietary plants and has a wide range of beneficial effects on metabolism; however, the mechanism underlying its action remains elusive. EXPERIMENTAL APPROACH: Reporter assay and the Time-Resolved Fluorescence Resonance Energy Transfer assay were used to identify morin as a dual antagonist of LXRα and LXRβ. High fat-diet mixed with morin (100 mg/100 g diet) was administrated to high-fat diet-induced obese or LXRβ(-/-) mice combining with Western blot and RT-PCR analysis to evaluate the pharmacological effect and mechanism of morin treatment...

We have previously identified flavin-containing monooxygenase 5 (FMO5) as a regulator of metabolic ageing. The aim of the present study was to investigate the role of FMO5 in glucose homeostasis and the impact of diet and gut flora on the phenotype of mice in which the Fmo5 gene has been disrupted (Fmo5(-/-) mice). In comparison with wild-type (WT) counterparts, Fmo5(-/-) mice are resistant to age-related changes in glucose homeostasis and maintain the higher glucose tolerance and insulin sensitivity characteristic of young animals...

BACKGROUND: In 2015, the combination of basal insulin and GLP-1 receptor agonist (RA) was incorporated into the guideline recommendations for type 2 diabetes as an option for the last escalation step. The two antidiabetics to be injected subcutaneously are complementary regarding their respective main effects and limitations. Basal insulin is predominantly active between meals and in the fasting state, whereas the main action of GLP-1 RA consists in preventing an excessive postprandial blood glucose increase...

Traditionally, obesity and its related diseases are considered problems in Western countries. However, in the past two decades, urbanization in many Asian countries has led to sedentary lifestyle and overnutrition, and has set the stage for the epidemic of obesity. This article reviews the epidemiological trend of obesity in Asia with special emphasis on the emerging condition of non-alcoholic fatty liver disease (NAFLD). Currently, the population prevalence of NAFLD in Asia is around 25%, similar to that in many Western countries...

BACKGROUND/OBJECTIVES: Modern lifestyle promotes shifted sleep onset and shifted wake up time between weekdays and weekends, producing a condition termed "social-jet lag." Disrupted sleep promotes increased appetite for carbohydrate and fat-rich food, which in long term leads to overweight, obesity and metabolic syndrome. In order to mimic the human situation we produced an experimental model of social-jet lag (Sj-l). With this model, we explored the link between shifted sleep time with consumption of a cafeteria diet (CafD) and the development of obesity and metabolic syndrome...

BACKGROUND: Peroxisome proliferator-activated receptor gamma (PPARγ) is a member of the nuclear receptor superfamily that functions as a ligand-inducible transcription factor. It regulates glucose and lipid metabolism, immunity, and cellular growth and differentiation. Thiazolidinediones (TZDs) are potent insulin sensitizers that function by activating PPARs, with a high specificity for PPARγ. Due to their ability to preserve pancreatic beta cell function and reduce insulin resistance, TZDs have become one of the most prescribed classes of medications for type 2 diabetes (T2D) since their approval by the US Food and Drug Administration (FDA) and initial use in 1997...

Obesity in many current pre-clinical animal models of obesity and diabetes is mediated by monogenic mutations; these are rarely associated with the development of human obesity. A new mouse model, the FATZO mouse, has been developed to provide polygenic obesity and a metabolic pattern of hyperglycemia and hyperinsulinemia, that support the presence of insulin resistance similar to metabolic disease in patients with insulin resistance/type 2 diabetes. The FATZO mouse resulted from a cross of C57BL/6J and AKR/J mice followed by selective inbreeding for obesity, increased insulin and hyperglycemia...

Low glycaemic index (LGI) diets are often reported to benefit metabolic health, but the mechanism(s) responsible are not clear. This review aimed to systematically identify studies investigating metabolic effects of high glycaemic index (HGI) versus LGI diets in mice and rats. A meta-analysis was conducted to calculate an overall effect size, Hedge's standardised mean differences (hereafter d), for each trait, with moderator variables considered in subsequent meta-regressions. Across 30 articles, a HGI diet increased five of the seven traits examined: body weight (d = 0...

Background: Early nutritional interventions may modulate health risks in preterm-born infants. Previously, we showed that preterm-born infants fed an isocaloric protein- and mineral-enriched postdischarge formula (PDF) from term age to 6-mo corrected age (CA) gained more lean mass than did those fed term formula (TF). Long-term follow-up of randomized nutritional trials is important to test the hypothesis that short-term positive effects on health are sustainable.Objective: The aim of this follow-up study was to compare body size, body composition, and metabolic health at age 8 y in preterm-born children who were randomly assigned to receive either PDF or TF from term age until 6-mo CA...

There is a growing and alarming prevalence of obesity and the metabolic syndrome in type I diabetic patients (T1DM), particularly in adolescence. In general, low bone mass, higher fracture risk and increased marrow adipose tissue (MAT) are features of diabetic osteopathy in insulin deficient subjects. On the other hand, type 2 diabetes (T2DM) is associated with normal or high bone mass, a greater risk of peripheral fractures and no change in MAT. Therefore, we sought to determine the effect of weight gain on bone turnover in insulin deficient mice...

BACKGROUND: Weight gain is associated with deterioration in metabolic health, whereas weight loss improves insulin sensitivity. This study assesses the impact of long-term, successfully maintained weight loss and weight-loss relapse on measures of insulin sensitivity and identifies factors that explain variability in insulin sensitivity. METHODS: Women (20-45 years) were recruited into four groups: reduced-overweight/obese (RED, n=15); body mass index (BMI)-matched controls (stable low-weight, n=19), BMI⩽27 kg m(-2); relapsed-overweight/obese subjects (REL, n=11); and BMI-matched controls (obese stable weight, n=11), BMI⩾27 kg m(-2)...

Our previous studies have demonstrated that prenatal caffeine exposure (PCE) induced an intrauterine programming of hypothalamic-pituitary-adrenal axis (HPAA)-associated neuroendocrine metabolism in 3-month-old offspring rats. In this study, we aimed to confirm this programming disorder and high susceptibility to metabolic syndrome (MS) in 10-month-old female PCE offspring with postnatal catch-up growth. We found that PCE female offspring rats showed decreased bodyweight but a higher rate of weight gain after birth...

This study evaluated the effect of Yucca schidigera (YS) extract on the physiological, reproductive, and endocrine indexes of New Zealand White rabbit does. Six-week-old rabbit does were fed a standard diet (control group) or a diet enriched with 5 or 20g of Y powder extract per 100-kg feed mixture for 350days. The does were artificially inseminated after induction of superovulation. Weight gain; conception and kindling rate; viability of pups and mothers; histopathological state of liver and muscle; plasma levels of progesterone (P4), oxytocin (OT), and prostaglandin F (PGF); and the release of P4, insulin-like growth factor I (IGF-I), OT, and PGF by isolated ovarian fragments and their response to the addition of benzene were analyzed...

Adjuvant-induced arthritis in rats decreases body weight and muscle mass. Melanocyte stimulating hormone administration to arthritic rats decreases inflammation and skeletal muscle wasting. In this study, we investigate whether activation of melanocortin-4 receptor by RO27-3225 administration is able to prevent the effect of arthritis on the expression of muscle-specific E3 ubiquitin ligases and MyoD in two different muscles, gastrocnemius (a mainly fast type muscle) and soleus (slow type). Arthritis was induced in male Wistar rats by intradermal injection of Freund's adjuvant...

The underlying mechanism by which MyD88 regulates the development of obesity, metainflammation, and insulin resistance (IR) remains unknown. Global deletion of MyD88 in high-fat diet (HFD)-fed mice resulted in increased weight gain, impaired glucose homeostasis, elevated Dectin-1 expression in adipose tissue (AT), and proinflammatory CD11c+ AT macrophages (ATMs). Dectin-1 KO mice were protected from diet-induced obesity (DIO) and IR and had reduced CD11c+ AT macrophages. Dectin-1 antagonist improved glucose homeostasis and decreased CD11c+ AT macrophages in chow- and HFD-fed MyD88 KO mice...
