BACKGROUND
Obese patients are frequently characterized by insulin resistance and decreased insulin-mediated glycogen synthesis in skeletal muscle. Whether they also have impaired postprandial hepatic glycogen synthesis remains unknown.
OBJECTIVE
To determine whether postprandial hepatic glycogen
OBJECTIVE
The spliced transcription factor Xbp1 (Xbp1s), a transducer of the unfolded protein response (UPR), regulates lipolysis. Lipolysis is stimulated by fasting when uridine synthesis is also activated in adipocytes.
METHODS
Here we have examined the regulatory role Xbp1s in stimulation of
Activation of orexigenic AgRP-expressing neurons in the arcuate nucleus of the hypothalamus potently promotes feeding, thus defining new regulators of AgRP neuron activity could uncover potential novel targets for obesity treatment. Here, we demonstrate that AgRP neurons express the purinergic
Obesity and pregnancy both place the liver under metabolic stress, but interactions between obstetric obesity and bilirubin metabolism have not been studied. We determined associations between obesity, maternal/neonatal bilirubin levels, and uridine 5'diphosphate-glucuronosyltransferase 1A1 (UGT1A1)
Uridine-diphosphate (UDP) and its receptor P2Y6 have recently been identified as regulators of AgRP neurons. UDP promotes feeding via activation of P2Y6 receptors on AgRP neurons, and hypothalamic UDP concentrations are increased in obesity. However, it remained unresolved whether inhibition of P2Y6
NAD+ biosynthesis is an attractive and promising therapeutic target for influencing health span and obesity-related phenotypes as well as tumor growth. Full and effective use of this target for therapeutic benefit requires a complete understanding of NAD+ biosynthetic pathways. Here, we report a
BACKGROUND
Sex steroids are involved in the regulation of pubertal cortical bone expansion in males. In vitro studies have indicated that the enzyme uridine diphosphate glucuronosyltransferase (UGT) 2B7 has the capacity to glucuronidate sex steroids and their metabolites.
OBJECTIVE
Our objective was
1. Glucose 6-phosphate, fructose 6-phosphate, fructose diphosphate, glycerol phosphate and uridine diphosphate glucose have been measured in human adipose tissue and blood from obese subjects under fed and fasting conditions and in obese diabetic and non-diabetic subjects before and after an oral
Carbohydrate and lipid metabolism in the liver has been reported to follow a certain circadian rhythm. Moreover, uridine supplementation also affected glucose and lipid homeostasis in previous studies; however, the mechanisms remain unclear. Therefore, this study was conducted to investigate whether
Binge eating disorder (BED) increasingly affects population, but the mechanisms of the disease and its biomarkers are not well characterized. Recently, plasma purines, pyrimidines, amino acid and nicotinamide metabolites profiling attracted attention in studies on pathology and biomarkers of mental
HSG4112, a racemic drug, is a new anti-obesity agent. In this study, the stereoselective pharmacokinetics of HSG4112 were investigated in rats and dogs, and the underlying mechanism was investigated. The plasma concentrations of HSG4112(S) and HSG4112(R) were quantitated in plasma from rats and
Genetically obese Zucker rats exhibit symptoms similar to those of obese patients with insulin-resistance or Type II diabetes; therefore, they have been used as a genetic model to study obesity, as well as a pharmacological model for the discovery of new drugs for the treatment of Type II diabetes
A previous genome-wide association study (GWAS) on obese/overweight Korean women reported five new genetic loci associated with the basal metabolic rate (BMR) and body mass index (BMI), NRG3, OR8U8, BCL2L2-PABPN1, PABPN1, and SLC22A17. This metabolite GWAS (mGWAS)
Solute uptake into liver plasma membrane vesicles from either lean or obese Zucker rats was monitored. D-Glucose and L-leucine uptakes at physiological concentrations of the substrate were not different in lean and obese Zucker rats. In agreement with a previous report (Ruiz et al. (1991) Biochem.
