Quantitative characterization of 13C-labeled metabolites is an important part of the stable isotope tracing method widely used in metabolic flux analysis. Due to long relaxation time and low sensitivity of 13C nuclei, direct measurement of 13C labeled metabolites using one dimensional 13C NMR often fails to meet the demand of metabolomics studies especially with large number of samples and metabolites having low abundance. Although HSQC-based 2D NMR methods have improved sensitivity with inversion detection, they are time-consuming thus unsuitable for high-throughput absolute quantification of 13C-labeled metabolites...

AIMS: To investigate the roles of salt inducible kinase (SIK1) in high glucose-induced triglyceride accumulation in human hepatoma HepG2 cells as well as in the molecular mechanism by which metformin, a drug to treat diabetes, suppresses high glucose-induced lipogenesis. MAIN METHODS: A cell model for high glucose-induced hepatic steatosis was prepared by exposing HepG2 cells to high glucose (25mmol) in the absence or presence of metformin (0.5mmol). Intracellular triglycerides were visualized by Oil Red O and measured using a triglyceride assay kit...

BACKGROUND/OBJECTIVE: Many controversies regarding the association of liver miRNAs with obesity and nonalcoholic fatty liver diseases (NAFLD) call for additional validations. This study sought to investigate variations in genes and hepatic miRNAs in a sample of obese patients with or without NAFLD and human hepatocytes. SUBJECTS/METHODS: Sixty non-consecutive obese women following bariatric surgery were recruited. Subjects were classified as NAFLD (n=17), borderline (n=24), and controls (n=19) with normal enzymatic profile, liver histology, and ultrasound assessments...

Type 2 diabetes (T2D) is manifested by progressive metabolic impairments in tissues such as skeletal muscle and liver, and these tissues become less responsive to insulin, leading to hyperglycemia. In the present study, stimulation of glucose and oleic acid uptake by elderflower extracts, constituents and metabolites were tested in vitro using the HepG2 hepatocellular liver carcinoma cell line and human skeletal muscle cells. Among the crude extracts, the 96% EtOH extract showed the highest increase in glucose and oleic acid uptake in human skeletal muscle cells and HepG2-cells...

OBJECTIVES: Diabetes mellitus is a common metabolic disorder with high global prevalence. It is characterized by a decrease in insulin secretion or a decrease in insulin sensitivity or both. The aim of the present study was to investigate the effects of resveratrol treatment on the expression of the genes involved in insulin signalling cascade, such as Forkhead box protein O1 (FoxO1), 3-phosphoinositide-dependent protein kinase 1 (PDPK1) and mammalian target of rapamycin (mTOR). METHODS: HepG2 cells were cultured in serum-free medium with high concentrations of glucose and insulin and then were treated with resveratrol (5, 10 and 20 µM) for 24 and 48 hours...

Several previous studies have shown the benefits of deep sea water (DSW) in lipid metabolism. However, the effects of DSW on cellular cholesterol accumulation and synthesis induced by high glucose or free fatty acid plus high glucose [4.5g/L] (FFA/glucose) have not been fully elucidated to date. Herein, we showed the effects of mineral-balanced DSW [magnesium (Mg):calcium (Ca)=3:1] (MB-DSW) on cholesterol metabolism induced by high glucose or FFA/glucose in HepG2 hepatic cells. Moreover, the effects of high ratio Mg DSW [Mg:Ca=40:1] (Mg40) were also investigated...

Although the enzymatic activity of isocitrate dehydrogenase 1 (IDH1) was defined decades ago, its functions in vivo are not yet fully understood. Cytosolic IDH1 converts isocitrate to α-ketoglutarate (α-KG), a key metabolite regulating nitrogen homeostasis in catabolic pathways. It was thought that IDH1 might enhance lipid biosynthesis in liver or adipose tissue by generating NADPH, but we show here that lipid contents are relatively unchanged in both IDH1-null mouse liver and IDH1-deficient HepG2 cells generated using the CRISPR-Cas9 system...

Oxidative stress and diabetes have a tendency to alter protein, lipid, and DNA moieties. One of the strategic methods used to reduce diabetes-associated oxidative stress is to inhibit the carbohydrate-digesting enzymes, thereby decreasing gastrointestinal glucose production. Plant-derived natural antioxidant molecules are considered a therapeutic tool in the treatment of oxidative stress and diabetes. The objective of this study was to identify tartary buckwheat rice flavonoids and evaluate the effect of in vitro digestion on their antioxidant and antidiabetic properties...

In this study, we report that daily administration of luteolin for 8 weeks improved hepatic steatosis by repressing hepatic TG accumulation and increasing glycogen storage. Luteolin inhibited hepatic de novo lipid synthesis by regulating the LXR-SREBP-1c signaling pathway, which is over-activated in the livers of db/db mice. Further in vitro studies revealed that luteolin can competitively bind to the ligand binding domain to suppress the LXR activation induced by an LXR agonist and high glucose, thereby decreasing TG accumulation in HepG2 cells and primary hepatocytes...

Peroxisome proliferator-activated receptor γ (PPARγ) is recognized as a key regulator of insulin resistance. In this study, we searched for novel PPARγ agonists in a library of structurally diverse organic compounds and determined that podophyllotoxin exhibits partial agonist activity toward PPARγ. Eight novel podophyllotoxin-like derivatives were synthesized and assayed for toxicity and functional activity toward PPARγ to reduce the possible systemic toxic effects of podophyllotoxin and to maintain partial agonist activity toward PPARγ...

Prunin is the main flavonoid in Prunus davidiana stems and improves hyperglycemia and hyperlipidemia in streptozotocin-induced diabetic rats. The aim of this study was to investigate the in vitro anti-diabetic potential of prunin via the inhibition of protein tyrosine phosphatase 1B (PTP1B), α-glucosidase, peroxynitrite (ONOO(-))-mediated tyrosine nitration, and stimulation of glucose uptake in insulin-resistant hepatocytes. In addition, a molecular docking simulation was performed to predict specific prunin binding modes during PTP1B inhibition...

Dihydromyricetin (DMY), an important flavanone found in Ampelopsis grossedentata, possesses antioxidative properties that ameliorate skeletal muscle insulin sensitivity and exert a hepatoprotective effect. However, little is known about the effects of DMY in the context of high-fat diet (HFD)-induced hepatic insulin resistance. Male Sprague-Dawley(SD) rats were fed a HFD(60% fat) supplemented with DMY for 8 weeks. The administration of DMY to the rats with HFD-induced insulin resistance reduces hyperglycemia, plasma levels of insulin, and steatosis in the liver...

This study reports the characterization and antiproliferative activity of exopolysaccharides (EPS) produced by submerged cultures of the endophytes Diaporthe sp. JF766998 and Diaporthe sp. JF767007 isolated from the medicinal plant Piper hispidum Sw. Both strains secreted a crude EPS that, upon size exclusion chromatography, showed to contain a heteropolysaccharide (galactose, glucose and mannose) and a high-molecular weight glucan. Data from methylation analysis, FTIR and NMR spectroscopy ((1)H, COSY, TOCSY and HSQC-DEPT) indicated that the purified glucan consisted of a main chain of glucopyranosyl β-(1→3) linkages substituted at O-6 by glucosyl residues...

AIMS/HYPOTHESIS: Soluble insulin receptor (sIR), the ectodomain of the insulin receptor (IR), has been detected in human plasma and its concentration paralleled that of blood glucose. We have previously developed an in vitro model using HepG2 liver-derived cells, which mimics changes in sIR levels in plasma from diabetic patients and shows that calcium-dependent proteases cleave IR extracellularly (a process known as shedding). The present study aimed to reveal the mechanisms of IR cleavage...

Impaired insulin signaling and the associated insulin-resistance in liver, adipose tissue, and skeletal muscle, represents a hallmark of the pathogenesis of type 2-diabetes-mellitus. Here we show that in the liver of db/db mice, a murine model of obesity, type 2 diabetes, and dyslipidemia, the elevated activities of mitogen-activated protein kinases (MAPK; ERK1/2 and p38(MAPK)), and Akt/PKB are abolished by rosiglitazone-treatment, which normalizes blood glucose in db/db mice. This is unequivocal evidence of a functional link between the activation of the MAPK specific inflammatory-pathway and high-blood sugar...

Nasturtium (Tropaeolum majus L.) contains high concentrations of benzylglcosinolate. We found that a hydrolysis product of benzyl glucosinolate-the benzyl isothiocyanate (BITC)-modulates the intracellular localization of the transcription factor Forkhead box O 1 (FOXO1). FoxO transcription factors can antagonize insulin effects and trigger a variety of cellular processes involved in tumor suppression, longevity, development and metabolism. The current study evaluated the ability of BITC-extracted as intact glucosinolate from nasturtium and hydrolyzed with myrosinase-to modulate i) the insulin-signaling pathway, ii) the intracellular localization of FOXO1 and, iii) the expression of proteins involved in gluconeogenesis, antioxidant response and detoxification...

BACKGROUND/AIMS: Liver X receptor (LXR), a member of the nuclear receptor superfamily, is known to induce the expression of SREBP-1c and ChREBP, two master regulators of hepatic lipogenesis. Histone deacyetylases (HDACs) have been shown to play critical roles in glucose and lipids metabolism. However, the exact role of HDAC5 in lipogenesis remains elusive. METHODS: mRNA and protein levels of HDAC5 were analyzed by quantitative real-time PCR and Western blots in high-fat-diet-induced and leptin receptor deficiency-induced obese mice...

This study evaluated the capacity of mulberry anthocyanin extract (MAE) on insulin resistance amelioration in HepG2 cells induced by high glucose and palmitic acid and diabetes-related metabolic changes in type 2 diabetic mice. In vitro, MAE alleviated insulin resistance in HepG2 cells and increased glucose consumption, glucose uptake and glycogen content. Enzyme activities of phosphoenolpyruvate carboxykinase (PEPCK) and glucose-6-phosphatase (G6Pase) were decreased due to PPARγ coactivator 1α (PGC-1α) and forkhead box protein O1 (FOXO1) inhibition...

Diet-induced obesity is a major contributing factor to the progression of hepatic insulin resistance. Increased free fatty acids in liver enhances endoplasmic reticulum (ER) stress and production of reactive oxygen species (ROS), both are directly responsible for dysregulation of hepatic insulin signaling. BI-1, a recently studied ER stress regulator, was examined to investigate its association with ER stress and ROS in insulin resistance models. To induce obesity and insulin resistance, BI-1 wild type and BI-1 knock-out mice were fed a high-fat diet for 8 weeks...
