Scutellaria baicalensis has been reported to improve the lipid metabolism of high-fat diet-induced liver dysfunction, but direct evidence is rare. This study aimed to explore the effects and mechanisms of S. baicalensis and its major constituent baicalin on hepatic lipotoxicity. KK-Ay mice and orotic acid (OA)-induced nonalcoholic fatty liver disease (NAFLD) rats were used to evaluate lipid metabolism regulatory effects. Sodium oleate-induced triglyceride-accumulated HepG2 cells were used for the mechanism study, pretreated with or without compound C or STO-609 or transfected with liver kinase B1 (LKB1) siRNA...

BACKGROUND: Recent evidence supports that the gut microbiota may be involved in the pathophysiology of non-alcoholic fatty liver disease (NAFLD), and may also offer avenues for treatment or prevention. METHODS: We investigated the associations among gut microbiota, diet and hepatic fat fraction (HFF) in 107 adolescents. Magnetic Resonance Imaging (MRI) was used to assess HFF, and 16S rRNA gene sequencing was performed on collected fecal samples. Dietary intake was assessed using Food Frequency Questionnaires...

Metabolic disorders, including obesity, non-alcoholic fatty liver disease (NAFLD), metabolic syndrome and diabetes, are complex and progressive diseases. Enoyl coenzyme A hydratase 1 (Ech1) is an enzyme that participates in mitochondrial fatty acid β-oxidation; however, little is known regarding the significance of Ech1 in the pathogenesis of metabolic disorders. Here, we report that high-fat-diet (HFD)-induced and genetic obesity could increase Ech1 expression in mouse liver. The overexpression of Ech1 using adeno-associated virus (AAV2/8) ameliorated HFD-induced liver lipid accumulation and accompanying liver injury...

Increasing prevalence of non-alcoholic fatty liver disease (NAFLD) worldwide has necessitated a more thorough understanding of it and expanded the scope of research in this field. Women are more resistant to NAFLD than men despite equal exposure to major risk factors, such as obesity or hyperlipidemia. Female resistance is hormone-dependent, as evidenced by the sharp increase in NAFLD incidence in post-menopausal women who do not take hormone replacement therapy. Here, we found that the estrogen-responsive pituitary hormone prolactin (PRL), through specific PRL receptor (PRLR), down-regulates hepatic triglyceride (TG) accumulation...

Nonalcoholic fatty liver disease (NAFLD) is a kind of liver lipid synthesis and degradation imbalance related with metabolic syndrome. Celecoxib shows the function of ameliorating NAFLD, but the underlying mechanisms remain unknown. Here, we discuss the possible mechanisms of celecoxib alleviating NAFLD by restoring autophagic flux. Lipids were accumulated in L02 cells treated with palmitate as well as SD rats fed with high-fat diet. Western blot showed that LC3 II/I was higher and p62 was lower on the early stage of steatosis while on the late stage both of them were higher, indicating that autophagic flux was activated on the early stage of steatosis, but blocked on the late stage...

Excess lipid accumulation is an early signature of nonalcoholic fatty liver disease (NAFLD). Although liver receptor homolog 1 (LRH-1) (encoded by NR5A2) is suppressed in human NAFLD, evidence linking this phospholipid-bound nuclear receptor to hepatic lipid metabolism is lacking. Here, we report an essential role for LRH-1 in hepatic lipid storage and phospholipid composition based on an acute hepatic KO of LRH-1 in adult mice (LRH-1AAV8-Cre mice). Indeed, LRH-1-deficient hepatocytes exhibited large cytosolic lipid droplets and increased triglycerides (TGs)...

NOD-like receptor (NLR)X1 (NLRX1) is an ubiquitously expressed inflammasome-independent NLR that is uniquely localized in mitochondria with as yet unknown effects on metabolic diseases. Here, we report that NLRX1 is essential in regulating cellular metabolism in non-immune parenchymal hepatocytes by decreasing mitochondrial fatty acid-dependent oxidative phosphorylation (OXPHOS) and promoting glycolysis. NLRX1 loss in mice has a profound impact on the prevention of diet-induced metabolic syndrome parameters, non-alcoholic fatty liver disease (NAFLD) progression, and renal dysfunction...

Pioglitazone (PIO) has been reported to be effective for nonalcoholic fatty liver disease (NAFLD) and alogliptin (ALO) may have efficacy against NAFLD progression in patients with type 2 diabetes mellitus (T2DM). The present study examined the effectiveness of ALO in a rodent model of NAFLD and diabetes mellitus. KK‑Ay mice were used to produce an NAFLD model via administration of a choline‑deficient (CD) diet. To examine the effects of alogliptin, KK‑Ay mice were provided with a CD diet with 0.03% ALO and/or 0...

SCOPE: Non-alcoholic fatty liver disease (NAFLD) is a common disease that is concomitant with obesity, resulting in increased mortality. To date, the efficiency of NAFLD treatment still needs to be improved. Therefore, we aimed to evaluate the effect of Lactobacillus mali APS1, which was isolated from sugary kefir, on hepatic steatosis in rats fed a high-fat diet (HFD). METHODS AND RESULTS: Sprague Dawley rats were fed a control diet, a high-fat diet with saline and a high-fat diet with APS1 intervention by gavage daily for 12 weeks...

Vinyl chloride (VC), a common industrial organochlorine and environmental pollutant, has been shown to directly cause hepatic angiosarcoma and toxicant-associated steatohepatitis at high exposure levels. However, the impact of lower concentrations of VC on the progression of underlying liver diseases (e.g., nonalcoholic fatty liver disease [NAFLD]) is unclear. Given the high prevalence of NAFLD in the United States (and worldwide) population, this is an important concern. Recent studies by our group with VC metabolites suggest a potential interaction between VC exposure and underlying liver disease to cause enhanced damage...

The incidence of obesity and its metabolic complications are rapidly increasing and become a major public health issue. This trend is associated with an increase in the prevalence of non-alcoholic fatty liver disease (NAFLD), insulin resistance and diabetes. The sequence of events leading to NAFLD progression and mitochondrial dysfunction and their interrelation remains to be elucidated. This study aimed to explore the installation and progression of NAFLD and its association with the liver mitochondrial structure and activity changes in rats fed an obesogenic diet up to 20 weeks...

AIMS/HYPOTHESIS: Targeting regulators of adipose tissue lipoprotein lipase could enhance adipose lipid clearance, prevent ectopic lipid accumulation and consequently ameliorate insulin resistance and type 2 diabetes. Angiopoietin-like 8 (ANGPTL8) is an insulin-regulated lipoprotein lipase inhibitor strongly expressed in murine adipose tissue. However, Angptl8 knockout mice do not have improved insulin resistance. We hypothesised that pharmacological inhibition, using a second-generation antisense oligonucleotide (ASO) against Angptl8 in adult high-fat-fed rodents, would prevent ectopic lipid accumulation and insulin resistance by promoting adipose lipid uptake...

MetS syndrome (MetS) is a term used to characterize individuals having at least three of the following diseases: obesity, dyslipidemia, hyperglycemia, insulin resistance, hypertension, and non-alcoholic fatty liver disease (NAFLD).  It is widespread and the number of individuals with MetS is increasing.  However, the events leading to the manifestation of MetS are not well understood.  Here, we show that loss of mARV1 in mice results in resistance to acquiring diseases associated with MetS.   Arv1-/- animals fed a high fat diet were resistant to diet-induced obesity, had lower blood cholesterol and triglycerides levels, and retained glucose tolerance and insulin sensitivity...

3,3',4,4',5-pentachlorobiphenyl (PCB126), a dioxin-like PCB, elicits toxicity through a wide array of non-carcinogenic effects, including metabolic syndrome, wasting, and non-alcoholic fatty-liver disease (NAFLD). Previously, we reported decreases in the transcription of several enzymes involved in gluconeogenesis, before the early onset of lipid accumulation. Hence, this study was aimed at understanding the impact of resultant decreases gluconeogenic enzymes on growth, weight and metabolism in the liver, upon extended exposure...

BACKGROUND/AIMS: Recent studies have suggested that changes in non-coding mRNA play a key role in the progression of non-alcoholic fatty liver disease (NAFLD). Metformin is now recommended and effective for the treatment of NAFLD. We hope the current analyses of the non-coding mRNA transcriptome will provide a better presentation of the potential roles of mRNAs and long non-coding RNAs (lncRNAs) that underlie NAFLD and metformin intervention. METHODS: The present study mainly analysed changes in the coding transcriptome and non-coding RNAs after the application of a five-week metformin intervention...

Type II diabetes mellitus (T2DM) is a multifactorial disease involving complex genetic and environmental interactions. No single animal model has so far mirrored all the characteristics or complications of diabetes in humans. Since this disease represents a chronic nutritional insult based on a diet bearing a high glycemic load, the ideal model should recapitulate the underlying dietary issues. Most rodent models have three shortcomings: (1) they are genetically or chemically modified to produce diabetes; (2) unlike humans, most require high-fat feeding; (3) and they take too long to develop diabetes...

Exposure to environmental endocrine disruptors (EEDs) contributes to the pathogenesis of many metabolic disorders. Here, we have analyzed the effect of the EED-nonylphenol (NP) on the promotion of non-alcoholic fatty liver disease (NAFLD) in rats fed high sucrose-high fat diet (HSHFD). Fifty Sprague-Dawley rats were divided into five groups: controls fed a normal diet (C-ND); HSHFD-fed controls (C-HSHFD); and rats fed a HSHFD combined with NP at doses of 0.02 μg/kg/day (NP-L-HSHFD), 0.2 μg/kg/day (NP-M-HSHFD), and 2 μg/kg/day (NP-H-HSHFD)...
