Abstract
Genstein is the most abundant phytoestrogen in soybean that was reported to play positive roles in menopausal syndrome and metabolic syndrome. In the present study, we investigated the effects and potential mechanisms of genistein against progression of nonalcoholic fatty liver disease (NAFLD) in BRL cells treated with fatty acid mixture (oleate/palmitate, 2:1 ratio). Our data demonstrated that genistein remarkably improved fatty acid mixture-induced hepatocelluler fat accumulation, inhibited upregulation of genes expression related to fatty acid synthesis, and derepressed those associated with fatty acid oxidation. In addition, the results displayed that genistein promoted the phosphorylation of adenosine monophosphate-activated protein kinase (AMPK) suppressed by fatty acid, which were significantly weakened by compound C, an AMPK inhibitor. Taken all together, genistein is capable to ameliorate fat accumulation through regulation of fatty acid metabolism mediated by AMPK activation in BRL cells. Further investigations are needed to verify the protective effects of genistein on NAFLD model in in vivo animal study or in vitro human cell lines along with absorption, distribution, metabolism, and excretion studies of genistein. PRACTICAL APPLICATION Genistein is able to ameliorate fat accumulation through regulation of fatty acid metabolism mediated by AMPK activation in vitro.

Abstract
UNLABELLED Background & aims. G-allele of PNPLA3 (rs738409) favours triglycerides accumulation and steatosis. In this study, we examined the effect of quercetin and natural extracts from mushroom and artichoke on reducing lipid accumulation in hepatic cells. MATERIAL AND METHODS Huh7.5 cells were exposed to oleic acid (OA) and treated with quercetin and extracts to observe the lipid accumulation, the intracellular-TG concentration and the LD size. Sterol regulatory element binding proteins-1 (SREBP-1), peroxisome proliferator-activated receptor (PPARα-γ) and cholesterol acyltransferase (ACAT) gene expression levels were analysed. RESULTS Quercetin decreased the intracellular lipids, LD size and the levels of intracellular-TG through the down-regulation of SREBP-1c, PPARγ and ACAT1 increasing PPARα. The natural-extracts suppressed OA-induced lipid accumulation and the intracellular-TG. They down-regulate the hepatic lipogenesis through SREBP-1c, besides the activation of lipolysis through the increasing of PPARα expression. CONCLUSIONS Quercetin and the aqueous extracts decrease intracellular lipid accumulation by down-regulation of lipogenesis and up-regulation of lipolysis.

Abstract
Liver disease, involving a wide range of liver pathologies from fatty liver, hepatitis, and fibrosis to cirrhosis and hepatocellular carcinoma, is a serious health problem worldwide. In recent years, many natural foods and herbs with abundant phytochemicals have been proposed as health supplementation for patients with hepatic disorders. As an important category of phytochemicals, natural polyphenols have attracted increasing attention as potential agents for the prevention and treatment of liver diseases. The striking capacities in remitting oxidative stress, lipid metabolism, insulin resistance, and inflammation put polyphenols in the spotlight for the therapies of liver diseases. It has been reported that many polyphenols from a wide range of foods and herbs exert therapeutic effects on liver injuries via complicated mechanisms. Therefore, it is necessary to have a systematical review to sort out current researches to help better understand the potentials of polyphenols in liver diseases. In this review, we aim to summarize and update the existing evidence of natural polyphenols in the treatment of various liver diseases by in vitro, in vivo, and clinical studies, while special attention is paid to the action mechanisms.

Long-term fermented soybean paste improves metabolic parameters associated with non-alcoholic fatty liver disease and insulin resistance in high-fat diet-induced obese mice.

Abstract
Recently, Korean traditional fermented soybean paste, called Doenjang, has attracted attention for its protective effect against diet-related chronic diseases such as obesity and type 2 diabetes. Long-term fermented soybean pastes (LFSPs) are made by fermentation with naturally-occurring microorganisms for several months, whereas short-term fermented soybean pastes (SFSPs) are produced by shorter-time fermentation inoculated with a starter culture. Here, we demonstrate that administration of LFSP, but not SFSP, protects high-fat diet (HFD)-fed obese mice against non-alcohol fatty liver disease (NAFLD) and insulin resistance. LFSP suppressed body weight gain in parallel with reduction in fat accumulation in mesenteric adipose tissue (MAT) and the liver via modulation of MAT lipolysis and hepatic lipid uptake. LFSP-treated mice also had improved glucose tolerance and increased adiponectin levels concomitantly with enhanced AMPK activation in skeletal muscle and suppressed expression of pro-inflammatory cytokines in skeletal muscle and the liver. LFSP also attenuated HFD-induced gut permeability and lowered serum lipopolysaccharide level, providing an evidence for its probiotic effects, which was supported by the observation that treatment of a probiotic mixture of LFSP-originated Bacillus strains protected mice against HFD-induced adiposity and glucose intolerance. Our findings suggest that the intake of LFSP, but not SFSP, offers protection against NAFLD and insulin resistance, which is an effect of long-term fermentation resulting in elevated contents of active ingredients (especially flavonoids) and higher diversity and richness of Bacillus probiotic strains compared to SFSP.

Abstract
Mitochondria play a pivotal role in the fatty acid oxidation and have been found to be affected early during the macrovesicular fat accumulation in the hepatocytes. The fatty infiltration is the primary cause of oxidative stress and inflammation in the non-alcoholic fatty liver disease (NAFLD), which can lead to the peroxidation of phospholipids, such as cardiolipin. Oxidative stress-induced damage to mitochondrial DNA can result in the impairment of oxidative phosphorylation and further increases the generation of reactive oxygen species. The mitochondrial damage may eventually lead to apoptotic death of hepatocytes. The apoptosis along with the generated cytokines from the stellate and Kupffer cells further augment the fibrotic changes to advance the disease. Hence, alleviation of the mitochondrial impairment, particularly in the early stages of NAFLD, may prevent the progression of the disease. Among the various experimentally studied mitochondrial-targeted agents, triphenylphosphonium cation ligated ubiquinone Q10 and vitamin E, Szeto-Scheller peptides, and superoxide dismutase mimetic-salen manganese complexes (EUK-8 and EUK-134) have been found to be most promising. In addition to these mitochondrial-targeted agents, a novel area of therapy called mitotherapy have also emerged. However, clinical studies conducted so far are still fragmentary to validate their efficacy. This review article discusses the mitochondria-targeted molecules and their potential role in the treatment of NAFLD.

Abstract
AIMS Baicalin (BA), an active flavonoid compound originating from the herb of Scutellaria baicalensis Georgi, has been previously shown to exert anti-inflammation and anti-oxidant effects in liver diseases. However, the potential role of BA in the regulation of non-alcoholic steatohepatitis (NASH) remains elusive. In this study, we newly explored the hepatoprotective effects of BA in MCD diet-induced NASH by ameliorating hepatic steatosis, inflammation, fibrosis and apoptosis. MAIN METHODS NASH was induced in mice fed a methionine and choline-deficient (MCD) diet for 4weeks. The mice were simultaneously treated with or without BA for 4weeks. Serum liver functional markers and inflammatory indicators were assessed by biochemical and ELISA methods, respectively. The livers were histologically examined using H&E, Oil Red O and Masson's trichrome staining methods. The qRT-PCR, IHC and Western blotting assays were applied to analyze mechanisms underlying BA protection. KEY FINDINGS BA treatment significantly attenuated MCD diet-induced hepatic lipid accumulation partly through regulating the expression of SREBP-1c, FASN, PPARα and CPT1a. BA treatment dramatically suppressed MCD diet-induced hepatic inflammation, which was associated with decrease in serum TNF-α, IL-1β and MCP-1 production, macrophage influx and suppression of nuclear factor-κB activation. Additionally, BA was proved to prevent liver fibrosis, which appears to be mediated by inhibition of α-SMA, TGF-β1 and Col1A1. Furthermore, BA markedly inhibited hepatocyte apoptosis and cleaved caspase-3 protein expression in MCD diet-induced mice. SIGNIFICANCE These results provide a possible basis of the underlying mechanism for the application of BA in the treatment of NASH.

Abstract
Nonalcoholic fatty liver disease (NAFLD) affects 25-30% of the general population worldwide and this high prevalence is linked with lifestyle and dietetic changes, not only in Western countries, but also in the urban areas of developing countries. Several pharmacological approaches were proposed in the treatment of NAFLD, but the reported results are inconclusive. International guidelines recommended the reduction of dietary fat and fructose, in association with some physical activity. In this context, it was reported that the protective effects of traditional Mediterranean diet, related to the high concentration of antioxidant compounds, particularly of polyphenols. Polyphenols are a heterogeneous class of plant derived compounds, with some proven hepatoprotective effects. Our opinion is that the adherence to traditional Mediterranean diet characterized by the consumption of antioxidant-rich foods in general and of polyphenols in particular, can be considered as a potential new approach in the treatment of NAFLD.

Abstract
SCOPE (-)-Epicatechin (EC) is a natural flavanol monomer found in cocoa, green tea, and a variety of other plant foods. In this study, effects of EC on blood lipids and hepatic steatosis, and the underlying mechanisms were investigated. METHODS AND RESULTS A hyperlipidemic rat model was induced by high-fat, high-cholesterol diet. EC was then administrated to the animals by gavage at doses of 10, 20, 40 mg/kg body weight (BW) for 12 weeks. Simvastatin was included as a positive control. The results showed that EC significantly reduced total cholesterol, LDL cholesterol and triglyceride, alleviated liver fat accumulation, while increased HDL cholesterol, in hyperlipidemic rats. EC also reduced lipid peroxidation, inhibited the pro-inflammatory cytokines, and lowered serum AST and ALT. The potential molecular mechanisms of EC underlying these effects were proposed to be associated to regulating Insig-1-SREBP-SCAP pathway, and other lipid metabolic related genes including LXR-α, FAS, and SIRT1. CONCLUSION EC effectively improved blood lipid profile and protected liver from accumulating excessive fat in hyperlipidemic rats. The results shed a light on the potential role of EC as a promising natural product in preventing hyperlipidemia and nonalcoholic fatty liver disease.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a common clinicopathological condition, encompassing a range of conditions caused by lipid deposition within liver cells. To date, no approved drugs are available for the treatment of NAFLD, despite the fact that it represents a serious and growing clinical problem in the Western world. Identification of the molecular mechanisms leading to NAFLD-related fat accumulation, mitochondrial dysfunction and oxidative balance impairment facilitates the development of specific interventions aimed at preventing the progression of hepatic steatosis. In this review, we focus our attention on the role of dysfunctions in mitochondrial bioenergetics in the pathogenesis of fatty liver. Major data from the literature about the mitochondrial targeting of some antioxidant molecules as a potential treatment for hepatic steatosis are described and critically analysed. There is ample evidence of the positive effects of several classes of antioxidants, such as polyphenols (i.e., resveratrol, quercetin, coumestrol, anthocyanins, epigallocatechin gallate and curcumin), carotenoids (i.e., lycopene, astaxanthin and fucoxanthin) and glucosinolates (i.e., glucoraphanin, sulforaphane, sinigrin and allyl-isothiocyanate), on the reversion of fatty liver. Although the mechanism of action is not yet fully elucidated, in some cases an indirect interaction with mitochondrial metabolism is expected. We believe that such knowledge will eventually translate into the development of novel therapeutic approaches for fatty liver.

Abstract
This study investigated the effect of defatted pepper seed ethanolic extract (DPSE) on high-fat diet-induced obesity in C57BL/6J mice. The mice were fed a normal diet (ND), high fat diet (HFD), or HFD in combination with DPSE (100 and 200mg/kg body weight) for 7 weeks. Supplementing the HFD of mice with DPSE significantly decreased body weight gain and food efficiency ratio induced by HFD. The amount of epididymal fat and size of adipocytes were also dramatically reduced by DPSE supplementation. Although no statistical significance was found between the HFD and HFD plus DPSE groups in plasma fat deposition, liver weight, and hepatic cholesterol contents were significantly reduced in the DPSE-treated group. In conclusion, these results suggest that DPSE could prevent obesity and adiposity. These effects may be important in developing therapeutic agents against obesity in future.
