Resveratrol is a nutraceutical with several therapeutic effects. It has been shown to mimic effects of caloric restriction, exert anti-inflammatory and anti-oxidative effects, and affect the initiation and progression of many diseases through several mechanisms. While there is a wealth of in vitro and in vivo evidence that resveratrol could be a promising therapeutic agent, clinical trials must confirm its potential. In this work, we reviewed the current clinical data available regarding the pharmacological action of resveratrol...

BACKGROUND: Studies have demonstrated that resveratrol (a natural polyphenol) and caloric restriction activate Sirtuin-1 (SIRT1) and induce autophagy. Furthermore, autophagy is induced by the SIRT1-FoxO signaling pathway and was recently shown to be a critical protective mechanism against non-alcoholic fatty liver disease (NAFLD) development. We aimed to compare the effects of resveratrol and caloric restriction on hepatic lipid metabolism and elucidate the mechanism by which resveratrol supplementation and caloric restriction alleviate hepatosteatosis by examining the molecular interplay between SIRT1 and autophagy...

Resveratrol (RES) has the ability to ameliorate non-alcoholic fatty liver disease (NAFLD) and the mechanism remains unclear. Hence, using high-fat diet (HFD) obese rat model, we investigated the effect of low dose of RES (20 mg/kg) on hepatic Sterol regulatory element-binding proteins (SREBPs)-lipogenesis pathway, enzymes involved in β-oxidation and activity of pancreatic lipase. 4 groups of rats (n=8) of either control (12 % of calories as fat) or HFD (40 % of calories as fat), both were administered with either normal saline as vehicle or RES as a concomitant treatment for 8 weeks on a daily basis, orally...

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...

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD), the most common chronic liver disease, is the leading cause of cryptogenic cirrhosis and has consistently been implicated in related metabolic disorders, such as dyslipidemia and type 2 diabetes (T2D). However, the pathogenesis of NAFLD remains to be elucidated, and no established therapeutic regimens for treating NAFLD exist. Adenosine monophosphate (AMP)-activated protein kinase (AMPK), the main cellular energy sensor, has been implicated as a key regulator of hepatic lipid and glucose metabolism...

Non-alcoholic fatty liver disease (NAFLD) is one of the leading causes of chronic liver diseases around the world due to the modern sedentary and food-abundant lifestyle, which is characterized by excessive fat accumulation in the liver related with causes other than alcohol abuse. It is widely acknowledged that insulin resistance, dysfunctional lipid metabolism, endoplasmic reticulum stress, oxidative stress, inflammation, and apoptosis/necrosis may all contribute to NAFLD. Autophagy is a protective self-digestion of intracellular organelles, including lipid droplets (lipophagy), in response to stress to maintain homeostasis...

As a sugar additive, fructose is widely used in processed foods and beverages. Excessive fructose consumption can cause hepatic steatosis and dyslipidemia, leading to the development of metabolic syndrome. Recent research revealed that fructose-induced nonalcoholic fatty liver disease (NAFLD) is related to several pathological processes, including: (1) augmenting lipogenesis; (2) leading to mitochondrial dysfunction; (3) stimulating the activation of inflammatory pathways; and (4) causing insulin resistance...

Nonalcoholic fatty liver disease (NAFLD) is considered to be one of the most common liver pathologies that occur widely among societies with a predominance of the Western dietary pattern. NAFLD may progress from hepatic steatosis to nonalcoholic steatohepatitis (NASH), subsequently leading to cirrhosis and becoming a major cause of hepatocellular carcinoma. Thus its prevention and therapy play an important role in hepatology. To our knowledge, there is no effective treatment for patients with NAFLD. The aim of this review was to summarize the results of recent alternative treatment studies conducted both on cell cultures and in vivo that concern molecular effects of resveratrol (3,5,4'-trihydroxystilbene) in the treatment of NAFLD...

OBJECTIVES: Non-alcoholic fatty liver disease (NAFLD) is associated with impaired liver function, and resveratrol could suppress NAFLD progression. This study examined the effects of NAFLD on the expression of major cytochrome P450 (CYP) subtypes in the liver and whether the expression could be attenuated by resveratrol. METHODS: C57BL/6 mice (male, 10 weeks of age) were fed a high-fat and high-sucrose (HFHS) diet to induce NAFLD. Major Cyp subtype mRNA expression in the liver was measured by real-time RT-PCR...

Nonalcoholic fatty liver disease (NAFLD) is characterized by high levels of nonesterified fatty acids (NEFA), inflammation, and hepatic steatosis. Inflammation plays a crucial role in the development of fatty liver. Resveratrol (RSV) supplement could improve inflammatory response and hepatic steatosis, whereas the underlying mechanism was not well understood. In this study, mice fed with high-fat diet (HFD) exhibited severe hepatic injury and high blood concentrations of the inflammatory cytokines TNF-α, IL-6, and IL-1β...

Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease with rising prevalence. Increasing evidence has demonstrated that resveratrol, a dietary phytochemical, is capable of attenuating NAFLD development and progression; however, results from clinical studies are inconsistent and inconclusive. Here, we conducted a meta-analysis to evaluate the efficacy of resveratrol on NAFLD, using several parameters to provide new insights for clinical application. We systematically searched EMBASE, PubMed, Science Citation Index, Elsevier, and Cochrane Library databases for studies published up to date (July 2016), in English, to identify and screen eligible, relevant studies...

Non-alcoholic fatty liver disease (NAFLD) is an accumulation of fat in the liver despite a low level of alcohol intake, with signs of hepatomegaly. Although in the past, NAFLD was predominantly viewed as an aspect of metabolic syndrome, it is now considered that it should be classified as an independent condition similar to obesity, diabetes, and hypertension. Therefore, new treatment strategies, not based on correcting insulin resistance, are needed for NAFLD. This work analyzes methods of prevention, therapeutic approaches, and mechanisms involved in NAFLD, focusing on the use of flavonoids (epigallocatechin-3-gallate, resveratrol, anthocyanins, and isoflavones) with high antioxidant capacity...

The inflammatory mediator high-mobility group box 1 (HMGB1) plays a critical role in the pathogenesis of non-alcoholic fatty liver disease (NAFLD). However, the regulation of HMGB1 in NAFLD, particularly through sirtuin 1 (SIRT1), remains unclear. In this study, we investigated the role of SIRT1-mediated inhibition of HMGB1 release in NAFLD and the effect of salvianolic acid B (SalB), which is a water-soluble phenolic acid extracted from Radix Salvia miltiorrhiza, on NAFLD through SIRT1/HMGB1 signaling. In vivo, SalB treatment significantly attenuated high-fat diet (HFD)-induced liver damage, hepatic steatosis, and inflammation...

Non-alcoholic steatohepatitis (NASH), the progressive form of non-alcoholic fatty liver disease (NAFLD), is emerging as a main health problem in industrialized countries. Lifestyle modifications are effective in the treatment of NAFLD; however, the long-term compliance is low. Therefore, several pharmacological treatments have been proposed but none has shown significant efficacy or long-term safety. Natural polyphenols are a heterogeneous class of polyphenolic compounds contained in vegetables, which are being proposed for the treatment of different metabolic disorders...

BACKGROUND AND AIM: Non-alcoholic steatohepatitis (NASH) is a leading cause of chronic liver disease with few therapeutic options. Resveratrol (RSV) prevents the development of steatosis in a number of experimental fatty liver (non-alcoholic fatty liver [NAFL]) models, but the preventive or therapeutic effects on experimental NASH are not yet clarified, and clinical results on non-alcoholic fatty liver disease are ambiguous. Thus, we aimed to compare the RSV-mediated preventive and therapeutic effects on experimental NAFL and NASH...
