Abstract
As the important barrier of intraocular tissue, cornea is easy to suffer various kinds of injuries. Among them, acute alkali burn is a thorny ophthalmic emergency event, which can lead to corneal persistent epithelial defects, ulcers, and even perforation. Ferroptosis, a mode of regulatory cell death, has been found to play a key role in the process of corneal alkali burn, of which lipid peroxidation and intracellular iron levels are considered to be the possible therapeutic targets. To seek new effective treatments, the study herein focused on the occurrence of oxidative stress and ferroptosis in corneal alkali burn, exploring the role of phytic acid (PA), a natural small molecule with both antioxidant and iron chelating capacity, in the repair of corneal epithelial injury. The in vivo therapeutic results showed that PA eyedrops treatment promoted the recovery of corneal morphology and function, and in vitro experiments proved that PA prompted the repair of oxidative stress induced-corneal epithelial injury through ferroptosis inhibition. In addition, better drug treatment effect could be achieved through hydrogel delivery and sustained release, and our in vivo experiments showed the superior therapeutic effects of PA delivered by PVA hydrogels with larger molecular weights on corneal injury. In summary, this study demonstrated the excellent effect of natural small molecule PA with antioxidant and high efficiency chelating ferrous ions on ferroptosis inhibition, and showed the outstanding application prospect of PVA/PA hydrogels in the treatment of corneal epithelial injury.

Abstract
We highlight the latest work of Qiu et al. on the core mechanism of ferroptosis induced by rare phospholipids with two polyunsaturated fatty acyl tails (PL-PUFA2s), which has been published in Cell. It has long been acknowledged that PLs containing one PUFA tail (PL-PUFA1s) serve as substrates for phospholipid peroxidation during the process of ferroptosis, owing to their susceptibility to oxidation and prevalence in vivo. However, the authors note that PL-PUFA2s, rather than PL-PUFA1s, represent critical lipid classes involved in the pro-ferroptosis process. Exogenous phosphatidylcholine-PUFA2s accumulate in mitochondria and combine with Complex I within the electron transport chain, thereby potentially resulting in an elevation of mitochondrial reactive oxygen species levels. Then, these mitochondrial peroxides prompt the substantial accumulation of peroxides within the endoplasmic reticulum, ultimately culminating in ferroptosis. These findings shed light on the potential molecular mechanisms underlying the induction of ferroptosis by dietary PL-PUFA2s and offer novel insights for both the evaluation of cellular iron death sensitivity and the treatment of cancer. This article will provide a more comprehensive elucidation of the paper and facilitate an enhanced understanding of the underlying mechanisms for readers.

Antioxidants (Basel) 2024; 13:731. [PMID: 38929170 PMCID: PMC11201095 DOI: 10.3390/antiox13060731] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2024] [Revised: 06/11/2024] [Accepted: 06/13/2024] [Indexed: 06/28/2024] Open
Abstract
Oxidative stress plays a central role in most chronic liver diseases and, in particular, in metabolic dysfunction-associated fatty liver disease (MAFLD), the new definition of an old condition known as non-alcoholic fatty liver disease (NAFLD). The mechanisms leading to hepatocellular fat accumulation in genetically predisposed individuals who adopt a sedentary lifestyle and consume an obesogenic diet progress through mitochondrial and endoplasmic reticulum dysfunction, which amplifies reactive oxygen species (ROS) production, lipid peroxidation, malondialdehyde (MDA) formation, and influence the release of chronic inflammation and liver damage biomarkers, such as pro-inflammatory cytokines. This close pathogenetic link has been a key stimulus in the search for therapeutic approaches targeting oxidative stress to treat steatosis, and a number of clinical trials have been conducted to date on subjects with NAFLD using drugs as well as supplements or nutraceutical products. Vitamin E, Vitamin D, and Silybin are the most studied substances, but several non-pharmacological approaches have also been explored, especially lifestyle and diet modifications. Among the dietary approaches, the Mediterranean Diet (MD) seems to be the most reliable for affecting liver steatosis, probably with the added value of the presence of extra virgin olive oil (EVOO), a healthy food with a high content of monounsaturated fatty acids, especially oleic acid, and variable concentrations of phenols (oleocanthal) and phenolic alcohols, such as hydroxytyrosol (HT) and tyrosol (Tyr). In this review, we focus on non-pharmacological interventions in MAFLD treatment that target oxidative stress and, in particular, on the role of EVOO as one of the main antioxidant components of the MD.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a potentially serious disease that affects 30 % of the global population and poses a significant risk to human health. However, to date, no safe, effective and appropriate treatment modalities are available. In recent years, ferroptosis has emerged as a significant mode of cell death and has been found to play a key regulatory role in the development of NAFLD. In this study, we found that arbutin (ARB), a natural antioxidant derived from Arctostaphylos uva-ursi (L.), inhibits the onset of ferroptosis and ameliorates high-fat diet-induced NAFLD in vivo and in vitro. Using reverse docking, we identified the demethylase fat mass and obesity-related protein (FTO) as a potential target of ARB. Subsequent mechanistic studies revealed that ARB plays a role in controlling methylation of the SLC7A11 gene through inhibition of FTO. In addition, we demonstrated that SLC7A11 could alleviate the development of NAFLD in vivo and in vitro. Our findings identify the FTO/SLC7A11 axis as a potential therapeutic target for the treatment of NAFLD. Specifically, we show that ARB alleviates NAFLD by acting on the FTO/SLC7A11 pathway to inhibit ferroptosis.

Abstract
Metabolic-associated fatty liver disease (MAFLD), formerly referred to as non-alcoholic fatty liver disease (NAFLD), is a common liver disease characterized by an abnormal buildup of fat in liver. This study aimed to investigate whether bioactive dipeptides mitigate high-fat and high-fructose corn syrup diet (HFFD)-induced MAFLD in C57BL/6J mice. Sixty male C57BL/6J mice were randomly divided into six groups. The naïve group (untreated) was fed a standard chow diet and other groups were fed with HFFD along with vehicle and bioactive dipeptides treatment throughout experiment period. The control group received vehicle, YF10 and YF50 groups received Tyr-Phe, 10 and 50 mg/kg/day, FY10 and FY50 groups received Phe-Tyr, 10 and 50 mg/kg/day. At the end of experiment, body weight was recorded, and glucose homeostasis was assessed. Mice were sacrificed and blood samples were collected to measure biochemical parameters. Further, liver, visceral fat pads, and other organs were acutely dissected, weighed, and processed. Histopathological and immunohistochemical changes were analyzed. Long-term HFFD feeding resulted in elevated body weight gain, liver weight, visceral adiposity, liver injury, fasting hyperglycemia, hyperinsulinemia, and hyperlipidemia. It also increased severe hepatic steatosis, chronic low-grade inflammation, oxidative stress, mitochondrial dysfunction, and lipid peroxidation. However, bioactive dipeptides dose-dependently alleviated these complications which are associated with MAFLD by modulating adipokines secretion and antioxidant defense system via upregulation of Nrf2/HO-1 expressions. This study highlights potential of bioactive dipeptides as a promising approach for prevention and/or treatment of MAFLD induced by HFFD, providing novel insights into alternative therapeutic strategies.

Melatonin alleviates cadmium-induced nonalcoholic fatty liver disease in ducks by alleviating autophagic flow arrest via PPAR-α and reducing oxidative stress. Poult Sci 2023; 102:102835.

Abstract
Cadmium (Cd) is an important environmental pollutant that causes liver damage and induces nonalcoholic fatty liver disease (NAFLD). NAFLD is a fat accumulation disease and has significant effects on the body. Melatonin (Mel) is an endogenous protective molecule with antioxidant, anti-inflammatory, antiobesity, and antiaging effects. However, whether Mel can alleviate Cd-induced NAFLD and its mechanism remains unclear. First, in vivo, we found that Mel maintained mitochondrial structure and function, inhibited oxidative stress, and reduced Cd-induced liver injury. In addition, Mel alleviated lipid accumulation in the liver induced by Cd. In this process, Mel inhibits fatty acid production and promotes fatty acid oxidation. Interestingly, Mel regulated PPAR-α expression and alleviated Cd-induced autophagy blockade. In vitro model, the oil Red O staining, and WB results showed that Mel alleviated Cd-induced lipid accumulation. In addition, RAPA was used to activate autophagy to alleviate Cd-induced lipid accumulation, and TG was used to block autophagy flux to aggravate Cd-induced autophagy accumulation. After knocking down PPAR-α, the autophagosome fusion with lysosomes, and autophagic flux was inhibited and increased Cd-induced lipid accumulation. Mel alleviates mitochondrial damage and oxidative stress, and attenuates Cd-induced NAFLD by restoring the expression of PPAR-α and restoring autophagy flux.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a common chronic hepatic disorder characterized by hepatic lipid accumulation. This study explored the effect of betulin (BE), a terpenoid with promising antioxidant, anti-inflammatory and insulin sensitizing effects, on NAFLD induced by high fat diet (HFD). Rats received HFD and BE (15 and 30 mg/kg) for 12 weeks and blood and liver samples were collected for analyses. HFD caused hyperlipidemia, cholesterol and triglycerides accumulation in the liver, hepatocellular ballooning, fibrosis, insulin resistance (IR), lipid peroxidation (LPO), and NF-kB p65 upregulation. BE ameliorated serum and liver lipids, blood glucose, and insulin, liver LPO, prevented steatosis and fibrosis, suppressed NF-kB p65 and enhanced antioxidants in HFD-fed rats. BE downregulated ACC1 and FAS, and upregulated Nrf2, HO-1 and SIRT1 in the liver of HFD-fed rats. In silico investigations revealed the binding affinity of BE towards NF-kB, Keap1, HO-1 and SIRT1. In conclusion, BE attenuated HFD-induced NAFLD by ameliorating hyperlipidemia, IR, lipogenesis, liver lipid accumulation, and oxidative stress. The protective effect of BE was associated with enhanced Nrf2/HO-1 signaling and SIRT1.

Abstract
The indiscriminate use of oral ferrous sulfate (FeSO4) doses induces significant oxidative damage to health. However, carotene-rich foods such as buriti oil can help the endogenous antioxidant defense and still maintain other body functions. This study aimed to assess the effects of buriti oil intake in iron-overloaded rats by FeSO4 administration. Buriti oil has β-carotene (787.05 mg/kg), α-tocopherol (689.02 mg/kg), and a predominance of monounsaturated fatty acids (91.30 g/100 g). Wistar rats (n = 32) were subdivided into two control groups that were fed a diet containing either soybean or buriti oil; and two groups which received a high daily oral dose of FeSO4 (60 mg/kg body weight) and fed a diet containing either soybean (SFe) or buriti oil (Bfe). The somatic and hematological parameters, serum lipids, superoxide dismutase (SOD), and glutathione peroxidase (GPx) were determined after 17 days of iron overload. Somatic parameters were similar among groups. BFe showed a decrease in low-density lipoprotein (38.43%) and hemoglobin (7.51%); an increase in monocytes (50.98%), SOD activity in serum (87.16%), and liver (645.50%) hepatic GPx (1017.82%); and maintained serum GPx compared to SFe. Buriti oil showed systemic and hepatic antioxidant protection in iron-overloaded rats, which may be related to its high carotenoid, tocopherol, and fatty acid profile.

Abstract
The increasing abundance of fine particulate matter (PM2.5) in the environment has increased susceptibility to acute exacerbation of COPD (AECOPD). During PM2.5 exposure, excessive reactive oxygen species (ROS) production triggers a redox imbalance, which contributes to damage to organelles and disruption of homeostasis. At present, there are limited data on whether NOX4/Nrf2 redox imbalance increases susceptibility to acute exacerbation of COPD (AECOPD), and the underlying mechanism is unclear. Therefore, the current study was aimed to evaluate the role of NOX4/Nrf2 redox balance on AECOPD induced by PM2.5-CS-exposure. Here, we report that PM2.5 exacerbates cytotoxicity by enhancing NOX4/Nrf2 redox imbalance-mediated mitophagy. First, exposure to a low-dose of PM2.5 (200 μg/ml) significantly exacerbated oxidative stress and mitochondrial damage by increasing the ROS overproduction, enhancing the excessive NOX4/Nrf2 redox imbalance, decreasing the mitochondrial membrane potential (MMP), and enhancing the mitochondrial fragmentation that were caused by a low-dose of CSE (2.5%). Second, coexposure to PM2.5 and CSE (PM2.5-CSE) induced excessive mitophagy. Third, PM2.5 exacerbated CS-induced COPD, as shown by excessive inflammatory cell infiltration, inflammatory cytokine production and mucus hypersecretion, goblet cell hyperplasia, NOX4/Nrf2 redox imbalance, and mitophagy, these effects triggered excessive ROS production and mitochondrial damage in mice. Mechanistically, PM2.5-CS-induced excessive levels of mitophagy by triggering redox imbalance, leading to greater cytotoxicity and AECOPD; however, reestablishing the NOX4/Nrf2 redox balance via NOX4 blockade or mitochondria-specific ROS inhibitor treatment alleviated this cytotoxicity and ameliorated AECOPD. PM2.5 may exacerbate NOX4/Nrf2 redox imbalance and subsequently enhance mitophagy by increasing the ROS and mito-ROS levels, thereby increasing susceptibility to AECOPD.

Abstract
Ferroptosis is an iron‐dependent form of non‐apoptotic cell death implicated in liver, brain, kidney, and heart pathology. How ferroptosis is regulated remains poorly understood. Here, we show that PPARα suppresses ferroptosis by promoting the expression of glutathione peroxidase 4 (Gpx4) and by inhibiting the expression of the plasma iron carrier TRF. PPARα directly induces Gpx4 expression by binding to a PPRE element within intron 3. PPARα knockout mice develop more severe iron accumulation and ferroptosis in the liver when fed a high‐iron diet than wild‐type mice. Ferrous iron (Fe2+) triggers ferroptosis via Fenton reactions and ROS accumulation. We further find that a rhodamine‐based "turn‐on" fluorescent probe(probe1) is suitable for the in vivo detection of Fe2+. Probe1 displays high selectivity towards Fe2+, and exhibits a stable response for Fe2+ with a concentration of 20 μM in tissue. Our data thus show that PPARα activation alleviates iron overload‐induced ferroptosis in mouse livers through Gpx4 and TRF, suggesting that PPARα may be a promising therapeutic target for drug discovery in ferroptosis‐related tissue injuries. Moreover, we identified a fluorescent probe that specifically labels ferrous ions and can be used to monitor Fe2+in vivo.

High Iron Exposure from the Fetal Stage to Adulthood in Mice Alters Lipid Metabolism. Nutrients 2022; 14:nu14122451.

Abstract
Iron supplementation is recommended during pregnancy and fetal growth. However, excess iron exposure may increase the risk of abnormal fetal development. We investigated the potential side effects of high iron levels in fetuses and through their adult life. C57BL/6J pregnant mice from 2 weeks of gestation and their offspring until 30 weeks were fed a control (CTRL, FeSO4 0 g/1 kg) or high iron (HFe, FeSO4 9.9 g/1 kg) diets. HFe group showed higher iron accumulation in the liver with increased hepcidin, reduced TfR1/2 mRNAs, and lowered ferritin heavy chain (FTH) proteins in both liver and adipose tissues despite iron loading. HFe decreased body weight, fat weight, adipocyte size, and triglyceride levels in the blood and fat, along with downregulation of lipogenesis genes, including PPARγ, C/EBPα, SREBP1c, FASN, and SCD1, and fatty acid uptake and oxidation genes, such as CD36 and PPARα. UCP2, adiponectin, and mRNA levels of antioxidant genes such as GPX4, HO-1, and NQO1 were increased in the HFe group, while total glutathione was reduced. We conclude that prolonged exposure to high iron from the fetal stage to adulthood may decrease fat accumulation by altering ferritin expression, adipocyte differentiation, and triglyceride metabolism, resulting in an alteration in normal growth.

Abstract
Oxidative stress is an imbalance between oxidants and antioxidants in favor of the oxidants, leading to a disruption of redox signaling and control, and/or molecular damage altering cellular functions. This redox imbalance may trigger different responses depending on the antioxidant potential of a given cell, the level of reactive oxygen/nitrogen species (ROS/RNS) attained and the time of exposure, with protective effects being induced at low ROS/RNS levels in acute or short-term conditions, and harmful effects after high ROS/RNS exposure in prolonged situations. Relevant conditions underlying liver redox imbalance include iron overload associated with ROS production via Fenton chemistry and the magnitude of the iron labile pool achieved, with low iron exposure inducing protective effects related to nuclear factor-κB, signal transducer and activation of transcription 3, and nuclear factor erythroid-related factor 2 (Nrf2) activation and upregulation of ferritin, hepcidin, acute-phase response and antioxidant components, whereas high iron exposure causes drastic oxidation of biomolecules, mitochondrial dysfunction, and cell death due to necrosis, apoptosis and/or ferroptosis. Redox imbalance in nonalcoholic fatty liver disease (NAFLD) is related to polyunsaturated fatty acid depletion, lipogenic factor sterol regulatory element-binding protein-1c upregulation, fatty acid oxidation-dependent peroxisome proliferator-activated receptor-α downregulation, low antioxidant factor Nrf2 and insulin resistance, a phenomenon that is exacerbated in nonalcoholic steatohepatitis triggering an inflammatory response. Thyroid hormone (T3 ) administration determines liver preconditioning against ischemia-reperfusion injury due to the redox activation of several transcription factors, AMP-activated protein kinase, unfolded protein response and autophagy. High grade liver redox imbalance occurring in severe iron overload is adequately handled by iron chelation, however, that underlying NAFLD/NASH is currently under study in several Phase II and Phase III trials.

Abstract
AbstractLiver and kidney diseases are becoming order of the day in both developed and developing countries as a result of environmental pollutants such as lead. Restorative activities of methanol and methanol/acetone phenolic-rich extracts (MPR and MAPR, respectively) of the N. latifolia fruit (NLF) on lead acetate-induced liver and kidney damaged were assessed in Wistar rats. The antioxidant activities of both phenolic-rich extracts of NLF were also carried out using standard methods. Seven groups of Wistar rats comprising of 5 rats each were used for the study and 1000 mg/kg body weight (bw.) of lead acetate solution was administered orally to the 6 groups of animals to induce liver and kidney damage. The high and low dosages of 300 and of 150 mg/kg body weight (bw.) of both MPR and MAPR were administered orally to four groups for 14 days along positive (100 mg/kg bw. of silymarin), negative (treated with the placebo) and naïve control (non-induced). The percentage DPPH radical scavenging activities, ferric reducing antioxidant power and percentage inhibition of lipid peroxidation show high antioxidants activities dose-dependently. Furthermore, administration of lead acetate significantly (p > 0.05) reduces the weight gain and elevates the liver and kidney relative weight as well as their respective damage biomarkers with distortions in their histologies. However, treatment with MPR and MAPR resulted in significant (p < 0.05) improve in the percentage body weight gain, relative liver and kidney weight as well as restoration of the activities of the liver and kidney functions biomarkers of the treated animals. Likewise, lesser hepatic and renal cells injury were also observed in the treated groups with MAPR being more active at high dosage which significantly (p < 0.05) compared well with normal group. Hence, the phenolics content of the N. latifolia fruit can be exploited further for drug development for the management kidney and liver damage arise from lead-induced toxicity.

Abstract
A diet high in saturated fat leads to skeletal muscle deteriorations including insulin resistance, mitochondrial dysfunction and muscle fiber atrophy. Consumption of long-chain polyunsaturated fatty acids and exercise have shown promise in ameliorating high-fat diet (HFD)-induced oxidative stress and inflammation. However, the impact of extra virgin olive oil (EVOO) on mitochondrial homeostasis in muscle is largely unknown. This study aimed to investigate whether 12 weeks of EVOO feeding alone and in conjunction with endurance training could protect against metabolic and mitochondrial dysfunction rat muscle with HFD. Female Sprague-Dawley rats were divided into 4 groups fed a control diet (C), HFD, EVOO diet, and EVOO diet with training (EVOO+T). Mitochondrial enzyme activity and protein content decreased with HFD compared to C, but were restored with EVOO and EVOO+T. EVOO+T elevated muscle cytochrome c and PGC-1α levels. HFD increased muscle proteolytic markers and protein ubiquitination, whereas these effects were not seen in EVOO and EVOO+T. HFD suppressed mitochondrial fusion protein level while increasing fission protein levels, but were restored with EVOO and EVOO+T. Mitophagy marker PINK1 content decreased with HFD, but was unchanged in EVOO and EVOO+T. EVOO+T upregulated autophagy markers, along with decreased phosphorylated/dephosphorylated FoxO3 ratio. Antioxidants enzyme levels were upregulated by EVOO and EVOO+T, and EVOO+T reduced HFD-induced lipid peroxidation. In conclusion, HFD impaired muscle oxidative capacity, promoted protein ubiquitination and mitochondrial fission, and upregulated autophagy markers. Replacement of HFD with EVOO corrected the observed adverse effects, while exercise training in conjunction with EVOO provided additional protection to the muscle.

Abstract
Alcoholic liver disease (ALD) is a worldwide health problem with limited therapeutic options, which is associated with gut-derived endotoxins, particularly lipopolysaccharide (LPS) and intestinal microbiota dysbiosis. Recently, probiotics, synbiotics and other food additive interventions have been shown to be effective in decreasing or preventing the progression of ALD. Bacillus subtilis (B. subtilis) and its metabolic products are widely used as food additives to maintain intestinal health, but the protective effects of B. subtilis against alcohol-induced liver injury are poorly understood. In the present study a chronic alcohol-induced liver injury model was constructed based on the Lieber-DeCarli diet and it aimed to determine whether dietary B. subtilis supplementation may alleviate alcohol-induced liver injury. Results revealed that prophylactic B. subtilis supplementation partially restored gut microbiota homeostasis and relieved alcohol-induced intestinal barrier injury, which significantly decreased the translocation of bacterial endotoxins to the blood. In addition, the decreased serum LPS alleviated hepatic inflammation via the toll-like receptor 4 pathway, resulting in improved hepatic structure and function. These results demonstrated that dietary B. subtilis supplementation imparts novel hepatoprotective functions by improving intestinal permeability and homeostasis.

Abstract
Plant polyphenols have promoting health features, including anti-mutagenic, anti-inflammatory, anti-thrombotic, anti-atherogenic, and anti-allergic effects. These polyphenols improve the immune system by affecting the white blood cell proliferation, as well as by the synthesis of cytokines and other factors, which contribute to immunological resistance. Olive trees are one of the most famous trees in the world. Whereas, olive olive oil and derivatives represent a large group of feeding resource for farm animals. In recent years, remarkable studies have been carried out to show the possible use of olive oil and derivatives for improvement of both animal performance and product quality. In vivo application of olive oil and its derived products has shown to maintain oxidative balance owing to its polyphenolic content. Consumption of extra virgin olive oil reduces the inflammation, limits the risk of liver damage, and prevents the progression of steatohepatitis through its potent antioxidant activities. Also, the monounsaturated fatty acids content of olive oil (particularly oleic acid), might have positive impacts on lipid peroxidation and hepatic protection. Therefore, this review article aims to highlight the nutritional applications and beneficial health aspects of olive oil and its effect on poultry production.

Abstract
Ethanol exposure frequently induces intestinal and liver injury, dysbiosis of the gut microbiota and vitamin C (VC) deficiency. Gut microbiota-targeted therapy is emerging as an important adjuvant method for protecting the body against ethanol-induced injury, particularly probiotics containing Lactobacillus acidophilus (LA). However, the feasibility and efficiency of using synbiotics containing LA and VC against ethanol-induced injury remained largely undetermined. To examine the advantages of LA+VC, their effect was evaluated in an ethanol-fed mouse model. The results suggested that LA+VC restored gut microbiota homeostasis and reinstated the immune balance of colonic T-regulatory cells (CD4+CD45+forkhead box p3+). In addition, intestinal barrier disorders were improved via upregulating tight junction proteins (claudin-2, zona occludens-1 and occludin) and mucus secretion, which prevented the translocation of lipopolysaccharide into circulatory systems and subsequently reduced the expression of Toll-like receptor 4 in liver tissues. In this context, LA+VC treatment reduced the inflammatory response in the liver, which was likely responsible for the improved liver function in ethanol-challenged mice. Collectively, these results indicated that LA+VC treatment significantly protected the intestine and liver from ethanol damage by enhancing intestinal barrier function and reducing systemic inflammation. The present study paved the way for further exploration of synbiotics based on Lactobacillus species and VC.

Abstract
Liver fibrosis is a histological change that often occurs due to hepatic stellate cell (HSC) activation and excessive formation of an extracellular matrix in the liver. Pelargonidin (PEL) is a natural anthocyanidin existing in blueberries, berries, strawberries, and red radishes and has been demonstrated to possess health beneficial effects. Herein, we investigated the effect of PEL on liver fibrosis induced by CCl4 and hepatic stellate cells induced by transforming growth factor-β (TGF-β). We found that PEL administration prevented liver injury and liver fibrosis induced by CCl4 in a dose-dependent manner. Further data revealed that PEL increased liver nuclear factor E2-related factor 2 (Nrf2) and reduced liver oxidative stress and the expression levels of NLRP3, caspase-1 and IL-1β. In TGF-β-challenged HSCs (LX-2 cells), PEL effectively inhibited the LX-2 cell activation. In addition, the anti-fibrosis effects of PEL in LX-2 cells were abolished by Nrf2 knockdown. In summary, our study demonstrated that PEL ameliorated CCl4-induced liver fibrosis and HSC activation induced by TGF-β. The possible molecular mechanisms of PEL in liver fibrosis may be attributed to its suppression of ROS-NLRP3-IL-1β signaling by Nrf2 activation.

Abstract
Arsenic trioxide (ATO)-induced hepatotoxicity limits the therapeutic effect of acute myelogenous leukemia treatment. Magnesium isoglycyrrhizinate (MgIG) is a natural compound extracted from licorice and a hepatoprotective drug used in liver injury. It exhibits anti-oxidant, anti-inflammatory and anti-apoptotic properties. The aim of the present study was to identify the protective action and underlying mechanism of MgIG against ATO-induced hepatotoxicity. A total of 50 mice were randomly divided into five groups (n=10/group): Control; ATO; MgIG and high- and low-dose MgIG + ATO. Following continuous administration of ATO for 7 days, the relative weight of the liver, liver enzyme, histological data, antioxidant enzymes, pro-inflammatory cytokines, cell apoptosis and changes in Kelch-like ECH-associated protein 1/nuclear factor erythroid 2-related factor 2 (Keap1-Nrf2) signaling pathway were observed. MgIG decreased liver injury, decreased the liver weight and liver index, inhibited oxidative stress and decreased the activity of glutathione, superoxide dismutase and catalase, production of reactive oxygen species and levels of pro-inflammatory cytokines, including IL-1β, IL-6 and TNF-α. Western blotting showed a decrease in Bax and caspase-3. There was decreased cleaved caspase-3 expression and increased Bcl-2 expression. MgIG notably activated ATO-mediated expression of Keap1 and Nrf2 in liver tissue. MgIG administration was an effective treatment to protect the liver from ATO-induced toxicity. MgIG maintained the level of Nrf2 in the liver and protected the antioxidative defense system to attenuate oxidative stress and prevent ATO-induced liver injury.

Abstract
Abstract
Background
In the present investigation an attempt was made to evaluate the potential of agnucastoside C (ACC), isolated from the leaves of Moringa oleifera in ameliorating thyrotoxicosis, hepatic lipid peroxidation (LPO) and hyperglycemia in female mice.
Methods
L-thyroxine (L-T4) at 0.5 mg/kg/d was administered through intra-peritoneal route for 15 consecutive days to induce thyrotoxicosis and then the effects of three different doses (10, 20 and 30 mg/kg body weight) of the isolated ACC for 21 days were investigated on the changes in serum thyroid hormones, insulin, glucose, different lipids; hepatic lipid peroxidation, enzymatic antioxidants such as superoxide dismutase, catalase and glutathione peroxidase, advanced oxidation protein products, reduced glutathione and in lipid peroxides.
Results
Following the administration of L-T4, serum T3, T4, insulin, glucose levels and the tissue LPO were increased with a decrease in serum thyroid stimulating hormone and antioxidative enzymes. However, administration of the test compound to hyperthyroid animals significantly decreased the levels of thyroid hormones, glucose and lipid peroxidation and normalized the concentration of insulin and tissue antioxidants, suggesting its antithyroid, antihyperglycemic and antiperoxidative potential. The T4-induced adverse effects on liver histology were also abolished. These findings suggest the possible use of the test compound in ameliorating thyrotoxicosis.
Conclusion
ACC exhibited antithyroidic, antihypoglycemic, antioxidative and insulin normalizing activities.

Abstract
Bavachinin, a natural bioactive flavanone, is reported to have many pharmacological proprieties, especially anti-osteoporosis activity. Here we aim to determine the roles of cytochrome P450s (CYP), UDP-glucuronosyltransferases (UGT), and efflux transporters in metabolism and drug-drug interactions (DDI) of bavachinin. Phase I metabolism and glucuronidation were performed by human liver microsomes (HLM) and human intestine microsomes (HIM). Reaction phenotyping was used to identify the main CYPs and UGTs. Gene silencing methods were employed to investigate the roles of breast cancer resistance protein (BCRP) and multidrug resistance-associated proteins (MRPs) in HeLa1A1 cells. Inhibition mechanisms towards CYPs and UGTs were explored through kinetic modeling. Three phase I metabolites (M1-M3) and one glucuronide (G1) were detected after incubation of bavachinin with HLM and HIM. The intrinsic clearance (CLint) values of M1 and G1 by HLM were 89.4 and 270.2 μL min-1 mg-1, respectively, while those of M3 and G1 by HIM were 25.8 and 247.1 μL min-1 mg-1, respectively. CYP1A1, 1A2, 1B1, 2C8, 2C19, and UGT1A1, 1A8 participated more in bavachinin metabolism. The metabolism showed marked species difference. BCRP and MRP4 were identified as the main contributors. Bavachinin displayed potent inhibitory effects against several CYP and UGT isozymes (K i = 0.28-2.53 μM). Bavachinin was subjected to undergo metabolism and disposition by CYPs, UGTs, BCRP, MRP4, and was also a potent non-selective inhibitor against several CYPs and UGTs.

Abstract
Studies focusing on the interaction of dietary and acute emotional stress on oxidative stress in cortex frontal and in brain mitochondria are scarce. Dietary-induced insulin resistance, as observed in Western diets, has been associated with increased oxidative stress causing mitochondrial dysfunction. We hypothesized that acute emotional stress could be an aggravating factor by impacting redox status in cortex and brain mitochondria. Thus, the aim of the present study was to evaluate the combination of an insulin resistance inducing high-fat/high-fructose (HF/HFr) diet and acute emotional stress on brain oxidative stress in rats. We measured several oxidative stress parameters (carbonyls, FRAP, TBARS assays, GSH, GSSG, oxidized DNA, mRNA expression of redox proteins (Nrf2), and uric acid). The HF/HFr diet resulted in increased oxidative stress both in the brain mitochondria and in the frontal cortex and decreased expression of the Nrf2 gene. The emotional stress induced an oxidative response in plasma and in brain mitochondria of the control group. In the HF/HFr group it triggered an increase expression of the redox transcription factor Nrf2 and its downstream antioxidant genes. This suggests an improvement of the redox stress tolerance in response to an enhanced production of reactive oxygen species. Accordingly, a blunted oxidative effect on several markers was observed in plasma and brain of HF/HFr-stressed group. This was confirmed in a parallel study using lipopolysaccharide as a stress model. Beside the Nrf2 increase, the stress induced a stronger UA release in HF/HFr which could take a part in the redox stress.

Abstract
Alcoholic fatty liver disease (AFLD), a major public health problem, has drawn clinical and scientific attention. The study aims to investigate the effect of Ganmeijian [crude extract of malt root, phosphoesterase complex (Pho)] on AFLD, and explore the possible mechanisms. An AFLD rat model was made. 30 and 60 mg/kg Pho were administrated through intestinal fistula for 5 weeks. Compared with those in model group, AST, LDL-C and TC in 30 mg/kg Pho group and TC in 60 mg/kg Pho group decreased. The mRNA level of Fas, Gpat1 and Srebp-1c in Pho groups was significantly reduced. The level of GSH-Px was increased, mitochondrial activity was improved, and the level of MDA and ROS was reduced in Pho groups. Pho shows a beneficial effect on AFLD. The mechanisms are possibly related to Pho inhibiting the expression of fat synthesis genes, protecting the function and increasing the activity of mitochondria in hepatocytes, then reducing the accumulation of ROS and the level of oxidative stress in the liver.

Abstract
Abstract
Backgroound
Lepidium pinnatifidum is a multipurpose, beneficial plant and known well for its indigenous therapeutic standards. Current study is aimed to investigate antioxidant and anti-inflammatory potency of Lepidium pinnatifidum.
L. pinnatifidum dried powder was extracted with crude methanol (LPM) and then fractionated with various solvents to get respective fractions, termed as, n-hexane (LPH), chloroform (LPC), ethyl acetate (LPE), butanol (LPB) and the aqueous fraction (LPA). Fractions were evaluated for total flavonoid and phenolic content. Antioxidant profile was quantified via an array of antioxidant assays. Anti inflammatory activity was evaluated in vitro, and further assessed by in vivo study in Sprague Dawley rat.
Result
Total phenolics (TPC) range from 48.15 ± 1.03–241.23 ± 1.07 mg GAE/g while total flavonoids (TFC) quantified were 16.32 ± 1.14–136.32 ± 1.14 mg RE/g. The in vitro antioxidant assays exhibited remarkable radicals scavenging action in different assays. Substantial positive correlation was instituted between TPC, TFC and various antioxidant assays. Inhibition of the heat induced protein denaturation reflected anti inflammatory potency, further supported by in vivo carrageenan induced paw edema.
Conclusion
The obtained results lead to suggesting the therapeutic perspective of L. pinnatifidum in oxidative stress and inflammation associated ailments. The bio active ingredients behind its potential protectivity needs to be further confirmed.

Abstract
The barrier-improving functions of fermented blueberry pomace (FBP) and its potential mechanism were investigated in this study. Polyphenols and the approximate composition of FBP were evaluated according to the National Standard of the People's Republic of China and the UPLC-MS system. Male C57BL/6 mice were fed a control diet (CD) or a high-fat diet (HFD) with or without FBP supplementation. Oxidative stress, inflammation, histological morphology and the expression of functional proteins in the small intestine of mice were evaluated using the enzyme linked immunosorbent assay (ELISA), quantitative polymerase chain reaction (qPCR) and western blotting. The content of protein, fat, soluble dietary fiber, insoluble dietary fiber and carbohydrates (non-dietary fiber) was 114.5 ± 1.5 g kg-1, 5.0 ± 0.2 g kg-1, 48.0 ± 0.1 g kg-1, 360.3 ± 2.2 g kg-1 and 423 g kg-1 (by difference), respectively. Thirty-six polyphenols were identified in FBP. FBP improved the growth of mice and attenuated hepatic and intestinal oxidative stress. Intestinal inflammation was significantly reduced through the decrease of tumor necrosis factor-alpha (TNF-α) and myeloperoxidase (MPO) as well as an increase of interleukin-10 (IL-10). FBP supplementation significantly improved the intestinal morphology and barrier function, potentially by mediating the NF-κB-MLCK signaling pathway. The supplementation of FBP in HFD mice enhanced the intestinal barrier function. This suggested that polyphenol-rich by-products might provide a similar health effect in HFD individuals.

Abstract
Gegen Qilian Decoction (GGQLD) is a well-established classic Chinese medicine prescription in treating nonalcoholic steatohepatitis (NASH). However, the molecular mechanism of GGQLD action on NASH is still not clear. This study aimed to assess the anti-NASH effect of GGQLD, and to explore its molecular mechanisms in vivo and in vitro. In HFD-fed rats, GGQLD decreased significantly serum triglyceride (TG), cholesterol (CHO), total bile acid (TBA), low-density lipoprotein (LDL), free fatty acid (FFA) and lipopolysaccharide (LPS) levels, increased levels of differentially expressed proteins (DEPs) Ahcy, Gpx1, Mat1a, GNMT, and reduced the expression of ALDOB. In RAW264.7 macrophages, GGQLD reduced the expression levels of inflammatory factors TNF-α and IL-6 mRNA, and diminished NASH by increasing differentially expressed genes (DEGs) CBS, Mat1a, Hnf4α and Pparα to reduce oxidative stress or lipid metabolism. The results of DEGs verification also showed that GGQLD up-regulated expressions of Hnf4α, Pparα and Cbs genes. In HepG2 cells, GGQLD decreased IL-6 levels and intracellular TG content, and inhibited FFA-induced expression of toll-like receptor 4 (TLR4). In summary, GGQLD abates NASH associated liver injuries via anti-oxidative stress and anti-inflammatory response involved inhibition of TLR4 signal pathways. These findings provide new insights into the anti-NASH therapy by GGQLD.

Abstract
Abstract
Background
Jatropha tanjorensis is a commonly consumed green leafy plant that has found usage in folk medicine. Sodium benzoate (C6H5COONa) is a widely used preservative in food/drink industries with potential cytotoxicity. Protective effect of some leafy plants on xenobiotic-induced toxicity have been established. Hence, this study sought to investigate the protective effect of methanolic leaf extract of Jatropha tanjorensis on sodium benzoate mediated renal and hepatic dysfunction in rats.
Results
Sodium benzoate treatment caused significant (P < 0.05) alteration in kidney (serum urea, uric acid, and creatinine) and liver (aspartate and alanine transaminases, acid and alkaline phosphatases) damage markers, serum albumin, globulin and total protein levels as well as cellular architecture which were significantly reversed in groups treated with the leaf extracts. Phytochemical screening of the leaf extract revealed the presence of terpenoids, saponins, cardiac glycosides, flavonoids and tannins.
Conclusion
Sodium benzoate-induced alterations in the renal and hepatic indices were mitigated following treatment with J. tanjorensis leaf extracts which suggests protective effect of the extract against sodium benzoate intoxication.

Abstract
The olive-oil-centered Mediterranean diet has been associated with extended life expectancy and a reduction in the risk of age-related degenerative diseases. Extra virgin olive oil (EVOO) itself has been proposed to promote a "successful aging", being able to virtually modulate all the features of the aging process, because of its great monounsaturated fatty acids content and its minor bioactive compounds, the polyphenols above all. Polyphenols are mostly antioxidant and anti-inflammatory compounds, able to modulate abnormal cellular signaling induced by pro-inflammatory stimuli and oxidative stress, as that related to NF-E2-related factor 2 (Nrf-2) and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), which have been identified as important modulators of age-related disorders and aging itself. This review summarizes existing literature about the interaction between EVOO polyphenols and NF-κB and Nrf-2 signaling pathways. Reported studies show the ability of EVOO phenolics, mainly hydroxytyrosol and tyrosol, to activate Nrf-2 signaling, inducing a cellular defense response and to prevent NF-κB activation, thus suppressing the induction of a pro-inflammatory phenotype. Literature data, although not exhaustive, indicate as a whole that EVOO polyphenols may significantly help to modulate the aging process, so tightly connected to oxidative stress and chronic inflammation.

Nonalcoholic fatty liver disease (NAFLD) is present in approximately 25% of the population worldwide. It is characterized by the accumulation of triacylglycerol in the liver, which can progress to steatohepatitis with different degrees of fibrosis, stages that lack approved pharmacological therapies and represent an indication for liver transplantation with consistently increasing frequency. In view that hepatic steatosis is a reversible condition, effective strategies preventing disease progression were addressed using combinations of natural products in the preclinical high-fat diet (HFD) protocol (60% of fat for 12 weeks). Among them, eicosapentaenoic acid (C20:5n-3, EPA) and docosahexaenoic acid (C22:5n-3, DHA), DHA and extra virgin olive oil (EVOO), or EPA plus hydroxytyrosol (HT) attained 66% to 83% diminution in HFD-induced steatosis, with the concomitant inhibition of the proinflammatory state associated with steatosis. These supplementations trigger different molecular mechanisms that modify antioxidant, antisteatotic, and anti-inflammatory responses, and in the case of DHA and HT co-administration, prevent NAFLD. It is concluded that future studies in NAFLD patients using combined supplementations such as DHA plus HT are warranted to prevent liver steatosis, thus avoiding its progression into more unmanageable stages of the disease.

Abstract
The administration of iron induces liver oxidative stress and depletion of long-chain polyunsaturated fatty acids (LCPUFAs), n-6/n-3 LCPUFA ratio enhancement and fat accumulation, which may be prevented by antioxidant-rich extra virgin olive oil (AR-EVOO) supplementation. Male Wistar rats were subjected to a control diet (50 mg iron/kg diet) or iron-rich diet (IRD; 200 mg/kg diet) with alternate AR-EVOO for 21 days. Liver fatty acid (FA) analysis was performed by gas-liquid chromatography (GLC) after lipid extraction and fractionation, besides Δ-5 desaturase (Δ-5 D) and Δ6-D mRNA expression (qPCR) and activity (GLC) measurements. The IRD significantly (p < 0.05) increased hepatic total fat, triacylglycerols, free FA contents and serum transaminases levels, with diminution in those of n-6 and n-3 LCPUFAs, higher n-6/n-3 ratios, lower unsaturation index and Δ5-D and Δ6-D activities, whereas the mRNA expression of both desaturases was enhanced over control values, changes that were prevented by concomitant AR-EVOO supplementation. N-6 and n-3 LCPUFAs were also decreased by IRD in extrahepatic tissues and normalized by AR-EVOO. In conclusion, AR-EVOO supplementation prevents IRD-induced changes in parameters related to liver FA metabolism and steatosis, an effect that may have a significant impact in the treatment of iron-related pathologies or metabolic disorders such as non-alcoholic fatty liver disease.

Abstract
There is accumulating evidence showing that apoptosis induced by endoplasmic reticulum (ER) stress plays a key role in pancreatic β cell dysfunction and insulin resistance. 3β-Hydroxysteroid-Δ24 Reductase (DHCR24) is a multifunctional enzyme located in the endoplasmic reticulum (ER), which has been previously shown to protect neuronal cells from ER stress-induced apoptosis. However, the role of DHCR24 in type 2 diabetes is only incompletely understood so far. In the present study, we induced ER stress by tunicamycin (TM) treatment and showed that infection of MIN6 cells with Ad-DHCR24-myc rendered these cells resistant to caspase-3-mediated apoptosis induced by TM, while cells transfected with siRNAs targeting DHCR24 were more sensitive to TM. Western blot analysis showed that TM treatment induced upregulation of Bip protein levels in both cells infected with Ad-LacZ (the control group) and Ad-DHCR24-myc, indicating substantial ER stress. Cells infected with Ad-LacZ exhibited a rapid and strong activation of ATF6 and p38, peaking at 3 h after TM exposure. Conversely, cells infected with Ad-DHCR24-myc showed a higher and more sustained activation of ATF6 and Bip than control cells. DHCR24 overexpression also inhibited the generation of intracellular reactive oxygen species (ROS) induced by ER stress and protected cells from apoptosis caused by treatment with both cholesterol and hydrogen peroxide. In summary, these data demonstrate, for the first time, that DHCR24 protects pancreatic β cells from apoptosis induced by ER stress.

Abstract
The augmenting acceptance and application of herbal medicine in prevention and treatment of diseases also involve the use of plant essential oils (EOs) through different routes of administration (aromatherapy). Scientific data supporting the efficacy of certain herbal products are continuously growing; however, the cumulative evidence is not always sufficient. The anti-inflammatory properties of EOs have been investigated more extensively and also reviewed in different settings, but so far, our review is the first to summarize the immune-supporting properties of EOs. Our aim here is to synthesize the currently available data on the immune function enhancing effects of EOs. An online search was conducted in the PubMed database, which was terminated at the end of July 2019. Other articles were found in the reference lists of the preselected papers. Studies that applied whole EOs with known components, or single EO constituents under in vitro or in vivo laboratory conditions, or in human studies, and de facto measured parameters related to immune function as outcome measures were included. Two specific fields, EO dietary supplementation for livestock and fish, and forest bathing are also explored. Some EOs, particularly eucalyptus and ginger, seem to have immune function enhancing properties in multiple studies.

Abstract
Oxidative stress leads to intestinal epithelial cells damage, which induces tight junction injury and systemic endogenous stress syndrome. The evidence suggests that SIRT1/PGC-1α pathway is closely associated with oxidative damage. However, the mechanism in protecting intestinal epithelial cells against oxidative stress dependant on autopahgy/mitophagy remains to be elucidated. In the current study, we investigated the functional role of SIRT1/PGC-1α pathway on regulation of autopahgy/mitophagy and tight junction protein expression underlying the oxidative dysfunction in porcine intestinal epithelial cells (IPEC-1). Results demonstrated that H2O2 exposure caused high accumulation of ROS, with a decrease of mitochondrial membrane potential and an inhibition of the tight junction molecules in IPEC-1 cells. Also, COX IV mRNA expression and SIRT1/PGC-1α pathway were suppressed. Autophagy and PINK1/Parkin dependant-mitophagy were activated following H2O2 treatment. Further research indicated that activation of SIRT1/PGC-1α pathway caused by specific activator SRT 1720 resulted in elevating autophagy/mitophagy related markers and SIRT1 inhibitor EX 527 reversed these effects. Additionally, SIRT1 activation significantly suppressed the ROS generation, leading to increase mitochondrial membrane potential and COX IV expression. Most importantly, the expression of tight junction molecules contributing to maintain intestinal barrier integrity was significantly up-regulated. Collectively, these findings indicated that autophagy/mitophagy elevation caused by SIRT1/PGC-1α pathway activation might be a protective mechanism to increase tight junction integrity against oxidative stress-mediated ROS production in IPEC-1 cells.

Abstract
Abstract
Background
The goal of this study was to explore the inherent antioxidant and antineoplastic activities of methanolic extract of the roots of Hibiscus sabdariffa (MEHSR).
Methods
The dried coarse powder of roots of Hibiscus sabdariffa was subjected to methanolic extraction. Here in vitro methods were used to determine the various types of phytochemical content and antioxidant activity of MEHSR as well as its cytotoxic effect against Ehrlich ascites carcinoma (EAC) cells. In vivo, antineoplastic activity of MEHSR against EAC cells was also evaluated by determining the viable tumor cell count, survival time, body weight gain, hematological profiles of experimental mice along with observing morphological changes of EAC cells by fluorescence microscope. Analysis of the chemical composition of MEHSR was carried out using GC-MS.
Results
Total phenolic and flavonoid contents of MEHSR were found to be 143.36 and 82.81 mg/g of extract in terms of gallic acid and catechin equivalent, respectively. The MEHSR exhibited very good scavenging property on DPPH (IC50: 13.37 μg/mL) and ABTS (IC50: 18.88 μg/mL) radicals in respect to nitric oxide (IC50: 72.82 μg/mL) radical and lipid peroxidation (IC50: 75.78 μg/mL) inhibition. MEHSR was found to induce Ehrlich ascites carcinoma (EAC) cell death at a dose dependent fashion. At dose 10 mg/kg, MEHSR significantly inhibited tumor cell growth rate (62.24%; p < 0.05), decreased tumor weight (57.81%; p < 0.05), increased life span (38.97%) compared to the untreated control mice. MEHSR also restored all hematological parameters of EAC-bearing mice towards normal level. Furthermore, administration of MEHSR induced apoptosis of EAC cells as observed in Hoechst 33342 stained cells under fluorescence microscope. Arachidic acid (49.18%), oleic acid (36.36%) and octadecanoic acid (14.47%) were identified as the major components of MEHSR by GC-MS analysis.
Conclusion
In a nutshell, our findings proposed that MEHSR may possess promising antioxidant and antineoplastic efficacy against Ehrlich ascites carcinoma cells by induction of cell apoptosis. Therefore, it might be a potent and novel candidate for anticancer therapy.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is a rising epidemic worldwide and will be the leading cause of cirrhosis, hepatocellular carcinoma, and liver transplant within the next decade. NAFLD is considered as the hepatic manifestation of metabolic syndrome. Behaviors, such as a sedentary lifestyle and consuming a Western diet, have led to substantial challenges in managing NAFLD patients. With no curative pharmaceutical therapies, lifestyle modifications, including dietary changes and exercise, that ultimately lead to weight loss remain the only effective therapy for NAFLD. Multiple diets, including low-carbohydrate, low-fat, Dietary Approaches to Stop Hypertension (DASH), and Mediterranean (MD) diets, have been evaluated. NAFLD patients have shown better outcomes with a modified diet, such as the MD diet, where patients are encouraged to increase the consumption of fruits and vegetables, whole grains, and olive oil. It is increasingly clear that a personalized approach to managing NAFLD patients, based on their preferences and needs, should be implemented. In our review, we cover NAFLD management, with a specific focus on dietary patterns and their components. We emphasize the successful approaches highlighted in recent studies to provide recommendations that health care providers could apply in managing their NAFLD patients.

Abstract
Introduction: Non-alcoholic fatty liver disease (NAFLD) is estimated to affect 25% of adult people worldwide. Nowadays, there is no definite treatment for NAFLD. International guidelines define an approach based on lifestyle changes, included a health alimentary regimen. The Mediterranean diet (MD) represents the gold standard in preventive medicine, probably due to the harmonic combination of many elements with antioxidant and anti-inflammatory properties. Its prescription is also recommended in patients with NAFLD. Olive oil, as part of MD, is associated with benefits on human health especially regarding the cardiovascular system, obesity, diabetes and related metabolic disorders. Areas covered: An overview of the beneficial effects of olive oil in the prevention and treatment of NAFLD is given. Expert opinion: A large body of evidence emphasizes that olive oil, used as primary source of fat in MD, may play a crucial role in the health benefits of NAFLD patients. However, there are still scarce clinical data that evaluate the direct effect of olive oil in human with NAFLD.
