Abstract
Mesenchymal stem cells (MSCs) are being developed for stem cell therapy and can be efficiently used in regenerative medicine. To date, more than 1,000 clinical trials have used MSCs; of these, more than 80 clinical trials have targeted liver disease. MSCs migrate to damaged liver tissues, differentiate into hepatocytes, reduce liver inflammatory responses, reduce liver fibrosis, and act as antioxidants. According to the reported literature, MSCs are safe, have no side effects, and improve liver function; however, their regenerative therapeutic effects are unsatisfactory. Here, we explain, in detail, the basic therapeutic effects and recent clinical advances of MSCs. Furthermore, we discuss future research directions for improving the regenerative therapeutic effects of MSCs.

Abstract
BACKGROUND Liver is one of the first organs to be exposed to reactive oxygen species (ROS). But the data about the levels of redox homeostasis parameters in the patients with liver cirrhosis (LC) are contradictory. We hypothesized that the levels of malondialdehyde and catalase should change in accordance with the LC severity causing the endothelial dysfunction. METHODS In a randomized way with the preliminary stratification by the presence of LC 81 patients and 20 healthy volunteers were examined. To determine the contents of catalase, malondialdehyde, cyclic guanosine monophosphate, endothelin-1, renin, aldosterone, natriuretic peptide, the routine standardized methods were used. RESULTS Patients with LC revealed the statistically significant increase of malondialdehyde and decrease of catalase levels in parallel with the increase of cyclic guanosine monophosphate, endothelin-1, renin, aldosterone, natriuretic peptide contents and disease course worsening according to the Child-Pugh criteria. It testifies the huge oxidative stress impact on the organism. Initially, at the stage of LC compensation, it slightly stimulates the activation of antioxidant system, followed by its gradual suppression at the stages of sub- and decompensation. Disorders of redox homeostasis lead to the endothelial dysfunction that becomes the background of extrahepatic comorbid disorders. CONCLUSIONS Cirrhotic patients have significant abnormalities in the redox homeostasis, which become the background of the endothelial dysfunction - common trigger mechanism for the syntrophic comorbid diseases and early pathophysiologic symptom of the unfavorable prognosis for such patients.

Abstract
BACKGROUND Myrin®-p Forte is an anti-tuberclosis agent that can cause hepatic injuries in clinical settings. Maytenus royleanus (Celastraceae) is a medicinal plant, possesses antioxidant and anticancer activities. The hepatoprotective effect of the methanol extract of Maytenus royleanus leaves (MEM) against Myrin®-p Forte induced hepatotoxicity in mice was investigated. METHODS Mice were randomly parted into six groups (n = 6). Fixed-dose combination of Myrin®-p Forte (13.5 mg/kg Rifampicin, 6.75 mg/kg Isoniazid, 36.0 mg/kg Pyrazinamide and 24.8 mg/kg Ethambutol; RIPE] was administered for 15 days to induce liver injury. In treatment groups MEM (200 mg/kg and 400 mg/kg doses) and Vitamin B6 (180mg/kg) were administered prior to RIPE. Control group received 2% DMSO. Serum liver function tests, DNA damage, tissue antioxidant enzymes and histopathological alterations were studied. HPLC analysis was performed to determine the chemical composition using standard compounds. RESULTS The quercitin, gallic acid, luteolin, viteixin, apigenin, kaempherol, hyperoside and myricetin contents of all samples were determined by reverse-phase HPLC. Quercetin (0.217 mg/g dry weight) and luteolin (0.141 mg/g dry weight) were the major flavonoids identified in MEM. Myrin®-p Forte markedly (p < 0.05) deteriorated lipid profile and upregulated the concentration of LDH, AST, ALP, ALT and γ-GT in serum along with DNA fragmentation (37.13 ± 0.47%) and histopathological injuries in hepatic tissues of mice compared with the control group. Myrin®-p Forte increased (p < 0.001) lipid peroxidation and H2O2 while decreased (p < 0.001) the activity level of CAT, SOD, POD, GPx, GST, GSR, γ-GT and GSH. Co-administration of MEM (200 mg/kg; 400 mg/kg) or the vitamin B6 (180 mg/kg) to Myrin®-p Forte administered mice significantly ameliorated LDL, cholesterol, HDL and triglyceride content. Furthermore, MEM dose dependently corrected serum liver function tests, decrease % DNA fragmentation (17.82 ± 0.35 and 7.21 ± 0.32 respectively), DNA damage. MEM treated protect RIPE induced oxidative damage by enhancing antioxidants to oxidants balance. Histological examination comprehends biochemical findings. CONCLUSION The antioxidant effects of MEM exerted the hepatoprotective potential against the Myrin®-p Forte induced hepatotoxicity in mice.

Abstract
The aim of this study was to compare the protective effects of chokeberry juice and silymarin against chemical-induced liver fibrosis in rats. Liver fibrosis was induced by CCl4 administered two days a week for six weeks. Two groups of rats were co-treated with chokeberry juice, 10 mL/kg/day. or silymarin as a positive control, 100 mg/kg/day for six weeks. Hepatic lipid peroxidation was suppressed by 50% and the activity of hepatic antioxidant enzymes was increased by 19%–173% in rats co-treated with CCl4 and substances tested as compared to rats administered CCl4 alone. Hepatic hydroxyproline was decreased by 24% only in rats treated with silymarin. The messenger RNA (mRNA) expression levels of fibrosis-related molecules, procollagen I, α-SMA, TIMP-1, TGFβ, and TNFα, which were significantly increased in the liver of CCl4-treated rats, were not modulated by substances tested. Histological evaluation revealed a slight protective effect of silymarin against fibrosis. However, in CCl4 + chokeberry-treated rats, the density of vacuolated hepatocytes was significantly lower than that in silymarin administered animals. Chokeberry juice did not demonstrate an antifibrotic effect in the applied experimental model of fibrosis, and the effect of the known antifibrotic agent, silymarin, was very limited.

Abstract
The prevalence of nonalcoholic fatty liver is increasing due to modern lifestyle. Germinated and dehulled Macrotyloma uniflorum and Vigna radiate were shown to have enhanced nutrients. Curcuma longa and Trigonella foenum graecum were proven hepatoprotective.The supplementation of the nutrient herbal mixture to the MCD diet-induced steatosis shows reduced hepatic fat accumulation and lipid profile, and liver injury markers in serum also reserved in normal. Increased serum albumin in the treatment group indicates that the liver function is enhanced than that of steatosis. The supplementation of the herbal mixture has preserved the hepatic antioxidant. Zymographic analysis of matrix metalloproteinase, western blot determination of α-SMA, and histological evolution (H&E, Sirius red) depicted reduced fibrosis and reveled management of hepatic stellate cells in quiescent form. The present study concludes that the herbal mixture has reduced hepatocyte fat accumulation in steatotic animals, and curtailed the oxidative stress, further it prevents the progression of steatohepatitis. PRACTICAL APPLICATIONS: Fatty liver diseases can be treated by modulating the diet composition such as consuming food rich in the nutrient herbal mixture. In this study, the nutrient mixture was made with dynamic food processing techniques such as germination, dehulling, and milling to augment the nutritional contents. Besides, Macrotyloma uniflorum, Vigna radiate, Curcuma longa, and Trigonella foenum graecum were used to improve the medicinal value and antioxidant. This formulation could target the various stages of NAFLD. This study revealed that the nutrient herbal mixture reduces the steatosis of the liver and curtailed the progression of steatohepatitis from hepatic steatosis. Since the edible foodstuff was used to make the nutrient mixture, it has excellent clinical application.

Abstract
In liver cirrhosis, oxidative stress plays a major role in promoting liver inflammation and fibrosis. Mitochondria dysregulation is responsible for excessive reactive oxygen species production. Therefore, in an experimental model of cirrhosis, we investigated the effect of mitochondria-targeted antioxidant mitoquinone. Liver cirrhosis was induced in Spraque-Dawley rats by common bile duct ligation (CBDL). Mitoquinone (10 mg·kg-1·day-1, oral gavage) or vehicle was administered from 3rd to 28th day after CBDL, when animals were euthanized; liver oxidative stress, inflammation, fibrosis, mitophagy were evaluated; and in vivo and ex vivo hemodynamic studies were performed. In cirrhotic rats, mitoquinone prevented liver inflammation, hepatocyte necrosis, and fibrosis at histological examination; decreased circulating TNF-α, gene expression of transforming growth factor-β1, collagen type 1a1, TNF-α, IL-6, IL-1β, tissue inhibitor of metalloproteinase-1, matrix metalloproteinase (MMP)-2, and MMP-13; and reduced hepatic oxidative stress, as shown by reduced oxidative carbonylation of the proteins, by modulating antioxidants catalase, Mn superoxide dismutase, and Cu/Zn superoxide dismutase. Furthermore, mitoquinone attenuated apoptosis by reducing hepatic protein expression of cleaved caspase-3. A selective removal of dysfunctional mitochondria was improved by mitoquinone, as shown by the increase in Parkin translocation to mitochondria. Treatment with mitoquinone normalized the weight of the spleen; however, it increased portal blood flow and reduced splenic artery intrahepatic resistance, suggesting an effect on resistance index. Mitochondria-targeted antioxidant mitoquinone improves liver inflammation and fibrosis in cirrhotic rats by reducing hepatic oxidative stress, preventing apoptosis, and promoting removal of dysfunctional mitochondria. Therefore, it may represent a promising strategy for the prevention and treatment of liver cirrhosis.

Abstract
BACKGROUND AND AIM Liver fibrosis is a leading cause of mortality worldwide. Oxidative stress is a key component in the pathogenesis of liver fibrosis. We investigated the role of aldehyde formation resulting from lipid peroxidation in cholestatic liver injury and fibrosis. METHODS C57Bl/6J mice underwent bile duct ligation (BDL) or sham operation. One hour after surgery and daily thereafter, animals were given Alda-1 (20 mg/kg, s.c.), an aldehyde dehydrogenase-2 activator, or equivalent volume of vehicle. Blood and livers were collected after 3 and 14 days. RESULTS Serum alanine aminotransferase (ALT) increased from 39.8 U/L after sham operation to 537 U/L 3 days after BDL, which Alda-1 decreased to 281 U/L. Biliary infarcts with a periportal distribution developed with an area of 7.8% at 14 days after BDL versus 0% area after sham operation. Alda-1 treatment with BDL decreased biliary infarcts to 1.9%. Fibrosis detected by picrosirius red staining increased from 1.6% area in sham to 7.3% after BDL, which decreased to 3.8% with Alda-1. Alda-1 suppression of fibrosis was additionally confirmed by second harmonic generation microscopy. After BDL, collagen-I mRNA increased 12-fold compared to sham, which decreased to 6-fold after Alda-1 treatment. Smooth muscle α-actin expression in the liver, a marker of activated stellate cells, increased from 1% area in sham to 18.7% after BDL, which decreased to 5.3% with Alda-1. CD68-positive macrophages increased from 33.4 cells/field in sham to 134.5 cells/field after BDL, which decreased to 64.9 cells/field with Alda-1. Lastly, 4-hydroxynonenal adduct (4-HNE) immunofluorescence increased from 2.5% area in sham to 14.1% after BDL. Alda-1 treatment decreased 4-HNE to 2.2%. CONCLUSION Accelerated aldehyde degradation by Alda-1 decreases BDL-induced liver necrosis, inflammation, and fibrosis, implying that aldehydes play an important role in the pathogenesis of cholestatic liver injury and fibrosis.

Abstract
mTORC1 is a protein kinase important for metabolism and is regulated by growth factor and nutrient signaling pathways, mediated by the Rheb and Rag GTPases, respectively. Here we provide the first animal model in which both pathways were upregulated through concurrent mutations in their GTPase-activating proteins, Tsc1 and Depdc5. Unlike former models that induced limited mTORC1 upregulation, hepatic deletion of both Tsc1 and Depdc5 (DKO) produced strong, synergistic activation of the mTORC1 pathway and provoked pronounced and widespread hepatocyte damage, leading to externally visible liver failure phenotypes, such as jaundice and systemic growth defects. The transcriptome profile of DKO was different from single knockout mutants but similar to those of diseased human livers with severe hepatitis and mouse livers challenged with oxidative stress-inducing chemicals. In addition, DKO liver cells exhibited prominent molecular pathologies associated with excessive endoplasmic reticulum (ER) stress, oxidative stress, DNA damage and inflammation. Although DKO liver pathologies were ameliorated by mTORC1 inhibition, ER stress suppression unexpectedly aggravated them, suggesting that ER stress signaling is not the major conduit of how hyperactive mTORC1 produces liver damage. Interestingly, superoxide scavengers N-acetylcysteine (NAC) and Tempol, chemicals that reduce oxidative stress, were able to recover liver phenotypes, indicating that mTORC1 hyperactivation induced liver damage mainly through oxidative stress pathways. Our study provides a new model of unregulated mTORC1 activation through concomitant upregulation of growth factor and nutrient signaling axes and shows that mTORC1 hyperactivation alone can provoke oxidative tissue injury.

Abstract
Background The objective of our research was to assess the possible link between diabetes mellitus (DM) and liver cirrhosis in chronic hepatitis B (CHB) patients in Wuhan, China. Material/Methods Individuals with a diagnosis of both liver cirrhosis and chronic HBV infection (n=257), and CHB-only patients (n=514) were matched 1: 2 by age and sex. Demographic, lifestyle, laboratory, and clinical characteristics were reviewed. Univariate and the multiple logistic regression analysis were conducted to investigate the association between DM and HBV-related liver cirrhosis. Results The prevalence of DM was higher among CHB patients with liver cirrhosis than in those without liver cirrhosis (22.2% vs. 12.8%, P=0.001), yielding an adjusted odds ratio (AOR) of 2.317 and a 95% confidence interval (CI) of 1.528–3.513. Among them, 87.7% of liver cirrhosis patients were diagnosed with DM before liver cirrhosis diagnosis, yielding an AOR (95% CI) of 2.386 (1.533–3.714). In comparison to patients with a DM duration of 2–5 years, the AOR (95% CI) for those with a DM duration >5 years was 2.073 (0.701–6.132). In DM treatment, the AOR (95% CI) for those treated with insulin was 4.746 (1.329–16.949). Conclusions DM was associated with cirrhosis risk in CHB patients in Wuhan, China.

Abstract
The liver is the central metabolic organ of mammals. In humans, most diseases of the liver are primarily caused by an unhealthy lifestyle-high fat diet, drug and alcohol consumption- or due to infections and exposure to toxic substances like aflatoxin or other environmental factors. All these noxae cause changes in the metabolism of functional cells in the liver. In this literature review we focus on the changes at the miRNA level, the formation and impact of reactive oxygen species and the crosstalk between those factors. Both, miRNAs and oxidative stress are involved in the multifactorial development and progression of acute and chronic liver diseases, as well as in viral hepatitis and carcinogenesis, by influencing numerous signaling and metabolic pathways. Furthermore, expression patterns of miRNAs and antioxidants can be used for biomonitoring the course of disease and show potential to serve as possible therapeutic targets.

JOURNAL OF HAZARDOUS MATERIALS 2019; 378:120766. [PMID: 31226595 DOI: 10.1016/j.jhazmat.2019.120766] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/27/2019] [Revised: 06/07/2019] [Accepted: 06/11/2019] [Indexed: 06/09/2023]
Abstract
Exposure to polybrominated diphenyl ethers (PBDEs), is closely associated with the occurrence of obesity and non-alcoholic fatty liver disease (NAFLD), yet their pathological effects and underlying mechanisms remain unclear. To examine the role of 2, 2', 4, 4'-tetrabromodiphenyl ether (BDE-47) in the progression of NAFLD under obese condition, male C57BL/6 J mice were fed with diet interaction for 15 weeks and subcutaneously injected with BDE-47 (7 mg/kg or 70 mg/kg) or the vehicle weekly. BDE-47 exposure (70 mg/kg) significantly elevated the body weight and worsened hepatic steatosis along with increased inflammation in high fat diet (HFD) fed mice. Furthermore, integration analysis of lipidomics and gene expression revealed that BDE-47 up-regulated triglyceride synthesis but suppressed lipid exportation and β oxidation, aggravating the accumulation of hepatic lipid in HFD fed mice. In addition, the increase of liver fibrosis, serum transaminase levels, as well as lipid peroxidation have been observed in mice co-treated with BDE-47 and HFD. Moreover, BDE-47-induced fibrogenic responses in hepatocytes were suppressed by antioxidants, which confirmed that BDE-47-induced liver fibrosis was tightly associated with oxidative stress. In conclusion, these results provided new and robust evidence for revealing the hepatoxicity of BDE-47 under obese condition and illustrated the underlying mechanism of BDE-47 induced liver fibrosis.

Abstract
Hyperglycemia and hyperinsulinemia activate the proliferative potential of hepatic stellate cells (HSCs) and promote hepatic fibrosis. Dipeptidyl peptidase-4 (DPP-4) inhibitors, antidiabetic agents, reportedly inhibit the HSC proliferation. Additionally, Takeda G protein-coupled receptor 5 (TGR5) agonists induce the systemic release of glucagon-like peptides from intestinal L cells, which maintains glycemic homeostasis. This study assessed the combined effect of TGR5 agonist and DPP-4 inhibitor on diabetes-based liver fibrosis development. Male diabetic rats received intraperitoneal injection of porcine serum (PS) to induce liver fibrosis, and they were orally administered the following agents: oleanolic acid (OA) as a TGR5 agonist, anagliptin (ANA) as a DPP-4 inhibitor, and a combination of both agents. Treatment with OA or ANA significantly improved glycemic status and attenuated intrahepatic steatosis and lipid peroxidation in diabetic rats. PS-induced liver fibrosis development was also drastically suppressed by treatment with either agent, and the combination of both reciprocally enhanced the antifibrotic effect. Fecal microbiome demonstrated that both agents inhibited the increase in the Firmicutes/Bacteroidetes ratio, an indicator of dysbiosis related to metabolic syndromes. Furthermore, ANA directly inhibited in vitro HSC proliferative and profibrogenic activities. Collectively, TGR5 agonist and DPP-4 inhibitor appears to be a novel strategy against liver fibrosis under diabetic conditions.

Abstract
Diabetes mellitus has been on a continual rise as one of the top chronic diseases to affect individuals worldwide. The goal of this study was to determine how exposure from a well-known toxicant, a polycyclic aromatic hydrocarbon called 2-aminoanthracene (2AA), could potentially lead to diabetes, damage the liver, and have negative effects to the offspring. Humans are exposed to 2AA from foods cooked in high heat and tobacco smoke, among others. To analyze the effects of 2AA, three groups of Sprague Dawley dams consumed an adulterated 2AA diet from gestation to their postnatal period. Timed-pregnant dams ingested 0 mg/kg (control group (C)), 50 mg/kg (low dose group (LD)), and 100 mg/kg (high dose group (HD)) 2AA. Hepatic gene expressions of Adam8, Bax, Ccng1, CD68, CD93, Cdkn1c, and Ddit4 indicated a significant overexpression of Bax, Ccng1, CD68, CD93, and Cdkn1c in treated groups. Although there was no significant difference in the damage to the liver architecture by 2AA, the positively stained CD68+ cells were slightly increased in treated rats. Significant decreases in the albumin and aspartate aminotransferase levels might indicate an inflammatory response from 2AA exposure in dams. Immunoglobulin A (IgA) concentration was also decreased, in contrast to studies of liver cirrhosis that reported increased serum IgA concentration. Overexpression of genes Ddit4, Cdkn1c, Ccng1, Bax, CD93, and CD68 point to hepatic inflammation and apoptosis. Overall results suggest a link between environmental 2AA exposure and adverse liver effects, which has potential to increase susceptibility to type 2 diabetes and other diseases.

Abstract
Hepatic iron overload is one of the causative factors for chronic liver injury and fibrosis. The present study aimed to investigate the potential antifibrotic effect of the iron chelator; deferasirox (DFX) in experimentally-induced liver fibrosis in rats. Male Sprague-Dawley rats were administered concanavalin A (Con A) and/or DFX for 6 consecutive weeks. Con A injection induced significant hepatotoxicity as was evident by the elevated transaminases activity, and decreased albumin level. Also, it disturbed the iron homeostasis through increasing C/EBP homologous protein (CHOP), decreasing phosphorylated cAMP responsive element binding protein(P-CREB) and hepcidin levels leading to significant serum and hepatic iron overload. In addition, it induced an imbalance in the oxidative status of the liver via upregulating NADPH oxidase 4 (NOX4), together with a marked decrease in anti-oxidant enzymes' activities. As a consequence, upregulation of nuclear factor-kappa b (NF-κB) and the downstream inflammatory mediators was observed. Those events all together precipitated in initiation of liver fibrosis as confirmed by the elevation of alpha-smooth muscle actin (α-SMA) and liver collagen content. Co-treatment with DFX protected against experimentally-induced liver fibrosis in rats via its iron chelating, anti-oxidant, and anti-inflammatory properties. These findings imply that DFX can attenuate the progression of liver fibrosis.

Pirfenidone prevents and reverses hepatic insulin resistance and steatohepatitis by polarizing M2 macrophages. J Transl Med 2019; 99:1335-1348.

Abstract
Nonalcoholic steatohepatitis (NASH) is associated with lipotoxic liver injury, leading to insulin resistance, inflammation, and fibrosis. Despite its increased global incidence, very few promising treatments for NASH are available. Pirfenidone is an antifibrotic agent used to treat pulmonary fibrosis; it suppresses the pulmonary influx of T cells and macrophages. Here, we investigated the effect of pirfenidone in a mouse model of lipotoxicity-induced NASH via a high-cholesterol and high-fat diet. After 12 weeks of feeding, pirfenidone administration attenuated excessive hepatic lipid accumulation and peroxidation by reducing the expression of genes related to lipogenesis and fatty acid synthesis and enhancing the expression of those related to fatty acid oxidation. Flow cytometry indicated that pirfenidone reduced the number of total hepatic macrophages, particularly CD11c+CD206-(M1)-type macrophages, increased the number of CD11c-CD206+(M2)-type macrophages, and subsequently reduced T-cell numbers, which helped improve insulin resistance and steatohepatitis. Moreover, pirfenidone downregulated the lipopolysaccharide (LPS)-induced mRNA expression of M1 marker genes and upregulated IL-4-induced M2 marker genes in a dose-dependent manner in RAW264.7 macrophages. Importantly, pirfenidone reversed insulin resistance, hepatic inflammation, and fibrosis in mice with pre-existing NASH. These findings suggest that pirfenidone is a potential candidate for the treatment of NASH.

A novel role of glutathione S-transferase A3 in inhibiting hepatic stellate cell activation and rat hepatic fibrosis. J Transl Med 2019; 17:280.

Abstract
Background and aims Glutathione S-transferase A3 (GSTA3) is known as an antioxidative protease, however, the crucial role of GSTA3 in liver fibrosis remains unclear. As a recently we developed water-soluble pyridone agent with antifibrotic features, fluorofenidone (AKF-PD) can attenuate liver fibrosis, present studies were designed to explore the role of GSTA3 in liver fibrosis and its modulation by AKF-PD in vivo and in vitro. Methods Rats liver fibrosis models were induced by dimethylnitrosamine (DMN) or carbon tetrachloride (CCl4). The two activated hepatic stellate cells (HSCs) lines, rat CFSC-2G and human LX2 were treated with AKF-PD respectively. The lipid peroxidation byproduct malondialdehyde (MDA) in rat serum was determined by ELISA. The accumulation of reactive oxygen species (ROS) was measured by dichlorodihydrofluorescein fluorescence analysis. The expression of α-smooth muscle actin (α-SMA), fibronectin (FN), and phosphorylation of extracellular signal-regulated kinase1/2 (ERK1/2), p38 mitogen-activated protein kinase (p38 MAPK), c-Jun N-terminal kinase (JNK) and glycogen synthase kinase 3 beta (GSK-3β) were detected by western blotting (WB). Results GSTA3 was substantially reduced in the experimental fibrotic livers and transdifferentiated HSCs. AKF-PD alleviated rat hepatic fibrosis and potently inhibited HSCs activation correlated with restoring GSTA3. Moreover, GSTA3 overexpression prevented HSCs activation and fibrogenesis, while GSTA3 knockdown enhanced HSCs activation and fibrogenesis resulted from increasing accumulation of ROS and subsequent amplified MAPK signaling and GSK-3β phosphorylation. Conclusions We demonstrated firstly that GSTA3 inhibited HSCs activation and liver fibrosis through suppression of the MAPK and GSK-3β signaling pathways. GSTA3 may represent a promising target for potential therapeutic intervention in liver fibrotic diseases.

Estrogen Deficiency Potentiates Thioacetamide-Induced Hepatic Fibrosis in Sprague-Dawley Rats. Int J Mol Sci 2019; 20:ijms20153709.

Abstract
Hepatic fibrosis is characterized by persistent deposition of extracellular matrix proteins and occurs in chronic liver diseases. The aim of the present study is to investigate whether estrogen deficiency (ED) potentiates hepatic fibrosis in a thioacetamide (TAA)-treated rat model. Fibrosis was induced via intraperitoneal injection (i.p.) of TAA (150 mg/kg/day) for four weeks in ovariectomized (OVX) female, sham-operated female, or male rats. In TAA-treated OVX rats, the activities of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and γ-glutamyl transferase (GGT) were significantly increased compared to those in TAA-treated sham-operated OVX rats or TAA-treated male rats. Furthermore, α-smooth muscle actin (α-SMA) expression was significantly increased compared to that in TAA-treated sham-operated rats. This was accompanied by the appearance of fibrosis biomarkers including vimentin, collagen-I, and hydroxyproline, in the liver of TAA-treated OVX rats. In addition, ED markedly reduced total glutathione (GSH) levels, as well as catalase (CAT) and superoxide dismutase (SOD) activity in TAA-treated OVX rats. In contrast, hepatic malondialdehyde (MDA) levels were elevated in TAA-treated OVX rats. Apoptosis significantly increased in TAA-treated OVX rats, as reflected by elevated p53, Bcl-2, and cleaved caspase 3 levels. Significant increases in interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) concentrations were exhibited in TAA-treated OVX rats, and this further aggravated fibrosis through the transforming growth factor-β (TGF-β)/Smad pathway. Our data suggest that ED potentiates TAA-induced oxidative damage in the liver, suggesting that ED may enhance the severity of hepatic fibrosis in menopausal women.

Abstract
Aims: Hepatic fibrosis results from chronic liver injury and inflammatory responses. Sestrin 2 (Sesn2), an evolutionarily conserved antioxidant enzyme, reduces the severities of acute hepatitis and metabolic liver diseases. However, the role of Sesn2 in the pathogenesis of liver fibrosis remains obscure. Here, we used cultured hepatic stellate cells (HSCs) and chronic carbon tetrachloride (CCl4) and bile duct ligation (BDL) murine models to investigate the effects of Sesn2 on fibrogenesis. Results: Sesn2 protein and mRNA levels were upregulated in activated primary HSCs, and by increasing transcription, transforming growth factor-β (TGF-β) also increased Sesn2 expression in HSCs. Furthermore, Smad activation was primarily initiated by TGF-β signaling, and Smad3 activation increased Sesn2 luciferase activity. In silico analysis of the 5' upstream region of the Sesn2 gene revealed a putative Smad-binding element (SBE), and its deletion demonstrated that the SBE between -964 and -956 bp within human Sesn2 promoter was critically required for TGF-β-mediated response. Moreover, ectopic expression of Sesn2 reduced gene expressions associated with HSC activation, and this was accompanied by marked decreases in SBE luciferase activity and Smad phosphorylation. Infection of recombinant adenovirus Sesn2 reduced hepatic injury severity, as evidenced by reductions in CCl4- or BDL-induced alanine aminotransferase and aspartate aminotransferase, and inhibited collagen accumulation. Furthermore, HSC-specific lentiviral delivery of Sesn2 prevented CCl4-induced liver fibrosis. Finally, Sesn2 expression was downregulated in the livers of patients with liver cirrhosis and in mouse models of hepatic fibrosis. Innovation and Conclusion: Our findings suggest that Sesn2 has the potential to inhibit HSC activation and hepatic fibrosis.

Abstract
This work investigated the protective effects of Ganoderma applanatum residue polysaccharides (GRP) on the CCl4-induced hepatotoxicity. The results indicated that GRP showed significantly effects on preventing the increase of AST, ALT and ALP levels in serum, elevating the activities of SOD, GSH-Px and CAT, decreasing the contents of MDA and LPO, and reducing the CYP2E1 and TGF-β concentrations in CCl4-induced mice, respectively. Meanwhile, the levels of TNF-α and IL-6 were significantly decreased, while the value of IL-10 was increased by GRP treatment. Besides, the western blot assay showed the IκBα expressions were significantly increased and the p-p65 was decreased by the treatment with GRP. The characterizations indicated that the GRP was heteropolysaccharide with lower molecular weights and α-furanoside residues. These results demonstrated that GRP might be a potential material for drug and functional food development against chemical hepatic injury.

Abstract
Background Proline is a proteinogenic amino acid with multiple biological functions. Several investigations have been supposed that cellular proline accumulation is a stress response mechanism. This amino acid acts as an osmoregulator, scavenges free radical species, boosts cellular antioxidant defense mechanisms, protects mitochondria, and promotes energy production. The current study was designed to investigate the effect of proline treatment on the liver in bile duct ligated (BDL) rats as an animal model of cholestasis/cirrhosis. Methods BDL rats were supplemented with proline-containing drinking water (0.25% and 0.5% w:v), and samples were collected at scheduled time intervals (3, 7, 14, 28, and 42 days after BDL surgery). Results Drastic elevation in the serum level of liver injury biomarkers and significant tissue histopathological changes were evident in BDL rats. Markers of oxidative stress were also higher in the liver of BDL animals. It was found that proline supplementation attenuated BDL-induced alteration in serum biomarkers of liver injury, mitigated liver histopathological changes, and alleviated markers of oxidative stress at the early stage of BDL operation (3, 7, and 14 days after BDL surgery). Conclusions The hepatoprotection provided by proline in BDL animals might be associated with its ability to attenuate oxidative stress and its consequences.

Abstract
Alcoholic liver disease (ALD) refers to the damages to the liver and its functions due to alcohol overconsumption. It consists of fatty liver/steatosis, alcoholic hepatitis, steatohepatitis, chronic hepatitis with liver fibrosis or cirrhosis, and hepatocellular carcinoma. However, the mechanisms behind the pathogenesis of alcoholic liver disease are extremely complicated due to the involvement of immune cells, adipose tissues, and genetic diversity. Clinically, the diagnosis of ALD is not yet well developed. Therefore, the number of patients in advanced stages has increased due to the failure of proper early detection and treatment. At present, abstinence and nutritional therapy remain the conventional therapeutic interventions for ALD. Moreover, the therapies which target the TNF receptor superfamily, hormones, antioxidant signals, and MicroRNAs are used as treatments for ALD. In particular, mesenchymal stem cells (MSCs) are gaining attention as a potential therapeutic target of ALD. Therefore, in this review, we have summarized the current understandings of the pathogenesis and diagnosis of ALD. Moreover, we also discuss the various existing treatment strategies while focusing on promising therapeutic approaches for ALD.

Abstract
Fibrogenic progression of chronic liver disease, whatever the etiology, is characterized by persistent chronic parenchymal injury, chronic activation of inflammatory response, and sustained activation of liver fibrogenesis, and of pathological wound healing response. A critical role in liver fibrogenesis is played by hepatic myofibroblasts (MFs), a heterogeneous population of α smooth-muscle actin—positive cells that originate from various precursor cells through a process of activation and transdifferentiation. In this review, we focus the attention on the role of extracellular signal-regulated kinase (ERK) signaling pathway as a critical one in modulating selected profibrogenic phenotypic responses operated by liver MFs. We will also analyze major therapeutic antifibrotic strategies developed in the last two decades in preclinical studies, some translated to clinical conditions, designed to interfere directly or indirectly with the Ras/Raf/MEK/ERK signaling pathway in activated hepatic MFs, but that also significantly increased our knowledge on the biology and pathobiology of these fascinating profibrogenic cells.

Abstract
BACKGROUND Doxorubicin (DOX) is an anthracycline agent mostly prescribed for various cancers. However, its treatment is contiguous with toxic effects. Acacia hydaspica prevented drug-induced hepatic-toxicity in animals with anti-oxidative mechanisms. We intended to study the efficacy of A. hydaspica ethyl acetate extract (AHE) for inhibiting DOX- induced liver damage. METHODS Normal control group received saline; Drug control group received 3 mg/kg b.w. dose of DOX for 6 weeks (single dose/week, intraperitoneal injection) to study the effect of chronic DOX treatment. In co-treatment groups, 200 and 400 mg/kg b.w AHE was given orally for 6 weeks in concomitant with DOX (3 mg/kg b.w, i.p. injection per week). The standard drug group received silyamrin 100 mg/kg b.w (2 doses/week: 12 doses/6 weeks) in conjunction with DOX (single dose/week). Lipid profile, liver function tests (LFTs), antioxidant enzymes, oxidative stress enzymes and morphological alterations were studied to evaluate the hepatoprotective potential of AHE. RESULTS DOX treatment inhibits body weight gain and upturn liver index. DOX considerably upset serum cholesterol, triglycerides and LDL concentration. On the contrary, it reduced serum HDL amount. DOX induced marked depreciation in serum LFTs, diminish hepatic antioxidant enzymes; however, raised tissue oxidative stress markers accompanied by morphological damages. Co-treatment with AHE dose dependently adjusted DOX-prompted fluctuations in lipid profile, AST, ALP, ALT, total bilirubin, and direct bilirubin concentrations and hepatic weight. Likewise, AHE usage enhanced total protein and hepatic tissue antioxidant enzyme quantities whereas declined oxidative stress markers in hepatic tissue. Correspondingly histopathological examinations aid the biochemical results. The influence of AHE 400 mg/kg b.w dose is analogous to silymarin. CONCLUSION Acacia hydaspica possibly serve as adjuvant therapy that hampers DOX inveigled liver damage due to the underlying antioxidant mechanism of secondary metabolites.

Abstract
Many animal experiments and clinical trials showed that probiotics are effective for the treatment of alcoholic liver disease. Alcohol disrupts the composition of intestinal flora; probiotics modulate the gut microbiota and reverse alcohol-associated intestinal barrier dysfunction by decreasing intestinal mucosal permeability and preventing intestinal bacteria from translocating. Probiotics enhance immune responses and reduce the levels of alcohol-induced inflammatory cytokines and reactive oxygen species (ROS) production in the liver and intestine. Probiotics also increase fatty acid β-oxidation and reduce lipogenesis, combating alcohol-induced hepatic steatosis. In this review, we summarize the current knowledge regarding the mechanism of action of probiotics for reducing the effects of alcoholic liver disease.

Abstract
Oxidative stress is a reflection of the imbalance between the production of reactive oxygen species (ROS) and the scavenging capacity of the antioxidant system. Excessive ROS, generated from various endogenous oxidative biochemical enzymes, interferes with the normal function of liver-specific cells and presumably plays a role in the pathogenesis of liver fibrosis. Once exposed to harmful stimuli, Kupffer cells (KC) are the main effectors responsible for the generation of ROS, which consequently affect hepatic stellate cells (HSC) and hepatocytes. ROS-activated HSC undergo a phenotypic switch and deposit an excessive amount of extracellular matrix that alters the normal liver architecture and negatively affects liver function. Additionally, ROS stimulate necrosis and apoptosis of hepatocytes, which causes liver injury and leads to the progression of end-stage liver disease. In this review, we overview the role of ROS in liver fibrosis and discuss the promising therapeutic interventions related to oxidative stress. Most importantly, novel drugs that directly target the molecular pathways responsible for ROS generation, namely, mitochondrial dysfunction inhibitors, endoplasmic reticulum stress inhibitors, NADPH oxidase (NOX) inhibitors, and Toll-like receptor (TLR)-affecting agents, are reviewed in detail. In addition, challenges for targeting oxidative stress in the management of liver fibrosis are discussed.

Abstract
Polyphenols derived from green tea have been reported to have a wide range of profound functions. Tea catechins, including epicatechin, epigallocatechin (EGC), epicatechin-3- O-gallate (ECG), and epigallocatechin-3- O-gallate (EGCG), are considered as the major bioactive polyphenols in tea. The present study was designed to elucidate the potential antifibrogenic role of three abundant tea catechins (ECG, EGC, and EGCG) in a CCl4-induced fibrotic rat and their underlying molecular mechanisms. Tea catechins, especially groups of ECG, EGC, and EGCG, effectively induced several beneficial alterations of liver injury markers, oxidative status, and liver histology. Furthermore, catechins ameliorated liver fibrosis, as evidenced by the reduced expression of desmin, α-smooth muscle actin, transforming growth factor β (TGF-β), and downstream ERK1/2 and Smad1/2 phosphorylation. The most significant inhibitory effect on those proteins was observed in ECG (300 mg/kg) and EGCG (300 mg/kg) groups. In addition, catechins conferred their protective role by downregulating the proinflammation cytokines TGF-β, tumor necrosis factor α, and interleukin 17. It is postulated that tea catechins, particularly ECG and EGCG, are potential therapeutic candidates in antifibrotic therapy.

Abstract
Triclosan (TCS), an extensively used antimicrobial agent, has raised considerable concern due to its hepatocarcinogenic potential. However, previous hepatotoxicity studies primarily focused on the activation of specific intracellular receptors, the underlying mechanisms still warrant further investigation at the metabolic level. Herein, we applied metabolomics in combination with lipidomics to unveil TCS-related metabolic responses in human normal and cancerous hepatocytes. Endogenous and exogenous metabolites were analyzed for the identification of metabolic biomarkers and biotransformation products. In L02 normal cells, TCS exposure induced the up-regulation of purine metabolism and amino acid metabolism, caused lipid accumulation, and disturbed energy metabolism. These metabolic disorders in turn enhanced the overproduction of reactive oxygen species (ROS), leading to the alteration of antioxidant enzyme activities, down-regulation of endogenous antioxidants, and peroxidation of lipids. TCS-induced oxidative stress is thus considered to be one crucial factor for hepatotoxicity. However, in HepG2 cancer cells, TCS underwent fast detoxification through phase II metabolism, accompanied by the enhancement of energy metabolism and elevation of antioxidant defense system, which contributed to the potential effects of TCS on human hepatocellular carcinoma development. These different responses of metabolism between normal and cancerous hepatocytes provide novel and robust perspectives for revealing the mechanisms of TCS-triggered hepatotoxicity.

Abstract
The aim of the present research was to study the therapeutic impacts of fluorofenidone (AKF-PD) on pig serum (PS)-induced liver fibrosis in rats and the complex molecular mechanisms of its effects on hepatic stellate cells (HSCs). Wistar rats were randomly divided into normal control, PS and PS/AKF-PD treatment groups. The activated human HSC LX-2 cell line was also treated with AKF-PD. The expression of collagen I and III, and α-smooth muscle actin (α-SMA) was determined by immunohistochemical staining and reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Western blotting and/or RT-qPCR analyses were used to determine the expression of transforming growth factor (TGF)-β1, α-SMA, collagen I, mothers against decapentaplegic homolog (Smad)-3, extracellular signal-regulated kinase (ERK)1/2, p38 mitogen-activated protein kinase (p38 MAPK) and c-Jun N-terminal kinase (JNK). AKF-PD attenuated the degree of hepatic fibrosis and liver injury in vivo, which was associated with the downregulation of collagen I and III, and α-SMA at the mRNA and protein levels. In vitro, AKF-PD treatment significantly reduced the TGF-β1-induced activation of HSCs, as determined by the reduction in collagen I and α-SMA protein expression. The TGF-β1-induced upregulation of the phosphorylation of Smad 3, ERK1/2, p38 and JNK was attenuated by AKF-PD treatment. These findings suggested that AKF-PD attenuated the progression of hepatic fibrosis by suppressing HSCs activation via the TGF-β1/Smad and MAPK signaling pathways, and therefore that AKF-PD may be suitable for use as a novel therapeutic agent against liver fibrosis.

Abstract
The fruits, leaves, and roots of Cudrania tricuspidata have been reported to contain large amounts of vitamin B, vitamin C, and flavonoids. They exhibit various physiological activities such as antitumor and anti-inflammatory effects. However, the hepatoprotective effects of C. tricuspidata extracts against oxidative stress-mediated liver injury have not yet been investigated. We thus examined whether C. tricuspidata leaf extracts (CTEs) protect against oxidative stress-mediated liver injury in vitro and in vivo and elucidated the underlying mechanism. The cytoprotective effects of CTE through the NF-E2-related factor 2 (Nrf2)/antioxidant response element (ARE) activation were presented and measured by biochemical analysis in HepG2 cells. To assess the protective effects of CTE in vivo, mice were administered with CTE (250 and 500 mg/kg; 5 days; p.o.) before a single dose of acetaminophen (APAP) (300 mg/kg; 24 h; i.p.). CTE increased ARE luciferase activity when compared with extracts of other parts of C. tricuspidata. CTE upregulated nuclear translocation of Nrf2 and its target gene expression. In addition, CTE inhibited the generation of reactive oxygen species (ROS) and cell death induced by arachidonic acid (AA) and iron (Fe) treatment in primary hepatocytes or HepG2 cells. The cytoprotective effects of CTE against oxidative stress might be due to kaempferol, the major flavonoid present in CTE. Kaempferol pretreatment blocked AA+Fe-induced ROS production and reversed glutathione depletion, which in turn led to decreased cell death. Furthermore, the protective effects of CTE against liver injury induced by excess APAP in mice or primary hepatocytes were observed. CTE could be a promising therapeutic candidate against oxidative stress-induced liver injury.

Apoptotic effects of hsian-tsao ( Mesona procumbens Hemsley) on hepatic stellate cells mediated by reactive oxygen species and ERK, JNK, and caspase-3 pathways. Food Sci Nutr 2019; 7:1891-1898. [PMID: 31139404 PMCID: PMC6526671 DOI: 10.1002/fsn3.1046] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2019] [Revised: 03/31/2019] [Accepted: 04/07/2019] [Indexed: 12/20/2022] Open
Abstract
The activation of hepatic stellate cells (HSCs) is an important step in the progress of liver fibrosis. Fibrosis can be impeded by HSC reversion to a quiescent state or HSC clearance through apoptosis. To investigate the apoptotic effects of hsian-tsao (Mesona procumbens Hemsl) on human HSCs, the expression levels of cleaved caspase-3, p38, and c-Jun N-terminal kinase (JNK) were assessed using Western blotting, and the caspase-3 activity was measured using caspase-3/CPP32 colorimetric assay kit. Hsian-tsao extract (HTE) increased the activity of caspase-3 and the level of activated caspase-3, indicating the activation of apoptosis. The intracellular reactive oxygen species (ROS) level increased in a dose-dependent manner. This increase was prevented by an antioxidant, suggesting that HTE induces ROS accumulation. In addition, we found that HTE induced the phosphorylation of the mitogen-activated protein kinases JNK and p38. These collective data indicate that HTE induces apoptosis via ROS production through the p38, JNK, and caspase-3-dependent pathways. HTE may decrease HSC activation in liver fibrosis and may have a therapeutic potential.

Biomed Pharmacother 2019; 115:108788. [PMID: 31035010 DOI: 10.1016/j.biopha.2019.108788] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2018] [Revised: 02/23/2019] [Accepted: 03/13/2019] [Indexed: 01/15/2023] Open
Abstract
This study investigated the antifibrotic effect of Prosopis juliflora leaves crude methanolic extract (PJEL) against thioacetamide (TAA)-induced liver fibrosis. The phytochemical analysis of PJEL was performed via HPLC/MS in association with evaluating its free radical scavenging and cytotoxic activities. The antifibrotic activity of PJEL was assessed by dividing Wistar rats into 8 groups: normal control, PJEL1-administered rats (2 mg/ Kg b.w.), PJEL2-administered rats (4 mg/ Kg b.w.), PJEL3-administered rats (8 mg/Kg b.w.), TAA-induced hepatic fibrosis, TTA + PJEL1, TAA + PJEL2, and TAA + PJEL3. Results indicated that PJEL crude methanolic extract is rich in polyphenolic compounds and alkaloids. PJEL exerted free radical scavenging activity with IC50 of 123.5 μg/mL and cytotoxic activity against a well-differentiated hepatocellular cell line (IC50 = 11.1 μg/mL). PJEL at a dose of 4 mg/Kg b.w. ameliorated serum ALT activity and improved serum albumin level and hepatic hydroxyproline content in association with a reduction in the fibrosis stage. PJEL elevated hepatic tumor necrosis factor-α and interleukin-6 contents with less necrosis grade. PJEL post-therapy ameliorated the relative expression of Bcl-2, Col1A1, Mmp-9, and Mmp-2 genes in liver. CONCLUSION: PJEL possesses a good therapeutic activity against TAA-induced liver fibrosis via enhancing extracellular matrix removal and stimulating hepatic regeneration to decrease hepatic necrosis.

Abstract
Treatment of liver fibrosis is very limited as there is currently no effective anti-fibrotic therapy. Spirulina platensis (SP) is a blue-green alga that is widely supplemented in healthy foods. The objective of this study was to determine whether SP supplementation can prevent obesity-induced liver fibrosis in vivo. Male C57BL/6J mice were randomly assigned to a low-fat or a high-fat (HF)/high-sucrose/high-cholesterol diet or an HF diet supplemented with 2·5 % SP (w/w) (HF/SP) for 16 or 20 weeks. There were no significant differences in body weight, activity, energy expenditure, serum lipids or glucose tolerance between mice on HF and HF/SP diets. However, plasma alanine aminotransferase level was significantly reduced by SP at 16 weeks. Expression of fibrotic markers and trichrome stains showed no differences between HF and HF/SP. Splenocytes isolated from HF/SP fed mice had lower inflammatory gene expression and cytokine secretion compared with splenocytes from HF-fed mice. SP supplementation did not attenuate HF-induced liver fibrosis. However, the expression and secretion of inflammatory genes in splenocytes were significantly reduced by SP supplementation, demonstrating the anti-inflammatory effects of SP in vivo. Although SP did not show appreciable effect on the prevention of liver fibrosis in this mouse model, it may be beneficial for other inflammatory conditions.

Abstract
Alcoholic fatty liver disease (AFLD) and non-alcoholic fatty liver disease (NAFLD) are two pathological conditions that are spreading worldwide. Both conditions are remarkably similar with regard to the pathophysiological mechanism and progression despite different causes. Oxidative stressinduced mitochondrial dysfunction through post-translational protein modifications and/or mitochondrial DNA damage has been a major risk factor in both AFLD and NAFLD development and progression. Cytochrome P450-2E1 (CYP2E1), a known important inducer of oxidative radicals in the cells, has been reported to remarkably increase in both AFLD and NAFLD. Interestingly, CYP2E1 isoforms expressed in both endoplasmic reticulum (ER) and mitochondria, likely lead to the deleterious consequences in response to alcohol or in conditions of NAFLD after exposure to high fat diet (HFD) and in obesity and diabetes. Whether CYP2E1 in both ER and mitochondria work simultaneously or sequentially in various conditions and whether mitochondrial CYP2E1 may exert more pronounced effects on mitochondrial dysfunction in AFLD and NAFLD are unclear. The aims of this review are to briefly describe the role of CYP2E1 and resultant oxidative stress in promoting mitochondrial dysfunction and the development or progression of AFLD and NAFLD, to shed a light on the function of the mitochondrial CYP2E1 as compared with the ER-associated CYP2E1. We finally discuss translational research opportunities related to this field.

Abstract
Hepatic fibrosis, characterized by persistent deposition of extracellular matrix (ECM) proteins, occurs in most types of chronic liver disease. The prevention of liver damage using extract of Dendropanax morbifera has been widely studied, but its molecular mechanism on the therapeutic efficacy of hepatic fibrosis is unclear. The aim of this study was to assess whether aquatic extract (DM) of D. morbifera ameliorates thioacetamide (TAA)-induced hepatic fibrosis. Hepatic fibrosis was induced by an intraperitoneal (i.p.) injection (150 mg/kg, twice per week) of TAA for 6 weeks. DM (50 mg/kg/day) or silymarin (50 mg/kg/day) was administered daily for 6 weeks. DM markedly reduced serum AST, ALT, ALP, and r-GTP in TAA-treated rats. DM significantly ameliorated the total glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT) activity in TAA-treated rats. In particular, DM significantly reduced expression of α-SMA, type I collagen, vimentin, TGF-β1 and p-Smad2/3 in hepatic fibrosis rats. The protective effects of DM on progression of hepatic fibrosis were clearly shown by detecting 4-hydroxyproline concentration and histopathological examination in the liver. Therefore, our data suggest that DM dramatically prevented hepatic fibrosis by inhibiting oxidative stress and the TGF-β1/Smads signaling pathways.

Abstract
Background Considerable morbidity, mortality, and economic loss result from schistosomiasis infection. Deposition of Schistosoma eggs in the hepatic portal vein is considered as the main causative agent for the development of liver fibrosis and subsequent liver cirrhosis. Probiotics are exogenous and beneficial microorganisms to living hosts against the harmful effect of many parasites. Strong evidence suggests the importance of probiotics in the control strategy of helminth. The ultimate goal of this study is to evaluate the protective effect of probiotics and yogurt on Schistosoma mansoni-induced oxidative stress and hepatic fibrosis in mice. Methods Mice were infected by tail immersion of schistosomal cercariae followed by an oral treatment with either probiotics or yogurt for one week before infection and immediately post-infection. Mice were scarified on day 56 following infection with S. mansoni and liver sample were obtained. Results We showed that oral administration of probiotics or yogurt revealed a significant reduction in worm number, egg load, and granuloma size in liver tissue, which is mainly assigned to the decreased expression level of matrix metalloproteinases 9 (MMP-9) in liver tissue. A significant reduction in the oxidative stress markers-induced by S. mansoni infection including lipid peroxidation and nitrite/nitrate was also detected. The level of some antioxidant enzymes (superoxide dismutase, catalase, glutathione peroxidase and glutathione reductase) and reduced glutathione was greatly enhanced. Furthermore, treatment with probiotics or yogurt inhibited apoptosis in hepatic tissue, which is mainly assigned to the decreased expression level of caspases-3 in liver tissue. Conclusion Our findings represent the promising anti-schistosomal activities of probiotics and yogurt.

Abstract
Introduction: This study was carried out to evaluate the antioxidant potential of crude extract of Solanum nigrum leaves and its active constituents as treatment against restraint stress in rat’s liver. Methods: For this purpose, male albino Wistar rats were treated with crude extract of leaves and its alkaloid and flavonoid fractions both before and after 6 h of acute restraint stress. Prooxidant status of rat liver was assessed by determining the levels of thiobarbituric acid reactive substances, reduced glutathione, alkaline phosphatase, alanine transaminase, aspartate aminotransferase, and the activities of antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), and glutathione S-transferase (GST). Results: Six hours of restraint stress generated oxidative stress in rat’s liver resulted in a significant rise in the level of the aforementioned liver enzymes. On the other hand, SOD, CAT, and GST enzymatic activities showed a significant decline in their level. The administration of crude leaves extract, both before and after stress exposure, significantly prevented the rise in the level of liver enzymes and reverted the activities of studied biochemical parameters toward their normal control values. However, the reversion was found to be more prominent in after-stress group. Conclusion: The aforementioned results highlight the significant antioxidant potential of S. nigrum extracts. On the basis of our study, we suggest the possible use of S. nigrum leaves extract as a nutritional supplement for combating oxidative stress induced damage.

Abstract
Ataxia telangiectasia (A-T) is a devastating multi-system disorder characterized by progressive cerebellar ataxia, immunodeficiency, genetic instability, premature aging and growth retardation. Due to better care the patients get older than in the past and new disease entities like disturbed glucose tolerance and liver disease emerge. The objective of the present investigation is to determine the evolution of liver disease and its relation to age and neurological deterioration. The study included 67 patients aged 1 to 38 years with classical A-T. At least two measurements of liver enzymes were performed within a minimum interval of 6 months in 56 patients. The median follow-up period was 4 years (1-16 years). A total of 316 liver enzyme measurements were performed. For analysis, patients were divided into two age groups (Group 1: <12 years; group 2: ≥12 years). In addition, ultrasound of the liver and Klockgether Ataxia Score (KAS) were analyzed. We found significantly higher levels of alpha-fetoprotein (AFP) (226,8 ± 20.87 ng/ml vs. 565,1 ± 24.3 ng/ml, p < 0.0001), and liver enzymes like ALT (23.52 ± 0.77 IU/L vs. 87.83 ± 5.31 IU/L, p < 0.0001) in patients in group 2. In addition, we could show a significant correlation between age and AFP, GGT, and KAS. Ultrasound revealed hepatic steatosis in 11/19 (57.9%) patients in group 2. One female patient aged 37 years died due to a hepato-cellular carcinoma (HCC). Liver disease is present in the majority of older A-T patients. Structural changes, non-alcoholic fatty liver disease and fibrosis are frequent findings. Progress of liver disease is concomitant to neurological deterioration.

Abstract
Aim. To study the features of lipid peroxidation of biological membranes and accumulation of toxic metabolites in the body of patients with psoriasis, depending on the presence of concomitant chronic viral hepatitis C.Materials and methods. In the survey, participated 56 patients with a vulgar form of psoriasis who received in-patient treatment at the Nalchik skin clinic in 2016–2017, divided into 2 groups, depending on the presence of concomitant chronic viral hepatitis C. In patients, the content of malonic dialdehyde in blood was determined as an indicator of the state of the prooxidant system, ceruloplasmin and erythrocyte catalase, as indicators of antioxidant protection, and also for the evaluation of the Intoxication Syndrome; the level of substances of low and medium molecular mass and oligopeptides in the biological environments of the organism in different periods of the disease.Results. It was found that the presence of concomitant chronic viral hepatitis C in patients with psoriasis was characterized by a more pronounced increase in the concentration of lipid peroxidation products than in the group of patients with hepatitis without psoriasis, accompanied by a decrease in the activity of antioxidant enzymes in the blood plasma and an increase in the activity of catalase in erythrocytes. Simultaneously, the presence of chronic hepatitis C led to a significantly higher content in the body fluids of patients with low and medium molecular weight substances and oligopeptides.

PHARMACEUTICAL BIOLOGY 2018; 56:632-642. [PMID: 31070527 PMCID: PMC6282452 DOI: 10.1080/13880209.2018.1529801] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/12/2018] [Revised: 09/13/2018] [Accepted: 09/19/2018] [Indexed: 06/09/2023]
Abstract
CONTEXT Allium senescens Linn. (Liliaceae) (ASL) has been traditionally used in Korea and other Asian countries for improving digestive and liver functions. OBJECTIVE The anti-hepatofibrosis effect of ASL ethanol extract in cellular and experimental fibrosis rat model was investigated. MATERIALS AND METHODS In vitro cell viability, cell cycle and apoptosis in hepatic stellate cells (HSCs) were studied using MTT assay, flow cytometry and Annexin V-FITC/PI staining. Thioacetamide (TAA; 200 mg/kg, i.p.)-induced liver fibrosis model using Sprague Dawley rats (n = 10) was developed in vivo by injecting TAA twice per week for 13 weeks. ASL (25 and 100 mg/kg) and silymarin (50 mg/kg) were administered through oral gavage 2 times per week from 7th to 13th week. Specific fibrotic-related biomarkers such as aspartate transaminase (AST), alanine transaminase (ALT), glutathione and hydroxyproline levels in serum were analyzed by spectrophotometer using commercial kits. Morphological, histopathological and fibrotic-related gene expression such as TGF-β, Col1α1 and α-SMA in liver tissues was estimated by hematoxylin and eosin staining, Picrosirius red stain and quantitative real-time polymerase chain reaction, respectively. RESULTS ASL (0.1 mg/mL) and silymarin (0.05 mg/mL) treatment induced apoptosis (4.06% and 8.67%) in activated HSC-T6 cells, compared with control group (3.7%). The altered morphology in activated primary HSCs was also restored by ASL (0.1 mg/mL) treatment. Further, ASL (100 and 25 mg/kg) ameliorated the TAA-induced altered fibrotic-related biomarkers, histopathological changes and fibrotic-related gene expression significantly (p < 0.05 ∼ p < 0.001). CONCLUSIONS ASL can potentially be developed as a therapeutic agent in the treatment of hepatic fibrosis.

Abstract
A decrease in skeletal muscle mass and motor function occurs in diabetic patients. In type 1 diabetic patients, in particular, fast-type fiber-dominated muscle atrophy occurs due to increased oxidative stress and inflammation. Juzentaihoto is a herbal medicine that has been found to be effective in reducing oxidative stress. In this study, juzentaihoto hot water extract (JTT) was administered prophylactically to mice with diabetic oxidative stress, which was induced by an injection of streptozotocin, and the effects on skeletal muscle mass, motor function, and antioxidant activity were evaluated. In mice that were administered JTT, skeletal muscle atrophy and loss of motor function were suppressed. Additionally, the administration of JTT increased the mRNA expression level of Sirt1 and the activity of superoxide dismutase in the gastrocnemius. In addition to skeletal muscle atrophy, atrophy of the liver, spleen and thymus gland, and kidney hypertrophy were also suppressed. Furthermore, in order to evaluate the antioxidant activity of 10 constituent crude drugs that comprise juzentaihoto, Sirt1 transcriptional activity in C2C12 cells was evaluated. The Sirt1 transcriptional activity was increased by Cinnamomi Cortex, Astragali Radix, and Glycyrrhizae Radix extracts. These three constituent crude drugs play an important function in the antioxidant action of juzentaihoto, suggesting that juzentaihoto can prevent muscle atrophy by decreasing oxidative stress.

Abstract
Purpose Currently, there are no effective therapies for liver fibrosis; hence, the development of anti-liver fibrosis agents is urgently needed. Here, we attempted to investigate the therapeutic effect and mechanism of asiatic acid (AA) on liver fibrosis, mainly focusing on the impact of AA on nuclear erythroid 2-related factor 2/antioxidant response element (Nrf2/ARE), nuclear factor-kappa B (NF-κB)/IκBα, and JAK1/signal transducer and activator of transcription 3 (STAT3) signaling pathways. Methods Rats were induced liver fibrosis by carbon tetrachloride (CCl4) for 6 weeks and concomitantly treated with AA (5 and 15 mg/kg) or vehicle by daily gavage. After AA treatment, the morphology of liver tissue was analyzed by H&E and Masson’s trichrome staining, and serum biochemical indicators were also assayed. Thereafter, the protein levels of Nrf2, HO-1, NQO-1, GCLC, NF-κB, IκBα, JAK1, p-JAK1, STAT3, and p-STAT3 were determined by Western blotting. Results Our results showed that AA treatment dramatically ameliorated CCl4-induced oxidative stress, inflammation, and fibrosis in rats. The expression of nuclear Nrf2 was increased after AA treatment, whereas cytoplasm Nrf2 levels were decreased. The protein expression of Nrf2 target proteins including HO-1, NQO-1, and GCLC was significantly increased by AA treatment. Furthermore, AA treatment decreased the levels of nuclear NF-κB to inhibit NF-κB/IκBα signaling pathway. In addition, we also found that AA treatment regulated JAK1/STAT3 signaling by decreasing the phosphorylation levels of JAK1 and STAT3. Conclusion These results demonstrate that AA ameliorates CCl4-induced liver fibrosis in rats by regulating Nrf2/ARE, NF-κB/IκBα, and JAK1/STAT3 signaling pathways, which suggests that AA might be a new antifibrosis agent that improves liver fibrosis.

Identification of a Shared Cytochrome p4502E1 Epitope Found in Anesthetic Drug-Induced and Viral Hepatitis. mSphere 2018; 3:3/5/e00453-18.

Abstract
Drug-induced hepatitis is the leading reason that an approved drug is removed from the commercial market. Halogenated anesthetics can induce hepatitis in susceptible persons, and cytochrome p4502E1 (CYP2E1) enzymes responsible for their metabolism induce antibodies in addition to hepatitis. CYP2E1 antibodies detected in anesthetic hepatitis patients have been detected in patients with viral hepatitis, suggesting that these different forms of hepatitis could develop immune reactions to a common segment or epitope of CYP2E1. We have found a common MHC-restricted CYP2E1 epitope in anesthetic and viral hepatitis that is a dominant epitope in anesthetic hepatitis and is significantly associated with fibrosis in patients with viral hepatitis. Along with conformational epitopes, our identification of MHC-restricted CYP2E1 epitopes can be used to develop specific diagnostic tests for drug-induced or viral hepatitis or associated fibrosis or to predict individuals at risk for developing these diseases or their sequelae. Cytochrome p4502E1 (CYP2E1) autoantibodies are biomarkers for drug-induced hepatitis and chronic hepatitis C. However, major histocompatibility-restricted CYP2E1 epitopes associated with these diseases have not been identified. We hypothesized that CYP2E1 epitopes associated with different types of hepatitis may be shared and may impact immune responses and metabolism. SYFPEITHI epitope prediction identified CYP2E1 candidate epitopes that would be recognized by MHC II haplotypes. Candidate epitopes were tested for induction of hepatitis and CYP2E1 autoantibodies in mice and recognition by sera from patients with anesthetic drug-induced and viral hepatitis. Human liver cells treated with epitope hybridoma serum were analyzed for mitochondrial stress. CYP2E1 activity was measured in human microsomes similarly treated. Epitope antibodies in viral hepatitis sera were analyzed using linear regression to uncover associations with liver pathology. A P value of <0.05 was considered significant. One epitope (Gly113-Leu135) induced hepatitis and CYP2E1 autoantibodies in mice after modification of Lys123 (P < 0.05). Gly113-Leu135 antiserum recognized mitochondria and endoplasmic reticula (P < 0.05), upregulated HSP27 (P < 0.01) and mitochondrial oxidative stress via complex 1 inhibition (P < 0.001), and inhibited CYP2E1 activity. Gly113-Leu135 IgG4 detected in viral hepatitis sera was associated with severe hepatic fibrosis (P = 0.0142). We found a novel CYP2E1 epitope that was detected in anesthetic and viral hepatitis and that triggered hepatitis in mice. Our findings may improve understanding of hepatic immune responses triggered by metabolism or viruses. IMPORTANCE Drug-induced hepatitis is the leading reason that an approved drug is removed from the commercial market. Halogenated anesthetics can induce hepatitis in susceptible persons, and cytochrome p4502E1 (CYP2E1) enzymes responsible for their metabolism induce antibodies in addition to hepatitis.

Abstract
Schistosomiasis is a widespread parasitic infection that affects humans, as well as wild and domestic animals. It ranks second after malaria, with a significant health and socio-economic impact in the developing countries. The objective of this study was to assess the anti-schistosomal impact of Ziziphus spina-christi leaf extract (ZLE) on Schistosoma mansoni-induced liver fibrosis in CD-1 Swiss male albino mice. S. mansoni infection was achieved by dipping of mouse tails in schistosomal cercariae. ZLE treatment was initiated at 46 days post-infection by administering a dose of the extract on a daily basis for 10 consecutive days. S. mansoni infection resulted in liver granuloma and fibrosis, with a drastic elevation in liver function factors, nitric oxide, and lipid peroxidation, which were associated with a reduction in glutathione content and substantial inhibition of antioxidant enzyme activities compared to those of the control. Induction of hepatic granuloma, oxidative stress, and fibrosis in the liver was controlled by ZLE administration, which also produced inhibition of matrix metalloproteinase-9, alpha-smooth muscle actin, transforming growth factor-β, and tissue inhibitors of metalloproteinases expressions. In addition, the S. mansoni-infected group exhibited an increase in Bax and caspase-3 levels and a decrease in Bcl-2 level. However, treatment with ZLE mainly mitigated apoptosis in the liver. Thus, the findings of this study revealed that Ziziphus spina-christi had anti-apoptotic, anti-fibrotic, antioxidant, and protective effects on S. mansoni-induced liver wounds. The benefits of Ziziphus spina-christi extract on S. mansoni were partly partially mediated by enhancing anti-fibrinogenic and nuclear factor erythroid 2–related factor 2 (Nrf2) pathways.

Lipotoxicity induces hepatic protein inclusions through TANK binding kinase 1-mediated p62/sequestosome 1 phosphorylation. Hepatology 2018; 68:1331-1346. [PMID: 29251796 PMCID: PMC6005718 DOI: 10.1002/hep.29742] [Citation(s) in RCA: 66] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2017] [Revised: 12/07/2017] [Accepted: 12/12/2017] [Indexed: 12/30/2022]
Abstract
UNLABELLED Obesity commonly leads to hepatic steatosis, which often provokes lipotoxic injuries to hepatocytes that cause nonalcoholic steatohepatitis (NASH). NASH, in turn, is associated with the accumulation of insoluble protein aggregates that are composed of ubiquitinated proteins and ubiquitin adaptor p62/sequestosome 1 (SQSTM1). Formation of p62 inclusions in hepatocytes is the critical marker that distinguishes simple fatty liver from NASH and predicts a poor prognostic outcome for subsequent liver carcinogenesis. However, the molecular mechanism by which lipotoxicity induces protein aggregation is currently unknown. Here, we show that, upon saturated fatty acid-induced lipotoxicity, TANK binding kinase 1 (TBK1) is activated and phosphorylates p62. TBK1-mediated p62 phosphorylation is important for lipotoxicity-induced aggregation of ubiquitinated proteins and formation of large protein inclusions in hepatocytes. In addition, cyclic GMP-AMP synthase (cGAS) and stimulator of interferon genes (STING), upstream regulators of TBK1, are involved in lipotoxic activation of TBK1 and subsequent p62 phosphorylation in hepatocytes. Furthermore, TBK1 inhibition prevented formation of ubiquitin-p62 aggregates not only in cultured hepatocytes, but also in mouse models of obesity and NASH. CONCLUSION These results suggest that lipotoxic activation of TBK1 and subsequent p62 phosphorylation are critical steps in the NASH pathology of protein inclusion accumulation in hepatocytes. This mechanism can provide an explanation for how hypernutrition and obesity promote the development of severe liver pathologies, such as steatohepatitis and liver cancer, by facilitating the formation of p62 inclusions.
