Huang BH, Guo ZW, Lv BH, Zhao X, Li YB, Lv WL. A role for curcumin in preventing liver fibrosis in animals: a systematic review and meta-analysis. Front Pharmacol 2024; 15:1396834. [PMID: 38855740 PMCID: PMC11157132 DOI: 10.3389/fphar.2024.1396834] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Accepted: 04/30/2024] [Indexed: 06/11/2024] Open
Abstract
Objective This meta-analysis aimed to determine the efficacy of curcumin in preventing liver fibrosis in animal models. Methods A systematic search was conducted on studies published from establishment to November 2023 in PubMed, Web of Science, Embase, Cochrane Library, and other databases. The methodological quality was assessed using Sycle's RoB tool. An analysis of sensitivity and subgroups were performed when high heterogeneity was observed. A funnel plot was used to assess publication bias. Results This meta-analysis included 24 studies involving 440 animals with methodological quality scores ranging from 4 to 6. The results demonstrated that curcumin treatment significantly improved Aspartate aminotransferase (AST) [standard mean difference (SMD) = -3.90, 95% confidence interval (CI) (-4.96, -2.83), p < 0.01, I2 = 85.9%], Alanine aminotransferase (ALT)[SMD = - 4.40, 95% CI (-5.40, -3.40), p < 0.01, I2 = 81.2%]. Sensitivity analysis of AST and ALT confirmed the stability and reliability of the results obtained. However, the funnel plot exhibited asymmetry. Subgroup analysis based on species and animal models revealed statistically significant differences among subgroups. Furthermore, curcumin therapy improved fibrosis degree, oxidative stress level, inflammation level, and liver synthesis function in animal models of liver fibrosis. Conclusion Curcumin intervention not only mitigates liver fibrosis but also enhances liver function, while concurrently modulating inflammatory responses and antioxidant capacity in animal models. This result provided a strong basis for further large-scale animal studies as well as clinical trials in humans in the future.

[PMID: 38781262 PMCID: PMC11115266 DOI: 10.1371/journal.pone.0304176] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2024] [Accepted: 05/03/2024] [Indexed: 05/25/2024] Open
Abstract
OBJECTIVE This study aimed to evaluate the intervention effect of curcumin on hepatic fibrosis in rodent models through systematic review and meta-analysis, in order to provide meaningful guidance for clinical practice. METHODS A systematic retrieval of relevant studies on curcumin intervention in rats or mice hepatic fibrosis models was conducted, and the data were extracted. The outcome indicators included liver cell structure and function related indicators, such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), albumin (ALB), ratio of albumin to globulin (A/G), total bilirubin (TBIL), bax protein, bcl-2 protein and index of liver, as well as the relevant indicators for evaluating the degree of hepatic fibrosis, such as hyaluronic acid (HA), laminin (LN), type I collagen (Collagen I), type III collagen (Collagen III), type III procollagen (PCIII), type III procollagen amino terminal peptide (PIIINP), type IV collagen (IV-C), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), α-Smooth muscle actin (α-SMA), hydroxyproline (HYP), platelet derived factor-BB (PDGF-BB), connective tissue growth factor (CTGF) and transforming growth factor-β1 (TGF-β1), and oxidative stress-related indicators, such as superoxide dismutase (SOD), malondialdehyde (MDA) and glutathione peroxidase (GSH-Px). These results were then analyzed by meta-analysis. Studies were evaluated for methodological quality using the syrcle's bias risk tool. RESULTS A total of 59 studies were included in the meta-analysis, and the results showed that curcumin can reduce the levels of ALT, AST, ALP, TBIL, bax protein, and index of liver in hepatic fibrosis models. It can also reduce HA, LN, Collagen I, Collagen III, PCIII, PIIINP, IV-C, TNF-α, α-SMA, HYP, PDGF-BB, CTGF, TGF-β1 and MDA, and increase the levels of ALB, A/G, SOD, and GSH-Px in the hepatic fibrosis models. However, the effects of curcumin on bcl-2 protein, IL-6 in hepatic fibrosis models and index of liver in mice were not statistically significant. CONCLUSION The analysis results indicate that curcumin can reduce liver cell apoptosis by maintaining the stability of liver cell membrane, inhibit the activation and proliferation of hepatic stellate cells by reducing inflammatory response, and alleviate tissue peroxidation damage by clearing oxygen free radicals.

Abstract
Tumor-derived exosome (TDE)-mediated premetastatic niche (PMN) formation is a potential mechanism underlying the organotropic metastasis of primary tumors. Traditional Chinese medicine (TCM) has shown considerable success in preventing and treating tumor metastasis. However, the underlying mechanisms remain elusive. In this review, we discussed PMN formation from the perspectives of TDE biogenesis, cargo sorting, and TDE recipient cell alterations, which are critical for metastatic outgrowth. We also reviewed the metastasis-preventive effects of TCM, which act by targeting the physicochemical materials and functional mediators of TDE biogenesis, regulating the cargo sorting machinery and secretory molecules in TDEs, and targeting the TDE-recipient cells involved in PMN formation.

Abstract
The liver is a vital organ that plays a crucial role in the physiological operation of the human body. The liver controls the body's detoxification processes as well as the storage and breakdown of red blood cells, plasma protein and hormone production, and red blood cell destruction; therefore, it is vulnerable to their harmful effects, making it more prone to illness. The most frequent complications of chronic liver conditions include cirrhosis, fatty liver, liver fibrosis, hepatitis, and illnesses brought on by alcohol and drugs. Hepatic fibrosis involves the activation of hepatic stellate cells to cause persistent liver damage through the accumulation of cytosolic matrix proteins. The purpose of this review is to educate a concise discussion of the epidemiology of chronic liver disease, the pathogenesis and pathophysiology of liver fibrosis, the symptoms of liver fibrosis progression and regression, the clinical evaluation of liver fibrosis and the research into nanotechnology-based synthetic and herbal treatments for the liver fibrosis is summarized in this article. The herbal remedies summarized in this review article include epigallocathechin-3-gallate, silymarin, oxymatrine, curcumin, tetrandrine, glycyrrhetinic acid, salvianolic acid, plumbagin, Scutellaria baicalnsis Georgi, astragalosides, hawthorn extract, and andrographolides.

Abstract
Invasion and metastasis are the main reasons for the high mortality of liver cancer, which involve the interaction of tumor stromal cells and malignant cells. Cancer-associated fibroblasts (CAFs) are one of the major constituents of tumor stromal cells affecting tumor growth, invasion, and metastasis. The heterogeneous properties and sources of CAFs make both tumor-supporting and tumor-suppression effects possible. The mechanisms for CAFs in supporting hepatocellular carcinoma (HCC) progression can be categorized into upregulated aggressiveness and stemness, transformed metabolism toward glycolysis and glutamine reductive carboxylation, polarized tumor immunity toward immune escape of HCC cells, and increased angiogenesis. The tumor-suppressive effect of fibroblasts highlights the functional heterogenicity of CAF populations and provides new insights into tumor–stromal interplay mechanisms. In this review, we introduced several key inflammatory signaling pathways in the transformation of CAFs from normal stromal cells and the heterogeneous biofunctions of activated CAFs. In view of the pleiotropic regulation properties of traditional Chinese medicine (TCM) and heterogeneous effects of CAFs, we also introduced the application and values of TCM in the treatment of HCC through targeting CAFs.

Abstract
This study investigates the hepatoprotective effect of bone marrow mononuclear cells (BM-MNCs) transplantation, N-acetylcysteine (NAC) and α-lipoic acid (ALA). Rats were administrated carbon tetrachloride (CCl4) (1 mg/kg, i.p.) twice/week for 8 weeks for the induction of hepatotoxicity. 7 groups of rats were used as follows: Normal control, CCl4, CCl4 co-administered with BM-MNCs (1 × 106 in 0.1 ml PBS, i.v.), or NAC (300 mg/kg, p.o) or ALA (100 mg/kg, p.o) single or combination. Liver function was tested by measuring serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and albumin as well as interleukin-6 (IL-6), interleukin-10 (IL-10), tumor necrosis factor-α (TNF-α), malondialdehyde (MDA), total antioxidant capacity (TAC), glutathione peroxidase (Gpx), superoxide dismutase (SOD) and catalase (CAT) activities in liver homogenates. Besides that, estimation of DNA damage was performed. In addition to Micronucleus test and histopathological investigation. CCl4 treated rats showed elevation in ALT, AST, TNF-α, IL-6 and MDA accompanied by reduction in ALB, IL-10, SOD, CAT, GPx and TAC and increased the number of DNA breaks in liver tissue, showed many micronucleated polychromatic erythrocytes (MnPCEs) in bone marrow. NAC, ALA, BM-MNCs and their combination caused a reduction of ALT, AST, while, increase albumin, CAT, TAC, GPx, SOD as compared to CCl4 treated groups. Also decrease in MDA, IL-6 and TNF-α concurrently with an increase in IL-10. Moreover, BM-MNCs, NAC, ALA, and their combination decreased DNA tail %, and the count of MnPCEs. BM-MNCs combination with NAC or ALA exerted significant antioxidant, anti-inflammatory and anti-cytogenetical aberrations effect compared to each of them alone.HighlightsCCl4 elevated ALT, AST, TNF-α, IL-6 and MDACCl4 reduced ALB, IL-10, SOD, CAT, GPx and TACCCl4 increased the number of DNA breaks in liverNAC, ALA and BM-MNCs reduced ALT, AST, while, increase albumin, CAT, TAC, GPx, SODNAC, ALA and BM-MNCs decreased in MDA, IL-6 and TNF-α and increased IL-10 [Figure: see text].

Abstract
Alpha-lipoic acid (α-LA), a well-known antioxidant, was proved to active ALDH2 in nitrate tolerance and diabetic animal model. However, the therapeutic advantage of α-LA for heart failure and related signaling pathway have not been explored. This study was designed to examine the role of α-LA–ALDH2 in heart failure injury and mitochondrial damage. ALDH2 knockout (ALDH2−/−) mice and primary neonatal rat cardiomyocytes (NRCMs) were subjected to assessment of myocardial function and mitochondrial autophagy. Our data demonstrated α-LA significantly reduced the degree of TAC-induced LV hypertrophy and dysfunction in wild-type mice, not in ALDH2−/− mice. In molecular level, α-LA significantly restored ALDH2 activity and expression as well as increased the expression of a novel mitophagy receptor protein FUNDC1 in wild-type TAC mice. Besides, we confirmed that ALDH2 which was activated by α-LA governed the activation of Nrf1–FUNDC1 cascade. Our data suggest that α-LA played a positive role in protecting the heart against adverse effects of chronic pressure overload.

Abstract
Lipoic acid (LA) has been shown to possess protective effects against liver fibrosis mainly by induction of apoptosis of activated hepatic stellate cells, but the mechanism of LA activity in liver fibrosis has yet to be completely explained. LA occurs naturally in mitochondria as a coenzyme. In this study, we used mice with schistosomiasis-induced liver fibrosis and mouse hepatocarcinoma cell line 1C1C7 as models to investigate the mitochondrial mechanism of LA treatment for liver fibrosis. Western blot, real-time PCR and oxygen consumption rate (OCR) test were used. In the livers of mice with liver fibrosis, the mRNA levels of LA synthetic pathway enzymes, including MCAT, OXSM, MECR, and LIAS, were significantly reduced. Livers of mice with liver fibrosis showed degenerative signs, such as mitochondrial edema, a reduced mitochondrial crest and matrix density, or vacuolation; the activities of mitochondrial complexes I, II, IV, and V were also decreased in these livers. The expression of phosphorylation Drp1 (p-Drp1) was decreased in the livers of mice with liver fibrosis, indicating increased mitochondrial fission activity, whereas OPA1 and MFN1 expression was reduced, denoting decreased activity of mitochondrial fusion. To understand the mitochondrial mechanism of LA treatment for liver fibrosis, p-Drp1, OPA1, and MFN1 expression were detected at the protein level in mouse hepatocarcinoma cell line 1C1C7 stimulated by LA. OPA1 and MFN1 were not significantly altered, but p-Drp1 was significantly increased. The results suggest that LA may alleviate liver fibrosis through upregulating p-Drp1. This study provides a new insight into the mechanism of the protective effect of LA against schistosomiasis-induced liver fibrosis, which demonstrates that LA is required for the maintenance of mitochondrial function by upregulating p-Drp1 expression to inhibit mitochondrial fission.

Abstract
Liver fibrosis is a progressive liver damage condition that is worth studying widely. It is important to target and alleviate the disease at an early stage before turning into later cirrhosis or liver cancer. There are currently no direct medicines targeting the attenuation or reversal of liver fibrosis, and so there is an urgent need to look into this area. Traditional Chinese Medicine has a long history in using herbal medicines to treat liver diseases including fibrosis. It is time to integrate the ancient wisdom with modern science and technology to look for the best solution to the disease. In this review, the principal concept of the pathology of liver fibrosis will be described, and then some of the single compounds isolated from herbal medicines, including salvianolic acids, oxymatrine, curcumin, tetrandrine, etc. will be discussed from their effects to the molecular mechanism behind. Molecular targets of the compounds are analyzed by network pharmacology approach, and TGFβ/SMAD was identified as the most common pathway. This review serves to summarize the current findings of herbal medicines combining with modern medicines in the area of fibrosis. It hopefully provides insights in further pharmaceutical research directions.

Abstract
BACKGROUND/AIM The hepatoprotective role of various molecules in drug-induced hepatotoxicity arouses great interest. We investigated the effect of liposomal curcumin (LCC) on experimental acetaminophen (APAP)-induced hepatotoxicity. MATERIALS AND METHODS Rats were randomly allocated into 5 groups, and the effect of two LCC concentrations was studied: group 1 - 1 ml intraperitoneal (i.p.) saline, group 2 - APAP pretreatment, group 3 - APAP+silymarin (extract of the silybum marianum with anti-inflammatory, anti-oxidant, and anti-fibrotic properties), group 4 - APAP+LCC1, group 5 - APAP+LCC2. The biomarkers of oxidative stress (nitric oxide and malondialdehyde) and antioxidant status of plasma (thiols and catalase), TNF-α, MMP-2 and MMP-9 serum levels were evaluated. RESULTS An improvement in oxidative stress, antioxidant status, and TNF-α, MMP-2 and MMP-9 levels was obtained in groups pretreated with LCC compared to silymarin treatment, in a dose-dependent manner. Histopathological examination reinforced the results. CONCLUSION Liposomal curcumin improves the oxidative stress/antioxidant balance and alleviates inflammation in experimental APAP-induced hepatotoxicity.

Abstract
α-lipoic acid (ALA) is a naturally occurring antioxidant with protective effects against various hepatic injuries. The aim of the present study was to investigate the mechanisms by which ALA protects the liver from carbon tetrachloride (CCl4)-induced liver cirrhosis. The widely used liver cirrhosis rat model was established via an intraperitoneal injection of 2 mg/kg 50% CCl4, three times/week for 8 weeks. Simultaneously, 50 or 100 mg/kg ALA was orally administrated to the rats every day for 8 weeks. The activity of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) was detected in the serum. The pathological liver injuries were analyzed using hematoxylin and eosin and Masson's trichrome staining. The principal factors involved in the transforming growth factor-β (TGF-β)/mothers against decapentaplegic homolog 9 (Smad3) and protein kinase B (AKT)/mammalian target of rapamycin (mTOR) pathways and in autophagy were examined using reverse transcription-quantitative polymerase chain reaction or western blot analysis. The results demonstrated that the administration of ALA alleviated CCl4-induced liver injury, as demonstrated by decreased ALT and AST activity, improved pathological injuries and reduced collagen deposition. The CCl4-induced increase in TGF-β and phosphorylated-Smad3 expression levels was additionally inhibited by treatment with ALA. Furthermore, the administration of ALA reversed the CCl4-induced upregulation of light chain 3II and Beclin-1, and downregulation of p62. The CCl4-induced suppression of the AKT/mTOR pathway was additionally restored following treatment with ALA. In combination, the results of the present study demonstrated that ALA was able to protect CCl4-induced liver cirrhosis, an effect that may be associated with inactivation of the TGF-β/Smad3 pathway and suppression of autophagy.

Abstract
Phaleria macrocarpa is one of the Indonesian herbal plants which has been shown to have a hepatoprotective effect. This study was conducted to evaluate the protective effect of water extract of mahkota dewa (Phaleria macrocarpa) in liver fibrosis and to elucidate its mechanism of action. Male Sprague-Dawley rats were treated with carbon tetrachloride (CCl4) for 8 weeks to induce liver fibrosis. Rats were randomly divided into 6 groups (n=5), i.e., control group, CCl4 group, CCl4 + NAC group, CCl4 + various doses of water extract of Phaleria macrocarpa (50, 100, and 150 mg/kg body weight). Aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), liver histopathology, malondialdehyde (MDA), ratio GSH/GSSG, Tumor Necrosis Factor- (TNF-) α, and Transforming Growth Factor- (TGF-) β 1 were analyzed. This study demonstrated that water extract of Phaleria macrocarpa and NAC significantly protected CCl4-induced liver injury as demonstrated by reduced AST, ALT, ALP, and fibrosis percentage compared with the CCl4-only group. In addition, water extract of Phaleria macrocarpa and NAC significantly reduced the levels of MDA, TNF-α, and TGF-β 1 as well as increasing the ratio of GSH/GSSG. Water extract of Phaleria macrocarpa prevents CCl4-induced fibrosis in rats. The prevention of liver fibrosis was at least in part through its antioxidant and anti-inflammatory activities and through its capacity to inhibit hepatic stellate cells (HSC) activation by reducing fibrogenic cytokine TGF-β 1.

Astragaloside Inhibits Hepatic Fibrosis by Modulation of TGF- β1/Smad Signaling Pathway. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2018; 2018:3231647.

Abstract
Activation of HSC is a pivotal step in hepatic fibrosis. In the activation of HSC, the TGF-β1 plays a key role that can promote the occurrence of hepatic fibrosis by combining with Smad proteins. Astragaloside is the main active component extracted from Radix Astragali that has the effect of antioxidation and hepatoprotection. In the present study, we investigated the mechanism of astragalosides inhibiting hepatic fibrosis in vitro and in vivo. In vitro, astragalosides inhibited the activation of HSC and regulated the expression of MMP-2 and TIMP-2 and reduced the formation of collagen fibers. In vivo, administration of astragalosides decreased the serum ALT, AST, and TBiL in rats by reducing oxidative stress. Astragalosides also attenuated hepatic fibrosis by reducing the concentration of hydroxyproline and inhibiting the formation of collagen fibers. The expressions of TGF-β1, TβR-I, p-Smad 2, and p-Smad 3 were downregulated after astragalosides treatments, while Smad 7 was upregulated compared to the control group. The results indicated that the effect of astragaloside on hepatic fibrosis was related to the inhibition of HSC activation and the modulation of the TGF-β1/Smad signaling pathway.

Abstract
This study aimed to investigate the possible protective role of curcumin (CUR) vs. N-acetyl cysteine (NAC) against paracetamol (PCM)-induced oxidative damage and impairment of liver, kidney, and testicular functions, as well as hematotoxicity, in albino rats. A large single dose of PCM induced lipid peroxidation along with a significant decline in glutathione content and catalase activity in the liver, kidneys, and testicles. The apparent oxidative damage was associated with evident hepatic, renal, and testicular dysfunction, which was confirmed in histopathological lesions, and increased serum aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase activities. PCM decreased serum total protein, albumin, and globulin contents; increased bilirubin, urea, and creatinine contents; and induced hematotoxicity. PCM also reduced the sperm cell count, sperm motility, and alive sperm rate and increased the sperm abnormality rate. Pretreatment of PCM-intoxicated animals with CUR or NAC substantially alleviated the increase in malondialdehyde and maintained the antioxidants at control levels. These pretreatments also minimized liver, kidney, and testicular histopathological changes and normalized their functions. CUR similarly mitigated the PCM hemato- and hepatotoxicity compared with NAC. However, it exhibited a pronounced nephroprotection, rather than reproductive protection as did NAC. Our findings demonstrate that a large single dose of PCM is not only associated with hepatotoxicity but also nephrotoxicity and reproductive toxicity. Both CUR and NAC administration provided substantial organ protection with pronounced efficacy against PCM nephrotoxicity with CUR and reproductive toxicity with NAC, which was possibly mediated through their antioxidant activities, as well as their specific characteristics.

Abstract
Radiation-induced fibrosis (RIF) is one of the most common late complications of radiation therapy. We found that α-lipoic acid (α-LA) effectively prevents RIF. In RIF a mouse model, leg contracture assay was used to test the in vivo efficacy of α-LA. α-LA suppressed the expression of pro-fibrotic genes after irradiation, both in vivo and in vitro, and inhibited the up-regulation of TGF-β1-mediated p300/CBP activity. Thus, α-LA prevents radiation-induced fibrosis (RIF) by inhibiting the transcriptional activity of NF-κB through inhibition of histone acetyltransferase activity. α-LA is a new therapeutic methods that can be used in the prevention-treatment of RIF.

Abstract
Liver fibrosis is an excess production of extracellular matrix proteins as a result of chronic liver disease which leads to cell death and organ dysfunction. The key cells involved in fibrogenesis are resident hepatic stellate cells (HSCs) which are termed myofibroblasts after activation, acquiring contractile, proliferative, migratory and secretory capability. Sphingosine 1-phosphate (S1P) is a bioactive sphingolipid with well-established effects on angiogenesis, carcinogenesis and immunity. Accumulating evidence demonstrates that this metabolite is involved in the profibrotic inflammatory process through the regulation of pleiotropic cell responses, such as vascular permeability, leukocyte infiltration, cell survival, migration, proliferation and HSCs differentiation to myofibroblasts. S1P is synthesized by sphingosine kinases (SphKs) and many of its actions are mediated by S1P specific cell surface receptors (S1P1-5), although different intracellular targets of S1P have been identified. Modulation of SphKs/S1P/S1P receptors signaling is known to result in beneficial effects on various in vivo and in vitro models of liver fibrosis. Thus, a better knowledge of the molecular mechanisms involved in the modulation of the S1P pathway could help to improve liver fibrosis therapy. In this review, we analyze the effects of the S1P axis on the fibrogenic process, and the involvement of a range of inhibitors or approaches targeting enzymes related to S1P in the abrogation of pathological fibrogenesis. All in all, targeting this pathway offers therapeutic potential in the treatment of hepatic fibrosis.

Abstract
Prenatal ethanol exposure causes the most frequent preventable birth disorder, fetal alcohol spectrum disorder (FASD). The effect of turmeric extracts in rescuing an ethanol-induced developmental defect using zebrafish as a model was determined. Ethanol-induced oxidative stress is one of the major mechanisms underlying FASD. We hypothesize that antioxidant inducing properties of turmeric may alleviate ethanol-induced defects. Curcuminoid content of the turmeric powder extract (5 mg/mL turmeric in ethanol) was determined by UPLC and found to contain Curcumin (124.1 ± 0.2 μg/mL), Desmethoxycurcumin (43.4 ± 0.1 μg/mL), and Bisdemethoxycurcumin (36.6 ± 0.1 μg/mL). Zebrafish embryos were treated with 100 mM (0.6% v/v) ethanol during gastrulation through organogenesis (2 to 48 h postfertilization (hpf)) and supplemented with turmeric extract to obtain total curcuminoid concentrations of 0, 1.16, 1.72, or 2.32 μM. Turmeric supplementation showed significant rescue of the body length at 72 hpf compared to ethanol-treated embryos. The mechanism underlying the rescue remains to be determined.

Abstract
The tyrosine kinase inhibitor erlotinib targets the receptor of epidermal growth factor (EGFR) involved in development of hepatocellular carcinoma (HCC). Although inefficient in established HCC, erlotinib has been recently proposed for HCC chemoprevention. Since Cyp3A4 and Cyp1A2 enzymes metabolize erlotinib in the liver, the insights into the mechanisms of erlotinib effects on liver cells with maintained drug metabolizing activity are needed. We applied erlotinib to both commercially available (SNU398, Huh7) and established in Austria HCC cell lines (HCC-1.2, HCC-3). Cyp3A4 and Cyp1A2, microarray gene expression, cell viability, LDH release, DHFC fluorescence were assessed. VEGF expression was analysed by real-time RT-PCR and ELISA. Higher cumulative expression of erlotinib metabolizing enzymes was observed in HCC-1.2 and HCC-3 cells. Gene expression microarray analysis showed upregulation of VEGF signalling by erlotinib. VEGF was increased up to 134 ± 14% (n = 5, p = 0.002) in HCC-1.2, HCC-3 and Huh7 cells. Interventions by Cyp1A2 and Mek2siRNA, MEK inhibitor UO126, diphenylene iodonium, as well as a combination of N-acetylcysteine with selenium all inhibited VEGF upregulation caused by erlotinib. Thus, erlotinib increases VEGF production by mechanisms involving Cyp1A2, oxidative stress and MEK1/2. VEGF may favour angiogenesis and growth of early HCC tumours limiting the therapeutic and chemopreventive effects of erlotinib.

Abstract
BACKGROUND Liver fibrosis is a noteworthy well-being issue that can prompt the progression of liver cirrhosis and hepatocellular carcinoma. Prominently, many antioxidants have been shown to have defensive impacts against liver fibrosis. AIM Subsequently, in the present study, the viability of alpha-lipoic acid (α-LA) in ensuring against carbon tetrachloride (CCl4)-actuated liver fibrosis and the mechanism(s) involved in this defensive impact were considered in rats. RESULTS The present results uncovered that in the CCl4-treated group, the expression of antioxidant enzymes and matrix metalloproteinase-13 (MMP-13) messenger RNA (mRNA) was downregulated ( p < 0.05), and the levels of lipid peroxide and nitric oxide were increased ( p < 0.05) in the treated rat livers along with increased collagen deposition compared to that of the control group. Also, the gene expression levels of the proinflammatory factors interleukin-6 and tumor necrosis factor-alpha, nuclear factor-kappa B (NF-κB) p65, transforming growth factor-alpha, and inducible nitric oxide synthase (iNOS) were upregulated significantly ( p < 0.05) in the CCl4 group. These negative impacts were all restrained by α-LA. CONCLUSIONS These outcomes show that α-LA might be compelling at forestalling collagen deposition and hepatic oxidative stress as well as downregulating the expression of hepatic proinflammatory cytokines, iNOS, and NF-κB and upregulating MMP-13 expression.

Abstract
The present research task is aimed to evaluate the role of exogenous α-lipoic acid (ALA) (100 mg/kg body weight) as hepatoprotective and potent antioxidant in amelioration of copper nanoparticle (CNP)-induced hepatotoxicity. Forty male rats were randomly assigned into four equal groups: group I (control), group II received CNPs, group III received CNPs + ALA, and finally group IV received ALA for 2 months. At the end of the experimental period, the rats were decapitated, and blood and liver tissue samples were collected for measurement of liver function tests, antioxidant status, lipid peroxidation (LPO), copper content, expression of some apoptotic genes, and histopathological analysis. CNPs induced marked hepatic damages as evident by severe alteration in hepatic biomarkers. This was accompanied by a significant elevation in hepatic LPO and induced nitric oxide, copper content, and expression level of apoptotic genes (C-myc and C-jun). In contrast, marked depletion for antioxidant parameters was detected. These findings were confirmed with severe pathological alterations. Coadministration of ALA as a powerful antioxidant attenuates the hepatotoxic effects of CNPs through improvement of liver parameters, oxidative status, genetic changes, and preservation of liver integrity through histopathological analysis. These results suggest that consumed ALA could be used as an applicable hepatoprotective agent against oxidative damage mediated by nanoparticles intoxication.

Abstract
Sustained activation of hepatic stellate cells (HSCs) leads to liver fibrosis. Autophagy fuels the activation of HSCs by generation of ATP. Our previous research demonstrated an inhibitory effect of dimethyl α-ketoglutarate (DMKG) on HSCs activation in vitro. In the current study, we demonstrated that DMKG reduced CCl4-induced liver fibrosis in Wistar rats. Then, with the use of the HSC-T6 cell lines and double immunofluorescent staining of liver sections, we showed that the anti-fibrotic effect occurred through the inhibition of the autophagy of HSCs. Both experiments showed that DMKG could inhibit autophagy and activation of HSCs, and that the activation of HSCs was down-regulated with autophagy. In addition, we showed that DMKG could lead to lipid droplet accumulation and decrease cellular ATP content in HSCs. Furthermore, the mechanism of how DMKG inhibited autophagy of HSCs was explored in vitro with the use of c646 (a competitive inhibitor of acetyl-coenzyme A which binds to the acetyltransferase EP300) and lipoic acid (an alternative acetyl-coenzyme A -replenishing agent to DMKG), and showed that both acetyl-coenzyme A and EP300 were involved. Collectively, our study investigated the possible role of DMKG in preventing liver fibrosis and HSCs activation. We showed that DMKG may be a potential therapeutic agent for the treatment of liver fibrosis.

Abstract
The liver is intimately connected to inflammation, which is the innate defense system of the body for removing harmful stimuli and participates in the hepatic wound-healing response. Sustained inflammation and the corresponding regenerative wound-healing response can induce the development of fibrosis, cirrhosis and eventually hepatocellular carcinoma. Oxidative stress is associated with the activation of inflammatory pathways, while chronic inflammation is found associated with some human cancers. Inflammation and cancer may be connected by the effect of the inflammation-fibrosis-cancer (IFC) axis. Chinese medicinal herbs display abilities in protecting the liver compared to conventional therapies, as many herbal medicines have been shown as effective anti-inflammatory and anti-oxidative agents. We review the relationship between oxidative stress and inflammation, the development of hepatic diseases, and the hepatoprotective effects of Chinese medicinal herbs via anti-inflammatory and anti-oxidative mechanisms. Moreover, several Chinese medicinal herbs and composite formulae, which have been commonly used for preventing and treating hepatic diseases, including Andrographis Herba, Glycyrrhizae Radix et Rhizoma, Ginseng Radix et Rhizoma, Lycii Fructus, Coptidis Rhizoma, curcumin, xiao-cha-hu-tang and shi-quan-da-bu-tang, were selected for reviewing their hepatoprotective effects with focus on their anti-oxidative and ant-inflammatory activities. This review aims to provide new insight into how Chinese medicinal herbs work in therapeutic strategies for liver diseases.

Abstract
Chronic liver disease, depicted by gradual destruction and fibrosis of the liver, is a condition with high and probably increasing prevalence worldwide. Its deterioration, acute-on-chronic liver failure (ACLF), is characterized by an in-hospital mortality of up to 65%. Infectious complications are the main precipitants eliciting ACLF and concurrently the main cause of death from ACLF. Patients have a marked susceptibility to bacterial infections, which is thought to arise a consequence of an inadequate immune response to microbial challenge, termed immuneparesis. The pathophysiologic mechanisms remain poorly understood. Treatments aimed at restoring the patients' immune function may prevent onset of ACLF and death from secondary infections. A number of drugs approved for patients with liver disease bear immunomodulatory potential such as albumin, glucocorticoids, N-acetylcysteine. Specific targets have been defined that may lead to development of new immunotherapeutic agents. Here, we summarize the pathophysiology of immuneparesis in ACLF and drug candidates to restore immune function and improve survival in the future.

Abstract
Nonalcoholic steatohepatitis (NASH) is the advanced form of nonalcoholic fatty liver disease, which is often accompanied by obese and/or type II diabetes mellitus. Approximately one-third of NASH patients develop hepatic fibrosis. Hepatic stellate cells are the major effector cells during liver fibrogenesis. Advanced liver fibrosis usually proceeds to cirrhosis and even hepatocellular carcinoma, leading to liver failure, portal hypertension and even death. Currently, there are no approved agents for treatment and prevention of liver fibrosis in human beings. Curcumin, the principal curcuminoid of turmeric, has been reported to show antitumor, antioxidant, and anti-inflammatory properties both in in vitro and in vivo systems. Accumulating data shows that curcumin plays a critical role in combating liver fibrogenesis. This review will discuss the inhibitory roles of curcumin and update the underlying mechanisms by which curcumin targets in inhibiting hepatic stellate cell activation.

Abstract
Acute kidney injury is a frequent and serious complication in patients with severe sepsis. α-Lipoic acid (ALA), a naturally occurring dithiol compound, has been shown to possess anti-inflammatory and anti-oxidative properties. In the present study we investigated whether ALA could attenuate acute kidney injury and improve survival in a rat model of sepsis. Rats were subjected to caecal ligation and puncture (CLP) to induce sepsis. α-Lipoic acid (200 mg/kg) was administered by oral gavage either immediately (early treatment) or 12 h after the surgical procedure (delayed treatment). Both early and delayed ALA treatment effectively prolonged survival, improved pathological damage in kidney tissues and reduced serum blood urea nitrogen and creatinine levels in CLP-induced septic rats. Furthermore, early treatment with ALA markedly inhibited the release of tumour necrosis factor-α, interleukin (IL)-6 and IL-1β into the serum and reduced mRNA and protein expression of inducible nitric oxide synthase and high mobility group box 1 in kidney tissues from CLP-induced rats. Finally, CLP-induced nuclear factor-κB activation in kidney tissues was significantly suppressed by early ALA treatment. Together, the results indicate that ALA is able to reduce mortality and attenuate acute kidney injury associated with sepsis, possibly by anti-inflammatory actions. α-Lipoic acid may be a promising novel agent for the treatment of conditions associated with septic shock.

Abstract
PURPOSE To evaluate the efficacy of α-lipoic acid (ALA) in reducing scarring after trabeculectomy. MATERIALS AND METHODS Eighteen adult New Zealand white rabbits underwent trabeculectomy. During trabeculectomy, thin sponges were placed between the sclera and Tenon's capsule for 3 minutes, saline solution, mitomycin-C (MMC) and ALA was applied to the control group (CG) (n=6 eyes), MMC group (MMCG) (n=6 eyes), and ALA group (ALAG) (n=6 eyes), respectively. After surgery, topical saline and ALA was applied for 28 days to the control and ALAGs, respectively. Filtrating bleb patency was evaluated by using 0.1% trepan blue. Hematoxylin and eosin and Masson trichrome staining for toxicity, total cellularity, and collagen organization; α-smooth muscle actin immunohistochemistry staining performed for myofibroblast phenotype identification. RESULTS Clinical evaluation showed that all 6 blebs (100%) of the CG had failed, whereas there were only 2 failures (33%) in the ALAG and no failures in the MMCG on day 28. Histologic evaluation showed significantly lower inflammatory cell infiltration in the ALAGs and CGs than the MMCG. Toxicity change was more significant in the MMCG than the control and ALAGs. Collagen was better organized in the ALAG than control and MMCGs. In immunohistochemistry evaluation, ALA significantly reduced the population of cells expressing α-smooth muscle action. CONCLUSIONS ΑLA prevents and/or reduces fibrosis by inhibition of inflammation pathways, revascularization, and accumulation of extracellular matrix. It can be used as an agent for delaying tissue regeneration and for providing a more functional-permanent fistula.

Abstract
During chronic liver injury, hepatic stellate cells (HSC) are activated and proliferate, which causes excessive extracellular matrix (ECM) deposition, leading to scar formation and fibrosis. Medicinal plants are gaining popularity as antifibrotic agents, and are often safe, cost-effective, and versatile. This review aims to describe the protective role and mechanisms of medicinal plants in the inhibition of HSC activation and ECM deposition during the pathogenesis of liver fibrosis. A systematic literature review on the anti-fibrotic mechanisms of hepatoprotective plants was performed in PubMed, which yielded articles about twelve relevant plants. Many of these plants act via disruption of the transforming growth factor beta 1 signaling pathway, possibly through reduction in oxidative stress. This reduction could explain the inhibition of HSC activation and reduction in ECM deposition. Medicinal plants could be a source of anti-liver fibrosis compounds.

Abstract
Background An overdose of paracetamol is a frequent reason for liver and renal toxicity and possible death and curcumin has hepatoprotective properties against liver damage. The exact mechanism of such protection is not clear. Therefore, this study was conducted to examine the molecular levels of the protective effect of curcumin on paracetamol overdose induced hepatic toxicity in rats. Methods Male Wistar rats were allocated into 4 groups. Control group, administered corn oil; curcumin group, administered curcumin (400 mg/kg BW daily intra-gastric) dissolved in corn oil; paracetamol group, administered corn oil with a single dose of paracetamol (500 mg/kg BW intra-gastric) and protective group, administered curcumin with a single dose of paracetamol. Curcumin was administered for 7 successive days, while paracetamol was administered at day six of treatment. Blood and liver tissues were collected for biochemical, histopathological, immunohistochemical and molecular examination. Results Serum analysis revealed an alteration in parameters of kidney and liver. A decrease in the antioxidant activity of liver was recorded in paracetamol group while curcumin administration restored it. Histopathological findings showed an extensive coagulative necrosis in hepatocytes together with massive neutrophilic and lymphocytic infiltration. Immunostaining of liver matrix metalloproteinase-8 (MMP-8) in paracetamol administered rats showed an increase in MMP-8 expression in the area of coagulative necrosis surrounding the central vein of hepatic lobules. Curcumin administration decreased MMP-8 expression in liver of paracetamol administered rats. Gene expression measurements revealed that paracetamol decreased the expression of antioxidant genes and increased the expression of interleukin-1β (IL-1β), IL-8, tumor necrosis factor-α (TNF-α) and acute phase proteins. Curcumin administration ameliorated paracetamol-induced alterations in genes expression of antioxidant and inflammatory cytokines. Conclusion The results clarified the strong protective effect of curcumin on paracetamol induced hepatic toxicity in rats at the immunohistochemical and molecular levels.

Abstract
Alpha-lipoic acid (ALA) is a natural dithiol compound, with a free radical scavenger and biological antioxidant properties. The purpose of the current study was to investigate the protective effects of ALA on biochemical alteration and oxidative stress induced by acute deltamethrin intoxication in rats. Markers of liver and kidney injuries in serum of deltamethrin-intoxicated as well as ALA-pretreated rats were analyzed. Moreover, serum and (or) tissue lipid peroxidation, malondialdehyde and antioxidant markers, reduced glutathione, catalase, superoxide dismutase activity, and total antioxidant capacity were evaluated. The results showed that all parameters were altered in the intoxicated group, indicating hepatorenal oxidative damage of deltamethrin. Pre-treatment with ALA reversed the changes in most of the studied parameters in a dose-dependent manner. Histopathological and biochemical findings were parallel. It can be concluded that ALA may be a promising therapeutic option for prevention and (or) treatment of deltamethin toxicity.

Abstract
Hepatic fibrosis is concomitant with sinusoidal pathological angiogenesis, which has been highlighted as novel therapeutic targets for the treatment of chronic liver disease. Our prior studies have demonstrated that curcumin has potent antifibrotic activity, but the mechanisms remain to be elucidated. The current work demonstrated that curcumin ameliorated fibrotic injury and sinusoidal angiogenesis in rat liver with fibrosis caused by carbon tetrachloride. Curcumin reduced the expression of a number of angiogenic markers in fibrotic liver. Experiments in vitro showed that the viability and vascularization of rat liver sinusoidal endothelial cells and rat aortic ring angiogenesis were not impaired by curcumin. These results indicated that hepatic stellate cells (HSCs) that are characterized as liver-specific pericytes could be potential target cells for curcumin. Further investigations showed that curcumin inhibited VEGF expression in HSCs associated with disrupting platelet-derived growth factor-β receptor (PDGF-βR)/ERK and mTOR pathways. HSC motility and vascularization were also suppressed by curcumin associated with blocking PDGF-βR/focal adhesion kinase/RhoA cascade. Gain- or loss-of-function analyses revealed that activation of peroxisome proliferator-activated receptor-γ (PPAR-γ) was required for curcumin to inhibit angiogenic properties of HSCs. We concluded that curcumin attenuated sinusoidal angiogenesis in liver fibrosis possibly by targeting HSCs via a PPAR-γ activation-dependent mechanism. PPAR-γ could be a target molecule for reducing pathological angiogenesis during liver fibrosis.

Abstract
Amphibians are known to better tolerate and endure adverse environmental conditions such as redox imbalances conferred by reactive oxygen species (ROS), compared to mammals. Interestingly, the exact adaptation strategies and signaling mechanisms mediating these effects have not been fully elucidated. Therefore, in the present study, we probed into the molecular response of the isolated perfused Rana ridibunda heart to curcumin, in the context of mitogen-activated protein kinases (MAPKs) phosphorylation patterns and apoptotic markers occurrence. In particular, this polyphenol was found to exert a pro-oxidant effect in our model and to significantly upregulate p38-MAPK and JNKs phosphorylation (thus activation). The early apoptosis observed, substantiated by poly(ADP-ribose) polymerase (PARP) cleavage, was established to be JNKs- and ROS-mediated, while no involvement of p38-MAPK was detected. Subsequently, the pro-oxidative activity of curcumin was confirmed to mimic H(2) O(2). Furthermore, NADPH oxidase as well as Na(+) /K(+) -ATPase were found to mediate JNKs phosphorylation as well as PARP proteolytic cleavage. Curcumin exerts pleiotropic actions, both beneficial and detrimental and is currently the subject of intense scientific research. Being a low-molecular-weight antioxidant, it is intriguing to investigate curcumin's role in redox homeostasis in the amphibian heart, under conditions that apparently favor its pro-oxidative properties. Comparative studies of its multifaceted role in different species may contribute to the clarification of the signaling mechanisms it triggers and the terminal physiological response it confers. Collectively, this is to our knowledge, the first time that the signal transduction pathways stimulated by curcumin have been assessed in a non-mammalian species.

Abstract
Over the last 10 years curcumin has been reported to be effective against a wide variety of diseases and is characterized as having anticarcinogenic, hepatoprotective, thrombosuppressive, cardioprotective, antiarthritic, and anti-infectious properties. Recent studies performed in both vertebrate and invertebrate models have been conducted to determine whether curcumin was also neuroprotective. The efficacy of curcumin in several preclinical trials for neurodegenerative diseases has created considerable excitement mainly because of its lack of toxicity and low cost. This suggests that curcumin could be a worthy candidate for nutraceutical intervention. As aging is a common risk factor for neurodegenerative diseases, it is possible that some compounds that target aging mechanisms could also prevent these kinds of diseases. One potential mechanism to explain several of the general health benefits associated with curcumin is that it may prevent aging-associated changes in cellular proteins that lead to protein insolubility and aggregation. This loss in protein homeostasis is associated with several age-related diseases. Recently, curcumin has been found to help maintain protein homeostasis and extend lifespan in the model invertebrate Caenorhabditis elegans. Here, we review the evidence from several animal models that curcumin improves healthspan by preventing or delaying the onset of various neurodegenerative diseases.

Abstract
Using antioxidants is an important means of treating lead poisoning. Prior in vivo studies showed marked differences between various chelator antioxidants in their ability to decrease both blood Pb(II) levels and oxidative stress resulting from lead poisoning. The comparative abilities of NAC and NACA to Pb(II) were studied in vitro, for the first time, to examine the role of the -OH/-NH(2) functional group in antioxidant binding behavior. To assay the antioxidant-divalent metal interaction, the antioxidants were probed as solid surfaces, adsorbing Pb(II) onto them. Surface characterization was carried out using X-ray photoelectron spectroscopy (XPS) analysis to quantify Pb(II) in the resulting adducts. XPS of the Pb 4f orbitals showed that more Pb(II) was chemically bound to NACA than NAC. In addition, the antioxidant surfaces probed via point-of-zero charge (PZC) measurements of NAC and NACA were obtained to gain further insight into the Pb-NAC and Pb-NACA binding, showing that Coulombic interactions played a partial role in facilitating complex formation. The data correlated well with solution analysis of metal-ligand complexation. UV-vis spectroscopy was used to probe complexation behavior. NACA was found to have the higher binding affinity as shown by free Pb(II) available in the solution after complexation from HPLC data. Electrospray ionization mass spectrometry (ESI-MS) was applied to delineate the structures of Pb-antioxidant complexes. Experimental results were further supported by density functional theory (DFT) calculations of supermolecular interaction energies (E(inter)) showing a greater interaction of Pb(II) with NACA than NAC.
