[PMID: 25533183 DOI: 10.1002/tox.22101] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/29/2014] [Revised: 12/05/2014] [Accepted: 12/07/2014] [Indexed: 06/04/2023]
Abstract
The present study was aimed to investigate the mechanistic aspect of Aroclor 1260-induced hepatotoxicity and its protection by lipoic acid. The adult male Albino rats were divided into six groups. Group I served as control. Group II received lipoic acid (35 mg/kg/day). Aroclor 1260 was given to rats by oral gavage at doses 20, 40, or 60 mg/kg/day (Groups III, IV, and V, respectively). Group VI was pretreated with lipoic acid (35 mg/kg/day) 24 h before Aroclor 1260 (40 mg/kg/day). Treatment in all groups was continued for further 15 consecutive days. Serum alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and lactate dehydrogenase activities and total bilirubin, total cholesterol, and triglycerides were significantly increased while total protein, total albumin, and high-density lipoprotein were significantly decreased. Hydrogen peroxide production and lipid peroxidation were significantly increased while superoxide dismutase and catalase activities and reduced glutathione (GSH) content was significantly decreased in liver. Caspase-3 & -9 activities were significantly increased in liver. Lipoic acid pretreatment significantly reverted all these abnormalities toward their normal levels. In conclusion, Aroclor 1260 induced liver dysfunction, at least in part, by induction of oxidative stress. Apoptotic effect of hepatic cells is involved in Aroclor 1260-induced liver injury. Lipoic acid could protect rats against Aroclor 1260-induced hepatotoxicity. © 2014 Wiley Periodicals, Inc. Environ Toxicol 31: 913-922, 2016.

Abstract
Background The liver performs diverse functions that are essential for life. In the absence of reliable liver protective drugs, a large number of natural medicinal preparations are used for the treatment of liver diseases. Therefore the present study aims to investigate the hepatoprotective effects of Salix subserrata Willd flower ethanolic extract (SFEE) against carbon tetrachloride (CCl4)-induced liver damage. Methods Rats were divided into 4 groups of 10 animals each. Group I served as the normal healthy control, groups II rats were intoxicated with CCl4 i.p. (0.8 ml/kg body weight CCl4/olive oil, twice weekly for 9 weeks), group III rats received CCl4 i.p. and SFEE orally (150 mg/kg daily) and group IV rats received CCl4 i.p. and Silymarin orally (100 mg/kg, daily). The hepatoprotective potential of SFEE in rats was evaluated by measuring the protein levels of two inflammatory biomarkers; tumor necrosis factor-alpha (TNF-α) and nuclear factor kappa-B (NF-kB) in addition to other liver biomarkers. Histopathological changes in the liver were assessed using hematoxylin and eosin staining (HE). Results The administration of SFEE showed hepatic protection at an oral dose of 150 mg/kg. SFEE significantly reduced the elevated serum levels of intracellular liver enzymes as well as liver biomarkers in comparison to CCl4− intoxicated group. Notably, SFEE significantly reduced the expression levels of TNF-α and NFkB proteins compared to their levels in CCl4 intoxicated group. These findings were confirmed with the histopathological observations, where SFEE was capable of reversing the toxic effects of CCl4 on liver cells compared to that observed in CCl4-intoxicated animals. Conclusion Our results show that SFEE has potential hepatoprotective effects at 150 mg/kg. These effects can be regarded to the antioxidant and anti-inflammatory properties of the extract.

Protective Effect of the Total Flavonoids from Rosa laevigata Michx Fruit on Renal Ischemia-Reperfusion Injury through Suppression of Oxidative Stress and Inflammation. Molecules 2016; 21:molecules21070952. [PMID: 27455216 PMCID: PMC6272996 DOI: 10.3390/molecules21070952] [Citation(s) in RCA: 53] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2016] [Revised: 07/09/2016] [Accepted: 07/19/2016] [Indexed: 01/20/2023] Open
Abstract
Renal ischemia-reperfusion injury (IRI) is a major cause of acute kidney injury (AKI). Our previous studies have shown that the total flavonoids (TFs) from Rosa laevigata Michx fruit has various activities, however, there were no papers reporting the role of the TFs against renal IRI. In the present work, a hypoxia/reoxygenation (H/R) model in NRK-52E cells and ischemia-reperfusion model in rats were used. The results showed that the TFs significantly attenuated cell injury and markedly decreased serum creatinine (Cr) and blood urea nitrogen (BUN) levels in rats. Further investigation revealed that the TFs markedly decreased the levels of malondialdehyde (MDA), superoxide dismutase (SOD), glutathione (GSH) and glutathione peroxidase (GSH-Px) and intracellular reactive oxygen species (ROS), up-regulated the levels of silent information regulator factor 2-related enzyme 1 (Sirt1), nuclear factor erythroid 2-related factor-2 (Nrf2) and heme oxygenase-1 (HO-1), down-regulated the levels of Kelch like ECH-associated protein-1 (Keap1) and the nuclear translocation of nuclear factor-κBp65 (NF-κBp65), and decreased the mRNA levels of interleukine-1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α). Furthermore, inhibiting Sirt1 by siRNA showed that the role of the natural product in protecting renal IRI was significantly attenuated, suggesting that the effect of the extract against renal IRI depended on Sirt1. Taken together, the TFs has significantly nephroprotective effect against IRI by affecting Sirt1/Nrf2/NF-κB signaling pathway, which should be developed as a new therapeutic agent or food additives to treat acute kidney injury in the future.

Abstract
Hepatorenal toxicities are an important side effect of anthracycline antibiotics. The objective of this study was to determine whether sesamin (Ses) protects against acute doxorubicin (DOX)-induced hepatorenal toxicities. Rats received daily treatment with either 0.5% carboxymethylcellulose (10 mL/kg) or Ses (10, 20 and 40 mg/kg) orally for 10 days, followed by an intravenous injection at day 8 of either saline (10 mL/kg) or DOX (20 mg/kg). Hepatorenal toxicity was assessed by measuring the levels of serum creatinine (Cre), blood urea nitrogen (BUN), aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP). The protein expression of 4-hydroxynonenal (4-HNE) in hepatorenal tissues was evaluated using immunohistochemistry. The malondialdehyde (MDA) content and antioxidant activity in the kidney and liver tissues were also measured. The results suggest that pretreatment with Ses ameliorated DOX-induced liver and kidney injury by lowering the serum ALT, AST, ALP, Cre and BUN levels ( p < 0.05 or p < 0.01), and the histological damage to the liver and kidney tissues induced by DOX compared to control were also significantly attenuated by Ses. Furthermore, Ses significantly decreased the DOX-induced increase of MDA and 4-HNE and increased the activity of CAT, SOD and GPX compared to the DOX-treated rats ( p < 0.05 or p < 0.01), whereas the change of DOX + Ses (10 mg/kg) group is not significant compared to the DOX-treated group ( p > 0.05). These findings indicate that Ses elicits a typical protective effect against DOX-induced acute hepatorenal toxicity via the suppression of oxidative stress.

Total Flavonoids from Rosa laevigata Michx Fruit Ameliorates Hepatic Ischemia/Reperfusion Injury through Inhibition of Oxidative Stress and Inflammation in Rats. Nutrients 2016; 8:nu8070418.

Abstract
The effects of total flavonoids (TFs) from Rosa laevigata Michx fruit against liver damage and cerebral ischemia/reperfusion (I/R) injury have been reported, but its action on hepatic I/R injury remains unknown. In this work, the effects and possible mechanisms of TFs against hepatic I/R injury were examined using a 70% partial hepatic warm ischemia rat model. The results demonstrated TFs decreased serum aspartate transaminase (AST), alanine aminotransferase (ALT), myeloperoxidase (MPO), and lactate dehydrogenase (LDH) activities, improved liver histopathology and ultrastructure through hematoxylin-eosin (HE) staining and electron microscope observation. In addition, TFs significantly decreased malondialdehyde (MDA) and increased the levels of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), which indicated that TFs alleviated oxidative stress caused by I/R injury. RT-PCR results proved that TFs downregulated the gene levels of inflammatory factors including interleukin-1 beta (IL-1β), interleukin-1 (IL-6), and tumor necrosis factor alpha (TNF-α). Further research indicated that TF-induced hepatoprotection was completed through inhibiting TLR4/MyD88 and activating Sirt1/Nrf2 signaling pathways. Blockade of the TLR4 pathway by TFs inhibited NF-κB and AP-1 transcriptional activities and inflammatory reaction. Activation of Sirt1/Nrf2 pathway by TFs increased the protein levels of HO-1 and GST to improve oxidative stress. Collectively, these findingsconfirmed the potent effects of TFs against hepatic I/R injury, which should be developed as a candidate for the prevention of this disease.

Abstract
UNLABELLED Trillin is an active ingredient isolated from Dioscorea nipponica Makino. This study investigated the anti-inflammatory and anti-fibrosis effects of trillin on CCl4-induced hepatotoxicity in C57BL/6 mice. Chronic inflammation and fibrosis were induced by intraperitoneal administration of CCl4 0.5 μL/g of body weight twice a week for 6 weeks. Trillin (50 mg/kg, 100 mg/kg) was administered by gavage for 12 days before finishing the CCl4 induction. Aspartate amino-transferase (AST) and glutamic-pyruvic transaminase (ALT) in serum were determined by AST and ALT kits. Superoxidase dismutase (SOD) activity and malondialdehyde (MDA) levels in serum were assayed by SOD and MDA kits. Meanwhile, the levels of inflammatory mediators including tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β) in serum were detected by enzyme-linked immunosorbent assay (ELISA) method. Pathological changes were observed by hematoxylin-eosin (HE) staining. The proteins of the NF-κB pathway and the TGF-β/Smad pathway were measured by western blot. The trillin-treated group exhibited reduced AST, ALT, MDA, IL-6, TNF-α, and IL-1β, and increased SOD. Histological analyses of the trillin-treated group exhibited reduced inflammatory process and prevented liver fibrosis. Western blot analyses of the trillin-treated group showed reduced NF-κB pathway and TGF-β/Smad pathway. SIGNIFICANCE Based on the results of the present study, trillin can be used as a potential anti-inflammatory drug for chronic hepatic inflammation.

Abstract
PURPOSE In absence of liver protective drugs, a large number of hepatopathies may arise during drug administration. This study was executed to investigate the possible new pathways underlying the hepatoprotective effect of Tempol (4-hydroxy-2,2,6,6- tetramethylpiperidine-1-oxyl), following oral administration of carbon tetrachloride in mice. METHODS AND RESULTS Thirty albino mice were randomized into 3 equal groups. The duration of study was 28 days. The groups were classified as follows: Group I (healthy control): received saline, in the same volume of CCl4 dose, daily, orally, for 14 days, then sacrificed. Group II: received CCl4, as a single oral dose only, of 1 ml/kg body weight, dissolved in olive oil (1:1 v/v), the animals of this group were sacrificed 14 days after CCl4 single dose intoxication. Group III (protective Tempol treated): received a single dose of Tempol, 20mg/kg, orally, daily for 14 days. Two hours after the last Tempol dose, animals of group III received a single oral dose of CCl4. Fourteen days later, animals were scarified to collect blood and liver tissues for analysis. Tempol pretreatment significantly captured elevated levels of ALT and AST activities, lipid peroxidation, total bilirubin and increased total thiol and catalase contents. Notably, it significantly reduced the expression of tumor necrosis factor-alpha (TNF-α), Caspase-3 and endoplasmic reticulum (ER) inositol-requiring enzyme 1(IRE1) mRNAs, which is an ER trans membrane sensor that activates the unfolded protein response (UPR) to maintain the ER and cellular function. CONCLUSION Pretreatment with Tempol has potential hepatoprotective effects against acute liver injury, induced by CCl4, through antioxidant and anti-inflammatory activities.

Abstract
To investigate the toxicity, protective effects, and action mechanism of gallotannin-enriched extracts isolated from Galla Rhois (GEGR) against carbon tetrachloride (CCl₄)-induced hepatotoxicity in Institute for Cancer Research (ICR) mice, alterations in serum biochemical indicators, histopathological structure, antioxidative status, hepatic apoptosis-related proteins, and liver fibrosis regulating factors were measured in mice pretreated with GEGR for five days before CCl₄ injection. The GEGR/CCl₄ treated group showed decreased levels of three serum marker enzymes (ALP, AST, and ALT) representing liver toxicity, although LDH levels remained constant. Necrotic area indicating hepatic cell death significantly inhibited, while malondialdehyde (MDA) concentration and superoxide dismutase (SOD) expression were dramatically recovered in the GEGR preadministrated group. In mechanism analyses of GEGR, the formation of active caspase-3 and enhancement of Bax/Bcl-2 expression was effectively inhibited in the GEGR/CCl₄ treated group. The level of pro-inflammatory cytokines, TNF-α and IL-6, as well as the phosphorylation of p38 and JNK in the TNF-α downstream signaling pathway was rapidly recovered in the GEGR/CCl₄ treated group, while anti-inflammatory cytokine (IL-10) increased slightly in the same group. Furthermore, the GEGR/CCl₄ treated group showed a significant decrease in collagen accumulation results from alleviation of MMP-2 expression, TGF-β1 secretion and the phosphorylation of Smad2/3. Taken together, these results suggest that GEGR may induce remarkable protective effects against hepatic injury induced by CCl₄ treatment through upregulation of the anti-inflammatory and antioxidant system.

Abstract
Background The replacement of lost cardiac tissues by regenerated myocardium would be a therapeutic ideal for myocardial infarction. The objective of this study was therefore to evaluate the ability of an active fraction that was isolated from Rosa laevigata Michx in therapeutic cardiomyogenesis in a myocardial infarction rat model. Methods The myocardial infarction animal model was induced by the permanent ligation of the left anterior descending coronary artery in rats. The active fraction, which improves the survival rate and prevents ischemic reperfusion damage, was used to test the therapeutic effect of this fraction on myocardial infarction. Results The oral administration of the active fraction for 4 weeks could progressively restore the decreased cardiac function due to myocardial infarction. The significantly improved cardiac function was probably attributed to the active fraction-induced myocardial regeneration, which replaced the lost cardiac tissues in the myocardial infarction animals. Conclusions The property of this active fraction appears to be entirely novel and may provide a potential therapeutic alternative for myocardial infarction.

Abstract
Sesamin, a major lignan derived from sesame seeds, has been reported to have many benefits and medicinal properties. However, its protective effects against fluoride-induced injury in kidney of fish have not been clarified. Previously we found that fluoride exposure caused damage and apoptosis in the kidneys of the common carp, Cyprinus carpio. In this study, the effects of sesamin on renal oxidative stress and apoptosis in fluoride-exposed fish were determined. The results showed that sesamin alleviated significantly fluoride-induced renal damage and apoptosis of carp in a dose-dependent manner, indicated by the histopathological examination and ultrastructural observation. Moreover, treatment with sesamin also inhibited significantly fluoride-induced remarkable enhancement of reactive oxygen species (ROS) production and oxidative stress, such as the increase of lipid peroxidation level and the depletion of intracellular reduced glutathione (GSH) level in kidney. To explore the underlying mechanisms of sesamin action, we found that activities of caspase-3 were notably inhibited by treatment with sesamin in the kidney of fluoride-exposed fish. Sesamin decreased the levels of p-JNK protein in kidney, which in turn inactivated pro-apoptotic signaling events by restoring the balance between mitochondrial pro- and anti-apoptotic Bcl-2 and Bax proteins and by decreasing the release of mitochondrial cytochrome c in kidney of fluoride-exposed fish. JNK was also involved in the mitochondrial extrinsic apoptotic pathways of sesamin effects against fluoride-induced renal injury by regulating the levels of p-c-Jun, necrosis factor-alpha (TNF-α) and Bak proteins. These findings indicated that sesamin could protect kidney against fluoride-induced apoptosis by the oxidative stress downstream-mediated change in the inactivation of JNK signaling pathway. Taken together, sesamin plays an important role in maintaining renal health and preventing kidney from toxic damage induced by fluoride.

Abstract
Oxidative stress-induced neuronal death has an important role in the pathogenesis of neurodegenerative disorders. The effects and mechanisms of action of the total flavonoids (TFs) from Rosa laevigata Michx fruit against hydrogen peroxide (H2O2)-induced oxidative injury in PC12 cells were investigated in this study. The results demonstrated that the TFs protected against cell apoptosis, DNA and mitochondrial damage caused by H2O2 based on single cell gel electrophoresis, in situ terminal deoxynucleotidyltransferase dUTP nick end labeling (TUNEL), flow cytometry and transmission electron microscope (TEM) assays. In addition, the TFs notably decreased cytochrome C release from mitochondria into the cytosol and intracellular Ca2+ levels, and diminished intracellular generation of reactive oxygen species (ROS). Furthermore, the TFs inhibited the phosphorylation levels of JNK, ERK and p38 MAPK as well as down-regulated the expressions of IL-1, IL-6, TNF-α, Fas, FasL, CYP2E1, Bak, caspase-3, caspase-9, p53, COX-2, NF-κB, AP-1, and up-regulated the expressions of Bcl-2 and Bcl-xl. In conclusion, these results suggest that the TFs from R. laevigata Michx fruit show good effects against H2O2-induced oxidative injury in PC12 cells by adjusting oxidative stress, and suppression of apoptosis and inflammation, and could be developed as a potential candidate to prevent oxidative stress in the future.

Effects of the total saponins from Rosa laevigata Michx fruit against acetaminophen-induced liver damage in mice via induction of autophagy and suppression of inflammation and apoptosis. Molecules 2014; 19:7189-206.

Abstract
The effect of the total saponins from Rosalaevigata Michx fruit (RLTS) against acetaminophen (APAP)-induced liver damage in mice was evaluated in the present paper. The results showed that RLTS markedly improved the levels of liver SOD, CAT, GSH, GSH-Px, MDA, NO and iNOS, and the activities of serum ALT and AST caused by APAP. Further research confirmed that RLTS prevented fragmentation of DNA and mitochondrial ultrastructural alterations based on TdT-mediated dUTP nick end labeling (TUNEL) and transmission electron microscopy (TEM) assays. In addition, RLTS decreased the gene or protein expressions of cytochrome P450 (CYP2E1), pro-inflammatory mediators (IL-1β, IL-4, IL-6, TNF-α, iNOS, Bax, HMGB-1 and COX-2), pro-inflammatory transcription factors (NF-κB and AP-1), pro-apoptotic proteins (cytochrome C, p53, caspase-3, caspase-9, p-JNK, p-p38 and p-ERK), and increased the protein expressions of Bcl-2 and Bcl-xL. Moreover, the gene expression of IL-10, and the proteins including LC3, Beclin-1 and Atg5 induced by APAP were even more augmented by the extract. These results demonstrate that RLTS has hepatoprotective effects through antioxidative action, induction of autophagy, and suppression of inflammation and apoptosis, and could be developed as a potential candidate to treat APAP-induced liver damage in the future.

Abstract
Tetrachlorobenzoquinone (TCBQ) is an active metabolite of pentachlorophenol (PCP). Although PCP has been investigated extensively, there are only a few reports describing the toxicity effect of TCBQ, and no report regarding TCBQ-induced liver injury in vivo. In the current study, we aimed to examine the acute hepatic toxicity of TCBQ in the mice model. Chlorogenic acid (CGA) exhibits promising antioxidant activity in the past studies, thus, the second aim of this study was to evaluate the protective effect of CGA on TCBQ-induced liver injury. Our results indicated TCBQ-intoxication caused marked liver cell necrosis and inflammation but not apoptosis, and this damage was alleviated by CGA treatment. Meantime, TCBQ-intoxication enhanced serum ALT, AST activities, TBIL content, hepatic oxidative stress and lipid peroxidation, decreased GSH content and inhibited the activities of antioxidant enzymes. Western blot and immunohistochemical analysis showed that TCBQ marked up-regulated HO-1 and NQO1 expression. On the other hand, pretreatment of CGA reduced TCBQ-induced liver damage remarkably. Taking together, these results revealed that TCBQ has strong hepatic toxic effect, and at least a part of this effect is initiated by free radical and relieved with CGA administration.

Abstract
The phenolic composition of the free phenolic extract from Sphallerocarpus gracilis seeds was analyzed by HPLC-MS and predominant compounds were chlorogenic acid, di-caffeoylquinic acid glucoside and luteolin-7-O-glucoside. The free phenolic extract was evaluated for DNA damage protective activity induced by ROO and OH radicals and hepatoprotective effect in vivo and in vitro. Results revealed that the free phenolic extract exhibited significant protective activity against both ROO and OH radical-induced DNA damage and the phenolic extract exerted more potent inhibitory activity against OH radical-induced damage than against that induced by ROO radicals. In vivo experimental results showed that the phenolic extract significantly prevented the increase of serum alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase activities and hepatic malondialdehyde level caused by CCl4 in rats, and markedly increased hepatic superoxide dismutase, catalase and glutathione peroxidase levels. Histopathological examinations further confirmed that the phenolic extract could protect the liver from CCl4-induced damage. In vitro experimental results showed that the phenolic extract could reduce BRL hepatocyte apoptosis and damage induced by CCl4. These findings indicate that the S. gracilis seed could be developed as a medicinal herb for the therapy and prevention of hepatic injury.

Antioxidant activity of extract and its major constituents from okra seed on rat hepatocytes injured by carbon tetrachloride. BIOMED RESEARCH INTERNATIONAL 2014; 2014:341291.

Abstract
The antioxidant activities and protective effects of total phenolic extracts (TPE) and their major components from okra seeds on oxidative stress induced by carbon tetrachloride (CCl4) in rat hepatocyte cell line were investigated. The major phenolic compounds were identified as quercetin 3-O-glucosyl (1 → 6) glucoside (QDG) and quercetin 3-O-glucoside (QG). TPE, QG, and QDG from okra seeds exhibited excellent reducing power and free radical scavenging capabilities including α, α-diphenyl-β-picrylhydrazyl (DPPH), superoxide anions, and hydroxyl radical. Overall, DPPH radical scavenging activity and reducing power of QG and QDG were higher than those of TPE while superoxide and hydroxyl radical scavenging activities of QG and TPE were higher than those of QDG. Furthermore, TPE, QG, and QDG pretreatments significantly alleviated the cytotoxicity of CCl4 on rat hepatocytes, with attenuated lipid peroxidation, increased SOD and CAT activities, and decreased GPT and GOT activities. The protective effects of TPE and QG on rat hepatocytes were stronger than those of QDG. However, the cytotoxicity of CCl4 on rat hepatocytes was not affected by TPE, QG, and QDG posttreatments. It was suggested that the protective effects of TPE, QG, and QDG on rat hepatocyte against oxidative stress were related to the direct antioxidant capabilities and the induced antioxidant enzymes activities.

Hepatoprotective properties of sesamin against CCl4 induced oxidative stress-mediated apoptosis in mice via JNK pathway. Food Chem Toxicol 2013; 64:41-8.

Abstract
Sesamin (Ses), one of the major lignan derived from sesame seeds, has been reported to have many benefits and medicinal properties. However, its protective effects against carbon tetrachloride (CCl4) induced injury in liver have not been clarified. The aim of the present study was to investigate the hepatoprotective effects of sesamin on oxidative stress and apoptosis in mice exposed to CCl4. Our data showed that sesamin significantly prevented CCl4-induced hepatotoxicity in a dose-dependent manner, indicated by both diagnostic indicators of liver damage (serum aminotransferase activities) and histopathological analysis. Moreover, CCl4-induced profound elevation of reactive oxygen species (ROS) production and oxidative stress, as evidenced by increasing of lipid peroxidation level and depleting of the total antioxidant capacity (TAC) in liver, were suppressed by treatment with sesamin. Furthermore, TUNEL assay showed that CCl4-induced apoptosis in mouse liver was significantly inhibited by sesamin. In exploring the underlying mechanisms of sesamin action, we found that activities of caspase-3 were markedly inhibited by the treatment of sesamin in the liver of CCl4 treated mice. Sesamin increased expression levels of phosphorylated Jun N-terminal kinases (JNK) in liver, which in turn inactivated pro-apoptotic signaling events restoring the balance between mitochondrial pro- and anti-apoptotic Bcl-2 proteins and decreasing the release of mitochondrial cytochrome c in liver of CCl4 treated mice. JNK was also involved in the mitochondrial extrinsic apoptotic pathways of sesamin effects against CCl4 induced liver injury by regulating the expression levels of phosphorylated c-Jun proteins, necrosis factor-alpha (TNF-α) and Bak. In conclusion, these results suggested that the inhibition of CCl4-induced apoptosis by sesamin is due at least in part to its anti-oxidant activity and its ability to modulate the JNK signaling pathway.

Abstract
The effects and mechanisms of the total flavonoids (TFs) from Rosa laevigata Michx fruit on high-fat diet-induced non-alcoholic fatty liver disease (NAFLD) were investigated in this study. Gavage administration of the TFs significantly decreased the relative liver weight, serum AST and ALT activities, the levels of serum lipid, LDL, blood glucose and insulin, suppressed lipid accumulation in liver, and increased serum HDL level. Moreover, the natural product significantly enhanced SOD activity, increased GSH-Px and GSH contents and decreased the concentration of MDA and CYP2E1 expression as well as prevented mitochondrial membrane potential dysfunctions and ultrastructural alterations. Further mechanism investigation indicated that the TFs inhibited hepatic lipid accumulation by suppressing the expressions of some key molecules in fatty acid synthesis pathway and promoting fatty acid β-oxidation, while not by inhibiting cholesterol synthesis. On the base of these, the TFs should be developed as a new drug for treatment of NAFLD.
