RESUMO
ETHNOPHARMACOLOGICAL RELEVANCE: Cholic acid (CA) is one of the main active ingredients in Calculus Bovis, a traditional Chinese medicine, which helps to regulate the heart and liver meridians, clearing the heart, opening the mouth, cooling the liver and calming the wind. However, the molecular mechanism of its liver protective effect is still unclear. AIM OF THE STUDY: Growing attention has been directed towards traditional Chinese medicine (TCM), particularly Calculus Bovis, as a potential solution for liver protection. Despite this interest, a comprehensive understanding of its hepatoprotective mechanisms remains lacking. This research seeks to explore the potential protective properties of cholic acid (CA) against CCl4-induced acute liver injury (ALI) in mice, while also examining the mechanisms involved. MATERIALS AND METHODS: In the experiment, a mouse model was employed to ALI using CCl4, and the potential therapeutic effects of orally administered CA at varying doses (15, 30, and 60 mg/kg) were assessed. The study employed a multi-faceted approach, integrating liver transcriptomics with serum metabolomics, and conducting thorough analyses of serum biochemical markers and liver histopathological sections. RESULTS: Oral CA administration markedly reduced the organ indices of the liver, spleen, and thymus in comparison with the model group. It also elevated the expression of superoxide dismutase (SOD) in serum while diminishing the concentrations of ALT, AST, MDA, IL-6, and TNF-α. Moreover, CA ameliorated the pathological damage induced by CCl4. Integrated metabolomic and transcriptomic analyses indicated that the hepatoprotective action of CA on ALI is mediated through the modulation of lipid metabolic pathways-specifically, metabolisms of glycerophospholipid, arachidonic acid, as well as linoleic acid-and by altering the expression of genes such as Ptgr1, PLpp1, Tbxas1, and Cyp2c37. CONCLUSIONS: The current investigation offers insights into the hepatoprotective mechanisms by which CA mitigates ALI caused by CCl4 exposure, thus supporting the further evaluation and development of CA-based therapeutics for ALI.

ETHNOPHARMACOLOGICAL RELEVANCE: Liver fibrosis (LF) is a common reversible consequence of chronic liver damage with limited therapeutic options. Yinchen Gongying decoction (YGD) composed of two homologous plants: (Artemisia capillaris Thunb, Taraxacum monochlamydeum Hand.-Mazz.), has a traditionally application as a medicinal diet for acute icteric hepatitis. However, its impact on LF and underlying mechanisms remain unclear. AIM OF THE STUDY: This study aims to assess the impact of YGD on a carbon tetrachloride (CCl4) induced liver fibrosis and elucidate its possible mechanisms. The study seeks to establish an experimental foundation for YGD as a candidate drug for hepatic fibrosis. MATERIALS AND METHODS: LC-MS/MS identified 11 blood-entry components in YGD, and network pharmacology predicted their involvement in the FoxO signaling pathway, insulin resistance, and PI3K-AKT signaling pathway. Using a CCl4-induced LF mouse model, YGD's protective effects were evaluated in comparison to a positive control and a normal group. The underlying mechanisms were explored through the assessments of hepatic stellate cells (HSCs) activation, fibrotic signaling, and inflammation. RESULTS: YGD treatment significantly improved liver function, enhanced liver morphology, and reduced liver collagen deposition in CCl4-induced LF mice. Mechanistically, YGD inhibited HSC activation, elevated MMPs/TIMP1 ratios, suppressed the FoxO1/TGF-ß1/Smad2/3 and YAP pathways, and exhibited anti-inflammatory and antioxidant effects. Notably, YGD improved the insulin signaling pathway. CONCLUSION: YGD mitigates LF in mice by modulating fibrotic and inflammatory pathways, enhancing antioxidant responses, and specifically inhibiting FoxO1/TGF-ß1/Smad2/3 and YAP signal pathways.

ETHNOPHARMACOLOGICAL RELEVANCE: Liver fibrosis is a serious complication of liver disease characterized by excessive collagen deposition, without effective therapeutic agents in the clinic. Fu-Gan-Wan (FGW) is an empirical formula used for the clinical treatment of hepatitis and cirrhosis. It has been shown to reverse experimental liver fibrosis. However, its corresponding mechanisms remain unclear. AIM OF THE REVIEW: This study aimed to elucidate the key pathways and target genes of FGW in attenuating liver fibrosis. MATERIALS AND METHODS: The therapeutic effects of different doses of FGW on liver fibrosis were investigated using a 2 mL/kg 15% CCl4-induced mouse model. Then, RNA-seq combined with network pharmacology was used to analyze the key biological processes and signaling pathways underlying the anti-liver fibrosis exertion of FGW. These findings were validated in a TGF-ß1-induced model of activation and proliferation of mouse hepatic stellate cell line JS-1. Finally, the key signaling pathways and molecular targets were validated using animal tissues, and the effect of FGW on tissue lipid peroxidation was additionally observed. RESULTS: We found that 19.5 g/kg FGW significantly down-regulated CCl4-induced elevation of hepatic ALT and AST, decreased collagen deposition, and inhibited the expression of pro-fibrotic factors α-SMA, COL1α1, CTGF, TIMP-1, as well as pro-inflammatory factor TGF-ß1. Additionally, FGW at doses of 62.5, 125, and 250 µg/mL dose-dependently blocked JS-1 proliferation, migration, and activation. Furthermore, RNA-seq identified the NF-κB signaling pathway as a key target molecular pathway for FGW against liver fibrosis, and network pharmacology combined with RNA-seq focused on 11 key genes. Significant changes were identified in CCL2 and HMOX1 by tissue RT-PCR, Western blot, and immunohistochemistry. We further demonstrated that FGW significantly attenuated CCl4-induced increases in p-p65, CCL2, CCR2, and HMOX1, while significantly elevating Nrf2. Finally, FGW significantly suppressed the accumulation of lipid peroxidation products MDA and 4-HNE and reconfigured the oxidation-reduction balance, including promoting the increase of antioxidants GPx, GSH, and SOD, and the decrease of peroxidation products ROS and GSSG. CONCLUSIONS: This study demonstrated that FGW exhibits potential in mitigating CCl4-induced hepatic fibrosis, lipid peroxidation, and iron metabolism disorders in mice. This effect may be mediated through the NF-κB/CCL2/CCR2 and Nrf2/HMOX1 pathways.

ETHNOPHARMACOLOGICAL RELEVANCE: In the progression of chronic liver diseases, liver fibrosis is a reversible pathophysiologic event for liver diseases prognosis and risk of cirrhosis. Liver injury factors of different etiologies mediate this process. There is still a lack of effective medications for treating liver fibrosis. Additionally, the ameliorative effects of traditional herbs on liver fibrosis have been commonly reported. Tianhuang formula (THF) is a drug combination consisting of 2 traditional Chinese herbs, which has been showing significant improvement in metabolic liver diseases. However, the hepatoprotective effect and mechanism of THF in ameliorating liver fibrosis are still unclear. AIM OF THE STUDY: This study aimed to investigate the effects of THF on carbon tetrachloride (CCl4)-induced and methionine-choline-deficient (MCD) diet-induced liver fibrosis model and to reveal the potential mechanisms. It can provide experimental evidence for THF as a therapeutic candidate for liver fibrosis. MATERIALS AND METHODS: In this study, CCl4-induced mice were treated with THF (80 mg/kg, 160 mg/kg) or Fuzheng Huayu (FZHY) capsules (4.8 g/kg) for 6 weeks. MCD-induced mice received the same doses of THF or FZHY for 4 weeks. FZHY is used as a comparative study in these two models. Following that, using kit reagents detected changes in relevant serum and liver biochemical indicators. Histological changes in mouse liver were measured by staining of H&E and Sirius Red. The markers expression of liver fibrosis and inflammation were detected using qRT-PCR, western blotting and immunohistochemical staining analysis. The potential regulatory mechanism of THF to ameliorate liver fibrosis was performed by RNA-sequencing analysis. Finally, the analysis results were verified by immunofluorescence co-staining, qRT-PCR and western blotting. RESULTS: Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and hepatic triglyceride (TG) levels in CCl4 and MCD-induced liver fibrosis mice were significantly improved after THF treatment. Meanwhile, the expression of fibrosis and inflammation markers were significantly suppressed. Furthermore, THF downregulated the expression of the macrophage marker CD68. According to RNA-sequencing analysis, we found the CCL2-CCR2 axis and MAPK/NF-κB as the potential signaling pathway for THF against liver fibrosis. CONCLUSION: This study revealed that THF ameliorated liver injury, inflammation and fibrotic process by inhibiting CCL2-CCR2 axis and its downstream MAPK/NF-κB signaling pathway.

ETHNOPHARMACOLOGICAL RELEVANCE: Qijia Rougan decoction (QJ), consisting of eight herbs and two animal drugs, is an effective traditional Chinese medicine with hepatoprotective and antifibrotic effects. However, its underlying action mechanism remains unclear. AIM OF THE STUDY: To explore the mechanism underlying the treatment of liver fibrosis in rats by QJ. MATERIALS AND METHODS: Rats with fibrosis were constructed using carbon tetrachloride (CCl4). The QJ was orally administered to fibrotic rats. Hepatic pathological changes were evaluated using hematoxylin and eosin and Masson's trichrome staining. The differentially expressed proteins (DEPs) in QJ were analyzed using quantitative proteomics. Subsequently, the underlying mechanisms in liver fibrosis after QJ treatment were validated using Western blotting. RESULTS: The QJ markedly improved liver function and attenuated fibrotic progression. Based on the tandem mass-tag based (TMT) proteomics, we identified 818 common DEPs between QJ vs Model and Model vs Control, including 296 upregulated and 522 downregulated DEPs, which mostly participate in metabolic pathways, oxidation-reduction reactions, and collagen biosynthetic processes. In addition, we found that QJ reduced hepatocellular death by inhibiting the expression of caspase proteins, repressing pro-apoptotic proteins, and promoting anti-apoptotic proteins. We further demonstrated that QJ suppressed the Akt/mTOR pathway. CONCLUSION: QJ exerted hepatoprotective effects in CCl4-induced rats through multi-pathway regulation. This study provides protein information on liver fibrosis treated with QJ.

OBJECTIVES: The hepatoprotective properties of scopoletin have been explored in carbon tetrachloride (CCl4) induced liver injury but not in drug-induced liver injury (DILI) scenarios. Only N-acetyl-cysteine (NAC) has proven efficacy in DILI treatment. Accordingly, we conducted a study to assess the hepatoprotective action of scopoletin in the anti-tubercular treatment (ATT)-DILI model in Wistar rats, if any. METHODS: A total of 36 rats were evaluated, with six in each group. A 36-day ATT at 100â¯mg/kg dose for isoniazid, 300â¯mg/kg for rifampicin and 700â¯mg/kg for pyrazinamide were fed to induce hepatotoxicity in rats. Group I and II-VI received normal saline and ATT, respectively. Oral scopoletin (1,5 and 10â¯mg/kg) and NAC 150â¯mg/kg were administered in groups III, IV, V and VI, respectively, once daily for the last 15 days of the experiment. LFT monitoring was performed at baseline, days 21, 28, and 36. Rats were sacrificed for the histopathology examination. RESULTS: Aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP) and bilirubin levels were significantly increased in group II (receiving ATT) compared to normal control on day 28 and day 36 (p<0.05). All three doses of scopoletin and NAC groups led to the resolution of AST, ALT, ALP, and bilirubin changes induced by ATT medications effect beginning by day 28 and persisting on day 36 (p<0.01). An insignificant effect was observed on albumin and total protein levels. The effect was confirmed with antioxidants and histopathology analysis. CONCLUSIONS: The study confirms the hepatoprotective efficacy of scopoletin in a more robust commonly encountered liver injury etiology.

Liver injury can be acute or chronic, resulting from a variety of factors, including viral hepatitis, drug overdose, idiosyncratic drug reaction, or toxins, while the progression of pathogenesis in the liver rises due to the involvement of numerous cytokines and growth factor mediators. Thus, the identification of more effective biomarker-based active phytochemicals isolated from medicinal plants is a promising strategy to protect against CCl4-induced liver injury. Vitis vinifera L. (VE) and Centella asiatica (CE) are well-known medicinal plants that possess anti-inflammatory and antioxidant properties. However, synergism between the two has not previously been studied. Here, we investigated the synergistic effects of a V. vinifera L. (VE) leaf, C. asiatica (CE) extract combination (VCEC) against CCl4-induced liver injury. Acute liver injury was induced by a single intraperitoneal administration of CCl4 (1 mL/kg). VCEC was administered orally for three consecutive days at various concentrations (100 and 200 mg/kg) prior to CCl4 injection. The extent of liver injury and the protective effects of VCEC were evaluated by biochemical analysis and histopathological studies. Oxidative stress was evaluated by measuring malondialdehyde (MDA) and glutathione (GSH) levels and Western blotting. VCEC treatment significantly reduced serum transaminase levels (AST and ALT), tumor necrosis factor-α (TNF-α), and reactive oxygen species (ROS). CCl4- induced apoptosis was inhibited by VCEC treatment by reducing cleaved caspase-3 and Bcl2-associated X protein (Bax). VCEC-treated mice significantly restored cytochrome P450 2E1, nuclear factor erythroid 2-related factor 2 (Nrf2), and heme oxygenase-1 (HO-1) expression in CCl4-treated mice. In addition, VCEC downregulated overexpression of proinflammatory cytokines and hepatic nuclear factor kappa B (NF-κB) and inhibited CCl4-mediated apoptosis. Collectively, VCEC exhibited synergistic protective effects against liver injury through its antioxidant, anti-inflammatory, and antiapoptotic ability against oxidative stress, inflammation, and apoptosis. Therefore, VCEC appears promising as a potential therapeutic agent for CCl4-induced acute liver injury in mice.

An in vitro/in vivo hepatotoxicity and hepatoprotection evaluation of a defatted extract and a phenolic fraction from Phlomis tuberosa, administered alone and in a carbon tetrachloride (CCl4)-induced metabolic bioactivation model, was performed. The extract and the phenolic fraction were analysed by high performance liquid chromatography (HPLC) to determine the total flavonoid content, to identify flavonoids and to quantify verbascoside. In addition, total polyphenolics in the samples were expressed as gallic acid equivalents. Applied alone, the extract and the fraction (5, 10 and 50 µg/mL) did not show a statistically significant hepatotoxic effect on isolated rat hepatocytes in vitro. In a CCl4-induced hepatotoxicity model, the samples exhibited a concentration-dependent, statistically significant hepatoprotective effect, which was most pronounced at 50 µg/mL for both. The phenolic fraction exhibited a more pronounced hepatoprotective effect compared to the extract. Data from the in vitro study on the effects of the extract were also confirmed in the in vivo experiment conducted in a CCl4-induced hepatotoxicity model in rats. A histopathological study showed that the animals treated with CCl4 and the extract had an unaltered histoarchitecture of the liver. The effects of the extract were the same as those of silymarin.

Carthamus tinctorius L. leaves, a waste product after Carthami flos production, are rich in flavonoids. Total flavonoids from C. tinctorius L. leaves (TFCTLL) exhibited the protective effect on acute liver injury in mice in previous studies. The aim of the present study was to evaluate the hepatoprotective effect of TFCTLL on chronic liver injury (CLI) and investigate the underlying mechanism. The chemical components of TFCTLL were identified by UPLC-Q-TOF/MS, and their migration into blood was evaluated. The protective effect of TFCTLL on CLI was evaluated by antioxidative and anti-inflammatory experiments in vitro, network pharmacology and a carbon tetrachloride (CCl4)-induced CLI mouse model. We indentified 18 chemical components in the TFCTLL samples and 4 components in plasma. TFCTLL showed significant anti-inflammatory activity and antioxidant capacity in vitro and in vivo. TFCTLL administration prominently improved the liver function and structure, decreased the mRNA expression levels of TLR2, TLR3, TLR4, NF-κB p65, IRF3, AKT1, TRIF, PI3K, MyD88, IL-1ß and TNF-α and inhibited the protein expression and nuclear translocation of NF-κB p65 in mice with CLI. The molecular docking results showed that components in plasma had high binding affinity for the targets TLR4, PI3K and AKT1. Therefore, TFCTLL has a protective effect against CCl4-induced CLI, and the underlying mechanisms may be related to antioxidation, anti-inflammation and modulation of the TLRs/NF-κB and PI3K/AKT pathways.

ETHNOPHARMACOLOGICAL RELEVANCE: Fuzheng Huayu formula (FZHY), composed of Salvia miltiorrhiza Bunge, Cordyceps sinensis, the seed of Prunus persica (L.) Batsch, the pollen of Pinus massoniana Lamb, Gynostemma pentaphyllum (Thunb.) Makino and the fruit of Schisandra chinensis (Turcz.) Baill, is a Chinese herbal compound with demonstrated clinical benefits in liver fibrosis (LF). However, its potential mechanism and molecular targets remain to be elucidated. AIM OF THE STUDY: This study was designed to evaluate the anti-fibrotic role of FZHY in hepatic fibrosis and to elucidate the potential mechanisms. MATERIALS AND METHODS: Network pharmacology was assayed to identify the interrelationships among compounds of FZHY, potential targets and putative pathways on anti-LF. Then the core pharmaceutical target for FZHY against LF was verified by serum proteomic analysis. Further in vivo and in vitro assays were performed to verify the prediction of the pharmaceutical network. RESULTS: The network pharmacology analysis revealed that a total of 175 FZHY-LF crossover proteins were filtered into a protein-protein interaction (PPI) network complex and designated as the potential targets of FZHY against LF, and the Epidermal Growth Factor Receptor (EGFR) signaling pathway was further explored according to the Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. Then analytical studies were validated by carbon tetrachloride (CCl4)-induced model in vivo. We found FZHY could attenuate CCl4-induced LF, especially decrease p-EGFR expression in α-Smooth Muscle Actin (α-SMA)-positive hepatic stellate cell (HSC) and inhibit the downstream of the EGFR signaling pathway, especially Extracellular Regulated Protein Kinases (ERK) signaling pathway in liver tissue. We further demonstrate that FZHY could inhibit Epidermal Growth Factor (EGF)-induced HSC activation, as well as the expression of p-EGFR and the key protein of the ERK signaling pathway. CONCLUSIONS: FZHY has a good effect against CCl4-induced LF. The action mechanism was associated with the down-regulation of the EGFR signaling pathway in activated HSCs.

ETHNOPHARMACOLOGICAL RELEVANCE: Jiawei Taohe Chengqi Decoction (JTCD) is a Traditional Chinese Medicine (TCM) formula modified from Taohe Chengqi Decoction in the classic ancient literature of TCM "Treatise on Febrile Diseases". Clinical and pharmacological studies have shown that JTCD has a therapeutic effect on hepatic encephalopathy, non-alcoholic fatty liver, cirrhotic ascites, and can alleviate acute liver injury in rats. Our previous studies confirmed that JTCD could alleviate hepatic fibrosis and activation of hepatic stellate cells (HSCs). However, its mechanism remains unclear. AIM OF THE STUDY: This study aimed to elucidate the mechanism of Src Signal on hepatic fibrosis and HSCs activation, and whether JTCD inhibited hepatic fibrosis and HSCs activation through affecting Src Signal. MATERIALS AND METHODS: In vivo, sixty specific pathogen free male C57/BL6 mice were divided into following six groups: Control group, Model group, SARA group, JTCD low dose group, JTCD medium dose group and JTCD high dose group. Then we established a carbon tetrachloride (CCL4)-induced hepatic fibrosis mice model, each JTCD group was given the corresponding dose of JTCD by gavage, the SARA group was given Saracatinib and the control group was given saline, once a day for 4 consecutive weeks. UPLC-Q-TOF-MS analyzed chemical components of JTCD. Pathological examination including Hematoxylin and Eosin (H&E), Masson and Sirius red staining was used to observe the characteristic of hepatic fibrosis. Automatic biochemical analyzer detected the levels of alanine aminotransfease (ALT), and aspartate transaminase (AST) in serum. Western-blot and immunohistochemical staining (IHC) detected protein expression. In vitro, we used shRNA to knock down the expression of Src in immortalized human hepatic stellate cell line (LX-2), then intervened with ERK1/2 agonists/inhibitors and JTCD-containing serum after transforming growth factor ß1 (TGF-ß1) treatment. Immunofluorescence and western-blot detected protein expression. The migratory characteristic of HSCs was assessed by wound-healing assay. RESULTS: We identified 135 chemical components in the water extract of JTCD, and the water extract of JTCD contains a variety of anti-hepatic fibrosis components. Compared to the model group, hepatic fibrosis performance was significantly improved, the serum levels of ALT and AST were significantly decreased in JTCD groups and SARA group, IHC staining and western blot results indicated that JTCD decreased the expressions of α-smooth muscle actin (α-SMA), phospho-Src (Tyr416), phospho-ERK1/2 and phospho-Smad3. In vitro, JTCD-containing serum could significantly decrease the protein expressions of α-SMA, phospho-Src (Tyr416), phospho-ERK1/2 and phospho-Smad3 according to the results of western-blot and immunofluorescence, in addition, JTCD-containing serum inhibited the mobility and activation of LX-2. What's more, after intervening with Src-shRNA, ERK1/2 agonists/inhibitors and JTCD-containing serum, the western-blot results showed that Src/ERK/Smad3 signal has an important role in hepatic fibrosis and HSCs, and JTCD attenuates hepatic fibrosis by preventing activation of HSCs through regulating Src/ERK/Smad3 signal pathway. CONCLUSIONS: The results showed that Src kinase promoted hepatic fibrosis and HSCs activation through the ERK/Smad3 signal pathway. More importantly, the mechanism by which JTCD attenuated hepatic fibrosis and HSCs activation was by inhibiting the Src/ERK/Smad3 signal pathway.

ETHNOPHARMACOLOGICAL RELEVANCE: Arnebia euchroma (Royle) I.M.Johnst. (AE) is a Chinese medicinal herb that is traditionally used to treat various circulatory diseases. It exhibits certain effects, such as the promotion of blood circulation and cooling, rash clearance, and detoxification. AIM OF THE STUDY: This study was designed to explore the hepatoprotective and hemostatic effects of the ethyl acetate extract of AE in rats with carbon tetrachloride (CCl4)-induced liver injury. MATERIALS AND METHODS: Wistar rats were treated via oral gavage with different doses of the ethyl acetate extract of AE (3.5, 7, or 14 g kg-1·day-1) for 14 consecutive days, following which hemostatic and liver function tests were conducted. For the hemostatic tests, the platelet count, blood platelet aggregation, blood platelet adhesion to fibrinogen, platelet factor 4 (PF-4) secretion from blood platelets, prothrombin time (PT), activated partial thromboplastin time (aPTT), thrombin time (TT), and fibrinogen levels were measured at the end of the treatment period. For the liver function tests, 0.25 mL/200 g (1.25 mL kg-1·day-1) of olive oil was injected into the abdominal cavity of the control rats, whereas 15% CCl4 plus olive oil (prescription: 7.5 mL CCl4 + 42.5 olive oil) was injected into that of the treated rats at 1 h after extract administration on day 6, 13, and 20. Additionally, food and water were withheld from all the animals. On the following day, the rats were anesthetized and their albumin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT), gamma-glutamyl transpeptidase (GGT), lactate dehydrogenase (LDH), reactive oxygen species (ROS), methane dicarboxylic aldehyde (MDA), superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH) levels were measured. Glutathione S-transferase (GST), glutathione reductase (GR), and glutathione peroxidase (GPx) levels among the groups were determined using a one-way analysis of variance. RESULTS: The platelet count and blood platelet aggregation, blood platelet adhesion to fibrinogen and PF-4 secretion levels were significantly increased in the (3.5 g kg-1 day-1) AE group as compared to those in the control group (all p < 0.001; for the 7 and 14 g kg-1 day-1 AE groups, all p > 0.05, respectively). Although the PT and aPTT were not affected by the AE extract (all p > 0.05), the TT was reduced and the FIB levels were significantly increased in all AE groups (p < 0.05). Liver function tests showed that CCl4 caused significant liver damage, thereby decreasing the albumin, SOD, CAT, GSH, GST, GR, and GPx levels, while increasing the AST, ALT, ALP, SGOT, SGPT, GGT, LDH, ROS, and MDA levels (all p < 0.001). By contrast, treatment with the different doses of AE extract reversed the CCl4 effects on all these parameters. Compared with the levels in the CCl4 group, the GSH and GR levels in the three AE groups (3.5, 7, and 14 g kg-1·day-1) were significantly higher (p < 0.05, p < 0.01, and p < 0.001, respectively), whereas the differences in the other parameters for these three groups were all at the significance levels of p < 0.05, p < 0.05, and p < 0.01, respectively. CONCLUSIONS: AE extracts administered orally exhibited hepatoprotective activity by affecting platelet production and blood coagulation and ameliorating liver function-damaging modifications. Specifically, a dosage of 3.5 g kg-1·day-1 resulted in the most optimal effects.

Pien Tze Huang (PZH), a common hepatoprotective Traditional Chinese Medicine that has been found to be an effective treatment for carbon tetrachlorideinduced hepatic damage, including liver fibrosis. Circular RNAs (circRNAs) serve a crucial role in regulating gene expression levels via circRNA/micro (mi)RNA/mRNA networks in several human diseases and biological processes. However, whether circRNAs are involved in the underlying mechanism of the therapeutic effects of PZH on liver fibrosis remains unclear. Therefore, the aim of the present study was to investigate these effects using circRNA expression profiles from PZHtreated fibrotic livers in model mice. A casecontrol study on >59,476 circRNAs from CCl4induced (control group, n=6) and PZHtreated (case group, n=6) mice was performed using circRNA sequencing in liver tissues. PZH treatment resulted in the differential expression of 91 circRNAs, including 58 upregulated and 33 downregulated circRNAs. Furthermore, the construction of competing endogenous networks also indicated that differentially expressed circRNAs acted as miRNA sponges. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis of miRNA targets demonstrated that PZHaffected circRNAs were mainly involved in biological processes such as 'positive regulation of fibroblast proliferation', 'cellular response to interleukin1' and 'regulation of DNAtemplated transcription in response to stress' and in a number of important pathways, such as 'TNF signaling pathway', 'PI3KAkt signaling pathway', 'IL17 signaling pathway' and 'MAPK signaling pathway'. To further validate the bioinformatics data, reverse transcription-quantitative PCR was performed on seven miRNA targets in a human hepatic stellate LX2 cell model. The results suggested that seven of the miRNAs exhibited regulatory patterns that were consistent with those of the transcriptome sequencing results. KaplanMeier survival analysis demonstrated that the expression levels of dihydrodiol dehydrogenase and solute carrier family 7, member 11 gene were significantly associated with patient survival, 269 patients with liver hepatocellular carcinoma from The Cancer Genome Atlas database. To the best of our knowledge, this was the first study to provide evidence that PZH affects circRNA expression levels, which may serve important roles in PZHtreated fibrotic liver through the regulation of functional gene expression. In conclusion, the present study provided new insights into the mechanism underlying the pathogenesis of liver fibrosis and identified potential novel, efficient, therapeutic targets against liver injury.

ETHNOPHARMACOLOGICAL RELEVANCE: Forsythiae fructus, the dried fruit of Oleaceae plant Forsythia suspensa (Thunb.) Vahl, is a traditional Chinese medicine widely used in clinical practice and has a variety of pharmacological activities, such as anti-inflammation, antioxidation, and hepatoprotection. AIM OF THE STUDY: Phillygenin (PHI), an important fingerprint lignan component of Forsythiae fructus, has prominent hepatoprotective, anti-inflammatory and antioxidant effects. Previously, it was shown that PHI could exert anti-fibrotic effects by modulating inflammation and gut microbiota. Therefore, given the important roles of SCFAs and BAs in the development of liver fibrosis, as well as their close links with gut microbiota, we aimed to determine the protective effects of PHI on carbon tetrachloride (CCl4)-induced liver fibrosis and its effects on the metabolism of SCFAs and BAs based on metabolomics. MATERIALS AND METHODS: In C57BL/6J mice, liver fibrosis model was established by intraperitoneal injection of olive oil containing 10% CCl4 for 4 weeks. Firstly, the mouse liver tissues were subjected to histological analysis and biochemical index assay to evaluate the protective effect of PHI on CCl4-induced liver fibrosis. Subsequently, the effects of PHI on the metabolism of SCFAs and BAs in CCl4-induced liver fibrosis mice were determined using gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) for metabolomics analysis. Finally, the levels of the closely related proteins and genes were detected by immunohistochemistry and real-time quantitative polymerase chain reaction (RT-qPCR) to explore the underlying mechanisms of the protective effect of PHI on CCl4-induced liver fibrosis. RESULTS: The histological analysis and the determination of relevant biochemical indexes of liver tissues showed that PHI could attenuate CCl4-induced liver fibrosis. The metabolomic analysis on SCFAs showed that PHI could promote SCFA production in the gut of mice with CCl4-induced liver fibrosis, especially acetic acid, propionic acid and butyric acid. It has been reported that the increased production of SCFAs was possibly beneficial to health. The metabolomic analysis on BAs found that PHI could restore the disturbance of BA metabolism in mice with CCl4-induced liver fibrosis. The immunohistochemistry and RT-qPCR results confirmed that PHI could ameliorate intestinal epithelial barrier disruption, and reverse the expression of BA metabolism-related genes in mice with CCl4-induced liver fibrosis. CONCLUSIONS: Promoting the production of SCFAs in the gut and restoring the disturbance of BA metabolism may be the potential mechanisms by which PHI alleviated CCl4-induced liver fibrosis.

Liver fibrosis is a prevalent liver disease that requires rapid and effective treatment prior to its progression to cirrhosis and liver damage. Recently, several reports have investigated the efficacy of phytotherapy using natural herbal extracts rather than synthetic drugs to treat several liver diseases. Policosanol is a herbal extract used to treat patients with cardiovascular. However, its therapeutic effect on liver fibrosis is still unknown. Therefore, the present study aimed to assess the potential antifibrotic effect of policosanol compared to silymarin and the possible underlying molecular mechanisms. Rats were categorized into four groups; negative control group "NCG", the fibrotic group "FG", silymarin treated group "STG", and policosanol treated group "PTG". Serum liver enzymes, oxidative stress markers, angiogenic growth factors, and pro-inflammatory cytokines were measured biochemically. The relative mRNA expressions of liver caspase-3 and alpha-smooth muscle actin (α-SMA) were assessed. Immunohistochemical staining was carried out using anti- α-SMA, and anti-caspase-3 antibodies. Compared to NCG, the FG group demonstrated a significant decrease in the level of serum liver enzymes "GSH, TAC, and SDF. Nevertheless, it demonstrateda significant increase in the level of pro-inflammatory cytokines "Il-6, TNF"; oxidative stress markers "NO, MDA", and angiogenic growth factors "VEGF and PDGF" and the expression of α-SMA, and Caspase-3. Interestingly, the values of these measurements were restored to normal levels in the treated groups, particularly the PTG. In conclusion, our data revealed the beneficial effects of co-administration of policosanol or silymarin on the fibrotic liver rat model and thus could be a promising natural therapeutic drug.

Jasminum grandiflorum L. (JG) is a medicinal plant containing many bioactive ingredients. Herein, we analyzed the effects of four different extracts and two compounds of JG on acute liver injury caused by carbon tetrachloride (CCl4) and underlying molecular mechanisms. 7 weeks old C57BL/6 male mice were used to establish a liver injury model by injecting with 1% CCl4, 10 mL/kg ip. Four different extracts and two compounds of JG were given to mice by gavage for 3 days. Clinical and histological chemistry assays were performed to assess liver injury. Moreover, hepatic oxidative stress and inflammation related markers were determined by immunohistochemistry and western blotting. As a result, JG extracts and two functional components showed different degree of protect effects against CCl4-induced liver injury by the decrease of elevated serum transaminases and liver index, and the attenuation of histopathological changes in mice, among which JG extracted with petroleum ether (PET) had the most significant effect. In addition, PET remarkably alleviated hepatic oxidative stress and inflammation. Further studies revealed that PET significantly inhibited the TNF-α expression, signal pathway expression, NF-κB p65 and inflammatory factors IL-1ß and IL-6 expression in CCl4-induced liver injury mice. Nevertheless, hydroxytyrosol (HT) alleviated liver injury by reducing oxidative stress. Apart from PET extract, other extracts of JG can inhibit cytochrome CYP2E1 expression to protect liver tissue. These findings suggest that the extracts and its components of JG possesses the potential protective effects against CCl4-induced liver injury in mice by exerting antioxidative stress and anti-inflammation.

Liver fibrosis is a chronic and progressive disease with complex pathogenesis related to bile acids (BAs) and gut microbiota. Forsythiaside A (FTA), isolated from the traditional Chinese medicine Forsythiae Fructus (Lian Qiao), is a natural hepatoprotective agent. The purpose of this study was to investigate the protective effect of FTA on carbon tetrachloride (CCl4)-induced liver fibrosis in mice. Liver fibrosis was induced in mice by intraperitoneal injection of 2 mL/kg CCl4 three times a week for 4 weeks. FTA attenuated CCl4-induced liver fibrosis in mice, which was proved by the results of Masson and Sirius red staining, liver hydroxyproline, hyaluronic acid, laminin, type III procollagen, and type IV collagen assays. FTA inhibited hepatic stellate cell activation, and reduced hepatic inflammation and oxidative stress in mice treated with CCl4. What's more, FTA ameliorated CCl4-induced gut dysbiosis, maintained intestinal barrier function, increased the production of short-chain fatty acids (SCFAs), and improved endotoxemia, as manifested by decreased serum lipopolysaccharide levels and increased expression of ileal tight junction proteins. Besides, FTA can modulate the genes related to bile acid metabolism to alter the distribution of fecal BAs in fibrotic mice. In a word, FTA can improve liver fibrosis by inhibiting inflammation and oxidative stress, regulating gut microbiota and BA metabolism, and increasing the content of SCFAs. The results of this study provided an important reference for the study on the mechanisms by which natural products prevent liver fibrosis.

ETHNOPHARMACOLOGICAL RELEVANCE: Honghua Qinggan 13 Flavor Pills (HHQG), whose Mongolian name is Guri Gumu-13, is a traditional Mongolian medicine, that was stated in the "Diagnosis and Treatment of Ming Medical Code". The HHQG has been included in the Mongolian Medicine Division of the Ministry of Health Drug Standards (1998 edition). Based on our clinical expertise, HHQG demonstrated satisfactory therapeutic effects in hepatitis and liver failure. However, the pharmacological effects and potential mechanisms of HHQG have not been investigated. AIM OF THE STUDY: In this study, we combined network pharmacology, transcriptomics, and molecular biology to detect the underlying mechanism for the effect of HHQG on acute liver injury in mice. MATERIALS AND METHODS: Network pharmacology was used to explore the pathways involved in the protective effect HHQG in acute liver injury. This effect was further verified by injecting carbon tetrachloride (CCl4; 10 mL/kg, i.p.) to induce acute liver injury in mice. Serum markers of liver injury, morphology, histology, and monocyte/macrophage infiltration in the liver tissue were investigated. Transcriptomics further defined the HHQG targets. Transwell analysis was performed to confirm that HHQG inhibited monocyte/macrophage RAW.264.7 infiltration. qPCR and Western blot were performed to explore the mechanism of action of HHQG. RESULTS: Network pharmacology showed that HHQG exerted anti-oxidative and anti-inflammatory effects and promoted metabolic effects against acute liver injury. Pretreatment of mice with HHQG significantly maintained their body weight and decreased serum tumor necrosis factor-alpha (TNF-α) levels induced by CCl4 treatment in vivo. Histopathological examination further confirmed that HHQG protected the liver cells from CCl4-induced damage. Importantly, HHQG significantly inhibited CCl4-induced monocyte/macrophage infiltration. Transcriptomic analysis revealed that HHQG significantly reduced the expression of chemokines and cell adhesion molecules. We determined that HHQG significantly downregulated the expression of the key chemokine (monocyte chemokine protein-1, CCL2) at the gene and protein levels. Further research showed that HHQG inhibited chemokine production in hepatocytes by inhibiting the p-P38 and p-JNK pathways, thereby reducing monocyte/macrophage infiltration. CONCLUSIONS: These combined data showed that HHQG alleviated acute liver injury in mice, and further verified that HHQG exerted protective effects by inhibiting the production of CCL2 and reducing the infiltration of monocyte/macrophage by inhibiting the p-P38 and p-JNK pathways.

Liver injury is a major public health problem all over the world that raises the demand of developing novel effective and safe remedies. Traditionally, Thyme (Thymus fontanesii) has a therapeutic potential against different organs toxicity due to its antioxidant activity. The present study aimed to evaluate the antioxidant activities in vitro and the possible hepato-protective effects of T. fontanesii aqueous extract (TFAE) against CCl4 induced liver damage (mild fibrosis) in male albino mice and annotate its phytochemical constituents as well. The extract displayed substantial antioxidant activities in vitro and high content of flavonoids and other phenolic compounds. Oral administration of TFAE (especially high dose) significantly suppressed (but with different degrees) the incidence and severity of CCl4 liver toxicity by activating the hepatic antioxidant defense mechanisms, modulating hepatic functions, and decreasing the production of lipid peroxidation, pro-inflammatory mediators, and pro-fibrotic proteins expression including COL1A1, Fn, and TGF-ß1. These activities might be attributed to the presence of 58 secondary metabolites (identified by LC-MS), mainly phenolic acids, flavonoids and diterpenoids that were able, according to molecular docking, to bind to the inhibitor's binding site of three protein targets involved in liver inflammation and fibrosis. These results showcase the antioxidant and anti-inflammatory properties of Thyme (Thymus fontanesii), illustrate the protective and beneficial effects of the plant against CCl4-induced hepatic toxicity in mice, and support its consumption, traditional uses and promotes its valorization as nutraceutical product.

Investigation on medicinal plants' therapeutic potential has gained substantial importance in the discovery of novel effective and safe therapeutic agents. The present study is aimed at investigating the hepatoprotective potential of Seriphidium kurramense methanolic extract (SKM) against carbon tetrachloride- (CCl4-) induced hepatotoxicity in rats. S. kurramense is one of the most imperative plants for its various pharmacological activities. Therefore, this study was aimed at evaluating the hepatoprotective potential against CCl4-induced liver toxicity. The serum samples were analyzed for alanine aminotransferase (ALT) and aspartate aminotransferase (AST) together with the oxidative stress mediator levels as nitric oxide (NO), malondialdehyde (MDA), glutathione (GSH), reduced glutathione (GSH), and superoxide dismutase (SOD) as well as peroxidation and H2O2 activity. CCl4 administration resulted in an elevated free radical generation, altered liver marker (AST and ALT) enzymes, reduced antioxidant enzyme, and increased DNA damage. Methanolic extract of S. kurramense decreased CCl4-induced hepatotoxicity by increasing the antioxidant status and reducing H2O2 and nitrate content generation as well as reducing DNA damage. Additionally, SKM reversed the morphological alterations induced by CCl4 in the SKM-treated groups. These results demonstrated that SKM displayed hepatoprotective activity against CCl4-induced hepatic damage in experimental rats.
