Abstract
Liver fibrosis is a reversible damage-repair response, the pathological features of which mainly include damage to hepatocytes, sinusoid capillarization, hepatic stellate cells activation, excessive accumulation of extracellular matrix and inflammatory response. Although some treatments (including drugs and stem cell therapy) for these pathological features have been shown to be effective, more clinical trials are needed to confirm their effectiveness. In recent years, nanomaterials-based therapies have emerged as an innovative and promising alternative to traditional drugs, being explored for the treatment of liver fibrosis diseases. Natural nanomaterials (including extracellular vesicles) and synthetic nanomaterials (including inorganic nanomaterials and organic nanomaterials) are developed to facilitate drug targeting delivery and combination therapy. In this review, the pathological features of liver fibrosis and the current anti-fibrosis drugs in clinical trials are briefly introduced, followed by a detailed introduction of the therapeutic nanoagents for the precise delivery of anti-fibrosis drugs. Finally, the future development trend in this field is discussed.

Abstract
Progressive hepatic damage and fibrosis are major features of chronic liver diseases of different etiology, yet the underlying molecular mechanisms remain to be fully defined. N-RAS, a member of the RAS family of small guanine nucleotide-binding proteins also encompassing the highly homologous H-RAS and K-RAS isoforms, was previously reported to modulate cell death and renal fibrosis; however, its role in liver damage and fibrogenesis remains unknown. Here, we approached this question by using N-RAS deficient (N-RAS-/-) mice and two experimental models of liver injury and fibrosis, namely carbon tetrachloride (CCl4) intoxication and bile duct ligation (BDL). In wild-type (N-RAS+/+) mice both hepatotoxic procedures augmented N-RAS expression in the liver. Compared to N-RAS+/+ counterparts, N-RAS-/- mice subjected to either CCl4 or BDL showed exacerbated liver injury and fibrosis, which was associated with enhanced hepatic stellate cell (HSC) activation and leukocyte infiltration in the damaged liver. At the molecular level, after CCl4 or BDL, N-RAS-/- livers exhibited augmented expression of necroptotic death markers along with JNK1/2 hyperactivation. In line with this, N-RAS ablation in a human hepatocytic cell line resulted in enhanced activation of JNK and necroptosis mediators in response to cell death stimuli. Of note, loss of hepatic N-RAS expression was characteristic of chronic liver disease patients with fibrosis. Collectively, our study unveils a novel role for N-RAS as a negative controller of the progression of liver injury and fibrogenesis, by critically downregulating signaling pathways leading to hepatocyte necroptosis. Furthermore, it suggests that N-RAS may be of potential clinical value as prognostic biomarker of progressive fibrotic liver damage, or as a novel therapeutic target for the treatment of chronic liver disease.

Abstract
The platelet‑derived growth factor (PDFG) signaling pathway exerts persistent activation in response to a variety of stimuli and facilitates the progression of hepatic fibrosis. Since this pathway modulates a broad spectrum of cellular processes, including cell growth, differentiation, inflammation and carcinogenesis, it has emerged as a therapeutic target for hepatic fibrosis and liver‑associated disorders. The present review exhibits the current knowledge of the role of the PDGF signaling pathway and its pathological profiles in hepatic fibrosis, and assesses the potential of inhibitors which have been investigated in the experimental hepatic fibrosis model, in addition to the clinical challenges associated with these inhibitors.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the most common liver disease in the western world with prevalence of 20–33%. NAFLD comprises a pathological spectrum. Nonalcoholic fatty liver (NAFL) is at one end and consists of simple hepatic steatosis. On the contrary, nonalcoholic steatohepatitis (NASH) consists of steatosis, inflammation, and ballooning degeneration and can progress to cirrhosis. Despite the rising incidence, definitive treatment for NAFLD, specifically NASH, has not yet been established. Lifestyle modification with dietary changes combined with regular aerobic exercise, along with multidisciplinary approach including cognitive behavior therapy, has been shown to be an effective therapeutic option, even without a significant weight loss. Pioglitazone and vitamin E have shown to be most effective in NASH patients. Surgery and weight loss medication are effective means of weight loss but can potentially worsen NASH related fibrosis. Other agents such as n-3 polyunsaturated fatty acids, probiotics, and pentoxifylline along with herbal agent such as milk thistle as well as daily intake of coffee have shown potential benefits, but further well organized studies are definitely warranted. This review focuses on the available evidence on pharmaceutical and nonpharmaceutical therapy in the treatment and the prevention of NAFLD, primarily NASH.

Abstract
Platelet derived growth factor (PDGF) signaling plays an important role in activated hepatic stellate cells and portal fibroblast proliferation, chemotaxis, migration and cell survival. PDGF receptors and ligands are upregulated in experimental liver fibrotic models as well as in human liver fibrotic diseases. Blocking of PDGF signaling ameliorates experimental liver fibrogenesis. The plurality of molecular and cellular activities of PDGF and its involvement in initiation, progression and resolution of hepatic fibrogenesis offers an infinite number of therapeutic possibilities. These include the application of therapeutic antibodies (e.g. AbyD3263, MOR8457) which specifically sequester individual PDGF isoforms or the inhibition of PDGF isoforms by synthetic aptamers. In particular, the isolation of innovative slow off-rate modified aptamers (e.g., SOMAmer SL1 and SL5) that carry functional groups absent in natural nucleic acids by the Systematic Evolution of Ligands by EXponential (SELEX) enrichment technique offers the possibility to design high affinity aptamers that target PDGF isoforms for clinical purposes. Dominant-negative soluble PDGF receptors are also effective in attenuation of hepatic stellate cell proliferation and hepatic fibrogenesis. Moreover, some multikinase inhibitors targeting PDGF signaling have been intensively tested during the last decade and are on the way into advanced preclinical studies and clinical trials. This narrative review aims to gauge the recent progression of research into PDGF systems and liver fibrosis.

Abstract
BACKGROUND Although fascioliasis has been relatively well studied, little is known about the molecular basis of this disease. This is particularly relevant, considering the very different response that sheep have to Fasciola hepatica relative to cattle. The acute phase of this disease is severe in sheep, whereas chronic fascioliasis is more common in cattle. METHODS To begin to explore the host-response to Fasciola in sheep and improve the understanding of the host-pathogen interactions during the parasite's migration through liver parenchyma to the bile duct, we used RNA sequencing (RNA-seq) to investigate livers from sheep infected for eight weeks compared with those from uninfected controls. RESULTS This study identified 572 and 42 genes that were up- and down-regulated, respectively, in infected livers relative to uninfected controls. Our molecular findings provide significant new insights into the mechanisms linked to metabolism, fibrosis and tissue-repair in sheep, and highlight the relative importance of specific components of immune response pathways, which appear to be driven toward a suppression of inflammation. CONCLUSIONS This study is, to our knowledge, the first detailed investigation of the transcriptomic responses in the liver tissue of any host to F. hepatica infection. It defines the involvement of specific genes associated with the host's metabolism, immune response and tissue repair/regeneration, and highlights an apparent overlapping function of many genes involved in these processes.

Abstract
BACKGROUND Hepatic stellate cells (HSCs) have a key role in the formation of hepatic fibrosis. The active form of vitamin D, 1,25(OH)2D3, has been found to have antiproliferative and antifibrotic effects in various tissues including liver. Farnesylthiosalicylic acid (FTS), a novel Ras antagonist, was also found to inhibit hepatic fibrosis. AIMS The purpose of this study was to examine the antiproliferative and antifibrotic effects of the combined treatment of 1,25(OH)2D3 and FTS on primary cultured HSCs. METHODS Primary HSCs, isolated from rat's livers, were treated with 1,25(OH)2D3, FTS or a combination of both. Proliferation was assessed by bromodeoxyuridine. Expression of p-ERK, ERK, Ras-GTP, total-Ras, CyclinD1 and fibrotic markers was measured by western blotting analysis and real-time PCR. Cytotoxicity was assessed by lactate dehydrogenase method. RESULTS The combined treatment inhibited HSCs proliferation by threefold. The effect was synergistic and non-cytotoxic. In concordance, the combined treatment suppressed CyclinD1 expression by ~2-fold, whereas 1,25(OH)2D3 or FTS alone showed a significantly lower inhibitory effect. The effect of the combined treatment on CyclinD1 expression was mediated via Ras-GTP and p-ERK signal transduction pathway. The effect on fibrotic markers showed that 1,25(OH)2D3 decreased collagen Iα1 expression by ~40%, FTS by ~50% and the combined treatment by ~60%. 1,25(OH)2D3 inhibited tissue inhibitor of metalloproteinases-1 (TIMP-1) expression by 20%. FTS alone or 1,25(OH)2D3 + FTS inhibited TIMP-1 expression by 60%. FTS inhibited transforming growth factor-β (TGF-β) expression by 25%, while 1,25(OH)2D3 had no effect. CONCLUSION Although the combination of 1,25(OH)2D3 and FTS did not demonstrate an additive antifibrotic effect, it showed a synergistic antiproliferative effect on primary HSCs. Therefore, the combined treatment may have a potential therapeutic value in the initiation of fibrotic process.

Abstract
Hepatic stellate cells (HSCs) are the major producers of collagen in the liver. Their conversion from resting cells to proliferative, contractile, and activated cells is a critical step leading to liver fibrosis that is characterized by the deposition of excessive extracellular matrix. Interleukin-1 (IL-1) may play a role in maintaining HSC in a proliferative state that is responsible for hepatic fibrogenesis. The aim of this study was to study the roles of the IL-1 type I receptor (IL-1R1), c-Jun N-terminal kinase (JNK), and activation protein-1 (AP-1) in IL-1β-mediated proliferation in rat HSCs. We showed that IL-1β can upregulate proliferation in rat HSCs; however, inhibition of the JNK pathway could inhibit HSCs proliferation. Furthermore, IL-1β activated IL-1R1 expression, the JNK signaling pathway, and AP-1 activity in a time-dependent manner in rat HSCs. These data demonstrate that IL-1β could promote the proliferation of rat HSCs and that the IL-1R1, JNK, and AP-1 pathways were involved in this process. In summary, IL-1β-induced proliferation is possibly mediated by the IL-1R1, JNK, and AP-1 pathways in rat HSCs. Therefore, drugs that block these pathways may inhibit the proliferation of HSCs and suppress liver fibrosis.

Abstract
INTRODUCTION The extracellular signal-regulated kinase (ERK) mitogen-activated protein kinase pathway, also known as the MEK/ERK1/2 kinase cascade, has recently been implicated in the regulation of lipid metabolism and fatty liver disease. However, its functional effect on cellular fatty acid composition is unknown. Herein, we examined the effect of a pharmacological inhibitor of MEK, the upstream kinase activator of ERK1/2, on fatty acid composition of hepatocellular carcinoma cell line HepG2. METHODS HepG2 cells cultured in RPMI-1640 were exposed to the commonly used ERK1/2 pathway inhibitor PD98059 and were investigated with respect to fatty acid composition by gas-liquid chromatography. RESULTS Exposure of cells to the ERK1/2 pathway inhibitor induced an increase in monounsaturated fatty acids and the fatty acid desaturation index and a decrease in polyunsaturated fatty acid content. Specifically, we showed a significant increase of oleic acid (18:1n-9; +29%, P=0.003) and arachidonic acid (20:4n-6)/linoleic acid (18:2n-6) ratio (3.5-fold; P<0.001) in HepG2 cells. CONCLUSION Cellular fatty acid composition of HepG2 cells appeared to be differentially regulated by ERK1/2 pathway, thus suggesting related metabolic pathways as potential mediators of the effects of ERK1/2 signaling on hepatic fatty acid composition.

Abstract
BACKGROUND/AIM YiGanKang, a combination of Chinese herbs, has anti-fibrosis effects in chronic liver diseases. The present study tries to demonstrate differential role of YiGanKang Decoction in interleukin-1β (IL-1β) induction of the type I receptor (IL-1RI) and the activator protein 1 (AP-1) in rat hepatic stellate cell (HSC). METHODS Flow cytometry was used to detect the IL-1RI expression. Electrophoretic mobility shift assays was used to detect AP-1 activity. RESULTS IL-1RI expression after IL-1β treatment for 0, 2, 10, 60, and 120 min was 227.08 (13.15), 268.43 (8.93), 442.97 (7.00), 367.66 (14.70), and 261.58 (15.08), respectively. The differences between IL-1RI expression after treatment for 10 and 60 min were significantly higher than the corresponding values in the control (P<0.01, P<0.01, respectively); After pretreatment with YiGanKang Decoction, IL-1RI expression induced by IL-1β was not decrease obviously; IL-1β could activate AP-1 in rat HSCs (P<0.01). Meanwhile YiGanKang Decoction could inhibit activity of AP-1 induced by IL-1β (P<0.01), and the inhibition rate was 42.71%. CONCLUSION YiGanKang Decoction could not decrease IL-1RI expression, but it could inhibit activity of AP-1 in rat HSCs induced by IL-1β.

Abstract
BACKGROUND Ras proteins are crucial for cell differentiation and proliferation. Targeting Ras with farnesylthiosalicylic acid (FTS), a Ras antagonist, has been suggested as a therapeutic strategy in proliferative and inflammatory diseases. AIMS To examine the role of Ras and the therapeutic potential of FTS in experimental colitis. METHODS Colitis was induced in 26 mice by adding 2.5% dextran sodium sulfate to their drinking water for 7 days during which 12 study mice were treated with FTS and 14 control mice were given normal saline. Two additional controls included 10 naïve mice treated with FTS and 7 naïve non-treated mice. The animals were followed clinically and sacrificed after 7 days. Their colons were isolated for histological assessment and for measurement of myeloperoxidase activity (MPO), tumor necrosis factor-α(TNF-α), and interleukin-1β(Il-1β) levels. Ras and activated Ras expression was determined by immunoblotting assays. T cell populations in the colon and spleen were analyzed by flow-cytometry. RESULTS FTS induced a 2.1-fold reduction in activated Ras levels (P < 0.004). FTS-treated mice had lower disease activity scores (3.9 ± 1.7 vs. 7.5 ± 2.3, P < 0.001), and lower levels of MPO activity (1.65 ± 0.6 vs. 2.6 ± 0.8 units/g, P < 0.007), Il-1β (2.4 ± 3.6 vs. 24.3 ± 17.5 pg/mg, P < 0.01) and TNF-α (0.63 ± 0.5 vs. 1.9 ± 1 pg/mg, P < 0.04). FTS increased regulatory T cell population in the spleen (1.9 ± 0.4-fold, P < 0.04), and decreased effector T cell populations in the colon and spleen by 24 ± 3% (P < 0.03) and 27 ± 1% (P < 0.02), respectively. FTS had no remarkable side effects. CONCLUSIONS Ras is involved in the inflammatory processes of induced colitis in mice and its inhibition by FTS ameliorates the severity of the inflammation.

Abstract
Interleukin-1 (IL-1) may play a role in maintaining hepatic stellate cell (HSC) in activated state that is responsible for hepatic fibrogenesis. However, the signal transduction pathway that is stimulated by IL-1 in HSC remains to be fully elucidated. The aims of this study were to investigate the role of c-Jun N-terminal kinase (JNK) and p38/activation protein (AP-1) in IL-1β-mediated type I collagen synthesis in rat HSCs. Here, we show that IL-1β could activate JNK and p38 in a time-dependent manner, and that inhibition of the JNK pathway could increase collagen synthesis; however, inhibition of the p38 pathway could inhibit collagen synthesis. Furthermore, IL-1β activated AP-1 in a time-dependent manner in rat HSCs. These data demonstrate that L-1β could promote the synthesis of type I collagen in rat HSCs, and the JNK and p38/AP-1 pathways were involved in this process. In summary, IL-1β-induced collagen synthesis is possibly mediated by cytoplasmic JNK and p38/AP-1 pathways. Therefore, drugs that block the p38/AP-1 pathway may inhibit liver extracellular matrix synthesis and suppress liver fibrosis.

Abstract
Liver fibrosis is a major cause of morbidity and mortality worldwide due to chronic viral hepatitis and, more recently, from fatty liver disease associated with obesity. Hepatic stellate cell activation represents a critical event in fibrosis because these cells become the primary source of extracellular matrix in liver upon injury. Use of cell-culture and animal models has expanded our understanding of the mechanisms underlying stellate cell activation and has shed new light on genetic regulation, the contribution of immune signaling, and the potential reversibility of the disease. As pathways of fibrogenesis are increasingly clarified, the key challenge will be translating new advances into the development of antifibrotic therapies for patients with chronic liver disease.

N1-acetyl substituted pyrrolidine derivative CIP-A5: a novel compound that could ameliorate liver cirrhosis through modulation of hepatic stellate cell activity. Toxicol In Vitro 2011; 25:897-904.

Abstract
(2S,4R)-methyl 1-acetyl-4-(N-(4-bromophenyl)sulfamoyloxy)pyrrolidine-2-carboxylate (CIP-A5) is the N1-acetyl substituted pyrrolidine derivative which was designed against the structure of matrix metalloproteinase (MMP-2) and MMP-9. CIP-A5 has been considered as a candidate compound for treatment of liver cirrhosis. In this study, we evaluated the efficacy of CIP-A5 on the activity of hepatic stellate cells. CIP-A5 prevented the transforming growth factor β (TGF-β)-induced proliferation of hepatic stellate HSC-T6 cells as estimated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. CIP-A5 stimulated MMPs activity as evidenced by an increase of degradation of succinylated gelatin. Gelatin zymography analysis showed that CIP-A5 stimulated the secretion and activity of MMP-2 and MMP-9 in HSC-T6 cells. This stimulatory effect on MMPs was verified by the observation of increased expression of MMP-2 and MMP-9 as evaluated by Western blot assay. At the same time, a significant decrease of the expression of tissue inhibitors of matrix metalloproteinases-1 (TIMP-1) was observed, suggesting a modulation of the balance of MMPs/TIMPs in hepatic stellate cells. CIP-A5 treatment also resulted in suppression of the profibrogenic cytokines, such as TGF-β, tumor necrosis factor alpha (TNF-α) and connective tissue growth factor (CTGF) in HSC-T6 cells. CIP-A5 did not have cytotoxicity to human normal hepatic cells. These results implied that CIP-A5 could selectively ameliorate the process of liver cirrhosis through modulation of activated hepatic stellate cell activity, which offers hope for prevention and treatment of this devastating end-stage liver disease.
