Exp Cell Res 2021; 407:112828. [PMID: 34508745 DOI: 10.1016/j.yexcr.2021.112828] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Revised: 08/30/2021] [Accepted: 09/06/2021] [Indexed: 12/12/2022]
Abstract
BACKGROUND Particulate matter≤ 2.5 μm (PM2.5) is a type of environmental agent associated with air pollution, which induces hepatic fibrosis. However, the function and mechanism of PM2.5 on hepatic stellate cell (HSC) proliferation and fibrosis remain largely unknown. METHODS Human HSC line (LX-2) and murine HSCs were exposed to various doses of PM2.5. microRNA (miR)-411 expression was detected via quantitative reverse transcription polymerase chain reaction (qRT-PCR). Cell proliferation, fibrosis, mitochondrial dynamics dysfunction and mitophagy were determined via cell counting kit-8 (CCK-8), qRT-PCR, Western blotting and immunofluorescence. RESULTS PM2.5 facilitated HSC proliferation and fibrosis via increasing the levels of ACTA2, Collagen 1, TIMP1 and TGF-β1. PM2.5 reduced miR-411 expression, and contributed to mitochondrial dynamics dysfunction via increasing Drp1 and decreasing OPA1, TOM20 and PGC-1α levels. PM2.5 promoted mitophagy by upregulating the levels of Beclin-1, LC3II/I, PINK1 and Parkin. miR-411 overexpression or autophagy blockage using 3-methyladenine (3-MA) relieved PM2.5-mediated cell proliferation and fibrosis-associated factor expression in HSCs. Drp1 was targeted by miR-411. miR-411 mitigated PM2.5-induced mitophagy via targeting Drp1. Drp1 overexpression abolished the inhibitory role of miR-411 in cell proliferation and fibrosis-associated factor levels in HSCs. CONCLUSION PM2.5 induced HSC activation and fibrosis via promoting Drp1-mediated mitophagy by decreasing miR-411, thereby causing liver fibrosis.

Abstract
Alcoholic liver disease greatly affects human health. Previous studies have identified that microRNAs (miRNAs) are associated with the pathogenesis of alcoholic liver fibrosis (ALF). Therefore, the present study explored the regulatory mechanism of miR-148a-3p in ALF. An ALF model was established in rats by alcohol gavage, followed by treatment with miR-148a-3p. Reverse transcription-quantitative (RT-q) PCR was performed to detect miR-148a-3p expression in the rat liver tissues. The levels of lactate dehydrogenase (LDH), aspartate aminotransferase (AST), alanine transaminase (ALT) and alkaline phosphatase (ALP) were determined by enzyme-labeled colorimetry. Liver damage was evaluated by liver indices and histology. The direct target gene of miR-148a-3p was predicted by a dual luciferase reporter assay. The effects of miR-148a-3p and miR-148a-3p in combination with receptor tyrosine-protein kinase erbB-3 (ERBB3) on HSC-T6 cell viability and apoptosis were detected by MTT and flow cytometry assays, respectively. Western blotting and RT-qPCR assays were performed to detect the expression levels of proteins and mRNA associated with fibrosis and apoptosis. The data showed that miR-148a-3p mimics inhibited the expression levels of AST, ALT, ALP, LDH, α-SMA and type I collagen in the model, decreased the liver indices, and improved the liver damage caused by alcohol. ERBB3, which was predicted as the direct target gene of miR-148a-3p, reversed the effects of ERBB3 on promoting cell viability and inhibiting apoptosis. Concomitantly, miR-148a-3p reversed the increased expression of Bcl-2 and inhibited the expression levels of Bax and c-cleaved-3 caused by ERBB3. These data suggested that miR-148a-3p regulated ALF and the viability and apoptosis of hepatic stellate cells through targeting ERBB3.

Abstract
Resistance to therapy is a major obstacle to cancer treatment. It may exist from the beginning, or it may develop during therapy. The review focusses on oncolytic Newcastle disease virus (NDV) as a biological agent with potential to break therapy resistance. This avian virus combines, upon inoculation into non-permissive hosts such as human, 12 described anti-neoplastic effects with 11 described immune stimulatory properties. Fifty years of clinical application of NDV give witness to the high safety profile of this biological agent. In 2015, an important milestone was achieved, namely the successful production of NDV according to Good Manufacturing Practice (GMP). Based on this, IOZK in Cologne, Germany, obtained a GMP certificate for the production of a dendritic cell vaccine loaded with tumor antigens from a lysate of patient-derived tumor cells together with immunological danger signals from NDV for intracutaneous application. This update includes single case reports and retrospective analyses from patients treated at IOZK. The review also presents future perspectives, including the concept of in situ vaccination and the combination of NDV or other oncolytic viruses with checkpoint inhibitors.

Abstract
The standard of care for early hepatobiliary cancers (HBC) includes surgical resection. Liver transplantations or locoregional therapies are beneficial in early hepatocellular carcinoma (HCC) under certain circumstances. Systemic treatments have some benefit in advanced HBC, though long-term prognosis remains poor. We evaluated the role of oncolytic viruses in the treatment of HBCs through a systematic literature review. The recombinant vaccinia virus JX-594 improved median survival in patients with local/metastatic HCC more strongly at high dose than at low dose (14.1 vs 6.7 months; p = 0.08) in a Phase II study. A Phase III study with JX-594 and sorafenib in advanced HCC is ongoing. No survival benefit in HCC was seen with two other recombinant adenoviruses (Ad-TK and DL1520). Several preclinical trials using oncolytic viruses in HBC showed promising results, warranting clinical studies.

Abstract
Activated hepatic stellate cells (HSCs) release pro-inflammatory and pro-fibrogenic factors. CXC chemokine-ligand-1 (CXCL1) is expressed on HSCs. We previously found that the CD147 is overexpressed in activated HSCs. In this study, we showed an important role of CD147 in promoting liver fibrosis by activating HSCs and upregulating expression of chemokines. Specifically, we found that CD147 specific deletion in HSCs mice alleviated CCl4-induced liver fibrosis and inhibited HSCs activation. Overexpression of CD147 upregulated the secretion of CXCL1. Meanwhile, CXCL1 promoted HSCs activation through autocrine. Treating with PI3K/AKT inhibitor could effectively suppress CD147-induced CXCL1 expression. Taken together, these findings suggest that CD147 regulates CXCL1 release in HSCs by PI3K/AKT signaling. Inhibition of CD147 attenuates CCl4-induced liver fibrosis and inflammation. Therefore, administration of targeting CD147 could be a promising therapeutic strategy in liver fibrosis.

Abstract
Newcastle disease (ND) is one of the most important diseases of poultry worldwide. In the last decades, molecular research has gained a lot of new information about its causative agent, newcastledisease virus (NDV). In poultry industry, certain strains of NDV have been used for preventive vaccination for more than 60 years. NDV has also been applied to cancer patients with beneficial effects for about 50 years, but this is less well known. The molecular basis for these differential effects of NDV in birds and man have been elucidated in the last decades and are explained in this review. The anti-neoplastic and immune-stimulatory properties in non-permissive hosts such as mouse and man have to do with the strong type I interferon responses induced in these foreign species. Additionally, NDV has the potential to break various types of tumor resistances and also to affect liver fibrosis. A main section is devoted to the benefits of clinical application of NDV and NDV-based vaccines to cancer patients. Reverse genetics technology allowed developing NDV into a vector suitable for gene therapy. Examples will be provided in which genetically engineered NDV is being used successfully as vector against new emerging viruses.

Abstract
In our recent study, we found that the expression levels of total xylose-binding proteins (XBPs) were up-regulated significantly in activated hepatic stellate cells (HSCs); however, the denomination, distribution, and function of the XBPs were uncharted. Herein, 70 XBPs from activated HSCs and 64 XBPs from quiescent HSCs were isolated, identified and annotated. A total of 30 XBPs were up-regulated (all fold change ≥ 1.5, p ≤ 0.05) and 14 XBPs were down-regulated (all fold change ≤ 0.67, p ≤ 0.05) in the activated HSCs. The XBPs were localized at the cytoplasm and cytoplasmic membrane in HSCs and cirrhotic liver tissues by cy/histochemistry. The XBPs (i.e. PDIA6 and CFL2) responsible for the regulation of protein binding were up-regulated and those responsible for the regulation of catalytic activity (i.e. TUBB and MX1) were up-regulated in the activated HSCs. 2 candidates (i.e. PDIA6 and APOA1) were then selected for further verification in the sera of patients with HBV-induced chronic hepatitis/cirrhosis using western blotting and serum microarrays. PDIA6 showed a higher discrimination (Area Under Curves, AUCs = 0.8985, p < 0.0001) relative to APOA1 (AUCs = 0.8738, p < 0.0001) in the sera of patients as biomarker candidate. In conclusion, the precision alteration of the XBPs associated with pathological changes in HSCs during liver fibrosis/cirrhosis may provide pivotal information needed to discover potential glycan-binding protein-related biomarkers for diagnosis of liver fibrosis/cirrhosis and for development of new anti-fibrotic strategies.

Abstract
This review provides an overview of 50 years of basic and clinical research on an oncolytic avian virus, Newcastle Disease Virus (NDV), which has particular anti-neoplastic and immune stimulatory properties. Of special interest is the fact that this biological agent induces immunogenic cell death and systemic anti-tumor immunity. Furthermore, localized oncolytic virotherapy with NDV was shown to overcome systemic tumor resistance to immune checkpoint blockade immunotherapy. Clinical experience attests to low side effects and a high safety profile. This is due among others to the strong virus-induced type I interferon response. Other viral characteristics are lack of interaction with host cell DNA, lack of genetic recombination and independence of virus replication from cell proliferation. In this millennium, new recombinant strains of viruses are being produced with improved therapeutic properties. Clinical applications include single case observations, case series studies and Phase I to III studies.

Abstract
Although the expression levels of total GalNAc-binding proteins (GNBPs) were up-regulated significantly in human hepatic stellate cells (HSCs) activated with transforming growth factor-β1(TGF-β1), yet little is known about the precise types, distribution and sub-cellular localization of the GNBPs in HSCs. Here, 264 GNBPs from the activated HSCs and 257 GNBPs from the quiescent HSCs were identified and annotated. A total of 46 GNBPs were estimated to be significantly up-regulated and 40 GNBPs were estimated to be significantly down-regulated in the activated HSCs. For example, the GNBPs (i.e. BTF3, COX17, and ATP5A1) responsible for the regulation of protein binding were up-regulated, and those (i.e. FAM114A1, ENO3, and TKT) responsible for the regulation of protein binding were down-regulated in the activated HSCs. The motifs of the isolated GNBPs showed that Proline residue had the maximum preference in consensus sequences. The western blotting showed the expression levels of COX17, and PRMT1 were significantly up-regulated, while, the expression level of CLIC1(B5) was down-regulated in the activated HSCs and liver cirrhosis tissues. Moreover, the GNBPs were sub-localized in the Golgi apparatus of HSCs. In conclusion, the precision alteration of the GNBPs referred to pathological changes in liver fibrosis/cirrhosis may provide useful information to find new molecular mechanism of HSC activation and discover the biomarkers for diagnosis of liver fibrosis/cirrhosis as well as development of new anti-fibrotic strategies.

Abstract
Activation of hepatic stellate cells (HSCs) by transforming growth factor-β1 (TGF-β1) initiates HBV-associated fibrogenesis. The mechanism of TGF-β1 modulating HSC activation is not fully uncovered. We hypothesized a positive feedback signaling loop of TGF-β1-CD147 promoting liver fibrogenesis by activation of HSCs. Human HSC cell line LX-2 and spontaneous liver fibrosis model derived from HBV transgenic mice were used to evaluate the activation of molecules in the signaling loop. Wound healing and cell contraction assay were performed to detect the CD147-overexpressed HSC migration and contraction. The transcriptional regulation of CD147 by TGF-β1/Smad4 was determined using dual-luciferase reporter assay and chromatin immunoprecipitation. We found that a positive reciprocal regulation between TGF-β1 and CD147 mediated HSC activation. CD147 over-expression promoted HSC migration and accelerated TGF-β1-induced cell contraction. Phosphorylation of Smad2 and Smad3 in cooperation with Smad4 mediated the TGF-β1-regulated CD147 expression. Smad4 activated the transcription by direct interaction with CD147 promoter. Meanwhile, CD147 modulated the activated phenotype of HSCs through the ERK1/2 and Sp1 which up-regulated α-SMA, collagen I, and TGF-β1 synthesis. These findings indicate that TGF-β1-CD147 loop plays a key role in regulating the HSC activation and combination of TGF-β receptor inhibitor and anti-CD147 antibody might be promised to reverse fibrogenesis.

Abstract
Glycan-binding proteins (GBPs) play an important role in cell adhesion, bacterial/viral infection, and cellular signaling pathways. However, little is known about the precision alteration of GBPs referred to pathological changes in hepatic stellate cells (HSCs) during liver fibrosis. Here, the carbohydrate microarrays were used to probe the alteration of GBPs in the activated HSCs and quiescent HSCs. As a result, 12 carbohydrates (e.g. Gal, GalNAc, and Man-9Glycan) showed increased signal, while seven carbohydrates (e.g. NeuAc, Lac, and GlcNAc-O-Ser) showed decreased signal in activated HSCs. Three carbohydrates (Gal, GalNAc, and NeuAc) were selected and subsequently used to validate the results of the carbohydrate microarrays as well as assess the distribution and localization of their binding proteins in HSCs and liver tissues by cy/histochemistry; the results showed that GBPs mainly distributed in the cytoplasma membrane and perinuclear region of cytoplasm. The immunocytochemistry was further used to verify some GBPs really exist in Golgi apparatus of the cells. The precision alteration and localization of GBPs referred to pathological changes in HSCs may provide pivotal information to help understand the biological functions of glycans how to exert through their recognition by a wide variety of GBPs. This study could lead to the development of new anti-fibrotic strategies.

Abstract
Glycoproteins play important roles in maintaining normal cell functions depending on their glycosylations. Our previous study indicated that the abundance of glycoproteins recognized by concanavalin A (ConA) was increased in human hepatic stellate cells (HSCs) following activation by transforming growth factor-β1 (TGF-β1); however, little is known about the ConA-binding glycoproteins (CBGs) of HSCs. In this study, we employed a targeted glycoproteomics approach using lectin-magnetic particle conjugate-based liquid chromatography-tandem mass spectrometry to compare CBG profiles between LX-2 HSCs with and without activation by TGF-β1, with the aim of discovering novel CBGs and determining their possible roles in activated HSCs. A total of 54 and 77 proteins were identified in the quiescent and activated LX-2 cells, respectively. Of the proteins identified, 14.3% were glycoproteins and 73.3% were novel potential glycoproteins. Molecules involved in protein processing in the endoplasmic reticulum (e.g., calreticulin) and calcium signaling (e.g., 1-phosphatidylinositol-4,5-bisphosphate phosphodiesterase β-2 [PLCB2]) were specifically identified in activated LX-2 cells. Additionally, PLCB2 expression was upregulated in the cytoplasm of the activated LX-2 cells, as well as in the hepatocytes and sinusoidal cells of liver cirrhosis tissues. In conclusion, the results of this study may aid future investigations to find new molecular mechanisms involved in HSC activation and antifibrotic therapeutic targets.

Abstract
Oncolytic viral therapies have recently found their way into clinical application for hepatocellular carcinoma (HCC), a disease with limited treatment options and poor prognosis. Adding to the many intrinsic challenges of in vivo oncolytic viral therapy, is the complex microenvironment of the liver, which imposes unique limitations to the successful delivery and propagation of the virus. The normal liver milieu is characterized by an intricate network of hepatocytes and non-parenchymal cells including Kupffer cells, stellate cells, and sinusoidal endothelial cells, which can secrete anti-viral cytokines, provide a platform for non-specific uptake, and form a barrier to efficient viral spread. In addition, natural killer cells are greatly enriched in the liver, contributing to the innate defense against viruses. The situation is further complicated when HCC arises in the setting of underlying hepatitis virus infection and/or hepatic cirrhosis, which occurs in more than 90% of clinical cases. These conditions pose further inhibitory effects on oncolytic virus (OV) therapy due to the presence of chronic inflammation, constitutive cytokine expression, altered hepatic blood flow, and extracellular matrix deposition. In addition, OVs can modulate the hepatic microenvironment, resulting in a complex interplay between virus and host. The immune system undoubtedly plays a substantial role in the outcome of OV therapy, both as an inhibitor of viral replication, and as a potent mechanism of virus-mediated tumor cell killing. This review will discuss the particular challenges of oncolytic viral therapy for HCC, as well as some potential strategies for modulating the immune system and synergizing with the hepatic microenvironment to improve therapeutic outcome.

Genetically engineered Newcastle disease virus expressing interleukin 2 is a potential drug candidate for cancer immunotherapy. Immunol Lett 2014; 159:36-46.

Abstract
Newcastle disease virus (NDV) is an intrinsically tumor-specific virus, several clinical trials have reported that mesogenic NDV is a safe and effective agent for human cancer therapy. Interleukin 2 (IL2) is a cytokine that stimulates T cell propagation to trigger innate and adaptive immunity. IL2 has been used for cancer therapy and has achieved curative effects. In this study, a recombinant NDV LaSota strain expressing human interleukin 2 (rLaSota/IL2) was generated. The ability of rLaSota/IL2 to express human IL2 was detected in the infected tumor cells. In addition, the activity of IL2 was analyzed. The antitumor potential of rLaSota/IL2 was studied by xenograph mice carrying H22 and B16-F10 cells. Tumor-specific CD4(+) and CD8(+) T cells and MHC II were also analyzed in the two tumor-bearing models. Our study showed that rLaSota/IL2 significantly stimulated tumor-specific cytotoxic T-lymphocyte (CTL) responses and increased regulatory CD4(+) and cytotoxic CD8(+) T cells proliferation. The treatment with rLaSota/IL2 led to tumor regression in tumor-bearing mice and prolonged the survival of tumor-bearing mice. Furthermore, tumor challenging experiments demonstrated that rLaSota/IL2 invoked mice a unique capacity to remember a pathogen through the generation of memory T cells, which protect the host in the event of reinfection and form adaptive immune system. The result indicates that tumor-infiltrating CD4(+) T regulatory cells may denote the effective regression of tumors. Taken together, rLaSota/IL2 has potential for immunotherapy and oncolytic therapy of cancers and may be an ideal candidate for clinical application in future cancer therapy.

Antifibrotic properties of transarterial oncolytic VSV therapy for hepatocellular carcinoma in rats with thioacetamide-induced liver fibrosis. Mol Ther 2013; 21:2032-42.

Abstract
Recombinant vesicular stomatitis virus (VSV) shows promise for the treatment of hepatocellular carcinoma (HCC), but its safety and efficacy when administered in a setting of hepatic fibrosis, which occurs in the majority of clinical cases, is unknown. We hypothesized that VSV could provide a novel benefit to the underlying fibrosis, due to its ability to replicate and cause cell death specifically in activated hepatic stellate cells. In addition to the ability of VSV to produce a significant oncolytic response in HCC-bearing rats in the background of thioacetamide-induced hepatic fibrosis without signs of hepatotoxicity, we observed a significant downgrading of fibrosis stage, a decrease in collagen content in the liver, and modulation of gene expression in favor of fibrotic regression. Together, this work suggests that VSV is not only safe and effective for the treatment of HCC with underlying fibrosis, but it could potentially be developed for clinical application as a novel antifibrotic agent.

HAb18G/CD147 promotes activation of hepatic stellate cells and is a target for antibody therapy of liver fibrosis. J Hepatol 2012; 57:1283-91. [PMID: 22878468 DOI: 10.1016/j.jhep.2012.07.042] [Citation(s) in RCA: 40] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/02/2012] [Revised: 07/23/2012] [Accepted: 07/27/2012] [Indexed: 12/17/2022]
Abstract
BACKGROUND & AIMS Activated hepatic stellate cells (HSCs) located in the Disse's space play a crucial role in liver fibrosis. HAb18G/CD147, a tumor-related glycoprotein, is highly expressed in hepatocellular carcinoma cells and fibroblasts. Whether HAb18G/CD147 plays an important role in the hepatic fibrogenesis is unknown. METHODS Immunohistochemistry for HAb18G/CD147 and α-smooth muscle actin expression in diseased liver tissues was used for correlation analysis. The function of HAb18G/CD147 in fibrogenesis was evaluated with the human HSCs LX-2 cell line and carbon tetrachloride-induced mouse liver fibrosis model. The specific antibody HAb18 targeting HAb18G/CD147 was injected intravenously into the mouse to investigate whether HAb18G/CD147 could be a potential target for liver fibrosis treatment. RESULTS HAb18G/CD147 is highly expressed on activated HSCs in the sinusoid. The positive rates of HAb18G/CD147 expression in human HBV-related liver cirrhosis, liver biopsy with HBV and liver adjacent to hemangioma were 95.6% (65/68), 14.8% (8/54) and 6.4% (8/125), respectively. HAb18G/CD147 expression was significantly correlated with the Child-Pugh grade (r=0.2848, p=0.0186) and with the expression of α-smooth muscle actin in HSCs (r=0.4434, p=0.0002) in liver cirrhosis. Transforming growth factor-β1 upregulated HAb18G/CD147 expression in LX-2 cells. Transfection of HAb18G/CD147 promoted the profibrogenic genes expression. In mouse liver fibrosis model, HAb18G/CD147 expression increased with the development of fibrogenesis and decreased during the liver fibrosis spontaneous recovery. The HAb18 targeting HAb18G/CD147 could attenuate liver fibrosis. CONCLUSIONS These data suggest that HAb18G/CD147 plays a role in HSC activation and is a potential therapeutic target in fibrosis/cirrhosis.

Osteopontin contributes to TGF-β1 mediated hepatic stellate cell activation. Dig Dis Sci 2012; 57:2883-91.

Abstract
BACKGROUND AND PURPOSE Liver fibrosis is characterized by accumulation of extracellular matrix. Our previous study found that osteopontin (OPN) increased in plasma of cirrhotic patients and indicative of cirrhosis staging. The present study was designed to investigate the expression of OPN in liver tissues and plasma of cirrhotic patients and further explore the role of OPN in human hepatic stellate cell (HSC) activation. METHODS We used immunohistochemical staining and enzyme-linked immunosorbent assay to evaluate the expression level of OPN in liver tissues and plasma from cirrhotic patients, respectively. We produced lentivirus particles and infected target cell to manipulate OPN expression. Infection efficiency was determined by real-time RT-PCR and western blot. Cell proliferation was determined using CCK8 assay, and phenotypes of HSC activation were determined by real-time RT-PCR. OPN promoter activity was determined by dual luciferase reporter assay. RESULTS We found that OPN expression in human cirrhotic liver tissues was upregulated compared to normal controls. In addition, its expression correlated with Child-Pugh classification, MELD score and the occurrence of complications. We further explored OPN level in patients' plasma and showed that its level correlated with transforming growth factor-β1 (TGF-β1). In human HSC cell line LX-2, we found that change of OPN expression level could not only affect the proliferation of cells but also the TGF-β1 mediated HSC activation. Moreover, OPN was increased by TGF-β1 stimulation and regulated by TGF-β1 at transcription level. CONCLUSIONS OPN is upregulated in liver tissues and plasma of cirrhotic patients and promotes TGF-β1 mediated HSC activation.

Abstract
Although aberrant glycosylation of human glycoproteins is related to liver fibrosis that results from chronic damage to the liver in conjunction with the activation of hepatic stellate cells (HSCs), little is known about the precision alteration of protein glycosylation referred to the activation of HSCs by transforming growth factor-β1 (TGF-β1). The human HSCs, LX-2 were activated by TGF-β1. The lectin microarrays were used to probe the alteration of protein glycosylation in the activated HSCs compared with the quiescent HSCs. Lectin histochemistry was used to further validate the lectin binding profiles and assess the distribution of glycosidic residues in cells. As a result, 14 lectins (e. g. AAL, PHA-E, ECA and ConA) showed increased signal while 7 lectins (e. g. UEA-I and GNA) showed decreased signal in the activated LX-2 compared with the quiescent LX-2. Meanwhile, AAL, PHA-E and ECA staining showed moderate binding to the cytoplasma membrane in the quiescent LX-2, and the binding intensified in the same regions of the activated LX-2. In conclusion, the precision alteration of protein glycosylation related to the activation of the HSCs may provide useful information to find new molecular mechanism of HSC activation and antifibrotic therapeutic strategies.

Abstract
Newcastle disease virus (NDV), a bird paramyxovirus, is an antitumor agent which has shown benefits to cancer patients. Its antineoplastic efficacy appears to be associated with three properties of the virus: 1. Selective replication in tumor cells. This feature can be studied at the RNA level, for example by RT-PCR, and at the protein level by immunochemistry. 2. Oncolytic properties (of some strains). The use of cultures of tumor cell lines represents a selective model to study direct viral oncolysis at the cellular level. The capacity of NDV to lyse tumor cells can be analyzed in vitro using cytotoxic assays based on the WST1 chemical reagent. The endoplasmic reticulum stress, which is induced by infection with the oncolytic NDV strain MTH-68/H and which plays an important role in the viral oncolytic effects, can be analyzed by Western blotting using specific monoclonal antibodies. Such stress appears as a key component of NDV cytotoxicity. 3. Immunostimulatory capacity. We describe an in vitro test called "Tumor Neutralisation Assay" which allows the analysis of bystander antitumor immune effects induced in human peripheral blood mononuclear cells by NDV. There are two variants, one for oncolytic NDV strains and the other one for nonlytic NDV strains. NDV may use several mechanisms to exert its tumor-killing action: direct cytotoxicity against cancer cells but also nonspecific as well as active-specific antitumor immune responses from the host organism. All the methods described here allow to evaluate the different oncolytic and immunostimulatory capacities of various strains of NDV. They are crucial to harness optimal antitumor activity by appropriate combinations of virus strains and application regimens.

Abstract
Almost 80% of hepatocellular carcinoma (HCC) cases are associated with chronic hepatitis and cirrhosis resulting from inflammation and fibrosis. A three-step process of "inflammation-fibrosis-carcinoma" is believed to be involved in hepatocarcinogenesis. The activation of hepatic stellate cells (HSCs) may serve as an important mediator in the process of inflammation-fibrosis-carcinoma axis, even in tumor metastasis. A remarkable knowledge of activated HSCs in the pathology of HCC development is mostly focused on the liver fibrosis. The molecular links that connects inflammation and cancer in the activation of HSC are not completely known. This highlights urgent need to increase our understanding of the cellular and molecular mechanisms, by which activation of HSCs is involved in the hepatic inflammation, carcinogenesis, and metastasis.
