BACKGROUND AND AIM: Liver cirrhosis (LC) and hepatocellular carcinoma (HCC) are associated with viral hepatitis, especially hepatitis B virus (HBV) and hepatitis C virus (HCV). Whether differences exist in postoperative de novo carcinogenesis from established cirrhosis according to viral etiology remains unclear. METHODS: Data from 313 LC patients with viral hepatitis (HBV-LC, n = 108 and HCV-LC, n = 205) who underwent curative-intent hepatectomy for HCC were retrospectively collected...

Accumulating evidence has indicated that oxidative stress (OS) is associated with the development of hepatocellular carcinoma (HCC). However, the mechanisms remain largely unknown. Normally, OS occurs when the body receives any danger signal-from either an internal or external source-and further induces DNA oxidative damage and abnormal protein expression, placing the body into a state of vulnerability to the development of various diseases such as cancer. There are many factors involved in liver carcinogenesis, including hepatitis B virus (HBV) and hepatitis C virus (HCV) infection, alcohol abuse, and nonalcoholic fatty liver disease (NAFLD)...

Persistent hepatitis C virus (HCV) infection is associated with high incidence of hepatocellular carcinoma (HCC), the most common primary malignancy of the liver with over half a million new cases diagnosed annually worldwide. The aryl hydrocarbon receptor (AhR) is a ubiquitously expressed transcription factor and its activation by environmental chemicals and by its endogenous ligand kynurenine (Kyn) has been implicated in a variety of tumour-promoting processes such as transformation, tumorigenesis and in immunosuppression that enables tumour survival and growth...

The current review explores the role of emerging molecular contributing factors in liver carcinogenesis on top of hepatitis C virus (HCV). Here we will try to discuss the role genetic and epigenetic factors in pathogenesis of hepatocellular carcinoma. Understanding the role of these factors will help in discovering the mystery of liver carcinogenesis on top of chronic HCV infection. Moreover, use of the studied molecular factors will provide the hepatologists with tailored diagnostic promising biomarkers and flatten the way for establishment of emerging molecular treatment based on exploring the molecular subscription of this aggressive liver cancer...

OBJECTIVE: We have reported about real-time tissue elastography (RTE), which displays relative strain by measuring the relative distortion of the tissue, and found this information to be useful for diagnosing liver fibrosis. However, its use in predicting hepatocellular carcinoma has not been reported as yet. Here, we investigated RTE to predict liver carcinogenesis in patients with chronic hepatitis C virus (HCV) infection. METHODS: We enrolled 160 patients with chronic HCV, who were followed up for 39...

Chronic infection by hepatitis C virus (HCV) is a major risk factor for the development of hepatocellular carcinoma (HCC). Despite the clear clinical importance of virus-associated HCC, the underlying molecular mechanisms remain largely unclarified. Oxidative stress, in particular, DNA lesions associated with oxidative damage, plays a major role in carcinogenesis, and is strongly linked to the development of many cancers, including HCC. However, in identifying hepatocytes with HCV viral RNA, estimates of the median proportion of HCV-infected hepatocytes have been found as high as 40% in patients with chronic HCV infection...

Gastrointestinal (GI) cancers are the leading cause of mortality worldwide. These cancers are the end result of a complex interplay between gene and environment. Bacteria, parasites, and viruses have been implicated in some cancers. Recent data have put at focus the gut microbiome as the key player firing tumorigenesis. Experimental and human studies have provided evidence on the role of microbiota in cancer development. Although subject to changes in different settings such as antibiotic treatment, diet or lifestyle, our microbiome is quite stable and is capable of increasing susceptibility to cancer or decrease and halt its progression...

We conducted a survey on the recognition of infection, status of outpatient treatment, and treatment history in hepatitis virus-associated hepatocellular carcinoma patients admitted to our department between 2005 and 2014. We compared these parameters in 75 patients with primary hepatitis B virus-associated hepatocellular carcinoma (HBV-HCC) and 307 patients with hepatitis C virus-associated hepatocellular carcinoma (HCV-HCC). Based on the presence or absence of outpatient treatment in medical institutions at the time of HCC diagnosis, the patients were divided into an outpatient treatment-free group or an outpatient treated group...

Hepatitis virus infection is a leading cause of chronic liver disease, including cirrhosis and hepatocellular carcinoma (HCC). Although anti-viral therapies against hepatitis B virus (HBV) and hepatitis C virus (HCV) have dramatically progressed during the past decade, the estimated number of people chronically infected with HBV and/or HCV is ~370 million, and hepatitis virus-associated hepatocarcinogenesis is a serious health concern worldwide. Understanding the mechanism of virus-associated carcinogenesis is crucial toward both treatment and prevention, and the recently developed whole genome/exome sequencing analysis using next-generation sequencing technologies has contributed to unveiling the landscape of genetic and epigenetic aberrations in not only tumor tissues but also the background liver tissues underlying chronic liver damage caused by hepatitis virus infection...

Infection of hepatitis C virus (HCV) is associated with primary hepatocellular carcinoma (HCC). However, its underlying molecular mechanisms remain enigmatic. Tumor necrosis factor-α-induced protein 8-like 2 (TIPE2), a new negative regulator of immunity, plays significant roles in modulating inflammation and tumorigenesis. We hypothesized that TIPE2 might be involved in the development of HCV-induced HCC. To test this hypothesis, the expression of TIPE2 was determined by Western blot in the tumor and pericarcinomatous tissues collected from ten HCV-positive HCC patients; the interaction between TIPE2 and HCV-encoded non-structural proteins was analyzed by immunoprecipitation and immunofluorescence assays, and tumorigenesis and its mechanisms were studied in cell models and nude mice...

BACKGROUND/AIM: It has been reported that type 2 helper T-cell (Th2) cytokines down-regulate antitumor immunity, while Th1 cytokines up-regulate it. We previously reported that hepatocarcinogenesis was associated with Th2 dominance in patients with hepatitis C virus (HCV)-related liver cirrhosis (LC), but we did not determine whether Th2 dominance induced carcinogenesis or carcinogenesis led to Th2 dominance. The aim of the study was to clarify whether Th2 dominance induces carcinogenesis or vice versa in patients with HCV-related liver diseases...

BACKGROUND: Hepatocellular carcinoma (HCC) is associated with inflammation, and roughly 30 % of the global population shows serological evidence of current or past infection with hepatitis B or hepatitis C virus. Resident hepatic macrophages, known as Kupffer cells (KCs), are considered as the specific tumor-associated macrophages (TAMs) of HCC, and can produce various cytokines-most importantly interleukin (IL)-6-to promote tumorigenesis of HCC. However, the roles of KCs and IL-6 in carcinogenesis in the liver are still unclear...

The molecular mechanisms of hepatocellular carcinoma (HCC) carcinogenesis are still not fully understood. DNA repair defects may influence HCC risk. The aim of the study was to look for potential genetic variants of DNA repair genes associated with HCC risk among patients with alcohol- or viral-induced liver disease. We performed four case-control studies on 2,006 European- (Derivation#1 and #2 studies) and African-ancestry (Validation#1 and #2 studies) patients originating from several cohorts in order to assess the association between genetic variants on DNA repair genes and HCC risk using a custom array encompassing 94 genes...

Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide with high prevalence and lethality. Hepatitis B virus (HBV) and Hepatitis C virus (HCV) infection are the major risk factors for HCC. Long noncoding RNAs (lncRNAs) are involved in diverse biological processes, and aberrant lncRNA expression is relevant to many human diseases including HCC. Although many researches on HCC have been reported and lncRNAs roles in carcinogenesis have been highlighted recently, reports on roles of lncRNAs in HBV/HCV-induced HCC are limited...

Sulfatides, a type of glycosphingolipid, are associated with carcinogenesis. Peroxisome proliferator-activated receptor α (PPARα) is involved in the regulation of sulfatide metabolism as well as in cancer development. We previously reported that transgenic (Tg) mice expressing hepatitis C virus core protein (HCVcp) exhibited age-dependent PPARα activation and carcinogenesis in liver. However, the metabolism of sulfatides in hepatocellular carcinoma is unknown. To examine the relationship between sulfatide metabolism, carcinogenesis, HCVcp, and PPARα, age-dependent changes of these factors were examined in HCVcpTg, PPARα inhibitor-treated HCVcpTg, and non-Tg mice...

BACKGROUND: It has been reported that liver metastasis rarely occurs in a cirrhotic/hepatitic liver. Thus, coexistence of liver metastasis and hepatocellular carcinoma has been scarcely reported. To the best of our knowledge, there are no cases with hepatocellular carcinoma, which developed during an observational period after hepatectomy for colorectal liver metastasis, in the worldwide English literature. Here we present a case of hepatocellular carcinoma which occurred during a period between the first and second hepatectomy for repeated colorectal liver metastasis...

Chronic Hepatitis C Virus (HCV) infection is a major risk for hepatocellular carcinoma (HCC) development. HCV Core protein has been associated with the modulation of potentially oncogenic cellular processes and E2 protein has been useful in evolutive studies to analyze the diversity of HCV. Thus, the aim of this study was to evaluate HCV compartmentalization in tumoral, non-tumoral liver tissue and serum and to identify viral mutations potentially involved in carcinogenesis. Samples were obtained from four patients with HCC who underwent liver transplantation...

UNLABELLED: Hepatitis C virus (HCV)-induced chronic liver disease is a leading cause of hepatocellular carcinoma (HCC). However, the molecular mechanisms underlying HCC development following chronic HCV infection remain poorly understood. MicroRNAs (miRNAs) play an important role in homeostasis within the liver, and deregulation of miRNAs has been associated with liver disease, including HCC. While host miRNAs are essential for HCV replication, viral infection in turn appears to induce alterations of intrahepatic miRNA networks...

Alcoholic liver disease (ALD) and the hepatitis C virus (HCV) are two common diseases in the western world. 30-40% of patients with ALD suffer from HCV and 70% of HCV patients are heavy drinkers. The association between the two diseases accelerates the chain of events that leads to liver cirrhosis and hepatocellular carcinoma (HCC). The reason for this is that the two diseases have a synergistic effect on oxidative stress, the immune component, and the mechanisms of carcinogenesis. The relative risk of liver cirrhosis and HCC has increased very significantly...

STAT3 and hexokinase II (HK-II) are involved in viral infection and carcinogenesis of various cancers including hepatocellular carcinoma (HCC). The roles of STAT3 and HK-II in hepatitis B virus (HBV)- and hepatitis C virus (HCV)-related HCC remain largely unclear. This study examined STAT3 and HK-II expression in HBV- and HCV-related HCC, HBV-related liver fibrosis, and normal control liver by using tissue microarray and immunohistochemical method. Results showed that STAT3 expression in HBV-related HCC, HCV-related HCC, and HBV-related liver fibrosis was significantly higher than in control liver (P < 0...
