Long non-coding RNAs are involved with development and progression of cancer, and the advance of microarray technology allows the researchers to investigate the complete expression profile of lncRNA in various kinds of sample. We enrolled 5 male primary HCC cases with chronic HBV infection and the HCC and normal tissues have been obtained during the resection surgery. After total RNA extraction, the lncRNA microarray analysis was conducted to determine the lncRNA and mRNA expression signals. 612 lncRNAs and 1,064 mRNAs were significantly up-regulated in HCC tissue while 656 lncRNAs and 1,532 mRNAs were down-regulated in HCC tissues...

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...

:  Introduction and aim. Hepatocellular carcinoma (HCC) is the most common primary malignant liver tumor. It is primarily caused by hepatic cirrhosis or chronic viral hepatitis. Hepatic carcinogenesis is associated with increased oxidative stress. Thus, the aim of our study was to assess expression of the genes involved in the homeostasis of oxidative stress in patients with HCC. MATERIAL AND METHODS: The study was performed on 32 patients with primary HCC (verified by liver histology in 29 patients) and 27 control subjects (in 11 subjects, liver histology was available either with no or minimal changes in the liver tissue)...

BACKGROUND: The liver, as the main iron storage compartment and the place of hepcidin synthesis, is the central organ involved in maintaining iron homeostasis in the body. Excessive accumulation of iron is an important risk factor in liver disease progression to cirrhosis and hepatocellular carcinoma. Here, we review the literature on the molecular pathogenesis of iron overload and its clinical consequences in chronic liver diseases. DATA SOURCES: PubMed was searched for English-language articles on molecular genesis of primary and secondary iron overload, as well as on their association with liver disease progression...

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...

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related death worldwide. Hepatitis C virus (HCV) infection is the predominant cause of chronic liver diseases and HCC, particularly in Western countries. Multiple molecular mechanisms are involved in the development and progression of HCV-related HCC, of which oxidative stress plays a pivotal role. HCV infection induces overproduction of reactive oxygen species (ROS) and impairs the function of endogenous antioxidants. Excessive amount of ROS directly damages DNA, lipids and proteins...

Nonalcoholic fatty liver disease (NAFLD) is one of the most important chronic liver diseases worldwide and has garnered increasing attention in recent decades. NAFLD is characterized by a wide range of liver changes, from simple steatosis to nonalcoholic steatohepatitis, cirrhosis, and hepatocellular carcinoma. The blurred pathogenesis of NAFLD is very complicated and involves lipid accumulation, insulin resistance, inflammation, and fibrogenesis. NAFLD is closely associated with complications such as obesity, diabetes, steatohepatitis, and liver fibrosis...

BACKGROUND: Hepatocellular carcinoma (HCC) is the fifth most common cancer and the third leading cause of cancer death worldwide. It is a heterogeneous disorder and >80 % of the tumors develop in patients with liver cirrhosis, resulting from chronic inflammation and/or fibrosis. Here, we set out to identify novel targets for HCC therapy and to define a subgroup of patients that might benefit most from it. METHODS: Cellular pathway activation profiling of 45 transcription factors in a HCC-derived cell line (HEP3B), in vitro analysis of NFκB reporter activity in additional HCC-derived cell lines and pathway-focused integrative analyses of publicly available primary HCC-derived expression profiling data (GSE6764, GSE9843, E-TABM-36 and E-TABM-292) were employed to reveal a role of NFκB in HCC development...

Mallory-Denk bodies (MDBs) are hepatocytic protein aggregates found in steatohepatitis and several other chronic liver diseases as well as hepatocellular carcinoma. MDBs are mainly composed of phosphorylated keratins and stress protein p62/Sequestosome-1 (p62), which is a common component of cytoplasmic aggregates in a variety of protein aggregation diseases. In contrast to the well-established role of keratins, the role of p62 in MDB pathogenesis is still elusive. We have generated total and hepatocyte-specific p62 knockout mice, fed them with 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC) to induce MDBs and allowed the mice to recover from DDC intoxication on a standard diet to investigate the role of p62 in MDB formation and elimination...

Hepatocellular carcinoma (HCC) is the most common primary malignancy of the liver and is characterized by multistage formation. The presence of ductular reaction, cytokeratin 7 positivity (PCK7), and increased levels of gamma glutamyltransferase (γGT) has been observed during liver carcinogenesis and contribute to tumor progression. Our goal was to evaluate the ductular reaction in multistage carcinogenesis and to correlate PCK7 and γGT levels with tumor incidence, histological characteristics, liver DNA damage index, and the expression of oxidative stress proteins...

NAD(P)H: quinone oxidoreductase (NQO1) is essential for cell defense against reactive oxidative species, cancer, and metabolic stress. Recently, NQO1 was found in ribonucleoprotein (RNP) complexes, but NQO1-interacting mRNAs and the functional impact of such interactions are not known. Here, we used ribonucleoprotein immunoprecipitation (RIP) and microarray analysis to identify comprehensively the subset of NQO1 target mRNAs in human hepatoma HepG2 cells. One of its main targets, SERPINA1 mRNA, encodes the serine protease inhibitor α-1-antitrypsin, A1AT, which is associated with disorders including obesity-related metabolic inflammation, chronic obstructive pulmonary disease (COPD), liver cirrhosis and hepatocellular carcinoma...

Early chronic stress has enduring implications for physical and mental health outcomes. Hair cortisol concentration (HCC) has emerged as a marker of cumulative cortisol exposure, yet HCC in infants is not well understood. We examined how infant HCC relates to widely used basal salivary cortisol measures, maternal HCC, and environmental context in 111 infants assessed at 6 and 12 months of age. Maternal HCC at 6 and 12 months was correlated with infant HCC at 12 months. At 12 months, infant HCC was positively associated with waking salivary cortisol concentration (SCC), evening SCC, and area under the curve (AUC), but was independent of diurnal slope...

Alcoholic and virus C hepatitis currently represent the main causes of chronic liver disease worldwide. Every year many people die and are subjected to complex hospitalization and medical assistance due to these pathologies. Alcoholic liver disease and hepatitis C virus chronic infection are often present in the same patient. These two pathologies sinergically act in determining the onset and progression of liver damage that, from the chronic hepatitis staging, may rapidly progress to fibrosis, cirrhosis and hepatocellular carcinoma...

Hepatocellular Carcinoma (HCC) is a major healthcare problem. Almost ninety percent of HCCs develops on cirrhosis due to chronic viral hepatitis, Non-Alcoholic Steatohepatitis (NASH) and alcohol abuse. Alcohol itself is defined a strong human carcinogenic agent. Some genetic polymorphisms in alcohol-metabolizing systems and more recently, some sequence variations within the genes coding for patatin-like phospholipase encoding 3 (PNPLA3) and Transmembrane 6 superfamily 2 (TM6SF2), have been found to promote liver fibrosis in alcohol abuse, until HCC development...

BACKGROUND AND AIM: Nonalcoholic fatty liver disease (NAFLD) is a chronic liver disease worldwide, ranging from simple steatosis to nonalcoholic steatohepatitis, which may progress to cirrhosis, eventually leading to hepatocellular carcinoma (HCC). HCC ranks as the third highest cause of cancer-related death globally, requiring an early diagnosis of NAFLD as a potential risk factor. However, the molecular mechanisms underlying NAFLD are still under investigation. So far, many in vitro studies on NAFLD have been hampered by the limitations of 2D culture systems, in which cells rapidly lose tissue-specific functions...

Liver sinusoidal endothelial cells (LSECs) are highly specialized endothelial cells representing the interface between blood cells on the one side and hepatocytes and hepatic stellate cells on the other side. LSECs represent a permeable barrier. Indeed, the association of fenestrae, absence of diaphragm and lack of basement membrane make them the most permeable endothelial cells of the mammalian body. They also have the highest endocytosis capacity of human cells. In physiological conditions, LSECs regulate hepatic vascular tone contributing to the maintenance of a low portal pressure despite the major changes in hepatic blood flow occurring during digestion...
