BACKGROUND: Prior epidemiological evidences suggest that hepatitis B virus (HBV) infection is linked to cancers other than hepatocellular carcinoma. This prospective hospital registry-based case-control study aimed to investigate the sero-epidemiological association between chronic HBV infection and various types of cancer. METHODS: 95,034 patients with first-diagnosed non-hepatocellular malignancy in a tertiary hospital between 2007 and 2014; and 118,891 non-cancer individuals as controls from a health promotion center were included...

Extrahepatic syndromes are uncommon manifestations of acute and chronic hepatitis B. The pathogenesis likely involves an aberrant immunologic response to extrahepatic viral proteins. Antiviral therapy reduces the availability of these viral protein antigens and thus halts immune activation. Approximately 1% of all cases of acute inflammatory demyelinating polyneuropathy are associated with hepatitis B. Guillain-Barre syndrome (GBS) is a remarkably clinically diverse disorder with distinctive variants characterised by an immune-mediated attack to components of the peripheral nervous system...

Background/Aims: MicroRNA-125b (miR-125b) has been found to regulate inflammation and acts as an oncogene in many cancers. The mechanisms of miR-125b expression during hepatitis C virus (HCV) infection remain to be clarified. The present study aims to identify the factors that might regulate miR-125b expression in HCV infection. Results: High expression of miR-125b was found to correlate with HCV infection in replicon cells and in sera from HCV-infected patients, whereas the miR-125b inhibitor reduced HCV gene expression...

Introduction: Hepatocellular carcinoma (HCC) is one of the most prevalent primary malignant tumors and accounts for about 90% of all primary liver cancers. Its distribution varies greatly according to geographic location and it is more common in middle and low- income countries than in developed ones especially in Eastern Asia and Sub Saharan Africa (70% of all new HCCs worldwide), with incidence rates of over 20 per 100,000 individuals. Explanation: The most important risk factors for HCC are Hepatitis B Virus (HBV) infection, Hepatitis C Virus (HCV) infection, excessive consumption of alcohol and exposition to aflatoxin B1...

Molecular mechanisms of liver pathology and clinical disease in HEV infection remain unclear. MicroRNAs are known to modulate viral pathogenesis either by directly altering viral gene expression or by enhancing cellular antiviral responses. Given the importance of microRNA-122 (miR-122) in liver pathobiology, we investigated possible role of miR-122 in HEV infection. In silico predictions using genotype 1, 2, 3 and 4 HEV sequences showed that majority of genomes (203/222) harbor at least one miR-122/miR-122* target site...

HL1-hT1 cell line represents adult human liver stem cells (LSCs) immortalized with human telomerase reverse transcriptase. In this study, HL1-hT1 cells were found to express mesenchymal markers (vimentin, CD73, CD90/THY-1 and CD105) and an early hepatic endoderm marker FOXA2, while not expressing hepatic progenitor (HNF4A, LGR5, α-fetoprotein) or differentiated hepatocyte markers (albumin, transthyretin, connexin 32). In response to microcystin-LR (MC-LR), a time- and concentration-dependent formation of MC-positive protein bands in HL1-hT1 cells was observed...

BACKGROUND: Diagnosis of de novo immune hepatitis (dnIH) after liver transplantation relies on biopsy findings, with an abundance of plasma cells (PCs) in the inflammatory infiltrates a hallmark of the disease. Very little is known about what other types of immune cells exist in the infiltrates mainly located in the portal areas of the liver tissue. METHODS: We analyzed the composition of T cells, B cells, PCs, and macrophages in the liver biopsies of 12 patients with dnIH, 9 of them obtained at the time of diagnosis...

Nucleoside analogs represent the largest class of small molecule-based antivirals, which currently form the backbone of chemotherapy of chronic infections caused by HIV, hepatitis B or C viruses, and herpes viruses. High antiviral potency and favorable pharmacokinetics parameters make some nucleoside analogs suitable also for the treatment of acute infections caused by other medically important RNA and DNA viruses. This review summarizes available information on antiviral research of nucleoside analogs against arthropod-borne members of the genus Flavivirus within the family Flaviviridae, being primarily focused on description of nucleoside inhibitors of flaviviral RNA-dependent RNA polymerase, methyltransferase, and helicase/NTPase...

Alcohol liver disease (ALD) is one of the major chronic liver diseases worldwide, ranging from fatty liver, alcoholic hepatitis, cirrhosis, and potentially hepatocellular carcinoma. Epidemiological studies suggest a potential link between ALD and impaired circadian rhythms, but the role of hepatic circadian proteins in the pathogenesis of ALD remains unknown. Here we show that the circadian clock protein BMAL1 in hepatocytes is both necessary and sufficient to protect mice from alcohol liver disease. Ethanol diet-fed mice with liver-specific knockout (Bmal1-LKO) or depletion of Bmal1 develop more severe liver steatosis and injury as well as a simultaneous suppression of both de novo lipogenesis and fatty acid oxidation, which can be rescued by the supplementation of synthetic PPARα ligands...

There are estimated 248 million individuals worldwide persistently infected with hepatitis B virus (HBV), if without timely and effective treatment, about 25%-40% of whom would develop to liver cancer, cirrhosis or other HBV related end-stage liver diseases. Our previously study has reported a unique antibody named E6F6, that recognizes HBsAg-aa119-125 and is capable of prolonged suppression of HBsAg and HBV DNA levels in mice. In this study, data revealed that the consecutive E6F6 treatments can not only effectively inhibit HBV viremia, but also significantly reduce HBV-induced hepatocarcinogenesis in DEN-treated HBV-Tg mice...

It remains unclear whether hepatitis B virus (HBV) infection may modify the severity of viral steatosis in patients coinfected with chronic hepatitis C virus (HCV). We examined the influence of coinfection with HBV on prevalence of steatosis in chronic hepatitis C in a multi-center cohort of HBV-HCV subjects, and by performing a systematic review and meta-analysis of the literature. We centrally and blindly assessed steatosis prevalence and severity in a cohort of HBV-HCV coinfected subjects compared to HCV and HBV monoinfected controls and we performed a systematic review of studies addressing the prevalence of steatosis in HBV-HCV subjects compared to HCV controls...

Previous studies have focused on the relationship between hepatitis B virus (HBV) infection and non-Hodgkin lymphoma (NHL). However, the results remain inconsistent and somehow conflicting in different sub-groups. The aim of this study was to combine the findings of independent studies to comprehensively assess the association between HBV and NHL using a meta-analysis. Relevant studies were identified through structured keyword searches in PubMed, EMBASE and the China National Knowledge Infrastructure (CNKI) database and 58 studies with a total of 53,714 NHL cases and 1,778,591 controls were finally included...

HBeAg seroconversion marks an important spontaneous change and treatment end-point for HBeAg-positive patients and is a pre-requisite for HBsAg loss or functional cure. In this retrospective analysis, we aimed to identify predictors of seroconversion using serum quantitative HBsAg and HBcrAg, in HBeAg-positive patients treated with nucleos(t)ide analogues (NA). Data and samples from 118 HBeAg-positive adults (genotypes A-G) started on NA between Jan 2005-Sept 2016 were retrospectively analysed at several time-points...

Hepatocellular carcinoma (HCC) is among the most common lethal cancers of the digestive system with poor prognosis rates and ineffective therapeutic options. Matrine, a traditional Chinese medicine found in the roots of sophora species, has been used in the clinical treatment of liver fibrosis, chronic hepatitis B and other diseases. We have synthesized a matrine derivatives named WM622 (C26H35ON3S2) with a significant inhibitory effect on transplanted tumors in vivo. The half inhibitory concentration (IC50) of WM622 is 34 µM, which is much lower than matrine...

Fibrolamellar hepatocellular carcinoma (FL-HCC) is a rare variant of hepatocellular carcinoma. It is commonly reported in the younger population with no underlying chronic liver disease and free of viral Hepatitis B and C. Local recurrence and distant metastasis are common despite better prognosis compared to conventional hepatocellular carcinoma. Complete surgical resection is associated with higher median survival and is the mainstay treatment option for localized FL-HCC. Multi-modality therapies such as TACE can be used to downstage upfront unresectable FL-HCC...

Norovirus infections are a significant health and economic burden globally, accounting for hundreds of millions of cases of acute gastroenteritis every year. In the absence of an approved norovirus vaccine, there is an urgent need to develop antivirals to treat chronic infections, and provide prophylactic therapy to limit viral spread during epidemics and pandemics. Toll-like receptor (TLR) agonists have been explored widely for their antiviral potential and several are progressing through clinical trials for the treatment of human immunodeficiency virus (HIV), hepatitis B virus (HBV) and as adjuvants for norovirus virus-like particle (VLP) vaccines...

Hepatitis B virus (HBV) is the one of the major causes of chronic liver disease. Individuals exposed to HBV show wide spectrum outcomes including immunized persons, asymptomatic carrier, chronic active hepatitis, cirrhosis and HCC. The outcome of HBV infection and the severity of associated liver diseases are determined by the nature and strength of host immune responses against the virus. There is accumulating evidence that the innate branch of the host immune system plays an important role in the control of HBV infection...
