Alpha virus M1 is an oncolytic virus that targets zinc-finger antiviral protein (ZAP)-defective cancer cells, and may be useful for treatment of hepatocellular carcinoma (HCC). Most of HCC patients have hepatitis and need long-term antiviral medication. Thus, it is necessary to clarify whether anti-virus medicines influence oncolytic effect of M1. We examined the effect of drugs used to treat hepatitis B/C on M1-mediated oncolysis in vitro and in vivo. Interferon (IFN)-α induces expression of antiviral IFN-stimulated genes (ISGs) in HCC cells with moderate sensitivity to M1 virus...

Chronic liver diseases (CLDs), due to chronic hepatitis C; hepatitis B; nonalcoholic fatty liver diseases (NAFLD); and alcoholic liver disease, are a leading cause of morbidity and mortality globally. Early identification of patients with cirrhosis at high risk of progression to liver-related complications may facilitate timely care and improve outcomes. With risks and misclassification associated with invasive tests, such as liver biopsy, noninvasive imaging modalities for liver fibrosis assessment have gained popularity...

Background: Direct-acting antiviral agents (DAAs) are used increasingly to treat hepatitis C virus (HCV) infection. Reports were published recently on hepatitis B virus (HBV) reactivation (HBV-R) in patients with HBV-HCV co-infection. Hepatitis B virus reactivation, defined as an abrupt increase in HBV replication in patients with inactive or resolved HBV infection, may result in clinically significant hepatitis. Objective: To assess whether HBV-R is a safety concern in patients receiving HCV DAAs...

BACKGROUND AND AIMS: While HBV and HCV are risk factors for HCC, uncertainty exists as to whether these viral infections have prognostic significance in HCC. Thus, we compared the overall survival of patients with HBV, HCV, and non-viral HCC, and evaluated whether the presence of HBV and HCV predicts patient outcomes. METHODS: We conducted a multi-center study of HCC cases diagnosed at six Melbourne tertiary hospitals between Jan 2000-Dec 2014. Patient demographics, liver disease and tumor characteristics, and patient outcomes were obtained from hospital databases, computer records and the Victorian Death Registry...

Hepatocellular carcinoma (HCC) is the most prevalent primary liver cancer and its incidence is on the rise largely attributed to Hepatitis C virus (HCV) related liver cancer. A distinct feature of HCV associated HCC is the substantially increased incidence of metastasis compared to non-viral or HBV associated HCC. Nm23-H1 is the first reported human metastasis suppressor down-regulated in many human metastatic cancers. Nm23-H1 functions are modulated in several virus associated cancers. Our study now shows that HCV E1 protein expression as well as HCV infection induces pro-metastatic effect on cancer cells which is simultaneous to Nm23-H1 transcriptional down-regulation and Nm23-H1 protein degradation...
