Molecular and functional analysis of occult hepatitis B virus isolates from patients with hepatocellular carcinoma.
UNLABELLED Occult HBV infection is characterized by the persistence of HBV DNA in the liver of individuals negative for HBV surface antigen (HBsAg). Occult HBV may exist in the hepatocytes as a free genome, although the factors responsible for the very low viral replication and gene expression usually observed in this peculiar kind of infection are mostly unknown. Aims of this study were to inv...
متن کاملHepatitis C virus replication in hepatocellular carcinoma.
Hepatitis C virus (HCV) replication is reported in both tumour and non-tumour tissue in a case of hepatocellular carcinoma. Viral replication was established by showing the presence of minus strand HCV RNA by PCR amplification, after excluding residual reverse transcriptase activity of Taq polymerase. No minus strand was found in serum derived virion RNA. PCR amplified products from both tumour...
متن کامل[Hepatocellular carcinoma and hepatitis B virus].
Chronic hepatitis B is the most common cause of hepatocellular carcinoma (HCC) in Asia. Integration of hepatitis B virus (HBV) genome is likely an early event of carcinogenesis. The integrated HBV genome may activate neighboring cellular genes directly to offer a selective growth advantage to the liver cells. Production of hepatitis B X protein can act as a transactivator on various cellular ge...
متن کاملProteomic analysis of differentially expressed proteins in hepatitis B virus-related hepatocellular carcinoma tissues
BACKGROUND Hepatocellular carcinoma (HCC), a major cause of cancer death in China, is preceded by chronic hepatitis and liver cirrhosis (LC). Although hepatitis B virus (HBV) has been regarded as a clear etiology of human hepatocarcinogenesis, the mechanism is still needs to be further clarified. In this study, we used a proteomic approach to identify the differential expression protein profile...
متن کاملFull-length genomic sequence of hepatitis B virus genotype C2 isolated from a native Brazilian patient.
The hepatitis B virus (HBV) is among the leading causes of chronic hepatitis, cirrhosis and hepatocellular carcinoma. In Brazil, genotype A is the most frequent, followed by genotypes D and F. Genotypes B and C are found in Brazil exclusively among Asian patients and their descendants. The aim of this study was to sequence the entire HBV genome of a Caucasian patient infected with HBV/C2 and to...
